Take into account the solar panel efficiency to calculate the total wattage required. Divide your daily power consumption by the efficiency of your solar panels to obtain the total wattage needed.
For example, if your daily power consumption is 8400 watt-hours and your panels are 20% efficient, you would need 42,000 watts of solar panels (8400 watts / 0.20).
3. Factor in Average Daily Sunlight Hours
Multiply the total wattage needed by the average daily sunlight hours in your location to determine the total watt-hours of energy your solar panels can generate each day.
For example, if you have 42,000 watts of solar panels and your location receives an average of 5 hours of sunlight per day, you would have 210,000 watt-hours of energy available daily (42,000 watts x 5 hours).
4. Consider Battery Storage Capacity
If you have a battery storage system, consider its capacity to determine the additional energy needed from your solar panels. Add the daily power consumption of your tools to the battery storage capacity to calculate the total daily power requirement.
For example, if your daily power consumption is 8400 watt-hours, and your battery has a capacity of 4000 watt-hours, your total daily power requirement would be 12,400 watt-hours (8400 + 4000).
5. Calculate the Final Number of Solar Panels
Take into account the solar panel efficiency and the total watt-hours of energy required to calculate the final number of solar panels needed. Divide the total watt-hours by the product of the panel efficiency and the average daily sunlight hours to obtain the number of panels required.
For example, if you have a total daily power requirement of 12,400 watt-hours, panels with 20% efficiency, and an average of 5 hours of sunlight per day, you would need 124 solar panels (12,400 / (0.20 x 5)).
Remember that this calculation is a rough estimate, and it’s recommended to consult with a professional solar installer to ensure accurate results based on your specific situation.
