When considering solar for your organization, it's logical to want to know about system maintenance. Modern solar panels are very durable with operational lives measured in decades. The good news is that maintenance is fairly minimal if done regularly, but consistency is the key.

We recommend regular cleanings and system check-ups or a more comprehensive maintenance and repair program to ensure that your system always operates at peak efficiency.

Commercial solar energy installations are complicated systems, with tens of thousands of interconnections contributing to overall system performance. A good O&M program will ensure that every aspect of the solar ecosystem is watched and brought back into spec when needed.

Outlining every aspect of a comprehensive O&M program would be far too lengthy to complete in a short blog post. With that said, below are some common questions we receive about commercial O&M to help you understand the importance of maintaining your organization's solar energy system.

What, exactly, is commercial solar O&M?

Solar O&M usually falls into monitoring, preventative maintenance, and repairs.

  • Monitoring: Although solar is typically a low-maintenance technology, it can be beneficial to have monitoring available to ensure that the system's many panels and interconnections are always working together as intended. Most O&M service providers offer remote monitoring packages to help spot performance issues, repairs, or even unexpected system outages as quickly as possible.
  • Preventative maintenance: As with any technology, pre-emptive care and maintenance will ensure your solar energy system's longevity and efficiency. Preventative maintenance is the best way to avoid costly repairs and system outages due to equipment issues. Panel cleaning and annual equipment inspections fall under this category.
  • Reactive Maintenance: Even the best-kept solar energy systems might need repairs from time to time. Troubleshooting, diagnostics, manufacturer warranty repairs, replacements, and upgrades might be needed to keep your solar energy system operating at ideal levels. 

Why is ongoing O&M important?

Going solar is a sizable investment your organization can reap the benefits from for decades. Because of the significant time your solar energy system will work for you, routine maintenance and checkups will improve ROI by ensuring efficiency and expanding the system's operational lifespan. With monitoring, you may know that your system is down or that components are malfunctioning. Why wouldn't you want the security of a qualified O&M team to help you with such a large investment?

How much does commercial solar O&M cost?

The cost of O&M can vary greatly depending on several factors. The proximity to your O&M provider, system size, and type are the biggest factors determining your overall maintenance cost. For example, a large solar carport system 100 miles away from your O&M provider will most likely cost you more for O&M services than a smaller rooftop array 15 miles away. A solar carport is harder to access than a rooftop (it might require scissor lifts or other equipment), and a larger system will generally require more resources. There is more distance to account for when dispatching an O&M team.

What should I look for in a commercial solar O&M provider?

Only some O & M providers are created equally, and the level of service you choose will depend on your budget and needs. At the base level, your O&M provider should cover monitoring, performance alerts, and preventative maintenance, like inspections. You'll also want a competent team who can handle escalations of issues quickly and will respond to you promptly. Time is money when your solar energy system is down, so having a responsive O&M provider is key.

If installing solar in multiple locations, using an O&M company to service your locations can be important. If you're dealing with a specific kind of equipment, hiring an O&M team that is experienced and knows how to work on it properly can also be beneficial. Be sure to cover these items when talking to an O&M team to ensure the best care for your solar investment.
