Abstract:
As part of the SEIN Round 3 program, a diverse group of energy stakeholders in Texas set out to develop and pilot new pathways to increase rooftop solar adoption at no upfront cost to low income households. One potentially promising pathway we identified involved combining funding from existing utility and federal programs promoting weatherization and energy efficiency. Our objective was to demonstrate pilot projects that equitably deployed rooftop solar to properties owned or rented by families in disadvantaged communities. Our goal was to create a clear path for low income households to achieve electricity bill relief and to access clean energy by leveraging existing utility energy efficiency programs with existing federal resources, such as the U.S. Department of Health and Human Services (HHS) Low-Income Home Energy Assistance Program (LIHEAP) and/or U.S. Department of Energy (DOE) Weatherization Assistance Program (WAP) funding in Texas. This has been attempted in a few other states with varying degrees of success, but not yet in Texas.

Dallas Should Adopt Department of Energy App to Speed Solar Permitting.
TXSES Executive Director Patrice “Pete” Parsons co-wrote this excellent article published in The Dallas Morning News with Ian Seamans of Environment Texas.
Power outages affecting 325,000 people in southeast Texas and 650,000 in North Texas at the end of May were a further reminder, if we needed one, that major changes to our grid are urgently required. More recently, the Electric Reliability Council of Texas said this summer will bring a 16% chance of an electrical grid emergency and a 12% chance of rolling blackouts.
After the winter storm of February 2021, we saw a bump in solar and battery installation, and we’re likely to see an additional bump following the recent storms. Households and businesses across the state are realizing that by going solar they can reduce their electricity bills and increase the reliability of their power supply. According to a recent Environment Texas report, Texas ranks third in the nation for rooftop solar, growing more than 646% from 2017 to 2022.
Even the city of Dallas is getting in on it, with plans to install 739,000 kilowatts of solar capacity by 2030 and 3,695,000 by 2050. And thanks to state and federal incentives — including tens of billions of dollars available from the Inflation Reduction Act — it’s more affordable than ever to make the switch to solar.
But the momentum behind rooftop solar is in danger of getting tangled up in local government red tape. Once families or businesses make the decision to go solar, they often have to navigate a needlessly slow and costly permitting process. Every application to install rooftop solar has to be approved by a city employee, who might have to manually work through 100 compliance checks and get approval from structural, electrical, fire, planning and zoning departments.
According to the National Renewable Energy Laboratory’s SolarTRACE database, in 2022 it took an average of 22 days to obtain a residential rooftop solar permit from the city of Dallas, while Fort Worth took 4 days and the average Frisco permit was approved within 24 hours.
We spoke to local solar installers from Texas Best Solar, Hoss Solar and Solar Cowboys, who said that recent Dallas applications took between two weeks and, in one case, 52 days. A major city like ours can do a lot better.
In order for Dallas to meet the solar goals in its Climate Action Plan, we need a permitting process that can scale to meet the increasing number of applications in a timely and efficient manner, without compromising on safety and other necessary checks. Thankfully, there’s a tried and tested app for that. SolarAPP+, developed by the U.S. Department of Energy, is a free web-based portal which automates permitting in a quick, reliable process.
Hundreds of cities are already successfully using SolarAPP+ to quickly and smoothly allow residents to install reliable rooftop solar energy and the lower bills that come with it. Houston and San Antonio are already piloting the service. The National Renewable Energy Laboratory estimates that in those areas where it is being used, SolarAPP+ saved around 15,400 hours of local government staff time in 2023, and sped up the permitting process by an average of 14.5 days.
In December of last year, Dallas’ Environmental Commission voted unanimously to recommend that the city’s permitting department adopt SolarAPP+.
With the city’s bold climate goals, ongoing struggles with air pollution, and the public clamoring for clean energy, the next step is clear: We need more solar and less red tape.
In the coming years, the majority of Dallas homes and businesses could be generating their own reliable, clean, affordable energy, directly from their rooftops. They could break free from reliance on utility companies and polluting power plants located miles away. But to build the clean, reliable power grid of the future, we need to act quickly to change our approach to permitting.

