If you got your first solar panel system installed in your house, chances are you will see a box with an on/off switch that says “rapid shutdown.” But do you have any idea what does it mean or why is it important to know when installing a solar panel system at home?
In today’s article, we will provide you with an overview of rapid shutdown requirements, and everything you need to know about it.
What is Rapid Shutdown?
Rapid shutdown is an electrical safety regulation that requires every solar panel system to set the solar panel shut-off switch. The National Electrical Code (NEC) introduced it to the public in 2014 with the aim to provide a simple way for firefighters to quickly cut off the current in the DC conductors of the rooftop solar panel systems. It is basically set to make sure that the roof of a building is safe from fire. Usually, when the standard inverter of a solar system is switched off, the DC wiring, from the solar unit, still runs particularly when the sun is up.
Why is Rapid Shutdown Requirement Implemented?
The National Fire Protection Association (NFPA) provides rapid shutdown requirements and writes them to the NEC to ensure safety measures. Your home may not catch fire so you don’t have to worry about rapid shutdown functionality. However, if it accidentally happens, firefighters can easily use rapid shutdown solutions to de-energize your solar panel system.
Remember that simply turning off the solar inverter doesn’t shut down the unit. Turning it off may not power off some inverter setups, wires, and circuits, increasing the risk of electric shock. But if you have a rapid shutdown device, then you can easily power off the entire unit, reducing the electrical voltage of your solar panel system in less than a minute. Generally, the rapid shutdown code set the standard to quickly reduce the voltage of any conductors.
Is Rapid Shutdown Required?
Rapid shutdown is a safety measure of the National Electrical Code (NEC). The NEC releases a new or updated set of requirements for safe electrical systems every three consecutive years. Technically speaking, the rapid shutdown is not required everywhere in the United States, although it’s a good idea to install a solar panel system with a rapid shutdown switch.
Another important thing to note is the NEC is not federally mandated, so individual states can freely choose to follow and abide by the code within their time frame and discretion. Some states choose an independent, state-wide electrical code instead.
Should You Comply with the Rapid Shutdown Regulation?
Generally, solar power systems without rapid shutdown switches are not totally unsafe to first fire responders. If you have a solar power system installed before the implementation of the rapid shutdown, it is less likely to expose your building to more risk. As long as your solar installer is well-experienced with the job, you have nothing to worry about.
However, if you want to be safe and secured, and for your peace of mind, it’s certainly worthwhile to follow the rapid shutdown requirement. Most of the time your installers are highly educated when it comes to changing codes for your state. They also can design your solar power system that can easily comply with all rapid shutdown requirements.
Solar Products Distributors
Distributors are those companies working as big warehouses that served as the middlemen between the consumer/customer and the manufacturer. Typically, in distribution, a company is handling the sourcing, stocking and logistics but nowadays they are also helping manufacturers in product designing and solving other business conflicts.
Aside from other industries, distributors also play a vital role in the solar industry. Solar distributors become long-term partners of solar manufacturing companies and even solar contractors. They are not only serving as warehouse facilities but partners that also provide strategic solutions to help solar companies achieve their desired outcomes. Solar distributors assist solar manufacturing companies by storing. handling and shipping their solar products to their buyers. On the other hand, they help solar contractor companies in outsourcing high-quality solar products.
These solar distributors are the ones who deal with homeowners who want to go solar, businesses that work with the solar industry and solar installers who offer solar system services to both residential and commercial customers. But on top of that, the solar distributor’s main role is to maintain its commitment to outsourcing and handling high-quality products and delivering them to customers at a good value.
Up to these days, many solar distributors have been operating and helping many solar companies in distributing their products. So, if you are looking for the most trusted and reliable solar distributor, you can easily find one by checking out solar outsourcing companies that provide easy access to reliable information, news, data and a list of solar suppliers and distributors near you.

Solar Market Outlook in Taiwan
The Taiwanese solar energy sector is one of the rapidly growing industries in Asia. In 2021, it is targeting to achieve a growth of 1.5 to 1.7 GW of solar capacity. In order to meet this target growth rate, the Taiwanese government is accelerating its development efforts for the coming year.
The government of Taiwan is currently promoting its PV policy while also building construction timelines for ground-mounted projects. There are two areas that the Taiwanese solar PV market is focusing on: fishery-solar hybrid power stations and major electricity consumers. If plans push through, Taiwan is looking at a solar market future with a green energy certification scheme and feed-in tariff scheme in place.
The government of Taiwan took serious steps toward the start of its switch to solar and wind power at the start of 2020. However, it is still a long way to go before it can mitigate any losses incurred from the shutdown of coal plants. With the renewed focus on solar energy, the government expects that reliance on coal for energy production will drop from 44% to 37% in 2030. The economic leaders in Taiwan have previously set the target of 20 GW in solar energy production by 2025, although solar project managers are doubtful that they can hit this target.
Solar Energy Equipment Supply Capacity in Taiwan
Taiwan currently has a shortage of local solar equipment suppliers and manufacturers. However, there are several global suppliers and distributors to increase its solar installation capacity.
Top Major Seaports & Logistics in Taiwan
To facilitate ease of trade and transport of solar equipment in Taiwan, the following ports are open for trade and logistics activity:
- Port of Taipei,
- Port of Taichung,
- Port of Kaohsiung,
- Hualien Port,
- Port of Keelung,
- Mailiao Harbor.
