1. Understanding Your Business’s Energy Needs
The first step is analyzing how much electricity your business consumes. You can find this information on your electricity bill, usually measured in kilowatt-hours (kWh) per month.
For example, if your business uses 10,000 kWh per month, you’ll need a solar system that can generate a similar amount of energy to offset your consumption.
2. Calculating the Number of Solar Panels Needed
The number of solar panels depends on:
- Your energy consumption (kWh per month)
- The efficiency of solar panels (measured in watts per panel)
- The amount of sunlight your location receives
On average, a 400W solar panel produces about 1.6 kWh per day in good sunlight conditions. A simple formula to estimate the number of panels is:
Total Energy Needed (kWh per month) ÷ (Daily Energy per Panel × 30 days) = Number of Panels
For example, if you need 10,000 kWh per month and each panel generates 48 kWh per month, you’ll require:
10,000 ÷ 48 = approx. 209 panels
This number may vary based on efficiency, shading, and climate conditions.
3. Roof Space Considerations
Commercial buildings often have large flat roofs, making them ideal for solar panels. However, it’s crucial to check:
✔ Available roof area
✔ Structural capacity to support solar panels
✔ Possible shading from nearby buildings or trees
If roof space is limited, high-efficiency panels like SolarEdge Smart Panels can generate more power in less space.
4. Additional Factors to Consider
- Battery Storage – If your business operates at night or during peak hours, installing SolarEdge battery storage can maximize energy independence.
- Energy Consumption Growth – If you plan to expand your business, consider a system that can be scaled up.
- Local Incentives & Financing – Many governments offer tax credits or grants for businesses investing in solar energy.
