Everything you need to size your home's solar needs, estimate costs, and choose the right components.
Enter the number of each appliance you own to estimate daily energy use and the system size you need.
LED bulb (10W)
10 W × 6 h = 60 Wh
Ceiling fan (75W)
75 W × 8 h = 600 Wh
Television (120W)
120 W × 5 h = 600 Wh
Refrigerator (150W)
150 W × 8 h = 1200 Wh
Washing machine (500W)
500 W × 1 h = 500 Wh
Small AC unit (1000W)
1000 W × 4 h = 4000 Wh
Water pump (750W)
750 W × 2 h = 1500 Wh

Sudan enjoys some of the highest solar irradiance in the world — 9 to 11 hours of sunshine per day year-round, making it one of the best places on Earth to invest in solar energy.
Frequent power outages in many regions make solar systems a reliable way to keep the lights on 24 hours a day.
Conventional electricity costs keep rising, while solar offers a long-term economic alternative with payback in 3–5 years.
On-grid: Connects to the public utility grid. Ideal for areas with stable electricity and an export license. Lowers your bill but stops working during outages.
Off-grid: Operates fully independently with battery storage. The best option for rural areas of Sudan that are far from the grid.
Hybrid: Combines grid connection with batteries. Powers loads at night, stores surplus energy, and offers the most flexibility.
Step 1: List every electrical appliance in your home with its wattage and daily run-time. Multiply watts by hours to get daily consumption in Wh.
Step 2: Add a 20% safety margin to the daily total to cover efficiency losses and weather variation.
Step 3: Divide daily consumption by 5 effective sun-hours (Sudan average) to get panel size in kW. Example: a home using 4,000 Wh/day needs about 0.8–1.0 kW.
1 kW system (small home): SDG 150,000–200,000. Powers lights, TV, phone charging, and a fan.
2 kW system (medium home): SDG 280,000–380,000. Adds a small fridge, computer, and extra fans.
3–5 kW system (large home): SDG 350,000–600,000. Covers a small AC, washing machine, water pump, and multiple appliances.

Lead-acid (GEL/AGM): Lower cost (SDG 50,000–120,000), lasts 3–5 years. Good for tight budgets.
Lithium LiFePO4: Higher cost (SDG 200,000–500,000) but lasts 8–12 years and handles thousands of cycles. Best long-term value.
Inverter: Size by your peak appliance load. A 2–3 kW pure sine-wave inverter is enough for an average home and protects sensitive electronics.
