How will commercial solar be affected by tariffs?

The following post is by Kyle Pennell, Content Manager at PowerScout.

This week, the Trump administration slapped tariffs on imported solar panels and solar cells. Set to start at 30 percent, the tariffs will decline each year by five percent and expire after four years.

Commercial and residential rooftop solar installations emerged relatively unscathed from the tariff ruling. Compared to utility-scale solar installations, rooftop installations have higher “soft costs” – the costs associated with customer acquisition, marketing, supply chain costs, installation labor, and so on. Soft costs account for nearly two-thirds of the overall commercial solar installation price tag. Of the remaining hard costs (those associated with equipment), the panels themselves only comprise about 10 to 15 percent of the overall installed system price.

In other words, for a typical commercial solar installation, the total cost will increase only about three or four percent. A standard system costs around $20,000; a three percent increase, then, would add just $600 to the price tag.

Overall, however, many analysts believe that the tariffs won’t have a significant effect. Fatih Birol, executive director of the International Energy Agency, said, “The global solar industry will adjust. The penetration of solar in the U.S. will continue.”

MJ Shiao, head of GTM Research’s Americas division, said the tariff decision “has a meaningful but not destructive impact on solar installations.”

And for at least some in the solar industry, the tariffs actually spell good news. While they comprise a small minority (about 15 percent) of jobs in the solar industry overall, domestic panel manufacturers broadly stand to gain from the tariffs. Companies that produce novel solar products could also benefit.

Tesla, for instance, will begin nationwide installations of its solar roof this year. Unlike traditional solar panels, the solar roof is composed of roofing tiles that look like any other but contain solar cells to generate electricity. Tesla imports the solar cells used in the tiles, but the tariff on solar cells won’t go into effect unless 2.5 gigawatts’ worth of cells are imported. Since only 0.5 gigawatts of cells were imported last year, the tariff on cells is unlikely to limit production. Tesla has also announced their plans to use imported solar cells to produce traditional solar panels.

Like other U.S. panel manufacturers, First Solar also stands to benefit from the tariffs. The company produces thin-film panels made with cadmium telluride and doesn’t even require imported solar cells. First Solar has announced plans to expand its existing manufacturing capacity in Ohio, and its share price climbed nine percent in after-hours trading following the tariff announcement. Ohio Senator Sherrod Brown (D) said the trade decision was “welcome news” and suggested that tariffs will “help level the playing field” for American panel makers.

Even some installers, who were broadly united against any kind of tariff, have benefited (at least temporarily) from the tariff announcement. Share prices for Sunrun and Vivint Solar, for instance, were bolstered by relieved investors who had expected even steeper tariffs.

Jigar Shah, the founder of SunEdison, said the tariffs were “exactly what the solar industry asked for behind closed doors” and characterized them as “good news” overall.

Still, over 80 percent of U.S. solar installations utilize foreign panels, and the tariffs will hurt some segments of the industry, especially solar installers. Abigail Harper, president of the Solar Energy Industries Association, said the tariffs will “create a crisis in a part of our economy that has been thriving, which will ultimately cost tens of thousands of hard-working, blue-collar Americans their jobs.” The SEIA estimates that 23,000 jobs could be lost this year alone – though that figure is considerably lower than last year’s estimate from Bloomberg New Energy Finance and Clearview Energy Partners, which projected that tariffs could cause the U.S. solar industry to shed 88,000 jobs this year.

As prices rise, previously anticipated installation rates are expected to slow. While the tariffs are in effect, total installations will decline about 10 percent relative to the level that was previously projected. But utility-scale solar, not commercial and residential solar, will suffer the most. Prices for utility-scale installations could jump by 10 percent, and 65 percent of the overall decline in installations will be due to the slowdown of utility-scale projects.

The tariffs stem from a trade complaint brought by solar panel manufacturers Suniva and SolarWorld. The companies filed a petition with the U.S. International Trade Commission last year, blaming foreign competition for crippling domestic solar panel manufacturing. Together, they argued in favor of severe tariffs on imported solar panels.

The petition and the ITC’s subsequent ruling were broadly opposed by solar installers, as well as free trade advocates and developers of solar power plants. A bipartisan group of 69 members of Congress sent the ITC a letter urging the commission to oppose tariffs.

The tariffs were primarily aimed at panel makers in China and other Asian nations. Trump regularly vilified China and its trade policies during the 2016 presidential campaign.

