Thoughts on Solar

tl;dr - Come Rally with us on June 2, at 10:30 a.m. in Grand Park, DTLA!

As readers of this blog know only too well, the California Public Utilities Commission (CPUC) had proposed - at the urging of the investor-owned utilities (IOUs), that is SCE, PG&E, and SDG&E - a new set of rules for how solar system owners would be compensated for the energy they put back onto the grid.  In a nutshell, that proposal would have pushed the payback period for solar systems to twenty years or more!  In an epic bit of organizing, our trade association - the California Solar and Storage Association (CALSSA) - kicked up a ruckus that was clearly heard in Sacramento, by getting folks to sign petitions, issue public comments, testify to the CPUC for six hours straight, and two very loud, very colorful rallies in San Francisco and here in LA.  (If you missed that, you can read about the LA rally here.)

Thanks to those efforts, the original proposal was pulled back.  But that didn’t win the fight, as the CPUC is still talking about a Solar Tax that would destroy the value of rooftop solar for most Californians.

That’s why it’s time to lace up your protest shoes and attend the…

We need to more than double our impressive turnout from the last two rallies.  That means we need you!  And your kids.  And your friends.  And your kids friends - get the picture?

In case you need more detail - really, this is only about saving rooftop solar in California, so I wouldn’t think too many more details would be required but - let CALSSA’s Executive Director, Bernadette Del Chiaro, give you the Word:

On May 9, the CPUC took an unprecedented step of effectively issuing a new decision in the form of 14 questions. Those questions broke five months of silence, pulled back the curtain, and revealed what the CPUC is still thinking: tax solar and send the value of exports over a cliff. The CPUC has essentially floated a trial balloon to see how much push back they will get for proposing a solar tax (by a different name) and repackaging the solar cliff to make it sound nicer (ACC “plus”). Our job is to push back. Hard. Loud. Once and for all: No solar tax. No solar cliff. Not in California. Not now.

We need thousands of you. RSVP here.

Why June 2? For starters, because silence is acquiesce. Think about it. The State of California just floated a proposal to tax the behind-the-meter use of solar energy, again. Every day that goes by in which people aren’t reacting appropriately (i.e., freaking out), is a day in which the message back to our government is one of acceptance. That is certainly not our reality. If we could have, we would have rallied on May 10!
 
Another reason to rally on June 2 is because the CPUC has literally asked for our reaction to their “new” ideas: tax behind-the-meter solar consumption to the tune of $600 per year for the average customer (NOTE: the tax is not limited to the residential market – commercial market you could be caught up in this tragedy, too) and tie export values for everyone to the Avoided Cost Calculator which they have refused to adjust for the rising costs of natural gas, the crisis in the utility-scale market, and the demands of electrification. The CPUC has asked for our reaction by June 10. June 2 is simply the closest date to June 10 at which the CPUC is holding a meeting. The next meeting of the Commission is June 24 which would be too late.
 
Finally, there is never a good time to leave the office and come down off the roof. Collectively, we build more than 400 solar systems a day in California. That’s a lot of activity. And, with all the disruptions to supply chains along with the increased urgency due to this very campaign (ironically driving more people to solar than if they had promised to make gentle and gradual changes from the get-go), our days are busier and more complicated than ever. I get it. But what’s far more inconvenient and costly than shutting down your office for one day is closing your business or laying off half your staff in 2023 because the CPUC got NEM 3.0 horribly wrong. A stitch in time saves nine. Let’s save our market. RSPV now.
 
Finally, you might also be wondering why we should rally. Aren’t there other ways to make our voices heard? Of course the answer to that is, yes, there are many ways to make our voices heard. We are and should continue to speak out through petitions, letters to the governor, testimony that is being written by Brad now (to be submitted June 10), through media (like this question to Governor Newsom by Politico reporter last week), social media, and so much more. But to really be heard, we need to generate media attention too. We need to get on the nightly news and on the pages of the newspapers. Because when we do that, millions of voters hear our cry and we already know those millions are with us on the issue. 
 
It comes down to you reading this message and deciding to join the fray, the fun, the action. So, please join us in either Los Angeles or San Francisco on June 2. It will be worth your time. It will be fun. You’ll be glad you did it.
 
