Brayam Rosero
CEO
With 8+ years in the solar industry, I envisioned starting a company aimed at improving upon the common downfalls of competing solar companies, all while maintaining the utmost standards of service. I enjoy and believe in the importance of interfacing directly with clients, in order to emphasize our product quality and your satisfaction.

Providing value and undivided attention to customers is the at cornerstone of Ultimate Solar’s values. Understanding solar technology should not be complex or confusing. Our job is to ensure you are well taken care of, and that you have a seamless experience when going solar.

We are brokers with the sole goal of determining and implementing the best solar product for you. We understand how overwhelming it can be to undertake a project of such magnitude, and we believe our experience can serve to smooth that process. Regardless of the scale of the job, whether it be a small 7-panel project or a multi-million dollar commercial project, we make it our priority to find the right fit for you.
