Off-Grid Solar Systems in Kenya.

Off-Grid Solar Systems in Kenya: The Future of Energy Independence.

By RiiSun Solar Energy Experts.

Empowering Kenyan Homes and Businesses with Reliable, Independent Power Solutions.

Off-Grid Solar Systems in Kenya. Kenya’s energy landscape is changing fast. Across the country—especially in rural and peri-urban areas—more Kenyans are moving away from unreliable or unavailable grid power (KPLC) and embracing off-grid solar systems as their main source of electricity. At the forefront of this energy revolution is RiiSun Solar Energy Experts—a trusted solar installer delivering sustainable energy solutions to homes, farms, schools, health facilities, and businesses nationwide.

Why Off-Grid Solar Systems Are Gaining Popularity in Kenya

Millions of Kenyans still live in areas with:

• Limited or no access to KPLC.
• Frequent blackouts or power fluctuations.
• High and unpredictable electricity bills.
• Long delays in rural electrification.

With rising KPLC tariffs and unreliable grid supply, off-grid and hybrid solar systems have become the go-to solution for reliable, affordable, and clean energy.

RiiSun Solar Energy Experts designs, supplies, and installs solar systems across the country—ensuring all Kenyans, no matter their location, have access to energy independence.

What Is an Off-Grid Solar System?

An off-grid solar system is a complete, standalone power setup that works independently of the national electricity grid (KPLC).

It includes:

• Solar panels.
• Battery storage systems.
• Charge controller.
• Inverter (to convert DC to AC).
• Optional backup generator.

These systems are designed to generate, store, and supply all the power you need—even at night or during cloudy days.

Where We Offer Off-Grid Solutions

• Turkana, Marsabit, and Isiolo – We power remote homesteads and boreholes with solar water pumps and lighting systems.
• Kitui, Makueni, and Taita Taveta – We install solar for off-grid farms, dispensaries, and boarding schools.
• Trans Nzoia and Bungoma – We help farmers switch from diesel to solar irrigation systems.
• Lamu and Kwale – We power beach hotels and resorts fully on solar.

Whether you’re in a remote village or off-grid town, RiiSun comes to you with customized solutions.

Hybrid Inverters vs. Grid-Tied Systems

Understanding the difference between solar inverter types is key when deciding what system to install. At RiiSun, we help clients select the most efficient and reliable system for their area and energy needs.

🔹 Hybrid Inverter Systems

A hybrid inverter connects to solar panels, batteries, and the grid (KPLC or generator). It intelligently switches between sources to keep your power flowing.

Benefits:

• Uses solar during the day.
• Stores excess power in batteries for night use.
• Switches to KPLC or generator only when needed.
• Works during blackouts.

Where We Install Hybrid Systems:

• Kisumu, Eldoret, and Meru – Ideal for homes that have KPLC but suffer from outages.
• Kikuyu, Kitengela, and Thika – We serve residential estates needing backup power.
• Embu, Kericho, and Naivasha – We help hotels, hospitals, and private clinics stay powered 24/7.

🔸 Grid-Tied Systems

A grid-tied system is connected to KPLC and relies on the grid to operate. It reduces your power bill but does not work when the grid is down unless combined with batteries.

Benefits:

• Cost-effective for urban businesses and institutions.
• Great for reducing electricity bills during daytime operations.

Limitations:

• Shuts down during blackouts.
• Not suitable for off-grid or rural areas.

Where We Install Grid-Tied Systems:

• Nairobi CBD, Westlands, and Industrial Area – We support offices and warehouses.
• Mombasa and Nakuru – We install for shopping malls, supermarkets, and commercial buildings.
