Solar Photovoltaic (PV)
Solar PV (photovoltaic) panels turn sunlight into electricity using special cells. When sunlight hits these cells, it creates a flow of electricity. This electricity is direct current (DC), which is then converted into alternating current (AC) by an inverter, making it suitable for home use.
Most PV systems have panels that fit on your roof. An inverter is usually installed in the loft, along with a generation meter. Any surplus electricity is sent back to the national grid. If you have a heat pump, surplus solar electricity can be used to heat your water, helping to lower your electricity bills.
The term photovoltaics (or PV) comes from the process of changing light (photons) into electricity (voltage), called the photovoltaic effect.
Maintenance
If we have fitted solar PV panels on your home, Platform will monitor the system remotely. If a problem is detected, they will contact you to arrange a visit from a qualified electrician.
It’s best to allow access for all necessary service visits to ensure the system is working efficiently. You don’t need to agree to any maintenance contracts or pay any fees.
You can also help by checking the system regularly.
The generation meter has a red light that flashes when the panels are generating electricity. The faster it flashes, the more electricity is being produced. At night, the light stays on constantly. If there’s no change in the meter reading over a week, the system might not be working. Report this for repair to the Customer Hub on 0333 200 7304 or via the customer portal.
Benefits
- Free electricity during daylight hours.
- Lower electricity bills.
- Reduced reliance on fossil fuels and lower greenhouse gas emissions.
- Helps combat climate change and reduces air and water pollution.
Maximising Savings
- Use appliances during the day when the panels are generating power.
- Run high-power appliances, like washing machines and dishwashers, one at a time and at lower temperatures.
- Use timers to run appliances while you’re out during the day.
- Cook your evening meal during the day using a slow cooker instead of the hob or oven.

Energy and money-saving tips
- Only boil the amount of water you need in the kettle.
- Cook with lids on pans and use your microwave more often.
- Dry clothes outside or on a clothes airer instead of using a tumble dryer.
- Turn off appliances when not in use and avoid leaving them on standby.
- Switch energy suppliers to get a better tariff rate.
