"There are a lot of options available, more than people generally think of," says Daniel Connell, a designer who shares open-source, low-cost alternative energy plans and tutorials on his website OpenSourceLowTech.
"An offgrid home is designed for low electrical draw," Betz says.
Betz estimates that for "just a few lights and charging a laptop," you could set up an off-grid energy system for between $1,000 and $3,000, but a system for a small homestead usually costs somewhere between $5,000 and $7,000. A back-up generator will cost an additional $500 to $5,000 depending on its capacity.
"Most systems we sell for a full-time off-grid household start around $10,000," Betz says. "We don't do a lot above $20,000." Even so, budget matters. "The people that really struggle are the ones on a really tight budget who can't afford the system they need," he adds.
