Tangentially related, there are a bunch of calculators out there for ROI on installing solar, but there doesn't seem to be one that will take into account the opportunity cost of installing solar now instead of waiting until it's cheaper. I would love to see one for that.
- DoingSomeThings 4y agoI've been thinking about this a lot with the current congressional action. I need a new roof ~now. But I have a lingering fear that huge product improvement will happen in the next 18 months due to added government money. I don't know enough about the industry to weight in that possibility.
- pydry 4y agoI'd absolutely do it now. The price of solar has been beneath that of racks, mounts, wiring and installation for a while now. Even assuming a major breakthrough your costs probably wont change that much because panel cost isnt a big % of what your costs will be anyway. There's also a risk that supply chain bottlenecks/cold war with china will drive up the cost & your electric bill is only gonna go up.
- Daneel_ 4y agoAgreed, do it now. The cost of panels in Australia is already going up due to supply issues thanks to covid, and I don't think you'll see prices come down again for a few years even with that investment.
- reylas 4y agoKeep in mind, with the new law you are talking about, more money will be dumped into the market with no increase in supply. That is what is called inflation. If people have an extra 7500 to buy solar, then solar becomes up to 7500 more expensive.
- gregable 4y agoThis assumes supply is perfectly inelastic. Even assuming, it also ignores the fact that the money is only dumped in one nation.
