Happy New Year - the Solar & Storage Tax Credit is Extended!

Ok, so of course it took some last minute drama - this is 2020 after all - but the extension to the federal tax credit for solar and storage has been signed into law!  Read on to see what that means for you!

State of the Law Going into Deliberations

New project for the New Year!

This new project will get the full 26% tax credit next year!

As readers of this blog would surely know, the federal tax credit that had been set at 30% for several years, dropped down to 26% in 2020 (just the first of many not-so-desirable outcomes for a year that would see so many!), and was scheduled to decline to 22% for 2021, before expiring completely in January of 2022 for residential solar projects. 

We have written before that the solar tax credit was quite popular on both sides of the aisle, so there was always some hope that the current credit rates might be extended, but that was by no means a sure thing.  Fingers crossed and all that!

A Bill is Born!

As the negotiations between the Trump Administration and Congressional leaders progressed to try and provide economic stimulus at a time when many are out of work, too many facing potential evictions, and state and local governments facing severe challenges, word came out from CALSSA that the extension of the tax credit was in the draft bill!  Then on December 21st we learned that the extension was in the final bill that was being sent to the President!  (For those who are true gluttons for punishment, here’s a link to the Bill, and the language for the residential extension is on page 4,915!  Crazy, right?)

Excited by this most welcome development at the end of a dark year - and just in time for Christmas! - I was ready to write this blog.  But hey, this is still 2020, so I resolved to keep my powder dry until the Bill had actually been signed!

Drama

Seems my hesitation was warranted, as the President declared the Bill - negotiated by his Administration - a “disgrace” and threatened to veto it!  Instead insisting that the relief payments be substantially increased (something his own party rejected) and the “pork” in the bill be removed.  (News coverage of the President’s displeasure focused on exemptions for “three-martini lunches” (who is doing that these days?) or depreciation schedules for race horses!  The solar tax credit did not seem to be part of the pork in question.)  Of course, one man’s pork is another man’s livelihood, and besides, you cannot really take an agreement that took literally months to hammer together and then redo it in days.  Didn’t the President ever see, “I’m Just a Bill?”

All’s Well that End’s Well

So after much Sturm und Drang, on Sunday the Bill became a Law!  Which means we can tell you exactly how things will progress going forward on the tax credit front:

The 26% credit will now continue for projects “placed in service” between now and the end of 2022.  The 22% credit will apply to projects placed in service between January 1, 2023 and December 31, 2023.  Projects that go into service after January 1, 2024 will receive no credit under this new law.

Given the stimulus value of solar and storage projects - to say nothing of their environmental benefits - this is a most welcome development.  And for projects that got delayed due to the pandemic, the full 26% credit will still be available next year - a relief to many homeowners and solar installers who have been up against the clock.

In the end, the process was messier than it needed to be, but the job got done.  Here’s hoping that 2021 and 2022 can be real boom years for the solar industry, and the broader economy as well!

Installing Solar in a Time of Lockdowns

Editor’s Note: As Los Angeles County sees new COVID-19 cases spiking to over 5,000 per day, we wanted to update our followers and potential clients on how things are shaking out.  We just learned that the wife of one of our roofers is ill with the disease and he is in quarantine. Needless to say, we are hoping for her full and swift recovery.  So while this is anything but business as usual, we are still here and working, albeit moving slower than we would like.  We asked Sophia to remind you of just how we work and let you know that we are looking forward to hearing from you soon!  Take it away, Sophia!

Sophia MazurekRun on Sun is Very Much Open!

Despite the COVID-19 restrictions, we are still safely operating here at Run on Sun! The great thing about installing solar is that it requires little close-client contact! When we receive new inquiries, we are able to complete the entire solar install process from site evaluation to final inspection at a distance, and of course, masked. We prioritize your safety and our safety over everything.

Since we are still open and currently working on projects, we want to give you a little insight on the Run on Sun process!   

Since 2006, we have been installing quality solar and storage systems. We pride ourselves on being 100% up-front with our potential clients. As we all know, solar can be quite the investment! It is important for us to make sure each system is going to have economic benefits and will be valuable to the home. These benefits can greatly vary based on location, roof factors, and shading. We want to assure that you are not going to be putting in more money than you are getting out. Your solar system should eventually result in an investment income. In other words, going solar with us will greatly reduce or eliminate your electric bills and will have an economic return! Unfortunately, there are always going to be some houses that will not reap the benefits of solar.

