The video discusses how to calculate the energy consumption of an air conditioner and how many solar panels are needed to offset this consumption. The air conditioner in question is a 9,000 BTU unit that is used for 8 hours a day for 30 days. The monthly consumption of this unit is calculated to be 136.8 kilowatt hours.
The video then calculates how many solar panels are needed to generate this amount of energy. It uses a 665 watt solar panel as an example, with an average daily radiation of 5.36 kWh per square meter in the city of Belo Horizonte, Brazil. The efficiency of the system is assumed to be 75%, which is a common value used in the industry.
The energy generated by one solar panel is calculated to be 80.2 kilowatt hours per month. To generate 136.8 kilowatt hours per month, which is the consumption of the air conditioner, the video suggests using two 665 watt solar panels. This would generate a surplus of energy, effectively making the air conditioner free to use.
