However, many Kenyans end up losing money on solar installations because of common but avoidable mistakes. At Unique Solarkenya Limited, we regularly meet clients who already invested in solar but are unhappy with performance, reliability, or costs.
Here are the top solar mistakes that cost Kenyans money — and how to avoid them.
1. Choosing a Solar System Based on Price Only
One of the biggest solar mistakes in Kenya is choosing the cheapest quotation.
Low-cost systems often include:
Poor-quality solar panels
Fake or refurbished inverters
Undersized or low-grade batteries
Important to know:
A cheap solar system that fails after one year is more expensive than a quality system that lasts 15–25 years.
How to avoid this mistake:
Compare system capacity, warranties, and installer experience — not just price.
2. Installing an Undersized Solar Power System
Many installers promise that a small system can power everything. After installation, clients experience:
Power trips at night
Fridges and TVs shutting down
Batteries failing prematurely
This happens when the solar system is not sized correctly.
How to avoid it:
Always insist on a proper load assessment, including:
Appliances used
Power ratings
Daily usage hours
Future expansion plans
At Unique Solarkenya, every solar installation starts with a detailed load analysis.
3. Using Low-Quality or Wrong Solar Batteries
Batteries are the most critical and expensive part of a solar power system.
Common battery mistakes in Kenya include:
Using cheap lead-acid batteries for heavy loads
Mixing old and new batteries
Poor battery protection and ventilation
Result: Short battery lifespan, weak performance, and frequent replacements.
How to avoid it:
Choose the correct battery type (Lithium or high-quality deep-cycle) and ensure proper battery management.
4. Poor Solar Installation Workmanship
Even the best solar equipment can fail due to poor installation practices.
Common problems include:
Loose DC connections
Incorrect cable sizes
Poor earthing and surge protection
Wrong panel orientation and tilt angle
These issues cause energy losses, equipment damage, and safety risks.
How to avoid it:
Work with an experienced and professional solar installer — not trial-and-error fundis.
5. Believing Unrealistic Solar Promises
Be cautious if an installer promises:
“Zero Kenya Power bills guaranteed”
“Solar will power cookers and heaters cheaply”
“No maintenance needed forever”
Solar energy is powerful, but it has practical limitations.
How to avoid it:
Choose an installer who explains what solar can and cannot realistically do for your home or business.
6. Failing to Plan for Future Power Needs
Many clients later want to add:
Borehole pumps
Air conditioners
More rooms or tenants
Business equipment
If the system was not designed for expansion, upgrades become expensive.
How to avoid it:
Design your solar system with future growth in mind:
Higher inverter capacity
Expandable battery systems
Adequate roof space for more panels
7. Choosing a Solar Installer Without After-Sales Support
Some installers disappear once payment is made.
When problems arise:
No technical support
No warranty assistance
No system maintenance
How to avoid it:
Choose a solar company with a physical presence, clear warranties, and ongoing support.
