For most people exploring solar and battery storage for their company, this operational question often looms large: once this system is built, what does my team have to do? The fear is that owning an energy asset means inheriting an ongoing technical burden. The reality is more straightforward, and understanding it changes how businesses evaluate the decision.
Once the System Is Built, Maintenance Is Mostly Contracted Out
When designed and installed correctly, an onsite solar or battery storage system, requires very little day-to-day attention from the owner. The technologies are mature. Solar panels are low-maintenance by design. Battery storage systems operate reliably and come with manufacturer service agreements that cover most failure scenarios.
Whether a business finances the system through a power purchase agreement or owns it outright on its balance sheet, the ongoing maintenance model is similar. In a PPA, the developer or third-party owner manages everything. In a capex ownership scenario, the standard practice is an operations and maintenance contract, typically offered by the engineering, procurement, and construction firm that built the system. That contract covers 24/7 remote monitoring, annual site inspections, and on-call repair crews for any equipment failures. The internal team’s job is to coordinate access and manage that contractual relationship. That is largely the full scope of it.
The analogy that holds up well here is HVAC. A company’s facilities team does not need to become HVAC engineers to benefit from climate control. They hire a service firm. Onsite energy works the same way.
What O&M Contracts Actually Cost
One reason companies overestimate ongoing burden is that they also overestimate ongoing cost. Operations and maintenance contracts for commercial solar and storage systems typically run between $6 and $16 per kilowatt per year, depending on system size and the number of systems under a single contract. For a mid-sized commercial system, that translates to a few thousand dollars annually. Against the electricity cost savings the system generates, that is a nominal expense.
Panel cleaning is a related concern that often comes up and is worth addressing directly. In regions with regular rainfall, cleaning is rarely necessary. In high-dust, low-rain environments, it may make sense, but only when the cost of cleaning is justified by the incremental output it recovers. If it costs $10,000 to clean a system and the improved output over the next period is worth $4,000, the math does not support it. This is a calculation the O&M provider can run and discuss with you.
The Front End Is Where the Real Work Is
The part of the process that does require genuine organizational effort is the development phase: deciding whether to build, where to build, what kind of system to deploy, how to finance it, and who should build it. This is typically a three-to-six-month process, and companies can approach it with varying levels of hands-on involvement. Some organizations want their team to know every detail. Others make a handful of key decisions at defined milestones and delegate the analytical work.
What matters most at this stage is internal alignment. The decisions about financing structure, system design, and supplier selection touch operations, finance, sustainability, real estate, and executive leadership. If the right people are not enrolled at the start, the project tends to generate rework. A sustainability lead discovers the system was specified without factoring in resilience requirements. A CFO raises a concern about balance sheet treatment that sends vendor proposals back for revision. Getting stakeholder input before going to market avoids these scenarios and often saves months of back-and-forth.
The Hidden Cost of Working Without a Process
Many organizations underestimate how much unstructured solar procurement costs in time and organizational energy, even when nothing goes wrong. Companies fielding inbound pitches from vendors without a consistent evaluation framework spend significant hours comparing proposals that were not built to the same specifications. Business cases get rebuilt multiple times for different internal audiences. Projects stall not because the economics are bad but because the internal process never created a clear path to a decision.
A structured approach, with defined criteria, clear roles, and a repeatable workflow, reduces total time commitment and makes it possible to move more projects from evaluation to construction. Companies that have tried to build this process from scratch and then adopted a purpose-built platform consistently report that the work they did before finding a better approach was their most expensive phase.
What to Consider from Here
If your organization is weighing the decision to invest in onsite energy, the most productive starting point is getting clarity on your objectives before evaluating any system designs or vendor proposals. What problem are you trying to solve? Cost reduction, grid resilience, emissions targets, or some combination? Who in the organization needs to be part of the decision? How does the company prefer to finance capital projects?
VECKTA works with businesses to build that foundation before going to market, so that when supplier proposals come in, the evaluation is rigorous and the decision-making path is clear. The goal is a process where the organization is in control of the outcome, not responding to whoever showed up with the most compelling pitch.
