We trust Rick with our PV array design, electrical, structural and civil engineering, utility interconnection, and even custom racking systems. His firm is friendly and professional. Aside from enjoying the excellent customer service, working with one engineering firm, saves us time and expenses.”
~ Brian Miller, President | Professional Electric
“Hands down, Castillo is the best in the industry. Their expertise, value, and quick turnaround are why we install more systems than the competition… You won’t receive a better set of plans from anywhere else. Our crews love Castillo’s designs because of how easy they are to read, for example, they only provide THREE LINE diagrams, which is perfect for my crew members new to solar. If you’re not using Castillo for solar engineering, you’re not growing your business.”
~ Vinnie Anselmo, President | Sunlight Solar

Thank you Castillo Engineering for all of the hard work!”
