Is photovoltaic power equal to solar water heater?

At present, solar energy products mainly include the following types:

1. Solar photovoltaic panels.

Using monocrystalline silicon or polycrystalline silicon to make solar panels for power generation, that is, photovoltaic power generation mentioned in the problem.

Generally speaking, photovoltaic power generation belongs to photovoltaic industry.

2. Solar water heater.

Including glass vacuum tube solar water heater, flat plate solar collector, trough solar collector, Fresnel solar collector, tower solar collector, etc.

It belongs to photothermal industry.

Photovoltaic and photothermal are two different majors in the solar energy industry. They have different working principles and different product structures. Even as solar energy workers, they may only know one of them but not the other.
