Did some math on this. 100kw solar system is too big to fit on your roof and probably over 4x what it would take to generate 100% of your annual usage. You get 4 minutes of light. You make 6.5kWh of electricity assuming this reflected light is bright and overhead enough for your system to hit 100% of theoretical output for the full 4 minutes. At 20c/kWh, above the national average, you get about $1.25 by receiving the light.

Just napkin math but it really makes me question their business model.