Oscar the RoS drone!A site evaluation with Run on Sun is an easy, stress-free process! First, we will collect your energy usage history to determine your potential system size. We will then come to your property with our drone (we call him Oscar!) and capture aerial images, which will give us detailed monthly solar-resource data from your roof. (We aim for an average annual sun exposure of 80% or more to go forward with a project.) After we have gathered all necessary data, we use a sophisticated software service called Scanifly to create a precise 3D model of your home with solar included. A comprehensive proposal of the system, quote, and savings will be sent to you free of charge!

Run Down of Our Selected Products

Here at Run on Sun–we value quality and have carefully chosen our products from extensive research and testing. Our go-to panel manufacturer for each system is made by LG (you know, the Life is Good folks!).  LG’s  durable and reliable panels have been giving us the most efficient results for years. We trust LG to provide us with reasonable prices, amazing quality, and impeccable aesthetics. In addition, each panel has a 25-year warranty so there are zero financial penalties if anything were to malfunction!

We also use all Enphase products, including the IQ7+ microinverter and the Envoy monitoring device, which allows us and our clients to view system production. We are also now installing the Ensemble Energy Storage System, that can be a terrific addition, particularly for clients in the SCE service area. We have been partners with Enphase since 2009 - we installed system ID 1,470!  They are re-imagining the solar industry by making the process easier, faster, and by far–more reliable. Each microinverter comes with a 25-year warranty and allows for complete customer inclusion by making their monitoring system comprehensive and mobile-friendly.

Why go with Run on Sun?

The solar market is competitive and there are a lot of installers out there! Here at Run on Sun, Founder & CEO Jim Jenal is NABCEP certified, and we are constantly updating our knowledge as the solar world continues to evolve. The way we view solar is a little different from other companies. We recognize how big of an investment going solar can be. However, it is one of the best things you can do for yourself and for the world. We want to make sure our customers understand every single aspect of the process and are getting all questions answered thoroughly. For us, it’s not about selling a system. It’s about making sure solar is going to be beneficial for you. Run on Sun is always 100% transparent with each client. If we run the numbers and there is little economic advantage–we will highlight that from the start. Our motive to install solar stems from our passion for the planet and for the people. We put in the necessary time and effort to ensure the highest quality of system is achieved, and we go the extra lengths to help our customers in any way possible.

So–what are you waiting for? Get a free solar quote now! We would love to hear from you.

From Drone to Done!

Back in February we wrote about how Run on Sun had taken a giant step forward technologically in entering the Drone Era for doing site evaluations.  That giant leap was enabled by our learning about Software-as-a-Service provider, Scanifly and the super cool software that they had developed to transform individual drone images into a three-dimensional model that would allow both a detailed shading analysis and precise layouts to be performed at your computer without ever going on the roof.

Sadly, no sooner had we gotten on-board with Scanifly than we went into Covid-lockdown and lots of things got put on hold.  But now that we are building projects again, we thought it would be worthwhile to compare how closely our Scanifly model compared to the real world!  Check it out…

Starts with the Drone

The process begins by a drone flight that captures both contextual images - using a Point-of-Interest flight where you identify your center point, back off to a radius that will include all shade elements, and then fly that circle taking images every 2 seconds or so (our drone, a Mavic Air, does that automatically) - and detailed images closer in to where the array will be placed.  Here’s an example of a contextual image:

Context drone image

The garage face is where the array will go, and we are far enough away that surrounding trees will be included when we fly our orbit.  Now here’s an example of a detail image:

Drone detail image

Here we are much closer to the surface of interest.  The beauty of what Scanifly does is that it takes these disparate images (we used a total of 113 separate images) and stiches them together into a model from which you can do your layout.

Design Time

Now that the images have been upload and Scanifly creates the model - a process that takes about a day - we are ready to do our design.  The software allows you to build in “keepout” areas for things like fire setbacks, as well as obstructions like vents or skylights that cannot be moved.  You select the PV module that you will be using and then the software creates a placement for you that you can then modify as necessary.  Here’s what that looked like for this project:

We have placed the array at 18″ off the ridge, and we are really going from edge-to-edge!  (The yellow dots are the vertices that we marked in the model, the red line is our setback line.)  We are using LG 350’s as our modules, and we really have no room to spare - these dimensions have got to be right!  So how did we do?

