PV Panels - Update

Well, it's nearly two months since our six PV panels were installed. In that time we've generated 247 units (kWh) of electricity. This is about twice to three times the amount of electricity that we've used.
At the moment we're generating about 3 - 4 units per day. In early July, when it was very sunny and days were long, we were generating up to 6 units per day. However, on a few dull and rainy days we only managed to generate 1 unit.
