Thin film solar cells on Kapton can be 1250+ W/kg.
Record power density 4300 W/kg AMO (1367 W/m²) Gossamer
Thin Film CP1 Polyimide/Amorphous Silicon (CP1/a-Si:H)
There are 20kg deployment booms for 400 square meters.
12kg of the CP1/a-Si:H can provide 50kw of power. The present
cost estimate for CP1/a-Si:H solar is $250 per Watt at the deployed array level.
The cost of the 250 kW (250,000 Watts) rigid cell solar power
arrays for the International Space Station was $600M. This is
comaparable to a cost of $62M for a 250 kW CP1/a-Si:H solar array
with Ultra-lightweight deployment. A $600M CP1/a-Si:H solar array,
of equal cost to the ISS solar array, would provide 2.4 MW (2,400,000 Watts)
of power with cost reductions for space fabricated for Aluminum/Graphite
composite tri-beam truss beam structural elements.
