Why Every Rooftop Solar System Needs Energy Storage
John Petersen for Investor Intel: Rooftop solar is an odd duck. A consumer buys an expensive capital asset with the expectation that he’ll recover his investment through lower electric bills. As a matter of metaphysics, he’s decided to go into the power business with the primary goal of satisfying the most important and discriminating customer on the planet. The value proposition he currently offers his local electric utility is:
I’ll buy less electricity from you because of my solar panels, but I need you on standby 24/7 to supply my nighttime needs and fill any weather related power production gaps;
Since my solar panels will frequently produce more power than I need, I want you to give me credit for any excess power production, let me draw equivalent power from you when I need it, and structure it all as a tax free swap;
You can, of course, bill me for any difference between what I deliver and what I take;
I’ll have no duty to buy a fixed amount of power from you or deliver a fixed amount of power to you, but you must supply whatever I need and take whatever I don’t need; and
You will be required to pay all of the costs associated with weather related production gaps and pass those costs through to your other customers.

Scripps Vessel Proves Viability of Renewable Fuel on 14,400-Mile Voyage
Chris Jennewein for Times of San Diego: A Scripps Institution of Oceanography research vessel has demonstrated the viability of renewable fuel by traveling 14,400 nautical miles over a 16-month period on renewable diesel.
The R/V Robert Gordon Sproul used a hydrogenation-derived renewable fuel called NEXBTL Renewable Diesel developed by Neste Oil in Finland. The experiment began in September 2014 and ran through December 2015, during which time the vessel used a total of 52,500 gallons.
“Part of the Scripps mission is to protect the environment, and one of the most significant changes that we could make in our ship operations involved moving toward the use of cleaner, renewable fuels,” said Scripps Associate Director Bruce Appelgate. “As scientists, we know we need to develop sustainable means of powering our ships to address pollution concerns as well as to mitigate future increases in fossil fuel costs.”
Renewable biofuel is nearly carbon-neutral and produces cleaner emissions, thus decreasing greenhouse gas emissions and improving air quality relative to fuels derived from petroleum. Cont'd...

SolarCity pushing industry to 40% increase in useful lifetime of solar power installations
John Fitzgerald Weaver for Electrek: In a new report released by SolarCity, we are seeing that solar power systems have a usable lifetime of at least 35 years – 40% longer than the market expects. The key finding of the report is that power degradation (annual efficiency loss) of solar panels supplied to SolarCity is as much as 35% lower than for a comparable industry-wide selection of non-SolarCity panels, which are typically expected to last for 25 years. SolarCity feels it is the implementation of a stringent and industry-leading “Total Quality Program” that has driven this.
SolarCity is in the unique position of being one of the largest deployers of solar panels – from multiple manufacturers – in the world, and with their tens of thousands of systems connected to a central database they know realtime performance. In the study here, SolarCity looked at greater than 11,000 panels to determine their data points and come to their conclusion that their solar panels are performing well beyond expected industry standards.

Here's How Brexit May End Most British Wind Power
Andrew Follett for the Daily Caller: Officials from Britain’s wind industry are terrified their subsidies and tax incentives will end because of the U.K.’s decision to leave the European Union, according to a report by Reuters published Friday.
The report found that British wind companies, particularly ones that specialize in offshore wind power, are worried that Brexit places the government subsidies and easy access to financing at risk. The industry is deeply dependent on these subsidies to make projects more economically viable. Britain’s political uncertainty following the pending resignation of Prime Minister David Cameron means cuts to subsidies are likely. The Brexit could also make it much harder for wind companies to get loans from European banks, which could significantly slow the expansion of wind power. Cont'd...
Tesla applies for 6 new trademarks to sell solar energy under the 'Tesla' brand
Fred Lambert for Electrek: Last week, Elon Musk announced his plan for Tesla to acquire SolarCity and fold the solar installer’s operations into Tesla’s own business. The offer is still contingent on board approval and shareholder votes at both companies, but Electrek has now learned that the automaker is going ahead with trademark applications to sell solar products under its ‘Tesla’ brand.
According to trademark filings obtained by Electrek, Tesla’s trademark and copyright attorney at Cooley LLP, Ariana Hiscott, filled 6 new trademark applications for the company on June 22nd – the day Tesla announced the offer.
The trademarks applications range from solar cells and solar modules: “Solar energy equipment, namely, photo-voltaic solar modules for converting electronic radiation to electrical energy; and equipment for use in collecting and converting solar into electricity, namely, solar cells and inverters.”
To the installation and repair of solar panels: “Installation, maintenance and repair of solar panels and other equipment for use in converting solar energy into electricity; installation of solar energy systems and consulting related thereto.”
It also covers the monitoring of solar energy generation and the financing of solar installations. All applications are for the trademark “Tesla”. Cont'd...

BMW electric-car batteries to be used as home energy-storage devices
Stephen Edelstein for GreenCarReports: Tesla Motors was the first carmaker to branch out from selling electric cars to offering standalone battery packs for energy storage, but others have followed the company's lead.
Mercedes-Benz and Nissan have stated their intentions to enter the energy-storage market, and now BMW is jumping on the bandwagon as well.
At the Electric Vehicle Symposium & Exhibition 29—known as EVS29—held this week in Montreal, Canada, BMW unveiled an energy-storage system that uses battery packs from i3 electric cars.
Developed in concert with German firm Beck Automation, BMW's system is designed to use either new battery packs or "second-life" packs that have degraded too much for continued use in electric cars.
Battery packs that can no longer function in cars still have enough usable capacity for energy storage.
BMW has tested the concept over the past five years with various research projects, including a 2013 "micro-grid" project with the University of San Diego, and a 2014 collaboration in Germany with utility Vattenfall to use electric-car battery packs as buffer to help stabilize electricity grids.

IKEA of energy delivers clean, green solar power-plant in a box
Richard Kemeny for New Scientist: Here’s a bright idea for flat-packing. A German start-up has figured out how to cram an entire solar power plant into a shipping container. It has sent its first kits to off-grid villages in Africa, where they provide a new source of clean, affordable electricity after just two hours of assembly.
More than 620 million people in sub-Saharan Africa have no access to electricity, a situation that can keep people in poverty. And population growth means this number is rising. Those with access tend to rely on inefficient diesel generators, chugging along with crippling financial and environmental costs.
Despite that, diesel is standard for off-grid energy. “If there’s no diesel, there’s no electricity”, says Rolf Kersten of the start-up, Africa GreenTec in Hainburg, Germany, which shipped its first solar generator to Mali in December last year. Cont'd...
