Frequently Asked Questions

Commercial solar panels are designed to meet the higher energy demands of businesses, institutions, and industries, typically ranging in capacity from 325W to 400W, which is significantly higher than residential panels. They are known for their efficiency, durability, and high energy production yield, with brands like SunPower, LG, and Panasonic often leading the market due to their quality and warranty terms

When selecting commercial solar panels, consider efficiency, durability, warranty, and the manufacturer’s reputation. The efficiency of the panels is crucial as it determines how much power can be produced per square foot, which is especially important for businesses where space might be limited

The cost of commercial solar installations can vary greatly depending on the size of the system and other factors, but a rough estimate could range from $2 to $3 per watt before incentives. With the right system, businesses can begin to see savings almost immediately, with a full return on investment typically realized within 5 to 7 years due to lower energy bills and tax incentives.

Several incentives can help reduce the costs of commercial solar panel installations, such as the Federal Solar Tax Credit, which allows businesses to deduct 30% of the cost of installing a solar energy system from their federal taxes. Additional state, local, and utility incentives might also be available, further reducing the initial investment

By investing in commercial solar panels, businesses not only reduce their carbon footprint and dependence on fossil fuels but also contribute to local economic growth by creating demand for green jobs. This aligns with the increasing consumer demand for environmentally responsible business practices​
