Solar Installers Find Gold in Aging Rooftop Systems

The first wave of rooftop solar panels is getting old, and that's creating an unexpected opportunity for solar installers across America.

Tigo Energy just released a comprehensive playbook helping contractors tap into the growing market of aging solar systems. More than 11 megawatts of solar repowering projects have already been completed using their approach, with some partnerships replacing over 1,000 inverters.

The opportunity is huge. While solar panels themselves last for decades, the supporting equipment wears out much faster. String inverters, shutdown devices, and monitoring hardware typically need replacement within ten years.

Many installation companies have closed over the past decade, leaving millions of homeowners without anyone to call when something breaks. These "orphaned" systems need qualified professionals for maintenance, repairs, and warranty claims.

Homeowners want more from their solar systems today than they did ten years ago. Rising electricity costs and changing utility policies have sparked interest in battery storage and whole-home backup power. Many people want their systems ready to charge electric vehicles too.

The playbook outlines three service tiers contractors can offer. The restore option focuses on repairs and diagnostics. The optimize tier upgrades inverters and adds advanced monitoring. The future-proof package adds battery storage and prepares homes for increased power needs.

Instead of waiting for emergency calls, successful contractors are proactively reaching out to customers. They're using permit databases to find systems installed ten or more years ago and partnering with roofers and electricians who spot aging equipment during home renovations.

Tigo recommends a 90-day rollout plan for contractors entering this market. The first month focuses on training teams and creating service packages. Month two launches targeted marketing and local outreach. By month three, installers close their first projects and build case studies to attract more customers.

The Ripple Effect

This shift from one-time installations to ongoing service relationships benefits everyone involved. Homeowners get reliable support for their aging systems without expensive full replacements. Contractors build predictable, recurring revenue streams that survive market ups and downs.

The repowering approach also extends the life of existing solar installations, maximizing the environmental benefits of systems already in place. As electricity grids strain under growing demand, keeping millions of rooftop systems running at peak efficiency matters more than ever.

Communities gain too. Local contractors who master repowering services create stable jobs and become trusted long-term partners for their neighborhoods. The work stays local instead of depending on large national installers.

Contractors are transforming aging rooftops into modern energy powerhouses that can serve families for decades to come.
