Why Solar?

Save $$ on Energy Costs. Solar Panels can reduce the amount of electricity or gas used for water heating by around 75% per annum, therefore considerably reducing your monthly energy bills.

PV vs Thermal

What is the difference?

Solar PV (photo voltaic) panels convert sunlight into electricity, which is stored in batteries. Solar thermal converts sunlight into heat, which is used to produce hot water. Given that the average household used around 15kWh/day just to provide hot water, using Solar Thermal can greatly reduce total household electricity usage.

Why choose Solar Thermal?

PV and Thermal can work side by side, however in terms of $/Watt, Solar Thermal is only about 20-25% the cost of PV, due mainly to the fact that the performance is so much higher. While PV panels average around 13-15% conversion.

How It Works

Heat Absorption and Storage

Solar Panels are normally connected to a hot water storage tank, either directly or via a heat exchanger when an anti-freeze liquid is used.

The operation is very simple:

1- Evacuated tubes convert sunlight into usable heat

2- Heat pipes transfer heat rapidly to header pipe

3- Water is pumped through header pipe, absorbing heat

4- Heated water returns to storage tank/heat exchanger

No Sun?

Even in poor weather you are guaranteed hot water, as the hot water system still has gas or electric boosting.

Domestic

Solar Panels are ideal for domestic hot water and space heating applications. They can be installed on almost any roof type and even on walls. Solar Panels have been designed with aesthetics in mind, so they will actually become a proud feature of your house!
