6 FAQs about [Specialized thermal oil for photovoltaic panels]
Which working fluids are used in solar thermal applications?
Conventional working fluids such as water, glycol, and synthetic oils are commonly employed in solar thermal applications, but they have relatively low thermal conductivity, which leads to minimized heat transfer and lower thermal performance.
What is the difference between photovoltaic and solar thermal energy?
Photovoltaic energy is mainly used for electricity generation, both on a large scale in solar plants and on a low scale in domestic installations. On the other hand, solar thermal energy is used, mainly, to obtain solar thermal hot water, heating and cooling applications in diverse sectors and, more residually, electricity production. Durability.
