People are frequently concerned about high electricity costs in commercial sectors. By installing a commercial rooftop on grid power plant, companies can either significantly reduce or eliminate their electricity bill up to 100% for 25 years or even more. These solar power plants are recommended for business, commercial complexes, school-college, institutes and industry with high energy consumption.

#1. Types of Commercial Solar System

There are three types of commercial solar systems available on the market today. All of these types are described in detail further down.

On-Grid Solar System – Saving + Grid Export

Off-Grid Solar System – Saving + Backup

Hybrid Solar System – On-grid + Off-grid

How Does a Commercial Solar System Work?

In a commercial solar system, solar panels absorb sunlight during the day and generate DC (direct current) electricity. This electricity then passes through a solar inverter which converts it into AC (alternative current) electricity. This AC electricity is the standard current that is used in our property/company/factory to power the connected load. 

In case, the commercial solar system produces more power than is being consumed, the surplus electricity will automatically be exported to the utility grid via net-metering. The government will adjust the same in your upcoming electricity bill or pay you for the same. 

Hence, a commercial solar system is ideal for all business owners who want to reduce their operating cost by reducing their electricity expenses.
