December 22, 2025Felicity 100AH 12V Solar Gel Battery in Kenya
December 22, 2025As Nairobi’s population grows and electricity costs rise, more homeowners and property developers are turning to solar power solutions for apartments to reduce energy expenses, increase reliability, and add long-term value to their properties. Whether you’re a landlord managing rental units or a family living in a multi-bedroom home, investing in solar energy is a smart, future-proof decision.
At Happy Solar System, we offer tailored solar power systems for apartments, gated communities, townhouses, and individual homes across Nairobi and its environs.
Why Solar Power Makes Sense in Nairobi
1. Cost Savings on Electricity Bills
Electricity rates in Kenya are among the highest in East Africa. With a solar system installed, households can save up to 70% on monthly power bills. For a family spending KSh 5,000 monthly on electricity, this could mean savings of over KSh 42,000 annually.
Example:
A 3-bedroom apartment in South C with an average consumption of 10 kWh/day installed a 3kW solar system with lithium battery backup. The monthly power bill dropped from KSh 6,000 to KSh 1,800—a 70% reduction.
2. Reliable Power Supply During Outages
Kenya Power outages, especially in some estates like Rongai, Komarock, and parts of Lang’ata, are still frequent. Solar energy systems with battery storage ensure uninterrupted power for essential appliances like lighting, fridges, routers, TVs, and security systems.
Example:
A gated estate in Syokimau equipped every house with a hybrid solar power system with a 5kWh battery. During outages, homeowners didn’t need to run noisy generators, and essential devices continued working smoothly.
3. Increase Property Value
Homes and apartments fitted with solar systems are more attractive to tenants and buyers. Solar is increasingly seen as a modern, eco-conscious upgrade. In fact, property value can increase by 5-10% with a solar power system installed.
Example:
A landlord in Kilimani fitted a 5-unit block with solar water heaters and solar lighting in common areas. Within two weeks, all units were fully occupied and the rent increased by KSh 3,000 per unit due to the solar savings.
4. Environmental Sustainability
Nairobi’s air pollution from diesel generators and vehicle emissions is a major concern. By switching to solar, residents reduce their carbon footprint and support clean, renewable energy for a healthier future.
5. Shared Solar for Apartments
For multi-unit buildings, solar systems can be designed to power shared amenities like:
- Perimeter/security lighting
- Water pumps
- CCTV systems
- Common stairwell lighting
- Electric gates
This significantly reduces the landlord’s overheads and enhances security and livability.
