Plug-In Solar Panels UK 2026 – Costs, 800W Rules, Savings & How They Work
Plug-in solar panels are now legal to buy and use in Great Britain under new rules that came into force on 27 August 2026. They provide a much smaller and lower-cost alternative to conventional rooftop solar, allowing a compliant solar device to connect to a suitable household mains socket.
Plug-in solar is particularly relevant for renters, flats, apartments, smaller homes, households without a suitable roof and people looking for a lower-cost way into solar generation.
Under the new framework, a compliant plug-in solar device can supply a maximum of 800VA of AC power into the household electrical installation, with current limited to 3.5A. The solar panels themselves can have a higher combined capacity, up to 2,000W.
The UK Government says plug-in solar could provide up to 20% of an average home's electricity use and potentially save households up to £110 a year, although actual savings will depend on the property, solar exposure and how much electricity is used while the panels are generating.
The first systems are now being listed by major UK retailers. Argos currently lists plug-in solar kits from around £599, with several system sizes available to order.
Important: 800W does not necessarily mean 800W of solar panels
The 800W limit applies to the power supplied to the home's electrical installation, not necessarily the total wattage printed on the solar panels. This is why some UK plug-in solar kits contain 890W, 1,030W or even 1,260W of solar panel capacity while using an inverter that limits mains output to the permitted level.

Plug-in solar UK latest update – August 2026
The position changed significantly on 27 August 2026, when compliant plug-in solar devices became legal to buy and use in Great Britain.
Legal from 27 August 2026
Households in England, Scotland and Wales can now use compliant plug-in solar devices that meet the new technical, electrical and product safety requirements.
800VA maximum output
A plug-in solar device can supply a maximum of 800VA to the household electrical installation, with current limited to 3.5A.
Up to £110 annual saving
Government estimates suggest savings could reach £110 a year, depending on electricity use, location, orientation, shading and system performance.
Products now being listed
Major UK retail listings have begun appearing, giving consumers their first clear view of real-world plug-in solar prices and system sizes.
The important point for consumers is that not every solar panel, microinverter or European balcony solar kit can legally be plugged into a UK socket. The complete device must meet the applicable GB plug-in solar requirements.
What are plug-in solar panels?
Plug-in solar panels are compact photovoltaic systems designed to generate electricity for use inside a home without requiring the same type of permanent electrical installation as conventional rooftop solar.
A typical system includes one or more solar panels, a microinverter, a manufacturer-supplied cable and plug, and an approved mounting system.
The solar panels generate DC electricity. The microinverter converts this into AC electricity suitable for use within the home.
The compliant device is then connected to an appropriate household socket using the plug supplied by the manufacturer.
Electricity generated by the solar panels is available to appliances within the home while it is being produced, reducing the amount of electricity that needs to be drawn from the grid at that moment.
Plug-in solar has already become established in several European countries, with balcony and small-scale solar particularly popular in Germany.
Are plug-in solar panels legal in the UK?
Compliant plug-in solar devices became legal to buy and use in Great Britain from 27 August 2026.
The new framework covers England, Scotland and Wales. Northern Ireland has separate electricity network arrangements, so consumers there should check the current Northern Ireland requirements before buying or connecting a plug-in solar product.
The change combines amendments to electrical regulations with a dedicated Plug-In Solar Device Interim Product Specification.
The specification defines the electrical, product, connection, mounting and safety requirements a plug-in solar device must meet.
Maximum AC output
800VA supplied to the mains electrical installation.
Maximum current
The current supplied to the household circuit must not exceed 3.5A.
Maximum panel capacity
The combined rated DC capacity of the solar panels can be up to 2,000W.
Over 960W of panels
Where total PV module capacity exceeds 960W, consumers should consider having the existing electrical installation professionally assessed before installation.
How many plug-in solar systems can you have?
This is an important detail.
The product specification has been designed to allow one plug-in solar device on a suitable household final circuit. However, the current G98 network connection requirements restrict this to one plug-in solar device per household.
Consumers should therefore not buy several 800W systems and plug them into different household sockets unless the network rules are subsequently changed and the manufacturer confirms the arrangement is permitted.
For these purposes, a household means a dwelling with its own electricity supply and consumer unit. A flat with its own consumer unit is therefore treated as a separate household.
How do you know if a plug-in solar kit is UK compliant?
