For commercial sites, also prioritise inverter selection, panel efficiency, string design, and electrical compliance, since these factors influence uptime and long-term output.
How to compare providers without getting stuck in sales talk
When comparing suppliers, request like-for-like quotes so you can evaluate value, not just price. Look for warranties that clearly cover panels and inverters, plus workmanship and system performance.

Higher efficiency can reduce roof footprint, while robust mounting and weather-rated components help maintain output in demanding conditions. Consider whether monitoring is included, since granular data can help identify issues early. If your site operates during peak demand hours, ask how the system design aligns with consumption patterns to maximise financial benefit.
