Great!

We used this company back in 2017 and they were wonderful to work with. We're currently battling an issue with a different company that we found cheaper for a different house using Energy Sage, but I wish we had just used Renewable Energy Design Group instead of gambling on a different company this time! Melvin was particularly wonderful to work with and we're grateful for good solar companies doing good work.

Great Right From Start to Finish

These folks are a pleasure to work with. I found them to be honest, ethical, professional and knowledgeable. They designed and installed a quality system for us that is functioning nicely. We knew what to expect all along as the project progressed. Each member of the team communicated well and responded to our requests. They respected our property and left everything in great shape when the job was complete.

Excellent service

Bought an installed solar grid tie PV system from RED Group. They were completely reliable and did exactly what they promised. Price was in line with other companies. The installation looks very sharp and system is working as intended. They were all very good to deal with throughout the process. Would definitely hire them again.

The system we wanted delivered just as promised!

I am very happy with the installation to this point. Renewable Energy Design Group did everything they promised on time and on budget. The physical installation was of a very professional quality, the clean-up was perfect, the disruption was minimal. Communications were clear, responsive, and all my concerns were answered completely. The utility company appears to be the final roadblock. The code inspector was impressed with the installation with no issues and not we are waiting on final sign-off and start-up when the solar utility meter is installed. We couldn't be happier. The value for the system was best offered by companies we compared.

Good support, and they stand by their installation

My installation was in 2017, and by mid 2025, the unit began to go offline after a few days of operation. Melvin sent his team, and they discovered a faulty circuit breaker, which supplied energy to their subsystems. The were fully accountable, and replaced the breaker at no charge. They also updated my portal registration to allow for data from the portal to be integrated into a home automation system.