A product being described online as plug and play solar, balcony solar or an 800W microinverter kit does not by itself mean that it complies with the GB plug-in solar rules.
Manufacturers are required to have compliant devices type tested against the applicable G98 requirements and registered on the Energy Networks Association Type Test Register. The device must have been assessed and identified as compliant before being placed on the market under the plug-in solar framework.
Before buying a plug-in solar system
- Check the complete device is intended for the GB plug-in solar market
- Check the exact model has the required compliance documentation
- Check its G98 status rather than relying only on an advert or marketplace description
- Use the manufacturer-supplied plug, cables and approved components
- Follow the exact mounting instructions for that product
A compliant device uses a manufacturer-fitted, non-rewireable UK plug designed to the appropriate BS 1363 requirements, with additional safety measures required for electricity-generating equipment.
The plug must incorporate a BS 1362 fuse not exceeding 5A.
How do plug-in solar panels work?
Plug-in solar uses the same photovoltaic principle as conventional solar panels. Daylight is converted into electrical energy and that electricity contributes towards the power being used inside the property.
| Component | What it does |
|---|---|
| Solar panel | Generates DC electricity from daylight |
| Microinverter | Converts DC electricity into household AC electricity |
| Mounting system | Secures the panel in one of the positions approved for that product |
| Manufacturer-supplied cable | Connects the inverter safely to the mains connection |
| Approved UK plug | Connects the complete device to a suitable BS 1363 household socket |
| Monitoring system | Some products provide app-based generation and performance monitoring |
If, for example, the home is using electricity while the solar panels are producing power, the solar electricity contributes towards that demand. The property then needs to import less electricity from the grid.
Plug-in solar is therefore primarily designed to reduce grid electricity consumption, not provide all of the electricity required by an average household.
800W plug-in solar panels UK – what does the limit mean?
The headline limit for GB plug-in solar is 800VA. In normal consumer descriptions this is commonly referred to as the 800W plug-in solar limit.
The crucial distinction is between:
- Solar panel capacity – the rated DC capacity of the panels
- Inverter output – the AC electricity supplied into the household installation
The inverter must limit the power supplied to the mains installation to no more than 800VA, but the panels can have a combined rated capacity of up to 2,000W.
515W panels
A compact single-panel system may have less solar panel capacity than the maximum permitted inverter output.
890W panels
The panels can exceed 800W while the inverter continues to cap household AC output at the permitted maximum.
1,030W–1,260W panels
Higher panel capacity can help the inverter reach useful output for longer during less-than-perfect solar conditions.
Why would you install more than 800W of panels?
Solar panels rarely operate at their laboratory-rated maximum output throughout the day.
Cloud, winter sunlight, panel angle, temperature, shading and orientation all affect output.
Using more panel capacity can therefore help an 800VA inverter produce more useful electricity during periods when sunlight is weaker, while the inverter still prevents the AC output from exceeding the permitted maximum.
Where the total panel capacity exceeds 960W, the manufacturer should advise the consumer to consider a professional assessment of the existing electrical installation before installation.
How much do plug-in solar panels cost in the UK?
The arrival of mainstream retail listings has provided the first useful indication of real UK plug-in solar prices.
At the end of August 2026, Argos was listing UKSOL plug-in solar systems from approximately £599 to £989 for several hybrid-mount kits.
| Example system | Total solar panel capacity | Price seen August 2026 |
|---|---|---|
| UKSOL Pro Compact | 515W | £599 |
| UKSOL Pro Duo | 890W | £849 |
| UKSOL Pro Plus | 1,030W | £899 |
| UKSOL Pro Max | 1,260W | £989 |
Prices checked: 29 August 2026. Retail prices, product specifications, delivery dates and availability can change.
These initial prices place plug-in solar well below the cost of most full rooftop solar installations, although conventional rooftop systems normally have far greater electricity-generating capacity.
For comparison, see: Solar Panel Costs UK .
Where can you buy plug-in solar panels in the UK?
The mainstream retail market is beginning to open.
Argos is currently listing a range of plug-in solar products, giving consumers a clear indication of the first systems and prices entering the GB market.
At the time of our August 2026 check, some Argos products were available to order with estimated delivery later in 2026 rather than for immediate collection.
Government announcements have also identified major retailers preparing for the plug-in solar market, so product choice and competition are likely to increase.
