Envision Solar to Showcase EV ARC™ 2020 and DC Fast Charging at FedFleet 2020 in Washington, D.C. - Yahoo Finance

SAN DIEGO, Jan. 29, 2020 (GLOBE NEWSWIRE) -- Envision Solar International, Inc., (Nasdaq: EVSI, EVSIW) (“Envision Solar,” or the “Company”), the leading producer of unique and sustainable infrastructure products for electric vehicle charging, energy security and outdoor media, today announced that the Company will introduce the new EV ARC™ 2020 and EV ARC™ DC Fast Charging to fleet management and procurement professionals at FedFleet in Washington, D.C. January 28-30, 2020.

FedFleet 2020 is a unique, one-stop educational experience that assembles fleet management and automotive procurement professionals in one place for three days of training. In 2018 over 90% of Envision’s revenues came from government sales and in the first three quarters 2019 almost two thirds also came from government, with many sales resulting from exposure to the Company’s products and sales personnel at government fleet trade shows.

Due to its unique design, Envision’s EV ARC™ 2020 will continue to operate in flood waters of up to 9 ½ feet deep It provides a source of electricity to charge vehicles and support other vital services during blackouts and other emergencies. It is transportable and rapidly deployed. EV ARC™ DC Fast Charging offers a 50kW charge which provides up to 1,100 miles per day, and like all EV ARC™ products requires no construction, electrical work or utility bill. The Company believes these attributes to be meaningful contributors to the continued strength in its government sales.

“Government fleets need rapidly deployed and highly scalable EV charging infrastructure solutions,” said Desmond Wheatley, Envision Solar’s CEO. “Our products get them the charging they need, from a renewable source that meets their carbon reduction goals. Our products also keep their vital fleet vehicles running during blackouts. All of this from a Made in America product. FedFleet is a great place for us to tell this story and demonstrate our products. We look forward to winning more business with government agencies and to enabling them to save taxpayer money on construction and utility bills and to drive on sunshine.”

Invented and manufactured in California, the patented EV ARC™ and EV ARC™ HP products fit inside single parking spaces without reducing available parking. The EV ARC™ product generates enough clean solar electricity to power up to 225 miles of EV driving in a day. EV ARC™ HP DC fast charging systems provide up to 1,100 miles per day. The EV ARC™ system’s solar electrical generation is enhanced by EnvisionTrak™ (patented) which causes the solar array to follow the sun, generating up to 25 percent more electricity than a fixed array. The energy is stored in the EV ARC™ product’s on-board energy storage for charging day or night, and to provide EV charging and emergency power during grid failure. The EV ARC™ product is a permanent solution that provides Level I, Level II and DC Fast Charging but because it requires no trenching, foundations or installation work of any kind, is deployed in minutes and can be moved to a new location with ease. EV ARC™ products are manufactured in the company’s San Diego facility by highly talented, mission-driven team members, including combat veterans, individuals with disabilities and other underserved demographics.

MIT and NREL see solar modules reaching well below 20¢ per watt - pv magazine USA

Although, the author of this article sees a path below 15¢ per watt. Researchers at MIT, working with financial modeling teams at NREL, have projected the electrical losses and financial gains of thinning solar cells from the current 160 micrometers to 50 micrometers.

January 29, 2020 John Weaver

Solar module innovation is alive and well.

We’ve seen an increase in efficiency of almost 50% from an industry standard 15%, to Longi recently setting a mono PERC record at 22.38%. Just last week, Trina took the “large wafer” concept from the lab to manufacturing line in less than a year. And heterojunction solar modules seek to redefine what is possible.

Researchers at the Massachusetts Institute of Technology and the U.S. Department of Energy’s National Renewable Energy Laboratory have published a paper describing the potential technical and financial outcomes of pushing the solar cell manufacturing industry to thin its solar wafers from today’s industry standard of 160 micrometers (μm) to 50 μm. The paper, Revisiting thin silicon for photovoltaics: a technoeconomic perspective, also gives guidance on the various technologies that’d need to advance to enable this reality.

The first step the researchers took was revisiting an old idea — how thin is too thin when it comes to cutting solar ingots into solar wafers? Generally speaking, thinning wafers reduces their ability to capture available photons, especially those photons in the near-infrared spectral range. We thought we’d found a sweet spot at 160 μm thick, however these scientists simulated the thicknesses in the above images across multiple modern and future solar wafer types and came to a conclusion that we can do better.

The researchers note when considering the case of “1 ms bulk lifetime,”  the efficiency of 50 μm versus 160 μm thicknesses are 101%, 98%, 97%, and 97% from left to right in the above image — using almost 69% less silicon.

In the above images, AL-BSF represent historically standard aluminum back screen wafers, PERC represents the current product’s we’re buying today, while advanced PERC represents products that we can buy at the cutting edge – like REC Group’s Alpha Product, or Trina and Jinko’s TOPcon products. “Adv HE-Tech” represents future heterojunction products, with advanced efficiencies and qualities designed to take advantage of “thin wafers.”

To give you a broader feel for the difference between the current and our cutting-edge future, the above table compares a standard mono PERC wafer at 160 μm versus the advanced heterojunction 50 μm product. Note that kerf loss (wasted silicon ingot between each wafer cut away) goes from 95 μm to 28 μm – which essentially means that almost two entire advanced solar wafers are lost making one modern wafer today.

More notably though, notice how module prices fall from 32¢/W to 20¢/W — a 37.5% fall. Note that it also drops the non-subsidized cost of electricity from these modules, on a power plant level, by 23% – a not trivial number at all. One important thing to note on that 32¢/W price for modern modules – the number is from 2018. We’re currently reaching 24-20¢/W for standard mono PERC modules that are greater than 19% efficiency.

This author speculates that we could adjust the value to consider modern mono PERC at the above mentioned 20 to 24¢/W – and adjust the advanced heterojunction 50 μm product down to a range of 15 to 12.5¢/W for modules.

The report authors looked across the entirety of the solar module manufacturing process and found multiple areas in the process where money could be saved. Looking at 2010 to 2018, the total capex for module production from raw silicon to module declined by 75% from $1.52 to $0.39/watt per year. The advanced heterojunction 50 μm wafers could potentially reduce manufacturing capex by 48% further.

A relationship was found where with every 10 μm thickness reduction, manufacturing capex declines roughly by 1.3¢/W/year, and module cost declines roughly by 0.6¢/W/year. The authors found that thin silicon, regardless of whether using existing, cutting edge, or developing cells can reduce cost of electricity by more than 5% relative to 160 μm wafers. To put it in perspective, the industry has transitioned to PERC to harness the 3% reduction in LCOE.

To gain the greatest benefits put forth in this paper, those of the advanced heterojunction solar cell, new solutions must be found in multiple areas as noted in the below chart. For instance, we need to learn how to cut thinner wafers. The current cut is a 255 μm cut, with 95 μm of that being wasted, whereas cutting edge described here is 78 μm — and 70% lesser silicon. Imagine how the silicon ingot manufacturers – feeling massive pricing pressures – might feel if their product suddenly generated three times more than its current value.
