Run on Sun Enters the Drone Era!

Just about a year ago, we really started thinking seriously about what drone technology might add to our solar installation company. The folks over at Scanifly – with their ability to take drone images and convert it into a 3-D model of a potential solar site, without needing to climb onto a roof, was really appealing. And that got us thinking of other ways a drone might be helpful - as with finished project photography, or inspecting existing systems. All of that seemed possible, but certainly there were obstacles in the path.

Well now, a year later, those obstacles have been surmounted, and Run on Sun has officially enter the Drone Era!  Here’s how we did it…

Research

We started by doing some homework.  Lots of it.  Watching videos to see what it would take to make this happen.  The list was fairly long: what drone to purchase (there are a lot of drones out there!), how do you learn to fly one (safely!), what does it take to do this legally?  And on and on.

Choosing a drone…

Drones come in all shapes and sizes - to say nothing of costs.  Last year LG sent out a professional crew to photograph one of our installations (you can see one of those photos here), and they used a $20,000 drone for the task.  Clearly that was going to be too rich for our blood!  A number of years ago, my good buddy Josh - who is always on the bleeding edge of fun tools - had let us use his drone for shooting some video of our reservoir project. Josh did all the real flying, but I did get to take the controls and found it pretty straightforward to fly.  So we had some exposure to some of the different drones out there.

Our Mavic Air, aka Oscar

Our Mavic Air, FAA # FA3NMEK4RF - aka Oscar!

In looking around, it seemed like DJI was the market leader in the types of drones that we might consider.  Ultimately, we settled on the DJI Mavic Air (in Flame Red, thank you very much!), and we purchased the “More Fly Combo” which included two extra batteries, spare props, prop guards and a carrying case.  We also shelled out for a hardshell carrying case, a landing pad, and some neutral density filters.  Total outlay was just over $1,000, and for that we bring you our Mavic Air (nicknamed Oscar by Victoria who insists that it is the only robot she loves), FAA #FA3NMEK4RF. Which brings us to the next point - flying legally!

Making it Legal

Choosing a drone was fairly easy.  Figuring out how to fly it legally, that was more challenging.  Way back in the day, I was a private pilot, but I found that I either had the time, but no money, or the money, but no time.  And living in the greater LA area meant dealing with the most complicated airspace in the country, if not the world!  So I quit flying when my daughter was born and haven’t flown since.

But, that did give me a leg up in learning how to fly legally, since I was generally familiar with the rules and regulations from the Federal Aviation Administration (FAA).  One of the first things you learn is that any drone that weighs more than 0.55 pounds must be registered.  Our Mavic Air weighs in at just over 15 ounces, so registration was a must.  Turns out that is super easy, and can be done online for a nominal fee.  We had our local label maker create registration labels so our Mavic Air is legal everytime it flies!

Of course, getting me licensed was another matter!  I found a number of great resources online, including this great video created by Tony Northrup! Tony’s video is an hour and forty-three minutes long and I watched it multiple times.  He is clear, funny, and amazingly helpful.  I also found an online study guide (currently unavailable as they update it) here.

The test consists of 60 multiple choice questions and you need a 70% to pass.  While a significant number of the questions are really just common sense - like is the FAA going to ever suggest that having a drink of alcohol will improve your visual acuity??? - there are a number of questions that require you to parse a weather report that looks like this: KIAD 180005Z 19008KT 10SM TS SCT060CB BKN090 BKN200 31/21 A3002 RMK AO2 TSB04 FRQ LTGICCCCG SW TS SW MOV NE T03060211 (seriously!), or puzzle through a sectional chart that is one of the densest data presentations ever invented. (Don’t believe me?  You can download it here, but be patient, it will take a while!)

Suffice it to say, I took my test prep seriously, and the result was rewarding: 100%! 

Now all I needed was to start flying!

Flying for (fun) and Profit!

So now that I was a fully licensed drone pilot, it was time to start putting those skills to use.  Here are some recent drone shots and a description of their application.  (In each case, clicking on the image will give you a full-scale picture.

Completed residential solar installation   

Finished Project Photography

One of the really cool uses for the drone is to give homeowners a view of their new system that you just cannot get any other way!

This image shows a just completed tilt-up system on a flat - and very bright white roof!

Garage roof   

Residential Site Evaluation Photography

Another great reason to use the drone is to take imagery that our friends at Scanifly can turn into a 3-D model - all without actually going on the roof!  This is a 25 degree pitch garage roof - not really something you want to walk on if you don’t have to!  Guess what, thanks to the drone, everyone stayed on the ground and we got a great model to use for our proposal!

Array inspection   

Inspection Photography

The other day, one of our clients reported that a neighbor’s tree had fallen on his carport, where our solar system was installed five years ago.  When we came out, the array was completely buried under the tree.  We advised the client to get the tree removed and we would return to survey the array for damage.

Once again, we were able to examine the array closely for signs of damage, without ever breaking out a ladder!

