Daily electricity consumption is 200 kWh and solar energy can efficiently produce electricity for up to 6 hours per day. 200 kWh/6 hours = 34 kW. Taking into account the rainy weather, you will have to choose one of 100 kilowatts, which costs around 2 million. The area can be freely combined within 2000-3000 square meters. The current electricity generation cost of solar power generation systems is 1 yuan/kWh, calculated based on a lifespan of 25 years.
How much does it cost to produce domestic solar energy with a daily electricity consumption of around 10 degrees?
By August 2021, the price will be 4-5 yuan per meter.
The installation cost of photovoltaic power generation is mainly the cost of equipment, including: photovoltaic modules account for about 49% of the total investment, inverters and other electrical equipment representedent about 10%, cables and slices each represent about 10% and different photovoltaic installation companies have their own pricing standards.
Installation capacity varies greatly depending on component capacity and installation angle. Generally speaking, each kilowatt of photovoltaic power generation system can generate four kilowatt hours of electricity per day and requires 10 square meters of installation area. If the installation scale is 3-5kW, the investment cost will be about 30,000-50,000 yuan.
Precautions for solar photovoltaic power generation
For photovoltaic power generation systems that operate for a long time, the impact of dust accumulation on the panels cannot be underestimated. The dust on the surface of the panel has the function of reflecting, diffusing and absorbing solar radiation, whichwhich can reduce the sun's transmission, causing the panel to receive less solar radiation and reduce the power output. Its effect is proportional to the accumulated thickness. dust.
At the same time, other parts of the photovoltaic panel will also be corroded by wet dust, such as joints, brackets and other parts. The materials are mainly made of various types of metals. Corrosion can easily lead to damage. , weakened security and other problems, which may be damaged by natural factors such as strong winds and earthquakes, thereby reducing the lifespan of photovoltaic panels.
Nowadays, the cost of using solar energy for households is still relatively high. Electricity consumption of 10 kilowatt hours per day may not seem significant at first glance. In fact, electricity production needed.must be greater than 2 kilowatts, because it takes into account cloudy days, the real situation of not being able to generate electricity at night and possibly using electricity requires a relatively large capacity battery to store electricity . So your system will cost between 20,000 and 30,000 yuan. It can be used on household appliances such as televisions and computers as well as lighting. No matter how big or small the household appliances are, they won't work, such as air conditioners, induction cookers, microwave ovens, and water heaters.
