Solar Energy Solutions in Kenya: Powering Homes, Businesses & Security Systems
Power Ratings for Common Appliances In Kenya. At Riisun Solar Energy Experts, we specialize in designing solar systems for all energy needs—from household appliances to security systems, workshops, and farms. Below is a detailed power consumption guide to help you calculate your solar requirements accurately.
Household & Office Appliances.
| Appliance | Power (Watts) | Daily Usage (Hours) | Daily Consumption (Wh) |
|---|---|---|---|
| LED Bulb | 5 – 10 | 5 | 25 – 50 |
| Refrigerator (Inverter) | 100 – 250 | 8 (cycling) | 800 – 2000 |
| TV (32″ LED) | 30 – 70 | 4 | 120 – 280 |
| Laptop | 30 – 90 | 6 | 180 – 540 |
| Microwave | 800 – 1500 | 0.5 | 400 – 750 |
| Water Pump (½ HP) | 400 – 750 | 1 | 400 – 750 |
Security & Electric Fencing.
| Device | Power (Watts) | Daily Usage (Hours) | Daily Consumption (Wh) |
|---|---|---|---|
| Analog CCTV Camera | 5 – 15 | 24 | 120 – 360 |
| IP CCTV Camera | 7 – 20 | 24 | 168 – 480 |
| NVR (4-channel) | 30 – 60 | 24 | 720 – 1440 |
| Electric Fence Charger | 10 – 50 | 24 | 240 – 1200 |
| Gate Motor | 100 – 300 | 0.2 (12 min/day) | 20 – 60 |
Workshop & Power Tools.
| Tool | Power (Watts) | Daily Usage (Hours) | Daily Consumption (Wh) |
|---|---|---|---|
| Angle Grinder | 500 – 1500 | 0.5 | 250 – 750 |
| Drill Machine | 300 – 800 | 0.5 | 150 – 400 |
| Welding Machine | 2000 – 5000 | 0.5 | 1000 – 2500 |
| Circular Saw | 800 – 1500 | 0.3 | 240 – 450 |
| Air Compressor (1HP) | 750 – 1500 | 0.5 | 375 – 750 |
(Note: Power tools are intermittent loads but require high surge power—ensure your inverter can handle the peak wattage!)
IT & Networking Equipment.
| Device | Power (Watts) | Daily Usage (Hours) | Daily Consumption (Wh) |
|---|---|---|---|
| Wi-Fi Router | 5 – 15 | 24 | 120 – 360 |
| PoE Switch (8-port) | 15 – 40 | 24 | 360 – 960 |
| Desktop PC | 80 – 250 | 8 | 640 – 2000 |
| Printer (Laser) | 300 – 800 | 0.5 | 150 – 400 |
| UPS (500VA) | 30 – 100 | 24 (idle) | 720 – 2400 |
Example Solar Calculation for a Kenyan Home with Workshop & Security
1. Household & Office
- 5 LED Bulbs (10W, 5hrs/day) → 250Wh
- Fridge (200W, 8hrs/day) → 1600Wh
- TV (50W, 4hrs/day) → 200Wh
2. Security & Fencing
- 4 IP Cameras (15W, 24hrs/day) → 1440Wh
- NVR (50W, 24hrs/day) → 1200Wh
- Electric Fence (30W, 24hrs/day) → 720Wh
3. Workshop Tools (Intermittent Use)
- Angle Grinder (1000W, 0.5hrs/day) → 500Wh
- Drill (500W, 0.3hrs/day) → 150Wh
4. IT & Networking
- Wi-Fi Router (10W, 24hrs/day) → 240Wh
- Desktop PC (150W, 6hrs/day) → 900Wh
Total Daily Consumption = 250 + 1600 + 200 + 1440 + 1200 + 720 + 500 + 150 + 240 + 900 = 7300Wh (7.3kWh)
Recommended Solar System:
- 2000W Solar Inverter (with surge capacity for tools)
- 4 x 400W Solar Panels (1600W total, 6-8kWh/day generation)
- 2 x 200Ah Lithium Batteries (5.12kWh storage)
Key Considerations for Solar Systems
✔ Surge Power – Tools like grinders & welders need inverters with high peak capacity.
✔ 24/7 Loads – Security cameras & electric fences require deep-cycle batteries.
✔ Energy Efficiency – Use inverter appliances (fridges, ACs) to reduce power waste.
✔ Professional Audit – Get a free energy assessment from Riisun for accurate sizing.
