Rapid Shutdowns

Rapid Shutdown

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.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

Finland

The state of Finland’s solar market

Anybody can easily assume that solar is not a feasible option in Finland because of Northern Europe’s climatic conditions. Surprisingly, the country is keen to develop its solar capacity albeit the less favorable climatic challenges. Over the last couple of years, the Finnish government has been working to build its renewable energy capacity. So, that is the current state of Finland’s solar market?

Well, the latest statistics reveal that Finland had an installed solar capacity of 214 Megawatts by the end of 2019. Residential installations account for 45% of the cumulative installed capacity and the rest is distributed amongst commercial and industrial installations. According to recent statistics, solar is the second least costly option for electricity generation. This is the primary reason for the solar market’s continued growth.

Currently, the Finnish solar market is ripe with opportunities for solar installers and other photovoltaic professionals. Are you one of them? If the answer is yes, you stand a chance of reaping big in Finland with a little determination and unrivaled expertise.

Solar equipment production and supply capacity in Finland

Generally speaking, Finland is a net-importer of solar equipment. Solar installers and other photovoltaic professionals mostly import equipment from Asian markets. Nevertheless, there is some module manufacturing capacity in Finland. Solarfeeds has got you covered if you need a reliable supplier that can meet your project needs.

Essentially speaking, we connect you to leading solar equipment suppliers. All you need to do is go to our inquiry page and send us a request for quotes. That is pretty convenient and time-saving, right?

Major Ports and logistics services in Finland

As I mentioned earlier, Finland is largely a net-importer of solar equipment. The country’s advanced ports and reliable logistics and forwarding services often simplify the importation process. Here are some seaports that are you should know;

•  Port of Hamina
•  Port of Jakobstad
•  Port of Helsinki
•  Port of Oulu
•  Port of Imatra
•  Port of Rauma
•  Port of Mustola
•  Port of Kristinestad
