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.

What is Solar Energy in Germany?

Germany, despite being a sun-drenched country has been considered as one of the highest solar power outputs around the world and still possesses the most advanced and latest research about solar energy and has many new industry actors. Moreover, they’re expecting for the second wave of solar power expansion, which will soon bring success and progress for the solar technology’s full systemic integration.

For several years, Germany has been considered as the world’s top PV installer among other countries. At the end of the year 2016, Germany managed to build a total installed solar power capacity of 41.3 gigawatts (GW) which was behind China’s solar capacity.

Most solar power in Germany exclusively consists of photovoltaics (PV) systems only. Germany has only a little interest in concentrated solar power (CSP) for it does not use photovoltaics and this solar technology requires much higher solar insolation as compared to the PV system. However, there is still an experimental CSP-plant with 1.5 MW capacity which is being used solely for on-site engineering purposes only rather than for commercial electricity/power generation. This concentrated solar power is called the “Jülich Solar Tower” that is owned by the German Aerospace Center.

Moreover, in 2014, Germany managed to install about 1.5 million photovoltaic systems across the country which are ranging from small rooftop solar power systems to medium commercial and large utility-scale solar plants and farms. The largest solar farms of Germany are located in Neuhardenberg, Templin and Meuro with solar capacities of over 100 MW. Moreover, these PV technologies were accounted for an estimated 6.2 to 6.9 percent of Germany’s net electricity generation in the year 2016.

However, new installations of photovoltaic systems have slowed down steadily since the beginning of the year 2011. Also, it was estimated in the year 2017 that over 70 percent of the employment in the solar industry of the country have been lost in recent years. Solar power in Germany has gone through rough times since it has been started in the wake of Germany’s Renewable Energy Act in the year 2000. However, German companies quickly loomed to global leadership in solar power technology before a collapse in the solar industry happen and some of the companies were forced to hold their businesses.

Proponents from the Photovoltaic industry blamed the government for its lack of commitment in the said industry, while others point out that the loss of jobs in the solar sector is due to financial burden that was associated with the fast-paced launching and manufacturing of photovoltaics, which in their perspective was very unsustainable to the transition of renewable energies.

With all of these, still, the official governmental goal of Germany is to continuously improve and increase the contribution of renewable energy to the country’s overall electricity generation and consumption. By 2020, Germany is aiming for a long-term minimum target of 35 percent capacity, 50 percent by 2030 and around 80 percent power capacity by the end of 2050.

Currently, the country is significantly producing more electricity at specific times with high solar irradiation than the country’s needs, slowing down spot-market prices and exporting the country’s electricity surplus to nearby countries. In 2014, the record of exported electricity surplus reached almost 34 TWh. The decline of spot-prices in the market may raise the electricity prices for retail customers, as the expansion of the guaranteed feed-in tariff and spot-price increases as well.

As the combined share of fluctuating wind and solar energy is nearly achieving 17 percent of the national electricity mix, energy issues and problems are also being prevented and others becoming more manageable. This is because of the electrical grid adaptation, new grid-storage capacity construction, reduction of fossil fuels, altering of nuclear power plants and constructing a new generation of combined heat and power plants. Today, nuclear power and brown coal are the cheapest suppliers of electricity in Germany.
