The system is simple to install and will not affect your feed in tariff payments if you have them.
Pv solar panels immersion heater.
Gem will work with any solar pv system and uses a standard immersion heater to produce free hot water.
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.
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.
The advanced gem controller ensures maximum usage of pv power that would have been exported.
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.
It also requires a solar compatible hot water tank.
Hi experts i am planing to buy a 250 500 watt solar pv panel and connect it directly to my 2kw immersion heater attached to hot water cylinder without any.
This would work better as the load would vary with voltage and the voltage would vary with the amount of sunlight.
Hot water from solar pv panels an obvious choice many households prefer not to export their surplus electricity to the grid.
You could in fact just connect the panels directly to the immersion heater supplying it with dc from the panels.
In summary i ve never regretted getting the solar pv panels installed and feel very lucky that we found stuart to do the installation.
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.
Gem works with wind generation systems too.
