Arex Solar  The Best Photovoltaic Technology

How Solar Works

How solar works.

The free energy our sun gives to us every day is waiting for you to use it profitably. You can convert that energy into electricity, use it directly or feed it into your provider’s network. In many countries you receive an attractive compensation rate regulated by law.

How your power plant works.

1. Modules

Photovoltaic modules provided by Arex Solar consist of several interconnected solar cells made of the semiconductor silicon, which have a poly- or monocrystalline structure depending on the production technique used. A solar cell’s silicon is doped differently on the front and rear sides to create one positive and one negative charge carrier surplus, producing an electrical potential at the junction of the two differently doped layers. When sunlight strikes the solar cells, the silicon begins conducting and voltage is generated across the cells’ metal contacts, creating direct current.

How PV cells work

2. Inverter

Direct current created in the solar cells cannot be fed directly into the public grid: an inverter converts direct current into 230-volt alternating current so that it can be used normally.

3. Export meter

You can use the produced energy in your own home or feed it inot the grid. Grid-connected plants require an export meter that measures the energy fed into the grid in kilowatt hours (kWh).

4. Public grid

The alternating current created and fed into the public grid can then be used by all consumers.
