“Bay4 has provided RC Energy Group LLC excellent independent engineering support. The staff is highly knowledgeable about technical and operational matters for a full range of solar PV facility issues. Bay4 has improved the quality of the projects we developed by providing a thorough technical review of the underlying design prior to the start of construction and identifying potential concerns before they become problems. Whether that be issues related to the underlying production estimates or possible inconsistencies in the design drawings, Bay4’s efforts help to get the project off to a good start. Once construction is underway, Bay4’s onsite visits are valuable in the opportunity they provide to ensure the work adheres to the manufacturer specifications, thereby protecting future warranty rights. Furthermore, the experience Bay4 has operating systems allows its staff to recommend best practices that will help to maintain the system in good working condition for years to come. We are quite pleased with Bay4’s work. The staff is thorough, thoughtful, and adds value to our systems. We are pleased to have them as our partner.”
