Solar Market Outlook in Monaco
Monaco and its government is taking its environmental responsibilities seriously and they are taking measures to achieve its 2030 target of reaching 50% less GHG emissions. This figure is way more ambitious than the EU target that was cited in the Paris Agreement. In addition to that, Monaco has also set an ambitious target for carbon neutrality by 2050.
To make this happen, they have turned to renewable energy sources such as solar power. The National Green Fund is an initiative that was started to provide financial support for the country’s long-term climate action. Monaco is also investing in solar power through enabling the purchase of electric power plants that were powered by renewables.
Since 2005, Monaco has remained steadfast in its commitment to undergo sustainable development. It started with the installation of solar roofs in residential and commercial properties. Aside from installing solar panels on the roofs, Monaco has also used heat pumps in order to generate energy since 1960. Recently, the government is looking at utilizing tidal energy for power generation, too.
As of today, renewable energy is responsible for 24% of Monaco’s energy consumption and the government is committed to increasing that in the years to come.
Solar Energy Equipment Supply Capacity in Monaco
There is an abundance of solar roof panel suppliers and distributors in Monaco. For those looking for utility scale installations, you can also turn to global and online distributors.
Top 8 Major Seaports & Logistics in Monaco
The ports in Monaco play a vital role in the economy especially in trade and logistics. You can transport solar power equipment via the primary seaports in the country such as
- Port Hercule,
- Port Cap d’Ail,
- Port Fontvieille.
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.
