Solar Power and Bank Holidays

Its August bank holiday weekend and the nation holds it collective breath and prays for sunshine. But the history of this public holiday does not inspire much confidence.

When the holiday was introduced in 1871 it fell on the first Monday of August, when there was a better chance of decent weather. But a few washouts during the 1950s and 1960s persuaded the politicians to shift the Bank Holiday to the last Monday in August. You can understand the desire to make the long Autumn period before Christmas as short as possible, but the weather is always going to be potentially better in early August for a public holiday.

The weather on this Bank Holiday often signals the change from summer to autumn. My output from the PV panels has shown a steady decline each month with average daily KWh falling from 10.6 KWh in June to 8.2 KWh in August. Friday 26th August was our worse day ever with a pitiful 1.55Kwh generated over a dark and rainy start to the holiday weekend.

The Met office are predicting that 2011 will be the coolest summer for 18 years with an "average" temperature in the East Midlands between June 1st and mid August just 15C. Trust me to install PV panels at the worst possible time.

This Christmas I’m asking Santa for selective Global warming over my house.

Enjoy your weekend…..
