By the end of 2020, Vietnam has had more than 100,000,000 rooftop solar power system projects connected to the national power system, with a total installed capacity of up to 9,300,000Mwp. It is clear that the solar power system (also known as the solar system) brings great benefits to businesses such as helping to reduce electricity costs in proportion to the amount of electricity generated, supplied to the building or reduced. greenhouse gas emissions. However, due to the uncertain nature and rapid development in a short time, a number of solar power systems have not been fully invested, synchronous and sustainable, especially in the work of ensuring electricity safety. fire safety.
In fact, in recent years, many projects that do not ensure fire protection have encountered unfortunate incidents and caused significant loss of life and equipment for investors and roof rental businesses. . According to experts and operators with many years of experience in the solar industry, for solar power projects, especially rooftop solar power, the most difficult part is operation and management. monitor system performance.
In fact, problems have been recorded when installing and operating solar systems; which mainly revolves around 5 outstanding issues:
- First: Local heating problem on solar panels
- Second: The problem of cos, rack, mc4
- 3rd: Battery string reverse polarity problem
- Fourth: The problem of lightning strikes
- 5th: DC side short circuit problem
So, what is the solution to optimize the investment efficiency of the solar power system for businesses?
To get an investment plan for a smart, modern and efficient solar power system, typically rooftop solar power, in addition to choosing the type of solar power system, the layout, installation as well as Reputable contractors are The prevention of fire and explosion risks is an urgent matter, especially with large capacity investment enterprises.
Understanding that, FOCUS SOLAR research and provide Solution to prevent fire and explosion of solar system. With a background as an experienced EPC contractor in the field of consulting, equipment supply and installation, maintenance and operation of solar power systems with measurement and calibration methods according to international regulations , we - Focus Smart Technology Solutions Joint Stock Company - are proud to be one of the leading enterprises in providing Solar system fire prevention solutions.
Some measures to prevent fire and explosion of solar power systems:
Select suitable and reputable materials, with a clear certificate of origin; using modern and advanced technology lines to improve safety and minimize the risk of fire and explosion; at the same time, making panels smarter, generate more electricity, use it more efficiently and deliver greater benefits.
- Choose a reputable, experienced solar installer.
- Set set inverter, the center console in a cool, dry place, avoid contact with flammable items, closed room.
- The electrical cabinet must be protected by specialized aptomats, the power sources must ensure that there is correct and sufficient lightning protection system on the line.
- Connectors must be sealed, press the cos end before operation.
- Safe grounding system, separate from the lightning protection grounding system of families, factories, buildings... do not directly connect the grounding system to the lightning protection system together, avoiding the situation of high lightning current causing the battery and inverter to explode.
- Maintenance and periodic maintenance of the system to check the connections, the quality of the auxiliary equipment in the solar energy system, to ensure the standard operation.
