Photovoltaic to the countryside, photovoltaic poverty alleviation, photovoltaic subsidies, these terms are more and more familiar to the people. Therefore, some people often ask this question: I plan to be a family photovoltaic grid-connected power station. How much electricity can I generate? Take a 60 square meter roof as an example The promotion of home photovoltaic power stations in cities is currently more difficult because the vast majority of urban households do not have the roof resources available for photovoltaic power generation, but they are only suitable for the promotion of independent units or villas in rural townships. Relatively speaking, each family's roof has an effective area of ​​60 square meters, even if it is very comfortable. Then, what is the maximum installed capacity of a 60-square-meter roof? How much electricity can I send per day? At present, home-grown photovoltaic power stations generally use single-crystal silicon components and polysilicon components. The general specification is 36V280W, and the single-block area is about 1.8 square meters. Photovoltaic module arrays are connected in different strings. The installation must use a reasonable tilt angle to select the correct lighting direction. Each array should be staggered by a certain distance in order to avoid overlapping with each other when sunlight shines. Blocking. At the same time, for the convenience of cleaning and maintenance, aisles must be reserved between PV arrays. Therefore, the 60-square-meter roof is recommended to install 20 photovoltaic modules reasonably, with an installed capacity of 5.6 KW and a total area of ​​36 square meters. How much electricity can a solar panel generate per day? This is mainly determined by factors such as photoelectric conversion efficiency of solar modules, sunshine hours, and installation elevation angle. The photoelectric conversion efficiency of a photovoltaic module refers to the ratio of the maximum output power of a photovoltaic module to the solar power irradiated on the module under standard test conditions. According to the “Opinions on Promoting the Application and Industrial Upgrade of Advanced Photovoltaic Technology Products†issued jointly by the National Energy Administration, the Ministry of Industry and Information Technology and the National Certification and Accreditation Administration on June 8, 2015, it is clear that polysilicon battery components and monocrystalline silicon The photoelectric conversion efficiency of the battery module is not less than 15.5% and 16%, respectively. Therefore, under the standard sunshine conditions (1000W/m2), the actual power of the photovoltaic module square is: 5.6KW/0.16=3.5KW, and the effective solar energy generation time is calculated according to the ideal 6 hours (10:00-16:00) ), can generate 21KWh per day. It is calculated for 240 days in the whole year (the monthly effective solar power generation time is 20 days), and the total photovoltaic power generation is 5040KWh. An important component of photovoltaic power stations is the photovoltaic array support. The bearing capacity of the roof structure is the main factor affecting the installation of the photovoltaic system. If it fails to meet the specification requirements, it must be reinforced and treated in order to ensure the safety and reliability of the house. In addition, before the brackets are fixed, care must be taken to maintain and waterproof the roof. At the same time, the obstructions around the house, such as large trees and nearby buildings, will directly affect the effective time and power generation efficiency of photovoltaic modules receiving solar radiation. Home photovoltaic power generation is connected to the public power grid in two different grid-connected schemes: AC single-phase 220V or three-phase 380V. If the single-phase 220V grid-connected, the power series of the grid-connected inverters are generally 3KW, 5KW; if the three-phase 380V grid-connected, the power series of the grid-connected inverters that are available for selection is generally more than 10KW.
