EGEB: Not illegal to offgrid in Florida; British coal dead; World’s largest solar thermal $3.9B; more

Site default logo image

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

Want solar panels? You still have to pay Florida – This article is wrong regarding going off grid. It is NOT illegal to go off grid in Florida – and you don’t necessarily have to pay the utilities if you want solar power. First point – it isn’t illegal to go off grid. A while back there was a court case in which a person tried to go off grid completely – solar, water and sewage. The local jurisdiction condemned her home saying it wasn’t habitable. She took them to court. The judge ruled that going off grid solar and water were acceptable. However, since the lady was still connected to the local sewage system – but had disconnected the service, she was still liable for costs. Additionally – since this particular jurisdiction had water+sewage interconnected, she wouldn’t be able to go off grid for water unless she installed a septic tank and managed her own sewage. Second point of the article – that is partially true – the electric utilities have lobbied to make ‘anti-islanding’ a thing. Your solar power system will shut off when the grid goes down so you don’t backfeed local poles. This protects line workers. Be careful the conspiracy we bite onto.

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

Decision makers are ‘compelled’ by value of solar-plus-storage – “They’re willing to trade the savings from the solar for the resiliency. So the school is still saving money on the solar-plus-storage system, they’re just not saving as much. Being able to trade dollars they didn’t have in the budget – the savings they created out of the solar – for this priceless public service, that’s a big deal.” Local power production, along with energy storage, is worth more than the monetary savings from solar electricity alone. After watching hurricanes debilitate local populations administrators are starting to wise up to the weaknesses of being dependent on distributed wiring systems. Energy storage – local batteries – are going to rule the world.

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

CAISO Regionalization, 100% Clean Energy Bills Stall – California hasn’t been able to push its 100% renewables bill – #SB100 – through just yet, and that means it won’t happen until – at the earliest January. “(SB100) is not going to move — there is overwhelming opposition to it. And there is not time to work that out,” Assembly member Chris Holden (D) said. One batch of opposition comes from unions who say a push toward 100% renewables will harm their job prospects. Another interesting push – ‘regionalization’ of CAISO, California’s main power grid management body, would allow California and other states to more easily trade renewable energy among themselves. Now, California will often export additional solar power to Arizona – slowly cleaning their grid – but not in an official and organized manner. Regionalization would help push that along. Of course – that bill doesn’t look like it will pass either.

The great nutrient collapse – In 2004, a landmark study of fruits and vegetables found that everything from protein to calcium, iron and vitamin C had declined significantly across most garden crops since 1950. In 2014, Myers and a team of other scientists published a large, data-rich study in the journal Nature that looked at key crops grown at several sites in Japan, Australia and the United States that also found rising CO2 led to a drop in protein, iron and zinc. Not only is CO2 increasing weather effects like hurricanes – it’s also lowering the nutritional density of your food. The mission to get clean energy and transportation is only that much more important.

DOE Officially Marks SunShot’s $1 per Watt Goal for Utility-Scale Solar – And you know what: its years early and doesn’t include subsidies. The DOE’s National Renewable Energy Laboratory (NREL) released new research today that shows the average price of utility-scale solar is now under $1 per watt and below 6 cents per kilowatt-hour. That’s higher than the record-breaking project bids we’ve seen in the U.S. and abroad in recent years. But that’s because DOE calculations for levelized cost of energy (LCOE) do not include subsidies — such as the federal Investment Tax Credit — and are based on the average climate in Kansas City, Missouri. Thank you SunShot, thank you China and thank you Obama.

Your trusty Commercial Solar Guy has sacrificed much to sneak out to the Mandalay Bay Convention Center in Las Vegas, Nevada for Solar power International 2017. The blue skies, colorful drinks and 90°F are really taxing my ability to stay focused on solar panels – but I’ll do my best to tell you about the coolest solar panel technology on the planet.

