Honduras

Solar Market Outlook in Honduras

Honduras is emerging as the first major success story in Central America’s solar energy market. In fact, it earns the distinction as the first one in the region to attain 10% solar production in its energy industry.

In 2016, the state power energy company ENEE cited that 10.2% of the nation’s electrical system was generated from solar sources, specifically through PV power plants. This is a major breakthrough since Honduras becomes the first non-island nation to exceed the 10% mark in terms of solar energy production.

Honduras also leads other Central American nations in terms of the amount of installed PV capacity and is only second to Chile in all of Latin America. This energy revolution is spurring more development in Honduras and there are many investors hoping to take advantage of the photovoltaic boom in the country. With that said, the private sector has a lot to contribute to the growth of the solar energy market, especially after one plastic recycling company decided to install its solar panels to generate its own electricity. 

The forecast is good for the country as solar energy experts believe that the current growth rate is only going to attract more solar investors and manufacturers to the country. Even though the private sector is getting a lot of recognition for this growth, these results are also part of the decades-long effort by the government to push the utilization of renewable energy sources. 

Solar Energy Equipment Supply Capacity in Honduras

As one of the leaders in Central America’s drive to promote solar energy, there are a variety of options when it comes to solar energy equipment suppliers in Honduras. 

Even then, there are plenty of options for those who wish to import solar energy equipment, components, and other parts for PV and other solar installations.

Top 6 Major Seaports & Logistics in Honduras

The logistics and goods handling capability of Honduras is quite impressive. It has plenty of domestic and international seaports that facilitate transport of essential goods and solar equipment for those who are interested.

These top seaports are as follows:

  • Port of Puerto Cortes,
  • Port of Tela,
  • Port of Puerto Castilla,
  • Port of La Ceiba,
  • Port of San Lorenzo
  • Port of Puerto Coxen Hole.

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.
