Poor Solar Project Quality Increases Lifetime Costs by Over 20%, Reports HelioVolta
HelioVolta's new report reveals that poorly executed solar projects can increase lifetime energy costs by more than 20%. The analysis covers nearly 8 GW of solar assets.
HelioVolta, an independent provider of field inspection services, has released its 2026 SolarGrade PV Health Report. The report, which analyzes data from nearly 8 gigawatts (GW) of solar assets, found a significant correlation between project quality and the overall lifetime cost of solar energy. According to the findings, projects with poor quality execution can lead to cost increases exceeding 20% compared to those built to high standards.
The report highlights specific issues stemming from low quality, such as installation errors, substandard components, and inadequate performance monitoring. These deficiencies not only reduce energy output but also result in higher maintenance and repair expenses throughout the project's lifespan. HelioVolta emphasizes the critical role of quality control and independent inspections in ensuring the financial viability of solar energy investments.
Alongside the report, HelioVolta has introduced the HelioVolta Quality Standard Awards to recognize companies demonstrating excellence in quality within the solar sector. This year, Onyx Renewables and Greenskies Clean Energy were honored with these awards for their commitment to maintaining high-quality standards in their solar projects.
The findings aim to provide the industry with valuable insights into quality-related risks and best practices. HelioVolta suggests that prioritizing high-quality components and professional installation is essential for maximizing the benefits of solar energy and minimizing unforeseen expenses over the long term.