Pope says humanity will ‘go down’ if it does not address climate change – Pope Francis said the recent spate of hurricanes should prompt people to understand that humanity will “go down” if it does not address climate change and history will judge those who deny the science on its causes. “If we don’t turn back, we will go down,” Francis told reporters on Sunday on the plane returning from Colombia. This planet has suffered massive animal die offs in the past as a result of changes in the atmosphere. Humans are not special, other than that we can clearly see what is happening and we have a chance to react. We do have a choice.

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

US Residential Solar Market Forecast to Decline For the First Time – Last week, we saw that in first half of 2017 the USA set another solar volume record, but within that record is a decline in the residential market. This decline is mostly driven by a shift from solar leasing toward solar purchasing. As companies like SolarCity and Vivint start trying to improve cash flow versus selling large volumes of long term leases, their focus has shifted those large volumes toward a ‘higher quality’ product. This interesting dynamic is shown within the overall drop, in that cash purchases have increased, as well the broadness (number of states with solid volumes of cash purchases) of the market has increased. Yes, the press will show you headlines purporting the challenges of residential solar – make sure you read the details though.

Amish phone booths – McKenna trained a local high-school physics teacher to do installations. About 50 of them are off the grid. One lights up the gazebo in the local cemetery; others are phone booths meant especially for the Amish. Since religious principle dictates no electricity at home, they rely on the booths as a crucial link to the outside world.  The article is really about solar power in Trump voting areas, but the Amish piece caught my attention.

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

Your solar panels could power the neighborhood during a blackout – The team has created a number of algorithms that allow homes to disconnect from the grid, and use and share power from their renewable energy resources during an outage, all the while improving system reliability by up to 35 percent. Right now, in the USA if the power grid goes down – we have legislated that a solar power system, without a battery backup, will shut down. Meaning you will lose power as well. This is done to protect those working on the grid later on. Maybe its time to move beyond that? Distributed energy production means distributed energy power plants are coming. These algorithms will be part of that guidance.

Acciona and Spanish university claim world record solar generation measurement in Chile – “The peak power curve was obtained with an irradiance of 853 W/m2 and a cell temperature of 40.1oC.” The deserts of Chile are some of the best sunlight on the planet, and now it looks like we have evidence of them being the highest anywhere on the planet for this moment. Of course, the people that work these plants have to wear special gear to protect themselves from sunlight even in short time periods – maybe not the best place to build a home.

EGEB: Chinese ‘Solar Manhattan Project’ vs US Manufacturing; Windfarms survive Harvey; more

Site default logo image

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

The case for U.S. solar manufacturing – CEO of SolarWorld wrote a letter in support of trade sanctions against China government financed solar panel manufacturers flooding the global market. The fundamental argument: The Chinese government showered its industry with export-oriented subsidies, which the U.S. government two times determined to be illegal.  These producers also were found to be selling into the U.S. market at prices below production costs – an illegal practice called dumping. It is true – these specific sub industries within the broader industry have suffered. My question is – has the Chinese funding of below ‘market price’ solar panels hurt the US economy? Well – that answer is a clear ‘no.’ The broader US economy (and the globe) has far benefited from the Chinese ‘Solar Manhattan Project’ (otherwise known as small subset of a Chinese Five Year Plan) as the solar market as a whole is far larger than it would have been with a much slower pace of solar panel growth at ‘prudent’ profit margins… So, who wins in the broader game?

China makers to hike September contract prices for solar mono-Si wafers – China-based solar mono-Si wafer makers will raise supply contract prices in September by 2-3% from the current level, according to industry sources. It seems a large part of the world (India, Europe, and the USA) wants to sue China for such low solar panel prises. If all of these countries do put taxes on Chinese products, maybe China should increase their prices a bit, and keep a bit more of the profit at home for research/growth or in the supply chain to fatten up those profit margins. No point in letting all those taxes go to host countries.

Duke agrees to build 700 MW of solar, 50 MW of energy storage in FloridaIf approved Duke’s Florida customers will no longer be on the hook for costs related to the Levy County Nuclear Power Plant, which Duke has finally formally abandoned after cancelling the construction contract four years ago. In its place the utility plans to “construct or acquire” 700 MW of utility-scale solar over the next four years, as well as to build, own and operate 50 MW of battery storage and install 530 electric vehicle charging stations. In essence, because Duke failed getting a nuclear plant built – and it was sued because of huge amounts of money that were going to be put on the shoulders of customers due to that failure – Duke is now offering a settlement of building solar/charging stations/energy storage. Maybe there is a lesson here?

