10 principles to ensure safety when installing rooftop solar power systems
(Baonghean.vn) - Realizing that the installation of rooftop solar panels is quite simple, some people now subjectively buy the system to install it themselves or hire an unqualified electrician to install it at home to save costs. However, due to not following the correct technical process, it has led to fire and damage to the equipment.
Solar power has just been applied in Nghe An area so it is quite new. However, due to the policies encouraging the use of rooftop solar power as well as the great efficiency it brings, the number of households in Nghe An installing the system is increasing.
Installing a solar power system seems quite simple, so now there are some households who arbitrarily buy the system and install it themselves or hire non-professional electricians to install it, with the aim of saving money.
However, rooftop solar power system is a high-tech product, not yet widely used, the power output is large, so it requires high skills, qualifications, and deep understanding to be able to install the system for safe operation.

Through an exchange with reporters, Mr. H. said that his family bought the solar power system, installed it themselves, and connected it for about a year now. His family does not know the cause of the fire because they do not know how the system works specifically, but only how to install it to make it work.

To better understand the issue of safe installation of rooftop solar power systems, we had a conversation with Mr. Pham Ngoc Truyen - Deputy Director of Hekinan Joint Stock Company (address 75, Ton That Tung, Vinh City). This is currently the leading unit in rooftop solar power systems in Nghe An area, currently constructing the largest rooftop solar power project in the province.
“The rooftop solar power system is a modern technology system, so it requires high technical factors in installation to ensure safety when putting the system into operation. The system also needs to be regularly maintained according to the manufacturer's regulations, which also requires good technique and deep expertise,” said Mr. Truyen.

According to Mr. Truyen, to safely and effectively install and operate a rooftop solar power system, the following 10 requirements must be met:
The first:Must survey houses, companies, factories… to see if the quality of electricity, transmission lines, and transformer stations are reasonable or not.
Monday:Must choose suitable and reputable materials on the market. Floating goods of unknown origin can make the system run unstable and also cause danger during operation.
Tuesday:You should choose a contractor with experience in solar power for installation.
Wednesday: If you install it yourself, you must have experience and in-depth knowledge of solar power as well as the state power grid.
Thursday:When installing a solar power system, you must choose the direction of the solar panels so that the working efficiency and performance of the panels are highest during the day.
Friday:The location of the inverter installation is very important. We should follow the instructions of the manufacturer and the distributor. The inverter should be installed in a dry, cool place; avoid contact with flammable objects and closed rooms.
Saturday:The electrical cabinet must be protected by specialized circuit breakers such as: Solar panels must be protected by specialized DC circuit breakers for solar systems. The grid must be protected by anti-shock circuit breakers. Power sources must have a surge protection system on the line.
Eighth:The connectors must be sealed with tape and crimped before operation.
Thursday:For solar power systems, there must be a safe grounding system. The working grounding system must be separate from the lightning protection grounding system of the family, factory, etc. Do not directly connect the grounding system with the lightning protection system to avoid the situation where high lightning current will damage the solar panels and inverter.
Thursday:Once the system is installed, there should be a regular maintenance and cleaning plan to keep the system operating at its best and with the highest efficiency.

“To fully and accurately carry out the above steps requires high technical skills. Therefore, our company always prioritizes ensuring the safety of the system as well as the operating process, so the unit regularly holds training sessions and conducts additional safety checks for all employees, especially technical staff; especially when new systems are launched” - Mr. Truyen added.
