Our Florida Solar Panels – Year 1 Report

Our solar panels!

Our solar panels!

It was just over a year ago that we won the lottery. Well, it was more of a race of sorts – a race to get accepted into the Florida Power and Light (known as FPL around here) Solar Rebate Program. As it turned out, the solar rebate allowed us to install a photovoltaic system (solar panels on our roof) that would provide our house with its electricity needs for decades and get a very large rebate from FPL that would cover about half of the cost. Since Federal tax rebates cover 30% of the cost (and the rebates stack!), that meant that we would essentially be installing these solar panels at an effective 80% discount after the two rebates, slashing the payback period on them dramatically (to around 5 years instead of ~25 years).

But in order to get our rebates, we needed to act pretty quickly. The system had to be installed, inspected, and up and running within 90 days or FPL would pass our rebate amount ~$15K on to the next customer on the waiting list. And since FPL was saying that this would be the last year of the solar rebate program (which so far is true), we knew we wouldn’t have this opportunity again.

Probably as a result of the rush, some of our understandings of how our solar system would work with the grid haven’t really panned out exactly as I had anticipated, so the return on our investment isn’t *quite* as high as it might be otherwise. But it’s still pretty darned high, so we’re not kicking ourselves in the shins.

But first, the good.  

Production Was Right In Line With Expectations

Our solar system went on line right in time for our May billing cycle, but our billing cycles end mid-month, so these numbers represent energy use and production for the period of April 15 – December 15, 2015.

During those eight months, there were some when our production was on the high end of the expected range our solar installer had provided us, and some when our production was on the low end of the expected range. But on average, our production was pretty much spot on the estimate of 1,027 kWh that our system was designed to produce on average. (The system was designed to produce enough to satisfy 100% of our average energy needs from 2013 and 2014, but not more.) In fact, our records show that over the course of those eight months, it was within 10 kWh of that value, recording 8,206 kWh produced instead of the 8,216 that were projected on average.

And if you want to get really detailed about it, our records probably undercount our production by at least that many kWh since there was about a week when our solar system was producing very well, but there was an error with our reader recording the output and it was only recording data from about two-thirds of our panels instead of all of them.

But Our Energy Needs Actually Dropped

Our energy usage actually dropped in 2015, from an average of using 1,010 kWh used on average in these months in 2014 (which was low compared to 2013) to using an average of 935 kWh, which was surprising, especially considering there were months in this period when we literally didn’t have walls due to our giant kitchen remodel.

Look, Ma! No walls!

From April through July, we didn’t have walls or a ceiling in our kitchen and dining room, a space that represents approximately 20% of the square footage in our house. And while I tried to keep the A/C off as long as possible not wanting to waste electricity cooling the outside, I lost that battle sometime in April after we stapled some of our new wall and ceiling insulation in place. Sleeping with the sliding door in our bedroom open was not a long term solution despite my not wanting to “waste” energy.

Our renovation also saw us increase the volume of the kitchen and dining room by ~35% due to us changing the ceiling line and moving a wall, transferring space that was inside our garage and attic to inside the house. So we had more indoor climate that we were using electricity to control the temperature of.

We knew we would be attempting to counter act that increased need for electricity by using more energy efficient materials (insulation and windows) than the builder used back in the mid-80s, but it remains a shock to us that they seemed to have more than made up the difference since after my initial protests against wasting energy by using the A/C when we didn’t even have insulation up and the house wasn’t really sealed at all, it seemed like we used the A/C pretty much as normal after that.

This meant that by the end of our December billing cycle, we had built up a whopping 729 kWh reserve of credits with FPL (and I was planning on letting Mr PoP crank up the heat without telling him he needed to put socks on first as soon as the weather started to get cold*), and this is where one of our solar misconceptions comes into play.

Misconception #1 – kWh Credit Expiration Dates

When I was doing all the research on solar panels and talking with our solar consultant, I was told: Some months you won’t use as much energy as you produce. When that happens, the excess kWhs are credited to your FPL account for you to use in months when you use more than you produce. But kWh credits expire after a year per Florida law, and when they expire they get paid out at the wholesale rate, which is much lower than the retail price.

It was because of this clause that it absolutely does NOT make sense to “oversize” a solar system down here since the cost of the additional panels would never be made up with reimbursements at these low wholesale energy rates.

With that description, which was about the same as the description that *was* on FPL’s site at the time, I assumed that meant that if I earned kWh in April, I had until the following April to use them, so they would expire on a rolling basis if we ended up with extras. But that was apparently incorrect (and FPL’s website has now been updated to more accurately reflect what happens to your kWh credits with the year end cash out).

