Solar Energy Show

Will the future of energy be driven by massive utility solar farms or millions of local rooftop systems? John Farrell from the Institute for Local Self-Reliance shares his insights on how utility monopolies are strangling local solar efforts -- especially in California -- where monopoly utilities are locking customers into sky-high rates. The conversation delves into the growing trend of “grid defection” as consumers use their own solar and battery systems to reduce their dependence on utility power. With an appropriately sized solar and battery system -- with a little help from a friendly EV -- it is indeed possible to cut the cord with the utility completely. Locations with lots of sunlight and high electric rates will be the first places where people can cost effectively ditch their local utility. With all due respect to Alice’s Restaurant…could this be the start of a nationwide movement? Please tune into this week’s Energy Show episode at www.energyshow.biz.

Nuclear power will make electricity too cheap to meter,” a prediction made in a 1954 statement from the head of the Atomic Energy Commission. 70 years later I’m predicting that electricity will be almost free, but powered from that fusion generator 93 million miles away. Sounds crazy, but rooftop solar is already generating power for $0.06/kwh — compared to our average rates here in California of $0.45/kwh. As rooftop solar costs continue to decline and grid electricity costs continue to increase, we need to prepare for three traumatic energy industry changes: 1. Gasoline demand will plummet as EVs dominate road transportation. 2. Natural gas demand will decline steadily as heat pumps dominate space heating and solar dominates power generation. 3. The utility business model will collapse as technological changes (solar and batteries) turn the electric grid upside down. Please tune into this week’s Energy Show as we dive into the capital costs, operating costs, ownership arrangements and timing for the four

Anyone who pays an electric bill in California knows we’re in the midst of an energy crisis. The stark reality is that this crisis is enabled by politicians who lack the will to do something about it. But unlike many politicians, Sam Liccardo took action to lower electric bills when he was the Mayor of San Jose. Now, as candidate for U.S. Congress, Sam plans to tackle this these energy affordability problems on both a state level and national scale. Please join me on this week’s Energy Show as U.S. Congress candidate Sam Liccardo talks about his work on safer bike lanes, how a heat pump keeps his house cool, and of course affordable energy. Perhaps most important — how his "across the aisle" political philosophy will help him get things done in Washington, DC. Looking for real-world solutions to sky-high energy costs?

FINALLY, someone who actually understands our crazy-complicated electric bills! His name is Dr. Ahmad Faruqui. I’m delighted to have Ahmad join me on this week’s Energy Show to talk about energy policy -- with a particular focus on why the heck our electric bills keep going up when it’s so inexpensive to generate power with solar and wind. It helps to have a PhD in economics, as Ahmad has from UC Davis. He started his energy policy career at the California Energy Commission, and then went over to the Dark Side at EPRI, the Electric Power Research Institute, after which he worked at the Brattle Group on energy consumer policies. So he understands the economic theories as well as the realities of the electric utility industry. New energy technologies, such as rooftop solar and batteries, have disrupted the 120-year old utility industry. Please tune into this week's energy show at www.energyshow.biz for an expert’s view on how these technologies should best be deployed to provide affordable and reliable elect

California’s clean energy future is on a collision course with profit-oriented monopoly utilities. From the Governor’s office to the California Public Utilities Commission to the Legislature, policies are being implemented that are leading to skyrocketing electric rates and record utility profits — while at the same time crushing California's rooftop solar and storage industry and knocking the state off track in meeting its own clean energy goals. It’s a classic David vs. Goliath story. Only, instead of “David” being one person standing up to the powerful utilities, given the unique power of solar energy, here, it is every ratepayer, every solar worker, every solar business fighting to protect the right for consumers to generate energy from the sun. And Bernadette Del Chiaro, as the Executive Director of the California Solar and Storage Association (CALSSA), is leading the fight for affordable, safe and reliable power for homes and businesses.

