Solar Panel
Solar cell modules, also called solar power panels, are the core part of solar power generation systems and the most valuable part of solar power generation systems. It has the characteristics of long service life and strong mechanical resistance to pressure. Its function is to convert the radiant energy of sunlight to electric energy and send it to the battery bank for storage, or it can be used directly to drive the load. For a solar power panel, the solar cell module plays an important role in its funtion. For example, a good battery storage system for solar panel can provide a better using experience.
As a mature poly solar panel supplier& monocrystalline solar panel manufacturersin China, we have types of monocrystalline solar panels for sale, including shingled solar pv module, half cut monocrystalline silicon and polycrystalline silicon. The difference between mono and poly solar panels will be displayed in the follows.
The Structure of Solar Panel
Tempered glass: It is used to protect the main body of solar cells, and its selection requirements are that the light transmittance must be high and tempered.
EVA: Used to bond and fix the tempered glass and the main body of the power generation. The quality of the transparent EVA material directly affects the service life of the components.
Cells: The main function is to generate electricity. The mainstream in the market is crystalline silicon solar cells.
Backplane: The role is to seal, insulate, and waterproof.
Aluminum alloy: protect the solar panel, its certain sealing and supporting function.
Junction box: protects the entire power generation system and acts as a current transfer station.
Silicone: Sealing function, used to seal the junction between the component and the aluminum alloy frame, component and junction box.
Comparison Between Monocrystalline and Polycrystalline Solar Panels
The appearance and photoelectric conversion efficiency of monocrystalline and polycrystalline solar power panels are different due to their different processing techniques.
Appearance
The four corners of the monocrystalline solar cell modules are arc shape without a pattern on the surface, and they are dark blue, packaged nearly black. While the four corners of the polycrystalline solar panels are square, and there are patterns similar to the snow crystal pattern on the surface. Polycrystalline solar panels are usually light blue.
Photoelectric conversion efficiency
At present, the photoelectric conversion efficiency of monocrystalline solar panels is about 15%, and the highest reaches 24%. The photoelectric conversion efficiency of polycrystalline solar panels is about 12%.
How Solar Panels Work?
Sunlight shines on the semiconductor p-n junction to form new hole-electron pairs. Under the action of the p-n junction electric field, holes flow from the p-region to the n-region, and electrons flow from the n region to the p-region, and a current is formed after the circuit is connected. This is how the solar panel systems work.
FAQs of Solar Panel
QWhich one should I choose for monocrystalline silicon and polycrystalline silicon solar panels?
A
Monocrystalline silicon and polycrystalline silicon solar panels have their own advantages and disadvantages, and their poly solar panel priceare different. Please choose according to project requirements or local hot-selling types.
QWhy is the price per watt of a small-watt solar panel more expensive than a large-watt solar panel?
A
The cost of solar panels is affected by cell utilization, labor, and other accessories and consumables. The production of low-power solar panels is far greater than high-power solar panels in terms of cell utilization and labor. In principle, solar panel power The larger the price, the higher the price/performance ratio.
QHow is the price of solar panels calculated?
A
Generally, the price of solar panels is calculated according to the price per watt. For example: the price of a 350 solar panel is $0.22*350W.
QCan samples be provided for solar panels?
A
Due to the special structure and shape of solar panels, samples are likely to be damaged even if protective measures are taken during international transportation. We will not compensate for damages in the logistics process. We use each wooden pallet as the minimum order quantity. If you have any questions about the product and are not at ease, you are also welcome to visit the factory.
