As usual, the Forums don't show me new posts on topics I create until I post a reply, so missed all this. Lots of interesting points, unfortunately sprinkled with a fair amount of animosity. However, even people I don't always agree with had some interesting points. Wayne for example made me think that the solar Return On Investment (ROI) really should factor in the costs of replacing the system at some point. Aside from the labor involved, how do I dispose of the old panels?
I suppose when replacing the system, that becomes part of that ROI. My age will factor in whether that ROI impacts me or the next person that buys my house. It will also impact me if I buy a house with solar already, but costs are coming down to the point that the ROI for a new system is less years than the warranty period of the inverter, but part of that is also because of how much electricity has gone up.
The electricity costs are part of that "pressure" to move in the direction of solar. I am not forced to do this, but when it starts costing me more NOT to go to solar, it makes less sense to resist going this way. My global influence is less than miniscule, but my ability to control MY costs is not.
As for system costs, if I look at the best prices I can find for a 10KW system, I am right around $10K (without batteries or labor). My last couple of electric bills were just over $300, so ROI isn't too far off when it's costing me nearly $4K/year for electricity. The system would be paid off before any of the warranties expired.
The other problem is that this was based on the best panel prices I could find. Unfortunately I cannot get those panels for that cost in the US unless I want to take a chance on ordering from Alibaba. com .
