The residential solar market is still at the lift-off stage, but Swedish home furnishing giant Ikea already is looking at a future when consumers could roll through the checkout lines with ready-to-assemble solar-power systems.

Ikea's pledge to invest €50 million ($77 million) in greentech points to a vast new market in which people would make more buying decisions that reduce their carbon footprint and allow them to use energy efficiently.

The company plans to invest in companies developing products that it could carry in its stores, including solar panels, energy-efficient lighting and water-purification kits (see Green Light post).

To be sure, consumers already can replace incandescent bulbs with the energy-saving compact fluorescent (CFL) variety, or opt for other household items made of recycled materials. Stores also offer solar-powered garden lights, radio and even mosquito repellent (it emits a high-frequency sound wave).

But many of these items are sold in specialty stores and online sites and are not always affordable. Homeowners who want to install solar panels largely have to pay others to do it.

A growing number of investors are betting on renewable-energy technologies that could show up in Home Depot or Wal-Mart one day.

Morgan Stanley Principal Investments has put $20 million into G24 Innovation, a U.K. company that launched a solar-powered cell-phone charger last year and plans to begin selling solar-powered LED lights this year (see Funding Roundup: Solar, Biofuel, Batteries and More).

Berkeley, Calif.-based Better Energy Systems, which has developed palm-sized solar-power chargers for portable gadgets, last month raised $5 million from TBL Capital (see Funding Roundup: Solar Still Reigns). Sold under the brand Solio, the chargers can be plugged into a standard wall outlet and use lithium-ion batteries to store electricity.

Apple also is following the trend. Four Apple employees in May filed a patent for integrating solar cells into portable devices such as iPhones and iPods (see Charge Your iPhone In the Sun).

Aside from consumer products, investors are putting millions into plenty of other renewable-energy companies.

Ernst & Young just released its second-quarter venture funding report, which showed that U.S. investments in cleantech companies rose to a record $961.7 million, up 83 percent from the same quarter in 2007 and 41 percent from the first quarter this year (see Cleantech Investing blog).

  • Petratherm, which is traded on the Australian Stock Exchange under the ticker "PTR," won a Aus$57 million ($50.67 million) commitment from TRUenergy for its Paralana geothermal project in South Australia. The deal would enable TRUenergy, also in Australia, to own up to 30 percent of the Paralana project over time, provided that Petratherm hits certain milestones. The project is in the exploratory stage, and two wells are scheduled to be drilled later this year.