But China’s Jinko Solar, one of the world’s largest panel producers, said the tariff decision was “better than expected” and even suggested that it might build a manufacturing plant in the U.S. And despite the fact that it’s owned by Shunfeng International Clean Energy Ltd., a Chinese company, Suniva thanked the president for “holding China and its proxies accountable.”

China and South Korea have criticized the White House’s decision and may petition the tariffs before the World Trade Organization. Under pressure from the WTO, the administration might withdraw the tariffs.

China might also retaliate with tariffs of its own. And since China is America’s number one trading partner, Chinese tariffs could badly damage the U.S. economy.

Is San Diego America’s finest city?

San Diego calls itself “America’s Finest City.” That’s quite a claim. Yet somehow it seems to fly juuust under the radar. San Diego’s sun, zoo, Navy, chicken, and iconic hotel are known by many, but what about the city?

San Diego’s streets can seem very Seattle-like except the tree species.

I visited recently for a closer look. The verdict: Go there. San Diego is impressive from a tourist and urbanist city-loving perspective.

The Gaslamp Quarter might be the best downtown restaurant district on the West Coast. Picture a mix of historic and new, with eight blocks of restaurants and bars along Fifth Avenue overflowing to other streets. It feels like the real core of Downtown. The all-ages crowd mixes locals and visitors. Nightclubs and restaurants boom bass out their open windows (consider this when choosing a hotel), interspersed with quieter places and takeout of many cuisines. The open windows lend a summer resort feel even in the winter. Try Sushi Lounge on Market and get the salmon poke.

San Diego’s corporate presence is relatively small, a standard local worry. It’s also not concentrated Downtown. The real office core is 10 miles north in La Jolla, with the country’s #3 biotech cluster (some say), techs like Qualcomm (unless it’s taken over!), and UC San Diego. This means Downtown can focus more on housing, tourism, and nightlife. This is an interesting contrast to Seattle’s huge office CBD which pushes other uses to its fringes. It’s nice from a tourist perspective, but probably not so nice if you want to walk or ride transit to the office. Downtown San Diego has been adding quite a bit of housing, probably for the lifestyle more than to serve the Downtown workforce.

This ravine has a semi-wooded trail at the bottom.

New residential towers on the Downtown fringe.

San Diego overall is denser than you might think, sort of like central LA or Seattle – lots of bungalows, plus a surprising amount of multifamily. There’s lots of infill, with that great West Coast trait of trying to use land as efficiently as possible (because it’s expensive). Vacant lots are rare, aside from parking lots around the Downtown fringes that have been going away quickly. Steep hillsides and ravines woven throughout the city provide a mix of built and natural areas.

Retail in centralized neighborhoods tends to be in familiar walkable corridors like University Avenue (sort of like our 45th, with stretches of activity) or small walkable nodes. The most visible difference might be the palm trees. It’s worth a long walk.

San Diego’s low transit usage is therefore surprising. Just 3.9% of in-city residents used transit for commutes per the Census Department 2012-2016 survey, and just 3.1% walked. That’s despite the weather and some rail transit. Seattle (albeit with a smaller city limit) was 20.8% and 10.1%. The gap has apparently been getting wider since then as San Diego’s mode splits have worsened and Seattle’s have gotten better. One reason: our jobs and big university are centralized.

Another reason is very high parking requirements for new buildings. With some exceptions, even studios require 1.25 parking spaces per unit, and a two-bedroom requires two spaces! That’s a huge cost to renters. It’s also encouragement for people to have cars and use them, versus Seattle where parking is often separate. As a result, San Diego’s infill seems to be about large sites that can fit parking and fewer but larger units. The Seattle resident who pays $1,000 for a micro would probably need a roommate in San Diego. San Diego’s home prices are similar to Seattle’s despite the lack of a corporate job base, and despite an apparently-mellower form of California empowered nimbyism.

Why is the job base lacking? Airline service is one obvious factor. San Diego International has a single, short runway hemmed in by North San Diego Bay. It’s very close in, with the glide path spectacularly (if noisily) a half-mile north of Downtown. Passenger counts are less than half of Sea-Tac’s. Tijuana Airport allows you to walk over the border to routes mostly within Mexico, but its numbers aren’t huge. A long-term solution isn’t imminent. Some hope it involves an existing military airport at Miramar or Camp Pendleton.

