  • SolarCity Broadens Its Financial Reach in the Barely Tapped Residential Market
    Residential solar has soared in the past several years, with installation demand expected to soon surpass 1 GW of capacity. Much of this growth is due to the introduction of solar leasing. SolarCity, a major player in the residential solar leasing space, recently introduced new mechanisms to get more customers on board the solar train, and was at Solar Power International this week to discuss where the industry is headed.
  • Australia Seeks to Reduce Renewable Energy Target to ?Real? 20 Percent
    Prime Minister Tony Abbott?s government will negotiate with the opposition to cut Australia?s renewable energy target and exempt industries such as aluminum and copper smelting.
  • Viable Battery Backup for Rooftop Solar Still Years Away
    Using batteries to retain energy from rooftop solar systems will be too expensive for at least two years, according to industry executives.
  • Suntech Back from Dead, Eyeing 1.5 Gigawatts in Solar Shipments
    Wuxi Suntech Power Co., the solar manufacturer acquired earlier this year by Shunfeng Photovoltaic International Ltd., plans to ship almost twice as many modules this year, in the latest sign of a rebound.
  • Local Solar Rules Can Save You Big Bucks
    The price of an average U.S. home solar power system is about $20,000. (That?s before a 30 percent federal tax credit and any state, local and/or utility incentives.) If the price were to drop to $17,000, or even $16,000, would you be buying?
  • Evaluating Powerful Batteries for Modular Grid Energy Storage
    Sandia National Laboratories has begun lab-based characterization of TransPower?s GridSaver, the largest grid energy storage system analyzed at Sandia?s Energy Storage Test Pad in Albuquerque, N.M.
  • California?s Conservation Proposal Kneecaps Utility-scale Solar
    Six years in the making, state and federal agencies released five options with a ?Preferred Alternative? draft for the Desert Renewable Energy and Conservation Plan (DRECP), potentially kneecapping development in the best solar region in the U.S. by cutting off previous access to public lands and reducing eligible acreage by two thirds.
  • Renewable Energy Contractors Benefit from PACE Financing
    One third of all energy is wasted. Is PACE the solution? According to current energy data, commercial and industrial buildings use about 60 percent of the energy generated in the U.S. and about a third of this energy, especially in older buildings, is wasted due to inefficiency. But how do we know which third, and what can we do about it? The answe
  • Designing Reliable, Cost-effective Wind Turbine Shaft Systems
    A wind turbine?s main shaft requires a reliable bearing for operation. Some bearing designs have been known to fail prematurely resulting in costly maintenance repairs. Recent upgrades and advances in bearing designs increase reliability, and ensure main shaft stability. Selecting the proper bearing is beneficial to a wind turbine?s overall performance.
  • SPI Slideshow Day Three: Seen on the Tradeshow Floor
    The last day of Solar Power International tends to be a little more casual. Exhibitors, exhausted from frenzied activity over the first two days, can take a step back and reflect a bit. Check out our slideshow for more scenes from the tradeshow floor.

  • Community Solar Allows Utilities to Adapt, Thrive as Energy Landscape Evolves
    Adaptability is the key to survival ? both in nature as Charles Darwin observed, and in the business sector. As the solar industry continues to flourish, utility companies across the U.S. are beginning to witness how the traditional electric grid is transforming. As tens of thousands of residents have solar photovoltaic (PV) panels installed on the
  • The Next Revolution: Discarding Dangerous Fossil Fuel Accounting Practices
    The green revolution and, in particular, renewable energy products such as solar power, wind turbines, geothermal and algae-based fuels are not waiting for viable technology ? it already exists in many forms. What they are waiting for is a massive sea change in our antiquated financial accounting systems.
