Hard on the heels of the best March ever we have the best April ever, well since install in April 2010. Previous best was March 2011 at 484kWh.  Didn't think it was going to happen with the changeable weather the last couple of days but Clears skies this morning and a nice cold south westerly gave 18kWh before it clouded over.

 161.8 kwh/kwp

Best April ever and only been beaten 3 times in 9yrs in May/June/July 2018

Wish we could keep this low pollution enviroment. Hope it shows people how good it could be. It will bring some changes no doubt but probably not enough.
