Solar panels, inverters (photovoltaic modules that convert from DC voltage to AC voltage) distribution boxes, as well as the cost of the entire project. The above are the main photovoltaic modules. Through an app on the photovoltaic industry platform, I collected quotations for related components.

     ① Photovoltaic module LONGi's single crystal 355W module, LR4-60HPH 355W, 543 yuan per piece, which is 1.53 yuan/W (tax included), other products such as Canadian Solar 340W, CS3L-340P, 489.6 yuan/piece, that is 1.44 yuan/W

     ②Inverter Growatt three-phase 17kW Growatt MID 3850 yuan per unit, which is 0.23 yuan/W

     ③Distribution box Ruchangsong 10kW distribution box 699 yuan/piece

     The main accessories are priced as above. If it is an integrated solution, the solution given by the app (including three major items, distribution services, insurance, etc.) is 3.5 yuan/W.

     At present, most solar power stations on the market have a service life of 25 years and require regular maintenance.

     At present, the service life of photovoltaic power plants is about 25 years, which requires regular maintenance. We still take the industry downstream service provider Carbon Silver as an example. In addition to providing the service of installing power stations, Zhejiang Carbon Silver costs 200 per year for the maintenance of the power stations. The replacement of equipment failures requires exceptions. If it is calculated in 25 years If it is, the general maintenance cost is not less than 5000.
