How much solar can a 20 foot container hold?

20 foot containers can expand from 3,000W of solar up to 6,000W. 40 foot containers can expand from 3,000W up to 12,000W of solar in the future. We love the strategically placed solar panels on top of the container roof - we've accomplished this secure mounting with our field tested RPS Scalable Ground Mount.

What is a 20 & 40 ft shipping container?

Our 20 and 40 foot shipping containers are outfitted with roof mounted solar power on the outside, and on the inside, a rugged inverter with power ready battery bank.
