A New Ground-Mounted Solar Array

Posted on May 06,2015 by user-756436 in photovoltaic

I’ve lived in an off-grid house for the past 39 years. Since I make my own electricity, my electricity costs are much higher than those of most Americans. Because of my off-grid lifestyle, I often lack perspective when I try to help people who ask questions about ordinary energy choices. (I’ve had to compensate for my lack of relevant experience by undertaking anthropological studies of my grid-connected neighbors.)

Solar Energy Costs Fall in 2013

Posted on May 06,2015 by ScottG in distributed generation

Prices for photovoltaic (PV) systems fell by between 12% and 19% last year, and should drop another 3% to 12% this year, a joint report from two national laboratories says. The trend toward lower prices is keeping the country on track to meeting the targets of the U.S. Department of Energy's SunShot initiative, the report said, which forecasts a price reduction of 75% in the cost of solar-generated electricity between 2010 and 2020, to 6 cents per kilowatt-hour.

Report Says Walmart Owners Undercut Solar Growth

Posted on May 06,2015 by ScottG in photovoltaic

The family that owns Walmart, the country's biggest retailer, has spent millions of dollars to slow the growth of residential photovoltaic (PV) systems while making public claims about its commitment to sustainability, a non-profit research organization said in a report published this month.

Wisconsin Utility Seeks New Fee for Renewables

Posted on May 06,2015 by ScottG in photovoltaic

A Wisconsin utility is seeking regulatory approval for a revised rate structure that adds new fees for customers who generate some of their own power with wind, solar, and other renewable energy systems, and cuts the amount of money they are paid for excess electricity through net-metering. We Energies' proposal would hike the fixed service charge (what it calls a "facilities charge") for all residential electric customers from $9 to $16 per month.

Austin, Texas, Will Boost Solar Output

Posted on May 06,2015 by ScottG in Austin

The Austin, Texas, city council has passed a resolution that requires a total of 800 megawatts in new photovoltaic (PV) within six years, a move that would make Texas one of the top 10 solar electricity producers in the country, Greentech Media reports.

Vermont Utility to Develop New Grid Technology

Posted on May 06,2015 by ScottG in battery storage

The largest electric utility in Vermont has announced its intent to offer a variety of new products and services to its customers and develop a network of micro-grids through the state that offer more reliable service than the existing "legacy grid system." Beginning in the city of Rutland next year, Green Mountain Power said it would partner with NRG Energy to develop an advanced distribution grid that could serve as a model for expansion to other parts of the state later. The utility has some 265,000 residential and business customers in Vermont.

Solar Gets A Big Boost in Hawaii

Posted on May 06,2015 by ScottG in Hawaii

Hawaiian Electric Companies (HECO) has announced a plan to triple the number of solar electric panels in the state by 2030 and take a variety of other steps that would lower power bills for state residents by 20%. Utility Dive reported the move would increase the proportion of renewable energy from its current level of 18% to 65%, the highest in the United States.

Bank Predicts Shift in European Power Picture

Posted on May 06,2015 by ScottG in distributed generation

The world's largest bank is advising investors and clients that innovations in photovoltaic (PV) technology and rapidly falling costs for batteries and PV equipment will eventually make large, centralized power generating stations in Europe obsolete. UBS bank, based in Zurich, earlier this month produced a lengthy briefing paper that predicts that an investment in a combined electric vehicle / PV installation / battery system would pay for itself in as little as 6 to 8 years by 2020, without any subsidies.

PV Cost Reaches Grid Parity in 11 States

Posted on May 06,2015 by ScottG in grid parity

For people in 11 states and the District of Columbia, electricity produced by photovoltaic (PV) arrays costs no more than electricity purchased from a local utility, according to the Union of Concerned Scientists (UCS). Mike Jacobs, the UCS's senior energy analyst, writes in a blog posted August 20, that more than half the states in the country could reach what's called "grid parity" by 2017.

Solar Industry Sees Potential PV Panel Shortage

Posted on May 06,2015 by ScottG in photovoltaic

The global photovoltaic (PV) panel industry is facing the first shortage of panels in eight years as installations continue to pick up, according to a report in BusinessWeek. The article said the industry could install as much as 52 gigawatts of solar panels this year and another 61 gigawatts next year. That would be more than seven times the capacity of the PV equipment installed just five years ago, and substantially above the 40 gigawatts installed last year.

Utah Utility Seeks Fee for Net-Metered Customers

Posted on May 06,2015 by ScottG in net metering

Net-metered residential solar customers of Rocky Mountain Power in Utah would see a new $4.65 monthly "facilities charge" on their bills under a plan now before state utility regulators. Like other electric utilities around the country, Rocky Mountain Power argues that it faces fixed costs for maintaining the grid regardless of how much electricity it sells. Customers who have photovoltaic (PV) arrays on their roofs, it says, avoid paying their full share.

A New Life For an Old Landfill

Posted on May 06,2015 by ScottG in photovoltaic

For 23 years, the landfill in Scituate, Massachusetts, accepted municipal solid waste, construction debris, and residue from a nearby wastewater treatment plant. When the dump was finally capped in 2000, the city faced the same problem that a lot of communities do as they convert landfills into transfer stations: Just how could this piece of land be put to good use?

Solar Loans Are Getting Easier to Find

Posted on May 06,2015 by ScottG in financing

Homeowners looking for a way to finance new rooftop solar systems now have more options than local banks and credit unions. SunPower Corp., the country's second-largest maker of solar panels, said on June 16 it had worked out a $200 million loan agreement with Admirals Bank that would fund residential solar projects over the next two years, according to a report at MarketWatch.

An Energy-Self-Sufficient Community

Posted on May 06,2015 by Andrew Dey in biogas

From a distance, Feldheim looks like many other rural villages in Germany: a cluster of buildings surrounded by farmland and forests. The backdrop includes numerous wind turbines, but that’s not unusual in Germany’s breezy north. What is unusual is that there are two signs welcoming visitors to Feldheim: the typical yellow sign that is found at the edge of every village, and another in blue and white announcing that Feldheim is an “Energieautarker Ortsteil,” or an energy self-sufficient district.

Are Solar-Plus-Battery Systems Coming to a Neighborhood Near You?

Posted on May 06,2015 by ScottG in battery

Solar-plus-battery systems that combine photovoltaic panels and lithium-ion batteries are helping a number of commercial electricity customers cut their power bills, but any widespread spillover to the residential side of the market looks to be some time away. Two solar installers, SolarCity, and SunPower, are offering the systems to residential customers, yet the numbers in the pilot programs are very modest.

New Solar Fees Proposed in San Antonio

Posted on May 06,2015 by ScottG in net metering

Trustees of San Antonio's municipally owned electric utility have approved a plan to award $21 million in new solar rebates, retain the current net-metering rules for rooftop photovoltaic (PV) systems, and develop a solar leasing program for utility customers who are unable to install their own PV systems. At the same time, the CPS Energy Board of Trustees wants two new fees to pay for it: a one-time $450 interconnect charge for new residential systems, plus a monthly fee of $1 per kW of PV capacity. Existing customers would be grandfathered.

Can We Power Our Car With the Sun?

Posted on May 06,2015 by AlexWilson in electric vehicle

I’ve written about a lot of the features we included in our new house in Dummerston, Vermont, to reduce its energy use and environmental footprint, but there’s another one — a big one — that doesn’t really relate to the house.
