Beware of Imoh Essien. He knows a lot about solar and conning people. Contracted in October and didn't start the installation till January. Lost out on getting my tax credit on 2018 taxes. He had the panels installed and never came back to finish the job. It was so bad I had to pay to have the panels taken down and installed correctly and finish the job. His insurance was expired and his license didn't have a master electrician and was not to do business. He only came around to collect money and never looked at the installation to see if it was done right. Don't let this happen to you.
