This live interview was facilitated by Josh Weiner, Solar Expert Witness & Solar Engineering Expert. Mr. Weiner has been at the forefront of the solar energy industry for over 20 years and is an industry leader on solar-plus-storage engineering & design. Josh’s expertise spans both in-front of and behind-the-meter initiatives including residential, commercial, utility, grid-scale, and ev charging solar and storage applications. 

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.
