Photovoltaic rocks! Look ma! No power used!
I recently added 15 new photovolatic panels to my solar power array. My daily "net power" consumption has now dropped to zero. I produce "excess" power during the day which is sent back out to the Hawaiian Electric Company grid. They use the power elsewhere and give me credit for the power they consume. Then at night or on cloudy days, I use up the credit. My minimum bill is $18.26 which is the "connection fee."
