Installing a solar system will protect your home from rising electricity costs and produce a positive annual return on investment.

Solar electricity is one of the cleanest forms of energy available today. By purchasing and using solar power you are combating global warming and are helping keep New Zealand clean and green for this generation and the next.

An proper insulated house, double glazing, and heating with solar energy will give you the opportunity to chuck out the old electric heater! You don't even have to heat additionally. There are great concepts for low energy houses, that work great. And you don't use any power for heating. Even in winter you can use solar power! It is an investment, but on the long run it counts, because electricity and energy will be more and more expensive in the future!!!!!
