Customers consistently mention responsive communication from the first consultation through installation. Several reviews note clear pricing and solutions tailored to budget, including help identifying financing options. Homeowners also call out reliable scheduling and crews that work efficiently, even in hot weather. A few reviewers specifically praised successful inverter upgrades on older systems.

Phil Seastrand on eFlow Solar Energy

We have a 12-year old system with the original Enphase inverters that was experencing some issues. We took advantage of an inverter upgrade promotion that was offered by Enphase but we needed to find an installer to do the work. This proved to be difficult as it wasn't a new install. We eventually found Michael at eFlow Energy who was willing to give us a quote to perform the work. Rich and team did an excellent job swapping out the inverters and getting the system back up and running. Unfortunately, we had three bad inverters and Rich needed to come out multiple times to diagnose and then replace the bad inverters. Most companies would have said no way, not worth their time, but Rich and eFlow came through for us and made everything right. I really appreciate a company that stands by their work and does the right thing for the customer. Rich, Michael and the eFlow team did an excellent job and will have my business in the future.

Brenda Turner on eFlow Solar Energy

Using eFlow Solar Energy to install our homes solar panels was the best decision we made. The owner, sales crew, as well as their installers, were friendly, knowledgeable and reliable. They were able to find a solution that fit within our budget along with a reasonable loan to fit our need. They worked quickly, even in the blazing summer heat. I've already recommended eFlow to others.

Erik Henry on eFlow Solar Energy

Very pleased with eFlow Solar's consultation and installation processes. Rich, Mike, and the rest of the team are friendly and helpful, and we are confident that they worked diligently to get us the best deal and get our installation done in a safe and timely manner. Everything seems to be working fine so far and we love that they offer a warranty and honor military/veterans. We can even monitor the way our panels are working. Definitely recommend!

William Charlson on eFlow Solar Energy

eFlow installed the solar panels on our vacation rental Lodge right outside of Yosemite. They were honest, polite and helpful through the whole process, from securing financing through the installation.
Chanelle was wonderful to work with and always a call away if we had any questions.
I would recommend eFlow for your solar needs!
