As example the SM +10 major battery as beam weapon outputs 3GJ and thus you likely need a lot more than that to fire it due to inefficiencies.
Total Solar radiation at distance of 1 AU is on average 1.36 kw/m^3, so with a super science 73.5% efficiency(where normal efficient solar cell today is maybe 20%) you would have 1kw/square meter and to get 1 GW(allowing you to shoot maybe every 5-15 seconds depending n your weapon efficiency) you would need a solar panel 1 km by 1 km(SM +19)
And going to mars you would need more than double the area.
So adding solar mirrors you would thus need similar areas of mirror...

- Does that mean each solar mirror system reflecting on a solar panel array provides the same energy as another solar panel? (Mirrors are cheaper than solar panels, after all.)
- Is there a maximum power limit that a solar panel array can handle without damage?
- Since both are “exposed systems”, could they be made retractable like exposed radiator panels (perhaps by doubling the cost)?
