Grid-Tie vs Off-Grid Solar Systems
Understanding the difference between grid-tie and off-grid systems helps you choose the right solution.
Grid-Tie Systems
Grid-tie systems connect to Kenya Power’s electrical grid, allowing you to use solar power during the day while drawing from the grid when needed. Benefits include lower initial cost (no batteries required), net metering opportunities in some areas, unlimited power availability, and simpler maintenance.
However, grid-tie systems shut down during power outages for safety reasons. If backup power during outages is important, you need a hybrid system with batteries.
Off-Grid Systems
Off-grid systems operate independently from the electrical grid, ideal for rural areas or achieving complete energy independence. These systems include battery storage, providing power 24/7 regardless of sunshine or grid availability.
Off-grid systems cost more initially due to batteries but provide complete energy independence, protection from rising electricity costs, and power in areas without grid access.
Hybrid Systems
Hybrid systems combine the best of both worlds, connecting to the grid while including battery backup. You use solar power first, store excess in batteries, and only draw from the grid when both solar and batteries are depleted. During outages, your essential appliances continue running on solar and battery power.
System Comparison Costs
| System Type | 5kW Installation Cost (KSh) | Best For |
|---|---|---|
| Grid-Tie | 400,000 – 550,000 | Urban areas with reliable grid |
| Off-Grid | 650,000 – 900,000 | Rural areas, energy independence |
| Hybrid | 550,000 – 750,000 | Urban areas needing backup power |
“Hybrid systems are becoming increasingly popular in Nairobi due to frequent power outages. The ability to keep essential appliances running during blackouts makes the extra investment worthwhile for many homeowners.”
