Solar panels are one of the best alternative energy ways to save money while also helping the environment and reducing their owner's reliance on non-renewable resources. However, solar energy systems are only as good as their quality. High-quality solar panels will produce more electricity than lower quality ones, because of higher efficiency and capacity.

This article will explain what makes a solar panel commercial-grade, why it is important for your business, and how you can tell the difference between different qualities of commercial solar panels.

What is a commercial-grade solar panel?

A commercial-grade solar panel is a type of solar panel that is specially designed to be durable and efficient under heavy use. These panels are typically used in large-scale or commercial applications, such as on rooftops at businesses and factories, or utility-scale installations like solar farms. Compared to residential solar panels, commercial solar power systems typically have higher efficiency ratings and a longer lifespan.

Any additional power generated is sold back to the grid, creating a financial surplus for the companies commercial solar systems that generate additional energy. This system helps feed energy back and forth between the grid and the end user i.e. companies with solar systems installed.

Certain companies may need to store additional power for later use, this is typically done by storing solar energy in commercial sized batteries. These batteries can then be used to store or transport the generated energy to its necessary location.

Types of a Commercial Solar System

There are two main types of commercial-grade solar panels: monocrystalline and polycrystalline.

• Monocrystalline Panels

This type of commercial-grade solar panel is made from a single, large crystal of silicon. Monocrystalline panels are typically more efficient than polycrystalline panels and can last for decades under heavy use and harsh weather conditions.

• Polycrystalline Panels

This type of commercial-grade solar panel is made from multiple small crystals of silicon that are fused together to form a single layer. While polycrystalline panels do not have the same level of efficiency as monocrystalline panels, they tend to be cheaper, making them a good choice for large-scale applications where cost is a major consideration.

Importance of Choosing a High-Quality Commercial-Grade Solar Panel

There are a few key reasons why it is important to choose a high-quality commercial-grade solar panel for your home or business:
