Why Solar PV

How solar and a battery work, from morning to midnight

Solar panels turn daylight into electricity for your home. A battery keeps what the roof makes during the day for the evening, when most homes use the most.

  • Day. The panels power the house, and the surplus fills the battery before anything is exported.
  • Evening. The battery runs the house instead of buying from the grid at peak prices.
  • Overnight. On a time of use tariff, the battery can top up at the cheaper overnight rate.

How does solar work?

Photovoltaic cells turn daylight into electricity. Panels still generate on cloudy UK days, because they use light, not heat.

Why should I get solar PV?

It cuts the electricity you buy from the day it is switched on and gives you some protection from future price rises. How much depends on your roof, usage and tariff, so we give you a figure for your own home at survey.

When should I get solar?

As soon as you are ready. The savings start the day the system is switched on.

Benefits

Why go solar

Lower energy bills

Generate your own electricity and reduce what you buy from the grid each month. How much depends on your roof, your usage and your tariff.

25 year system lifespan

Panels are built to keep generating for decades, so what you make on the roof is electricity you are not buying.

Cut your carbon

Power your home with clean, renewable energy and shrink your household carbon footprint.

Add value to your home

Buyers are attracted to lower running costs and a better EPC rating.

Battery storage ready

Store power generated by day and use it at night. Charging overnight at a lower rate and using it at peak times is only possible if you are on a flexible electricity tariff with time of use pricing.*

Earn from what you export

Get paid for surplus electricity you send back to the grid. Shop around utility companies for the best export rates.

What you get in writing

The guarantee, the warranties and the paperwork.

Two year workmanship warranty

Our workmanship on every solar, battery and heat pump installation is covered by a two year insurance backed workmanship warranty through Bluedrop Services, underwritten by Financial & Legal Insurance Company Ltd. The equipment itself carries its own manufacturer guarantee, and the term for each item is stated on your quote. It holds even if the installer did not, and it transfers to the next owner if you sell.

Manufacturer warranties

Aiko panels carry up to a 30 year performance warranty and a 15 year product warranty. The Sigenergy SigenStor, Fox ESS inverters and batteries and the Tesla Powerwall 3 carry ten year warranties. Every term is stated on your quote, per component.

The certificates

An electrical installation certificate under BS 7671, the G98 or G99 acknowledgement from the network operator, and the guarantee certificate, all in your handover pack within seven days.

Often done together

Cut what the house uses, then make your own.

Measures planned together cost less in surveys, access and disruption, and work better once they are in.

FAQs

Solar questions, answered

Does solar really work in the UK?

Yes, better than most people expect. Panels run on daylight rather than direct sunshine, so they keep generating under cloud, just at a lower output, and long summer days make up for a lot.

Are there still grants available?

Possibly. The Warm Homes Plan funds upgrades for eligible lower income households through council run schemes, so ask us or your council. If you do not qualify, solar panels and batteries on homes are zero rated for VAT until 31 March 2027. Our Warm Homes grants guide has the detail.

How many panels can fit on my roof?

We use an online platform to locate your house and see provisionally how many panels will fit, then we confirm it in person at the survey, measuring the roof and checking shading and structure.

How much does it all cost?

It depends on the number of panels, the size of the battery and inverter, and the manufacturers of the components. Prices start from £3,000. See what solar panels cost for typical ranges and a worked payback.

Do I need a battery?

Most solar systems benefit from a battery to store energy generated but not used straight away. A battery can also charge overnight and run the house at peak times, but only on a time of use tariff. Not every home benefits financially, and we check that at the survey. Battery storage explained.

What’s the return on investment?

Typical payback is from 4 years onwards, depending on the size of the system, orientation and shading, how much of the electricity you use yourself, the cost of the system and your tariff. These are estimates; your surveyor will give you a figure for your own property.*

Is my roof suitable for solar?

South facing roofs give the most output, but east and west facing roofs still perform well. At your free survey we check orientation, pitch, shading and structure, then design a system to suit.

Do I need planning permission?

For most houses in England, no. Roof panels are usually permitted development as long as they do not stand more than 200 mm proud of the roof slope or rise above the highest part of the roof. Listed buildings need consent, and conservation areas and flats can have extra rules, so we check at the survey.

What types of panels work best?

Monocrystalline panels are the best overall choice for homes: the highest efficiency, a long lifespan and good performance in low light, which matters in the UK. We fit Aiko panels as standard.

How long do solar panels last?

The panels we fit carry a manufacturer performance warranty of 25 years or more, and typically keep generating beyond it with a gradual loss of efficiency. The exact warranty for your panels is stated on your quote.

Should I choose in roof or on roof panels?

In roof panels replace some of the tiles and sit flush, which many people prefer the look of. On roof panels sit above the tiles on rails and suit most existing roofs. If the roof is being replaced anyway, in roof is worth a look. See our in roof case study.

Can I sell energy back to the grid?

Yes, through an export tariff. The company paying you does not have to be your current energy supplier, so you can shop around. Our guide compares solar export rates.

Do solar panels add value to my property?

Solar can make a property more attractive to buyers through lower running costs and a better EPC rating. Any effect on the sale price depends on the property, the system and the local market, so we do not put a figure on it.
