Solar energy is one of the most promising alternatives to traditional energy. Not only is solar energy clean, but it is also renewable and environmentally safe. Solar energy is harvested by solar panels which in turn can generate power depending on the system in place.
Photovoltaic (PV) and solar thermal energy are two kinds of solar panel systems. So, what is the difference between them? In this blog, we will get into what PV systems do, what solar thermal energy systems do, and which you should have.
What are Photovoltaic systems (PV)
Photovoltaic, or PV for short, is a solar panel system that uses sunlight to generate electricity. This is traditionally what you think of when the term solar panels are used. The solar panels draw in the sun’s radiation into the cells that convert it into a specific voltage.
These solar panels look like checkerboards and are placed in places with excellent access to sunlight like on top of roofs or open fields.
What are Solar Thermal Energy systems
Solar Thermal Energy is a solar panel system in which sunlight is used to heat a fluid. The fluid will then be used in a steam engine or something similar. Unlike PV systems, Solar Thermal Energy does not necessarily produce electricity.
The main use of Solar Thermal Energy systems is for water heating in combination with a central heating system.
What system should you use?
For most people, PV systems are the way to go. The versatility of PV outweighs what Solar Thermal Energy provides. However, both PV and Solar Thermal Energy qualify for tax credit. Although PV is a heftier initial investment and takes up more room, it does have a bigger payout.
