Technical FAQs 4

What is solar energy?

Solar energy is a form of carbon-free, renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use.

How do solar panels generate usable electricity?

Solar arrays create a usable electricity system for your home by producing direct current (DC) electricity. This is achieved through the photovoltaic effect, where solar cells convert sunlight into electrical energy.

What type of electricity does a solar panel use?

AC is the type of electrical current used when you plug appliances into normal wall sockets. What’s the difference between solar PV panels and solar thermal panels? Solar PV panels generate electricity, as described above, while solar thermal panels generate heat.

How do solar photovoltaic cells work?

Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)
