    I doubt they put out much power at all compared to modern panels. Solar back then was a pipe dream, we didn’t have the battery technology to store the energy and the panels had a lower voltage and could supply less current.

    I have a 100w foldable panel for camping that at >= 20% efficiency is probably double what the 90s panels could do.

      In the 90s, rooftop solar was around 10-15% efficient. Now rooftop panels are closer to 20%.
