What Is ‘Solar-as-a-Service’?

Editor’s Take: UrbanVolt says it is focusing its light-as-a-service model on solar, and the idea is intriguing. The company believes the service, which basically puts UrbanVolt in charge of project managing a solar installation, will do away with the current practice of locking companies into a 25-year lease for on-site solar. Instead, a monthly service fee structure will allow the company to own the solar installation after seven years.
So, what’s the next ‘as-a-service’ model UrbanVolt will produce? According to the company’s website, energy storage-as-as-service will be available soon.

Podcast: Local Solar Power: Red Plus Blue Makes a Green Tea Party

In this episode of Building Local Power, we interview Debbie Dooley, President of Conservatives for Energy Freedom and co-founder of the Green Tea Coalition in the southern U.S. Dooley’s organizations promote “consumer choice in the energy field” to “provide competition” and stop monopolies from limiting their customers’ options in renewable energy. The Green Tea Coalition features a collaboration between members of the Tea Party Movement and progressives in the Green Party and the Democratic Party in Georgia and other southern states.

Full transcript is available here.

This conversation tracks closely with a previous Building Local Power episode where our experts discussed hyper-partisanship in our political system. That episode, Breaking Through Partisanship: Left-Right-Local, discussed how local issues and local politics cuts across partisan barriers and brings coalitions of concerned residents together.

“I live in Atlanta, there’s different roads that will take you to your final destination of Atlanta. The roads you take is dependent upon where you’re coming from,” says Debbie Dooley of talking to people across the political spectrum in order to promote local renewable energy. “As long as we work together, someone’s willing to work together to advance clean energy and solar and other renewables, I don’t care why they’re advancing it, wanting to work to advance it. I just care in the end result.”

Here are some great reading and watching recommendations from our guest, Debbie Dooley:

Can Puerto Rico Really Depend on Microgrids and Renewables for Power?

As Puerto Rico sets out to rebuild its electric system knocked out by Hurricane Maria in September, can it become a model for renewable energy?

Scores of government agencies, think tanks and energy experts are mulling that question, as much of the U.S. Caribbean territory still lacks electricity.

This week, the Puerto Rico Energy Resiliency Working Group, created under the New York governor’s office, released a 63-page plan for the island to “Build Back Better” over a decade at a cost of $17.6 billion. Among its recommendations: $1 billion in microgrids for critical infrastructure and rural communities.

Experts say the challenge is not technical. Costs have dropped so much for solar, wind and other technologies that renewables can be cost-effective. The big issue instead is political and financial: Is there the concerted will and independent supervision required, and where’s the money for it?

Before the storm, debt-burdened Puerto Rico had relied mainly on a government utility that runs big fuel-fired power plants to supply electricity to its 3.4 million residents.

Puerto Rico set targets for renewables years back that it has failed to reach. Its recovery from Maria has not been well-coordinated between federal and local government agencies, community groups, businesses and others. Those factors don’t bode well for making the island a model quickly, experts say.

“The problem is systemwide in scale, and you’re dealing with essentially a bankrupt government and bankrupt power company,” Matthew Perks, founder of New Energy Events (NEE), said. NEE organizes the annual Caribbean Renewable Energy Forum.

Four months after the storm, with no centralized plan to guide rebuilding, it’s been “battlefield triage,” he said, adding that “they’re [still] just trying to get the lights on.”

Rocky Mountain Institute (RMI), an independent nonprofit, is working with groups in Puerto Rico on a long-term plan for cleaner, cheaper energy. Part of the effort: microgrids, similar to the solar panel and battery back-up system that Tesla installed to power the Children’s Hospital in San Juan after the hurricane. Microgrids could serve a home, neighborhood or large facility like a hospital or factory. They could operate on their own and also be linked to the larger grid and sell excess energy to the grid operator, the government’s Puerto Rico Electric Power Authority (PREPA).

“That would require a new involvement from PREPA on what facilities would get paid for their sales to the grid,” Roy Torbert, principal with RMI’s Islands Energy Project, said.

