SOLAR ELECTRICITY

At night...there is not any electricity generated by solar panels. Batteries must be used if solar the sole source of energy. However, batteries are heavy...bulky...and...subject to a myriad of problems and maintenance hazards. Hence...in the sub-Saharan part of Africa...abundant sunlight is worthless when the sun goes down. It can be so dark one can't see the hand in front of face. No sun...no light...no energy...no nothing but camp fire and bug-riddled tent,(WSJ A-15;11-13-17).
