Ok, the sun is still in the sky, but its late enough that I am going to declare November over now, and blog about my generation from my solar farm. First here is the exciting main chart thing:
So thats 34.2 MWh, or to put it in rooftop-solar or home-energy terms, 34,248kwh of lovely renewable green solar power! Not bad I think for a pretty wet, cloudy November in the UK. June in the Sahara desert would be different…
A crude extrapolation to 12 month would give 410MWh which is obviously way too low. I am expecting more like 1,000-1,200 MWh for the whole year. If I can get 1,200 that would be nice, and I would not worry too much about the business case for the whole thing. However that depends on the ongoing costs. I am still comparing quotes and discussing ways to cut that. The actual annual sums for each individual component always seem reasonable, until you multiply them by 25 years…
I do have some other software that analyses the output and gives an estimate of how good or bad you generation has been. That software suggests that November output for me has been noticeably better than expected, but you shouldn’t get too excited extrapolating from a single data point. Lets not forget the panels are new(ish) and clean(ish), and that will not always be the case. The real reckoning will come after a full years generation and operations.
In other news, I got paid! So its only for part of October (we had some downtime, and also did not switch on until the 4th) but the money turned up in my account on time and the right amount, which is never something a small business can take for granted. If you are a UK residential electricity customer of OVO, then I am providing some of your power :D. I get paid for the power plus VAT (sales tax in UK of 20%) so I have to pay that tax to the government (useless busywork!). It definitely feels good to have even just this ONE entry in the company accounts that is green instead of red!