A ferry to Coronado Island is a nice trip. The terminal is Downtown next to the USS Midway aircraft carrier. It’s a slow boat but a quick ride. The view is fantastic. You end up near a business district with several restaurants (try Saiko Sushi). From there it’s a 25-minute walk to Hotel del Coronado on the ocean side with its beach and great architecture. When you get back to Downtown, tour the Midway.

Museums at Balboa Park

Balboa Park is an easy walk from Downtown. This is theoretically 1,000 acres with a mix of park and amenities. It’s sliced apart by a freeway chasm and much of it is a golf course and the Naval Medical Center. Some parts aren’t well-connected to the city. But it has beautiful areas and many of San Diego’s top museums as well as its famous zoo. It’s easy to spend a day there. If you get your fill of arts, culture, science, and aircraft, try the Model Railroad Museum, because cities and towns are cool in miniature.

Is this America’s finest city? A lot of cities have valid claims, and San Diego is one of them.

Kitchens that make your mouth water

Did you see that story on invisible kitchens? Here are just a few more photos to drool over.

Recently in the DJC: What’s cool in kitchens? Invisibility

“There’s a different story being played out by some kitchen designers today: kitchens that merge seamlessly into the rest of the main living space.

“Sometimes that’s because there are space limitations — a smallish apartment, for example, where the kitchen is cheek-to-jowl with every other room. Or there may be plenty of space, but no walls, so each living zone looks into the next.”

Henrybuilt, a Seattle designer and maker of kitchen furniture and storage systems, offers solid-surface counters with drainage for the sink. Storage cubbies for tools, napkins and bread are built into milled wood counters, which are then extended to create eating tables. Knife blocks, utensils, spices, pantry items, and recycle and trash receptacles all fit neatly out of sight in drawers and sliding cupboards.”

“Pay attention to how you illuminate the kitchen, says Sheva Knopfler, creative director of Brooklyn, New York-based

“’A statement light allows you to add a bold dash of your personality. It becomes the ‘artwork’ of the space,’ Knopfler says. Consider a large chandelier or a grouping of pendant fixtures.”

Olympics features the ‘Darkest Building on Earth’

Architect Asif Khan has unveiled a pavilion at the Pyeongchang Winter Olympic Games in South Korea, described as the “darkest building on earth.”



Located inside Olympic Park, the temporary structure measures 10-meter-high (32.8 feet). Asif Khan spray-painted the structure with Vantablack VBx2, a substance that absorbs over 99 percent of light.  Vantablack VBx2 is a sprayable version of Vantablack pigment, which British artist Anish Kapoor controversially acquired exclusive rights for in 2016. 

Because of the super-black spray-paint coating the pavilion, it is nearly impossible for the human eye to make out the contours of the building.  Rods tipped with tiny white lights protrude from the “super-black” parabolic curves of all four sides of the pavilion, giving the impression of stars suspended against the darkness of space.

In a statement, Khan described his vision, “From a distance, the structure has the appearance of a window looking into the depths of outer space. As you approach it, this impression grows to fill your entire field of view. So on entering the building, it feels as though you are being absorbed into a cloud of blackness.”

Inside the pavilion is a new dimension. A large white room clad in Corian creates an immersive water installation, in which 25,000 water droplets are released every minute and travel along carved channels until reaching a central pool.

The 35-meter by 35-meter building was commissioned by Hyundai Motor as part of its global art initiative, with the pavilion’s space theme aligning with the car manufacturer’s latest technology: a Hydrogen Fuel Cell vehicle.

The “stars” on the outside represent the chemical element on a cosmic level – gaseous balls shining due to the thermonuclear fusion of hydrogen into helium at their core.

Inside the pavilion, the liquid embodies hydrogen at a more human scale, as two atoms of a hydrogen bond with one oxygen atom to form water.

A fresh look at $2B plan to update Smithsonian

Architecture firm BIG – presented a revised proposal for the Smithsonian Campus Master Plan in Washington, DC. The vision was first unveiled in 2014 and has since been redeveloped following years of public comment and close collaboration with the Smithsonian Institution.

The new proposal reflects the team’s commitment to preserving the intimate character of the treasured Haupt Garden, while addressing existing and future needs, at one of the most historically significant areas and cultural institutions in the nation’s capital.

