Solar Field Acceptance Test

Solar Field Acceptance Test from HelioPower

As an EPC integrator and owner/operator of more than 120 solar PV systems, HelioPower has performed over 4,000 solar field acceptance tests. Our Solar Field Acceptance and Commissioning Test is a critical, post-construction phase in any solar installation, and ensures that the final product conforms to the owner’s project objectives and requirements. The solar field acceptance test and commissioning milestone is usually the hand-off from the EPC company or EPC phase to the solar maintenance or solar O&M provider.

Solar Field Acceptance Test Phases

Solar Field Acceptance Test Plan

The first step is the development of a solar field acceptance test plan. The plan identifies all the steps required to accept the project as-built and establish a contractual and performance baseline for the new owner.

Solar Asset Acceptance

The asset acceptance phase of the solar field acceptance test matches the system as-designed, with the system as-built.  It includes confirming that all equipment, conductors, and site conditions match the approved engineering documentation and performing a detailed system commissioning procedure.

Solar Asset Commissioning

For solar commissioning and the solar field acceptance test to be most effective, the party performing the solar field acceptance test should have no incentive towards a positive outcome. Contractors or integrators responsible for installing a system will typically be biased towards success since the final payment is likely still outstanding. Particularly for revenue systems, it is important to have a third party conduct the solar field acceptance test.

What We Provide

HelioPower performs solar field acceptance tests on all systems we build.  Our independent asset acceptance service applies to systems we do not build.  When performing solar field acceptance tests for third parties, we review the solar field acceptance test plan, conduct the test, and provide all documentation of as-built conditions, instantaneous power output (IPO) and efficiency. This unbiased observation gives system owners the confidence that their contractor has completed their system completely and correctly, and sets the baseline for monitoring minimum guaranteed generation (MGG).. In many cases, formal, 3rd party asset acceptance is a requirement of financing sources before final payments are released. Even if your system has already achieved Permission to Operate (PTO) and your contractor has moved on, HelioPower can offer peace of mind by confirming your new solar asset is producing as planned and designed, and is actually installed correctly.
