The remaining 11% of 5% would need about 8 seconds to generate more energy than humanity currently generates in 10,000 years.

Luminosity of the sun: ~380 yottawatts (3.8 * 10^26 watts)

Sunlight conversion efficiency of a silicon based solar panel: ~20%

A Dyson swarm around the sun built with silicon solar panels: ~76 yottawatts

A Dyson swarm around the sun where 5% of the panels work: ~3.8 yottawatts

The leftovers from a Dyson swarm around the sun where 5% of the panels work and 89% of the output has been used for interplanetary yachts: ~418 zetawatts (4.18 * 10^23 watts)

Primary power production on Earth: ~20 terawatts (2 * 10^13 watts)

10000 years times 20 terawatts is 10000 * 365.25 * 24 * 60 * 60 * 10^12 = 3.16 * 10^24 joules

Since a joule is just a watt-second, it takes 7.6 seconds for that 418 zetawatts of leftover Dyson swarm output to match up to 10,000 years of current human energy consumption.
