Is Solar Worth It? New Study Says Yes, With Incentives
Home buyers will pay for solar, a new study from Lawrence Berkeley Lab says, but the incentives are important to make it economical.
Examining home sales from 2001 to 2009 in California, researchers at the lab found that home buyers will pay approximately a $5.50 a watt premium for homes with a solar system. That corresponds to around $17,000 for a 3.1 kilowatt solar system, the report stated. (Feast on the full report and the Hedonic Model Reports here.)
The net costs of these systems, after federal and state incentives, came to around $5 a watt. Homeowners, of course, also enjoyed the benefit of power from their panels. Solar, thus, provides a net benefit to homeowners as long as the incentives are factored in. The price for solar continues to plummet too. Attorney and reader Jason Jungreis just wrote in to say he got solar put on his roof for $3.80 a watt, including federal, state and San Francisco incentives.
The study helps bolster an argument made for years by solar installers and realtors. Namely, that solar adds to a home's price. The study examined 72,000 homes sales and approximately 2,000 of the homes had PV systems. The premiums ranged from $3.9 to $6.4 per watt.
Strangely, the premiums for solar on new homes was lower than the premium fetched for new solar systems on existing homes. Solar systems on new homes only fetched around a premium of around $2.3 to $2.6 per watt. The premiums on systems for existing homes came to $6.7 to $7 a watt. Maybe it was the fact that solar was a standard, and hence less exciting, feature on older homes. Maybe it made the new homes more interesting.
Approximately 2.1 gigawatts of solar have been installed nationwide. Last year alone, 880 megawatts went online in the U.S., stated the report, citing data from SEIA and GTM Research, up from 435 megawatts in 2009. 30 percent of the 2010 total were put on residences. California has 100,000 PV systems and 90 percent are on homes.

Melting Sea Ice Leaves Arctic Vulnerable to Erosion
Most of the storms at the edges of the Arctic Ocean occur in the autumn. If the warming climate keeps coastal waters ice-free after summer ends, these storms can dig deep into the permafrost, according to a report issued this week by the International Arctic Science Committee.
