Was in the streets of Nairobi last weekend and there many shops stocking solar PV equipment and you can buy off the shelf.
The idea to use solar PV to generate electricity in this building came already late. The orientation and slope of the roof are not suitable. The architecture and the generate electricity with PV with the grid tied system is superb. Can’t alter the building now but something can be done on the PV array may be. If there is suitable space somewhere the PV array could be relocated. Let me know your ideas.
