Reliable solar net metering solution from Chatham House

No More Electricity bills when you have Chatham SolarPlus.

Affluent and responsible societies worldwide are moving away from expensive, environmentally hazardous power sources, towards sustainable energy sources which are cheaper, more environmentally friendly and beneficial for the survival of future generations.
Hence, there is a significant growth in societies switching to solar energy as an alternative to electricity.

Making an investment in solar energy is easy. There are a multitude of suppliers who will claim superiority over others in offering you the most economical and most effective solution.

However, one must be cautious when selecting the right service provider since switching to solar energy is a lifetime investment, and once taken would be difficult to change. Hence, more than the lowest price, the deciding factor should be; service providers reputation, the brand names of the components used, warranties, and most importantly; the continuation of business of the selected service provider (they must be in business at least for a few generations)

Our Vision

To provide turnkey business solutions in the sector of solar energy; and be at the forefront in initiatives to protect our environment by providing sources of renewable energy

Make the switch to solar in 3 easy steps
