1. Switch to traditional forms of energy.
2. You have a lot more hot water. Longer showers, cleaner dishes, etc. :)
3. It can be expensive. Best to do an ROI analysis. It may never pay for itself.
“1. Switch to traditional forms of energy.”
That simply doesn’t apply to this threads main point, PASSIVE solar. No extra cost, just sensible house and window orientation.

Again these apply to ACTIVE PV and solar hot water systems. Not passive solar. Yet both of these systems will normally pay for themselves. What a strict ROI does not tell you is all the other benefits like still having electricity and hot water when that ice or wind storm comes that takes out all your neighbors power. How do you put a price on that or self-sufficiency?