As always, email me with questions or comments.

p.s. Many people like to theorize about the likelihood of a Democratic governor in a pro-environment state harming the darling of the clean energy economy: solar. Putting aside the lack of understanding of how politics really works up here in Sacramento (hint: follow the money toward the path of least resistance), my ask to you is this: don’t leave this critical decision to political theory. Your active involvement in this campaign – most importantly joining us June 2 – will help make sure we win in reality, not just in theory. Let’s not leave anything this important to chance. Join us. 

This is up to us.  This is our fight.  Get in the game, people!  See you on June 2nd!

On Thursday, January 13, 2022, the Run on Sun crew - and a few thousand of our friends and colleagues - got together at simultaneous rallies in Los Angeles and San Francisco.  Our message was simple: the Proposed Decision from the California Public Utilities Commission (CPUC) would imperil thousands of solar jobs, drive up the cost for solar for everyone (truly meaning that only the most affluent could afford it), and frustrate California’s efforts to address Climate Change.  It is time for Governor Newsom to do more than suggest that the proposal, “needs some work."  In fact, the Proposed Decision needs to be scrapped in favor of a policy that will make solar more affordable for everyone.

Nearly two thousand people gathered in LA’s Grand Park to listen to CALSSA’s Policy Director,  Brad Heavner, and other speakers exhort the crowd to stand strong in solidarity against the CPUC’s disastrous proposal.  We then marched from the park the four blocks to the CPUC’s offices in DTLA.  Along the way we were greeted by cars honking in support of solar - including the driver of a Metro bus!

Here are some images from the rally:

By any measure, the rallies were a success - but there’s still one metric to be determined: the final outcome! Of course, we will write about that as soon as we know more. Watch this space.

Readers of this blog are well aware of the fight being waged before the California Public Utilities Commission (CPUC) as we first wrote about this back in February!  Now we are entering the final stretch in this fight, and quite frankly, we are losing. 

Why, you ask?  How can we be losing the battle to preserve your right to put solar on your home or business, when everybody loves that idea?  The answer is easy: the opposing forces - we are talking about you here, Southern California Edison - have nearly infinitely more money than we do, and they are spending it like crazy.  So how do we possibly fight back?

With you.  And tens of thousands of other folks just like you.

The California Solar and Storage Association (CALSSA) - our trade association - is fighting hard to preserve the value of the investment made by past solar clients, and those in the future.  They have created an audacious goal: generate 200,000 public comments by November 20!  Here’s how CALSSA framed the fight:

“If the broad light of day could be let in upon men’s actions, it would purify them as the sun disinfects” – 1891, Louis Brandeis, US Supreme Court Justice

In 2015, the pro-solar coalition submitted 130,000 public comments to the CPUC on the NEM-2 decision. Today, as we near the homestretch in the NEM-3 proceeding, the headwinds are greater and the opposition better organized. Therefore, we are launching a campaign today to reach our goal of generating two hundred thousand public comments by November 20. Reaching this goal would break the record for the greatest number of public comments received by a state agency in history – previously set by solar advocates in 2015. Simply put, two hundred thousand is a number that the CPUC and the governor simply can’t ignore. It is the sunshine that is needed to fight against the corrupting influence of SCE and the other utilities. 

We cannot afford anyone sitting on the sidelines.  If you own a solar power system, the value of your investment is at stake.  If you realize that rooftop solar is a key piece in how we reduce carbon emissions to combat climate change, that goal is under attack!

It’s easy to join the fight: Mash that button below and tell the CPUC to side with solar consumers and not with the utilities!

Editor’s Note: This is the third installment in our three-part series:
My Electric Bill is So High! Will Solar Help?  
You can read Part One, How High is High, here, and
Part Two, How Do I Find Someone to Trust, here.

With apologies to the Lovin’ Spoonful, eventually you have to make up your mind between those competing bids you’ve received, but how?  Let’s walk through the proposal evaluation process and see if everything that you need to see has been included!

What’s in the Proposal?

Solar proposals come in all shapes and sizes.  Some are very short – just a listing of what will be provided, a price, and a place to sign.  On the other end of the spectrum are proposals that are twenty pages long, most of it boilerplate about what is solar and how does it work, and what a great company this is.  But strip away the boilerplate and are they really giving you much information that is specific to your situation?

