When the in house usage decreases even if only by a few watts solarimmersion will automatically increase the power to the immersion heater to use all the available surplus rather than the excess going back to the grid.
Pv solar panels immersion heater.
It also requires a solar compatible hot water tank.
Gem works with wind generation systems too.
This would work better as the load would vary with voltage and the voltage would vary with the amount of sunlight.
In summary i ve never regretted getting the solar pv panels installed and feel very lucky that we found stuart to do the installation.
Gem will work with any solar pv system and uses a standard immersion heater to produce free hot water.
Immersion heaters powered by solar pv solar pv panels produce electricity from the sun.
Hot water from solar pv panels an obvious choice many households prefer not to export their surplus electricity to the grid.
A solar thermal system is another way of heating water with solar energy but is a separate technology and process to that of solar pv panels.
This proportional control technology makes the solarimmersion a highly efficient solar energy manager.
In ireland there is no payment for exported power and it is simple and easy to use this surplus to provide solar hot water.
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.
The system is simple to install and will not affect your feed in tariff payments if you have them.

These panels can be coupled with the immersion heater on the hot water tank to produce free hot water using a device known as a power diverter or solar pv optimiser.
