Solar rebates are fleeting in many locations—now you see them, now you don’t. Case in point, Burbank Water and Power (as is the case with its cousin in Glendale) is notorious for offering, and then taking away solar rebates. We monitor BWP’s website for new developments, and we have now learned that they will be holding a lottery for possible rebate funds next July. No additional details were made available; presumably they will be posted sometime in June.
Given that development, we decided to update our overall rebate status. Here is how things stand generally in the Run on Sun service area as of this date:
|Utility||EPBB ($/Watt)||PBI (¢/kWh)|
|(Click to see website)||Residential||Commercial||Non-Profit||Residential||Commercial||Non-Profit|
|Anaheim||Unavailable until June, 2014||Unavailable until June, 2014|
|Azusa||Wait List||Wait List|
|Burbank (BWP)||Lottery in July, 2014||Lottery in July, 2014 (30 kW or less)|
|Glendale (GWP)||Unavailable until 7/1/2014||Unavailable until 7/1/2014|
|Los Angeles (LADWP)||$0.40||$0.70||$1.45||Not used|
|SoCal Edison (SCE)||$0.20||$0.25||$0.90||2.5¢||3.2¢||11.4¢|
Here are a couple of very important qualifications to what appears in that table:
This is a moving target; watch this space.
We have been teasing out bits and pieces of our new book, Commercial Solar: Step-by-Step, all summer as we neared the end of the publication process. Well today we can formally announce that it is available both at the Run on Sun Publishing eStore (where we get a better royalty - hint, hint!) and on Amazon.com!
Commercial Solar is intended for two primary audiences:
As the title suggests, the book provides an overview of the process by which an interested party - say, a facilities manager - can go from knowing next to nothing about commercial solar to identifying appropriate contractors to provide bids, analyzing those bids to make meaningful comparisons, determining financing options that are appropriate and even overseeing the actual installation process.
The book features a Foreword written by Boaz Soifer, VP of Sales at Focused Energy:
The material could be dry (much of the reading on this subject is), but is instead casual but precise, clearly laid out, and made accessible through handy use of a narrative in which the Facilities Manager of a fictional company undertakes a commercial solar project himself…
In his typical style—approachable, honest, quirky, and occasionally scathing—Jim has thoughtfully flattened out the complex world of commercial solar PV into an understandable roadmap that anyone can follow to project success.
Interested? You can download a two-chapter excerpt of the book for free, here. Better yet, you can purchase the book today from either our eStore or Amazon for just $9.95. If you are interested in bulk sales (i.e., ten or more copies), discounts are available. Please contact us at Bulk Sales for more information.
And of course, we welcome your comments either here on the blog or at Amazon. Thanks for your support.
Pasadena Water & Power (PWP) has just made their long anticipated rebate reduction announcement. Effective October 16, 2013, residential rebates for solar power systems will plunge from today’s $1.40/Watt to just 85¢/Watt - a 40% reduction. Other rebate rates were not changed.
This means that for a typical residential system installation of a 6 kW system - say 20 LG 300 modules with Enphase Energy M250 microinverters - your rebate will decline by more than $3,000! That is a lot of money to leave on the table so the time to act is NOW!
Once the rebate is reserved, homeowners have a full year to install the system - so even if you aren’t ready to go forward with a project for another six to nine months, you still want to get your rebate reserved now to take advantage of rates that we will never see again.
Please keep in mind that PWP has also moved over to PowerClerk - an online tool that your solar contractor must use to submit your rebate application. Your contractor has to be pre-approved by PWP to access PowerClerk. You will want to make sure that your contractor is familiar with PowerClerk so that there aren’t any problems with your rebate application that could cause it to be rejected, forcing you to have it resubmitted at the lower rates.
Run on Sun is already approved on PowerClerk with PWP so you can be confident that your rebate will be processed properly the first time.

In Part One of this three-part Case Study we learned how Westridge School chose Run on Sun as their solar contractor. Here in Part Two we focus on the actual process of the installation as seen from the client’s perspective.
With the paperwork filed and the rebate secured, Run on Sun had a very tight window — less than two weeks in April 2012 — in which to install and connect all 209 solar modules and get the monitoring software up and running. The goal was for the project to be completed and operational by the time Westridge students returned from Spring break, so time was of the essence.
For the rooftop display Run on Sun used a microinverter system supplied by Enphase Energy, which allows customers and solar installers to track the output of the modules, individually or collectively, from the convenience of their computers, iPads or smartphones. This software was a selling point for the school, because it would make the technology accessible to students and allow teachers to creatively incorporate aspects of the solar system’s performance into classroom instruction.
