Professional Insulation Contractors in Chelmsford

It depends on how much direct sun your panels get per day and how large your system is. Of course, more shade and smaller systems produce less energy. Your inverter or online system monitoring portal will tell you how much solar energy your system has produced to date.

Unless you are completely off-grid and have a battery storage system, you will continue to receive an electricity bill - even with solar panels. The amount of your bill will depend on how much energy your panels are producing compared to how much energy you are using. Your utility may also charge fixed fees that solar energy cannot offset.

If you have a solar battery system, you can enjoy constant power even in a power cut or outage. However, without a battery, your solar inverter will turn itself off and stop producing power when there is an outage. Some inverter companies offer solar-connected power outlets that may continue to function in an emergency outage.

Solar panels often come with a 20 or 25-year warranty. They produce energy for many decades with only slight performance degradation over time. Some panels may even last for 50 years!

Residential solar installation takes typically around 1-2 days to complete. Commercial installations can take longer depending on the size of the system and the requirements of your site.
