Solar Panel Latest
The only thing I don't like about my solar hot water system is there is no remote readout of the temperature of the water in the tank. We don't have a proper loft ladder, so going up to check the temperature is a real faff - until this weekend when I taped a webcam with a 5m USB extension lead to the LED. Now I can read it on my laptop from the top of the stairs.
