BETTER THAN MONEY IN THE BANK!

We are converting one Guernsey home a week to solar generation, helping our customers offset high rate electricity and selling their surplus to the electricity company.

Calculations show that money invested in Solar Photovoltaic Panels will create a better return on investment than money left in a savings account.

ELECTRIC SOLAR PANELS

sales images

Solar Photovoltaic panels (PVs for short) generate electricity whenever there is daylight. They operate when its cloudy as well as sunny and can offset anything from 10% to 110% or more of your electricity bill.

They do this by connecting to the Guernsey Electricity grid from the road into your meter and consumer unit via a special conversion box called an 'inverter'. These inverters are designed for maximum efficiency energy conversion and are approved by the local electricity company.

Solar energy production is now a world-wide phenomena and has been available in Guernsey from E-Si Limited for many years. Did you know we installed the first grid-connected solar system in Guernsey in 2003? And did you know Germany produced more than 50% of its entire electricity by solar photovoltaics last summer for the first time?

Are you asking yourself:

"Will I still be able to afford my fuel bills in 10 years time?"

AVALON, THE COMPLETE ENERGY SOLUTION.

  • Avalon is a project E-Si have recently completed. We were responsible for the design and installation of a Mitsubishi Air Source Heat Pump, a Heat Kube, 300L HW Tank, Dataterm Heating Controls and 3.29kW of Solar Photovoltaics.

  • Avalon has the complete energy solution, a holistic upgrade more efficient than any other energy technology solution, a model all houses should follow.

    The Air Source Heat Pump uses solar energy in the air to heat your radiators and hot water using a small amount of electricity to enable the conversion. This means the on-site solar cells (PVs) power the heating reducing heating bills.


  • The inverter for the Solar PVs comes with internet connectivity built in so you can monitor each panel and the systems overall performance. This provides users and installers with real-time detailed information to ensure that the solar system performance is optimized over the life of the installation.