The modules were grouped into three sub-arrays that formed a larger circuit. Under each module, a microinverter was installed to convert DC energy gathered from the module into AC power, which could be combined and fed back into the school’s electrical service. The 1:1 ratio of microinverters to modules allows for a more detailed readout that lets users know the output of each module and gives an easy-to-read display should anything ever go amiss, from a connection issue to dirt on the module’s surface.
Throughout the installation Williams remained on hand to oversee the work, though there were no delays and no change orders requesting funds beyond what had been originally estimated. Within the assigned two-week period, Run on Sun had completed the project on time, and everything was in working order.
“I’ve worked with a lot of contractors, and I can honestly say, in this situation, this was one of the most seamless projects we’ve ever completed,” Williams recalls. “They were here early on the first day and, boom, they got it. It was done on schedule, at the price they said and signed off by the city. I wouldn’t hesitate to do a project like that again.”
April 2013 marked the one-year anniversary of Westridge School’s solar installation, and Williams reports the system is running smoothly. The Enphase software makes it easy for officials, teachers and students to monitor the activity of all 209 modules, but Run on Sun also keeps a close eye on the operations and reaches out if and when an anomaly is detected. In the event that an outage or a decline in energy production should occur, the company promptly notifies the school.
For example, when one of the modules stopped reporting and apparently needed to be replaced, Run on Sun immediately contacted Williams to schedule a visit. The rest of the modules were still in full working order, and upon close inspection it was revealed that a connection had come loose. Still, to ensure maximum performance, the company replaced the microinverter at no cost to the school.
Another time Williams received a notification email from Run on Sun after the campus Internet connection had been temporarily cut during some service upgrades. And when the energy dipped from its norm of exceeding system predictions to 98 percent of anticipated, a call came in with a recommendation to check the array for accumulated dirt. After a brief spray with a hose, the system was back to producing at maximum capacity.
At the one-year mark, the school became eligible to receive its first annual rebate from Pasadena Water and Power. This is the first of five annual rebates it will receive, the dollar amounts directly correlated to the system’s actual production.
When a technician came from the city to assess the energy output of the system, the school was excited to learn the results. The city’s readings gave some very welcome news, indeed — the energy generated by the installation was above and beyond the original estimate provided to PWP, and it looked like the first rebate would be larger than anticipated.
“He said, ‘You’re over your estimate,’ and that’s all we could ask for,” says a thoroughly pleased Williams. “To date, everything that was promised to us was delivered — plus.”
In terms of the amount of energy generated, the rooftop system has continued to outpace expectations. The school expected to see a return on its investment in seven years, but it’s shaping up to come in as few as six. Because of the installation, Westridge is using 30 percent fewer kilowatt hours and is seeing its bills reduced by thousands of dollars each month, in addition to the rebate. The overall savings is far greater than the cost of running the air-conditioner in the gym, the initial impetus for bringing solar to campus. To Williams, making the decision to go solar was a “no-brainer.”
“The neat thing about this is it runs itself. If somebody walks onto campus, they don’t know we have a 52 kilowatt solar system on campus,” he adds. “They don’t see it. It doesn’t impact anything. All you do is save money.”
We will conclude this three-part Case Study with Part Three - Advice for the Solar Reluctant.
The preceding is an excerpt from Jim Jenal’s upcoming book, Commercial Solar: Step-by-Step, due out this summer.
Today we begin a three-part series offering a Case Study of the Westridge project, one year later. Part One reviews the process that Westridge used to choose the solar contractor to build its solar project. Part Two details the actual construction and the experience of the School in managing the project. Part Three concludes with some advice to the Solar Reluctant on why solar really does make sense.
For the past 100 years, Pasadena’s Westridge School for Girls has prided itself on providing a top-notch education that grooms young women into the leaders of tomorrow.
As part of a legacy of bringing cutting-edge ideas and innovation to campus and making it all come alive in the classrooms, school officials have made it a goal to pursue and complete at least one project related to sustainability on campus each year.
In late 2011, looking forward to the next year, they decided to address a perennial request made by parents and students over the years: that an air-conditioning system be installed in the school gymnasium to keep crowds cool on hot days. While the school could likely raise funds from the parent community to purchase and install a system, the financial and environmental impact of running it and creating a new drain on the power supply were less than sustainable, says Brian Williams, Westridge’s Director of Facilities.
So, to offset the cost and energy consumption of the desired air-conditioning unit, officials decided to fundraise for another project at the same time, one that would mitigate the cost and consumption of the A/C.
