What are the different types of solar panels?

Before switching to solar energy, it is important to know there are different types of panels, as well as different installation types. The two main types of panels are photovoltaic panels and solar thermal panels; photovoltaic panels will convert thermal energy into electricity, and solar thermal panels turn solar energy into heat.

How do solar photovoltaic panels work?

Solar photovoltaic panels transform free energy from the sun into electricity. This is then converted from a DC current to an AC current via an inverter, to make it suitable for household use. The panels capture energy from the sun and convert it into DC electricity via groups of photovoltaic (PV) cells.

Where are solar panels usually located?

Solar panels are typically located on rooftops, ground areas, over parking lots and exterior corridors, or nearby walls, chosen based on the property’s conditions, requirements, and optimal sunlight exposure. How is solar energy used around the world?

How are solar panels arranged?

Solar panels are usually arranged in groups called arrays or systems. A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as controllers, meters, and trackers.

Can a photovoltaic panel be sold back?

If you install photovoltaic panels and you are connected to the grid, it is possible to sell your energy back to the national supply. In this case you have a choice to sell all of it (revente totale) or to use it for your own use primarily (autoconsommation) and sell back any surplus.

Are solar PV panels a good option for self-builders and renovators?

Solar PV panels have long been a popular renewable technology among self-builders and renovators. Thanks to a mixture of government incentives and falling technology prices, demand for solar photovoltaics (PV) has boomed over the last decade.
