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. For a detailed dive into what it takes to be successful in the s

It’s not a flippant comment or a classic jazz solo — but an existential question about the devastating trend our civilization is on due to climate change. The history of Earth Day shows how the worldwide environmental movement has evolved from concerns about in-your-face air and water pollution … to a focus on the invisible hazard of rising CO2 emissions. To a large degree we’ve cleaned up the worst of the visible air pollution, contaminated water, and toxic wastes hiding under a few feet of topsoil. In the first few decades of Earth Day, consumers, companies and governments were all pulling in the same direction to right these environmental wrongs. But something insidious happened due to the profits that can be reaped by polluting the Earth. Economists call it a Negative Externality (the imposition of a cost to one group of people as an indirect effect of the actions of another group of people). To fossil fuel companies, the negative externality they cause by producing oil and gas — which when burned poll

Welcome back to Part 2 of our interview with Scott Sullivan, my friend and one of the best networked executives in the industry. Earthquake excitement has diminished in the New Jersey area, but seismic changes in solar continue around the country. In Part 1 we discussed what happens in the solar and storage industry — really every industry — when company profits decline. It’s a tough adjustment to make, and many companies have not yet recovered from this high interest rate environment. Nevertheless, the majority of companies have figured out the formula, and the topics that Scott and I discussed are summarized below: * What are the characteristics of a great solar and storage contractor? * What should potential customers look for in a contractor? * Have you seen any changes with the solar panels offered by contractors? * Have you seen any changes with the inverters and batteries offered by contractors? * Is solar financing recovering yet from high interest rates? * Are Virtual Power Plants (VPP) and

Seismic changes in the solar and storage industry? Who would have thought that our friends in New Jersey would relate so viscerally? Their recent 4.8 magnitude quake in early April literally extended this metaphor across the country. Metaphors aside, the solar and storage industry is changing faster now than I have ever seen: * Electric rates are soaring, along with utility profits * Solar equipment costs — panels, inverters, batteries — are declining * UL-3741 standards for rapid shutdown throw a monkey wrench into rooftop safety standards * Demand for electricity to power our EVs and heat pumps is increasing * AI is recently on the scene as the newest electricity demand wildcard * Continued high interest rates are suppressing solar and storage financing * Utilities have wised-up to rooftop solar and storage threats to their profits * Hostile utility policies and relatively high interest rates squeeze installer margins, forcing many unprofitable solar companies out of business * Some companies have cracked

March isn't just about shamrocks and leprechauns; it's also Women's History Month, highlighting the incredible contributions of women in various fields. But have you ever wondered about their role in the energy transition? In general, women are just as involved as men — not just in solar, but also in batteries, hydrogen, policy-making, electrification, and manufacturing. However, there's a glaring gap in representation when it comes to the construction side of energy systems. But not at Luminalt Solar under the leadership of Jeanine Cotter, their President and CEO. Luminalt is the leading solar and battery contractor in San Francisco. One would think that it would be easy to be a solar and storage contractor in a liberal city such as San Francisco. Until you try to find a space to park your van. Or navigate the city’s convoluted permitting issues. Or just try to find a place for a battery and inverter near the electric meter. In our candid conversion, Jeanine and I discuss her journey as she built a succes

The Learning Curve for understanding home batteries and solar systems is steep. Your battery system education will require mastering at least twice as much jargon, TLAs (that’s Three Letter Acronyms), specifications and industry gossip than ordinary solar systems. So if you don’t want to get bamboozled by an aggressive salesperson, this week’s podcast is a great place to start. Some of the topics and questions include: * What is the best way for me to expand my existing solar system? * What are the important assumptions -- such as shading, battery location and equipment compatibility — that I should verify with my salesperson? * How long will my battery last during a blackout? Can my backup battery start large equipment, such as my AC or pool pumps? * What’s the difference between AC- and DC-coupled battery systems, and why should I care? * What changes do I need t make to add a battery to my existing solar system? * What are the building code and fire code restrictions on battery installations in my c

The Utility Empire is striking back. As a result, the rooftop solar industry is experiencing its first decline in growth ever. In California alone the end of Net Metering has resulted in an 80% drop in rooftop installations and 17,000 job losses among passionate Rebel solar installers. Utilities in other states are following California’s lead, leveraging their Death Star-caliber monopoly powers and millions in lobbying money to further reduce competition. Even though we need rooftop solar more than ever, this solar industry decline may leave both new and existing customers in the lurch. New solar and battery customers have fewer, although some will say better, choices. And people with existing systems may find that their original installer is no longer around to support their system. Jedi Geoff Greenfield from Kokosing Solar joins us on this week’s Energy Show. His suggestions will help both new and existing customers continue to benefit from money-saving solar and storage systems. He points out that there

This week we’re talking about World Domination. Domination of energy production, that is. In the re-scrambled words of the wise and infamous Dr. Evil: “Why make Gigawatts when we can make…Terrawatts!” Indeed, solar is on track to completely dominate electricity generation. Solar is growing faster than wind, nuclear and LNG ever did. Alternatives to solar such as nuclear fission, nuclear fusion, CO2 capture and sequestration (CCS), and CO2 direct air capture (DAC) are way too expensive and very slow to scale to meet our needs. And with batteries sited with solar, we’ve solved the problems of intermittency and power when the sun is down. Costs for rooftop solar and storage are continuing to decline as manufacturing scale increases. According to the National Renewable Energy Lab (NREL), rooftop solar can meet 45% of our energy needs. The rest can be easily met with utility scale solar. So as long as we aggressively pursue deployments of BOTH rooftop and utility solar and storage, there is no doubt in my mind

If you’re thinking about solar there’s something important you should know. It should be obvious, but just in case: there is no such thing as Free Solar. Getting solar — or a battery -- installed on your house is not cheap and certainly not free. These projects are significant construction and electrical improvements. No company will install solar or a battery for free. I guarantee it. The Romans had a term for it: Caveat Emptor. Let The Buyer Beware. Unfortunately, disreputable companies still advertise Free Solar. I see these ads on the internet every day. Many states, including California, have laws against this type of false advertising. Nevertheless, these deceptive sales tactics persist. The U.S. Department of Energy advises people to watch out for “too good to be true” offers. Beware of hard-sell attempts to collect your personal data in exchange for a free solar or battery quote. Make sure the contractor you select has the proper installation and sales licenses. If you find yourself a victim of a
