It’s a Tie! The USITC Announces Its Section 201 Solar Trade Case Recommendations

— November 3, 2017

On October 31, 2017, the US International Trade Commission (USITC) announced the remedy recommendations that it will forward to President Trump. As we have discussed in previous blogs (here and here), this case has been shaping the future of the US solar industry. Impacts have been felt around the world since May 2017, when Suniva and SolarWorld asked the USITC to investigate.

What Did They Recommend?

The recommendations of each USITC commissioner can be found here. In summary, they recommended a system involving import quotas, import licenses, and a percentage-based ad valorem tariff of up to 35% in the first year of implementation. The commissioners rejected Suniva’s petition to set a minimum import price at $0.74/W; in percentage terms, this would be comparable to a 100% tariff. Like with Suniva’s petition, the tariff will be reduced each year and will drop to up to 32% in the fourth year of its implementation (the best case would set the tariff at 15%).

So, What Will Happen Next?

On one side, even when the highest tariffs are applied, module prices in the United States would regress to those seen about a year ago—when the industry installed 14.6 GW of capacity, doubling its previous installation record. Thus, the effects on the downstream of the solar industry should be minimal. It is unlikely that the protection given by the USITC will be enough to create a boom for solar manufacturing in the United States, but it should be enough to keep a profitable cottage industry focused on the local market with modest growth potential.

On the other side, the tariff and quota limits will stop future global price declines from being reflected in the US market. This will affect the competitiveness of solar and hence, its expansion into areas with lower irradiance.

With China hitting 50 GW of installed capacity this year (3 times the second largest market), India poised to take over the United States as the second largest market, and installations in the global sun belt (Latin America, Middle East, South East Asia, and Australia) soaring, global solar players are unlikely to be affected by the tariff. However, potential mirror tariffs might push out US companies with local manufacturing capacity, like First Solar, from the international markets.

Overall, the recommendations of the USITC commissioners favor the status quo, keeping the solar industry intact but slowing its growth.

 

Sunrun: The Large Solar Provider Dilemma

— September 19, 2017

On August 24, Sunrun—the last of the large independent US solar providers—announced an agreement with Comcast, a leading cable provider in the country. The two companies plan to launch a strategic partnership to offer Sunrun’s services to Comcast’s clients.

Sunrun was founded in 2007 and found success innovating new ways to finance residential solar installations such as solar leases and power purchase agreements (PPAs). It created the solar as a service (SOaaS) business model, which became the foundation for the growth of the sector between 2010 and 2015. Until 2014, it seemed that solar leases and PPAs—grouped as third-party ownership in California’s Interconnection Applications Data Set—were going to be the winning business model in the SOaaS industry. These leases allowed large players to both increase the market size and displace local installers.

Changing Solar Market

In 2015, the market share of solar leases and PPAs in California—which itself represents around 60% of the US market—plunged to under 50% from 75% in 2013. Data for 1H 2017 shows third-party ownership at close to 30%.

The collapse of third-party ownership has weakened large solar providers compared to local installers. Large solar providers relied on their access to cheaper capital backed by significant margins in their leases to run large business development teams and finance the installations. As residential solar customers moved into cash or loan buys, local installers became competitive again, reducing the profit margin per installation in the industry. This left large solar providers like Sunrun with high customer acquisition costs relative to profit per installation.

Under these circumstances, it is not surprising that Sunrun is looking for new and cheaper ways to attract customers. Even if this partnership with Comcast costs Sunrun its independent status, it may be worthwhile if the strategy is successful.

What Is in It for Comcast?

Comcast has shown interest in the energy sector in the past, and its Xfinity Home service includes a smart thermostat as one of the offerings. However, scaling it into a full-fledged energy solution would be costly, as Comcast would need to build a new team from the ground.

For Comcast, this partnership offers a relatively cheap entry into the solar and energy markets in which it can rely on its core skills (customer acquisition and management) without having to invest significantly in a new product. If successful, Comcast can push a more aggressive strategy into the energy sector either through Sunrun or with its own product.

Benefits and Potential

Customers of Comcast and Sunrun could also benefit from this partnership. The companies can put together a convincing solution for home automation by tapping on their offerings on the two main services around home automation—security and energy.

The success of this partnership will depend of Comcast’s ability to cross-sell energy services to its current customer base. Comcast operates in a market with limited competition and high barriers to entry, which is different from the solar market. The sales process of solar is also different from that of cable. Solar is a long-term investment (even leases and PPAs require long-term contracts). Therefore, customers take long before making a final decision and, in some cases, it will require home visits before the deal is closed. This means that Comcast cannot simply add solar to its bundles. It will have to invest in training its sales force if it wants to sell solar services effectively. It won’t be easy, but if Comcast succeeds, it may signal a new era for energy.

