All you need to know about solar energy.
Peak Sun Hours (PSH): What does it mean and how to estimate it?
Peak sun hours (PSH) is a parameter used to indicate the amount of energy per day that reaches a certain location on the earth’s surface from the sun. Knowing it will simplify calculations when planning a solar-powered system.
STC, PTC, NOCT: What do they mean and how to use them?
STC and PTC are both test conditions used to rate the performance of a photovoltaic module (PV panel), while NOCT is referred to the PV cell temperature and it’s obtained under prefixed environmental conditions. Of course, it’s not necessary to know what they are in order to buy a solar panel. However, if you want to make a better deal, these parameters are very handy. Let’s see how
What are the environmental impacts of solar energy?
The environmental impacts of a solar system could be mainly divided into 3 phases:
1. Production phase
2. Operating phase
3. End of life phase
