Principles of Solar Photovoltaics

Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and when combined with power controllers and other components form a photovoltaic power generation device.

Photovoltaic power generation is based on the principle of the photovoltaic effect, using solar cells to directly convert solar energy into electrical energy. Whether it is used independently or connected to the grid for power generation, photovoltaic power generation systems are mainly composed of solar panels (components), controllers, and inverters.

Solar energy is a kind of renewable "green" energy that is completely powered by the sun, but how exactly do photovoltaic modules convert solar energy into electricity?

1. After the photovoltaic panel absorbs sunlight, it converts solar radiant energy into direct current.

2. Photovoltaic inverter converts direct current into alternating current.

3. The generated electricity can either be directly stored in the storage battery or be integrated into the grid through an inverter.

4. Power grid dispatches and uses electric energy

We are a company specializing in remote monitoring and control of the solar system through our wireless Ad-Hoc technology. Our system could help you to realize real-time controlling whether the photovoltaic panels are working well and monitor the electricity generated every hour, every day, every month, and year. If you are interested in this program or you are just going to the solar PV system, please feel free to contact us.
