Velvet Dallesandro - Electrician and Solar Jedi Master

I love conducting solar site assessments and having that first conversation with a potential client. Often we spend far more time discussing all the ins and outs of going solar with the property owner than is necessary for the solar assessment measurements. One of the questions we always spend some time on is: “How exactly is Run on Sun different than other solar companies?” Here in sunny Southern California this is an important question as there are so many people offering PV solar services. Of course I describe how the products we use are selected for their high quality, warranties, and trust in the manufacturers. I also explain how as a small company with a mission focus, we take a very honest and ethical approach to helping people green their energy. But one of the major ways we stand above all the rest is also a feature that is hard to convey in that first conversation. Hence, the theme of this blog post…

My best answer to the above question, “We have Velvet Dallesandro as our Chief Electrician.”

The work that Velvet does connecting the power of the sun to your electric meter is akin to an art form. But alas, the art of a solar electrician is often hidden behind dead plates and easy to overlook if you’re not paying attention. So here are a few examples of Velvet’s work. She may not be in a Los Angeles art gallery but her work is providing people with beautiful, safe, and emission-free energy across the county! 

 

Service panel

Disconnect

If you’ve ever looked behind the dead plate on your electric bus (where all your breakers are) you likely were frightened by what you saw. A mess of cables, cobwebs, and sometimes outright dangerous circumstances - like the time I saw one missing its main breaker entirely. However, if Velvet is re-wiring your service panel it may look more like something you could put on your wall with rainbows of color coded wires and perfect 90 degree bends. (Service panel shown at left by Velvet, solar AC disconnect work at right by Ralph Carillo.)

Chandler Conduit 

Wiring is far from Velvet’s only art form. How do installers bring solar power from the roof to the electrical service? While the most visually appealing is to hide the magic completely by going thru an attic space and inside walls but sometimes that just isn’t possible. 

conduit

Velvet doesn’t just throw flex conduit around willy nilly to get the job done quick like some installers. It takes a lot of creativity to make the wiring run as attractive as possible. First and foremost, she always uses galvanized conduit for outside wiring as opposed to flex - it lasts for the long run and it is much more difficult to punch a fire axe through than flex, making it much safer. Second, Velvet avoids piecing together conduit as much as possible. Her goal is to make whatever crazy runs are necessary as seamless as possible - think avoiding possible leaky weak spots at seams. This means she has become a jedi master at bending conduit. Eight bends in one stick of conduit paralleling windows, gutters, or that pretty bush you don’t want to disturb? Not out of the question when Velvet is on the job (or her prodigy apprentice Ralph for that matter). 

 

Beyond the art she’s also an all around rock star. Check out this classic; pulling wire for a 45kW job at Chandler School…(That’s her on the right pulling wire through at least 30 feet of conduit on a 100+ degree summer day.)

Pulling her weight

She more than pulls her weight! So if you’re looking into going solar take note, there is an art that goes into the details. And the details really do count! Velvet’s wiring is the safest you will find and truly built to last. A rarity in an industry where most companies are trying to race through projects at lightning speed. Bottom line…we are so thankful to have Velvet on our team!

2016 Top 500 Solar Contractors: Still on Top!

Solar Power World Top 500 ContractorsIt’s the time of year again when we hold our breath and hope to be included in the Solar Power World Top 500 Solar Contractors list. As more and more companies come into the solar sector it becomes more and more of a real honor to be included in this prestigious list of the best in the industry.

Run on Sun made the cut!

We’d like to thank our friends at Solar Power World for the valuable work they do delivering well-rounded information on the solar industry to the wider public. They also provide a very important service helping our solar community to share information, best practices, and continue to thrive and grow. This is our fourth year running on the list which has been published for the last five years.

Beyond the Top 500 list, Solar Power World also gathered some data about the industry as a whole through their annual survey. Some interesting facts from the results include:

  • Solar continues to provide valuable jobs: Top Solar Contractors employed 133,707 people in 2015, up from 124,967 in 2014.
  • Residential markets provide most solar jobs: 287 contractors worked primarily in the residential market; 154 worked primarily in the commercial market
  • California continues to lead: 130 companies were headquartered in California
  • Many companies are investing in rigorous solar education: 355 companies had at least one NABCEP-certified principal on staff. (Run on Sun is proud to have all principals NABCEP certified)
  • Most solar companies are local businesses: 77% of companies reported doing most of their business within its state of headquarters
  • Many solar companies are small businesses! 119 contractors reported have 10 or fewer employees; 236 reported having between 11 and 50

While the majority of solar electricity is produced at large utility-scale solar power plants, the majority of jobs are actually located with local small to medium sized companies that service residential and commercial clients. 