Misinformation and disinformation are at all-time highs in recent years, not only in politics, but also when it comes to protecting our environment and improving the use of our resources.
Although a Pew Research Center survey found last June that “67% of U.S. adults prioritize the development of alternative energy sources such as wind, solar and hydrogen power over increasing the production of fossil fuel energy sources,” these positive thoughts can be quickly undermined when false narratives enter the picture, as highlighted in Solar Today‘s article last month, It’s Time to Stand up for Solar.
Much of the disinformation on renewables originates from “deliberately misleading sources,” such as bogus so-called “local” organizations, ultimately funded by those in the fossil fuel industry, according to a recent report from Columbia Law School’s Sabin Center for Climate Change Law, “Rebutting 33 False Claims About Solar, Wind, and Electric Vehicles.” The report looked at the 14 most commonly circulated false claims and refuted them with the goal of providing correct information to communities.
Since going into all of them would create an exceptionally long article, I have pulled a few of the most outrageous ones mentioned in the report, with the Center’s debunked responses.
False Claim #1: Electromagnetic fields from solar farms are harmful to human health.
Multiple studies have shown that electromagnetic fields (EMFs) created on solar farms are not harmful to humans and in fact are “similar in strength and frequency to those of toaster ovens and other household appliances.” The highest emissions of EMFs on solar farms come from inverters, and “even when standing next to the very largest inverter at a utility-scale solar farm, one’s exposure level (up to 1,050 milligauss, or mG) is less than one’s exposure level while operating an electric can opener (up to 1,500 mG), and well within accepted exposure limits (up to 2,000 mG).”
False Claim #2: Toxic heavy metals, such as lead and cadmium, leach out from solar panels and pose a threat to human health.
The cadmium sometimes found in solar panels (used in about 40% of new panels in the U.S. and 5% of new panels in the world) is actually cadmium telluride—a non-volatile, non-water-soluble material with “1/100th the toxicity of free cadmium,” which is encapsulated in the panel.
Small amounts of lead can be found in most solar panels, as it is in many electronics. According to the Massachusetts Department of Energy Resources (DER), however, “because PV panel materials are enclosed, and don’t mix with water or vaporize into the air, there is little, if any, risk of chemical releases to the environment during normal use.” They further found that “even in the unlikely event of panel breakage, releases of chemicals used in solar panels are ‘not a concern.’” The study points out that all materials in the panel are “encased in tempered glass that not only withstands high temperatures… (and are) also strong enough to pass hail tests and is regularly installed in Arctic and Antarctic conditions.” Even if one were to catch fire at temperatures hot enough to melt glass, it would still remain encased in the melted glass.
False Claim #4: Clearing trees for solar panels negates any climate change benefits.
It turns out that this is not a big issue in the U.S., as only about 4% of solar projects are being developed on forested lands here, but the report found that “an acre of solar panels in the United States usually offsets significantly more carbon dioxide emissions than an acre of planted trees can sequester.” According to the EPA’s Greenhouse Gas Equivalencies Calculator, an average acre of U.S. forest sequesters 0.857 metric tons of carbon dioxide annually. Based on the amount of emissions the average acre of solar panels displaces from natural gas-fired power plant use, they would end up reducing approximately 204–231 times more carbon dioxide per year than an acre of forest.
False Claim #5: Solar energy is worse for the climate than burning fossil fuels.
Overwhelming evidence shows that “the lifecycle emissions of solar energy are far lower than those of all fossil fuel sources, including natural gas,” according to the report. “On average, it takes only three years after installation for a solar panel to offset emissions from its production and transportation. Modern solar panels have a functional lifecycle of 30–35 years, allowing more than enough time to achieve carbon neutrality and generate new emissions-free energy.”
False Claim #10: Utility-scale solar farms destroy the value of nearby homes.
Multiple studies have shown that solar farms typically have nominal impact on the value of the homes closest to it. The report cites the largest study to date, covering six states and 1.8 million homes, which found that homes “within 0.5 miles of solar farms were found to experience price reductions of 1.5%, compared to those 2–4 miles away… and homes located more than 1 mile from a solar farm had no statistically significant price difference.” Other studies found no impact on homes in rural areas, as opposed to those with a slight difference in suburban areas, where space is more competitive.