What were the inputs?

The old saying, GIGO: Garbage In, Garbage Out, applies to solar proposals too.  In this case, the inputs are your past energy usage, and a detailed site evaluation that looked at your service panel and your roof.  Omit any of those inputs, and the output is likely to be of dubious value, or worse, it will mask the true cost of installing solar at your home, leaving you exposed to costly change orders down the road when the contractor “discovers” something that should have been addressed at the proposal stage!

Your energy usage for the past year is the key input – without it you’re flying blind.  If you are in SCE territory, your potential installer should be asking for access to your  interval data.  For most residential clients, that is hourly usage measurements over the entire year, and that is important to accurately model your savings under now mandatory, time-of-use rates.  Where interval data is not available, monthly, or worse, bi-monthly billing records can be used, but they will not provide the granularity needed to see how the proposed PV system will actually operate to offset your daily loads.

Assuming that interval data is available – we ask our clients provide it through a secure service called UtilityAPI – it is the installer’s responsibility to properly analyze it to know how large a system you need.  As we mentioned in Part One, we use Energy Toolbase for our data analysis as it is the most authoritative tool on the market.  The chart above shows the average seasonal usage for one particular client as processed by Energy Toolbase from the raw interval data.  This shows the average hourly usage over spring and summer, with a very dramatic peak on summer weekends around 5:30 p.m.  Recall from Part One about “low-hanging fruit” – what you are seeing here is an excessive A/C demand that, if it can be addressed, would greatly reduce the size of the PV system needed for this client.

Ideally, this analysis takes place before the site evaluation so that the installer is able to advise the potential client about actions to be taken to reduce their overall usage, and thereby end up with the most cost-effective solution tailored to their needs.

Detailed equipment line items

One of the things that we see on competitors’ proposals that never ceases to amaze us is the total lack of detail regarding the actual equipment that is going to be installed!  It is as if the homeowner is expected to pay thousands of dollars for a generic solar power system – but you wouldn’t spend thousands on a generic car, would you?  Moreover, how can you assess the value proposition of a generic system?  A company that proposes a generic system intends to install on your home whatever is on sale that week.  Maybe you get lucky, more likely you don’t, but in either case, you simply don’t know, and that is no way to make a major investment.

Your proposal should have line items for all of the major components of your system: the solar panels, microinverters, racking, and installation costs.  And those items should be specific, down to the model being selected and the per unit cost.  Only that level of detail allows you to see what you are getting and for how much.

Utility savings analysis

Determining how much your proposed PV system will save you in Year 1 is the key to the entire analysis of the proposal, and it is a two-step process.  First, your historical usage data is analyzed against your current billing rate to determine what your energy costs will be over the next year.  There are a couple of assumptions built into that assessment, namely that both your usage and your billing rate will stay the same.  If you have been in your home for awhile, your usage last year is probably a pretty good predictor of your usage next year.  On the other hand, if you moved in rather recently, or made a major purchase like a new EV, that will skew your usage going forward.  Similarly, last year’s bills were predicated on the exact details of your billing rate structure in effect at that time – and those are subject to change without notice.  So look at what the proposal projects for your bill next year without solar, and see how that compares with last year.

The second part is the more important piece - assessing how  your bill will change now that you have added PV.  Here’s where things get complicated, and a tool like Energy Toolbase becomes essential.  The proposal should show a model of your past usage overlayed by the production of the PV system.

As you can see in the graph above (click for a larger version), the darker blue is the historical usage (we are looking at two days in July), the green is the modeled production from the proposed PV system, and the pale blue is the net energy demand.  At the peak on the right, the PV system is producing 5.22 kW at a time when the historical demand was 11.95, meaning that the net demand from the utility is 6.73 kw – and that is the basis for what the client will be billed.  You can also see that there are periods in the morning when the system is producing more power that the client historically used, resulting in power being exported out to the grid – for which the client is compensated due to net metering.

This is the analysis that must underlie your savings analysis – anything else is simply guess work.

