ABSTRACT
The 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller. These were assembled together with necessary protective gadgets like cut out switches; to give the 200W expected. The solar panel was mounted outside the building to allow for maximum collection of sun energy. It is expected that the system will help the department meet up with its office duties even when central power is not available.
