How to Choose Solar Batteries — Complete Guide
Solar Batteries in Kenya: How to Choose the Right One
Energy storage is critical for any solar system in Kenya. Without batteries, your solar system can only power your home during daylight hours. Here's everything you need to know about choosing the right solar batteries for your needs.
Lithium vs Gel Batteries
| Feature | Lithium (LiFePO4) | Gel (Lead-Acid) | |---------|-------------------|-----------------| | Lifespan | 6,000+ cycles (15+ years) | 1,500 cycles (5-7 years) | | Depth of Discharge | 90-95% | 50% | | Weight | Light | Heavy | | Maintenance | None | Minimal | | Cost per kWh | Higher upfront, lower lifetime | Lower upfront, higher lifetime |
Our recommendation: For most Kenyan homes, lithium batteries provide the best long-term value despite higher upfront costs.
How to Size Your Battery Bank
The right battery capacity depends on your energy needs and how many hours of backup you want:
- Calculate daily usage: Add up watt-hours of all appliances
- Determine backup hours: How many hours do you need power when there's no sun?
- Apply depth of discharge: Divide by 0.9 for lithium or 0.5 for gel
- Add safety margin: Add 20% for efficiency losses
Example: A home using 10kWh per day wanting 12 hours backup needs approximately 7kWh of lithium battery capacity.
