The Alpha Solar collector has a unique CPC reflector that maximises the surface area which receives the sun's rays. The CPC reflector acts like a giant mirror that reflects all of the sun's rays and light into the entire diameter of the heating tubes. This means that less tubes are required and so the unit is smaller, more powerful and more discreet on your roof. The Alpha collector is up to 41% smaller than other evacuated tube collectors on the market.
The unique CPC reflector ensures that the sun's rays can reach 360 degress of each tube's surface area. Even on a dull day your Alpha Solar collector works hard saving you money.
Alpha collectors are manufactured using the latest European technology available and are constructed using a high quality anodised aluminium frame. This ensures that the collectors resist corrosion especially when used near the sea.
The tubes are frost tolerant and have passed the AS/NZ 2712 2007 Standards Freeze Test to -15 degress Celcius without the need for frost protection or Glycol. Alpha Solar has passed the ice ball test for hailstones 25mm in diameter.
Because the Alpha Solar collectors are more powerful they are smaller and require up to 40% less tubes to create heat. Less tubes means lower maintenance and less cost involved in replacing tubes that might be accidentally broken.
Each tube in the collector consists of two layers of borosilicate glass with a vacuum layer between them. The vacuum acts like a thermos flask, retaining up to 97% of the thermal energy, resulting in an increased efficiency.
The unique CPC reflector ensures that the sun's UV rays are fully reflected into the 47mm internal glass tubes. The tubes are coated with a highly efficient composition called CERMET which absorbs, stores and transfers heat. An aluminium fin within the tube transfers the heat into the copper U pipes that carry the heated water to your hot water cylinder.
