What are the uses of solar energy in Kenya?

Solar energy powers lighting, TVs and fridges in homes, water pumps and irrigation on farms, water heating, street and security lights, and cuts power bills for schools, clinics and businesses. Large solar plants such as Garissa and Malindi also feed the national grid.

What are the disadvantages of solar energy?

The upfront cost of larger systems is high, output falls on cloudy days and stops at night without batteries, and batteries need replacing over time. Fake products and poor installation are the most common causes of problems, so buy from licensed installers.

How do I start a solar business in Kenya?

Decide whether you will sell, install or service, then get the right EPRA licence: a C1 contractor licence needs a Class T3 technician, and V1 or V2 licences need a Class T2 technician. You also need the test instruments EPRA inspects for and reliable suppliers with datasheets and warranties.

Who are the solar energy providers in Kenya?

Hundreds of companies hold EPRA solar licences, from large distributors to small local installers. This directory lists solar companies across Kenya and shows which ones we found on the EPRA register, so you can compare them and request quotes.

When is the next Kenya solar expo?

Solar and energy trade shows are held in Kenya, but dates and venues change each year. Check the organisers' official websites for current dates rather than relying on old listings.

Solar Energy in Kenya: How It Works, Pros, Cons and Uses

How solar power works

There are two main ways to use the sun's energy.

Solar photovoltaic (PV) panels are made of silicon cells. When light hits a cell, it knocks electrons loose and creates a direct current (DC). Panels are wired together, a charge controller manages charging, batteries store energy for the night, and an inverter turns DC into the 240V AC that household appliances use.

Solar thermal uses the sun's heat directly. A solar water heater on the roof heats water in tubes or a flat panel and stores it in an insulated tank. It does not make electricity.

Systems come in three main types: off-grid (batteries, no KPLC), grid-tied (feeds your home alongside KPLC, usually no batteries) and hybrid (both, with batteries for blackouts). Our guide to types of solar systems explains which suits whom.

Pros and cons of solar energy

Advantages

Free fuel. Once installed, the sun costs nothing, and most of Kenya gets strong sun all year.
Power where the grid does not reach, or where it is unreliable.
Low running costs. Panels have no moving parts and need little more than cleaning.
Quiet and clean, with no fumes, unlike a diesel generator.
Scales from a lantern to a factory roof.

Disadvantages

High upfront cost for larger systems, especially batteries.
No sun, no power. Output drops on cloudy days and stops at night unless you have batteries.
Batteries wear out and need replacing, lead-acid sooner than lithium.
Fake and poor-quality products are common online.
Poor installation causes most failures. Use an EPRA-licensed installer.

Uses of solar energy in Kenya

Solar electricity is used across Kenya in many ways:

Homes: lighting, TV, phone charging, fridges and backup during blackouts. See home solar systems.
Farms: water pumping and irrigation, solar dryers for crops, incubators for poultry, electric fences, and powering milking machines and milk cooling on dairy farms where the system is sized for the motor.
Businesses: shops, salons, hotels, schools and clinics cut power bills with commercial solar.
Water heating: solar water heaters on homes, hotels and hostels.
Public spaces: solar street lights and security lights.
The national grid: large solar power projects in Kenya feed the grid. Read about solar power plants in Kenya, including Garissa and Malindi.

The Kenyan solar market

Kenya has a large and busy solar market, from pay-as-you-go lanterns and kits sold to rural homes, to installers fitting systems on homes, farms, factories and offices. The sector is regulated by EPRA, which licenses solar contractors, vendors, importers and technicians.

The EPRA contractor register shows how crowded it is: on 12 October 2026 it listed 1,072 solar PV contractor and vendor licences held by 676 companies. Many more traders sell solar products without a licence to install. For a buyer, that means plenty of choice, but also a real need to check who you are dealing with. This directory matches companies against the EPRA register for exactly that reason. Compare the best solar companies in Kenya.

Starting a solar business in Kenya

If you want to sell or install solar, plan for these steps:

Choose your lane. Retail of products, installation for homes, commercial installation, pumps and irrigation, or servicing and repair. Each needs different skills and capital.
Get licensed. Installing solar PV requires an EPRA licence. A company needs a licensed technician: Class T3 for a C1 contractor licence, and at least Class T2 for a V1 vendor or V2 importer licence. Our EPRA solar licence guide lists the classes, fees and requirements.
Get the tools. EPRA inspects for an earth loop impedance tester, an insulation resistance tester, an earth resistance tester and a clamp meter.
Find reliable suppliers. Buy from importers who give datasheets and warranties. Your name is on every system you install.
Build trust. Show your licence number, keep photos of finished work and give each client a wiring diagram and warranty card.

Licensed installers can list their company on this directory to receive quote requests.

Kenya solar expos and trade shows

Solar and energy trade shows are held in Kenya, where suppliers, importers and installers show products and meet buyers. Dates and venues change from year to year, so check the organisers' own websites for current details before you plan a visit. Treat any exhibitor like any other supplier: ask for its EPRA licence and product datasheets.
