Development of electrical performance testing standards for the acceptance of solar photovoltaic projects based on field experience and observation

As-built performance requirements are becoming more common in Interconnection Applications (IAs) and Power Purchase Agreements (PPAs). Often overlooked as, “just the last step in the commissioning process,” it is important to understand the scope of the testing requirements before committing to the agreement. The worst case scenario is when your project has design flaws that prevent it from meeting requirements. By the time the system is discovered to be failing, it can be too late and too costly to fix. Understanding standards for performance testing can help guide project design to ensure better success meeting those requirements later on.
