01 What is the photovoltaic system for grid-connected households?

Solar panels can be divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells, and relatively rare chemical dye cells based on their materials;

Nowadays, there aren’t many mountaineers in China using solar charging panels, but in fact, this demand is becoming increasingly strong. After all, there are more and more devices that use electricity, and who doesn’t want a continuous supply of electricity?

Core component – solar cells

From a functional perspective, solar cells are semiconductor thin films obtained by processing silicon wafers, which can convert solar energy into electrical energy, determining the power generation capacity of photovoltaic systems.

11. Multiplex load calculation based on peak sunshine hours

11.1 Current

Solar module current=load daily power consumption (Wh)/system DC voltage (V) × Peak sunshine hours (h) × System efficiency coefficient

1. Conversion efficiency

η= Pm (peak power of solar cells)/A (solar cell area) × Pin (incident light power per unit area)

At present, solar street lights have been promoted and popularized in our lives. Solar street lights can be seen everywhere, in parks, roads, factories, communities, scenic spots, and even in most rural areas.

Flexible solar cell is a kind of thin film solar cell with advanced technology, excellent performance, low cost and wide applications. Its characteristic is that amorphous silicon coated with resin serves as the main photoelectric element layer and is laid flat on a flexible material substrate.

Selection of solar panel dimensions

BIPV, also known as Building Integrated PV, is the integration of photovoltaic buildings. PV stands for Photovoltage. BIPV technology is a technology that integrates solar power (photovoltaic) products into buildings.
