Why You Should Think Seriously About Going Solar
Time.com – June 3, 2015 – John Garskof
If you’ve been noticing more solar panels lately, you’re onto something. While only one in 100 houses has them, says David Feldman, senior financial analyst at the National Renewable Energy Laboratory, that’s 46 times as many as a decade ago. Some of that fast growth is due to a federal tax credit that is worth 30% of installation costs (and which is set to expire at the end of 2016). Some is owed to the fact that Chinese factories are churning out photovoltaic panels nearly as fast as flat-screen TVs. And a third catalyst is a new breed of financing options that virtually eliminate the tens of thousands of dollars in upfront costs of going solar.
Here’s what you need to know to harness the power of the sun:
How Solar Power Works
Going solar doesn’t mean going off the grid. You stay connected to the electric company via a two-way meter the solar company installs. That lets you buy juice as needed. When panels produce excess wattage, it goes back into the grid, and you’re credited for the amount. Though you could eliminate your electric bill, the typical residential installation yields 75% to 90% of the household’s power needs, says Chris Doyle of Dividend Solar, a solar financing company.
There’s enough sun in every continental state to turn a roof into a power plant. But what makes the solar math work is a combination of high electric rates and financial incentives from your state and utility.

How to Pay For It
A solar power system costs $10,000 to $30,000 after the federal tax credit—depending in part on the size of the system required. That investment yields monthly electric savings of $100 to $200, which is most of the average household’s electric bill. So you should recoup your investment in five to 10 years. If you have the cash and plan to stay put, this gives the best ROI.
A solar lease is an alternative that requires little or no money upfront. You pay the solar company a monthly fee or preset discount price for the power the panels generate. Though you can’t claim the tax break or any rebates, you’ll still save 10% to 20% on electric costs, typically $10 to $40 a month, says Jonathan Bass of installation firm SolarCity. Also, most leases include a maintenance contract in the price.
The newer option of a solar loan offers the perks of leasing—no cash upfront, sometimes a maintenance contract—with greater savings for most people, Feldman says. Interest rates range from 3% to 6.5% for 10- to 20-year loans. After factoring in loan payments, you’ll cut your electric bill by 40% to 60%, about $40 to $120 a month, assuming you put the tax credit toward your loan, says Vikram Aggarwal, CEO of EnergySage.com. You’ll reap even more once the loan is paid off, and panels typically last 25 years.
However you pay, install panels only on a fairly new roof, so they won’t have to come down for roof repairs—and make sure to do it before the write-off expires.
