Sharp

The Sharp range of panels offer a good range of wattage for your pound, they are made to a good standard, which we feel gives a good return on your investment. They are good to look at and offer a product from a company that has been in the UK mindset for many years, whom we feel will give long term support and warranty should it be required. Sharp have also launched an all black module, the data sheet can be downloaded below.

Sanyo

The Sanyo HIT Range of Panels are a very good overall performer, however these are probably one of the more expensive products on the market at present. We supply these if the customer requires them, but they will affect your payback time due to costs. These are however smaller in size than many other manufacturers, and therefore on some size specific installations these could be beneficial. These panels have some of the best Kw returns of any panel on the market.

EDDI Units Supplied and Installed

We are also an authorised supplier and installer of the EDDI made by Myenergi a Lincolnshire based manufacturer.
This unit proportionally sends surplus energy to your immersion heater from your solar PV plant. If your out or not using your energy from your PV plant, this monitors what you are using in your home and sends the power to your immersion heater, saving further money on your home energy needs.

You will need to already have a dedicated circuit for your immersion heater, and a suitable immersion heater installed in your tank to benefit from this.

The unit can proportionally control upto 2 circuits and also be used as a timer.
