However you may not be aware that there is a gadget which enables you to keep this surplus energy use it to power your immersion heater reduce your electricity bills even further and still.
Solar panel immersion heater.
Temperature control panels can be placed within the tanks that control the water heater to ensure a consistent heat.
My assumption however is that when the pv array is not generating enough power mains electricity would be used to get the water in the tank up to the desired temp as per the thermostat.
The 100w panel will be to supply the 8000w lf pure power sine wave inverter with this and a charge controller surely i would be able to make the 2 8kw required to heat my immersion heater.
We have solar panels and a power diverter and i understand how excess generated power from the pv array is used to power the immersion heater in the tank.
See the link for the type i am thinking of using this alone with a 24v supply can generate the 2 8kw required.
By using this easy to build solar stock tank you probably won t need an electric tank heater to keep your livestock waterer from freezing this winter.
Solar pv panels will often produce more energy than you can use in a day and without a solar battery your surplus will be sent to the national grid.
Modulation based solar pv surplus energy manager that monitors in house usage and pv power production to divert almost all the available surplus power to the immersion heater to heat water.