I bet you didn’t know that the “WH” in FranklinWH stands for "Whole Home." The Jersey Boys from Franklin designed their battery system from the ground up to help people back up their whole home without adding extra batteries or expensive load shedding subpanels. This capability has made Franklin one of the best selling battery systems on the market. Founder Gary Lam and Product Manager Doug Amarhanow — both Rutgers graduates — are my guests on this week’s Energy Show. In addition to integrated load shedding, the FranlinWH system also allows homeowners to expand their rooftop solar systems without triggering the Net Billing Tariff (or NEM3). On the near-term horizon is a capability that will allow EVs with a 240 volt generator output (such as the Ford Lightning and Tesla Cybertruck) to power a home independent of the grid. To learn more about these unique Whole Home backup features from FranklinWH, please tune into this week's energy show at www.energyshow.biz.

“SunPower” and “bankruptcy” are two words I never thought I’d see in the same sentence. But we should temper our schadenfreude. The solar industry owes SunPower and their employees tremendous gratitude. Without a doubt, our industry would be much smaller without SunPower’s early and determined leadership. So rather than dance on their potential grave, this week’s Energy Show will focus on SunPower’s accomplishments that I’ve witnessed first-hand over the past 20 years. Think about back contact cells; best dealer network; utility-scale installations on five continents; horsepower behind CALSSA and SEIA; Million Solar Roofs; uncapped ITC; Swanson, Werner, Shugar, Wenger, Blunden, Starrs; NexTracker and Renova. The list goes on. There’s plenty of news about SunPower’s demise. For the other side of the story, please tune into this week’s Energy Show at www.energyshow.biz.

Who would have thunk that you could put a 240 volt split phase inverter on the back of every solar panel? The gurus at Enphase and Akeena did, and I've been a fan ever since their first prototypes in 2008. In fact, I still have Enphase M-190 microinverters on my San Francisco home. Time for an upgrade? Probably! Our special guest is Raghu Belur, co-founder and Chief Product Officer of Enphase. We've discussed microinverters for 16 years, witnessing Enphase's rise in the solar industry. Raghu shares insights on their product lineup, market segments, manufacturing hubs, and how they're leveraging IRA incentives. We explore open vs. closed home energy ecosystems, and the integration of battery, inverter, software, and EV charging technologies. We also cover whole home backup designs, industry challenges, and Enphase's influence on energy policies.

You don’t have to be a Boomer to remember the days of simple DC wire connections to string inverters. For the most part, these times are long gone. Since 2010, module-level power electronics (MLPE) have taken over — and now, with batteries and advanced load control, solar systems have evolved into the energy focal point for homes. This Energy Show podcast highlights new capabilities from SolarEdge, broken up into two segments. Today’s podcast, the first SolarEdge segment, is focused on interests and needs for homeowners. We saved the geekier deep dive for installers in the second segment, which will be released in a few weeks. Joining us on these two SolarEdge podcast segments are Bertrand Vandeweile, SolarEdge’s new GM for North America, and John Ahlman, their Chief Marketing Officer. We dive into the benefits of optimized string inverters, batteries, and load control of multiple home devices. Discover why homeowners should care about lifetime system “energy harvest,” as well as the tradeoffs between open

Yes, definitely. Heat pumps are literally and figuratively cool. And without a doubt, the best time to consider installing a heat pump is when your AC (or furnace) dies. Heat pumps do double duty, providing both heating and cooling. They offer significant savings and improved comfort -- which I confirmed first hand after my old outdoor air conditioner compressor died. Replacing both my old AC and gas furnace with a heat pump was one of the best home improvements I’ve ever made. The system operates almost silently, has better temperature control throughout my house, and my heating and cooling bills are down significantly. New heat pump models use inverter-based variable speed compressors with efficiencies in excess of 350%. These high system efficiencies mean that your total heating and cooling costs will almost always be lower with a heat pump than an ordinary AC and gas furnace. And from a comfort standpoint, with mini-split models you can even heat/cool individual rooms in your house! Sure, a basic AC re