 

Can Solar Make an Impact on the Transportation Market? Part 2

— September 5, 2017

After a few conversations with Scott Shepard about PV systems in EVs, I began to come around to his view that solar is too expensive and the roof space too limited to make a solar-equipped EV work at the mass market scale. But then I read about another PV in transport project that made economic sense: Indian Railways’ newly launched solar diesel multiple unit (DEMU) trains. A total of 16 300W solar modules are installed on each coach on the train for ₹9 lakh ($13,950 or $2.9/W). The Indian Institute of Science estimates that the annual energy yield in a solar rail coach will be between 6,820 kWh and 7,452 kWh. This could displace 1,862 liters of diesel, saving around $1,650 per year at $0.88/liter diesel.

Lessons Learned

I see two key elements that make the project work. The first lesson from India is that solar in transport makes more sense when it is displacing liquid fuels rather than electrons. Going back to the Prius example from the first blog in this series, if the solar roof was available in Toyota’s non-plug-in version of the car, its economic effect would be significantly better. If a non-plug-in version of the Prius could run for 2,190 km per year on only solar, it could save about 150 liters per year, which would have a value of around $180 per year (using Japan’s gasoline price in July 2017). The investment in a solar roof could break even within the lifetime of the car, so the current cost of the add-on could be justified.

The second lesson is the use of off-the-shelf modules. In this way, the project benefits from the economies of scale that PV systems are famous for. It would be difficult to use off-the-shelf modules in cars, but if Toyota introduced the solar roof in all its Prius cars (for example), it could increase the production rate of solar roofs for the Prius from a couple of thousand per year to about 350,000 per year (global Prius sales in 2016). Modules with similar high efficiency cells in the wholesale market sell for about $0.50/W (i.e., $90 for the 180W used in the Prius).

Most of the costs arise from integrating the PV cells into the roof of the car. These costs could decline significantly due to economies of scale as well. If Toyota could cut costs to those of the train company ($540 for 180W already installed in the car, including inverters and other costs), the breakeven period would be about 2.5 years. Slashing costs would make a solar roof a no-brainer (especially for consumers like me who would be able to drive the car without ever using a charging point or stopping at a gas station).

Interesting Niche

This would open an interesting niche for solar companies. If all the EV and hybrid EV cars sold globally in 2017 (expected to be between 3 million and 4 million) had a 180W roof, an additional 840 MW (an extra 1%) could be added to global solar PV demand. But solar roofs need a champion to push them into the mass market in the same way Tesla pushed EVs away from the margins. My last blog discussed two startups that are exploring this niche. However, traditional manufacturers could do the same to differentiate their brand and cars from the competition. Toyota is an obvious choice given its brand association with hybrid cars, but other manufacturers could step in. For example, Volvo could be a great candidate since it is hybridizing all its models.

 

Can Solar Make an Impact on the Transportation Market? Part 1

— August 31, 2017

People have dreamed of solar-powered vehicles for decades. The first World Solar Challenge race occurred in 1987 and the first American Solar Challenge (then called Sunrayce) was held in 1990.

Thanks to improvements in solar costs and the EV value chain, the dream is closer to reality. Two startups (Sono Motors in Munich, Germany and Lightyear in Eindhoven, the Netherlands) have projects underway. Sono Motors successfully crowdfunded more than half a million dollars in September 2016 and revealed its first car on July 27, 2017: the Sion. According to Sono, the Sion will cost between $13,200 and $17,600 depending on the battery size and will run without refueling for around 30 km with a 1 kW solar system. It will be available in 2019.

Lightyear is an unofficial spinoff from Solar Team Eindhoven. This team built the Stella and Stella Lux solar racers—both winners of the Bridgestone World Solar Challenge Cruiser Class. The cruiser class replicates traditional cars, with seating space for four people. Lightyear has been taking preorders since June 29, 2017 for €119,000 ($138,000). The car is expected to offer a range between 400 km and 800 km and travel between 10,000 km and 20,000 km per year in low irradiation areas (e.g., United Kingdom and the Netherlands)—charging only with its PV system.

Today’s Solar-Powered Vehicle Option

A solar-powered vehicle option is available on the market today. Toyota’s latest Prius Prime Plug-in Hybrid offers an option in Japan to add a 180W solar roof that charges the main battery. Toyota claims that the roof will give the car a maximum solar rage of 6 km in Japan, which is a country with medium irradiance levels. The option to add the solar roof costs $2,500, which adds 5%-10% to the vehicle price. This seems expensive given the savings it provides compared to buying electricity from the grid that costs below $70 per year, even with the high electricity prices in Japan. From a convenience point of view, the system might make more sense for people without parking at home and short daily drives. My daily commute is around 4 km, which means that if I had the Prius Prime Plug-in Hybrid with the 180W solar roof add-on, I could drive mostly electric all year without visiting a charging point. It is still an expensive feature, however, which is why most mobility analysts—like my colleague Scott Shepard, who analyzes the EV market—have been skeptical about the idea of putting solar and EVs together. Yet, other automakers are exploring the PV-EV connection, as well. Audi has just announced it will unveil a prototype EV with solar panels on the roof to extend the vehicle range.

Despite the skepticism, one successful solar-powered vehicle project exists. Part 2 of this blog series will look into Indian Railways’ newly launched solar diesel multiple unit trains.
