Certainly! Here's a summarized version:
1. Determine the power consumption of the light in watts (W).
2. Decide the desired backup duration in hours.
3. Calculate the energy requirement: Energy Requirement (Wh) = Power Consumption (W) x Backup Duration (hours).
4. Account for system losses by multiplying the energy requirement by a factor (e.g., 1.2) to consider inefficiencies.
5. Select a battery capacity (rated in Ah or Wh) that meets or exceeds the adjusted energy requirement.
6. Consider battery efficiency and recommended depth of discharge (DoD) to adjust the battery capacity if necessary.
Remember, it's advisable to consult with a solar professional or engineer for accurate calculations and system design based on specific factors and requirements.
