Based on what little I've done so far in terms of understanding how to size a system based on average, peak, and total annual use, I have some numbers of what "might" be the right amount of output for my use. I also have some ideas on what sort of panels to consider, size, and how that might end up being installed. But, I have a number of questions...
- While I probably COULD do the install myself, I probably don't want to... mostly because the potential target roof area sits two full stories up and I'd be working alone. Are there recommendations on how to find decent installers in my local area to work with? I may be willing / able to do certain parts of the work although expect that won't be "allowed" as soon as someone has been hired to do it...
- At what point in the conversations do I ask sellers / installers things like what specific brands of panels and inverters they use or what the wattage per panel is (and why they use those particular ones)?
- If I'm looking at a system that's roughly 11-12kW in size, what MIGHT be a total cost for the hardware only if I'm looking at solar only, grid-tied, net metering, and no battery components using high efficiency / higher output panels (450-500W each)?
- What might be the installation costs to put in a system that's two dozen panels?
- How can I ensure that the wiring and components under the panels are protected with screens or similar to keep animals and such out?
- The roof is a 30 year architectural shingle roof that was installed about four years ago. Any tips or suggestions on better time of year to do a solar install to prevent damage to the roof while ensuring everything gets sealed up well?
I am fully expecting a materials cost in the $10k+ range but am not sure how much beyond that it might go. It would be great to learn that I'm over-estimating, but I doubt it. :)
Any particular tips on this would be of interest for me to start down the path as I probably wouldn't end up having everything I need until probably the spring time (after the snow and ice are gone from the roof!)