For rural communities, PREPA could install solar panels and battery storage on buildings themselves — even without immediate links to the broader grid, suggested Jorge Camacho with the U.S. government’s Smart Grid program. In Puerto Rico’s mountains, there’s little population density, most homes use relatively little power, and stringing transmission lines is very expensive. PREPA could place small solar and batteries on rural homes and businesses through the “own-operate-maintain” model similar to what Green Mountain Power has in Vermont. The systems likely would cost $7,000 to $10,000 per rural home, a sum that could be financed with federal recovery funds and federal subsidies for solar, Camacho said.

“Of course, the process would have to be transparent and have oversight from the independent Puerto Rico Energy Commission,” added Camacho, a Puerto Rican engineer who formerly served as infrastructure lead at the Public Service Commission of Washington, D.C.

Insufficient oversight has been a major component behind PREPA’s current woes. The island set up its independent regulatory group only three years ago, and rules and procedures still need strengthening for the commission to function effectively, said former PREPA engineer Tomas Torres Placa, executive director of the nonprofit Institute of Competitiveness and Sustainable Economy known as ISCE-PR.

“We have faith that with a strengthened energy commission, we can comply with the renewable portfolio standard,” Torres said, referring to plans to reach 20 percent renewables by 2035. Yet strengthening would require staffing by competent technocrats, not political hacks, he added.

Puerto Rico Gov. Ricardo Rossello is requesting roughly $17 billion in federal funds to revive the island’s energy sector, which now uses renewables for less than 3 percent of electricity generation. Many observers will be watching how new contracts are handled. PREPA in late October cancelled a $300 million repair contract with tiny Whitefish Energy Holdings of Montana after public outcry over terms that included paying $319 an hour for a journeyman lineman.

Rossello has sought help in rebuilding from New York. The working group that just released its report includes representatives of the New York Power Authority, PREPA, Puerto Rico Energy Commission, U.S. Department of Energy, Navigant Consulting and others. Its proposals build on New York’s experience after Superstorm Sandy five years ago and PREPA’s recent efforts.

Yet funding remains an open question, as does long-term will and proper oversight.

“Puerto Rico has an opportunity now to have a more reliable, resilient and cost-effective grid,” said Torbert. “There are many sources of private capital. What they need is certainty their investment will be repaid. That all speaks to having a strong and independent regulator in place.”

Eight Great Women in the Business and Science of Solar

It has been a long, long, long road for the global photovoltaic industry and its participants from its early days with few manufacturers and support primarily limited to oil companies looking for a feel-good business unit to what seemed like its overnight success in the mid-2000s. In 1977 the industry had 1.74 MWp of capacity to produce PV cells. At the end of 2017 the industry had 98 GWp of capacity to manufacture PV cells.

The men and women responsible for the PV industry growth from its beginnings as an oil company hobby to the fastest growing source of electricity in the world often gather at scientific conferences and drink to their old, pioneering days. Working in the PV industry in the 1970s, 1980s and 1990s required more than hope, it required a deep and steadfast belief that the industry would prevail, would become mainstream and would set the tone for the future of electricity generation — because … there was a time when the solar struggle was over whether it would survive as an industry at all.

It is easier to believe in the future of solar today than it was decades ago. This article honors eight of the women who believed and persevered and pioneered the PV industry of today and without who it might be a very different industry indeed.

Each woman has in her own way championed the cause of climate change as well as the cause of the solar industry and has worked tirelessly educating, conducting research and deploying solar technologies to ensure the future of the industry.

This article honors the contributions of women in science and business and whose careers stand as an example to young women around the world of what is possible.