Do not choose on wattage and price alone
A cheap imported solar kit may look very similar to a compliant plug-in solar device but still fail to meet the GB requirements.
Check the exact model and complete system, rather than assuming that any 800W microinverter or European balcony solar kit can legally be plugged into a household socket.
Is every plug-in solar system suitable for a balcony?
No.
The terms plug-in solar and balcony solar are often used together, but the approved mounting locations depend on the specific product.
Some current UK retail products are intended for ground or suitable solid-wall mounting and are not approved by their manufacturer for balcony mounting. Always check the installation instructions for the exact kit.
Do plug-in solar panels need to be registered with the DNO?
Yes. Plug-in solar is easier to connect than conventional rooftop solar, but it is still electricity-generating equipment operating in parallel with the distribution network.
After installation, the relevant Distribution Network Operator (DNO) should be notified. For the normal connect-and-notify route, notification is generally required within 28 days of installation.
The DNO is the network company responsible for the electricity cables and infrastructure supplying the property. It is not necessarily the same company that sends the household electricity bill.
Remember the 28-day notification
Buying a compliant system does not remove the network notification requirement. Follow the registration instructions supplied with the product and notify the appropriate DNO after connection.
How much electricity can plug-in solar panels generate?
Generation varies according to the amount of solar panel capacity, location, orientation, panel angle, shading, weather and equipment performance.
As a broad illustration, an 800W-class plug-in solar system in suitable UK conditions may generate around 500–800kWh per year. Actual output can be substantially lower where panels are shaded or poorly positioned.
South-facing
A sunny south-facing position with minimal shading can provide the strongest generation potential.
East or west facing
Useful generation is still possible, with more output concentrated in the morning or afternoon.
Heavily shaded
Nearby buildings, balcony structures, trees and other obstructions can substantially reduce generation.
Output will also vary significantly throughout the year. Summer generation will normally be much higher than output during the darker winter months.
How much can plug-in solar save on electricity bills?
The UK Government says a plug-in solar system could potentially save a household up to £110 a year and provide up to 20% of an average home's electricity use.
These figures should be treated as potential rather than guaranteed savings.
The biggest factor is self-consumption – how much of the solar electricity is actually being used inside the home at the time it is generated.
Home workers
Computers, monitors, lighting, cooking and other daytime loads may make it easier to use solar electricity as it is generated.
Continuous household loads
Fridges, freezers, routers and other appliances consume electricity throughout the day and can use part of the solar output.
Evening-heavy homes
Households using most of their electricity after sunset may achieve lower savings because solar production has already fallen away.
Plug-in solar therefore tends to make the most financial sense where the property has useful daylight exposure and regular daytime electricity demand.
For larger installations, see our: Solar Panel Payback Guide .
Can you get paid for exporting plug-in solar electricity?
A plug-in solar system can sometimes generate more electricity than the home is using at that moment, which may result in a small amount of electricity flowing back to the grid.
However, consumers should not assume that buying a compliant plug-in solar kit automatically qualifies them for Smart Export Guarantee payments.
Solar PV is an eligible technology under the Smart Export Guarantee (SEG), but a generator still needs to meet the applicable eligibility, certification and metering requirements of the scheme and the chosen SEG supplier.
The practical position for new plug-in solar installations may also vary between export tariff providers as the market develops.
For most small plug-in systems, the clearest financial benefit is therefore likely to come from using the solar electricity in the home and avoiding the cost of importing that electricity from the grid.
If export payments are important to your buying decision, check eligibility with the relevant SEG provider before purchasing a system.
See: Best SEG Rates UK .
Balcony solar panels UK
Balcony solar is one of the major reasons plug-in solar has attracted so much interest.
People living in flats and apartments often have no control over the main roof of their building, making a conventional rooftop solar installation difficult or impossible.
Where an approved product and suitable mounting location are available, plug-in solar can potentially give some flat residents access to their own renewable electricity generation for the first time.
South-facing balconies
Good sunlight and limited shading can create strong small-scale solar potential.
East and west facing
These locations can still provide useful generation, particularly during mornings or afternoons.
Shaded balconies
Deep balconies and surrounding buildings can substantially reduce solar output.
However, the fact that plug-in solar is now electrically permitted does not mean that every balcony installation is automatically allowed or safe.
