This is the first and only UL-listed, 120-volt, plug-and-play solar kit in the world, according to SpinRay Energy. The DeckPower120 comes with one, 240-watt solar panel and can be hung on a deck or elsewhere outdoors using a simple mount bracket. The system allows for up to 1,300 watts of AC power with five solar panels and should qualify for available federal (and sometimes state) tax credits.
Southwest Windpower, maker of the small-wind turbine Skystream, just announced a refreshed Whisper line of turbines for battery-charging applications including off-grid residential homes. The Whisper 100 (7′ diameter) has the potential to generate up to 100 kWh per month at 12 mph; the Whisper 200 (9′ diameter) has the potential to generate up to 200 kWh per month at 12 mph; and the Whisper 500 (15′ diameter) has the potential to generate up to 538 kWh per month at 12 mph.
California-based Sunrun and Harris Interactive recently announced the results of a survey of 2,211 adults (1,475 homeowners) about the cost and desirability of installing a home solar system. The main sound bite is the one-liner that “97% of Americans overestimate the cost of going solar,” as well as the stat that “nearly 8 out of 10 of those who do not already have solar panels say they would install solar if cost were not a factor.”
A company called Solyndra pioneered the solar tube but this new invention by UK-based Naked Energy may just take cylindrical solar to a whole new level. Called Virtu, the product includes an integrated photovoltaic cell in a vacuum tube to generate both electricity and warm water at the same time. The setup keeps the PV cool to optimize energy production and maximizes space with a combined PVT solution.
Letting the sun’s rays reach your home’s interior rooms, or down to lower level, is a challenge on any project, and virtually impossible without cutting a large hole in your roof. But now, Solectric offers an electronic skylight that promises the next best thing — interior lighting that is powered by the sun and can be rendered at the same color temperature.
