Is the rooftop solar photovoltaic power station reliable? You will understand after reading these!

       Many behaviors nowadays did not exist a few years ago. For example, when you wake up in the morning, open WeChat to check your Moments, walk to the subway station to see how many steps the smart bracelet has memorized, open Meituan's takeaway when you are hungry, and open the APP in bed at night to see the power generation and power generation How much money did you make...

With the acceleration of the energy democratization process, household solar photovoltaic has gradually entered the homes of ordinary people, and the installation of home solar photovoltaic is becoming a way of life and money for ordinary people.

According to the various questions raised by everyone on the Internet, the editor summarizes the following related to photovoltaics, hoping to answer everyone's doubts.

First of all, you need to get out of these three misunderstandings

☞When the common people install it, the subsidy will be gone

☞ Photovoltaic panels are replaced every two or three years! the cost is too high! There will be no power generation in two years!

☞ This thing is afraid of hail! It rots as soon as the wind blows!

Dismantling 1: Once the people install it, the subsidy will be gone

Starting from June 1, 2020, the national subsidy for ordinary household photovoltaic power plants has been reduced from 0.18 yuan/kWh last year to 0.08 yuan/kWh, and many people have issued the above “complaints”.

In fact, changes in subsidies will not affect users who have installed photovoltaic power plants. The subsidy policy will be implemented in which year the power station is connected to the grid.

In addition, it should be noted that the subsidy is reduced because the cost of photovoltaic power plants is declining, and the benefits of installing photovoltaic power plants in the future are still considerable.

Some friends said that after installing photovoltaic power plants, they did not receive power generation subsidies and electricity sales revenues, and they would be angry and said "photovoltaic power generation is a lie." In fact, you have not received the money now, maybe it is just that the settlement has not yet arrived. .

The settlement cycle of subsidies and on-grid electricity charges varies from place to place. Some areas are settled on a monthly basis, while others are settled on a yearly basis. The specific settlement cycle is indicated in the power purchase contract. (When the power station is connected to the grid, the grid company will sign an electricity purchase contract with the owner)

If your subsidy is in arrears, you can call the State Grid 95598 or the National Energy Administration supervision telephone 12398 to file a complaint, and it will be properly resolved.

Dismantling 2: The installation cost is too high. The photovoltaic panels are replaced every two or three years, and ordinary people can't install it.

In fact, photovoltaic power plants are divided into off-grid systems and grid-connected systems. The common ones are grid-connected systems and systems that are integrated into the grid. The electricity generated by photovoltaics can be uploaded to the grid without the need to install batteries. The off-grid system only needs batteries. The electricity generated by photovoltaic power plants during the day is stored in the batteries for emergencies. This system is often used in applications such as electricity-free areas, remote mountainous areas, islands, and street lights.

At present, the module warranty period of regular photovoltaic manufacturers is 10 years, and the guarantee of power generation efficiency is 25 years. The inverter warranty period is 5 years, and paid service can be provided after 5 years. If you choose a regular manufacturer, there will be no problem of replacing the battery every two to three years.

With the upgrading of the industry and the advancement of technology, the cost of photovoltaic power plants has been declining, but the information of many people is still a few years ago, thinking that photovoltaic power plants are luxury goods, in fact, photovoltaic power generation has long entered ordinary people's homes.

Dismantling 3: This thing is afraid of strong winds and hail, and the maintenance cost is very high.

Many people feel that the glass and frame of photovoltaic power plants are afraid of hail and strong winds. In fact, qualified photovoltaic modules have undergone rigorous testing before leaving the factory, including hail test and mechanical load test (including wind pressure test), which can withstand severe weather such as hail and strong winds. Professional installers will carry out reasonable design and installation according to the local climate during installation. There is no problem for photovoltaic power plants to resist 8-10 strong winds.

A set of qualified photovoltaic power plants can be used for more than 25 years. Regular manufacturers will also provide warranty, and repair costs will hardly be incurred in the later period. The power generation of photovoltaic modules is attenuated, but regular manufacturers will provide power generation warranty for their photovoltaic modules. Within 20 years The power generation attenuation will not exceed 20% of the design power.
