3.1. Formula for Calculating Solar Panel Needs
The formula to calculate the number of solar panels involves dividing your annual energy usage by the production ratio and the wattage of the solar panels.
Number of Solar Panels = (Annual Energy Usage in kWh) / (Production Ratio) / (Solar Panel Wattage)
- Annual Energy Usage: Your total energy consumption over the past year, obtained from your electricity bills.
- Production Ratio: A regional factor accounting for sunlight and weather conditions, influencing panel output.
- Solar Panel Wattage: The power output of each individual solar panel under ideal conditions.
3.2. Step-by-Step Calculation Example
To illustrate the calculation, let’s consider a household with an annual energy consumption of 12,000 kWh, a production ratio of 1.5, and solar panels with a wattage of 350 watts each.
Number of Solar Panels = (12,000 kWh) / (1.5) / (350 watts) = 22.86
Rounding up, this household would need approximately 23 solar panels to meet their energy needs.
3.3. Estimating Solar Panel System Size
Estimating the solar panel system size involves considering the total wattage and physical space required to install the necessary number of panels.
- Total Wattage: Multiply the number of solar panels by their individual wattage to find the total system wattage.
