Last week, electrician Hans Wekking's energy bill was $3, which includes the cost of charging his electric car.
Two weeks ago, Wekking installed eight solar panels on his house at a cost of $10,000.
“This shields you from any rate hikes. Once you've paid for the system, the electricity is free,” he said.
“So if there's any future rate increases — like gasoline keeps going up, so is electricity — so for 25 years you are producing electricity,” he added.
Wekking says the solar panels are not as effective in the darker months, but can still run a TV or laptop.Suggest a correction
