Free hot water and more from solar PV

If you own a solar PV system its is probable that 50% or more of the electricity generated will be exported, that is given away, to the electricity grid.

The Apollo GEM is an innovative solar energy management product that will use all the surplus power generated by your PV system to produce hot water. Every unit of power used to heat the hot water in this way reduces imported energy by the same amount resulting in a significant saving in imported energy costs.

As of April 2019, for new PV installations,  no feed-in tariff payments are made for generation or export and therefore it's more important than ever to "self consume" as much of the on-site generated energy as possible. Currently any energy exported, and that could be half of all the energy your PV system generates, is lost and you will have to pay your standard energy prices to buy it back.

GEM stores as much energy as a typical battery storage system costing 10 times as much!

GEM has now been enhanced to be able to work in two distinct modes to allow connection of any type of appliance in addition to heating appliances, so now excess PV power can be used to power other appliances once your water has been heated saving even more!

GEM will work with any solar PV system and uses a standard immersion heater to produce free hot water. The advanced GEM controller ensures maximum usage of PV power that would have been exported. The system is simple to install and will not affect your feed-in tariff payments if you have them. GEM works with wind generation systems too!

For larger systems GEM can be configured to work with 3-phase installations up to 24KW per phase.
