Our company moved into our new offices this week, and the frist thing we did was of course to cut the wire to the power grid and put up our own system. The panels were mounted on top of the building today, and we are now probably one of very few self-powered solar energy companies. The tech details: Our electricity demand is covered by two 100 W panels, a 12 V battery pack of 150 Ah and a 1 kW inverter (a bit too big that one..). It is so pleasing to be able to demonstrate to customers in Malawi that solar-powered business is within reach. The price of the system we have installed, including all electrical installation work, components, lights, switches and all, will be just above 500,000 Malawian kwacha (about 7,700 NOK, or 900 €). Not too bad for powering the office with solar energy every day, without ever having to think about electricity bills connection fees.
