A question we always get asked is “Are Solar Panels & Energy Storage going to cut my electricity bill?” The answer is yes!!!
We have supplied & installed many Solar PV systems over the last 7 years & have been installing energy storage as part of new installations or retrofit to existing systems for the last 2 years.
Using one of our clients as a case study we can see the benefits in a very short space of time. In December 2016 we installed a new 5.23kWp SunPower system using 16 x E20 327w Panels with SolarEdge Inverter & Optimisation as well as a Tesla Powerwall 1.
The client has so far in 2017 provided 41% of their electricity consumption from Solar, in March it was 66% & April has started well at 91%.
The East facing SunPower panels generate electricity as soon as the sun rises & often by lunchtime the Tesla Powerwall is at 100% stored capacity leaving the house to be powered by sunshine until sunset when the battery takes over.
Commenting on the system our client says:
“It’s easy to live with and the app is fascinating. We have just come off a single period of 46hours where all the power we consumed came off our own roof.
Really looking forward to May, June and July when we think we are going to be strong net producers of power.
Next steps? We are thinking of maybe more one day. The back of the house is an option due to the East West nature of the house and very long periods of the day we would have both sides in full sun. Maybe a second battery? We think if we did that we would almost be able to change our oil fired boiler for an electric one in a few years when it needs replacing. Ground source? What about when all our cars are electric?”
