1. Solar Modules

Solar panels composed of groups of photovoltaic cells are installed on your roof.  The word photovoltaic (PV) comes from the Greek Phos, meaning light, and Volt, a unit of measurement named after Alessandro Volta, who invented the electric battery in 1800.

A PV cell is made of silicon semiconducting materials. Sunlight is made up of photons, or particles of solar energy. When the sun’s photons strike the semiconducting materials in a PV cell, some are reflected, some pass through, and others are absorbed by the cell. When this happens the photon’s energy is transferred to an electron in an atom of the semiconductor. The energized electron escapes from its normal position in the atom and becomes part of a direct current in an electrical circuit.

2. Inverter

The direct current (DC) electricity from the solar panels is sent to an inverter, where it is converted into standard alternating current (AC) electricity used in your home.

3. Electrical Panel

The AC electricity travels from the inverter to the electrical panel, or breaker box. This power is now ready for use in your home.

4. Utility Meter

A meter connected with your utility company monitors your electrical supply. If your solar system is producing more power than your family can immediately use, the excess is credited to your account.

5. Web-based Monitoring

With ECOApp systems you can also monitor the performance of your solar system 24/7 through your online account via a PC, iPhone and/or other Internet devices.

6. Utility Grid

You are still connected to the utility grid, from which you can draw electricity any time should you need more than your solar system is producing.