First tanker crosses northern sea route without ice breaker – The specially-built ship completed the crossing in just six-and-a-half days setting a new record, according to the tanker’s Russian owners. “Previously there was only a window of navigation from our summer to autumn, but this ship will be able to sail westwards from Sabetta which is the Yamal energy port, all year round and eastwards from July to December,” said Sovcomflot spokesman Bill Spears. “Before the northern sea route was only open for four months and you had to have ice-breakers – so it’s a significant development.” For hundreds of years, Europeans sought a ‘Northwest Passage‘ to shorten the trip to Asia. Many died. Now, with the arctic warming and the ice melting, we’re able to make this trip year round. This ship does have some ice breaker capabilities – but they’re limited. Hard evidence of global climate change.

French island tenders push down solar-plus-storage prices by 40% – The 67 projects that include PV panels and batteries attained a guaranteed purchase price for their generated power of €113.6 (US$133.97) per MWh. In June 2016 a 52MW tender for island territory solar-plus-storage projects awarded feed-in tariffs (FiTs) at a weighted electricity price of €204/MWh (US$229.77/MWh). Power prices on the islands is set at around or over €200 per MWh, the ministry said. Small projects coming in at these prices will put the fossil fuel industry out of business in remote locations like this – and there are billions worth of revenue of remote locations. Customer pricing fell from $0.20/kWh to $0.13/kWh – solar plus storage just dropped their local retail pricing 33%. Win.

First Solar to Profit If Trump Slaps Tariffs on Panel Imports – “If there is a determination of injury, a modest type of remedy will not be harmful at all to the industry and I think it’ll survive and more jobs will be created,” FirstSolar CEO Mark Widmar said on a conference call. “Hopefully what it will do is enable more manufacturing in the U.S.” Two things about FirstSolar – first off, they manufacture their solar panels mostly in Ohio. Secondly, their product – thin film – is different from, and competes directly with, the product being talked about in this case. As such – FirstSolar will benefit greatly on projects built in the USA if the tariff is put in place. They’ll have significantly less downward pricing pressure as there really isn’t any utility scale solar panel production in the USA.

Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

Iowa utility offers high ‘green’ pricing without adding renewables – Three Beyond Solar options are available: 100 percent solar, a 50/50 split of solar and wind, and 25 percent solar with 75 percent wind. In each scenario, generation capacity is sold in increments of 1 kilowatt and is added to a customer’s existing bill. The cost per kilowatt is $13.61 for 100 percent solar, $6.70 for 50 percent solar and $3.24 for 25 percent solar. The green energy comes from two existing contracts – nothing new will get built…and that isn’t necessarily an issue – someone did build these two clean plants (one wind, the other solar) – but the pricing seems a bit out of whack. Stay conscious of the pricing and structure of green programs.

ITC report: 26 U.S. module makers closed in the past five years – 26 U.S. module manufacturers have closed their manufacturing facilities in the past five years, a period during which imports of modules and cells increased nearly five-fold. In addition, the majority of U.S. module companies reported operating losses over the same time period. U.S. demand for solar products increased for the four years between 2012 and 2016, Malaysian, Chinese and Korean modules captured a larger share of the U.S. market in contrast U.S. module manufacturers. In a few phone conversations I’ve had with people in the know, there isn’t really a question as to whether or not US module manufacturers have suffered at the hands of Chinese monetary policy supporting ‘below profit’ solar panel manufacturers. The question becomes, not ‘Are US panel manufacturers being hurt?’, but instead ‘What is in the best interests of the nation-state?’ And that question becomes absolutely the question to ask as we are looking at a blunt, national tool to defend industry. Would a few highly robotocized factories populated by engineers/machinists/specialists/etc benefit the energy security of the state? Absolutely…however, are there also other, more complex, paths that might benefit us more?