In short, any credits you have left in your “reserve” at the end of your December billing cycle (whether they were generated during your December billing cycle or the January prior), get cashed out at the wholesale rate. And that wholesale rate is ridiculously low – even lower than the ~3cents/kWh I had been told had happened in previous years. I’m not sure whether this year was lower than usual due to declining oil and natural gas prices or what, but we were credited less than 1.87cents/kWh for our year end reserve balance. Our 729 kWh of credits disappeared from our account and were replaced by a whopping $13.63 credit.

In an instant, we went from being kWh rich to being kWh poor. I was not thrilled!  We even had to PAY for 77 kWh on our January bill… so sad. Granted, the cash out of our 729 kWh (even despite the crappy exchange rate) covered the cost, but there wasn’t a ton left over after that. Here’s hoping that we start to have sunnier weather and don’t have to buy any more kWh for the rest of the year! After all, our bills aren’t as small as I thought they were due to the disappearance of my FPL On Call Credits.  Which brings us to misconception number two.

Misconception #2 – FPL On Call And Solar Panels

FPL On Call is another way to get discounts on your electric bills. I wrote about it here when we first had the system installed in our home, but the short summary is this:

In exchange for giving FPL limited authority to turn off the power to major devices in your home (A/C, heat, pool pump, water heater) during periods of high energy demand in your geographic area, FPL would credit your account a few dollars per month. For us, it amounted to $137 in credits each year and we never once noticed FPL On Call being activated. (If you’re not home or actively using that device when they activate your On Call, you’d never know if it happened or not.)

When we were researching the solar panels, we knew we’d still have a flat $8/month customer fee to keep us connected to the grid. But since we were earning an average of more than $11 in On-Call credits every month, we had thought they would cancel each other out and leave us without a cash outlay most months. In fact, I called FPL and asked if the solar panels would have any impact on our participation in the On-Call program, and was assured that they did not.

Even after our On Call credits disappeared from our bill the first month that we had our panels up and running, I called and they said that was a mistake and I would get those credits. And that didn’t much surprise me. After all, our having solar panels does not affect the FPL On-Call program at all. With our On-Call box, FPL can still disable our major appliances if they needed more energy. They would just be taking a higher proportion of the energy that was being produced by our solar panels at that moment than before the On-Call was activated.

But after 2 or 3 months of calling in like this asking “where the heck are my On-Call credits” and being promised that the error would be corrected, finally a phone rep in the On Call department informed me that the policy is that in order to be eligible for On-Call credits, you had to be buying a minimum number (n-hundred, where I can’t remember what the value of n was) of kWh per month. And due to our solar panels, we weren’t meeting that minimum purchase requirement. She said that had always been the policy but that we had always met the minimum so had never noticed it. I asked her to send me a copy of a document where this policy would have been in writing since I never saw it and several reps I had already talked to hadn’t mentioned anything of the sort, and received a flyer for On-Call that did NOT contain this policy, but of course contained language stating that FPL could change the policy at any given time.   Sooo…I gave up fighting and calling in. I think it’s BS, but it’s BS that’s not worth my time for $8/month. So instead of a $0 bill like we thought it would be most months, our bill is $8 most months.

We still have the On Call system installed in our house, so FPL still accrues the benefit of having that usage flexibility, but without accruing any of their cost savings for it to us. In a way, that annoys me. But at the same time, I also think that it’s far more environmentally friendly to allow the utility company to shift the load and not over-produce in order to handle peaks or avoid brown-outs. So for now, the On Call system is still activated in our house and I choose to view it as something nice we do for the environment rather than an effort to save money.  If it ever becomes a big inconvenience to us, I reserve the right to have it dismantled since we’re not getting any benefit from it.

The Numbers – Year 1

The combination of these two misconceptions (hopefully we’ve now found all the “gotchas”) means that our solar panels aren’t quite as good an investment as we thought they would be originally. But it’s pretty freaking close.

Instead of an average bill of ~$103 as it was in 2013 and 2014 (which includes our On-Call credits for most of those months!), our average bill is probably going to be close to $8.That amounts to an average decrease in our monthly bill of ~$95.

Using the Rule of 300 (CanIRetireYet has a good explanation here), a reduction of expenses to the tune of $95/month is roughly equivalent to having investments that you live off (using the 4% rule) totaling:

$95 * 300 = $28,500

Though the published price of our solar panels was pretty close to that, $30K, after our rebates, we will have paid much less.

$30.0K install price – $15.1K FPL rebate – $9.0K federal tax rebate = $5.9K net cost

So we paid $5.9K for the equivalent of having $28.5K in investments in our bank account (plus the increase in our property value). That’s not quite as good as it would be if we got the equivalent of $103*300 = $30.9K if our bills were $0 as I had thought would happen. But it’s still pretty darned good.  And we’d do it again in a heartbeat if given the chance.

