Frequently Asked Questions About Commercial Solar Installations

How do I calculate the ROI of my commercial solar investment?

Calculating the ROI (return on investment) of your commercial solar system involves considering various factors:

• System Cost: The total upfront cost of the system, including panels, inverters, installation, permitting, and other expenses.
• Energy Savings: The estimated annual savings on your electricity bill based on the projected energy production of the system.
• Incentives and Rebates: Include any applicable tax credits, rebates, or other financial incentives that reduce the net cost of the system.
• Depreciation: Factor in the depreciation value of the system over time, which can reduce your tax liability.
• Maintenance Costs: Estimate the annual maintenance costs for your solar system.
• Electricity Rate Inflation: Consider the potential increase in electricity rates over time, which will amplify your energy savings from solar.

A qualified solar installer or a financial professional can help you calculate a more precise ROI for your specific project, considering all relevant variables and financial projections.

How do solar panels affect my building's insurance?

Installing solar panels on your commercial building may require you to update your insurance policy. It's important to notify your insurance company about the solar installation, as it adds value to your property and may require specific coverage. In many cases, your existing insurance policy may already cover solar panels as part of your building coverage. However, you may need to increase your coverage limits to reflect the added value of the system. Some insurance companies offer specialized solar panel insurance policies that provide comprehensive coverage for the system itself, including protection against damage, theft, and loss of production.

Are there different types of net metering policies?

Yes, there are different types of net metering policies implemented by utilities, including:

• Full Retail Net Metering: The most favorable policy, where you receive full retail credit for excess solar energy sent to the grid. This means you get the same price for the electricity you sell back as you pay for the electricity you buy from the utility.
• Time-of-Use (TOU) Net Metering: The value of the credits you earn varies depending on the time of day you export electricity to the grid. Higher credits are typically offered during peak demand periods.
• Net Billing: You receive a lower rate for excess solar energy than the retail rate you pay for electricity.
• Feed-in Tariffs (FITs): A separate meter is used to measure the solar energy you export to the grid, and you are paid a fixed rate per kilowatt-hour for this energy, which may be different from the retail electricity rate.

The specific net metering policies vary by state and utility company, so it's essential to understand the regulations in your area.

Do commercial solar panels require regular cleaning?

While regular cleaning is not always mandatory, it's generally recommended to clean commercial solar panels periodically to ensure optimal performance. Dirt, dust, pollen, bird droppings, and other debris can accumulate on the panels, reducing their efficiency and energy output. The frequency of cleaning depends on factors such as:

• Location: Areas with high dust, pollution, or bird activity may require more frequent cleaning.
• Panel Angle: Flat or low-sloped panels tend to accumulate more dirt than steeper panels.
• Rainfall: Areas with regular rainfall may need less cleaning, as rain can help wash away some debris.

A simple visual inspection can help you determine if your panels need cleaning. If you notice a significant amount of dirt or debris, it's a good idea to have them cleaned. You can hire a professional solar panel cleaning company or consult with your installer for recommended cleaning methods and frequency.
