Here's the graph for July's generation from our array of solar panels. This is for our 2kW 8 panel solar array (Panasonic HIT panels), mounted on our south-facing roof at approximately 35-40° angle from the horizontal.
The dark blue line is July - the light orange line is December by way of comparison. At a total of 288.6kWh for the month, that's 80.86kWh higher than the forecast.
Here is July included on the yearly chart (and a bit of August too....)
July is the highest month of generation of the year. August isn't complete yet, but I'm betting it will be slightly lower than July looking at the forecast.
Here's the annual sun-strength chart. The value for August is based on the first 12 days of the month, so isn't completely accurate:
The shape of the curve is more obvious now - a steep climb from January to April, and a more gradual decline in sun strength from July down to December. The strange blip in May (as discussed on last month's post) is now very clear.
The total forecast for the year that we were given by the installers was 1645kWh. As of last night (12th August) the total for the year stood at 1754kWh, with 19 more days of August to go to complete the year. I reckon the final total is going to be between 1850 and 1900kWh, depending on how many sunny days we get between now and the end of the month.
Next month I'm going to do a wrap up of the whole year, with financial predictions for the 20 year life span of the panels.