Izumi Kaizuka, RTS, Japan

Dr. Izumi Kaizuka has dedicated her life to the study of the global photovoltaic industry its technologies, business models and deployment. Dr. Kaizuka majored in Chemistry at Tokyo Metropolitan University. After graduation, she joined Lion Corp. as a researcher working in R&D for specialty chemicals for surface modification of polymers and electro conductive materials. In 2003, she joined RTS Corp., PV specialized consultancy in Tokyo established in 1983

Since 2003, Dr. Kaizuka has served as the Japanese representative to IEA PVPS Task 1, an international working group for “Strategic PV Analysis & Outreach.” She is one of the authors of Task 1’s key annual report “Trends in Photovoltaic Applications” and provides analysis of global PV industry as well as Japanese PV market trends. Dr. Kaizuka also contributes to global corroboration on PV standards as the duty chair of the national committee of IEC TC82.

The bare facts of a person’s resume do not describe the dedication, the quiet passion, the commitment and joy that that person brings to their work. In solar, work is most often a calling. Dr. Kaizuka is committed to promoting women in business and research and serves as the chair of WinPVJ, Division of Women in Photovoltaics, JSPS 175th Committee on Innovative Photovoltaic Power Generating Systems and PVTTMT, a business women’s network.

The PVSEC Special Award, along with the Cherry Award and the Becquerel Prize, is one of the distinguished scientific awards in the global PV industry. Over the many years that these awards have been presented there have been few women recipients. The PVSEC Special Award is presented to honor a PV professional’s outstanding contributions for technology development and the promotion of photovoltaic solar energy conversion. The decision is made by the PVSEC organizing committee. In 2017 Dr. Kaizuka was awarded the PVSEC Special Award at the PVSEC-27 held in Otsu, Japan for her tireless commitment to the science and application of photovoltaic technologies.

People who work with Dr. Kaizuka describe her as dedicated, of course, and as knowledgeable, patient, willing to sacrifice her time for her industry and friends and a true mentor to young women and men entering the industry.

Renate Egan, UNSW, Australia

Basic research is a creative discipline relying as much on inspiration and ideas as on data, repeatability and experimentation. People who can marry the creative with the technical while focused on the best use of data are rare, and they are crucial to the solar industry.

Currently an Associate Professor at the University of New South Wales, Australia, Dr. Renate Egan leads UNSW’s activity in one of the last remaining bastions of pure research in the solar industry, the Australian Centre for Advanced Photovoltaics (ACAP). In her role, Dr. Egan manages ACAP’s projects and coordinates activities with ACAP’s funding agent the Australian Renewable Energy Agency (ARENA). Her administrative activities include balancing the needs of ARENA with the requirements of ongoing research.

During her career, Dr. Egan has served as managing director of R&D at Suntech Australia as well as CTO and managing director at CSG Solar AG. Her focus is on manufacturing costs, new technology development and the development, management and use of data for better analysis and decision making.

Those who have worked with Dr. Egan say that she has been a passionate and untiring supporter and promoter of solar energy, especially photovoltaics, for decades. Dr. Egan consistently pushes the boundaries of photovoltaic research and the use of better — not just more — data. Dr. Egan is a Co-Founder and Chair at Solar Analytics, a start-up providing software for predicting energy generation from solar energy systems as well as a Partner at Solinno, another Australia-based start-up company that consults in project management, risk assessment, policy and process documentation, IP development and management and project funding.

Dr. Egan’s commitment to the science, engineering and to the analytics required to keep the global PV industry on its trajectory to becoming a mainstream electricity source serves as an example to young women considering a career in the solar industry.

Darlene McCalmont, McCalmont Engineering, U.S.

Of her career, Darlene McCalmont says, “I always say I left the dark side of chemical manufacturing for the bright side of solar even though I feel my operations experience in the chemical industry has played well into why I have been successful in the solar industry. Being part of the solar industry growth has definitely left me feeling good every day about what I do and the contribution to the environment I have made.”

Darlene McCalmont graduated from Ohio State, one of the few women in the late 1970s to earn a degree in Chemical Engineering. Following graduation, she went to work for Celanese Corp., a chemical processing company based in Texas. While in Texas she earned her MBA. She married her childhood sweetheart Tom and they moved to California where Darlene worked for Safety-Kleen, a chemical cleanup company.