False Claim #11: Solar energy is more expensive than fossil fuels and completely dependent on subsidies.
The report shares that “unsubsidized solar energy is now generally cheaper than fossil fuels” and that according to the International Energy Agency, photovoltaic solar power is “the cheapest source of new electricity generation in most parts of the world,” and “now the cheapest source of electricity in history” for projects with low-cost financing that tap high quality resources.”
They also note that fossil fuels continue to receive subsidies—$2.1 billion in 2022—although that is now less than renewable energy receives.
False Claim #12: Solar panels don’t work in cold or cloudy climates.
Although clouds can reduce solar power by up to 45%, solar panels do continue to generate energy. Cold temperatures do not affect output at all, however, and actually “increase solar panel efficiency by increasing voltage.”

You’ve probably seen the headlines this past week from ERCOT (Electric Reliability Council of Texas), including:
It all comes down to a very simply concept — Supply and Demand.
When considering the problems ERCOT is having in trying to meet the growing demand for energy, it is time they took into consideration all possibilities. This includes not only demand, but all the options for supply.
Investors are developing solar power and storage at an unprecedented rate and the costs have dropped to the point that the technology is cheaper than coal as well as natural gas (see “Texas solar surpasses coal production for first time”). But intense demand could overwhelm all that new supply, and then some.
Demand hit 85 gigawatts last summer and ERCOT recently estimated that Texans would need 92 gigawatts of electricity to weather another Winter Storm Uri.
With an expected flood of demand from large loads, including data centers, electric vehicle fleets and much, much more coming online in Texas, demand will rise even higher and faster.
Without higher demand flexibility, the grid simply will not be able to keep up and Texans will face higher electricity bills and more blackouts.
If investor-owned utilities would take advantage of all the options available, including energy efficiency, demand response and incentivizing rooftop solar it would cost much less than new power plants needed to meet the demand that we will be facing. It would make the grid stronger and save Texans money.
Last year the legislature required the Public Utility Commission of Texas to pass a rule to reduce average residential load, but so far the PUC has ignored this legislative requirement, although they did recently hire a new director of energy efficiency. So, there is hope.
If we try to keep up by just building enough infrastructure, and dispatchable generation from gas plants to simultaneously cover peak electricity needs without considering the exploding demand, the grid will be one of the most expensive and least reliable in the world.
The good news could come from distributed solar power. Distributed solar’s ability to increase customer resiliency and predictability against the expected rise in the cost of electricity, will be vital as the state moves forward. And if storage is added, that reliability will increase several fold.

“There are a lot of great solar installers in the industry who provide reliable products to build affordable arrays with quality and skill. However, from time to time, we hear reports of the ‘other guys’ – the companies that are in it to make a quick buck and move on to the next sale.”
TXSES Executive Director Patrice “Pete” Parsons co-authored the Op-Ed, “Protecting Yourself from the ‘Other Guys’“ on what to watch out for when getting solar panels installed in Solar Today magazine with Roger Horowitz (Solar United Neighbors) and Rich Strömberg (ASES Photovoltaics Division).
Warranty service or Operations & Maintenance? These may be lacking or nonexistent.
Solar arrays that miss the energy production estimates by a significant margin? These can leave well-intentioned array owners with a bad experience.
While this is not the norm, we want to caution would-be solar-array owners and provide pathways to prevent poor customer satisfaction.
Some recent anecdotes about poorly installed solar that we are personally aware of include the following:
1) A woman purchased a home with a preexisting leased solar array that was installed on an older roof. The original installer should have advised the prior homeowner to get a new roof before installing an array that would undoubtedly require removal and reinstallation before the end of the 25-year PV module warranty period.
That installer went out of business, but a new company bought the lease and now wanted to charge the woman a lot of money to remove the array for the roofers to do their work and then reinstall the system. They quoted her a price for the work equal to buying a brand-new solar array.
Since the lease company owned the array, they wouldn’t let another installer do the work at a lower cost. The homeowner was also offered a buyout of her remaining lease at a price much higher than the current value of her PV system.
2) A company installed solar panels on any available roof space instead of focusing on unshaded roof space that would have a good power-production factor.
