Do solar panels increase home value? What the actual data shows
The largest UK study found a 6.1% to 7.1% sale price premium. Here is the full picture.
Read the guide →Adding a battery to solar panels you already own
Retrofitting a battery to working solar is straightforward. The paperwork is where people trip up.
Read the guide →Charging an EV from your own solar
Every surplus kWh is 3.6 to 5 miles. Whether that beats a 7p overnight rate is arithmetic.

It moves heat rather than making it. The cycle, the efficiency numbers and the trade-offs.
Read the guide →Why tariff choice moves payback more than kit choice
Identical kit, five times the export income. The tariff decision worked through with August 2026 rates.
