The accumulation of dirt on solar panels has been proven to reduce their efficiency significantly, placing a heavy burden on owners to keep the panels clean in order to ensure project viability. U.K.-based Opus Materials Technologies says it has received funding that will help it validate a new coating that will allow solar panels to clean themselves. [...]
“Happy families are all alike; every unhappy family is unhappy in its own way,” Leo Tolstoy, Anna Karenina. In the solar industry, strong markets are alike in that they have incentives, subsidies and/or mandates to drive growth and adoption but also a fair amount of political and economic risk and every weak or collapsing market is alike in that it no longer has incentives, subsidies and/or mandates to drive it and its political and/or economic risk has become a reality.
A weak market [...]
It’s that time of year again: holidays! Until 2018 begins, we try to set aside some extra time for family, eat delicious meals together, exchange gifts and generally close out the year with good wishes and good intentions for the next year.
While Renewable Energy World is a business-to-business publication for the global renewable energy industry, we occasionally get press releases and notifications about interesting inventions that are designed for the general public. And as the holidays appr [...]
Despite the Environmental Protection Agency’s announcement that the Clean Power Plan is being repealed, the attractive cost of renewables and improvements in battery storage technology mean that wind- and solar-generated power are here to stay. [...]
Solar manufacturers are being battered by higher costs and smaller margins after an unexpected shortage of a critical raw material. Prices of polysilicon, the main component of photovoltaic cells, spiked as much as 35 percent in the past four months after environmental regulators in China shut down several factories. [...]
Investment banks aren’t interested, and neighborhood banks just don’t understand. So where is someone who has a great commercial solar project supposed to get funding? [...]
There’s long been a Catch-22 about residential solar: despite staggering market demand, it’s been hard to make money doing it—until now. Sunrun Inc. said Wednesday that it’s cash-flow positive. And Blackstone Group LP-backed Vivint Solar Inc. expects to hit that mark next year. [...]
This week, we review the spectrum of backup power solutions from generators to home battery backup power systems connected to solar. I’ve been installing home battery backup power systems on and off for 20 years. [...]
Black Hills Energy has proposed rates that would increase fixed charges for all residential customers and put net metered solar customers in a separate rate class that would have to pay even more. COSEIA filed testimony opposing the proposed rates, which increase fixed charges by 54 percent for net metered customers, claiming they are discriminatory and seek to undermine solar generation in Colorado.
However, the Office of Consumer Counsel, which receives tax dollars to represent ratepayer [...]
Over the summer about 33 customers in Pacific Gas and Electric’s (PG&E’s) territory started a new journey with their utility. PG&E is hoping that through this and other pilot projects, it will learn how responsive batteries, solar PV and smart inverters are when they receive a signal from the utility. [...]
Over the past few months we’ve experienced a solar eclipse, several devastating hurricanes, another under-construction nuclear plant shutdown, and a backwards-looking Department of Energy Grid Reliability study.
Since unveiling its solar roof tile designs a year ago, Tesla has been testing the product, which CEO Elon Musk says is going to be a significant part of the company’s business down the road. [...]
Solar entrepreneur Bill Gross, the CEO of Edisun Microgrids, has successfully penetrated the commercial and industrial solar market segment with dual-axis trackers, promising a 30 percent performance boost for a cost increase of only 10 percent compared with a standard fixed-tilt PV installation, at optimal U.S. locations, he says. [...]
Listen to Blake Jones and Aaron James discuss solar loans and the decisions consumers are making about financing today, new financing options and services, and the question of transparency in the solar loans market. [...]
In a hearing held today, October 31, the U.S. International Trade Commissioners announced their recommended tariffs, quotas and other recommendations for solar modules imported into the United States from anywhere else in the world. [...]
The solar PV industry is at a high degree of capacity utilization in 2017 driven by strong demand in China for PV deployment. Globally from 86 GWp to 92 GWp is on track to be installed in 2017. Currently the industry has 92 GWp of manufacturing capacity and at the beginning of the year there was 3 GWp of inventory on the supply and demand sides. [...]
Tesla Inc. is preparing to bundle about $340 million of solar power purchase agreements and leases into a bond offering. [...]
Utility customers in Ohio and Nebraska are among those taking advantage of a new and simpler technique for connecting solar arrays and other renewable energy systems to the grid. [...]
The prospect of using solar power on a temporary basis, including for disaster response and recovery, is not new, of course. Indeed, Hurricane Hugo in 1988 is believed to be the first time that solar power was used for relief in the aftermath of a natural disaster. [...]
In 2013, the California Independent System Operator published a chart that is now commonplace in conversations about large-scale deployment of solar PV power. The duck curve—named after its resemblance to a duck—shows the difference in electricity demand and the amount of available solar energy throughout the day. [...]
SunPower Corp., the second-largest U.S. panel manufacturer, arranged more than $53 million in financing for residential-solar installations. [...]
Considering the reputation of crowdfunding and also the state of the EV startup scene, which hasn't delivered in a while, it's pleasantly surprising to see some actual progress with a new electric car concept. After a successful crowdfunding effort, German startup Sono Motors has unveiled the Sion, a battery-electric car partly powered by solar power with onboard solar cells, earlier this year. [...]
Big solar farms helped create a power-grid predicament in California. And now they’re offering to help solve it. Solar panels have proliferated in the Golden State, flooding the grid with power supplies in the middle of the day when the sun’s out — and then quickly vanishing after sunset. [...]
Solar leasing promoters have long claimed that electricity costs will keep rising, but we haven’t see this happening – yet. Actually, almost all of the standard generation sources are benefiting from lower costs – natural gas is low, coal is low, and nuclear is… well it’s not dramatically more expensive than it has been. There is no doubt in my mind, however, that prices are going to go up. [...]