3) A commercial solar array was mounted horizontally (instead of at an angle) on a flat roof in Florida where rainwater was allowed to pool on the modules and seep behind the front-side glass, causing rippling of the ethylene vinyl acetate encapsulant film and allowing algae to grow between the glass and the silicon cells.
Further, the inverters were mounted outside, which resulted in the ventilation fans pulling in corrosive, salty sea air into the sensitive internal electronics. This system stopped working and the customers did not have a good solar experience.
4) A commercial array in Colorado had a building owner who had a third-party power purchase agreement and was billed regularly for the supposed solar production despite the system not producing.
The installer had not worked to repair the offline inverters for more than a year, but was providing a fraudulent bill to the building owner, who was double-paying for electricity.
5) A large, extremely reputable national solar company worked with a company that was providing it sales leads in the Houston area. After the large company had installed a system based on one of these leads, the customer didn’t understand why her bill was not zero.
She had been promised by the salesperson that her solar array would cover her entire electric bill. She didn’t have a clear understanding of the contract and certainly didn’t understand the credit that would be paid to her.
When the solar company heard about all the promises that had been made on their behalf, they went back and repaid her the entire amount of the system, which was fortunate for her in this case, but there are plenty of examples of these poor practices happening across Texas.
While several of these anecdotes relate to leased arrays, this is not to say that all leased arrays should be avoided. In many larger commercial arrays, any system larger than what is allowed for net metering (typically larger than 25 kW) is frequently owned by a solar company that operates and maintains the system and sells the power produced to the building owner at a rate less than the utility retail rate.
Residential lease arrays might be an attractive option for homeowners who don’t want to buy or finance their own systems. The primary considerations for leased arrays are 1) to be cognizant that the lease is an encumbrance should the homeowner wish to sell their home before the end of the lease period and 2) to seek transparency about the energy produced and system health/performance.
What are the costs to buy out the lease early? Are there penalties to an installer if the system underperforms? What are the costs and logistics if the array needs to be removed for roof repairs? These factors might cause a prospective solar array owner to revisit a home equity loan or even forego a solar array until a later date.
Inspired by the Inflation Reduction Act of 2022, lots of folks are interested in installing solar all over the country. Along with reputable solar companies, there are plenty of solar scams and misleading solar advertisements out there, particularly on social media. Here are several pathways a prospective solar-array owner can follow to protect their interests and ensure the best possible option based on their particular needs.
1) You should beware of ads and salespeople claiming free systems or a time-limited program that you need to sign up for immediately.
2) Some companies are counting on you not doing your research and selling expensive systems or systems without warranties. Do you really need an array this large? Is a battery/energy storage system actually needed if the local utility doesn’t have time-of-use rate structures?
Time-of-use rates are used when an electric utility charges a higher per-kWh rate at times each week when energy demand is high and lower rates when demand is low.
A battery energy storage system can help the array owner draw excess power from the battery rather than from the grid during high-usage-rate periods. The system can also push excess power back onto the grid during high-usage-rate periods and use nighttime power from the grid to recharge the battery when usage rates are low.
2) Solar United Neighbors (SUN) has a National Solar Help Desk (https://www.solarunitedneighbors.org/helpdesk), which provides free support for people looking to go solar. SUN is a 501(c)(3) nonprofit that can help you find local installers and can review solar proposals and contracts free of charge. We and SUN always recommend getting three solar proposals and making sure to check the warranties on the systems to make sure that the installer and manufacturers have a long-term plan to help you if your system isn’t working.
3) In general, we recommend using the monitoring app that comes with your solar systems to track performance. We also advise having a solar professional take a look at your system in person every five years.
4) When it comes to choosing an installer, make sure to read every online review that you can find and call or meet multiple local references from the solar installer. A lack of local references and lack of online reviews is generally a red flag when it comes to solar companies. Scrutinize these online reviews to confirm their legitimacy.
5) Talk with your neighbors who have solar arrays.
6) Lastly, join your local chapter of the American Solar Energy Society (www.ases.org) to network with system owners who can provide advice and share their knowledge.
Best of luck in finding the right solar array for your needs. We love our systems and want the same for you.
