Understanding Solar Panel Size in Kenya
When people talk about solar panel size in Kenya, they mean both the physical dimensions and the power output (watts). The size you choose decides how much electricity your system can produce. A bigger panel produces more power but also costs more and takes more roof space.
For example:
-
A 50W solar panel is small and easy to install, often used for lighting.
-
A 300W panel is medium-sized and can run TVs, fridges, or small machines.
-
A 550W panel is large, powerful, and best for businesses or big homes.
Types of Solar Panels by Size
