Over the last week or two we have been all conscious how much warmer it has been as compared to the long dark days of January. The spring flowers are also feeling the warmer weather coming as the daffodils and crocuses come into bloom. In our garden the daffodils are about two weeks later than last year.
Those of us with solar hot water panels will also have been noticing the difference. We have now started having days when the panel alone can provide all the hot water we want.
At Northfield Ecocentre we record the performance of the panel. The graph in the picture above is updated to yesterday but clearly shows the rise in output. It shows the amount of daily heat produced by the sun on our panel expressed in Kilowatts. The way it dramatically increases in the summer can clearly be seen on the graph which started last spring.
If you want to watch how it performs during the summer it is regularly updated and can be seen here.
