Hello, My company has worked on designing and prototyping either standalone solar panel systems, or systems that integrated them. It would be best to get on a call and determine all specs. We would then write up a document on the tech we will need and make sure everything is in place. Our team of former Intel members can help you from investigation to manufacturing. Regards, Zach