 

And that’s pretty much everything that we’ve learned in our first calendar year of solar panels.  Feel free to ask any questions if you have them!  

 

* Cold is relative, people. Also Mr PoP feels it’s his (in his words) “god-given right as a Floridian to not have to put socks on outside of work.”

    Even if you’re still paying $8 a month, that’s awesome and worth the effort, especially with all the rebates you received, cutting the overall cost down.

    I wish my in-laws would get solar panels. They live in a rural area with no gas lines so their entire house is electric. Their house has a simple, two sided low pitch roof and there are no trees anywhere in sight. But living in PA, an old coal state, they would never offer rebates on solar panels at the state level. Perhaps in a few years, that might change. In their country neighborhood, I’ve seen a few solar water distillers: http://www.h2olabs.com/p-313-solarstill-10wdc-solar-water-distiller-compact-kit.aspx?utm_source=referral&utm_medium=cse&utm_campaign=googleshopping&gclid=CjwKEAiAw4e1BRDfi7vghaWU9jESJACzo9juvU42oiPiNpfXHR4kKHXaottiaxAfvE0QPSlGEwAbNRoC1wrw_wcB which are another thing I’ve never hear of! I guess if you’re using well-water, it’s a great idea.

    • We are 100% electric as well since there aren’t any gas lines into our neighborhood. Honestly, I kindof prefer it that way after some not-great experiences with gas.

      Our rebates weren’t actually at the state level, but rather the utility level. I think there had been state benefits, but they ran out before we started seriously looking into this.

      The solar water distiller looks neat – around here the other good use for the sun is for solar water heating. You can use it to heat your pool, but there are also separate systems for your normal hot water usage and rebates through the utility have allowed recent Habitat for Humanity homes to be built with this cost saving system.

      We built an earth-bermed solar home in southwestern Pennsylvania, and while doing the research to design it I discovered that our part of the state has the lowest number of degree heating days you can imagine. This means that solar heating there is almost laughable due to the number of cloudy days. We incorporated all of the passive solar techniques anyway and of course a backup heating system. Because of that, we thoroughly enjoy every ray of sunshine that comes our way as the house is very bright and cheerful. Looking at our electric bill, I can assure you that the solar heating would never do the whole job! We even tried to heat our pool with solar but gave it up. If you are considering solar heating be sure to know your area.

  • I wish we got credit for solar. Apparently we missed a local credit like 5 years ago. I doubt they will institute a new one and I’m not sure how we would find out about it if they did.

    • We missed out on the state credit, only hearing about it when the news was that it was ending. But we were still able to hop on the utility rebate bandwagon even when they weren’t sure they were going to do one more year. I kept up with the rebate news two ways:
      1 – going through the sales/estimate process with a solar installer. Then telling them that the numbers weren’t compelling enough without a rebate, so keep me updated…
      2 – setting a google alert for terms like “Florida solar rebate” “Florida solar incentive” and “FPL solar rebate”
      My google alert told me the FPL rebate program was back for one more year even before the sales guy got around to notifying me!

  • That’s a great runthrough. Honestly, with that rate of return, I would still be quite pleased. Thanks for sharing.

    • Don’t get me wrong, I’m still really happy that we did it. It’s mostly just that it was an unpleasant surprise to go from thinking that we would never have to pay an electric bill again to knowing that we have to pay one EVERY SINGLE MONTH, even if it is small.

  • $8 for utility bills in Florida is still really awesome. I have family that live there and they’d be green with envy if they knew. It beats the $57 I’m paying this month, and spanks the $200 bill I had this time last year.

  • Pretty interesting all around, essentially front 30K today, receive 24K with in a year, then pay $100 year for life, versus $1200 year, breaking even around year 6 as my ball park estimate. That sounds great to me, well done.

    We are probably replacing the A/C unit because of high energy costs for our rental, might have to look into a future solar panel….and the rebate to come back.

