Who maintains your commercial rooftop solar system? Understanding operations and site access

Introduction

One of the most common questions we hear from asset management teams considering rooftop solar leases is: "What happens after the panels are installed?" It's a smart question—especially when you're managing a portfolio of properties and need clarity on long-term responsibilities, ongoing site access, and what to expect from your solar developer partner.

The good news? When you lease your rooftop to a solar developer through a rooftop leasing agreement, the developer takes on virtually all operational responsibilities. Your role is minimal, and the ongoing requirements are clearly defined upfront. Here's what you need to know.

Who owns and operates the solar system?

The developer owns and operates everything

In a typical rooftop lease agreement (also called a roof lease or community solar lease), the solar developer owns the solar system and is fully responsible for its operation and maintenance. You, as the building owner, are leasing the roof space—not managing the solar infrastructure.

This means:

• The developer handles all operations: System monitoring, performance optimization, and energy production management
• The developer manages all maintenance: Routine inspections, panel cleaning (if needed), inverter servicing, and component repairs or replacements
• The developer ensures compliance: Permitting, utility interconnection, and ongoing regulatory requirements
• The developer carries insurance: Coverage for the solar system itself, liability, and any damage related to the installation

Your responsibility is straightforward: provide access to the leased roof space and collect your lease payments.

What ongoing site access is required?

Routine maintenance access

Solar developers need periodic access to your rooftop to maintain system performance and meet their contractual obligations. Typical access requirements include:

Scheduled Maintenance Visits

• Frequency: Generally 1-4 times per year for routine inspections
• Duration: Usually a few hours per visit
• Notice: Developers typically provide advance notice (often 24-72 hours) before accessing the site
• Timing: Visits are usually scheduled during business hours and coordinated with your property management team

Component Servicing and Monitoring

• Inverter maintenance: Inverters (the equipment that converts solar DC power to AC power) may require periodic servicing or replacement over the life of the system
• Remote monitoring: Most modern solar systems include remote monitoring, which reduces the need for on-site visits. Developers can track performance in real-time and only visit when physical intervention is needed

Emergency and repair access

In addition to routine maintenance, developers may need access for unplanned repairs:

• Equipment failures: Inverter malfunctions, wiring issues, or panel damage from severe weather
• Safety issues: Immediate access if there's a safety concern or emergency shutdown
• Utility coordination: Occasional access may be needed to coordinate with utility companies for interconnection or grid-related work

These situations are relatively rare with quality installations, but your lease agreement will specify the developer's rights and notification procedures for urgent access.

How site access is managed in practice

Clear protocols defined in your lease agreement

Your rooftop lease agreement will spell out:

• Access rights and limitations: When, how, and under what conditions the developer can access the roof
• Notification requirements: How much advance notice you'll receive for routine and emergency visits
• Coordination procedures: Who the developer contacts (property manager, facilities team, etc.) and how access is granted
• Safety and security protocols: Badging, escorts, sign-in procedures, and compliance with your building's security requirements

Minimal disruption to your operations

Solar operations and maintenance are non-intrusive. Developers access only the rooftop—not tenant spaces or building interiors (except to reach roof access points). Most maintenance is:

• Quiet: Solar panels have no moving parts; maintenance involves visual inspections, electrical testing, and occasional component replacement
• Quick: Routine visits typically last a few hours
• Scheduled: Developers work with your team to minimize any impact on building operations

For multi-tenant properties, tenants are rarely aware of maintenance activity. For owner-occupied buildings, any access is coordinated in advance and planned around your operations.

What about roof work or building modifications?

Your right to access your own roof

Even though you've leased the roof space, you retain the right to access your roof for necessary building maintenance, repairs, or improvements. Your lease agreement will define:

• Your access rights: When and how you can access the roof for your own needs (re-roofing, HVAC work, structural repairs, etc.)
• Coordination with the developer: Procedures for notifying the developer if your work might affect the solar system
• Temporary shutdowns: If your roof work requires the system to be temporarily de-energized or panels to be moved, the lease will outline how that's handled and whether there are any associated costs or "lost energy revenue" provisions

In practice, developers are experienced at coordinating around building owners' needs. If you're planning a roof replacement or major building upgrade, your Lumen Advisor can help facilitate those conversations early to ensure smooth coordination.
