SepiSolar’s Josh Weiner was recently interviewed about trends in solar+storage design and engineering by Barry Cinnamon on “The Energy Show,” a radio program on KDOW Radio AM in San Jose California, as well as a popular solar industry podcast.

Josh and Barry have a long solar and storage relationship together going back to when Josh was leading Barry’s engineering department at Akeena Solar, the first national solar installation company. Their lively conversation talks about solar and storage trends, which includes a conversation about some new and improved alternatives to Lithium Ion-based storage systems.

My fellow solar designers and engineers, make no mistake: We have been and will continue to be an important part of the world’s transition from fossil-fuel-based energy to a world that will be powered by interconnected and networked solar, wind, storage and integrated micro-grids. For those of you who don’t know what you’re getting into, welcome to the renewable revolution and hold on; it’ll be a bumpy ride! For those of you who already know the solar coaster, congratulations and thanks for your contributions! But … our contributions are far from over.

Energy analysts say that our full transition is inevitable, and that clean energy destiny can be accelerated by innovation, efficiency and improved designs, or just as easily decelerated by flawed, fossil-fuel biased or outdated policies, soft costs and careless designs that lead to bad publicity and damaged customers.

My fellow technical subject matter experts, you and I both know that such a transition is impossible without the minds and efforts of professionals like us doing our part. The sort of work we do is based on sound and well-understood scientific principles of math, engineering and technology.

Having studied these materials for quite some time, we know the power they can bring, as well as our responsibility to accelerate them—we are in a unique position to leverage these principles and the tools our industry has developed in order to make them ubiquitous and accessible to all through more streamlined and easy-to-use products and services.

Newton’s first law of physics states: “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” Similarly, I would say that the U.S. is transitioning toward 100% renewable energy at the same speed and direction that, while positive in direction, is not moving at a speed that will mitigate the worst effects of climate change, let alone pollution and its health effects.

Consequently, we need an unbalanced force to accelerate that transition, and my fellow solar designers and engineers, that unbalanced force can be you and me. We have the technical ability to accelerate solar + storage adoption and reduce its costs through better and more efficient designs, advocating for better policies, and combining our engineering thoughts. The more we can share best practices, surface the sometimes-nuanced and subtle policy roadblocks that slow our work, and educate policymakers and AHJs throughout the U.S. who are just beginning to see an interest in solar and storage, the faster solar and storage will be deployed and make a difference.

In short, engineers and designers must do our part and lead with our ideas and technical abilities, as well as contribute ideas to changing codes and standards. (Wouldn’t it be nice to one day actually have a truly national solar code?)

It’s for this reason we’re rededicating this SepiSolar blog to sharing solar and storage design and engineering best practices. We also know that this must be a collective effort, so we are opening our blog forum to any solar designer or engineer who also wants to share best practices and thought leadership toward our energy transition.

To contribute your thoughts, please email your posts to [email protected]. As long as it’s useful information (under 1000 words plus any related images, please) that helps to forward thought leadership on design, engineering or permitting for solar, energy storage or the grid, we’d love to publish it here, as well as share it on our social networks and email list. You’ll be fully credited—regardless of which company you happen to work for. From our perspective, solar designers and engineers are not competing against each other, we are competing against fossil fuels, dirty energy, apathy and current policies that stagnate our industry’s growth.

Thank you in advance for contributing, and we look forward to more solar design and engineering leadership.

Josh Weiner is CEO and Founder of SepiSolar

Veteran solar marketer aims to streamline permitting and utility interconnection through more

effective communications about solar + storage design and engineering

FREMONT, Calif.–¬ February 05, 2018 – Noted solar marketing and communications thought leader Tor “Solar Fred” Valenza has joined SepiSolar, a national design and engineering firm specializing in solar, energy storage and solar micro-grids, as its director of marketing. Valenza will focus on promoting SepiSolar’s efforts to streamline solar, storage and micro-grid permitting through more effective communications and collaboration with contractors, utility companies, and local permitting departments.

“Nothing is more frustrating to solar and energy storage contractors and owners than needlessly delayed permitting and interconnection,” said Valenza. “The way to streamline permitting is more effective communications about best practices for contractors as well as the Authorities Having Jurisdiction (AHJ). I joined SepiSolar because it’s genuinely dedicated to building a community of solar designers and engineers who want to get design plans approved and interconnected faster and with less hassle. To do that, we’ll be creating educational content and streamlined design processes that help everyone understand the requirements and design best practices.”

Valenza joins a growing team of full-time solar and storage designers and engineers led by SepiSolar’s CEO Joshua Weiner, who began his career at Akeena Solar in 2006 and went on to consult with Green Charge Networks and direct the engineering department of NRG Home. He founded SepiSolar in 2008, providing design and engineering services to solar developers, EPCs, owner-operators, residential contractors, policymakers, and energy storage companies.

“We’re very excited to have Tor on board at SepiSolar,” said Weiner. “As solar and storage expand across the U.S., designers and engineers need to become better communicators and collaborators with contractors and the AHJs, especially as new storage technologies and micro-grids become more popular. Tor’s solar marketing and public relations experience will allow us to share valuable information that will enable solar and energy storage contractors and developers to expedite the permitting process, reducing interconnection delays and soft costs.”

“Now that storage systems are here to stay, Tor and the SepiSolar team will work hard to advocate for solar + storage-friendly policies with local utilities; participate on technical code committees; and continue to monitor, track, and aggregate all requirements necessary to get these types of systems installed and interconnected, all on behalf of our great customers,” he added.

Valenza is a longtime solar marketer who has provided marketing services to tier-one solar brands since 2008. Prior to joining SepiSolar, he was CMO of Solar at the cleantech public relations agency Impress Labs, which recently merged to become Kiterocket, where he served as senior strategy advisor. He’s also known for his solar marketing and advocacy blogs in various solar publications and for his semiannual Tweetups at Intersolar North America and Solar Power International. Valenza is sometimes known as “Solar Fred,” due to his @SolarFred Twitter handle, where he comments and shares the day’s solar industry news with over 16,000 followers.