They asked parents and students if they’d be willing to raise money to install a solar system on school grounds.
Solar energy was not exactly new to the school. In 2009, Westridge had installed a small system on its newly built LEED-Certified Platinum science and math building. There some of the panels were placed near the ground, where students could see them up close and interact with the technology.
For the new project, however, school officials were thinking much bigger. They wanted to maximize energy savings by installing a large-scale system that would provide a solid and swift return on their investment and take advantage of a local rebate being offered by Pasadena Water and Power (PWP) that was set to decrease drastically after the end of the year.
Ideally, the new installation would generate enough energy to cover the usage from the A/C in the gym and still supply additional power to other buildings on the campus, saving on the school’s overall monthly electric bill. At the outset, there were no specific parameters for the project, Williams said, just a location.
“We found our biggest roof and said, ‘Fill it up,’ he says.
The south-facing slope of the roof of the Fran Norris Scoble Performing Arts Center would be the perfect place to set up a large installation. With an area of approximately 4,000 square feet, it received direct sunlight throughout most of the day and was elevated enough to tidily keep the operation out of sight.
Williams turned to three different solar companies, seeking estimates to help define the scope of the project and determine a total cost that would guide the school’s fundraising efforts.
The first two companies Williams considered were those the school had worked with on past projects. One was a large, international solar provider that had worked on the 2009 science building installation. The other had previously worked with Westridge on nearby residential properties.
Run on Sun, the third provider approached regarding the installation, was the only one the school had not personally worked with before. The Pasadena-based company had contacted school officials earlier that year and delivered a presentation on its installation process, qualifications and services provided. That presentation was fairly comprehensive, and made enough of an impact for Westridge to include Run on Sun in the bidding process.
“We didn’t have any actual experience with them, but they had very good references that we checked as we went through the bidding process,” Williams explains.
Finding the right contractor for the job was a thorough search that employed analysis and research. But beyond that, Williams, who’s worked in the facilities department for more than two decades, relied on his own gut instinct and experience to determine which company could best get the project done in a short amount of time and leave no detail unchecked.
Since Westridge is a privately funded nonprofit, it is not under the same obligation as public entities to accept the lowest contractor bid. Cost, however, was still a primary consideration in selecting an installer.
“I have a fiduciary responsibility in my job to make sure the projects we do here are cost-effective and help maintain our campus in a positive way,” Williams says. “I can’t do anything that doesn’t make fiscal sense.”
The cost estimates provided by the three companies for an approximately 50 kW system were not that disparate from one another, coming in at about $4.25 per watt. One thing Westridge did have to be cautious about in its review of the estimates, however, was the possibility of a provider initially underbidding the project with the intention of requesting additional funds through change orders after a contract had been signed. The contractor who was truly right for the job would be one who provided an accurate estimate up front and diligently held true to that figure.
When considering the PWP rebate, Williams knew the school stood to save about half the total cost of the installation over the course of five years. Additionally, all three bidders told Westridge officials they could expect to see a full return on their investment in about seven years. Overall, the project made great financial sense.
Since the cost estimates that came in from the three bidders were relatively similar, Williams also analyzed each company’s references, experience and credentials. For example, he did consider installers certified by the North American Board of Certified Energy Practitioners (NABCEP) to have an advantage over uncertified companies. Another important factor was the presence of a licensed electrician on the staff. “It’s an electrical installation, and I wouldn’t let anybody who wasn’t a licensed electrician be on site,” he says. “I’m guessing the city wouldn’t allow it either.”
Throughout the selection process, Westridge officials knew they were working under a bit of a time crunch. If they missed the window to apply for the PWP rebate, the project would end up costing significantly more than the amount they had raised. Because of this, hiring an installer who could successfully submit all the paperwork before the fast-approaching deadline, and one they could trust to get the application process 100 percent right the first time, was of critical importance.
In this regard, Run on Sun was a standout, Williams says. They promised to take care of all the paperwork, filing within the deadline period and eliminating the extra bureaucratic steps the school would otherwise have had to take.
“They managed the whole process — I basically [just] had to sign the form,” he says.
The fact that Run on Sun had a strong working relationship with the city of Pasadena was another important consideration that worked in its favor, given Westridge’s own solid standing in the community. The attention to detail and professional accountability demonstrated by the company throughout the bidding process brought the local provider to the top of the list, making the ultimate decision to go with Run on Sun an easy one, Williams says.
“It was a combination of the cost, return on investment, their relationship with the city, the impression we had with the provider, how they presented the information and their references. We looked at all of it.”
