How to Choose the Best Solar Panel Brand and Installation Company

A solar power system offers a guaranteed return on investment, but only if you use high-quality products installed by professionals. Remember that solar panels are electrical devices, and they need adequate wiring and protections like any other system with voltage and current.

Also, consider that solar panels are intended to operate for decades, and they need a reliable racking system that resists high winds and other harsh weather conditions.

Before installing solar panels for a home or business, a very important step is choosing your product brands and installation company. Keep in mind that solar panels are only one part of a functional photovoltaic system, and you need to ensure that all components are safe and durable.

For example, you need a high-quality inverter to convert the output of solar panels into a stable AC voltage supply, and you need a tough racking system to hold the modules in place.

In this guide, we will provide some recommendations when choosing solar panels, inverters, and other system components. We will also discuss what to look for when comparing solar installers, to ensure that all elements of your PV system are properly installed.

The last thing you would want is purchasing a top solar panel brand, only to have your warranty voided by a poor installation procedure.

Residential vs. Commercial Solar Panels: What’s the Difference?

When comparing different brands of solar panels, you will notice that some models are described as “residential”, while others are described as “commercial”. However, this is just a naming convention for different panel sizes, and both types are composed of the same building blocks: solar photovoltaic cells.

A residential solar panel will normally have 60 cells, while a commercial panel has 72 cells. 60-cell solar panels are preferred in home installations since they use roof space more efficiently thanks to their compact design.

On the other hand, 72-cell panels are preferred in commercial and industrial buildings with abundant roof area, where larger panels can be installed with ease. However, commercial panels will work just fine on some homes, and the same applies for residential panels used in commercial or industrial buildings.

As we discussed in a previous article, solar cells can be classified into monocrystalline or polycrystalline, depending on their material structure at the microscopic level.
