Boiling a kettle for 10 hours

The controller keeps a record of how much power has been generated.

I installed a solar power system while in the UK but I didn’t bother connecting up the solar panel until I got to Spain where our local star actually makes an appearance. This is the system:

The charge controller and breakers. The bare wire on the right is where I have connected the relay to the 12V supply.

Since 7th December 2019 the system has generated 25kWh of power. A standard electric kettle is rated between 2 and 3 kW. Taking 2.5kW as an average:

 25kWh/2.5kW = 10h

Therefore the amount of generated power is equivalent to a kettle boiling water for 10 hours. Not bad!