Cash flow analysis – payback over time

Part of any cash flow analysis is the cost of the transaction.  If you are making a cash purchase you know exactly what your transaction costs will be.  But if you are financing through the solar company, or heavens forbid leasing, those transaction costs may well be obscured, it not hidden altogether.  Make certain that you have all the information you need to determine exactly what that deal is going to cost you.

For the sake of discussion, we will assume that this is a cash purchase.  What other assumptions go into a proper cash flow analysis? To start, how long is the period of the analysis?  Ten years?  Twenty years?  Thirty years?  Beware of an analysis that simply says how much money you will have saved in the end, without calling out the period in question!  In our view, ten years is too short, and 30 years is too long.  But whatever the number is, make sure you are aware of it as you compare “total savings!”

Another key assumption is how much will utility rates go up over the lifetime of the analysis?  It used to be common to see rate escalators of 6-7% per annum, but there was no real data-driven basis for that number.  (In fact, long ago we used 6.7% based on a website that claimed that the California Energy Commission had published that figure.  But when we went digging for the source, we discovered it didn’t exist - there was just this circular linking of sites each claiming to have gotten this from the CEC!) 

Over time we have consistently reduced the value that we use for our models, so that now we are using 3%, which we think is reasonably conservative.  But this is really a matter of just throwing darts at a board, and no one really knows what that number will be. Keep in mind that for comparison purposes, you should be able to see what value was used, and the higher the number, the rosier the prediction!

PV systems degrade over time, and that output diminishment should be accounted for in the analysis.  Modern solar panels degrade less than 1% per annum (the LG panels that we use are around 0.5%), but in any event, make sure that is incorporated in the model.

Finally, the value of money in your hand today is, generally, worth more than money you will have at some point in the future.  How much more valuable is a function of the discount rate applied to those future savings.  If the model ignores that, your future savings are likely artificially high.  Again, no one knows what the right number is, but a proper model will account for it and allow you to know what you are comparing.

What’s in the Contract?

Strictly speaking not a part of the proposal, it is not a bad idea to ask to look at the contract before you pick a contractor.  Many solar contracts are very long, written in tiny fonts, with lots of legalese – all designed to make you throw up your hands and simply ask, where do I sign?  But slow down, friend, the devil may be lurking in those details!  Indeed, we have had clients who were ready to sign with another company until they looked at what was in the contract!

Ideally the contract should be written in plain English, it should clearly set forth what will happen, when, and how, and it should be even-handed.

An Important Caveat

Finally, it is important to call out what even the most carefully considered proposal cannot address - future uncertainty; in particular, what will utilities try to do, and what will the CPUC let them do!

Things outside of our control - CPUC & Utilities

If you follow this blog you will know that the solar industry is under constant assault from efforts by utilities – particularly the investor-owned utilities like SCE – to reduce if not altogether eliminate the economic value of adding solar.  Whether it is by lobbying for changes to the net metering rules (which just this past year imposed additional fees, charges, and mandated time-of-use rates), or designing utility rates that make solar production less valuable, there is a constant struggle behind the scenes to undermine the solar investment of thousands of California homeowners.  (And this is not at all limited to California – attacks on net metering and efforts to impose pernicious rate structures are a nationwide phenomenon.)

Things we can control - SolarCitiSuns & CALSSA

Fortunately there are a couple of entities out there that are working hard to preserve the value of going solar.  If you are a California homeowner with a solar power system, there is an organization specifically for you.  California SolarCitiSuns is perhaps a corny name, but its mission is crucial: to organize the political power of California’s thousands of citizens with solar on their homes or businesses, or anyone who wants to be part of advocating for a clean, renewable future.  If you have solar on your home or business, click here to join!   The investment that you are protecting is yours!

 And finally, solar companies, are you a member of the California Solar & Storage Association?  We are, and you should be.  Click here to join CALSSA today! 

Beyond that, rank and file solar workers – installers, designers, finance people, anyone whose livelihood depends on the solar industry – there is an action group that you can join, even if your company is not a CALSSA member!  Joining means that you will get alerts when a crucial vote is upcoming in Sacramento or San Francisco, and give you the opportunity to reach out and show your support for the industry that provides your livelihood.  It’s easy and important. Every solar worker in California – click on this link to join the CALSSA Action Network – the job you save will be your own!

So there you have it - everything you need to know about going solar – look forward to hearing from you soon!
