What Our Clients Say
I 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!!
Linda Martin
Client of Otter Energy
Just 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.
David Dudley
Client of Otter Energy
Long process but Otter made it clear and simple and guided me throughout the process from sales, installation and after sales and also helped me to get all the government credits. Otter is and will continue to be my go company for any Solar/Battery solutions.
