Before choosing a solar inverter...

When our photovoltaic panels receive sunlight, electrons begin to move inside the solar cells, which produces direct current electricity. Circuits inside the photovoltaic cells collect that energy for us to use in our home.


This is where the solar inverter comes into play. Most homes use alternating current electricity, not direct current, so the energy produced by the solar panels is not useful by itself.


When the solar panels collect the sunlight and convert it into energy, it is sent to the inverter, which receives the DC electricity and converts it to AC power.


This is when the solar electricity can power appliances and electronics or, if we are producing more electricity than we need, store it in batteries or we could feed it into the grid.


The main functions of a solar inverter are...

Convert energy: The solar photovoltaic inverter converts direct current into alternating current, which is used by all electrical appliances.

Optimize energy to the maximum: Maximize the generation of energy from the solar panels. To do this, the panels are isolated individually in order to increase energy production, and thus improve the overall performance of the installation.

Monitoring and protection: A solar inverter monitors the PV system's energy yields, electrical activity and signals when problems arise.

Constant operation: A PV system is designed to provide power in all weather conditions. The PV inverter provides constant operation by dissipating heat in a consistent manner.


There are different types of inverters

String inverters

Most small-scale solar power systems use a string inverter, also known as a "centralized" inverter. In a solar self-consumption system with a string inverter, each panel is connected in series. When they produce power, it is all sent to a single inverter, which is usually located on the side of the house, in the garage or in the basement. The inverter converts all the green energy your solar panels generate into electricity that you can use in your home or business.


Recommendation. Our recommendation for the use of this inverter is that it be used for homes with unobstructed rooftops, which receive constant radiation throughout the day, and for homeowners looking for photovoltaic systems at the lowest cost.


Microinverters

If a string inverter can be considered a "centralized" inverter, microinverters are "distributed" inverters. In PV systems with microinverters, each solar panel has a small solar inverter installed. Instead of sending power from all the panels to a single inverter, microinverter systems convert DC solar power to AC power on the rooftop itself.


Recommendation. This type of inverter is typically used for solar panels with different orientations, homeowners who want to maximize solar energy production in a small space, and homes that have "complicated" roofs with chimneys or other objects that may cause shading.


Power optimizers

Power optimizers can be considered a middle ground between string inverters and microinverters. Like microinverters, power optimizers are located on the roof next to - or integrated with - the individual solar panels. However, systems with power optimizers still send power to a centralized inverter.


It works differently from the inverter in that it searches for the maximum power point by taking into account the power of the PV array; whereas the optimizer acts on each PV panel, which increases the accuracy in locating the maximum power point.


Recommendation. Owners who are willing to pay more to increase the efficiency of their solar panel system, but do not want to purchase microinverters. With the power optimizers we achieve that certain limitations, such as shading, are reduced.
