Solar Market Outlook in Czech Republic

In the 2021 Solar Conference, Industry and Trade Minister Karel Havlicek reveals that the future is bright for the solar energy market in Czech Republic. The country plans to move away from coal as its main power source and they are looking at renewable sources as a viable option for replacement.

It’s not just the government that is pushing for solar energy, the private sector also agrees on the importance of switching to solar in Czech Republic. This is fueled by the European Union’s green energy targets and the country believes that the solar industry is poised to play a vital role in meeting that target.

In Czech Republic, in particular, the solar industry is experiencing a massive growth period. There are more households and businesses that have installed solar roof panels. 

Czech Republic held a 19% share in renewable energy for electricity generation. They are expected to increase the share to 22% by 2030. 

Solar Energy Supply Capacity in Czech Republic

There is a long list of solar energy equipment manufacturers and suppliers in Czech Republic. This makes it possible for the country to have a high share of the renewable energy market in Europe and worldwide. 

In fact, some of the biggest manufacturers and producers of solar panels and technology are serving the Czech market.

Top 8 Major Seaports & its Logistics

Czech Republic is a land-locked country. However, it has sufficient access to the sea through its ports that facilitate logistics companies moving goods and other equipment. 

The main ports in Czech Republic are: 

  • Decin Port
  • Usti Nad Labem Port
  • Port Praha Radotin
  • Port of Kolin
  • Port Melnik

When transporting solar equipment from top manufacturers in Czech Republic and other parts of the world, there are also several logistics companies to help with this such as the following:

  • Vit Logistics
  • Rail Cargo Logistics
  • GEFCO Trucking Company

Electric Breaker used for below projects in Czech Republic

Electric Breaker

Electric Breakers

When installing a solar panel system, you have to be familiar with the electric breakers and how it works with a solar PV system to avoid future electric problems. The electric breaker is one of the main components of a solar power system that provides safety mechanisms. If ever the electrical wiring of your system has too much current flowing through it, these breakers can easily cut the power until your solar installer can fix the system’s problem. 

For today’s article, we will discuss electric breakers and their function in solar photovoltaic systems.

What is an Electric Breaker?

An electric or circuit breaker is an electrical switch designed to protect electrical circuits from damage caused by overloading of current or a short circuit. The basic function of an electric breaker is to prevent the current flow once protective relays detect a fault in the system. 

Although it is frequently interchanged with a fuse, which is the simplest Over Current Protection device (OCPD) in electrical circuits, a circuit breaker, is a much-evolved type of device that interrupts the current flow. The main difference between the two is electric breaker is resettable and the fuse is not. The fuse sacrifices itself while protecting the system to overheat, while the circuit breaker can withstand hundreds and thousands of operations. Another difference is that electric breakers are used with relatively higher currents. 

Components of Circuit Breaker

A circuit breaker system is composed of three parts. These three components are the sensing system, relay, and the combination of contacts and the contact actuator. A sensing system is responsible for detecting an overload situation, while a relay is responsible for transferring the information to the switching arrangement, and the combination of contacts and the contact actuator. This electric arrangement is usually observed in power transmission and distribution networks dealing with very high currents, voltages, and powers. 

Circuit Breakers Calculation in Solar Panel Systems

When connecting circuit breakers to the PV system, you have to follow the recommended calculations to avoid future problems and damage to the entire system. The recommendations for using overcurrent protection devices including circuit breakers in solar modules against overloading conditions are given in IEC 60269-6 (volume 6 of IEC 60269-6) and also UL 248-19. 

For circuit breakers, IEC recommends a 20% and 25% margin in voltage and overload current. Most of the time, the ratings are specified by the solar manufacturers at given ambient conditions. If the temperatures exceed this given value, derating must be applied according to the manufacturer’s specifications. 

When it comes to breaker sizes for solar panels, NEC requires the breakers to be sized at 125% of the inverter’s rated output. So a 7680W inverter that outputs 240V, outputs 32A (7680W ÷ 240V = 32A). That requires a 40A breaker (32A x 125% = 40A).

Final Thoughts

If you owned a solar panel system at home,  you have to understand how circuit breakers work to prevent catching fires at home. These devices are one of the major components of the PV solar system as they protect the system wiring from getting too hot and accidentally catch fire if short circuits occurred. Thus, understanding the breaker itself and its proper calculations in the PV system should be done.

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.
