SunPower announced the development of a new line of solar panels that it will market under the Performance Series product name.  The new products utilize a proprietary manufacturing process to assemble conventional silicon solar cells into panels with increased efficiency and reliability compared with conventional panels.  Designed to target a new set of customer segments and global markets, the Performance Series panels will be available in all three of SunPower’s segments – residential, commercial and power plants – later next year.

“Our new line of Performance Series products continue the SunPower tradition of higher efficiency, superior reliability and enhanced aesthetics compared with conventional panels, all in a lower priced product configuration,” said Tom Werner, president and CEO of SunPower.  “Together with our best-in-class E-Series and X-Series back-contact panels, we are expanding our product line to offer customers a wider range of product choice and increase our reach to additional markets, further enhancing company growth.”

The Performance Series product line is an outgrowth of technology developed by Fremont, CA-based Cogenra Solar, which SunPower acquired earlier this year.  Over the space of several years, Cogenra developed and extensively tested a novel cell interconnect technology which eliminates the need for the soldering and copper ribbons that are a major cause of power loss and degradation in conventional panels.

“SunPower’s new Performance Series is a powerful combination of Cogenra’s innovative cell interconnect technology, with more than 30 patents issued and pending, together with our extensive solar panel intellectual property, manufacturing experience and scale,” Werner said. “These new products will provide our customers with up to 15 percent more power than conventional panels with improved reliability and shade tolerance.”

floridians-for-solar-choiceThe grassroots coalition of Floridians for Solar Choice, comprising over 65 diverse organizations and thousands of Floridian supporters, is strong and advancing in their effort to remove and limit barriers to solar power that currently exist in the Sunshine State. The initiative’s vast network of petitioners across the state is steadily gaining momentum as the remaining needed petitions are collected, even in the face of high-dollar opposition from monopoly utilities and their supporters.

“We continue to aggressively move to secure the required signatures, and we call on all Florida citizens who believe in Solar Choice and clean energy to join our effort.” said Dr. Stephen Smith, Executive Director, Southern Alliance for Clean Energy and founding member of Floridians for Solar Choice. “It is clear that FPL and the other utility monopolies with their proxy groups are having to spend a significant amount of money to recruit people in order to intentionally mislead voters about their “dumb” petition which does nothing to advance solar in the Sunshine State.”

It is evident that the Solar Choice initiative would upset the monopoly utilities’ status quo: the utility-sponsored amendment received hefty campaign donations totaling more than $2.3 million in October.

Following a positive ruling from the Florida Supreme Court in October, the Solar Choice campaign’s total number of verified signatures continues to grow with more than 207,000 already verified by Florida’s Division of Elections and another 200,000 signed and awaiting verification. The ballot proposal – designed to expand solar choice by removing barriers that limit solar ownership models – continues to gain wide support as more than 65 businesses, associations, conservative groups, faith communities, clean energy and environmental organizations now comprise this diverse coalition.

Buyers will pay a premium for solar homes, appraisers find

Photovoltaics added value to homes in six markets, according to a new report titled “Appraising into the Sun: Six-State Solar Home Paired-Sales Analysis,” led by a researcher from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and a home appraisal expert. Researchers engaged a team of seven appraisers from across the six states to determine the value that solar photovoltaic (PV) systems added to single-family homes using the industry-standard paired-sales valuation technique, which compares recent sales of comparable homes to estimate the premium buyers would pay for PV.

The appraised premiums also confirmed statistical modeling results from a large Berkeley Lab study conducted in 2013, which found that buyers were willing to pay $15,000 more for a home with the average-size solar photovoltaic system (3.6 kilowatts), or about four additional dollars per watt of solar power, though premiums for any individual home are market dependent and are likely smaller given currently falling installed solar prices.

“These results will benefit appraisers, real estate agents, and mortgage lenders who increasingly encounter PV homes and need to understand the factors that contribute to, and detract from, market value,” says study co-author Ben Hoen, a researcher in the Energy Technologies Area of Berkeley Lab. The soaring growth in U.S. home PV systems—which totaled more than half a million homes in 2014—highlights the need for additional valuation options.

For each of the 43 pairs of comparable PV and non-PV homes, appraisers found premiums were highly dependent on the underlying system and market characteristics. These include the size of the system, the available incentives and installed prices at the time of sale, and the underlying retail electricity rates. The appraisers therefore recommend not using a one-size-fits all approach, but rather one that considers these factors. They found both the replacement cost, specifically one that takes into account federal state and utility incentives, and the present value of energy savings are likely good predictors of premiums found in individual markets.

