The Solar Plus team outperformed! Smart, talented and hard working, they put together a system that far exceeded my expectations. The installation was done on time and right on budget. After a couple weeks of energy generation, Doug added a modification to take full advantage of the 24 panels by adding one of my remote workshops to the system. A neat, clean installation with simple and easy to understand instruction, I am very impressed and highly recommend Solar Plus.

The Best! From installation to accommodating an addition, Doug and his team have provided excellent service. The system is working so well that our bills are about one quarter of what they were prior. I would highly recommend Solar Plus.

I had Doug replace the aged Outback system on the property that we just purchased, with a new modern Outback system. After discussing how to migrate from the old system to new system, without losing power (we are totally off-grid), we signed the contract. Doug began the next week, installing the new Outback components, batteries, and 3 of the new panels (on the lawn) to get us by. We were only without power for a few minutes. Later he removed the old panels, installed the new panels on the roof along with the ones on the lawn. He also switched the house to 240v capable and installed a CAT-5 cable

We had a problem where we did not have more than a showers' worth of hot water. Solar Plus came in, said our 40 gallon water heater was too small, and suggested upgrading to an 80 gallon water heater. We let them upgrade, it, but then we were left with exactly the same problem as before, still only one shower's worth of hot water. So $1600 later and we had no fix. They have refused to come and follow upon this. So avoid this place at all cost.
