Photovoltaic panels are solar panels.
Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. The main material of most solar panels is “silicon”. but due to its high production cost, its widespread use still has certain limitations. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products. Solar power generation methods There are two solar power generation methods: one is the light-heat-electricity conversion method and the other is the direct light-electricity conversion method.
When light irradiates the surface of the solar cell, a ppart of the photons is absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to transition and become free electrons. accumulate on both sides of the P-N junction to form a potential difference, when the external circuit is connected, under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.
Features of energy production by photovoltaic panel
1 There are no rotating parts and no noise is generated.
2. No air pollution and no wastewater discharge.
3. There is no combustion process and no fuel is required.
4. Simple maintenance and low maintenance costs.
5. Reliable operation and no conconsumption of working fluids.
6. As a key element, solar cells have a long lifespan.
7. It starts quickly and can produce electricity when the sun shines. It is suitable for the construction of distributed substations.
8. It is easy to install and has a short construction period. It is easy to expand the scale of power generation as needed.
9. Suitable for all sizes (100W～100MW).
