Sunny Cold April Best Solar Panel Generation - Maximum Electricity Output from PV Solar Panels

One bonus of the cold weather we have experienced in the UK recently is that the cold improves the generation from solar panels by increasing their efficiency. Today has been a perfect example, a very sunny day but with below average temperatures of around 8C.

The net outcome has been the best ever electricity generation from our solar PV panels. Temperature does make a massive difference and a cold sunny day like today has generated more electricity than any day in 2012 which is pretty incredible when we are still 2 months away from the longest day.

Just imagine how much solar electricity you could generate from a very cold sunny day in June when the sun is above the horizon for so much more of the day.

The electricity generated today was 21.4kWh which is the first time our solar panels have breached the 21kWh level. In 2012 we had a few days that hit 20.5kWh but clearly the effect of temperature on the solar panel performance has outweighed the effect of the longer days in June and July.

The electricity generated per kWp of panels works out at over 7kWh per kWp which is quite an impressive performance and obviously is improved by our location and orientation of SSW facing solar panels.