“Many appraisers and lenders prefer the paired-sales valuation techniques that are standard in the real estate community, but comparable pairs of PV and non-PV homes are not always available, which can result in PV systems on some homes receiving no appraised value,” says lead author Sandra Adomatis, an appraiser who helped develop the Appraisal Institute’s Green Addendum and who has written and spoken extensively on valuing green features. “One of the most important contributions of our study is to show that paired-sales analysis accords with cost, income, and statistical-modeling approaches to estimating PV home premiums. Lending appraisal guidelines and expectations should allow these methods for estimating PV home premiums when comparable sales are not available.”

The study also found that price per watt was the appropriate metric for valuing PV systems and that there was no consistent difference in days on the market between PV and non-PV homes.

The study concludes with a list of recommendations for improving PV home valuation.

The research was supported by funding from the U.S. Department of Energy SunShot Initiative. The SunShot Initiative is a collaborative national effort that aggressively drives innovation to make solar energy fully cost-competitive with traditional energy sources before the end of the decade. Through SunShot, DOE supports efforts by private companies, universities, and national laboratories to drive down the cost of solar electricity to $0.06 per kilowatt-hour.

How solar contractors can survive in a post-incentive, highly competitive market

The Federal Investment Tax Credit (ITC) is set to expire at the end of 2016 – and if it does, many residential solar installers might face trouble. Shayle Kann, Senior VP of GTM Research, referred to the expiration of the Investment Tax Credit as “the cliff” which will force the solar industry back to its 2014 installation levels, even though only growth is predicted from here on out.

This article is contributed by Pamela Cargill, principal at Chaolysti, a strategic consulting firm that helps residential solar installers operate more efficiently.

This article is contributed by Pamela Cargill, principal at Chaolysti, a strategic consulting firm that helps residential solar installers operate more efficiently.

On top of this, many local solar rebates are declining or sunsetting altogether, leaving the ITC as one of the last remaining solar incentives. Net energy metering (NEM)–another kind of incentive–is also under fire in many utility jurisdictions as witnessed in a number of high-profile battles since 2011.

Installers need to watch carefully how NEM 2.0 cases and utility rate cases are shaping up in the utility territories where they operate. Changes to NEM, proposals for fixed charges and minimum bills, and rate cases threaten the customer savings models we have depended upon until now. In most areas, NEM offers retail rate compensation for any solar electricity sold back to the grid.

Many proposals to change NEM will result in solar customers being offered wholesale rate or lower compensation for the solar they sell back to the grid. Aside from being more complicated to model project financials, this will impact customer savings significantly. Rate cases will also challenge customer savings. Proposals including residential demand charges, time-of-use rates, fixed charges and minimum bills will all have impacts on modeling customer savings and are being explored in some combination depending on your jurisdiction.

What Can Be Done?

For residential installers, the complex threats via NEM 2.0 and utility rate changes compound on top of the potential loss of the ITC into a powerfully uncertain environment. Find out from your state SEIA chapter on how you can get involved being a face for the solar industry in local campaigns that target key members of Congress who can support the extension of the ITC or by participating in conversations at NEM and rate cases.

Installers who successfully close the gap of 30% of project cost for direct ownership or 20% for third-party ownership may gain advantage over their peers who are playing the “wait and see” game. That’s almost $5,000 per project that installers need to reduce. However, this “gap” is likely more like 40-50% when overhead “all-in” is factored. That’s a lot of ground to cover.

Installers need to understand where they play the strongest in the project fulfillment cycle. Is it sales, design, installation, customer experience? Small, pure play solar installers who do everything from lead generation to long-term customer support may not find themselves in an advantageous position given the trend toward increasing costs of customer acquisition, as seen with the Q3 2015 earnings announcements from SolarCity about rising customer acquisition costs.

The residential market is gravitating toward an ecosystem model, where sophisticated marketing and sales organizations deliver lower cost-of-acquisition customers to an array of service providers connected together via software platforms and strategic partnerships. The entire solar value chain from manufacturing to distribution to installation to the end customer will begin to operate in a more integrated and interoperable fashion as the industry continues to mature. How will you fit in to that structure?

Solar installers need to look at how organizational design, business process and software tools or platforms can help them compete given the changes that are coming. The first place many installers will need to start is freeing up the time of the business owner to allow them more freedom to work on the business as opposed to in the business. That means delegating responsibility to other staff members and putting guidelines and policies in place for everything from sales margins to design standards to project or customer escalations. This important step alone will pave the way for the real strategic thinking needed to chart the course.

Software will continue to play a key role in streamlining and automating increasingly complex processes. Software tools already help streamline the proposal process and will continue to as the financial modeling becomes more complex. Many sales and proposal platforms are already starting to add more complex modeling that accounts for different sell-back compensation for NEM 2.0, demand charges, and more. Ask your proposal tool provider how they are accounting for these changes in their development roadmap. If they aren’t, you might want to consider how strong of a partner they will be to your business.

