2020 generated 3,740 kWhrs (104% of 3,583kWhrs)

The table below compares the monthly generation against the PV-GIS predicted output. Red figures are below predicted level and green figures are above.

This year started very wet with Jan and Mar below expectation, and then a sunny summer total generation ended up at 3,740kWh. The best years generation so far.
A total of 2,415kWh's were imported this year, approx 1,000 kWhs down on last year due to lock down and not using car for 3 months.
By 12th April 2020 we had generated as much as imported this year almost 2 months earlier than last year. Also gas usage data graph below, gas usage in 2020 was 3,094kWhs less than 2019 total.

2020 Stats:

Total generation in 2020 = 3,740 kWh's
