First, let's look at the advantages of assembling photovoltaic power generation devices. In our area, most houses are essentially small bungalows. The advantage of small bungalows is that they can dry corn, wheat and other grains on the roof, as every household used to hoard grains. But now people have lost the habit of hoarding food and the roofs are vacant. Therefore, when photovoltaic power generation personnel came to promote it, most people thought that the roofs were unused and they might as well assemble photovoltaic power. generation devices, so you can also use the vacant roof to make money, why not do it. Therefore, the advantage of assembling photovoltaic power generation devices on the roof is that the vacant roof is no longer vacant and there isalso has a good rent to collect each year.
Let's look at the disadvantages of installing photovoltaic power generation on the roof. The first is that the probability of water infiltration into the house increases. When assembling photovoltaic power generation devices on the roof, you must use screws and other tools to attach the photovoltaic modules to the roof. This will damage the original waterproof layer of the house. Although the staff waterproofs the villagers again after assembly, The actual effect of waterproofing again is much less than the first time, so the probability of water leakage in the house will increase.
In addition, some people took advantage of flaws in the system. In fact, there are subsidies for the assembly of photovoltaic power generation devices in rural areas, and the amount of subsidies is very large. However, these peopledo not return subsidy money to villagers. They often keep a large part of it themselves and only. give a small share to the villagers. In addition, when assembling the photovoltaic power generation devices, the villagers' unfamiliarity with photovoltaic power generation will be used to replace good quality products with poor ones. quality without authorization. These people no longer provide after-sales maintenance services. after receiving the grant money, when the villagers encounter after-sales problems, they can't find anyone and can only handle the mess themselves.
In short, there are advantages and disadvantages to assembling photovoltaic power generation devices on rural roofs. Home is the warmest place for the whole family. We must not put ourselves in a desperate situation because of some immeditorials.
The lifespan of a rooftop photovoltaic energy production system is generally between 20 and 30 years. The specific lifespan depends on many factors, including system quality, design and installation. photovoltaic modules. Quality, operation and maintenance methods, etc.
Solar PV modules generally have a long lifespan, with most manufacturers offering a 25-year linear power warranty. This means that over a period of 25 years, the power output of photovoltaic modules will not drop below a certain percentage. Generally speaking, the power attenuation rate of photovoltaic modules is about 0.5% to 1% per year.

In addition to photovoltaic modules, other components such as inverters, brackets and cables will also affect the service life of the system.Inverters typically have a lifespan of 10 to 15 years, and brackets and cables are in the same range.
In order to ensure the long-term operation of rooftop photovoltaic power generation systems and maximize the benefits of electricity generation, regular inspection, maintenance and cleaning are necessary. Check the working status of the system regularly, detect and repair faults timely, and extend the service life of the system.
In short, the lifespan of a rooftop photovoltaic power generation system is generally between 20 and 30 years, but regular maintenance and upkeep are necessary to ensure the normal operation of the system and maximize the benefits of electricity generation.
