Description

The Apollo GEM Solar PV optimiser ensures that the maximum amount of electricity, generated by the Solar PV system, is used within the household. It directs surplus electricity that is being generated by your Solar PV system but not used in the house, into the immersion tank. This allows you to efficiently use the electricity that would otherwise be exported.

The Apollo GEM is also available in GEM-D, a wired version.

Under the solar PV feed-in tariff, you are paid 4.64p for every kWh of electricity you export back to the electricity grid. If you were to buy a kWh from your electricity supplier, you can expect to pay in the region of 15p / kWh. Therefore, in an ideal world you want to use all the electricity that you produce from the solar PV panels in the home instead of exporting it back to the grid.

We all know much it saves, but how does the Apollo GEM work?

By constantly monitoring the energy supply from your Solar PV system, along with the electrical demand of the household, the Apollo GEM is able to divert surplus electricity to your hot water tank or storage heater that would otherwise be exported back to the grid. The GEM constantly keeps the amount of exported energy as close to zero as possible, but makes sure that no extra electricity is required to be imported to run household appliances.

The Apollo GEM is able to precisely alter the level of electricity diverted to the immersion or storage heater, meaning that even tiny amounts of surplus electricity can be used efficiently. This makes the Apollo GEM suitable for Solar PV systems of 500Wp to 4KWp during both the winter and summer.

In most cases, micro-generation systems can produce more power than the average household demand. This is shown by the current Feed-in-Tariff assuming that 50% of generated power is exported – based on a <30KW system. However, because exported energy is not metered, you continue to get paid even if you are using every last Watt of generated electricity.

The Apollo GEM also doubles up as an immersion timer, giving you temperature and timing controls for when the water is being heated through surplus or imported electricity.

Not only can the Apollo GEM be installed linking to your Solar PV system, but any home micro-generation method.

    An excellent addition to a solar PV system. The electricity it uses really is “free” it took me while to figure that out. The control unit also gives a quick and easy immediate evaluation of your system performance – importing and how much – exporting and how much – heating water and how much power is being used, can control 50 watts to 3500 watts to the immersion element – amount of power “saved” by using the Gem on a monthly and daily basis. We have a 2700 watt immersion, after using 50 litres of hot water in the washing machine, this can return the tank to 60 deg C in less than 2 hours. We have not used our gas boiler to heat the hot water since the end of April.

    Excellent product, extremely clever if you have pv and a still have a hot water cylinder you must definately get one of these terrific devices..we have have reduced our domestic gas use for hot water by about 70-80% of the year..need I say more..!
