Right - Solar really just front-loads the energy costs of the building. You pay for ~5-10 years of energy up front, and then recoup that investment over the next 30+ years, coming out ahead in the end. You could argue that this sort of policy is a win-win in that it both reduces the longer term cost of housing (both for the first and subsequent owners) and also reduces the amount of net energy required (saves on new power plants, carbon).
- shortstuffsushi 8y agoSerious question -- isn't the lifetime of solar panels (or ancillary equipment) significantly less than 30 years? A quick Google looks like 15 years ish? I have never owned a home (or lived in one with solar), so I'm not sure of the actual typical mileage.
- sxates 8y agoThe panels on my house are warrantied for 25 years, and expected to last years beyond that. There are no moving parts, not much to degrade, so the useful life is quite long. Though I expect in 30 years the newer panels will be more efficient and super cheap.