Consider the poor photons! If your panels are dirty you are causing trillions of premature photonic deaths when they collide with dirt molecules. Please give those photons the chance to knock an electron loose from an eager semi-conductor. Instead of being converted to heat and banished to quantum hell. Save The Photons. Clean Your Solar Panels After just a week, your panels might look slightly dusty. But a light coating of dust doesn’t significantly block sunlight. However, severe grime, especially on low-tilt panels, can slash your output by over 25%! You can’t save all the photons all the time, but by watching your solar monitoring system you can tell mathematically — as well as visually — when your panels should be cleaned. If you have a larger system in an area with high electric rates and a dry climate, the economics of cleaning become more favorable. When it comes to cleaning solar panels there’s lots of bad advice on the internet…and even from manufacturers. On this week’s podcast we address WHEN

Are you sick of all the heat pump hype? Skeptical about why you should buy one right away? Don’t mind paying huge bills to your utility for methane (natural gas)? Even heat pump enthusiasts like us agree with you — they are definitely NOT for everyone. Here are five reasons why heat pumps may not be the right thing for your house: 1. You don’t believe in global warming and prefer to burn fossil fuels 2. Heat pumps are too expensive 3. It's too complicated to install a HPWH or HP HVAC 4. You rent your house or plan to move 5. Your existing HVAC and water heater works fine With all the tax credits, rebates and financing options, heat pumps are more affordable than ever. They deliver significant energy savings, offer better comfort and provide superior indoor air quality — even for complicated installations. With efficiencies over 300%, heat pumps are almost always less expensive to operate over the long term, and can be installed in almost all existing homes. On the other hand, from an economic standpoint it

This week's Energy Show dives into the tumultuous landscape of the clean energy industry, painting a picture of contrasting fortunes akin to the classic “Tale of Two Cities.” On one hand, we witness a surge in demand for clean energy, driven by improving economics, lower equipment costs, and rising electric rates, alongside enticing incentives. Yet, on the flip side, California experiences its first-ever decline in rooftop solar installations, coupled with a slowdown in electric vehicle growth and a resurgence of incumbent fossil fuel companies. Amidst this dichotomy, our guest, Jon Semingson, President of Peak Demand, Inc., sheds light on the critical challenges plaguing the industry's infrastructure and human resources. From a scarcity of skilled construction labor to a dearth of executive-level talent, the hurdles to industry growth loom large. Moreover, financing remains a linchpin, with uncertainties surrounding tax equity and interest rate trends. The urgency of these issues is underscored by the gr

I read an avalanche of media criticism when Elon Musk fired his entire SuperCharger team a few weeks ago. In spite of all the whining, it was a good business decision for Tesla. Here’s why: expanding and running a fast charging network is a lousy business. Installation costs are high, permitting and construction delays are extensive, and revenues from charging cannot overcome the high electricity costs charged by utilities. According to a McKinsey and Company study in October of 2023, most EV fast charging sites are swimming in red ink, losing $45,000 a year at every 4 port charging station. A back-of-the-envelope calculation shows that a typical Starbucks in California would have to sell 56,000 extra cups of coffee every year just to break even on EV charging. That’s a lotta Joe. In spite of complaints about high gasoline prices, gasoline is a worldwide commodity with reasonable substitutes. Prices are set by the free market. But prices for electricity supplied to charging stations are set by utilities wh

10 years in the solar and storage industry qualifies most industry veterans as a solar old timer. But there is one person who stands out as a beacon of leadership, longevity and success. Ed Murray has been heating water molecules (solar thermal), converting photons to electrons (solar PV) and saving customers money since 1978. That’s 322 dog years! Ed Murray, CEO of Aztec Solar in Sacramento, knows solar thermal, PV and storage technology like the back of his hand. He’s managed to run his successful solar business in spite of the “solar coaster” craziness. But what impresses me the most about Ed is his industry leadership. Ed has been on the Board of Directors of the California Solar and Storage Association for 40 years, has been serving as its president since 2016, has been on the Board of the North American Board of Certified Energy Practitioners for 14 years, and served on the Board of the Solar Energy Industries Association for 14 years.
