With the continuous improvement of environmental awareness, more and more people are interested in using green energy. As an emerging clean energy source, photovoltaic power generation has attracted much attention. So, if we want to install photovoltaic energy production on the roof of our house, how much does it cost for an area of 100 square meters? This article will give you a detailed analysis of the costs and benefits of 100 square meters of photovoltaic power generation.
Operation steps for 100 square meters of photovoltaic power generation
1. Determine the installation location: Photovoltaic power generation should receive full sunlight, so the installation location should be on an open place. roof or ground.
2. Measure the area: measure the area of the installation location to determine the number of panelsx photovoltaics to be installed.
3. Choose photovoltaic panels: Choose suitable photovoltaic panels based on the size of the area and budget.
4. Installation bracket: The installation bracket should be fixed on the roof or ground to ensure that the photovoltaic panels can be installed on it stably.
5. Install photovoltaic panels: install the photovoltaic panels on the supports and connect the photovoltaic panels together.
6. Connect the cable: Connect the cable of the photovoltaic panel to the inverter, and the inverter converts DC power to AC power.
7. Connect to the grid: Connect the AC output of the inverter to the grid and the photovoltaic power generation can work normally.
Analysis of the cost of 100 square meters of photovoltaic energy production
The cost of 100 square meters of energy production photovoltaic mainly includes the following aspects:
1. Cost of photovoltaic panels: Photovoltaic panels cost is one of the main costs of photovoltaic energy production. The prices of photovoltaic panels of different brands and powers are also different. Generally speaking, 100 square meters of photovoltaic panels cost about 100,000 yuan.
2. Cost of Support: The cost of support cannot be ignored. The cost of a 100 square meter rack is about 20,000 yuan.
3. Inverter Cost: Inverter is also an important part of photovoltaic power generation. The cost of a 100 square meter inverter is about 30,000 yuan.
4. Installation Cost: Installation of photovoltaic power generation requires professionals. The installation cost for 100 square meters is about 50,000 yuan.
Therefore, the total cost of 100 square meters of productction of photovoltaic energy is about 200,000 yuan.
Revenue analysis of 100 square meters of photovoltaic power generation
The income of 100 square meters of photovoltaic power generation mainly comes from two aspects: government subsidies and income from electricity charges.
1. Government subsidies: According to national policies, each kilowatt hour of photovoltaic power generation can receive a certain subsidy. Based on the subsidy standard of 0.4 yuan per kilowatt hour, 100 square meters of photovoltaic power generation can receive a subsidy of about 6,000 yuan per year.
2. Electricity fee income: Photovoltaic power generation can sell the generated electricity to the grid, and the electricity price per kilowatt hour is about 0.5 yuan. Assuming that the annual electricity production of 100 square meters of energy productione photovoltaic is 8,000 kilowatt hours, the annual electricity income can be about 4,000 yuan.
Therefore, the annual income of 100 square meters of photovoltaic power generation is about 10,000 yuan. Based on this income calculation, the payback period for 100 square meters of Photovoltaic energy production is about 20 years.
