Solar panel storage battery prices？This should be analyzed according to the specific situation。The solar power generation system is composed of solar panel, solar controller and battery. The price of solar panels varies with different materials. The solar panels are divided into crystalline silicon (single crystal, polycrystalline, Sunpower) solar panels and amorphous silicon (CIGS, etc.), The order of conversion efficiency from high to low is: Sunpower solar cells (conversion efficiency is about 22%)>single crystal solar cells (conversion efficiency is about 20%)>polycrystalline solar cells (conversion efficiency is about 18%)>amorphous solar cells (conversion efficiency is about 14%). The price from high to low is: amorphous silicon solar cells>Sunpower solar cells>single crystal solar cells>polycrystalline solar cells. Secondly, the surface material, while ensuring the light transmittance, should also consider its waterproof and other properties. The surface material is divided into tempered glass, fabric tempered glass, PET, EFFE, TPT and other materials. However, if one square meter is calculated, the area you use is usually larger than the actual coverage area. The actual selection of these materials depends on the service environment of the product itself, as well as the use scenario, and the service life of the product. For example, the service life of glass is relatively long, and its corrosion resistance is relatively high, but its volume and weight are far superior to those of other products. If PET has a short service life of about 3-5 years, its price will be relatively cheap. However, if you use it in the seaside, where the salt fog is heavy, it is easy to cause problems such as surface desanding. If you use it in other places in the Central Plains, there is no big problem, It is mainly decided according to the actual situation. Secondly, EVA is in the form of milky white solid at room temperature. After being laminated at high temperature, EVA is in the transparent state of liquid. Its main function is to bond the surface material of the solar panel, the battery chip and the back plate of the solar panel together, and to ensure that it is transparent, which also ensures the transparency of the surface material and facilitates the production of large goods.
Secondly, there are many factors affecting the price of lifepo4 lithium battery 10kwh. For example, from the perspective of the material of battery cells, the price of lithium batteries is definitely higher than that of lead-acid batteries, and lithium batteries are divided into lithium iron phosphate batteries and ternary lithium batteries. In addition to the market demand, for example, since the second half of 2021, the safety performance of lithium iron phosphate batteries is higher than that of ternary lithium batteries. During the growth period of the household energy storage market, from the second half of 2021 to the present, The price of lithium iron phosphate battery is higher than that of ternary lithium battery. In addition, the battery accounting method is generally based on kilowatt hours. Therefore, the 20 kwh battery price is higher than the 5 kwh wall mounted battery storage.
There is also the price of inverter, because the direct output of solar energy is generally 12 V DC, 24 V DC and 48 V DC. In order to provide power to 220 V AC equipment, it is necessary to convert the DC energy generated by the solar power generation system into AC power, so a DC AC inverter is required. This also determines that the higher the power of the inverter, the higher the price,
To sum up, the solar energy storage battery price can only be quoted accurately if the customer gives specific requirements. However, as a lithium battery manufacturer, ZXDY's price to the customer must be competitive in the market
