Ecuador

Ecuador solar market outlook

Ecuador’s installed solar capacity stood at 28 Megawatts by the end of 2019. One year down the line, the government of Ecuador has implemented new solar projects. One of these projects worth mentioning is the El Aromo photovoltaic energy project expected to cover 2.9 km2 of land.

According to pundits, the El Aromo project ushers in an era of prosperity for Ecuador’s nascent solar market. The government of Ecuador plans to achieve an overall installed capacity of 4 Gigawatts by 2030. So, the project is the first of a series of planned solar projects.

As a solar installer or professional, how do you decide whether a particular market is worth your time and money? Generally speaking, the availability of opportunities is the first thing you need to consider. Well, I can assure you that there is no shortage of prospects in Ecuador’s nascent solar market. With a little wisdom, business acumen and luck, you can land the next big solar project in Ecuador.

Ecuador’s solar equipment production and supply capacity

Even though Ecuador’s solar market is still young, it enjoys the services of several equipment manufacturers and suppliers. These manufacturers specialize in producing many types of equipment, including batteries, solar panels and inverters, to name a few. Do you want an equipment supplier for your next project?

Well, you are in the right place. Solarfeeds.com is home to some of the world’s leading equipment suppliers. Rather than moving around requesting quotes, visit our inquiry page and place your request.

Reliability of ports and logistics services in Ecuador

Ecuador boasts ten major ports that allow you to receive equipment from any solar market worldwide if needed. The country is also gifted with a highly professional and reliable logistics and forwarding services sector. Consequently, you can quickly receive your equipment from the port and transport them to the project site in time.  

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.
