Thanks for your comments.
I have no experience of PV so I am basing my expectation on my experience with evacuated tubes for water/space heating. I have 100 tubes which produce about 7000 kWh per year but produce virtually nothing from mid/late October to early/mid January. November production might be below 5% of what I get in March for example. Should I expect PV to be similarly useless at that time of year or will PV produce something worthwhile despite these overcast conditions? |
