Next, calculate the total watt-hours required per day for each appliance. To do this, multiply the wattage of each device by the number of hours you intend to use it daily. For instance, if a light bulb consumes 10 watts and is used for 5 hours, the calculation would be:
10 watts x 5 hours = 50 watt-hours.
After determining the daily watt-hours for each appliance, sum all these figures to acquire your total daily energy consumption. This number will give you a clear indication of how much energy you need to generate with your solar power system.
In addition to the total watt-hours, consider the efficiency of your solar panel system. Most solar panels operate at about 15-20% efficiency, meaning you will need a bit more capacity to meet your energy needs. To account for energy loss and fluctuations in sunlight, aim for a solar array that can produce 20-30% more energy than your calculated daily consumption.
For example, if your total daily consumption is 300 watt-hours, your solar panel system should ideally produce:
300 watt-hours x 1.3 (to account for efficiency) = 390 watt-hours.
Lastly, incorporate battery storage into your calculations. Batteries store the solar energy generated, allowing you to use power when sunlight isn’t available. Consider how many days of autonomy you desire (usually 1-3 days), and multiply your daily consumption by the number of days to determine your battery capacity needs.
