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).
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.
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.
Solar Market Outlook in France
The solar market in France is characterized by ambitious targets and innovative solutions. The country has been one of the major proponents of solar energy in Europe and this is made possible by the strong policies in place.
In 2020, France crossed the significant threshold capacity of 10 GW installed. This brings the country to its goal of 20.1 GW solar capacity by the year 2023. This goal is established alongside the Multi-Annual Energy Programme.
Despite the impact of the pandemic, the solar market in France remains steadfast in its commitment to become the primary source of renewable energy source. France was able to produce 7.6 TWh of solar from January to June 2021. This was a significant growth from the 6.8 TWh power that was produced in the same period of 2020.
The French Renewable Energy Trade Association continues to push the country’s solar market potential and it has received a lot of support from the French national government.
Solar Energy Manufacturers in France
There is no shortage of manufacturers and companies that are dedicated to providing technological and innovative solutions to more French households and commercial spaces. This gives the market massive growth potential.
The vast amount of options for solar energy manufacturers in France has contributed to a growth in the solar market that the country has not experienced before.
Ports and logistics in France
There are a wide array of major sea ports and logistic companies operating in France. This is good news for residential and commercial properties that are looking to switch to solar energy.
There are 10 major ports in France and Marseille Fos Port is the main maritime port. This port handles goods and passengers with an average traffic of 88 million tons.
Solar Product Manufacturers in France
The production of solar products continues to see tremendous growth over the past decade in France. There are several options for consumers and it’s not just limited to solar panel installations.
Solar manufacturing in France includes solar water heating components, photovoltaic systems, solar roofing systems, indoor solar cells, and more.
