3.15kWpk      157.0      11.0   50.9        530 kWh      168.25

Surprisingly good June, despite all the overcast weather. 3rd best in 10 years and 5% above my long term average.


"Funny how people aren't as excited to get their stats out this month compared to last month!"

Still only 1st day of the month! so reasonably excited - especially as I have had to provide photographs of the meter reading as this quarters FiT read is way above there seasonal tolerance levels - even I had to go back and double check!

Your kWh/kWp is 80% higher than mine!

That's an improvement, it was only 50% higher last month (194 kWh/kWpk)  Grin.   Helped at this time of year by the shallow panel angle!  Average annual figure is 1161 kWh/kWpk

The desert thing is an urban myth - debunked by the Met Office and others. One definition of a desert is rainfall of less than 10 inches (254mm) per year.  Year to date we have had 211mm and we are only half way through! Most years I record 450 to 600mm.

The real reasons my kWh/kWpk figures are high in the summer are a) the shallow panel angle b) we do get a lot of clear skies due to the fact we are a pennisular sticking out into the channel causing all sorts of weird effects, one is a so called micro climate and c) we get constant cool wind to keep the panel temperature down - currently 25 MPH and 17 deg C
