Ensemble Rollout Coming into Focus

On the heels of their video release last month, the folks at Enphase have now published an FAQ page on the entire Ensemble system.  Here are some highlights…

Perhaps the most exciting item is that they are expecting deliveries around Christmas time – what a great gift!  That said, I’m sure quantities are going to be limited at least initially. To that point, however, it looks like there will be a “pre-order” option - though the FAQ page is silent on details or pricing.

The most disappointing answer is that the system will not be compatible with S and M series microinverters, although they are planning an upgrade path, similar to the “Early Adopters” program that they had earlier this year.

Happy to hear your feedback - obviously we are following developments here closely, watch this space.

Enphase Releases Video on IQ8 and Ensemble

Our friends over at Enphase have posted a video to YouTube explaining in non-technical terms what the IQ8 will do for solar consumers, both in the developing world, and here at home.  Here’s the video and some quick thoughts about it.

To quote the video, “Isn’t it cool?"  Well yes, as we’ve been saying for quite some time here, this is waaaay cool.  But here are some other takeaways from the video:

  • Strong endorsement for interoperability with the IQ6’s and IQ7’s that we have been installing for the past year and a half.  But no word about how this will work with earlier versions.
  • The Enpower switch - which is needed to legally isolate you from the grid - is pictured, but still no details.
  • A hint at pricing would be nice!

As far as I’m aware, this is the first, general-public-facing details about the IQ8 and Ensemble that Enphase has released.  It went live on May 28, and three days later is sitting on just under 15,000 views, with 154 up-votes to 6 down-votes.  (What is there to down vote?  Gee, SEDG, troll much?)

This will be very cool technology for our clients, but it will truly be life-changing for folks in the developing world or any place where the grid is unreliable.

Watch this space.

Shortcut Solar Specialty: Roof Leaks!

While those crazy folks over at Shortcut Solar have many distinguishing characteristics, certainly one of the most commonly displayed is just plain shoddy work—and one of the most devastating consequences of shoddy work is a leaky roof. Check out our latest tale of cleaning up after Shortcut Solar…

We recently got asked to give a homeowner a quote for removing an existing solar installation from her garage because the roof was leaking and needed to be replaced. (The array was there when she purchased the home.)  Here’s what we found when we got there: ten panels, installed in a way that only Shortcut Solar could do, check it out…

Reverse tilt!

Ah yes, everyone’s favorite mounting method—not!—reverse tilt on a north sloping roof! Never mind that you are voiding the warranty from the racking manufacture, and putting tremendous strain on all of the components, but heck, it lets you get the panels in more or less the same plane as the south facing panels, right?  Oh, and note the “flashing” method at the base of those columns: cement (and/or mastic), well known for its ability to flex with the torque forces that the wind will exert on this “solar wing” that they have fabricated.

But wait, that’s not all, check out the fate of the south facing panels…

Tree!

Yep, they actually put the array behind a tree!  (The homeowner told us that there had been a similar tree on the left of the fountain, but it died after the array was installed.) Truly the folks at Shortcut Solar were on a roll that day!

So, sadly, we set out to remove the array in advance of the roofer coming in to do their thing.  (The homeowner generously donated the used equipment to a local city college to assist students in their PV classes.)

The details up on the roof were really appalling.  Check this out:

Tree!

That is an end clamp, attached to a rail that is actually below the level of the tile!  The tile above it was “notched” but nothing, at least by now, was in place to keep water from pouring under the broken tile. (The little bit of red mastic is a nice, esthetic, touch!)

Tree!

Or how about this thing of beauty: actually, it is kinda hard to know what they were thinking here.  I can only presume from the concrete in the rail, that they tried to anchor a piece of tile above this, but failed completely.

The panels on the south face were not as awful (apart from being behind a tree), as they had removed the tiles in the area where they were doing their attachments and put down a torch-down layer of roofing material.  But even then they could not be consistent–their single bolt attachments in some places had a 3″ lag screw, but in other areas they couldn’t be bothered and simply used a 1½” hex screw.  ‘Cause, yeah, why would you care about actually getting into the rafters?

There can be no doubt that this installation was doomed from the day it was installed, and I hate giving such bad news to nice people like this homeowner. 

This was in the City of Los Angeles – how on earth did this ever pass inspection?  Sadly, with Shortcut Solar on the job, this is the type of work you can expect. 

