A little over three years ago (my how time flies), we installed a 52kW solar project at the Westridge School for Girls, here in Pasadena. At the time, the project got a fair amount of attention (including an award from the City), was featured in a video (watch it here), and was the lead story in Enphase Energy’s Summer 2012 Newsletter.
Three years down the road, the folks at Enphase decided to circle back and check-in to see how the Westridge project had performed over the years - both in terms of saving money for the school, as well as being incorporated into the curriculum (another key goal of the project).
The article, titled — Solar on the Roof, Power in the Classroom — details how the Westridge Solar system has outperformed the modeled performance, producing 105% of the expected yield. That overproduction actually benefits the school twice: most obviously by lowering the bills that much more, but secondarily, by providing a larger than expected performance-based rebate payment.
Beyond that, however, the system has also proved to be an effective teaching tool, allowing Westridge students to analyze the copious amounts of data provided by the Enphase microinverters through the Enlighten, cloud-based data reporting service. One science class, for example, was able to discover how analyzing that data could detect the occurrence of a partial solar eclipse.
We are very proud of our partnership with Westridge and we look forward to doing another project with them in the near future.
Likewise, we are grateful for partners like Enphase Energy who are as committed to producing long term solutions as we are. That is one powerful pairing!
Pasadena Water & Power (PWP) is about to slash its rebates by as much as 55% effective May 1 - the first rebate reduction in three years. Here are the details…
We have said it before and we will say it again, our hometown utility gets the highest marks for running the best, hands down, rebate program around. Their folks are responsive, they have offered a consistent program since we got into this business, and their rebates have been among the highest offered in our service area. The present rebate rates: $0.85/Watt for residential and small commercial, $1.60/Watt for small non-profit systems have been at that level since 2012 - even while system prices dropped by 25%. (For large systems > 30 kW, the commercial rebate was 12.9¢/kWh of actual production paid over five years, while the non-profit version was 24.2¢/kWh.)
But all good things must end, including these great rebates - and they will, come May 1.
The new rates are significantly less generous - $0.45/Watt for residential and small commercial, $0.90/Watt for small non-profit. For larger systems the change is even more dramatic, with the rebate payout now only covering two years of production (instead of five) at the rate of 14.4¢/kWh for commercial and 28.8¢/kWh for non-profit. (One bit of good news, the threshold for systems to be paid rebates over two years instead of at commissioning is going up from 30 kW to 100 kW.)
So what do these rebate reductions really mean? Let’s look at a few examples.
A typical residential project of 5 kW (AC) that submitted a rebate application before May 1 would secure a rebate worth $4,250 (as opposed to na da in SCE territory). That same system will only receive a rebate of $2,250 - leaving an even $2,000 on the table. Ouch!
A 50 kW non-profit project would earn, over the next five years, a rebate worth approximately $92,400. But after May 1, only two years of payments will be made worth just $44,600 - a 52% reduction, leaving $47,850 blowin’ in the wind. Double ouch! The one side benefit, since this project is smaller than 100 kW (even though it is over the old, 30 kW threshold) it could qualify for the up-front rebate of approximately $39,200 at the time the system is commissioned - less money overall, but you get it faster.
A commercial project of 150 kW under today’s rebates would earn roughly $148,000 over five years, but for rebate applications submitted after May 1, that rebate drops to just $66,900, a reduction of 54.7% leaving nearly $81,000 waving bye-bye. Brutal.
All is not lost, yet. We still have a month and if you act RIGHT NOW you can still take advantage of the higher rebate rates! To lock-in the higher rebate, we need to get your energy usage, do a site evaluation, send you a proposal, have you accept the proposal and sign a contract, and we need to get your rebate application on file before May 1. (I feel a bit like our friends at KPCC - “we need 67 people to call in the next five minutes to meet this challenge…") Yeah, that’s a fair amount of work in a short time, but if you jump on this opportunity, we can make it happen and you can save some serious money! So don’t miss the boat… Call us, or click on the “Let’s get started” link here to begin.
