Use solar power to supply daily household electricity; Grid-connected power generation, selling excess electricity to the state in exchange for income. Home solar power generation system saves money and is environmentally friendly, which makes many families eager to try.

But the ideal is always beautiful. The reality is that many people are deterred by their inner confusion and insecurity when facing the last step – installation.

Therefore, in order to solve your doubts, we have specially sorted out 9 core questions and corresponding answers about home solar power generation systems, hoping to let you put down the stones in your heart and let better clean energy enter everyone’s home at ease.

Question 1: will the community property agree to install in the urban villa?

The main reasons why the property in the villa community disagrees with the installation are as follows:

1. They don’t understand the whole business process and are afraid of making any mistakes;

2. Worry about damaging the overall beauty of the community.

As long as the roof is reasonably designed and installed and the photovoltaic power generation system is installed, the original house structure will not be affected and the surrounding environment will not be affected.

Therefore, if you want to install in an urban villa, you only need to reasonably communicate and explain with the property to let it understand the installation process and final effect. Generally, the property will agree to install.

Question 2: how to install a roof shared by dozens of families?

If you are a multi-story community user, because the roof of the multi-story community belongs to the collective ownership of the owners, if the owner on the top floor wants to install the photovoltaic power generation system, all the owners of the corridor need to sign and agree to install photovoltaic equipment on the top floor. Such installation can reasonably reduce the shared electricity charge of the community. However, the specific implementation needs to be implemented according to the actual situation.

Question 3: is the overall investment high? What are the benefits? How soon can I get back? Does the state have a loan policy?

Energy investment is an intensive investment. The early investment in photovoltaic power generation is large, and the system power generation cycle is 20 ~ 25 years. This part of the investment may be relatively high for many people, but the state will provide corresponding incentive policies to solve the problem of insufficient funds.

And from then on, you not only don’t have to pay the electricity bill but also the surplus electricity can be sold to the state to earn income. According to the data analysis, a 5kW photovoltaic power generation system can generate about 6500 ~ 7500 degrees of power a year, and will also receive state subsidies. Generally, the cost can be recovered in 5 ~ 6 years, and the static rate of return can be up to 20%.

Question 4: I heard that even with state subsidies, the later maintenance cost is also very high. Is it true?

The reason why the state provides subsidy policies is not only to vigorously support the promotion of photovoltaic but also to reduce the installation investment cost of ordinary families.

A set of photovoltaic power generation system can normally generate electricity for more than 25 years. If qualified products are strictly selected, high-quality system integrators can basically ensure that there is no additional maintenance cost in the later stage. At present, many families in various regions have been installed and used, and the daily power generation can be clearly seen through the monitoring system.

Question 5: how long is the service life of the photovoltaic power generation system?
At present, the power generation life of solar panels produced by qualified solar panel manufacturers is 25 years. If they are properly maintained, it is no problem that their life exceeds 30 years.

Question 6: what is the warranty period of solar products?

The core of the photovoltaic power generation system is solar panels. At present, most enterprises have a 10-year product warranty and a 25-year linear power guarantee for their solar panels.

Question 7: the sunshine time in the north is short. Is it not suitable for installation?

Different longitude and latitude regions have different irradiance. China is one of the countries rich in solar energy resources. The total area of the country is more than 2 / 3, the annual sunshine is more than 2000 hours, and the annual radiation is more than 5000mj / m2.

Northern China is a class II region (rich in resources), with annual radiation of 5400 ~ 6700mj / m2, which is suitable for the installation of a photovoltaic power generation system. You don’t have to worry.

Question 8: will the system be damaged in extreme weather?

At present, most brands of products can withstand general rainfall, snowfall, hail, and other bad weather without having a great impact on the performance of solar panels.

Secondly, it is recommended that the owner installing the photovoltaic power generation system purchase the corresponding power station insurance. In case of similar natural disasters, the insurance company can provide corresponding compensation services.

Question 9: where can I buy it?

Since the installation of a photovoltaic power generation system involves roof survey, design layout, scheme production, acceptance and grid connection, the more mature service mode is to select professional service providers for purchase.