Landlord or freeholder permission, lease conditions, building management rules, planning considerations, structural suitability, wind loading and fire safety can all affect what can be installed.
The exact product must also be approved by its manufacturer for the intended mounting arrangement.
See: Solar Panels for Flats UK .
Plug-in solar panels for renters
Renters have traditionally had limited access to solar because conventional rooftop systems are permanent installations requiring the property owner's involvement.
Plug-in solar offers a potentially more accessible alternative because the systems are smaller, less expensive and may be easier to remove if the occupant moves home.
Potential advantages
- Lower upfront cost than full rooftop solar
- Smaller and potentially removable
- Can reduce daytime grid electricity consumption
- Does not require ownership of the main roof
Important restrictions
- Landlord permission may still be required
- Tenancy conditions can restrict alterations
- Building management or freeholder rules may apply
- Panels must be mounted safely
- The complete electrical device must be GB compliant
Renters should therefore check their tenancy agreement and obtain any necessary permission before mounting panels or making changes to the property.
Where can plug-in solar panels be installed?
The allowed locations depend on the exact system and the mounting arrangements approved by its manufacturer.
Gardens
Ground-mounted panels can work well where there is secure outdoor space, good sunlight and an approved mounting arrangement.
Solid walls
Some plug-in solar kits are designed for secure wall mounting using the manufacturer's specified fixings.
Balconies
Possible with systems specifically designed and approved for the relevant balcony mounting arrangement.
Outbuildings and garden offices
These can potentially offer useful panel locations where the product, electrical connection and mounting arrangement are suitable.
Do not assume a solar panel can simply be leaned against a wall, hung from a balcony or secured using improvised brackets.
Wind loading and falling-object risks mean the mounting system is an important part of the approved plug-in solar device.
Do plug-in solar panels need planning permission?
Planning considerations depend on the property, location and how the solar panels are mounted.
Small solar installations may fall within existing permitted development rules in many circumstances, but different restrictions can apply to listed buildings, conservation areas, flats, leasehold properties and unusual mounting arrangements.
Planning permission is also separate from landlord, freeholder or building management consent.
If there is any doubt, check the position with the relevant local planning authority before installing the panels.
Plug-in solar vs traditional rooftop solar panels
Plug-in solar and conventional rooftop solar solve different problems.
| Feature | Plug-in solar | Traditional rooftop solar |
|---|---|---|
| Typical upfront cost | Hundreds of pounds | Usually several thousand pounds |
| AC generation size | Maximum 800VA under plug-in rules | Typically several kilowatts |
| Installation | Designed for straightforward connection when using an approved complete device | Professionally installed fixed system |
| Typical customer | Renters, flats, smaller homes and lower-cost solar users | Homeowners with suitable roof space |
| Electricity generation | Small contribution to household demand | Can provide a significant proportion of annual household electricity |
| Battery storage | Excluded from the current simplified plug-in solar framework | Established option |
| Export potential | Relatively small | Can be substantial with larger arrays |
| SEG payments | Do not assume automatic eligibility | Commonly available where scheme requirements are met |
Which type of solar is better?
Neither is automatically better for every home.
For a renter, flat resident or household unable to install rooftop solar, a plug-in system may provide a realistic way to begin generating renewable electricity.
For a homeowner with good roof space and higher electricity use, a professionally installed rooftop system can generate far more electricity and can be combined with battery storage, EV charging and export tariffs.
That means homeowners should compare the cost and likely savings of both approaches rather than assuming that the cheapest initial purchase provides the best long-term return.
Plug-in solar vs portable solar panels
Plug-in solar should not be confused with the portable solar panels commonly used for camping, caravans and portable power stations.
| Feature | Plug-in solar | Portable solar |
|---|---|---|
| Main purpose | Supply solar electricity into the household electrical installation | Charge portable equipment or power stations |
| Typical location | Garden, wall, balcony or suitable property exterior | Camping, caravans and temporary outdoor use |
| Connection | Approved household mains connection | Normally connected to portable equipment |
| Primary benefit | Reduce household grid electricity consumption | Provide portable or off-grid electricity |
Can plug-in solar panels work with battery storage?
The current GB plug-in solar framework applies specifically to plug-in solar devices without battery storage.
Plug-in battery systems and plug-in solar devices integrated with battery storage are outside the scope of the current Interim Product Specification.
