Pricing
What it costs,
roughly.
Solar and battery prices depend on your home, your roof and your installer. Here is what a typical setup costs, so you have a realistic starting point before you ask for a quote.
Solar panels
6 to 8 panels, about 3 to 4 kWp
A typical home array. It makes power through the day, and you use or store whatever the house does not need right away.
Typically from
£7,650
Home battery
Around 10 kWh
Stores the energy your panels make, so you can use it in the evening instead of buying it back from the grid at peak prices.
Typically from
£5,100
Smart battery system
Battery plus live price tracking
A battery that trades energy for you. It charges when power is cheap, stores it, and sells the surplus back when prices are high.
Typically from
£6,800

Two homes rarely pay the same. These are the things that push the number up or down.
The size of the system
A system is sized to how much electricity you use. A larger home, a heat pump or an electric car all call for more panels, and more panels cost more.
Your roof
Pitch, orientation, shade and the roofing material all affect how long the work takes and what it costs to mount the panels safely.
Whether you add a battery
Storage adds to the upfront cost, but it lets you use much more of your own power in the evening instead of selling it back cheaply.
Subsidies and tax
Grants, subsidies and tax deductions vary by country and year, and can bring the final price well below the figures above.
Your installer
Quotes for the same job genuinely differ between installers, so it is always worth comparing a few before you decide.
These are typical figures for a home, not a fixed quote. Your final price depends on your roof, your energy use and your installer, and may be lower after subsidies, grants or tax incentives.