BIG’s $2 billion proposal – which involves lifting up two corners of the Enid A Haupt Garden and create entrances to an underground concourse connecting the campus’ museums – was revised following years of public consultation.

Members of the Commission of Fine Arts (CFA), local decision makers, residents and garden enthusiasts listened intently when Bjarke Ingels and representatives of the Smithsonian Institution gave a detailed account of the revised plans for the $2 billion restoration and revitalization of the South Mall Campus.

“Since our last proposal, we’ve been listening very closely to the public,” said BIG founder Bjarke Ingels.  “We wanted the general feeling and fondness for the Haupt Garden to remain the same while also increasing its enjoyment and use, offering educational elements and after hour programs.” 

The firm’s masterplan involves upgrading facilities, access and links across the Smithsonian’s South Mall campus, which includes a collection of museums that run along the southern side of the National Mall and front Independence Avenue.

These include the historic Smithsonian Castle, the Arthur M Sackler Gallery and the National Museum of African Art – all arranged around the Haupt Garden and joined by a concourse buried beneath.

BIG’s plans include an expanded visitor centre and new education space, which will be accessible from the Mall via descending walkways, and the reconfiguration of the entrance pavilions to the African Art Museum and the Sackler Gallery.

Ingels continues about the garden, “we also want to make more accessible some of the hidden treasures underneath the Haupt Garden – the National Museum of African Art and the Sackler Gallery – which are so well hidden that they’re under-enjoyed compared to the value they represent. If we can make them more accessible, more people might be tempted to explore.”

New visuals demonstrate the team’s intention to preserve the peaceful nature of the Haupt Garden and its diverse landscape, while also serving the wider needs of DC and the growing Southwest Ecodistrict community.

The revised proposal received a number of reactions following the presentation, and while some of the previous concerns have been addressed, the general sentiment remains that there is more work to be done. Pascal D. Pittman, AIA, Director of Quality Assurance at the engineering firm Setty & Associates later commented: “I got the impression that BIG finds itself between conflicting interests which remain to be reconciled. I thought the presentation, based on the parameters that BIG described, provided for a very elegant solution.”

Another reaction came from Robert Young, AIA, Associate Principal at Grimshaw and long-time DC resident and architect, who submitted a public comment: “[the Smithsonian’s founding donor] James Smithson’s call for ‘an establishment for the increase and diffusion of knowledge among men’ is noble and grand, yet, like our beloved Mall, has not been able to fulfill its goals as it – and the population it serves – continually grows and changes.

As the great facilities of the Smithsonian have fallen into disrepair or reach the end of their expected lives, and the great possibilities of the ‘Mall to Museum’ connection have frayed, it is the visionary response by the Smithsonian leadership and BIG that will allow a continued dialogue between our fundamental rights as citizens and our aspirations as humans. The work of BIG is bold, expressive, and often radically new: yet those characteristics are supported by thoughtful research, sympathetic engagement and conceptual synthesis.”

BIG’s new Master Plan seeks to improve existing facilities by proposing an expanded Visitor Center and new Education Space, accessible via descending entryways oriented towards the Mall; create clear connections, access points and visibility between the museums and gardens by reconfiguring the entrance pavilions to the African Art Museum and the Sackler Gallery; and to replace aging building mechanical systems that have reached the end of their lifespan, including structural reinforcements of the Castle to withstand potential seismic activity.

The first stage of the plan, the renovation of the Castle, is expected to begin in 2021.

About Smithsonian Institution
Since its founding in 1846, the Smithsonian Institution has been committed to inspiring generations through knowledge and discovery. The Smithsonian is the world’s largest museum and research complex, consisting of 19 museums and galleries, the National Zoological Park and nine research facilities.

About BIG-Bjarke Ingels Group
BIG is a Copenhagen, New York and London based group of architects, designers, urbanists, landscape professionals, interior and product designers, researchers and inventors. The office is currently involved in a large number of projects throughout Europe, North America, Asia and the Middle East. BIG’s architecture emerges out of a careful analysis of how contemporary life constantly evolves and changes. A pragmatic utopian architecture that steers clear of the petrifying pragmatism of boring boxes and the naïve utopian ideas of digital formalism. Like a form of programmatic alchemy, we create architecture by mixing conventional ingredients such as living, leisure, working, parking and shopping. By hitting the fertile overlap between pragmatic and utopia, we once again find the freedom to change the surface of our planet, to better fit contemporary life forms.
