Heck I barely do!
I'm curious if anyone has stats on what percentage of houses have an unobstructed southern roof (for those in the Northern hemisphere)? My house has seasonally adjusted nanotechnology self-replicating shade "panels" that block considerable sunlight in the spring and summer months (MTBF: 100+ years). The big downside is cleaning up the unused panels in the autumn.

'No one saw Tesla's solar roof coming...' https://en.wikipedia.org/wiki/Solar_shingle Solar shingles, also called photovoltaic shingles, are solar panels or solar modules designed to look like and function as conventional roofing materials, such as asphalt shingle or slate, while also producing electricity. Solar shingles are a type of solar energy solution known as building-integrated photovoltaics (BIPV). There are…
Are there existing solar shingles that look like conventional roofs? Otherwise, maybe that was what made those solar shingles fail to find a market.
I think it's interesting looking at it from the other end - as a homeowner, I can tell you that roofing is an expensive proposition. If this can be competitive with traditional roofing and have a longer life expectancy, I'd buy in a heartbeat. It has the potential to displace thousands of tons of asphalt shingles per year with the equivalent of recyclable glass, which is pretty fantastic. The embodied energy of produ…
I'm sure i'm not the only one who feels like this is possibly the iphone moment of Solarcity/Tesla: an old-ish idea, made sexy and tasty to consumers, together with technology reaching a tipping point(and also Musk again finding a way to maximally exploit government subsidies for clean tech.) The tesla car itself could count as well, but felt less "design driven" imo. If this fails, everyone will call it obviously du…
The government is literally just US....it's our money and a collection of individuals from among us who we've appointed to handle the general administration of us and the space we take up.
Why should American entrepreneurs, particularly ones doing such an outstanding job of moving technology in a positive direction, not get our financial support (a.k.a. the government's support)?
Who exactly is losing out when we support our own business initiatives with our own money?

I need to replace my roof and I've been quoted almost $20k. If these are within $5k of that price, then I will jump on it.
From my experience, the price of installing solar on 1/4th of your roof is more expensive than installing a full, brand new roof. Beyond that, not all parts of the roof are created equal for solar - some will generated much less energy than others. E.g. a neighbor's tree blocks a fair portion of our roof from the sun. You can already get a $0 electricity bill without having full roof solar. I can't see it being anyth…

Except one ingredient is missing: most people cannot afford one, even if they tried really hard.
I had serious misgivings when Tesla/SolarCity announced a switch of focus to building-integrated PV. Historically, BIPV is where a PV technology goes to die after it's failed to compete against incumbent module designs. But these have far better aesthetics than previous BIPV efforts. They look better individually and they aren't clumped in one odd shiny patch on the roof like past BIPV. Search for images of solar shi…
Is that really Elon Musk wants, monopoly ?
