Building Maintenance into the Blueprint

Building Maintenance into the Blueprint: The Key to Sustainable Solar Tenders

Solar power is one of the fastest-growing energy sources worldwide, but in the enthusiasm to deploy solar panels, many projects are failing to consider the long-term reality of maintenance. Too often, tenders focus heavily on installation and theoretical performance guarantees while neglecting the practicalities of keeping a system running efficiently for decades. When maintenance is treated as an afterthought, solar projects suffer from reduced performance, unplanned costs, and even premature failure.

To avoid these pitfalls, maintenance considerations must be embedded in the tendering process from the outset, and there are several considerations involved in getting this right.

The Illusion of Guarantees

When drafting a solar tender, it is easy to be drawn into ambitious SLAs that promise near-flawless system uptime or rapid response times. However, these guarantees often crumble under real-world conditions. A contract that demands immediate response to any failure may not account for the difficulty of reaching remote installations or the realities of supply chain delays for replacement parts.

Instead of rigid, unrealistic commitments, tenders should focus on meaningful performance metrics. Guarantees should be measurable, enforceable, and relevant to system efficiency, rather than broad statements that are difficult to validate. Response times should be structured based on the severity of an issue — while a full system failure may demand urgent action, minor inefficiencies might be addressed on a longer timeframe.

Weather conditions should also be factored into maintenance expectations. A contract that does not account for weather-related delays sets up both the provider and the client for conflict. Similarly, ensuring that key spare parts are readily available rather than dependent on unpredictable supply chains will significantly reduce unexpected downtime.

The Pitfalls of an Overloaded Scope

Many solar tenders suffer from an overly exhaustive maintenance scope. While comprehensive maintenance might sound ideal in theory, the reality is that many checklists are filled with requirements that add cost but little actual value. A well-designed tender will separate necessary maintenance from “nice-to-have” activities, focusing on tasks that directly impact performance and longevity.

For example, while panel cleaning is essential in areas prone to dust or pollution buildup, in other environments it may have minimal impact. Inverter inspections and cable integrity checks are crucial, while excessive data reporting requirements can create administrative overhead without improving system outcomes. Instead of demanding every possible inspection and service, tenders should focus on core preventative measures that truly keep systems running efficiently.

Another common issue is the inclusion of performance guarantees that are difficult to measure or enforce. A commitment to a specific percentage of system uptime may sound reassuring but can be nearly impossible to track without a robust monitoring framework. Performance thresholds should be clearly defined with transparent measurement methodologies so that both the client and the service provider understand expectations.

Designing with Maintenance in Mind

Many maintenance headaches arise from poor system design. When systems are built without consideration for long-term servicing, routine maintenance becomes expensive, time-consuming, and difficult to execute. A tender that includes design specifications aimed at ease of maintenance will save money and effort over the lifetime of the system.

Solar panel layouts should allow for easy cleaning, access and inspection, avoiding overcrowding that makes servicing difficult. Cable management is another critical area — if cables are bundled haphazardly, troubleshooting and repairs become a nightmare. Clearly labelled and neatly arranged wiring significantly reduces repair times. Access to key system components should also be a design priority. If an inverter or junction box is difficult to reach, servicing costs will be unnecessarily high.

Component selection plays a major role in long-term serviceability. Some solar panels and inverters are designed to be easily repaired, while others require full replacements if anything goes wrong. A well-structured tender will specify equipment with long-term serviceability in mind, considering factors like the availability of spare parts and the manufacturer’s commitment to ongoing support.

Modern monitoring systems should also be an essential requirement. Instead of relying on manual inspections ONLY, smart monitoring can provide real-time insights into system performance, allowing for predictive maintenance rather than reactive repairs. Automated alerts for underperformance or potential failures enable swift intervention before a minor issue becomes a major problem.

Ultimately, what this all comes down to is the need for flexibility when structuring a maintenance contract. No two sites will be the same, and therefore a templated approach to maintenance isn’t going to deliver value for anyone involved. Instead, the specific conditions at play need to be factored into the maintenance contract, and it is only by doing that a solar installation can remain efficient and cost-effective for decades.