Build It!

I have to say, I like how this turned out!  Click on the buttons to fade from the design image to the as-built (thanks to Sophia Mazurek for getting these images to line up).

How cool is that?

We’re hooked! Many thanks to the entire team at Scanifly - you have made our work safer, easier, and better!

Examining the Flaws of California’s Resource Adequacy Plan

The California Independent System Operator (CAISO), California Public Utilities Commission (CPUC) and California Energy Commission (CEC) have issued a Preliminary Root Cause Analysis Report following the summer wildfires. Throughout this report, the collective determined that California is unprepared for the current climate and highlights the need for greater funding and revision into Resource Adequacy planning. 

The wildfires in August led to power outages all over the state. A huge impact was experienced in the natural gas sector resulting in 1,400MW to 2,000MW of forced outages. In addition, unprecedented spikes in energy demand occurred on August 14th and 15th–the same time as the initial outages. This increase in energy consumption was not only unexpected but was unaccounted for in the planning process due to the lack of certainty surrounding COVID-19. 

According to CAISO president and CEO Eliot Mainzer, “This preliminary root cause analysis is an important step in helping us learn from the events on the 14th and 15th of August.” The main focus is shifted towards detecting weaknesses in resource prediction and how to adjust to new and ever-changing energy patterns. Resource Adequacy is determined by electricity demand at peak hours of consumption. Assuming there is enough electricity to withstand peak demand, there should be plenty to suffice the grid at other times. Right? 

Demand versus net demand graph

Unfortunately, it is not that simple! Instead of one single peak demand period, we now experience “multiple critical periods during the day,” according to the report. This is due to a rapid growth of solar integration within the grid, resulting in a net peak demand. As more renewables make their way into the grid, such as solar and wind, peak demand is ‘offset’ by these resources. Therefore, net peak demand is renewable energy production subtracted from demand.

Net peak demand is difficult to determine. “Over time, critical grid needs may manifest in other hours, seasons or conditions as the energy resource portfolio continues to evolve…”–which is why implementing backup storage is a necessary step to account for uncertainties in consumption. With more storage, California can increase grid capacity and reform peak demand rates. CPUC has been working with load-serving entities to enhance grid reliability through solar-plus-storage, hybrid storage, and 300MW of wind and solar. The report also pushes for completion of these projects by a targeted date. 

This impactful Root Cause Analysis is exposing the flaws in the energy sector and hitting them head on. With greater realization of the issues at hand, comes greater responsibility to take action and demand change. California is leaning into energy storage as it becomes the most sustainable and efficient solution to combat the heat of summer.

Power Start - Giving Storage Systems a Boost

Ensemble lab

Enphase Ensemble Lab in Petaluma

When you are turning on your AC or other large household appliances, you probably don’t think about how much current these systems require to start-up. Yet many appliances are going to be pulling anywhere from 2 to 2.5 times their regular running current to complete the start-up process. This large change in amperage is what we call a “surge current”.

“Surge current refers to a short-term spike in power demand from a particular appliance to get it started…” For example, when your car battery dies– you have to jump it using another cars battery. “Something similar happens for high load appliances in your home when they are turned on,” suggests Enphase.

With the recent fires and grid blackouts– Californians are coming to grips with the pressing need for solar energy backed by smart storage. The current storage systems on the market have struggled to keep up with surge current loads. This makes it nearly impossible for homes to be independent from the grid. Your system may be able to keep your appliances running, but what happens when they stop? 

According to Enphase, “This inability to handle power-hungry appliances has been a challenge for battery storage systems for years… until now.” 

Into that void now comes the new Power Start™ by Enphase. This technology is designed to help reliably start every appliance in your home during a blackout. Power Start’s unique algorithm detects when a large appliance is trying to start back up and automatically disperses the same amount energy over a fraction of a second. 

This technology can be added onto the Encharge 10 battery systems, which have a continuous power rating of 3.84kWs and a surge power rating of 5.76kWs for 10 seconds.

You can click this link to find common surge current demands within different appliances.

The new Power Start by Enphase is a necessary and vital addition to battery storage systems. This technology will improve reliability and independence from the grid.
