DFPS is always willing to stretch out and make the extra effort for our clients. So when Lloyd's Electric Service reached out and asked us if we had a way to pull off a long term time-lapse, off the grid, we did our homework and we made it happen.
Long term time-lapses can present challenges, chiefly power. In this case, we did not have access to AC, but we did have a location primed for solar power generation. In fact, the time-lapse we were recruited to produce was of the construction of a new solar field on Pellissippi State's Hardin Valley campus.
We designed our time-lapse enclosure around a solar battery maintainer and a 12V sealed lead acid battery. The enclosure is a repurposed pelican style case. A little rotary tool action, epoxy and sealant later, we had an enclosure suited to fit a Panasonic GH4, lens, battery and power equipment.
Right now the enclosure is perched atop a light pole in a PSTCC parking lot, snapping away dutifully. We'd like to think every problem we encounter is as solvable with a similar application of ingenuity and determination.