“No one can deny that local companies are supporting the growth of the industry. Our Top Solar Contractors are the face of the industry—meeting homeowners and business leaders on doorsteps every day.” - Kathie Zipp, Managing Editor Solar Power World

When you support solar, you not only benefit the environment but with many solar contractors you are also supporting small local businesses that provide jobs and put money back into our local economies. It’s nice to know Run on Sun is in good company and that we have great people like the team at Solar Power World backing our efforts to build a clean-energy future for all. Congratulations to all the top 500 solar contractors of 2016!

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!

Power, Energy, & kiloWhat?? Solar Terminology 102

 Click here if you missed Solar Terminology 101: The Wonderful Magic of Electricity.

What Exactly is a Solar Power System? 

Solar array

Now that you have the electrical basics down, let’s talk solar. The following are common terms a solar contractor may use when discussing your solar system. By understanding the “Greek” you will be in a better position to make sure your contractor knows what they’re talking about…and its kindof fun to understand the miracle that is solar power!

 


Solar Energy
— Electromagnetic energy transmitted from the sun (solar radiation). 

Photovoltaic (PV) – The direct conversion of light into electricity. Photo means “light”, and voltaic means “electric”.

Solar (PV) Cell — The smallest semiconductor element within a PV module which converts light (photons) into electricity. Also called a solar cell.

Solar panelSolar (PV) Module — Also referred to as a solar panel, an integrated electronic device consisting of multiple Solar Cells, arranged in an interconnected grid, encapsulated against moisture and other environmental agents,and held together by a rigid frame for mounting. A typical PV module that we use is roughly 65 inches by 40 inches and contains 60 cells. 

Solar (PV) Array — An interconnected collection of PV modules that function as a single electricity-producing unit. The modules are assembled with common support or mounting, common pitch and azimuth (direction). 

Solar (PV) System — A complete set of components for converting sunlight into electricity by the photovoltaic process, including the array and balance of system components (e.g., switches, subpanels, etc.).

Grid-Tied - A grid-connected solar electric system generates its own electricity and feeds its excess power into the utility grid for later use. Grid-tied solar electric systems are eligible for incentives and rebates as opposed to “off-grid” systems which are not.

Net-Metering - Net metering is a billing arrangement between a solar customer and their utility which allows the solar system to send excess electricity back to the grid through the customer’s electric meter. The meter actually runs backwards! Your utility then bills you for the net (kWh used – kWh generated). While most utilities will pay you a small rate if you generate more than you use, many opt to carry forward a credit toward your next bill.

 

 Solar Power to Run your Life

The next set of terms describe the way we convert the energy coming into the solar cell from the sun into a form that you can use to power your everyday electronics…


How does solar workDirect current (DC) — Direct current refers to power that never changes polarity. DC power flows in one direction through the conductor. To be used for typical 120 volt or 220 volt household appliances, DC output such as from a solar panel or battery must be converted to alternating current.

Alternating current (AC) — Alternating current refers to power that constantly changes polarity between positive and negative over time. Power produced in the United States moves in current that changes polarity at a rate of 60 times per second. Electricity transmission networks use AC because voltage can be “stepped-up” to high voltage (for long-distance transmission) or “stepped-down” to low voltage (for local distribution) with relative ease. This is the current that your household devices use.

Inverter- An electronic device that converts DC power from solar modules into AC power for using in your home and feeding back to the grid.

String Inverters – A string inverter is designed to handle multiple strings of solar  modules wired together in series. These are the oldest type of inverter for residential and small commercial PV systems.  

Enphase microinverterMicroinverters- A Microinverter (like the Enphase inverter to the right) is an inverter designed to handle small amounts of power and is paired with each solar module. They provide many advantages over string inverters such as eliminating a single point of failure, individual module monitoring, and avoiding string degradation from minor shading.

Central Inverters – These are only used to handle very large PV systems, 1 MegaWatt or more, often only in the largest utility-owned solar power systems.
