Wait. I have solar and love it. But if your electric bills over a 4 year period do not amount to the install cost of the solar, the technology used is meaningless? And because install costs do not decrease with more efficient tech, and things like the inverters are just as expensive, I certainly cannot pay off my system in 1 year. More like 10 years.
- ghaff 11y ago10-ish years are the kind of payback I saw when I looked into it. My electricity bill is about $100/month--so ~$1K/year is about the most I could save if I bought solar panels. Companies like SolarCity can make the math more complicated. And in all fairness they can probably take advantage of various breaks and subsidies I may not have access to as a consumer. However, it's like a car purchase. I'm skeptical that some lease agreement suddenly makes a purchase sensible that wouldn't be with a straightforward cash on the barrel buy.
- Retric 11y agoEnergy costs are a small fraction of installation costs. EX: You had someone walking around on the roof, which cost a lot more than the 200w or so they where burning doing so.
