1. Heater Power Consumption: Determine the power consumption of the AC electric heater in watts. This information is usually provided on the heater's label or specifications.
2. Solar Panel Output: Solar panel output is measured in watts (W) and depends on the panel's size, efficiency, and sunlight conditions. To calculate the required solar panel output, you can use the formula:
Required Solar Panel Output = Heater Power Consumption / Solar Panel Efficiency
For example, if your AC electric heater consumes 1500 watts and you have solar panels with an efficiency of 20%, you will need a solar panel output of:
Required Solar Panel Output = 1500 W / 0.20 = 7500 W (or 7.5 kW)
3. Hours of Usage: Consider how many hours per day you will be using the heater. This will affect the total energy requirement and the size of the solar panel system.
4. Solar Insolation: The amount of sunlight available in your location will impact the energy production of the solar panel. Research the average daily solar insolation (measured in kilowatt-hours per square meter per day, kWh/m²/day) for your area.
5. Battery Storage: If you want to use the solar energy generated during the day to power the heater at night or during cloudy periods, you will need a battery storage system. This will add to the overall system cost.
Based on these factors, you can calculate the size of the solar panel system required to power your AC electric heater. It's recommended to consult with a professional solar installer or system designer for accurate calculations and recommendations based on your specific requirements and location.
