Our Testimonials
What People Say?
Otter Energy's personnel at the sales end, in the front office and during the installation stages were excellent in communication, organizing and problem-solving. Our house is considerably outside the normal range for Otter to work in so their efforts to make everything work using a third party team at times resulted in some minor delays. The electrical work was always neat --to the point of being aesthetically pleasing when a faster, shorter route was possible. The installers were efficient, polite and solicitous of our possible concerns and Mike, Meg and Ron answered our queries quickly and fully. They were as helpful as my original background investigation suggested. The system is up and running smoothly, thanks to the employees engagement and the firm's culture of customer support.

Client of Otter EnergyI took the Federal interest free funding to put solar on my roof this past winter. Otter Energy was excellent in helping me with the forms and completing the work in time for the spring sun. My first solar month was March. We had terrible weather with 2 ice storms, heavy rain and the usual overcast as I live in PEC with influence from Lake Ontario. My Hydro One bill was a shock. I had generated $400.00 worth of power!! You may not know that Rural delivery is almost as much as the electrical usage. As advertised, Otter was right. If you drop your kwh your delivery also decreases. Pick Otter for your solar project. This is amazing!!

Client of Otter EnergyJust celebrated the 12 months in service for my 18 panel solar system.The solar systems annual production was 9.0Mwatts which is what the Otter Energy quoted and installed.This combined with Heat Pumps replacing my gas furnace and water heater and Elexicon Net metering now gives me a net zero home. My only cost is the utility connection charge Thanks