  • When we visited Florida for spring break (late Feb/early March) a few years ago, we went swimming in the ocean, wore t-shirts, shorts and sandals, and generally had a great time. And every single person knew we were a tourist because they all thought it was a chilly. It was sooooo nice! Our kayak guide even laughed when we started swimming in the water during a break. He said it was too cold to possibly swim. I suppose that’s what happens when you go from 5F to 65-70ish

    • haha! You would have gotten a kick out of everyone in my office earlier this week. The daytime temps were down in the mid-60s for a couple of days with mornings in the low 50s and we were all breaking out the fleece vests, angora and cashmere sweaters, scarves, etc. I got a compliment on my wool mittens when we stopped at Publix in the evening. =)

      • You wore wool mittens in the low 50s? Okay, I shouldn’t scoff 😉

        Have you seen the video of perceived temps? It goes around on my FB every once in awhile. Basically, it’s a guy driving in the car in the fall. The car says something like 40 degrees (or 30?), and he’s all bundled up, cranking the heat, pulls his hoodie strings tighter, big gloves, etc. Then, we flash ahead to the spring, and the car says the exact same temp. He pulls off his sweatshirt, opens the windows, and is yelling to high heaven. Maybe when it gets cold in the fall, we start to wear a big more. But pretty soon here (March or April), 50 degrees is going to feel mighty warm.

        Heck, even recently — we had a string of days that were -10F, and I was all bundled up. It was 28 the other day, and I didn’t even need a coat to go outside. We really do get used to the weather.

        • Scoff away! I know it’s kindof pathetic. =) In our defense, the heater in the office is on a manual switch for the whole building to switch over from A/C to heat, and they usually postpone turning it on for a couple of days until people start complaining throughout the building. But most of the time, by the time they switch it on, the cold weather is gone and the A/C is needed again. Especially this year!

          I haven’t seen that video, but it definitely makes sense. I know I can adapt *somewhat* given that I did live in a colder (but not -10 cold!) climate for my college years. Even then, though, I still wore way more layers than the locals. I think that’s just what happens when you grow up in the heat!

    What was the final verdict on whether or not the FPL rebate was taxable? We got a rebate from them for our PV system in 2015 as well and I’m working on the taxes now. They haven’t provided a 1099 and their customer services was incredibly unhelpful. It is still my understanding that we need to pay taxes on the FPL rebate.

    • We haven’t yet gotten a 1099 from FPL yet, either. I assume it should be coming soon at which point we’ll get all our documentation to our tax guy for his final recommendation. As of now, my reading of this section of the tax code (https://www.law.cornell.edu/uscode/text/26/136), I believe that they are non-taxable. Since our system is a Tier 1 system, and it not considered a small power plant or cogeneration facility (which I believe Tier 2 and Tier 3 systems are), I don’t believe we are included as an exception to the non-taxable benefit.

      Disclaimer: This is my NOT-A-CPA reading of the tax code. For actual tax advice, I would consult a professional familiar with your personal situation.

      • Daniel

        Thanks for the feedback. I spoke to a person in FPL’s Net Metering Department this week who then called a friend who used to work in the now disbanded Solar Rebate Department. The friend told her that FPL doesn’t issue 1099s because the rebate isn’t taxable. This is third hand information and 1099s don’t need to be received until February 17 (as best I can tell), but FPL might be right though I think there’s a catch.

        It looks like 136(a) does exempt the rebate from taxes but 136(b) appears to require rebates received to be taken from the amount used for the credit. So in your example the $9.1k rebate would need to be excluded from the $30k purchase price so that you would only be eligible for a 30% credit on $20.9k. $20.9k * .30 = $6,270 federal tax credit rather than the $9k federal credit I know you were expecting. You did a good job changing my mind once this week, but that is how I read the law at the moment (I’m also not a CPA). For what it is worth, that is how this company reads it as well: http://blog.recsolar.com/2014/01/how-to-calculate-the-30-federal-investment-tax-credit-for-solar/. The IRS webpage has a non-precedential letter to a taxpayer that allows the taxpayer to get the full 30% credit on the purchase price because the taxpayer will pay tax on the money made selling REC credits to the utility: https://www.irs.gov/pub/irs-wd/1035003.pdf. It is worth noting that my installer was of the opinion that we could get the credit for the full purchase price AND we had to pay taxes on the rebate amount though I no longer think the law supports this position.

        Even if it does end up costing an extra $2,730, I still think you got a very good deal.

        • The wording is weird. Our installer definitely seemed to think that we would get the tax credit based on the full price, pre-rebate, so I think we’re going to defer to our tax guy and see what he says. In previous discussions, he did say that the basis of the panels (and thus the increase in basis of our house) would be offset by the FPL rebate, but that’s kindof moot since the value of our house is so far beneath the exemption level. That and we have no plans to sell it.

  • And you wrote this the day before it got freezing cold in Florida! (At least in Orlando, we were wishing we’d had more layers on the 23rd!) Nice and warm on the 22nd to close to freezing on the 23rd.
    I would love to get solar panels on our house, but the cost doesn’t make up for it without a state benefit, which PA is unlikely to give. We might do it in a few years once our savings are refilled from buying the house, but it’s not looking like a great ROI for Pittsburgh.
