Maximize the Value of Your Existing Solar Assets​



What is Repowering?


Repowering involves upgrading or replacing key components of an existing solar system—such as modules, inverters, or electrical infrastructure—to improve performance, reliability, and energy output.

Rather than replacing an entire system, repowering allows asset owners to modernize critical components, address degradation, and align with current technology and compliance standards.

This process allows asset owners to:

  • Improve system efficiency and energy production
  • Reduce ongoing operations and maintenance costs
  • Extend the useful life of the asset
  • Align with current codes, technology, and compliance requirements

Our Approach to Repowering


Legacy Power approaches repowering with a focus on performance, risk management, and long-term asset value.

We begin with a comprehensive evaluation of your system, identifying performance gaps, equipment limitations, and opportunities for improvement. From there, we develop a tailored upgrade strategy aligned with your operational and financial goals.

Our team manages the full process—from engineering and procurement to installation and commissioning—ensuring a seamless transition with minimal disruption to ongoing operations.

What we evaluate to ensure each project delivers measurable value, we assess:

  • System performance and degradation trends
  • Equipment condition and remaining useful life
  • Warranty coverage and transferability
  • Equipment compatibility and bankability
  • Revenue impact and downtime considerations
  • Code compliance and interconnection requirements
  •  

Why Legacy Power


Repowering requires more than construction expertise—it demands a deep understanding of system performance, financial impact, and long-term asset risk.

Legacy Power brings an asset-focused approach to every project, combining technical execution with real-world experience operating and upgrading existing systems.

We evaluate each system holistically—considering performance history, warranty status, and revenue impact—to ensure upgrades are both technically sound and financially effective.

Our team works closely with equipment manufacturers to help preserve or enhance applicable warranties wherever possible. We also support warranty reviews and claim coordination, helping asset owners navigate complex coverage requirements throughout the repowering process.

With experience working on live, operating assets, we execute projects with minimal disruption—protecting uptime, energy production, and revenue generation.

By prioritizing bankable technologies and disciplined execution, Legacy Power delivers repowering solutions designed to improve reliability, reduce lifecycle costs, and maximize long-term asset value.
