Introducing the Apollo GEM Generated Energy Management system

Micro-generation systems are at their most efficient when all of the energy produced is used at the point of generation, i.e. within the household where the generator is sited. This results in the minimum possible use of imported energy.

There are many systems on the market which monitor your generation system and allow you to see how much energy is being generated and how much is being used at any given time but getting savings from these systems relies on you to adjust demand to match supply. Since generated energy (supply) and demand change minute by minute throughout the day achieving the balance is near impossible and completely impossible when you are not at home.

GEM is a product that continuously monitors energy supply from your generation system and household energy demand and automatically, second-by-second, adjusts demand to balance supply.

The way GEM does this is by storing excess generated energy which is not required by the household appliances as heat in the hot water cylinder rather than allowing it to be exported to the grid. 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.

GEM can also divert micro generated excess power to other household appliances by using it's threshold mode operation where the appliance is fully turned on when sufficient export power is available.

Most micro-generation systems often produce more power than can be used directly in the household with the result that the surplus is exported to the electricity distribution network. The current FITs scheme for systems under 30KW assumes that 50% of all power generated is exported to the grid. During the summer months PV installations in households which are unoccupied during the day could be exporting 90% or more of the energy generated. GEM automatically uses any surplus energy available to heat your hot water instead of exporting it. This means you don't have to pay to import power later for water heating, and with hot water heating costs amounting to 25% of some household energy bills that's a big potential saving.

Even more good news is that because export energy is not metered but assumed to be 50% of all energy generated you still continue to get the export tariff on half of all units generated by your system even if GEM ensures that no energy is actually exported!

What's more, the lower the FITs rate that applies to your system the higher the savings as a proportion of the system income.

GEM can be simply retro fitted to existing solar PV installations as well as installed with new PV installations.
