【Solar PV System Design :2 】What benefits can systems bring us?
Through 【Solar PV System Design:1】, we have preliminarily understood what solar photovoltaic system is.Thinking about installing solar photovoltaic systems in every home? What are the appropriate conditions for installing the system? Before we understand that we need to not install this system, okay? How can solar photovoltaic systems benefit us.
So what specific benefits can solar PV bring?It mainly contains the following 3 points：
1.Easy to use, avoid the inconvenience caused by power failure
Some areas are located in cities that consume a lot of electricity, and they will suffer from frequent blackouts due to the power rationing policy.If factories, office buildings and homes use solar photovoltaic systems to generate their own electricity, they can reduce the list of problems caused by frequent power outages: failure to deliver customer orders on time, hot weather, equipment can not be cooled.
In modern cities, all electrical appliances in people’s homes must be supported by electricity before they can be used. If the power is cut off, it will not only bring trouble, but also some electrical appliances will fail due to sudden power failure, affecting subsequent use.
2.It can save electricity bills and reduce household expenses
The solar system generates kilowatt hours (KWH) of power when it works. The unit of calculation for how much electricity you pay to the power company is ten million hours. Kilowatt hour refers to the use of 1000 watts (1000 watts) in one hour. If you use an appliance with a power of 1000 watts per minute, you use 16.67 w · h watt hours. If you use an appliance with a power of 1000 watts for 24 hours, you use 2400 watt hours or 2.4 kilowatt hours (KWH).
The solar system usually works between 9 a.m. and 4 p.m. to generate electricity. At other times of the day, it is difficult for the solar system to generate electricity, but the power demand of household appliances is 24 hours a day.
If you use an off grid solar system, you can store the excess power beyond the power demand during the day through the battery for use at night, so that you don’t need to obtain power from the power company to reduce the power cost.Assuming that your daily electricity consumption is 50KW. H, according to the average electricity price of 14.95 cents per kilowatt hour (KWH) in the United States in May, you can save about $7 a day.
If you are installing a On-Grid Solar Home System .The electricity your solar PV system generates during the day is sent to the power company, who will sell it for a price per kilowatt-hour (KWH) of electricity you send. Earn money this way.
There are two main ways to connect solar power generation to the grid: one is that all the generated electricity is connected to the grid for external supply; the other is that the generated electricity is first supplied for personal use, and the excess electricity is only connected to the grid.The economic benefits of the first method are definitely better. Because the price of solar power generation connected to the grid will be higher than the price of electricity supplied to users by the national grid. The second method will be more free, and you can freely dispose of your electricity.
Recently, European Commission President von der Leyen said that the European Union will limit the price of Russian oil .On September 2, the finance ministers of the group of seven issued a joint statement, announcing that they had agreed to impose a price ceiling on Russian oil and petroleum products.
Russia has announced that it will not supply oil and oil products to countries that support price caps on Russian oil, which means that electricity resources are more scarce and electricity prices are bound to rise. You can generate electricity through your own solar power system to ensure 24-hour electricity demand and reduce electricity bills.
3.Energy saving and environmental protection are conducive to the development of green environment
Up to now, hydropower generation and wind power generation only account for a small part of the electricity used in normal human life, and more rely on coal, natural gas and other resources for thermal power generation, and the excessive mining of coal has led to frequent occurrence of natural disasters in many places. , such as landslides and landslides. The use of solar photovoltaic power generation can be more energy-saving and environmentally friendly, and it is also in line with the strategic goals of sustainable development.
Photovoltaic power generation can reduce the over-exploitation of natural resources, even a small photovoltaic power station can be maintained for users with limited power resources. Solar photovoltaic power generation is not only very convenient to use, but also more affordable than other new energy sources, while avoiding the inconvenience caused by power outages. It is a very good choice for everyone to save electricity and support for more energy saving and environmental protection.