It doesn’t have to be like this.  Building inspectors should crack down on this sort of nonsense.  And potential solar purchasers need to do their homework better as well.  Don’t just go with the smooth talker who shows up on your doorstep - he might be working for Shortcut Solar!  Check out reviews, look for NABCEP certification, and talk to past customers.  Together we can make Shortcut Solar, and their shoddy work, a thing of the past!

Zillow Report: Solar Boosts Home Prices by 4.1%

The folks over at Zillow are out with a study of sale prices for homes with a solar PV system compared to those without and the results are pretty dramatic.  Nationwide, homes with a solar PV system sold on average for 4.1% more than those without.  Let’s take a look at their numbers and see what that might mean for a solar installation in the Run on Sun service area…

Let’s start with the data (always a good place to start!)…

home sale prices with PV

(Data from Zillow, Inc., graph by Run on Sun.)

The graph plots the increase in home price as both a percentage (the blue bars) and total dollars (the gold line).  New York city has the highest percentage increase (5.4%), while San Francisco, because of its sky high home values, has the highest dollar increase, a whopping $41,658!  To derive these numbers, the folks at Zillow analyzed homes “listed for sale and sold from March 1, 2018 to February 28, 2019, controlling for observable attributes of the homes, including bedrooms, bathrooms, square footage, age of the home and location."  In other words, these are the very latest data possible, compiled by people who understand real estate prices!

Good looking solarOf course, Run on Sun doesn’t operate in San Francisco, let alone New York, so what does the data say for our neighborhood?  Overall, Los Angeles percentagewise lags the U.S. average - 3.6% compared to 4.1% - but because our home prices are much higher than the national average, the dollar amount is still dramatic: $23,295!  The Zillow analysis does not say how large the solar power systems were on average, but the increase in Los Angeles sales prices is more than enough to cover the cost of installing an average sized system.  

Doing the math, the Zillow study is showing an average home cost in Los Angeles of roughly $647,000.  Here in Pasadena, the average home price is a good deal higher, which would mean that the increase in the home’s value by adding solar will almost certainly cover the cost (and then some) of even a very large solar power system. To be sure, it helps if the system is installed in a way that also makes the home look better (see above), so you will want to avoid Shortcut Solar for your install!

If you are looking to make an investment in your home that will benefit you both now, and when you go to sell, forget the designer kitchen - go solar!

It's Tax Day - what's that got to do with residential solar?

Tax day!At the risk of being the bearer of bad tidings, today is Tax Day!  So—apart from really bringing you down—what has that got to do with installing solar on your home?  Well here’s the thing, for quite some time now, solar installations have enjoyed a 30% federal tax credit that can be stretched out over 20 years.  Indeed, with the demise of all of the local, utility-provided rebates, the federal tax credit has been the last incentive standing.  But guess what—it too is scheduled to go away.  Here’s what you need to know…

For some folks the thought of going solar now is leavened by the belief that something much better will be coming soon.  But aside from the very real opportunity cost that arises from delaying that solar install, there are now imminent tax consequences to consider.  In particular, here is the schedule of declines to the federal tax credit for solar:

  • Now until December 31, 2019 - the full value of 30% on the cost of the system.
  • January 1, 2020 through December 31, 2020 - 26%.
  • January 1, 2021 through December 31, 2021 - 22%.
  • January 1, 2022 - ZERO!

So over the next two years a relatively gentle step down (though 4% on a $25,000 project is still $1,000 you would be leaving on the table) each year, but then it falls off a cliff as the credit goes away entirely!

Moreover, it is important to note that the credit is only available for projects that are “put in service” in the associated calendar year; which for all intents and purposes for residential projects, that means that you have received Permission to Operate from your utility.  And that is where the real issues arise.  We have seen this before—whenever a major incentive is scheduled to decrease (or go away entirely), there is a last-minute rush to get projects installed and PTO issued.  But utilities operate on their own timelines, and as the number of projects pending increases, so does the amount of time that it takes to get approved.

For potential Run on Sun clients, you should know that we will be issuing a cutoff later in the year beyond which time we will not be able to guarantee that you receive PTO this year.  That will be a function of both our pipeline, and more importantly, the pipeline for approval at the various AHJ’s and utilities in our service area.  Watch this space for updates.

Bottom line—if you are seriously considering going solar this year, and capturing that full 30% federal tax credit, Do Not Wait!  Give us a call, get into the queue early, and rest easy, knowing that next year, Tax Day will be a whole lot sweeter!
