An off-grid solar system means you are completely independent from ZESA. No load shedding, no power cuts, no electricity bills. This guide covers everything you need to know about designing and installing an off-grid system for your home, farm, or business in Zimbabwe.
🔋 What is an Off-Grid Solar System?
An off-grid system generates and stores all your own electricity using solar panels and batteries. There is no connection to the national grid. It's ideal for rural areas, farms, lodges, and anyone tired of load shedding.
📦 Components of an Off-Grid System
- Solar panels – Generate electricity from sunlight
- Charge controller – Regulates battery charging (MPPT recommended)
- Battery bank – Stores energy for night and cloudy days
- Inverter – Converts DC battery power to AC for appliances
- Backup generator (optional) – For extended cloudy periods
🔧 Sizing Your Off-Grid System
To size your system, calculate your daily energy usage in kilowatt-hours (kWh).
Example: Small Home (3-4 people)
- Lights (10 x 10W for 5 hours): 0.5 kWh/day
- TV + decoder (100W for 6 hours): 0.6 kWh/day
- Laptop (60W for 4 hours): 0.24 kWh/day
- Fridge (150W x 8 hours runtime): 1.2 kWh/day
- Water pump (500W for 1 hour): 0.5 kWh/day
- Total: ~3-4 kWh/day
This requires approximately: 1.5kW-2kW of solar panels + 5kWh-8kWh of battery storage
💰 Off-Grid System Costs in Zimbabwe (2026)
| System Size | Daily Output | Battery Storage | Estimated Cost | Best For |
|---|---|---|---|---|
| 1kW - 1.5kW | 4-6 kWh | 5 kWh | $3,000 - $4,500 | Small cottage, basic home |
| 2kW - 3kW | 8-12 kWh | 10 kWh | $6,000 - $9,000 | 3-bedroom home |
| 4kW - 6kW | 16-24 kWh | 15-20 kWh | $12,000 - $18,000 | Large home, small business |
| 10kW+ | 40+ kWh | 30-50 kWh | $25,000 - $50,000 | Farm, lodge, factory |
🏞️ Off-Grid for Farms and Rural Properties
Farms have special needs including borehole pumps, electric fences, and agricultural equipment. ProExpert Services designs custom off-grid systems for:
- Agricultural irrigation pumps (solar water pumps)
- Livestock water systems
- Farm worker housing electrification
- Game lodges and safari camps
- Rural clinics and schools
🔄 Off-Grid vs Hybrid vs Grid-Tied
- Off-Grid: 100% independent, no ZESA connection. Best for rural areas or complete freedom from load shedding.
- Hybrid: Connected to grid but can run off-grid during load shedding. Best for urban homes wanting backup.
- Grid-Tied: No battery, reduces electricity bill but no power during load shedding.
🔧 Maintenance for Off-Grid Systems
- Clean solar panels every 2-3 months (or more in dusty areas)
- Check battery terminals and connections (quarterly)
- Monitor system performance via app or display
- For lead-acid batteries: check water levels monthly
- Lithium batteries: virtually maintenance-free