Consumers should therefore not assume that a battery can simply be connected to a compliant plug-in solar system while remaining within the same simplified rules.
Conventional fixed home battery systems remain widely available for professionally installed home solar systems.
Can plug-in solar panels charge an electric car?
A plug-in solar system can contribute towards the overall electricity being used by a household, but its maximum output is small compared with the energy required for regular EV charging.
An 800VA plug-in solar device should therefore not be viewed as a dedicated solar EV-charging solution.
Homes with an electric car and suitable roof space may gain more from a larger rooftop solar array, potentially combined with battery storage and smart EV charging.
Are plug-in solar panels safe?
The GB framework was introduced after technical work examining whether small plug-in solar devices could operate safely with UK domestic electrical installations.
The Interim Product Specification includes requirements covering the inverter, plug, cables, electrical protection, anti-islanding, mounting system, fire performance and product documentation.
Safety still depends on consumers using the correct compliant product in the way its manufacturer intended.
Buy a compliant complete system
Do not construct a plug-in solar device by mixing unrelated imported panels, microinverters, plugs and cables.
Use the wall socket directly
Extension cables, multi-way adaptors, travel adaptors and RCD adaptors are not permitted under the product specification.
Use approved mounting equipment
Panels must be secured using the mounting arrangements and components specified for that product.
Check the electrical installation
If the wiring is old, unusual or its condition is uncertain, obtain professional electrical advice before connecting generation equipment.
Outdoor sockets and balcony fire safety
Outdoor electrical connections must be suitable for outdoor use. Current fire-safety guidance recommends a properly installed minimum IP65-rated outdoor socket where an outdoor connection is required.
Any new outdoor socket or alteration to the fixed electrical installation should be carried out by a competent installer.
Solar equipment should not block windows, shared balconies, walkways or fire escape routes. Current fire-safety guidance also advises against installing panels on combustible external wall systems or timber balconies.
Can you use an extension lead with plug-in solar?
No. The Government's product specification states that extension cables, multi-way adaptors, travel adaptors and RCD adaptors are not permitted.
The device should connect using the manufacturer-supplied connection arrangement to an appropriate fixed socket.
Are plug-in solar panels worth it?
Plug-in solar is unlikely to replace conventional rooftop solar for a homeowner with a large suitable roof, but that is not really the market it is designed to serve.
Its strongest use cases are households that previously had few practical ways to generate solar electricity themselves.
More likely to make sense
- Renters with permission and suitable outdoor space
- Flat residents without access to the main roof
- Homes with unsuitable roofs
- Households with regular daytime electricity consumption
- People wanting to spend hundreds rather than thousands initially
Less attractive where
- The panels would be heavily shaded
- Almost all electricity is used after sunset
- There is nowhere safe and approved to mount the panels
- A homeowner has an excellent roof and would benefit more from a larger system
- The household expects plug-in solar to cover most of its electricity demand
The right comparison is therefore not simply “Is £599 cheap for solar?” but:
How much electricity will this system realistically generate at my property, how much of it will I use, and what other solar options are available to me?
Plug-in solar or full rooftop solar?
Plug-in solar provides a much lower-cost route into electricity generation, particularly for homes that cannot install a conventional system.
If you own a property with suitable roof space, it is still worth comparing the economics with a larger rooftop solar installation before deciding.
The future of plug-in solar in the UK
Plug-in solar opens a new part of the domestic renewable energy market.
Until now, access to household solar has been strongly linked to owning a suitable roof and being able to fund a professionally installed system costing several thousand pounds.
Smaller plug-in systems reduce that entry cost considerably and could extend solar generation to renters, flat residents and households unable to install conventional rooftop arrays.
The market is still at a very early stage. Prices, product choice, mounting solutions, network arrangements and supplier policies are likely to develop as more systems are approved and real-world experience grows.
For that reason, buyers should base decisions on the current rules and the exact product being purchased rather than older articles about proposed plug-in solar arrangements or overseas systems.

Are plug-in solar panels legal in the UK?
Compliant plug-in solar devices became legal to buy and use in Great Britain from 27 August 2026. The framework covers England, Scotland and Wales. Northern Ireland has separate network arrangements that should be checked before connection.
What is the maximum size of a plug-in solar system?
The maximum AC apparent power supplied into the household electrical installation is 800VA, with current limited to 3.5A. The combined rated DC capacity of the solar panels can be up to 2,000W.
