Abstract:

The installation of Photovoltaic (PV) solar systems in institutions as well as homesteads in the rural areas in
Kenya is increasing at a high rate; and so is the need for the stake holders to make sure the PV solar systems are
professionally designed, sized, installed and maintained. In PV solar system installation, the designing, sizing and the
installation are very critical steps. A wrongly designed, sized and installed system will not perform optimally and will
underperform (for undersized systems) and waste energy and resources (for oversized systems). Furthermore,
undersized systems do not perform to the user’s expectation discouraging the user and eventually a negative customer
attitude creeps in which may affect the uptake of solar PV systems. On the other hand, an oversized PV system is extra
expense on the side of the client, creating an exaggerated high cost of PV solar systems, again discouraging potential
clients from the adoption of the technology. Both scenarios mean loss of business, jobs and the economic and social
benefits associated with PV technology. We present a case study of poorly installed PV systemsin Makueni County,
Kenya. We observed that the solar modules specifications at the back of the modules were not clearly done, the
batteries were poorly matched and the cables used in the installation were undersized. Due to these issues, even a
normal television set was not able to work since the system was installed four years ago (in 2012).The above case
emphasizes the need for training in PV solar system design, sizing, installation, and maintenance
