  • 21 November 2014: Listen Up: Improving Solar Panel Output with Optimizers
    Solar panels keep getting more efficient. That's a great thing. But they can't communicate, can't adjust to environmental circumstances, and don't have automatic shutdown capabilities. Fortunately — and with apologies to the Farrelly brothers (who seem to have similar limitations) — solar panels aren't getting any dumber. Many of the newest solar panels are equipped with optimizers, either built into the junction box or attached as a separate component to the back of the panel. Microinverters (which convert the DC output of a panel to AC) provide the same basic benefits at similar costs; however, unlike microinverters, optimizers operate on the DC side of the system and are always connected to a central or string inverter.> <>

  • 20 November 2014: China Curtails Less Wind Energy in 2014
    Latest data from China's National Energy Administration shows that 8.85 GW of new wind power capacity was installed in the first nine months of 2014, bringing its total capacity to nearly 85 GW, a year-on-year increase of 22 percent. Accounting for 6.6 percent of China's total installed power capacity, wind exceeds nuclear power in installed capacity and electricity production, has become the third major power source following coal and hydro.> <>
  • 20 November 2014: Green Benefits: Companies Now Offer Solar Energy Programs for Employees
    Vote Solar may be best known for our work advocating for state-level policy, but we've also been hard at work helping tackle solar soft costs head on through our GroupEnergy program. Our take on the solarize community purchasing model focuses on helping existing groups — think coworkers, clubs or congregations — pool their collective buying power to go solar at home.> <>
  • 20 November 2014: California’s Reserve Fund Won’t Lift the Financing Boot from PACE’s Neck
    Earlier this year, the state of California announced a $10 million loan-loss reserve to solve the Federal Housing Finance Agency’s severe restrictions on using property-tax based financing for energy efficiency and renewable energy on residential property. It’s a great concept, but evidence from on of California’s best property assessed clean energ> <>
