Back of napkin math is:

- 100ft.2 of solar panels (Qty: 5, off the shelf, ~3’ x ~5’ panels) = ~1kW of AC electricity (post-inverter, in low-sun Seattle)

- At the roof, this represents 10 wires and ~8 roof penetrations (racking lags through flashing into rafters)

AKA: simple setup, proven implementation

Questions:

- How many wires (points of failure) are in 100ft.2 of solar shingles?

- How many roof penetrations?

- How many roofer-electricians do you know?

- Why can we not just embrace existing panel technology and put them everywhere, yesterday?

Rant:

- We don’t need boutique renewable energy, we need ubiquitous RE.

- Elon, get your priorities straight. In the three years you’ve been trying to figure out the perfect solar status symbol, you could have installed megawatts of photovoltaics.
