If you’re not already installing solar+energy storage for your customers, you soon will be. But which energy storage technology is best? What’s the price per kWh? How long will the battery technology last? Are Lithium-based batteries really the best? How expensive are flow batteries? How about flywheels?

You can ask any of these questions–or anything else–and get an answer from SepiSolar’s CEO and storage expert, Josh Weiner. Also answering your questions will be our special battery technology guest, Matt Harper, Chief Product Officer of Avalon Battery.

Before Avalon, Matt was a former VP of Products and Marketing at Prudent Energy and has 9 years developing energy storage technologies. He holds 7 US patents.

In addition to being CEO of SepiSolar, Josh has been designing solar+storage systems since 2004 and was one of the early co-founders of Green Charge Networks (recently acquired by Engie.). He now consults with developers, as well as various storage manufacturers.

Over the years, Josh and Matt have separately studied many different battery technologies, and they’re both excited to be sharing their objective knowledge and opinions, answering any of your battery technology questions LIVE at the EES stage at Intersolar or on our usual web platform at the same time.

If you’ve never sat down and had a drink with SepiSolar’s CEO Josh Weiner to get to know him, here’s the next best thing: Listen to his 3-Part Suncast podcast interview with host Nico Johnson.

Nico’s intimate weekly podcast has interviewed solar luminaries such as Jigar Shah, Dan Shugar, and Stephen Lacey, so Josh was honored to be invited to be another guest on Nico’s show.

Josh and Nico didn’t exactly have a beer together, but they talked as if they did. They not only discussed solar and energy storage best design practices, but also about the influences in Josh’s life growing up and his vision for the solar+storage future. They talked so long that Nico had to break up the interview into three parts.

All three Suncast episodes are embedded below. You can also subscribe to Suncast on ItunesStitcher, or your favorite streaming service.

Here’s a rundown of what Josh and Nico discussed:

Episode 81: Tactical Tuesday with Josh Weiner

Episode 88: Battery Net Metering Changes Everything

  • SepiSolar’s foundation story and what separates them from others
  • Lessons learned from Akeena Solar’s IPO and dramatic growth
  • The not-so-strange connection between Music & the Solar Industry?
  • The incredible impact a neighbor can have on a young mind

Episode 89: How a Downed Boeing Dreamliner and a NY 7/11 Store Influenced the Solar Industry

  • How a 7/11 in New York became the pivot point for the storage industry
  • How a downed Boeing Dreamliner changed Josh’s career trajectory
  • A clear case for including energy storage in the solar Investment Tax Credit
  • According to Nico, one of the best answers to his Crystal Ball question in the history of SunCast

SepiSolar’s CEO Josh Weiner was recently interviewed by David Brearley in SolarPro Magazine’s In-House versus Outsourcing Solar Engineering Services in the May/June 2018 issues.

Not every solar company needs to be outsourcing solar engineering and design, but Josh comments on why quality design firms can be the most efficient and cost-effective solar service solutions for many solar contractors, developers, and EPCs.

SepiSolar engineers aren’t just NABCEP solar+storage design experts, they’re also requirements experts, producing designs that meet the detailed requirements of of any AHJ or utility across the U.S.

If you missed our first Ask SepiSolar Anything with SepiSolar’s CEO Josh Weiner answering solar+energy storage questions, you can’t ask any more questions, but you can listen to the whole session here:

Josh tackled some great questions from people tuning in to this live and interactive program:

  1. What are some of the common KW inverter sizes for C&I solar+storage? (at 11:12)
  2. When you’re doing solar PV plus storage, what kind of interconnection requirements, like 120 percent rule, do people face? Are you seeing more AC or DC coupling on the system? (at 13:20).
  3. For commercial solar+storage, who are the customers that would benefit the most from solar+storage, and who are the customers that aren’t yet ready? (at 20:40)
  4. What type of energy storage is available and viable for the Florida residential and commercial market? Which brands? Also, does storage benefit from the 30% ITC credit if installed in conjunction with solar? (at 26:00)
  5. For O&M requirements for lithium-ion batteries for C&I solar+storage applications, is there maintenance required on a yearly basis? Or is it bi-yearly? What kind of components need to be serviced? What kind need to be replaced? (at 30:15)
  6. Is there an unbiased accurate chart from an independent testing lab of expected life cycles of all that all the battery brands? (Short answer, yes, but there’s only one that’s public.) (at 38:02)
  7. How does energy solar PV and energy storage work with virtual net metering and aggregate net metering? (at 43:22)
  8. What is the unit based cost for battery O&M? (at 47:10)

As California energy storage becomes more widespread, utilities have been concerned about battery owners charging their systems from the grid at a lower price and then selling that same utility power back to the utility at a higher price and receive net energy metering (NEM) credit.

To address this important policy issue, our CEO Josh Weiner has been working with the California Solar and Storage Association (CALSSA) and our client NEXTracker to suggest a technical firmware solution for inverters that would prevent batteries from charging from the grid, thus allowing DC-coupled PV plus storage systems to participate in utility NEM programs.

We’re proud to say that Josh’s technical firmware solution has been embraced by both CALSSA and the utilities and appears to be on its way to being approved by the California Public Utilities Commission. (CPUC).

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.
