How much do solar panels cost in Kenya?
A 100W panel typically sells for about KSh 3,400, a 300W panel for about KSh 7,500 and a 550W panel for about KSh 11,700, going by the median of the listings we checked. The ranges are wide because the same wattage is sold by marketplace sellers under little-known brands and by solar shops stocking big-name modules, which cost more.
Per watt, larger panels are cheaper: about KSh 21 a watt for a 550W panel against about KSh 34 a watt for a 100W one. For a house or a business, a few large panels usually beat many small ones, as long as your roof and installer can handle them.
Why some panels are suspiciously cheap
Kenyan marketplaces carry many panels with stated wattages they cannot deliver. Watch for:
- Impossible sizes. Single panels listed as 715W to 1000W at around KSh 10,000. No standard single module of that power exists at that price; we leave these listings out of our figures.
- A tiny panel for its wattage. A real 300W panel is roughly 1.6 metres long. If it is much smaller, the rating is not real.
- No datasheet. A genuine panel comes with a datasheet and a label on the back showing its maximum power, voltage and current, measured under standard test conditions.
- Huge "discounts". Many listings show a crossed-out price several times the sale price. Judge the sale price against the table above, not against the crossed-out one.
A panel that gives half its stated power will not charge your batteries, and the inverter and batteries you bought with it end up working harder than they should.
Mono, poly or bifacial: does it change the price?
Almost all panels sold in Kenya today are monocrystalline, the efficient black panels. Polycrystalline (blue) panels are now rare. Bifacial panels, which also collect light reflected onto their backs, sit at the top of the price range and pay off mostly on ground mounts and carports.
Big-name brands such as Jinko, JA, Longi, Trina and Canadian Solar cost more than marketplace brands, but come with a verifiable datasheet and a long performance warranty. See types of solar panels for the differences.
From panel price to installed price
Panels are only part of a system. A home system also needs an inverter, batteries if you want power at night, a charge controller (often built into the inverter), mounting, cabling, protection and labour. Panels are often less than a third of the total.
For a figure you can budget with, see solar system prices and solar installation cost, or send one request and compare 3 quotes from licensed installers.
Where to buy solar panels in Kenya
You can buy panels on Jumia and Jiji, from solar shops in Nairobi (many around River Road and Industrial Area), or through an installer. Buying through a licensed installer usually costs a little more per panel, but you get panels matched to your inverter and batteries, a proper installation and someone to call if something goes wrong.
