Frequently Asked Questions About Commercial Solar Installations

What is a net metering agreement, and why is it important?

A net metering agreement is a contract between a utility company and a solar system owner that allows the owner to sell excess solar energy generated by their system back to the grid for credits on their electricity bill. It's an important policy that encourages solar adoption by providing a financial incentive for solar energy production. With net metering, your electric meter runs backward when your solar panels generate more electricity than you consume. The credits you accumulate from this excess energy can offset your electricity bill during periods when your solar panels are producing less energy, such as at night or during cloudy days.

Can I add battery storage to my commercial solar system later?

Yes, you can typically add battery storage to your commercial solar system at a later time, even if you don't initially include it in your installation. However, it's generally more cost-effective to integrate battery storage during the initial installation, as it allows for a more streamlined design and installation process. If you're considering battery storage in the future, discuss this with your solar installer during the initial consultation and system design phase. They can design your system to accommodate future battery integration, making the addition of batteries smoother and potentially less expensive.

What is the lifespan of a commercial solar system?

Commercial solar systems are designed for longevity and typically have a lifespan of 25-30 years or more. The panels themselves will continue to generate electricity beyond that timeframe, but their efficiency may gradually decline. Inverters typically have a shorter lifespan of 10-15 years and may need to be replaced during the system's lifetime. Reputable solar panel manufacturers offer warranties that cover defects in materials and workmanship for a significant portion of the system's lifespan.

Can I install solar panels on a flat commercial roof?

Yes, solar panels can be installed on flat commercial roofs. In fact, flat roofs often provide an ideal surface for solar installations, as they offer:

• Ample Space: Flat roofs typically have more usable space than sloped roofs, allowing for larger solar arrays and greater energy production.
• Ease of Access: Flat roofs are generally easier to access for installation and maintenance.
• Flexibility in Orientation: Solar panels on flat roofs can be tilted and oriented in any direction to optimize sun exposure.

Specialized mounting systems are used for flat roof solar installations to ensure proper tilt angles for optimal energy production and secure attachment to the roof surface. Your Commercial Solar Installers will determine the best mounting system and layout for your specific flat roof.
