Awesome work! Great idea and realization.
From 50 to 100 USD. (For example: given my suboptimal installation, I get 2 kWh of heat per hour from the collector. Average operating time in the cold season is 480 hours. The cost of 1 kilowatt of electricity in my country is 0.062 USD, spent electricity on the fan = 48 KWt, received heat = 960 KWt. It all depends on the number of sunny days)

Thanks. It was fun and interesting. I showed my children how to use broken toys, telling about new and "green" technologies.
