On Osiyeza I need lightweight and reliable systems.
I chose the Solbian Super Rugged(SR) series of solar panels which are flexible lightweight panels, are completely waterproof and resistant to salt water. The Merlin technology monocrystalline cells have a cell efficiency of 21% which is very high compared to others. Being super rugged means they can handle me walking on them which is important should I ever need to do any rudder repairs.
The fore and aft pairs use separate charge controllers (redundancy/backup) giving a total of 516 watts. The weight of all the panels is only 7kg.
Why are there only panels on the starboard side of the cabin?
The solar system was designed by Dr Christiaan Oosthizen from Tshwane University of Technology. He studied the last 20 years of weather and solar data along my predicted route and then used some very clever mathematical algorithms to predict how much solar radiation I should get. It also indicated that overall the starboard side would receive up to 10% more than the port side.
