Photovoltaic solar power generation has the following advantages:
1. Clean and Renewable: Photovoltaic solar power generation has no direct emissions, produces no air pollution or greenhouse gases, and is environmentally friendly. Solar energy is a renewable energy source. Sunlight still exists and energy is sustainable.
2. Extensive Resources: Solar energy is one of the most abundant energy resources in the world. Sunlight is omnipresent and can be received almost anywhere, making it widely available.
3. Long-term economic benefits: Once the solar PV system is installed, the solar energy itself is free and there is no need to continue purchasing fuel. Photovoltaic systems have a long lifespan and have a stable and predictable impact on electricity costs, reducingthe risk of dependence on energy prices.
4. Distributed Energy Generation: Solar PV systems can be installed on the roofs of various buildings or open spaces and have the potential to produce distributed energy. This distributed generation approach reduces transmission losses and provides a more reliable energy supply.
5. Reduced dependence on the power grid: Solar PV systems can produce electricity independently, reducing dependence on traditional power grids. Solar PV systems can provide reliable power supply in some remote areas or in times of disaster.
6. Potential added value: Solar PV systems can also be combined with energy storage technology to store excess electricity for use at night or on cloudy days.In addition, photovoltaic solar systems can be used within a building to insulate, protect the roof and beautify the environment.
In summary, solar photovoltaic power generation has multiple advantages such as cleanliness, renewable nature, extensive resources, economic benefits and distributed power generation, and is an important sustainable energy.
First of all, photovoltaic solar is not a scam, it is real clean energy. However, the solar photovoltaic market has been relatively chaotic in recent years, and many people have been led. lost. The reason why solar energy has developed rapidly in the past ten years must be that there are some advantages. The biggest advantage is that after installing photovoltaic solar energy, you can save costselectricity, and you can even save some electricity. and connect it to the network to earn money. And judging from the current situation, many people will benefit from installing solar PV, especially those who have many household appliances at home. Installing solar PV can indeed save a lot of money, and some can save hundreds of dollars per person. year, you can even save thousands of dollars. So since there are benefits to solar PV, why do many people continue to say it's a scam? This may have a lot to do with certain companies that install solar. Photovoltaic solar energy is very popular. Many companies have entered this industry one after another in order to conquer moreage of markets, some companies even make various promises without conscience. Residents believe solar PV is a scam. This chaos is mainly reflected in several aspects.
First, the production of photovoltaic power has not achieved the expected goal.In order to sell solar photovoltaic power, some sellers can blow solar power into the sky and talk about various benefits to excite residents. For example, some vendors told residents that spending about 20,000 yuan to install a 5-kilowatt solar photovoltaic system could produce 20 kilowatt-hours of electricity per day, which is equivalent to about 7,000 kilowatt-hours of electricity per year .Among these 7,000 kilowatt hours of electricity, if you deduct 1,000 kilowatt hours of your own electricity, there will be at least 6,000 kilowatt hours of electricity that can be connected to the rnetwork to earn money. If calculated at 0.6 yuan per hour. per kilowatt hour of electricity, you can earn 3,600 yuan per year. This way, you can earn 3,600 yuan in 5-8 years. Once your capital is recovered, you can simply sit back and make money. But when these sellers present services to residents, they are actually following the most ideal state, that is, the theoretical value without taking into account weather conditions or photovoltaic decline.
However, solar PV will face large variables in the actual operation process, especially the impact on weather. For example, photovoltaic solar energy generates very little energy on rainy days, so on average. , Annual electricity production is not as ideal as these solar PV sellers claim. Another reason is that photovoltaic solar energy continues todecline as its lifespan continues to increase. After the decline, electricity production will continue to decline. Finally, after considering various factors, after several years of settlement, residents found that they were promised to earn more than 3,600 yuan a year, but in the end they only earned more than 1,000 yuan , or even a few hundred yuan per year. , many people felt like they had been cheated. More importantly, many places have received solar PV subsidies in recent years, ranging from 0.2 yuan to 0.4 yuan per kilowatt hour of electricity. However, over the past two years, many places have slowly reduced the intensity of solar PV subsidies. , and even some local governments have canceled it, and as a result, the sales price of grid-connected solar PV has dropped significantly. Currently,the selling price of grid-connected power generation in some places is only about 0.35 yuan per kilowatt. hour, which means the income is even lower. For this reason, many people feel like they have been deceived.
Second, some sellers deceive residents into applying for a loan under the pretext that it is free.The reason why many people think that solar PV is a scam is that, in addition to the unsatisfactory electricity production that we mentioned earlier, another very important reason is that many people are tricked into taking out loans to install solar energy. Some solar companies go to rural areas to promote their products, and their first words are worth more than their songs. They say they will install solar energy for these villagers for free and that theywill only have to use the money earned from electricity production to pay. several times. But subsequently, many people's photovoltaic power generation did not reach the expected targets, and the money from the sale of electricity was not enough to repay the monthly payment. Only then did many people realize that they had been deceived. by these people to apply for loans. Once you apply for a loan, it has nothing to do with how much electricity your solar panels generate. Regardless of how much electricity your solar panels can produce, you must repay the loan as normal. If you fail to repay the loan, your credit will be paid off. be affected and various penalties will be incurred. In many places, villagers have installed too much solar photovoltaic energy has led to debt, and it is precisely because ofThis makes many people feel cheated.
Third, subsequent maintenance costs are relatively high.When many solar PV companies install solar, they claim that their products have a long lifespan and low maintenance costs. Some companies even claim that they do not require maintenance for 20 years. But once installed, they don't care at all. If the solar power fails or there is a lot of dust, the villagers will have to spend their own money for maintenance, and the cost of this maintenance is not low. This is precisely because there are various problems during and after the installation of solar energy. Many solar PV companies have even gone bankrupt. So it's normal to think that you. I've been cheated when you have problems you can't express.
