Is My Roof Suitable for Solar Panels? Direction, Tilt, Shade and Strength
Short answer
Most roofs in Kenya can take solar panels if they have unshaded space and a sound structure. Because Kenya is near the equator, panels work well flat or at a gentle tilt of roughly 10 to 15 degrees, facing north or south, so orientation matters less than shade. The installer should check the roof structure, material and available area before designing.
What to check
- Shade: trees, walls, water tanks and neighbouring buildings. Even partial shade can cut output of a whole string.
- Space: a 550 W panel takes roughly 2.5 square metres. Count the area free of obstructions.
- Direction and tilt: near the equator, a gentle tilt helps rain wash the panels; flat roofs use tilted frames.
- Roof material: iron sheets, tiles, concrete and others each need suitable mounting hardware and sealing.
- Structure: rafters and purlins must carry the load and wind uplift.
- Condition: an old or leaking roof should be repaired first.
- Access: safe access for installation and cleaning.
No suitable roof?
Panels can go on a ground-mounted frame, a carport, a pergola or a pole mount if you have open land. A site survey will recommend the best option.
Wind and safety
Mounting must resist wind and keep roof penetrations watertight. Cable routes should be protected, and the array earthed and fitted with proper isolation. Our solar installation starts with a roof and site survey.
Common questions
Do panels have to face a certain direction in Kenya?
Not strictly. Near the equator both north and south facing work well; avoid shade and keep a small tilt.
Can panels go on an iron-sheet roof?
Yes, with the correct clamps or rails and weather sealing.
Will panels damage my roof?
A good installation uses sealed fixings and does not damage a sound roof. A weak roof should be repaired first.
