Our Areas of Expertise
HelioVolta’s renewable engineers have expert knowledge to support a range of clean energy projects and portfolios.



Construction Phase Services
Partner with HelioVolta to identify, resolve, and prevent issues during construction. Our services establish and enforce quality standards from day one, reducing the risk of failure and underperformance during operations.

Milestone Inspections
We conduct inspections at key milestones to verify completion and generate punch lists when necessary. Inspections cover:
- Golden Row
- Mechanical Completion
- Final Completion
- Commissioning
- Post-Commissioning

Construction QA/QC
Our continuous construction QA/QC process ensures projects are:
- Built as specified in engineering drawings
- In compliance with all code requirements and manufacturer specifications
- Constructed with best practices that mitigate safety, reliability, and performance risks

Commissioning & Acceptance
We perform and/or evaluate systems during and after commissioning to confirm reliable operation and performance. Tests include:
- Capacity testing ASTM 2848
- Commissioning testing results overview: String Voc, Imp, Insulation resistance test, IV tracing results
- Electrical testing of inverters and strings
- Data acquisition system validation and troubleshooting
Owner’s Engineering Services
We serve as independent, unbiased partners, ensuring projects stay on track and meet the highest standards throughout design and construction.
Design and Model Reviews
We conduct expert assessments of project plans, components, performance models, and timelines. Our reviews identify risks, ensure compliance with codes and regulations, and validate that projects align with safety, quality, and financial targets.

Construction Oversight
Our field engineers provide hands-on monitoring, ensuring proper equipment installation and addressing issues in real time to prevent costly site-wide errors.

Construction Progress Tracking
We track construction milestones as on-site project managers, using SolarGrade software to keep clients and contractors aligned with real-time digital reporting.

Contractor Management
We evaluate contractor performance down to the subcomponent level, swiftly identifying QA/QC issues for transparent, efficient resolution.

Operations Phase Services
We provide on-call support for asset audits, troubleshooting, failure diagnosis, and risk prevention in operational fleets.

Third-Party Health Assessments
We audit operating assets using advanced visual, thermal, electrical, and lab testing to detect safety and quality risks early. Our statistically significant sampling maximizes insights while minimizing risks and disruptions to ongoing operations.

End of EPC Warranty Inspections
Before EPC warranties expire, we assess project quality to ensure all workmanship issues are identified and addressed. All issues and observations are itemized in geo-referenced punch lists to expedite resolution and simplify the verification of remediation work.

Failure & Underperformance Root Cause Analysis
We uncover the root causes of system failures, fires, and underperformance using advanced testing such as field EL imaging and XCT tomography. Our analysis reveals underlying quality issues that may affect safety throughout their portfolio. HelioVolta’s reports can be leveraged in negotiations with EPCs, O&M providers, and OEMs.

Remediation Oversight
We monitor and verify remediation work to ensure that corrective actions are performed properly. The services help prevent the recurrence of common issues, particularly for components like connectors, RSDs, wiring, and inverters.
Technical Advisory Services
As a technical advisor, we help clients set and achieve quality KPIs across their portfolios.

Standards and Program Development
We help teams establish quality standards for construction, operations, and maintenance while guiding technical decisions at every project stage.
Technical Due Diligence for Acquisitions
We assess assets prior to acquisition through field inspections and desktop reviews, identifying risks at both project and portfolio levels.
Repowering Consulting
We evaluate aging assets for repowering, providing performance analyses, cost-benefit assessments, compliance guidance, and end-of-life management strategies. Our process includes field inspections, testing, and desktop reviews.
Training and Workshops
We deliver hands-on training tailored to your field crews, construction foreman, and asset managers, using real-world insights from our field inspections to address key areas for improvement.
Our Core Capabilities
Visual Inspection (Aerial and Onsite)
We apply rigorous checklists and protocols to quickly identify non-conformities, providing thorough site walks backed by years of field experience.
Thermography (Aerial and Onsite)
Our advanced thermal imaging detects module hotspots, connector failures, wire termination issues, and other thermal anomalies that pose safety, performance, reliability, and fire risks.
Field Electroluminescence (EL) Imaging
We uncover PV module defects invisible to the naked eye with field EL Testing validates manufacturer and EPC warranty claims for shipping damage, improper installation, and force majeure events such as hail and high winds.
XCT Tomography for Connectors
Our XCT scans provide a detailed view into connector interiors, revealing workmanship and product defects that may cause safety, reliability, and performance issues.
Electrical Testing
We conduct comprehensive electrical testing, including IV curve tracing, insulation resistance, continuity, polarity, ground resistance, inverter performance, string-level monitoring, and power quality analysis.
Independent Oversight
We deliver unbiased evaluations of vendor workmanship and equipment performance, offering benchmarking analyses for informed decision-making.
Desktop Reviews
Our experts analyze design plans, performance data, safety metrics, and construction timelines to align projects with larger performance and reliability goals.
Standards Definition
We apply field data and technical expertise to help clients establish contractual requirements and standardized protocols for EPC and O&M activities and to define approved vendor lists (AVLs).
