How self a home solar power

Want to install a power generation system is very simple, the main need five things: 1. Solar panels 2. Solar cable bracket 3. 4. 5. PV inverter grid company responsible for the installation of metering systems need to consider the next meter The design capacity of the home as a result of the system is generally around 1-5 kW, system design and installation is very simple, the inverter is based on the appropriate selection of 1-5 kW of installed capacity specifications of the machine can be. Following a 5KW home system, for example: 1. Solar panels (components) to select the current market is divided into amorphous silicon solar cells and crystalline silicon, the vast majority of the domestic photovoltaic power plant polysilicon material selection. If you choose to power of about 250W polycrystalline solar panels, then a 5KW system requires 20 panels. 2. Select the solar PV mounting bracket is a special bracket for solar photovoltaic systems in place, install solar panels fixed design. Generally materials are aluminum, stainless steel, hot dip galvanized after a longer service life. In China, south-facing solar panels are generally installed, users can choose to use a fixed bracket. 3. Select the cable solar panels is direct current generated by the inverter into alternating current, then we will solar panels to the DC side of the inverter section is called the DC side (DC side), requires the use of photovoltaic DC side Dedicated DC cable (DC cable). Taking into account the annual PV in outdoor applications, power stations often in harsh environmental conditions, such as strong ultraviolet radiation, ozone, extreme temperature changes and chemical attack and so on. This provides for PV cables must have the best weatherproof resistance, UV and ozone aggressive, and can withstand a wider range of temperature changes. It is recommended that the use of solar energy applications dedicated cable, which will affect the life of the whole system. 5KW PV system for a DC cable diameter is generally 4mm2 or 6mm2. Select the PV inverter 4. The role of the inverter: Power by solar panels made of a DC motor, household appliances can not be used directly, must be converted to alternating current by the inverter can home. Select the inverter must pass domestic CQC certification, some manufacturers of products taking into account factors that exports also have TUV or UL certification. 5. Grid Corporation responsible for the installation of metering meter (two-way meter) two-way metering electricity meter that can be measured and the power meter. Power and energy are all directions, from the perspective of electricity, electricity being counted as a positive power or electricity generation are counted as negative power or electricity, the meter can be read out via the display, respectively, and a positive charge Reverse electricity consumption data and store it. The reason is due to the installation of two-way meter Sunergy issued presence can not all be consumed by the user, but you need to lose the rest of the energy grid, the meter needs a digital metering; when PV can not meet the needs of the need to use the electric grid, This in turn requires the measurement of another figure, ordinary single piece meter can not meet this requirement, so the use of smart meters with two-way electricity metering functions. After the purchase, due to household wiring and system design is simple, the library has installed solar photovoltaic power stations for ordinary users, as long as one to two days to install debugging, and net realized. If the family has its own garden pool or a high-tech farms can choose a 10-20KW home system, 20KW systems usually takes about 80 250W solar panels, connected to a dual three-phase inverter 20KW In this case the inverter connection is relatively complex, the need to find a professional system integrators, considering wiring, inverters combine port, local weather and other factors to design and complete construction. 1-5KW home system diagram, see Figure see 10-20KW home system after a system is installed, the owners should be most concerned about the return on investment period. Benefit analysis of a system, you need to consider several aspects of owner-electricity power over the Internet, and government subsidies. Distributed PV subsidy nationwide standard for 0.42 yuan / kWh for a period of 20 years, in addition to cities around the photovoltaic power generation have different degrees of subsidies. Assume that the system is installed in Guangzhou, so individual users can enjoy 0.1 yuan / kWh subsidy for a period of 10 years; and for the owners of photovoltaic power stations, 0.2 yuan per watt also subsidize construction costs deductible. A 5KW system, input costs of about 50,000 yuan, the annual generating capacity of up to 5,000 degrees, the entire system is expected to recover the cost of inputs in the first eight years, and achieve profitability. New library Guangdong Solar Energy Technology Co. (http://www.solarstock.cn), specializes in solar power, distributed photovoltaic power, home solar power system solutions, to undertake factories, supermarkets, residential, solar greenhouses, solar fisheries and other solar power projects. Sun libraries adhering to the "focus for you to build solar power plant" concept focused to serve you. As photovoltaic applications technology innovator, Guangdong Solar Energy Technology Co., Ltd. With the new library for many years experience in this field for many owners successfully installed a rooftop solar power station, building-integrated photovoltaic systems (BIPV) and off-grid solar power plants. We offer a complete set of solar power generation solutions and services, all for higher output, lower costs and more reliable security. Sun library customers include residential, industrial zones, universities and government buildings, office buildings, commercial centers and the military and so on. Have signed cooperation program owners of solar power more and more, the library is to target the sun to reach 10,000 in 2018.
