The light collecting portion of solar panels is extremely light weight. https://www.amazon.com/dp/B082FCZ4MD/ref=emc_b_5_t?th=1

59.2 by 26.5 inches or ~1 square meter Weight: 6.2 lbs.

If you looking at 12 square meters of space that’s 75 pounds though an integrated system would have plenty of options to save weight.

Solar panels are DC as are batteries so you don’t need an inverter.