Commercial building   

Commercial Site Evaluation Photography

One of our most anticipated uses if for modeling larger commercial roofs.  Using Scanifly, we can get shading readings for any area on the roof, letting us have very accurate production models, thereby allowing us to provide our commercial and non-profit clients with better proposals than ever before.  And when you try to distinguish yourself by the quality of the information that you can provide, this is a great leap forward!

We really think that the drone brings us a new level of safety and competence.  So when you call us for that site evaluation, don’t be surprised if we never break out the ladder, but instead let Oscar - the newest member of the Run on Sun team - do the hard work for us!

Building Client Trust - Podcast with Run on Sun Founder & CEO, Jim Jenal

At Run on Sun we work hard to build trust with our potential clients, and to maintain that trust with those who choose to go forward with us.  Recently, our distribution partner, BayWa, r.e. asked Run on Sun Founder and CEO, Jim Jenal, to join a podcast discussing that very issue.  Jim shared the mic with Tom Miller, Creative Director at BayWa, and Pam Cargill, Principal at Chaolysti Interactive, a consulting firm focused on improving the solar industry.

Although Jim was a bit embarrassed by the title - “In Jim We Trust” is a bit much - he stands by the thoughts expressed!  Check it out:

We would love to hear from both clients and other installers alike - how important is it to build trust?  What do you do to achieve that end?  And what happens when that trust is damaged, how do you make things right?

Meet Sara Pavey!

Sara Pavey

Sara multitasking at a job site.

It is with great excitement that we introduce to you the latest member of the Run on Sun family, Sara Pavey, our new Projects Coordinator!

We’ve had our eye on Sara for quite some time as she has been in the solar industry for more than five years with a variety of other solar companies.  Indeed, during her tenure at one of those companies, her bosses derided her as a “teller, not a seller,” because she has the audacity to take the time to fully explain things to potential solar clients!  Needless to say, we are thrilled to have another “teller” on our team as we are fully committed to answering all of our clients questions before they sign on the dotted line!

Sara is a proud graduate of Cal Poly San Luis Obispo (Go Mustangs!), earning her degree in Mechanical Engineering. Sara demonstrated her technical insights at her very first Run on Sun jobsite, suggesting a clever re-routing of cables that was both more efficient and more aesthetically pleasing.  We look forward to putting all of her tech skills to use—as well as her “telling” approach to sales! 

Prior to joining Run on Sun, Sara honed her installation skills by volunteering with Grid Alternatives, a nationwide non-profit that “brings the benefits of solar technology to communities that would not otherwise have access, providing needed savings for families, preparing workers for jobs in the fast-growing solar industry, and helping clean our environment."  (Learn more about Grid Alternatives here.)

A native of Southern California (yes, there really are some natives here!), Sara lives in Pasadena with her husband, Kyle, and two (very) young children, Isla and Liam. When Sara is not crunching numbers or climbing on the roof, you will find her at the LA Zoo, Kidspace Children’s Museum, or a local trail. If both children are miraculously napping at the same time, she likes to paint colorful abstract paintings on any available surface, including the shower door.  (Another skill for us to tap!)

Please join me in welcoming Sara to the Run on Sun family!

Video Release: Making the world better...one roof at a time

Its not every day that we get to unveil a beautifully crafted video showcasing just what it is that makes Run on Sun tick. Happily today is different! Our fabulous distributor, Baywa r.e., has partnered with us to create our very own professional marketing video:

Baywa r.e. has been more than just a products distributor for Run on Sun. We began our partnership with Baywa, formerly Focused Energy, back in 2009 when we found them to be a much more detail oriented operation than their competitors. They proved to us they could translate what happens on the roof to ensuring we got all the pieces necessary to make installations run smoothly. Now, our primary reason for continuing to partner with Baywa r.e. has evolved. Their management and staff all share our vision for a solar industry that is better. One that operates with the highest degree of ethics and transparency and a mission to help consumers save money while reducing our impact on the environment. They have supported us, and other small installers, in many ways far beyond the normal functions of a distributor. Case in point is this video which they produced to help us share our message with our community.

I’d also like to point out a few details on the installations featured in this video: 

LAWC Reservoir

Lincoln Avenue Water Company Reservoir Project: 

This was our second project with Lincoln Avenue after helping their administrative office go solar in 2011. The 2015 Reservoir project was in partnership with Baja Construction building the ground mount structure to support the 246 LG280 watt panels and Enphase M250 microinverters. Run on Sun installed the solar system to utilize otherwise unused land below the reservoir offsetting nearly 50% of the energy required to run their pumphouse.  

Westridge School for Girls:

Westridge School for Girls

While we didn’t end up shooting video at Westridge we really wanted to be sure to include this project as it is near and dear to our hearts. As Run on Sun’s first school installation and Jim Jenal’s (Founder and CEO) daughter’s alma mater we really enjoyed helping them go solar. In 2012 we installed a solar array on their Performing Arts Center consisting of 216 LG250 watt solar panels which were the cream of the crop back then! Working with Westridge School for Girls was a wonderful experience which included our very own Jim Jenal leading a science class tracking a solar eclipse using the Enphase microinverter data! We believe solar at schools offer such great added benefits providing a resource for students to learn about renewable energy as well as math, engineering, environmental issues and more! 