Most importantly start preparing now. No matter what changes–whether the ITC, NEM, rate cases, the rise of storage, the smart home, electric vehicle adoption–where solar falls in the solution landscape is sure to change. Get ready.

The FPL Solar Pavilion and FPL Solar Patio, both of which are canopy-like structures that will offer shade for race fans, and FPL Solar Park collectively consist of more than 7,000 solar panels generating 2.1 MW of zero-emissions energy. The three solar structures will be located in the Midway, Sprint FANZONE and Lot 10 parking area. The total weight of the structures (900 tons) represents the equivalent of more than 500 NASCAR stock cars.

“We’re thrilled to see the new solar structures taking shape,” said Daytona International Speedway President Joie Chitwood III. “These areas represent our commitment to providing a better fan experience as well as leveraging innovative ways to modernize our venue.”

The clean energy generated by the installation will prevent the emission of an estimated 2,200 metric tons of carbon dioxide each year – equivalent to an average vehicle driving more than 2 million laps around DIS. Once connected to the FPL grid, the solar energy at DIS will help to power approximately 400 Florida homes per year.

“As an avid race fan myself, it’s an honor to be part of the extraordinary redevelopment of one of Florida’s most iconic sites and tourist destinations,” said Eric Silagy, president and CEO of Florida Power & Light Company. “The thousands of solar panels we’re installing here will provide zero-emissions electricity for our customers and the Speedway’s operations, helping power races that are viewed around the world. Importantly, our efforts here at Daytona are yet another example of our ongoing commitment to expanding cost-effective solar here in Florida for the benefit of our customers, both large and small.”

Upon completion of the installation in January 2016, DIS will become one of the top five U.S. professional sports venues in terms of solar energy capacity. The FPL Solar Circuit at Daytona International Speedway is one of several FPL solar projects that will add 225 MW of new, zero-emission solar energy by the end of 2016, cost-effectively tripling FPL’s solar capacity and making Florida one of America’s top solar energy producing states.

What are solar meters?

Solar meters allow for the display of real-time PV energy production data. Photo: Solar-Log.

Solar meters can refer to pyranometers, which are used to measure solar radiation flux density (W/m2), or devices used to measure the kWh production from a PV system. This article is about the latter.

Solar meters collect PV yield production and local energy consumption to monitor and analyze PV plant performance. Solar meters often come with a monitoring function to alert plant owners of issues with PV plant performance, letting them quickly resolve issues and maximize return on investment. Plant data is transferred to a monitoring platform that provides a concise presentation of PV yields, monetary savings and plant performance.

“Solar meters record electricity readings using integrated current transformers (CTs),” said Anne Nelson, marketing manager at Solar-Log. “Solar Meters can be cellular enabled, which allows for a dependable communication from the plant to the monitoring platform, where the installer and customer can view performance remotely via the web.”

To measure electrical power (kW)—the rate of production—two aspects are measured: current and voltage, according to John Browne, applications engineer at Continental Control Systems. The current represents the amount of electricity (electrons) flowing through a conductor. Voltage represents the pressure pushing the electricity through the conductor. Current is typically measured by sensing the strength of the magnetic field produced when electricity flows through a conductor. A current sensor installed around a conductor is the current transformer (CT). The voltage is measured directly by the meter via two or more connections to the electrical service. The meter multiplies the current by the voltage to calculate apparent power (VA), and compares the current and voltage signals to calculate power factor (Pf). The apparent power is multiplied by the power factor to calculated real power (P). Real power is integrated over time to calculate real energy (kWh).

Meters, which do the measuring, can be internal or external to the inverter. All inverters include an internal meter, but frequently these meters are not revenue grade. External meters can be installed along the AC line between the inverter and the main distribution panel. This allows one meter to measure output from multiple inverters, which can create significant cost savings, as well as a collection of more precise PV yield data if the meter is “revenue grade.” Some solar meters can connect directly to the inverter through an RS485 or Ethernet cable, providing additional data for plant monitoring and diagnostics, Nelson said.

A revenue grade meter meets the ±2% reporting accuracy requirement in accordance with the American National Standards Institute (ANSI). Most meters embedded in solar inverters do not meet the ANSI certification requirements which means that these readings are much less accurate. In the U.S. PV market, many solar financing or incentive programs require revenue grade metering precision.

“In order to reduce field installation labor, the industry is heading towards integrating the meter into the inverter at the factory,” said Browne.

Even aside from the financing and incentive programs that require revenue grade metering, more and more, solar meters are becoming a necessary component of solar PV plants, Nelson said. Meters allow PV plant owners to monitor their plants and ensure the plant is performing correctly. Meters also provide the production information that is necessary for plant owners to calculate a solar PV plant’s return on investment.

