1. How do I know that I’m actually using the electric that I’ve generated and not the electric generated from the Grid?

The Inverter monitors the voltage of the electric at the Grid and will automatically adjust the voltage from the panels so that the panels are kicking out 3 volts more than the Grid. When you request electricity e.g. turning on a light, it will always seek out the highest voltage hence it will use what has been generated by the panels first.

2. What happens in a power cut?

In the event of any disruption to the supply from the Grid the inverter will automatically cut the power from the panels within 0.3 of a second. This is a legal requirement due to Health & Safety requirements. Once the power is restored the Inverter will reset itself again and the panels will start producing electric once again.

3. What happens if I use all of the electric generated by the panels?

Once the electricity generated from the panels has been used then the power demand will automatically be serviced via the Grid. This is a seamless process and you will not notice it. There will be no loss of, or surge in power and there will be no flickering.

4. How do I know that the system is working?

Check the reading on the Ofgem Meter every week. The Ofgem Meter tells you what the Power Company owes you and the main Electric (Import) Meter tells you what you owe to the Power Company.

5. Does my system generate electricity at night?

No. The system is operated by daylight and so therefore does not generate any electricity during night time.

6. Does my system need any maintenance?

No. Once installed the system will operate without the need for any annual maintenance. But for peace of mind you could get an electrician to give it a once over every couple of years but it’s not a condition of the guarantee to do so.

7. Does it cut my carbon footprint?

Solar electricity is a green renewable energy source and so doesn’t release any harmful carbon dioxide or other pollutants. A typical home PV system could save around 1200kg of carbon dioxide per year – that’s around 30 tonnes over its lifetime.
