Solar photovoltaic (PV) panels allow homeowners to harness the sun’s energy to produce electricity. By generating power on site you reduce your reliance on grid‑supplied electricity, cut your energy bills and lower your carbon footprint.
Consumer Rights notes that PV systems consist of photovoltaic cells (usually silicon‑based), a mounting frame and an inverter. Sunlight strikes the PV cells, creating direct current (DC) electricity which is converted by the inverter into alternating current (AC) for household use. Energy can be used immediately or stored in battery systems for later use. Once installed, PV systems operate quietly with minimal maintenance.
Solar PV installations typically take one to three days. Because there are few moving parts, panels have a long service life—usually 25–30 years. Your roof should be in good condition before fitting panels; installers will assess this during the survey.
As well as saving money, generating your own electricity reduces your carbon emissions. When paired with air source heat pumps or electric vehicles, PV panels can provide free renewable power for heating or transport. Under certain circumstances excess electricity can be sold back to the grid through smart export tariffs.
Solar PV may be available under ECO4 as part of a package of energy upgrades—particularly when combined with heat pumps or high‑retention storage heaters. GBIS and other regional grants may also contribute to the cost. Visit our Measures page to see how solar PV fits into a whole‑house retrofit strategy and check our GBIS page to learn about insulation support.
