Why Solar Energy ?

We know that relying on coal, oil and natural gas threatens our future with toxic pollution, global climate change and social unrest caused by diminishing fuel supplies. Instead of relying on unsustainable fossil fuels, we must transform our economy and learn to thrive on the planet’s abundant supply of renewable energy.

These are some reasons why you SHOULD opt for Solar Energy.No Monthly Bills to worry about. Solar panels are extremely reliable. There are no moving parts so you don't have to worry about replacing anything. In fact, most people generate electricity for 1000s of hours with little or no maintenance.

Solar energy is environmentally friendly. Compared to fossil fuels which release greenhouses gases, carcinogens and carbon dioxide, solar cells don't release anything into the air. Solar energy is renewable. We never have to worry about running out of sunlight or using it all up. The sun is a consistent power source meaning it's always going to be there every day.Solar technology is constantly improving. Solar installations are increasing by an incredible 50% every year, most of which are small homemade systems. We can design the system to suit your individual needs.

Solar Energy can be connected at any place (remote village, rural, town, island, top of the hill and much more).