Solar rebates are rapidly becoming an endangered species, but there are still a handful of refuges out there for the lucky few who reside in those areas. Here is our update on who is offering what as of January, 2015.
Although there are lots of ways to approach this, we figured that the most entertaining would be to rank-order each utility in the Run on Sun service area from best to worst in terms of their rebate program (and we will toss in a handy summary chart at the end).
Beyond a doubt, the best run solar rebate program in our service area is provided by our hometown utility, Pasadena Water & Power. The folks at PWP have figured out how to provide generous rebates on a predictable schedule while keeping bureaucratic annoyances to a minimum. Boy could its neighbors learn a thing or two from PWP!
Here are their numbers as of today:
Residential: $0.85/Watt EPBB; 12.9¢/kWh PBI.
Commercial: $0.85/Watt EPBB; 12.9¢/kWh PBI.
Non-Profit: $1.60/Watt EPBB; 24.2¢/kWh PBI.
Keep in mind, those numbers have been in place for a long time (since 2012!) and we expect them to drop some time this year.
Anaheim is offering some big rebate numbers, but they offer a ridiculously small window of opportunity for snagging them. Specifically, the window is about to open and you need to submit a rebate application between today, January 15, 2015 and two weeks from today as the window closes on January 29! After that you are out-of-luck until the next window is set. For those who can jump on the opportunity, here are the numbers:
Residential: $1.25/Watt EPBB; n/a PBI.
Commercial: $1.10/Watt EPBB; 11.0¢/kWh PBI.
Which brings us to the problem children…
Azusa has a rebate program, maybe. But what it really has as of now is a waiting list. Good luck with that.
Burbank and Glendale feel like the same city so its not surprising that their local utilities seem to act in lock step. Both utilities arguably offer rebates, but unlike PWP - their more intelligent neighbor to the East - neither BWP nor GWP can figure out how to keep a rebate program open for more than a few weeks (days?) at a time. They say they are victims of their own success, but we see it as a sign of bad planning. (Oh, and don’t get us started about GWP’s alleged Feed-in Tariff program which after a year and a half is yet to have a single application submitted! Genius!)
As for now, all the unfortunate residents of these two communities can do is wait until the new fiscal year in July and hope that some funds will be allocated.
In SCE territory the party is officially over - there are no more rebate funds available, and despite the Governor’s call for 50% of electricity to come from renewables by 2030, there are no moves a foot to refund the CSI program. This is unfortunate beyond the lack of funding - with the demise of the CSI rebates, so goes the CSI data since that was only gathered as part of the rebate process. As a result, we lose a major solar incentive along with a major source of market data for the largest solar market in the country! More genius! (Here’s a thought - since SCE still requires us to go through the interconnection agreement process - via email - why not collect the data that way?)
LADWP offers a rebate, but they have the most excruciating process ever for getting it. (Think of that wealthy Uncle who could easily help you out, but is going to make you bow and scrape before he cuts loose with some ducats, and you get the picture.) Moreover, non-residential rebates are going away in favor of the Feed-in Tariff program, but for small commercial or non-profit customers, that option simply doesn’t pencil out.
For those residential customers with the patience to outlast the bureaucrats, here’s their rebate:
Residential: $0.40/Watt EPBB; n/a PBI.
Frankly, that’s just not worth the trouble.
So here’s the overall results for all of these utilities:
While rebates are going away, the 30% federal tax credit is still in place, and will continue through the end of 2016. Carpe diem!
UPDATE - We heard back from BWP - details at the end of the post…
The wizards at Burbank Water and Power have announced their solar rebate program will resume, but only for the lucky few who happen to be facing West. Here’s our take.
Having a stable, predictable solar rebate program is the key to making a solar program successful. Municipal utilities like Pasadena Water & Power, and investor-owned utilities (like SCE) participating in the California Solar Initiative, have had great success with their programs.
