It has been explained to us that there are no annual maintenance costs associated with our project. Essentially there is “nothing to do” other than maybe the clearing of leaves that might accumulate around the panels. The only maintenance is the periodic replacement of the inverters as they won’t last the life of the panels which is 20 years. The estimated cost for replacing the invertors is $2500.
We also confirmed that having to replace a panel later on will not affect our contract with the province and that the supply of replacement panels will not be difficult.
The other related issue is the roof itself. One of the reasons that we want to pursue this project now is that the roof is new.