Why are some plug-in solar kits rated at more than 800W?
The wattage advertised for a kit may refer to the combined rated capacity of its solar panels. The inverter can still restrict the electricity supplied into the home to the permitted 800VA maximum.
Do I need an electrician to install plug-in solar?
A compliant plug-in solar device is specifically designed so that an ordinary consumer can install and connect it according to the manufacturer's instructions without the type of fixed electrical installation required for conventional rooftop solar.
However, alterations to fixed wiring or the installation of a new outdoor socket should be carried out by a competent person. Professional assessment should also be considered where total panel capacity exceeds 960W or where the existing electrical installation is old or uncertain.
How much do plug-in solar panels cost?
Early mainstream UK retail systems are currently priced in the hundreds of pounds. At the end of August 2026, Argos was listing several UKSOL systems from approximately £599 to £989, depending on panel capacity and kit configuration.
How much can plug-in solar save?
The UK Government says household savings could reach up to £110 per year. Actual savings depend on sunlight, orientation, shading, electricity prices, system cost and how much solar electricity is consumed within the home.
Can plug-in solar provide 20% of my electricity?
Government estimates suggest plug-in solar could provide up to 20% of the electricity used by an average home. This should not be treated as a guarantee. Individual properties and electricity-use patterns vary considerably.
Can I install more than one plug-in solar kit?
Consumers should currently work on the basis of one plug-in solar device per household. Although the product specification provides for one device per suitable final circuit, the current G98 network requirements restrict this to one per household unless those requirements are amended.
Can I plug solar into any household socket?
No. The exact installation and socket must meet the requirements stated by the manufacturer. The device must be connected using its approved manufacturer-supplied plug and connection arrangement.
Can I use an extension lead?
No. Extension cables, multi-way adaptors, RCD adaptors and travel adaptors are not permitted for plug-in solar under the current product specification.
Do plug-in solar panels need DNO registration?
Yes. The relevant Distribution Network Operator should be notified after installation. For a normal connect-and-notify installation, notification is generally required within 28 days.
Can I use plug-in solar in a flat?
Potentially, yes. Flats and apartments are one of the main potential use cases. However, landlord or freeholder permission, lease conditions, building management rules, fire safety, mounting requirements and planning considerations may still apply.
Can renters install plug-in solar?
Potentially. Plug-in solar is much more accessible to renters than conventional rooftop solar, but tenants should check their tenancy agreement and obtain any required landlord permission before mounting equipment on the property.
Are all plug-in solar panels suitable for balconies?
No. Some systems are intended only for ground or suitable wall mounting. Check the permitted mounting types for the exact product rather than assuming that every plug-in solar device is a balcony solar kit.
Can I plug a European balcony solar system into a UK socket?
Do not assume so. A device that is legal elsewhere in Europe does not automatically meet the GB product and network requirements. Check the compliance status of the exact complete system before buying it for household plug-in use.
Can plug-in solar work with batteries?
The current simplified GB framework applies to plug-in solar without batteries. Plug-in battery products and solar devices integrated with plug-in batteries are outside the scope of the current Interim Product Specification.
Can plug-in solar charge an electric car?
It can contribute towards the electricity being consumed by the home, but an 800VA system is small compared with typical EV charging demand. It should not be viewed as a dedicated replacement for a larger rooftop solar system used alongside an EV charger.
Can I receive Smart Export Guarantee payments?
Do not assume that a plug-in solar purchase automatically qualifies for SEG payments. Solar PV is an eligible SEG technology, but installations must meet the relevant scheme, certification and export-metering requirements. Check with the chosen SEG provider if export income forms part of your buying decision.
Do plug-in solar panels need planning permission?
It depends on the property and installation. Planning considerations can be different for houses, flats, listed buildings, conservation areas and unusual mounting arrangements. Landlord or freeholder consent is also separate from planning permission.
Can plug-in solar power a whole house?
Normally not. Plug-in solar is designed to reduce the amount of electricity purchased from the grid, rather than provide the much larger electricity output available from a full rooftop solar installation.
Are plug-in solar panels worth buying?
They can be particularly attractive for renters, flat residents, households without suitable roof space and people wanting a relatively inexpensive entry into solar. Homeowners with a suitable roof should also compare the cost and likely return with a conventional rooftop installation.