Then there are other munis, like Burbank Water & Power (BWP), that just can’t seem to get it right. BWP, like its similarly misguided neighbor, Glendale Water & Power, has had an on-again, off-again rebate program that baffles all who attempt to make use of it. Now, for a brief moment, BWP’s solar rebate program is on-again, sort of. During the month of August, potential Burbank solar customers are allowed to submit rebate applications (submission deadline is August 29 at 5:00 p.m.) for a lottery to be held on September 8th. The lucky 60 residential and 15 small commercial (<30 kW) customers who make the grade (no details on how the auction will actually be conducted have been released) will be advised of their good fortune by September 12th. Rebate amounts are $0.96/CEC AC Watt for residential and $0.73 for small commercial.
But wait, there’s more.
For the first time in our experience, a utility is limiting rebates for solar systems to only those which face in a generally westerly direction. In fact, systems facing true south are completely ineligible for rebates (as shown in the image to the left), even though such systems are the most productive!
BWP is essentially precluding the overwhelming majority of building owners from even having a chance at a rebate in their lottery system.
This continues a trend we have seen with other muni utilities (GWP we are talking about you) where solar programs are designed to be unsuccessful. It will be interesting to see if we can extract any data from BWP about the results of their lottery.
BWP’s Stated Rationale for Restricting System Azimuth
But why the restriction in the first place?
According to BWP, it is to insure that the power produced comes closest to overlapping with BWP’s peak afternoon demand from 4-7 p.m. Thus to qualify, systems have to be oriented between 200 and 270 degrees and have a minimum tilt of 5 degrees.
That seemed pretty arbitrary to us.
While we could understand a utility wanting to limit providing rate payer money to systems that yield the maximum benefit to those rate payers, there is certainly nothing magical about a limit of 200-270 degrees. In fact, somewhere around 270 should be the sweet spot for afternoon production, with a fall-off on either side. So why cutoff systems beyond 270 degrees?
We decided to run some models using NREL’s PVWATTS tool. We assumed a 10 kW system at a 10 degree pitch (a common residential roof pitch) and accepted the other defaults for the model. We then calculated the hour-by-hour output for systems with azimuths ranging from 200 to 330 degrees. Here are the results for the critical hours from 4 to 7 p.m.
All of the azimuth angles in the green box are acceptable to BWP, whereas all of the azimuth values in the red box are deemed unacceptable for a rebate from BWP.
But here’s the thing… see that green horizontal line? That represents the 4-7 p.m. output for our hypothetical array with an approved azimuth of 200 degrees. Yet five out of six azimuth values modeled here that are rejected by BWP, actually produce more power during the critical period than does our approved system at 200 degrees!
So what exactly is going on here? BWP’s asserted rationale does not hold up to scrutiny. Which begs the question, why, really, is BWP so seriously limiting who can participate in their lottery? It certainly is not justified by their desire to maximize 4-7 p.m. production. If that were truly the case, they should include azimuth angles all the way to 320 degrees. They would get more timely power production while opening their rebate lottery to many more potential customers.
How about it, BWP, what is going on here?
If you are a potential BWP customer who falls outside of the “accepted” azimuth band, you might want to contact the Solar Support program managers:
John Joyce: firstname.lastname@example.org or
Alfred Antoun: email@example.com
If you get a response, please add it to the comments.
UPDATE - We heard back from John Joyce, Solar Support Program Manager at BWP, about the outcome of the lottery process. According to Mr. Joyce:
105 lottery entries have been submitted and the budget is sufficient to allow each of these applicants to participate, therefore no lottery will be held.
We have a further inquiry in to Mr. Joyce to see if there is still budget left over to allow more applications going forward. We will update this again if we hear back.
Last week LADWP responded to its critics by announcing major changes in how its solar program works. In a widely distributed press release, LADWP said its actions were “aimed at reducing delays, streamlining the program, and increasing transparency." Or in other words, providing participants with some hope that one of the most difficult jurisdictions in which to install solar might finally have a chance to live up to its potential. Here’s our take.
