Photovoltaic Commissioning

As businesses continue implementing photovoltaic (PV) technology, the safety, quality, and reliability of these systems are increasingly important. One way to improve the likelihood of successful PV projects is to incorporate the services of an independent commissioning agent whose primary focus is to protect the interests of the system owner.

Hood Patterson & Dewar (HP&D) works seamlessly with contractors, installers, and manufacturers to bring an informed “third-party” perspective to commissioning projects. Our engineers understand the importance of ensuring your project will be safe and reliable.