Solar installation pioneers often say that they started their business out of their garages and with a truck. After the chemical company was sold and subsequently downsized, Darlene, together with her husband Tom, founded Regrid Power, a solar installation company in the Bay Area. They now run a thriving solar engineering firm, McCalmont Engineering.

People who work with Darlene describe her as detail oriented, operationally excellent, exacting but fair, organized, insightful and thoughtful. One of Darlene’s favorite expressions is “In God we trust. All others bring data,” which pretty well sums up her approach to operations and execution. Her common-sense approach is true to her no-nonsense, Midwest sensibility, farm girl origins.

Common sense and a well-grounded world view is not the whole story; instinct and knowing when to act on it is crucial to business and in life. Back to Darlene’s days working for the California chemical cleanup company; one day a particularly noxious chemical came in to the facility on a truck from somewhere up north. Darlene knew that the chemical was highly dangerous. In the middle of the night her sixth sense kicked in and believing that there was something not-quite-right about this particular truck she went to the facility at 1am to process it through. She was right. The chemical was in the incorrect type of truck to contain it, and it was gradually etching its way through the bottom of the truck.

Terry Jester, Silicor Materials, Iceland

In the global solar industry, all roads eventually wind back to ARCO Solar, one of the U.S. pioneers of photovoltaic manufacturing. ARCO was formed in 1977 after Atlantic Richfield acquired Solar Technology International, a company founded by PV industry pioneer Bill Yerkes.

ARCO was the first PV manufacturing company to produce 1 MWp of modules in one year. This may seem small by today’s standards, but this achievement helped put the PV industry on the road to today’s massive scale and lower costs.

Terry Jester, a pioneer in PV manufacturing, began her solar career in 1979 at ARCO Solar as a mechanical engineer working on solar module design and reliability. She has spent 38 years working on producing and refining the cost and performance of solar cells and modules. Her early work focused on creating a product that could be warranted for 25 years, which was accomplished in the late 1980s.

Terry remained with ARCO through several name and ownership changes, from ARCO’s acquisition by Siemens, to Shell and finally to SolarWorld. She served as a director at SunPower. In June 2008, she joined Hudson Clean Energy as their Entrepreneur in Residence. Terry joined Calisolar in 2011 as their Senior VP of Operations and stayed with the company through its name change to Silicor Materials, leading the company as its CEO and now Chairman.

People who work with Terry Jester describe her as focused on manufacturing excellence and as unfailingly kind, supportive and a wonderful mentor to young women seeking an engineering career.

Dr. Sarah Kurtz joined NREL in 1985 as a post-doc and now teaches at the University of California Merced. She has the honor of being the first woman to win the PV industry’s prestigious Cherry Award.

The Cherry Award was established in 1980 and is named for William R. Cherry, a PV industry Pioneer. It is presented annually at the IEEE PVSC in the U.S. During her acceptance speech at the 2012 conference Dr. Kurtz said: “Persistence in the face of skepticism should be our response when the world says it cannot be done.” This sentence sums up her career and her philosophy.

Dr. Stuart Wenham, CTO, Suntech, and the winner of the 37th Cherry Award presented Dr. Kurtz with the 38th Cherry Award at the 2012 conference. Presenting the award, Dr. Wenham said, “Sarah has worked tirelessly for 20 years. Dr. Kurtz’s body of work has helped the acceleration of growing high-quality cells and measuring multi-junction cells. More recently, she has looked at reliability issues of integrating multi-junction cells and solar PV in general into larger systems.”

Generosity sums up the career of a woman who has dedicated her life to solar research, committed her time to promoting the science of the industry through her steadfast focus on scientific excellence. People who know her note her dedication, focus and willingness to mentor others.

Christiana Honsberg, Arizona State University, U.S.

Tesla Opens New York Store for Solar, Cars and Storage

If there’s any doubt Tesla Inc. isn’t just a car company anymore, its brand-new Manhattan showroom should put it to bed. On Friday, Tesla opens a store in New York’s Meatpacking District that, for the first time, will sell cars, solar panels and batteries permanently under one roof.