There can be no doubt that LADWP is in serious need of improving how its solar program works. Indeed, earlier this month we wrote a piece about Why “Soft Costs” are so Hard (particularly in LADWP territory) and in January we wrote in LA: Where Good News goes to Die, how the LA Department of Building and Safety insisted upon adding their own, entirely redundant, testing regime on new solar products, thereby delaying their introduction in the City, even though those products were UL listed and approved for use everywhere else in the State of California by the California Energy Commission.
At the time we appealed to LA’s new major to fix this:
We suspect that the Garcetti Administration could make this go away tomorrow—so why don’t they? Given the Mayor’s claim to green cred, why not call a meeting with appropriate stakeholders: installers (including small installers), manufacturers, and department heads and lets cut through this unnecessary nonsense and make it easier to install rooftop solar in the biggest city in the biggest solar market in the country. It’s about time.
Now we have no idea whether anyone at LA City Hall reads this blog, and we are certainly not the only folks who have been speaking out about the problems in LA, but last week’s announcement does appear to have picked up on these themes. Here’s how LADWP’s new General Manager framed the issue:
“We recognize that our solar customers have become frustrated with longer than normal response times and the challenges of navigating through the application, review, inspection and rebate processes to receive the incentives and turn on their solar systems,” said LADWP General Manager Marcie Edwards. “We want to make it easier for customers to go solar so they can benefit from the city’s abundant sunshine by controlling a portion of their electricity costs, while helping to green the grid.”
To which we say, bravo, but the devil is in the details.
So what exactly is LADWP promising to do? Quite a bit, apparently, including (from the press release):
- Doubling the number of staff to expedite processing applications and issuing rebate checks.
- Hiring new staff members on a permanent basis to improve response times to hotline calls
- Streamlining the lease application review process
These are all good steps, but if folks who are brought in to review applications don’t understand what they are reviewing, then simply having more bodies will not improve the process. Maybe DWP could bring some actual installers into the training process. Why not pay them to sit down with your new hires and go over the materials being submitted via PowerClerk so that there could be a better understanding of what those materials mean? I’m guessing you could get some volunteers to assist with this process, for a price, and that would improve things for everyone.
In any event, to help increase the transparency of these efforts, DWP is also creating what they are calling “two Mayor’s Dashboards to keep customers informed of the progress and improvements” to the program. These dashboards are to be updated weekly—here is a portion of the dashboard as of March 24:
This shows that the delay in getting a rebate reservation reviewed is presently two months or 56 days—which would in and of itself be a significant improvement on the 78 days we recently endured. By the end of April, DWP is hoping to shave another week off of that and by the end of May to have cut it all the way down to just three weeks, which would bring DWP in line with its neighbors in SCE territory.
Unfortunately for those unhappy customers awaiting a rebate, your delays will get worse before they get better, with payments taking a full quarter of a year by the end of April. Ouch.
The announcement was not confined to just improvements at LADWP, apparently Building and Safety is also getting into the act. Again, from the press release:
Concurrently with efforts being made at LADWP, the solar permitting process at the Department of Building and Safety is being streamlined and simplified, with the vast majority of residential permits soon to be available online and additional training of field inspectors to deliver consistent and timely customer service.
These efforts are expected to save solar installers – and their customers – hundreds of dollars on solar PV systems by reducing trips to DBS for simple permits and ensuring that inspection issues are dealt with promptly. As this streamlining process moves forward, DBS will work with industry stakeholders to continuously deal with the introduction of new technologies in this rapidly evolving sector.
Heavens, be still my heart! Who knows, perhaps someday soon we will be able to skip the whole, “LA has to test everything itself just because it can,” phase and be allowed to deploy best-in-class technology as those products become available on the CEC list—just like we now can in every other jurisdiction. (Along those lines we have heard that the Enphase M250 has been approved and that the final certification should issue shortly. Finally.)
All and all, these are very encouraging noises coming from the City of Angels, and we can only hope at this stage that positive changes will match the promising rhetoric. We will be waiting to see… watch this space.
