Solar thermal collectors for water heater 

Solar thermal collectors for water heater are very different for Solar photovoltaic panel
In this video, we will see details of solar thermal collectors
1. Evacuated tube collector
2. Evacuated tubes with heat pipes and
3. Flat plate collector.
the concept of the greenhouse effect as it relates to solar thermal collectors will also be discussed. Additionally, a comparison of the evacuated tube collector with the Flat plate collector will be done.
