Solar PV Intro
Solar PV (photovoltaic) is different than Solar Thermal (ST). While PV is a newer and more advanced technology, installing a PV system is easier and more straightforward. This isn't to say one technology is better than the other. They are just different.
Solar Thermal Intro
Solar Thermal (ST) water heating is a great way to take advantage of free energy from the Sun. Before we go in-depth on how solar thermal water heating works, let's go over the bare essentials.
1) Solar Thermal water heating is different from Solar PV (electricity)
2) Solar Thermal water heating is different than Solar Thermal power generation.
