Solar energy is a renewable or ‘green’ energy powered entirely by the sun. But how do solar PV panels turn sunlight into electricity?

Types of solar panels

Since each solar installation must address numerous space and shading limitations, no one-size-fits-all solar solution exists. Trina solar provides a range of different solar panels and solutions to cater to the various needs of residential, commercial and large-scale utility projects.

There are two main types of PV solar panels used in solar systems: monocrystalline and multicrystalline.

1. Solar PV panels capture sunlight, causing electrons in the panel’s silicon cells to release energy that becomes direct current (DC) electricity.

2. An inverter converts the DC into alternating current (AC) electricity, making it useable for homes and businesses.

3. Excess electricity can be stored in a battery or fed back into the power grid.

4. Additional electricity can be pulled from the grid if you need more power than your solar panels can generate.
