1. Determine the energy consumption of the air conditioner:
A 2-ton air conditioner typically has a cooling capacity of 24,000 British Thermal Units per hour (BTU/hr). To convert this to watts, we multiply it by 0.293:
Energy consumption = 24,000 BTU/hr * 0.293 = 7072 watts
2. Calculate the daily energy consumption:
Assuming the air conditioner runs for 8 hours a day, the daily energy consumption would be:
Daily energy consumption = Energy consumption per hour * Operating hours per day
= 7072 watts * 8 hours = 56,576 watt-hours (Wh)
3. Determine the wattage rating of the solar panels:
To generate enough electricity to power the air conditioner during the day, we need to install solar panels with a combined wattage rating that exceeds the daily energy consumption. Let's assume we want to generate enough electricity to cover the air conditioner's needs during peak hours (for example, 4 hours in the afternoon).
Solar panel wattage rating = Daily energy consumption / Peak operating hours
= 56,576 Wh / 4 hours = 14,144 watts
4. Select solar panels:
Based on the calculated wattage rating, you can choose solar panels with appropriate power output. For example, you could use 28 solar panels rated at 500 watts each, which would provide a total of 14,000 watts (28 panels x 500 watts).
5. Consider additional factors:
Keep in mind that the actual solar panel requirements may vary depending on factors such as the efficiency of the solar panels, geographic location, shading, and desired backup power capacity. It's recommended to consult with a solar installer or an energy expert for a more precise assessment of your specific needs and system design.
