What do people who have installed a solar power system say about it?

To help you better understand and avoid misconceptions about solar energy, we reviewed and analyzed the results of 1000 survey samples.

We asked solar power users what factors they value and care the most when deciding to install a system. On the other hand, two main “barriers" issues affecting their pre-installation considerations are the cost of installing solar power and the lack of information about this model.

Participants' answers will be according to 5 levels: Extremely interested - Interested - Normal - Not interested - Not at all.

The primary concern about installing a solar power system is the investment cost. 53% of the respondents to this survey said that installation cost is the highest concern (extremely concerned), while only 5% of people say they don't care about cost at all (didn't even think about it).

Although there is a relatively high initial investment, the benefits that come from saving on monthly and continuous electricity bill costs for decades are truly remarkable. Over time, this investment will be paid back within 5-7 years and the homeowner begins to profit on each other after that. In addition, with the policy of purchasing excess solar power of the State of Vietnam, it will be more optimal for household / business owners in terms of finance.

Because with each solar project, the investor only costs almost an initial cost and depends on your installation needs. A clear plan and careful calculation of the initial costs will allow you to completely determine whether you will recover that amount quickly or slowly and from when you will be "harvested" profits.

Another major concern of respondents to this survey was the lack of information about the solar energy sector. Among the surveyed group, 61% said that the lack of information was at the level of extreme concern and concern. Finding information and knowledge to plan the installation of a solar power system can seem quite difficult for newcomers, so this combined with the high cost has inadvertently been a barrier to discourage people from thinking about it. to solar power installation.

However, if you know Givasolar.com.vn, then surely you will not face the problem of lack of information about solar energy anymore, because we understand that well and have published a lot of quality articles. The volume contains the necessary and detailed information about the installation of a solar power system.

We asked people how long they think it will take to pay back their investment and start making profits from their system. In which, 51% of respondents said that it takes 3-5 years on average, 21% think that it can take up to 8 years to see a return on their investment.

In fact, the majority of grid-tied solar PV systems will pay off within a period of 5-7 years.

An interesting and quite common misconception about solar energy that we discovered in this study is that up to 50% of respondents believe that solar panels will not suitable for some climates. 33% of respondents are unknown.

Although the number of peak hours of sunshine will vary depending on the geographical location in the provinces, even in cold or hot climates, it is possible to collect solar energy and the difference between regions will not be too much. high. You can refer to the solar radiation map in Vietnam to understand the average number of sunny hours where you live.

In addition, depending on geographical location, there are many ways to help you maximize the efficiency of solar panels such as choosing the right high-end panels, choosing a good installation company. , periodic cleaning plan…

Another misconception is that cleaning and maintaining photovoltaic panels is routine and very strenuous work.

In our study, 35% of survey participants thought that the panels needed to be cleaned monthly and 18% thought they needed to be cleaned weekly.

Speaking of maintenance, 48% think the maintenance of the system is normal and only 10% think the maintenance is extremely difficult.

In fact, the cleaning and maintenance of solar panels is not too complicated. Of course, owners want the system to be clean all the time and always take special care of this to make sure everything is still working properly, so when some homeowners are a bit sensitive and worried worrying too much about this.

These two system configurations always exist side-by-side, which means that each of these system types has its own strengths. Many people do not really understand the benefits of these two system configurations, so they may accidentally choose the wrong type and lead to not meeting their true desires.

When it comes to grid-tied systems, the biggest advantage of this type is that it connects to the national grid, which can directly store solar power on it, can sell excess electricity, and can buy more if solar power output is not enough. it's not enough (in rainy days). What is especially important that people care about is the cheaper cost of installing a grid-tied solar power system because there is no need for expensive storage batteries.

On the other hand, the stand-alone system has a much higher installation cost because the system is not connected to the grid, so additional electricity storage batteries will be needed and the cost of solar batteries is also quite high. (equivalent to a solar cell). In turn, stand-alone solar power systems do not have to depend on the grid, you can install the system even in places where there is "no poles", you have complete control over usage and distribution. power generated by your system.

We also asked survey participants for their views on the environmental impact of solar cells as they reach their end of life. There are about 19% that waste from expired solar cells is harmful to the environment, 37% of respondents are not sure. Let Givasolar.com.vn analyze this issue.

Although the panels are guaranteed by manufacturers to last for about 25 years (performance warranty period), they can actually last much longer than that time, possibly up to 30-35 years.

Currently, there are also companies in Europe that specialize in handling and recycling expired solar panels. Photovoltaic panel recycling technologies are being developed by European countries better in terms of efficiency as well as cost optimization in the future.
