Can solar power plant Withstand Category 17 Typhoon(Super Typhoon Noru) in Philippines?

The No. 16 typhoon “Super Typhoon Noru of this year rapidly strengthened from a strong tropical storm to a super strong typhoon last night. At 5 o’clock this morning (25th), its center is located on the ocean about 350 kilometers east of Manila, Philippines, which is 15.1 degrees north latitude and 124.2 degrees east longitude. The maximum wind near the center is above 17 degrees (62 meters/second).

It is expected to move to the west at around 20 kilometers per hour and make landfall on the Philippine island of Luzon (58-65 meters per second, Category 17 or higher, super typhoon) this evening and overnight.

Affected by cold air and “the deer”, 25, 08 up to 26, 08 in the Taiwan strait, the bashi channel, northern south China sea and the Middle East, the dongsha islands, xisha islands, zhongsha islands and the waters near huangyan island have 6-7 level wind, gust 8-9 level, including the south China sea in the east sea, near the huangyan island sea wind up to 8-12 level, Wind gusts of magnitude 13-14, with winds of magnitude 13-17 and gusts of magnitude 17 or above in the waters and areas near the center of the typhoon.

For users who have installed solar PV power stations, the safety of PV power stations should be focused on when typhoon strikes.The wind resistance of PV power station is mostly determined by photovoltaic support and counterweight. The solar photovoltaic bracket is a special bracket designed for placing, installing and fixing the solar panel in the solar photovoltaic power generation system, which is generally made of aluminum alloy, carbon steel and stainless steel. Theoretically, the maximum wind resistance of the solar support is 216 km/h (typhoon of level 17), and the maximum wind resistance of the solar tracking support is 150 km/h (typhoon of level 13). The aluminum frame and protective tempered glass used by our 460W solar panel enable this PV module to withstand the load of 5400 pa, thus resisting the worst weather. Generally speaking, the PV power station installed in a standard way can ensure that it can withstand the strong wind of 8 to 10 levels, withstand the damage caused by rainstorm, corrosion and other factors, and operate safely and stably for more than 25 years.

Although the support and counterweight are the key factors affecting the wind resistance of the photovoltaic power station, the layout scheme, product quality, installation angle and other factors of the photovoltaic power station cannot be ignored. When the typhoon strikes, the PV power station needs to be prepared for reinforcement before the typhoon comes, otherwise accidents are likely to occur. Before a strong typhoon comes, the photovoltaic power station shall be thoroughly and carefully inspected, and preventive measures shall be taken in time.

It is easy to solve these problems, that is, to find a reliable brand of photovoltaic power station. They will take wind resistance, snow pressure resistance and other factors into account according to the local actual situation, and design the optimal layout scheme, angle and counterweight. During construction, wind resistance can be guaranteed without cutting corners.

If the PV power station is not installed with protective support, the windproof tie rod shall be installed and fastened to prevent the PV support from loosening due to strong wind. If the photovoltaic power station is installed on the ground, the ground anchors on both sides of the array shall be compacted. If the photovoltaic power station is installed on the roof, the tandem modules on the windward side can be bundled and fixed with iron wires. Sand bags can be properly used to increase the counterweight of the power station to avoid instability of the power station with small fixed piers.

Typhoons often bring heavy rainfall and flood disasters. Check the insulation and sealing of all electrical equipment in the photovoltaic power station, and check whether the AC and DC terminals are connected normally. If the relevant equipment is installed at a low place, it shall be removed in time and placed at a high place. If necessary, the operator shall be contacted in time to reinforce and maintain the power station.

You can consider purchasing photovoltaic insurance, which can make up for the accidental losses caused by natural disasters or man-made theft of household photovoltaic systems within a certain range, and can reduce the investment risk of photovoltaic projects.

After the typhoon passes through the country, it is necessary to conduct a comprehensive inspection of the photovoltaic power station and deal with the damage, debris coverage and cracks in a timely manner so as not to affect the subsequent operation of the photovoltaic power station and affect the safety of the power station system.

The Philippine weather service has issued a wind signal five for Luzon, the highest warning level which marks Noru as a super typhoon.

Please keep safety.