In a sparse, glass-walled space, the Model X sport utility vehicle and Model S sedan are on display alongside solar offerings and Powerwall storage systems. A Model S sits across from a sign that reads: “Produce Your Own Clean Energy.” In this store and others that Tesla’s enhancing across the U.S. starting Friday, car and energy salesmen will work side-by-side.

Tesla’s Chief Executive Officer Elon Musk took a big gamble buying SolarCity Corp. last year. It opened up the billionaire to harsh criticism from some investors who described his takeover of the solar company—led at that time by his cousin, Lyndon Rive—as a bailout rife with conflicts of interest. The synergies of solar and electric vehicles weren’t immediately clear, and Tesla has been working to integrate the businesses ever since, positioning itself as an energy—not strictly a car—company. This new New York store is the physical manifestation of that.

Besides an occasional pop-up, solar was rarely before available in Tesla stores. Now, potential solar customers can discuss the power products with energy-focused salespeople in person—before or after checking out a new SUV. If they like the pitch, a site surveyor will then be sent to their homes to finalize the plan, followed by installation. Employing energy consultants directly in stores on a permanent basis lets the company cross-sell products and puts it on the offense at a time when residential solar is slumping in the U.S. after 16 straight years of growth.

Although solar panels and the Powerwall home battery system are on display, noticeably missing from the expanded offerings in the 10,900-square-foot (1,013-square-meter) showroom is the Model 3, Tesla’s more affordable and much-hyped electric sedan that began production in July. Output of the car, which starts at $35,000 before options, has been plagued by production bottlenecks, though the first non-employee customers just began getting their cars, suggesting progress on the production front.

The long-anticipated Tesla solar roof is also not on display at the new Manhattan location, which replaces Tesla’s smaller storefront in Chelsea. They’re expected to be sold in stores in 2018 after testing is completed on those installed on employees’ houses.

Next year, Tesla customers will also be able to begin taking delivery of their electric cars at the Meatpacking location, rather than going to the Brooklyn store to pick up their new rides. The Manhattan store won’t offer a service center like the Red Hook showroom near Brooklyn’s industrial waterfront does—but it does have a free espresso bar for Tesla customers.

The opening of the new Manhattan store coincides with an important company event: the completed integration of SolarCity into Tesla. In the year since Tesla paid $2 billion to buy SolarCity, it’s ditched its door-to-door sales model, and next week, the integration is expected to be complete. With the exception of a website, the SolarCity name will mostly vanish, with all solar products instead sold under the Tesla brand.

Though the synergies of solar and electric vehicles weren’t immediately obvious, the deal proved prescient: Other solar installers seeking to reduce high marketing costs amid market contraction have since sought partnerships with better-known brands. Tesla has also refocused the solar unit’s strategy. SolarCity, which popularized the no-money-down lease, chased growth at all costs and amassed more than $3 billion in debt along the way. Tesla’s energy unit has had success with solar-panel sales and appears more focused on profitability.

The new store may be in the heart of one of Manhattan’s toniest sales corridors, but it’s not intended just for downtown residents. The area draws tourists and commuters, and the store is situated beneath the heavily trafficked High Line elevated park.

Expansive floor-to-ceiling glass faces out at The Standard hotel, allowing for sun to pour into the mostly white interior. The new store is on the same block as a Diane von Furstenberg showroom and is just a few blocks from an Apple Inc. store, which sports a similar clean, crisp design.

The rented space includes several mounted touch-screens where buyers can configure their Model S and Model X vehicles, which are available for delivery to customers in the next month or two. Drivers can also put down $1,000 reservations for the Model 3, much like they do online. But with a wait list of some half a million customers, most buyers placing an order this week won’t get their Model 3s until next Christmas—or later.

For any holiday shoppers who can’t wait a year or more for their Model 3s, solar panels—which could be installed within the month, permits and snowfall willing—may be the way to go. There’s an energy consultant on-site.