Chandler School Solar Installation

Chandler School:

In the Fall of 2015 we completed the installation of 147 LG300 watt solar panels on the gym at Chandler School. Chandler was also a fantastic partner to work with partially because we share their values in environmental stewardship. We hope that growing up in an educational environment where solar power is the norm will help students navigate a future where sustainable clean solutions will be the only way forward. We would also like to give a huge shout out to the amazing Trevor Spicer, Director of Operations and Information Technology, for the off-the-cuff cameo and kind words in the video. 

Residential 14kW Project:

Residential Installation

This was the most recent Run on Sun installation featured in the video, where a lot of the dialogue with Jim Jenal takes place. This is the second home these particular clients have installed solar with Run on Sun as they recently moved into this beautiful Altadena mid-century modern home. Their roof was a perfect slate for a solar array, and we wouldn’t be surprised if this particular feature was one reason they chose the property! Owning electric vehicles and wanting to offset as much of their electricity as possible we maxed out the space with 44 LG320’s, top of the line panels today! It didn’t hurt that the view from the roof was one to die for, spanning much of the valley with Los Angeles skyscrapers in the distance. Of course, as evidenced by one of the shots in the video, we could also see the smog levels each day we worked at this site further enhancing our resolve to continue to get more solar out there!

Thanks for reading as we share some of the projects we are most proud of. And of course, let us know if you’d like to get a free quote today and share in our commitment towards the belief that the world can be better one roof at a time!

Roofing reality check. Top 3 considerations for solar

So, you are considering a solar power system for your home or business… and why not, given the myriad of social, environmental and economic benefits! But how do you know if your roof is a good candidate? This is one of the top questions to consider carefully before investing in solar. 

Many faces can make layout challenging.1. Do I have enough space?

The size of your solar system is dependent on your usage needs and the amount you want to offset. However, it is not uncommon to find homes and businesses which are “footprint-constrained” - meaning their system size is limited by the space available.

A few things to keep in mind as you look at your roof and ponder how big is big enough… First, while there are many different solar panels they are typically the same size. Run on Sun uses LG panels which are about 65 x 40 inches and can be placed in either a portrait or landscape layout. Panel energy ratings vary, 285-315 watt panels are currently available from LG. For an average home (5 kW) that means you would need around 16-18 panels to offset the bulk of your electricity.

Another limitation is that fire code requires three feet of clear space from all ridges. If you have an irregular shaped roof with many valleys and peaks it may make the layout very challenging. Given that the panels are rectangular and racking is mounted parallel to the roof, rectangular spaces are ideal. However, the 3-foot rule does not apply to uninhabited spaces such as garages and carports making them good options if your home lacks the perfect solar roof. 

Trees can shade your roof and degrade your solar panel output.

 

2. What if my roof is shaded?

Shading from trees, tall buildings, chimneys, or even parapets on flat roofs can significantly degrade the energy output from solar panels. Sometimes all that needs to be done is a generous trimming of that tree that’s gotten a little out of control over the years. Other times it means you really won’t get your money’s worth out of a solar system. But, if the shade elements are few and only during a short time each day, your roof may still be a viable candidate.

If this is the case be sure to talk to your solar contractor about inverters. We have written a great deal about the advantages of “microinverters” in handling shaded roofs, particularly those made by Enphase Energy.  “String inverters” on the other hand would be a bad choice as the entire system would degrade when any single panel is shaded. 

 

3. Should I re-roof my house before adding a solar system?

This may be the most important and frequently overlooked question to consider when researching if solar is right for you. Part of what makes solar a great investment is the 25+ year lifetime of the system. But if you have to re-roof during that time there are added costs to remove and re-install the system. If you are planning to re-roof during the lifetime of your solar array be sure you select components, such as the racking system, from companies that…A. will still be around 15-25 years later, and B. will be able to provide compatible replacement parts when pieces are lost during removal and re-installation. Avoid newer companies testing out “state-of-the-art” racking systems and cheap companies banking on the solar boom alone.

For this reason we always ask owners the age of their roof. In southern California, a roof over ten years old should get a makeover before installing solar. If you are unsure of the condition, it is a good idea to have a professional roofer take a look and give you an expert opinion. Sometimes solar contractors can offer this as part of their free assessment. (Run on Sun works with a very reliable roofer who is happy to take a look at any roof in question!) If the roof still has some life left in it but not enough to outlast the solar system you could re-roof only the area where the solar array will cover and plan to do the rest later. An added benefit is that the solar panels will actually protect your roof from the elements, helping it to last longer.

 

Unfortunately, you will likely be able to find someone willing to put solar on your roof even if it isn’t a good candidate. But if they aren’t discussing the above issues with you, then red flags should be flying! To ensure you get the best investment possible, do your research, take a good long look at your roof, and discuss all of your concerns with your solar contractor.
