Making Solar Affordable

摘要

You would think everyone would want to capture the free energy provided by the sun. Yet since its initial burst in the 1970s, solar energy has spread remarkably slowly, largely due to the upfront cost of solar panels. Just five years ago, installing photovoltaic (PV) panels could cost $40,000; today that same installment would cost $25,000 to $30,000 and take eight to 10 years to pay for itself, according to Tony Eason, owner of Elektron Solar (elektronsolar.com).