WGL, a diversified energy company, has expanded its distributed generation capacity, which consists primarily of photovoltaic solar, to 150 MW DC installed or under construction across the United States. The company announced plans today to invest $200 million in fiscal year 2016 in solar and other distributed systems, representing a 50% increase in renewable power generation.

“At WGL, we know that the future of energy requires the integration of renewable resources, such as solar, into our energy ecosystems and infrastructures,” said Sanjiv Mahan, president of WGL Energy. “We will increase our solar investment this year, demonstrating our commitment to providing clean energy answers to communities, businesses and governments across the U.S.”

To date, WGL has invested over $500 million in distributed generation systems in 16 states and the District of Columbia. The company’s $200 million distributed generation investment plan in fiscal year 2016 represents a 26% increase from the previous year.

WGL solar projects in service generated 147,000 MWh of power this year and include a system developed for Indianapolis Power and Light Company. Through this system, WGL provides power to various organizations within the state, the largest of which is the Indiana Airport Authority.

WGL solar systems under construction include a 4.2 MW DC ground-mounted, single-axis tracking system in Palmdale, Ca., which will produce more than 4,900 MWh of energy per year, enough to power about 600 average-sized households and eliminate roughly 3,000 tons of carbon dioxide emissions annually. In addition, also under construction is a 2.2. MW DC ground-mount system that will power a large company’s manufacturing facility in Hagerstown, MD. Supplying clean and renewable energy to the 1.5 million square foot space, the project will yield 2,665 MWh of energy annually, providing an energy solution to a major business in the region.

A brighter picture emerges amid uncertainty, according to Mortenson solar industry study

At the top of Mortenson Construction’s corporate headquarters in Minneapolis sit three solar arrays, generating enough energy to offset 40,000 driving-miles of carbon emissions annually. On the floors below, solar production is tracked and displayed in everyday terms for our team members to see, such as laptops-in-operation or miles-driven.

mortenson-constructionSolar installations are among a host of measures we have employed since 2009 to increase sustainable practices on our campus. We do this to not only walk the walk, but to express optimism for the solar industry as the alternative energy poised to outpace all others, as it has reached cost parity with coal and natural gas.

And we’re not alone in predicting a bright future for the solar industry.

Recently, Mortenson released the findings from our 2015 Solar Industry Study, a research effort aimed at taking the pulse of the industry. Feedback gathered from over 200 attendees at the Solar Power International (SPI) conference, representing utilities, developers, independent power producers (IPPs), financiers and suppliers, indicated that most industry professionals anticipate a robust future for solar.

Considering that the Federal Investment Tax Credit (ITC) is slated to be reduced from 30% to 10% for commercial properties, this is not an insignificant finding. While most of the conference attendees we spoke to say the 2016 ITC reduction will have an immediate impact on solar activity, 57% of utilities, developers and IPP professionals still believe the long term outlook of solar will still be strong.

Respondents mentioned several factors that would counteract an ITC reduction in the long run, including better financing solutions, falling costs and continued innovation in energy storage. Industry cost reduction is driving much of the optimism regarding future trends. The price of utility-scale solar has fallen by more than 70% since 2008, according to the Lawrence Berkeley National Laboratory.

Respondents strongly believe that electricity storage, including the massive battery plant being built by Tesla Motors Inc. in Nevada, will be a significant game-changer. Other infrastructure developments lending solar a potential boost include distributed generation, net metering and smart-grid technology.

Lastly, there’s a feeling that the current ITC will be extended, in the same manner as the Production Tax Credit for wind projects has been extended in the past.

What was true in previous years should ring true for solar developers attempting to secure a power purchase agreement: Due diligence is key, according to utility professionals.

There continues to be a palpable optimism around solar energy, it is already at grid parity in many markets. Even a glut of natural gas available at low prices is not seen as a significant threat to renewable energy. Two-thirds of utility, developer and IPP respondents believe solar electricity has or will achieve the same megawatt-hour costs within the next five years.

Of course, the lynchpin to any growing industry is the people behind it. According to our findings, solar is attracting a wide influx of professionals. Of those we surveyed, one-third have worked in renewables for three years or less. Meanwhile, industry participants with 10 years or more under their belts have worked–on average–at at least two firms, indicating a fluid renewables workforce presented with an abundance of opportunity.

What forces will shape the industry in a year or five years from now? At this point, we can only guess. But if the passion and commitment felt across the industry are any indication, a more secure and sustainable energy future is close at hand.

This article is contributed by Trent Mostaert, the Vice President and General Manager of Mortenson Solar and Emerging Renewables Operating Group.  Trent has helped grow Mortenson into the largest full service EPC provider in the nation.  He is driven by a desire to continuously eliminate waste from processes and develop innovative ways to consistently deliver far superior results to customers.
