There are two main types of solar energy technologies—photovoltaics (PV) and concentrating solar-thermal power (CSP). On this page you’ll find resources to learn what solar energy is; how you, your business, or your community can go solar; and find resources for every step of the way.
Solar technologies are categorized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on the distance from the Equator.
In a nutshell, solar panels generate electricity when photons (those particles of sunlight we just discussed) hit solar cells. The process is called the photovoltaic effect.

Plug-in solar, also called balcony solar, are solar panels that connect to a standard power outlet. They supply power directly to your home. They are a plug and play way to reduce our reliance on the electric grid and lower your energy bill without the need for a permit. Small scale plug-in systems can be placed on a balcony, in a front or backyard, or on a roof deck. You can also add a ...
People have used the sun's rays (solar radiation) for thousands of years for warmth and for drying food. Over time, we’ve developed technologies to capture solar energy for heat and to convert it into electricity. Radiant energy from the sun has powered life on earth for many millions of years.
