What is the input and output of 5 kW household solar PV power generation?

Introduction How much does it cost to input and output 5kW home solar PV? The investment of 5 kW household photovoltaic power generation is about 50,000 yuan, and the annual power is difficult to calculate if calculated based on all self-use. generation

What is the input and output of 5 kW household solar PV power generation?

A 5kw household photovoltaic investment is equivalent to about 50,000 yuan, and the output is difficult to calculate. If calculated on the basis of self-use, the annual electricity generation is about 7,500 kilowatt hours at one time, counting 1 yuan. , the annual output It is 7,500 yuan, so the cost can be recovered in 6 and a half years, and the remaining 13 and a half years will be profit.

You can calculate the overall profit yourself

Although the state still strongly supports photovoltaic energy production, as the popularity of photovoltaics becomes more and more high, the general trend is to reduce or even eliminate subsidies, which are crucial for the construction of photovoltaic power plants. Since the current cost of construction, operation and maintenance of photovoltaic power plants is still very high, reducing or removing subsidies in the futurewill make the cost recovery cycle linked to investment in photovoltaic plants longer and riskier. Most of the solar chips used in household photovoltaic power plants are crystalline silicon solar chips. On the surface, the initial conversion rate is high and the price is cheap. However, the problem of conversion efficiency decreasing year by year is inevitable. The effect significantly increases maintenance and repair costs. These hidden issues Expenses are an issue that needs to be addressed. Although copper indium gallium selenide thin film solar cell chips have no attenuation or hot spot effect, and are more cost-effective in the long term, the price is now about a quarter more expensive than crystalline silicon. the construction of photovoltaic plants is relatively low. Investing in the construction of photovoltaic power plantsIt will pay off in about 8-10 years and last for about 25 years, which is better than investing in hydroelectric and wind power plants.
