If you unfold it, it takes up a lot of room. I guess you can unfold it on a deck or something, when you are not out there yourself using the space.

Forgetting to batten down this design when bad weather comes could be a very expensive oversight PV solutions for the home should be ’set it and forget it’.

If you want it to collect energy it needs to be unfolded. It also doesn't look very stable (wind?) if not bolted down, which means it's about as portable as any other solution... Not to mention it would have to be wired up to the charge controller etc. "I could see construction crews rolling these suckers off of trucks and using them to power machinery." Huh, so how much energy does one of these things generate... hmm in full sun at central latitudes it probably has the potential for 1000watts per square metre... with average PV efficiency of say 13% that is 130watts per square metre... so to power a 1000watt circular saw you would need say 10 square metres of panel and a big heavy inverter... or you could just bring along a generator... say if it's cloudy for example... Overall it's a _basic_ design of PV rack, nothing more... Something I'm missing? How does this save space?

It also doesn’t look very stable (wind?) if not bolted down, which means it’s about as portable as any other solution… Not to mention it would have to be wired up to the charge controller etc.

Something I’m missing?
