6 Top Solar States That Have Renewable Regulations
6 Top Solar States That Have Renewable Regulations
You’ve probably noticed panels popping up on the rooftops of the busy buildings downtown, or heard rumblings about new energy laws. It’s a hard movement to ignore, especially when you consider that the push for renewable energy is now written into the rulebooks of states across the country.
Whether you’re a small business owner looking to cut overhead or a commercial construction company wondering how the laws affect you, understanding these regulations is your first step.
In this guide, we’ll walk you through some of the states that are leading the charge. What may surprise you is that some of these aren’t places that “just have good weather,” but instead, are states with legislation that actively encourages (and often mandates) solar adoption. You might be surprised by who made the list, because it’s not just the sunny, coastal states.
Let’s look at the specific laws and regulations shaping solar right now.
1. New Jersey
New Jersey might be small, but it’s punching way above its weight class when it comes to solar. You’d think the Garden State would be quiet on this front, but the legislation here is aggressive, especially if you’re in the commercial sector.
The biggest news comes in warehousing. If you’re building a new warehouse that’s over 100,000 square feet, effective in 2022, the state now mandates that you reserve up to 40% of that roof space for future solar installations.
While the rule only applies to warehouses here, just think about the sheer number of distribution centers along the Turnpike. It’s acres of potential energy generation.
As a developer, this regulation will force you to think ahead, because you can’t (or, at least, you shouldn’t, as far as best practices go) just retroactively decide to add solar later if the building wasn’t designed to handle the load or the electrical infrastructure. By mandating the “solar-ready” zone, New Jersey is effectively banking roof space for the future grid.
And if you’re a business owner, you also need to pay close attention, as this regulation signals where the market is going. If you’re operating in New Jersey, the state is making it very clear that they expect commercial buildings to be power plants, not just storage facilities in a smart move that presses on the state’s density and industrial footprint to generate clean power right where it’s needed most.
2. Massachusetts
Head due north to Massachusetts, and you’ll find a state that’s been ahead of the curve for years. The state has written solar mandates directly into the building code, with the big player being the “Stretch Energy Code.”
If you’re building commercially in a municipality that adopted this code, your new construction needs to be solar-ready. Being “solar-ready” means planning for the conduit, roof load, and electrical panel space from the architectural drawing phase. In other words, you can’t treat solar as an afterthought.
Massachusetts also has the SMART program (Solar Massachusetts Renewable Target). This is a tariff-based incentive that pays solar system owners for every kilowatt-hour they produce and is a gesture that’s designed to provide long-term stability for investors. You know exactly what you’re getting paid for the energy you generate, which makes the financial modeling for a new system much easier.
This combination of building codes and financial incentives creates a robust market, with solar springing up on schools, government buildings, and municipal structures alike because the state made it easy to do and hard to ignore. If you’re building in Massachusetts, you’re likely already planning for solar whether you intended to or not.
3. Colorado
Colorado has always been known for its outdoor lifestyle, so it makes sense they’d want to protect that environment. The legislation here is getting very specific, very fast.
For commercial properties in Denver, recent legislation is driving even more momentum. In 2021, the city passed new commercial building energy requirements that set strict standards for energy efficiency, carbon reduction, and on-site renewable energy generation, including solar.
The Energize Denver ordinance mandates that large commercial and multifamily buildings (with various language for buildings of different sizes) reduce their greenhouse gas emissions significantly by 2040. Though the ordinance covers other energy efficiency upgrades as well, solar installations are one of the most cost-effective ways for building owners to comply.
SB24-207, passed in 2024, similarly expanded access, stating that by February 1, 2026, an investor-owned electric utility with more than 500,000 customers must make at least 50 megawatts of community solar capacity available. More regulations affecting commercial solar are likely to come. Just three months into 2026, Colorado legislators have already introduced 18 energy-related bills, all with the goal of reaching net zero by 2050.
It’s also worth noting that Colorado has strong net-metering laws. For those unfamiliar, all this means is that when your panels produce more energy than you use, the utility company has to credit you for that excess power. It’s a one-for-one swap in many cases, which makes your electric meter spin backward, and it’s also one of the best ways to make sure your investment pays off quickly.
The Enterprise Zone Redesignation Tool
Understanding these new rules and regulations can be tricky, particularly in places like Denver, where laws vary based on your property’s size and use. However, Colorado has taken extra measures to help businesses plan and invest, most notably in the launching of new mapping tools and resources.
The Enterprise Zone Redesignation Tool displays in detail which areas qualify for incentives, with the different colors on the map representing various Census geographies (like counties, tracts, block groups, designated places, and subdivisions) that may qualify for tax incentives under the Enterprise Zone Program. There’s also a sublayer for ‘graduated out’ areas, indicating Census blocks that no longer qualify for incentives based on the latest economic and demographic data.
4. Illinois
You might not think of the Midwest as a solar hotbed, but Illinois is quietly becoming a powerhouse thanks to the Climate and Equitable Jobs Act (CEJA). This legislation, passed in 2021, is ambitious, with the goal of putting the state on a path to 100% clean energy by 2050.
The state uses a system of Solar Renewable Energy Credits (SRECs) through the “Illinois Shines” program. When you install a system, you save on your electric bill, but you also generate these credits, which the state or utilities then buy from you. This exists as a significant upfront or ongoing payment that can cover a large chunk of the installation cost.
The incentives here are attractive for commercial projects, as the state is pushing hard to replace coal plants with renewable capacity, and they need distributed generation (meaning solar on roofs and in fields) to make that happen.
If you’re in Illinois, you also benefit from strong net metering policies. ComEd and Ameren, the big utilities, are required to credit you for excess generation, which makes the economics of solar in Chicago or Springfield look very different than they did ten years ago.
Although the metrics of this law have changed (prior to January 2025, solar owners received a 1:1 credit for every kWh sent to the grid, while now, you receive credit only for the supply portion of your bill with delivery charges no longer offset), it’s still one of hte most effective ways to reduce electricity prices.
5. Florida
They call it the Sunshine State for a reason, but for a long time, Florida lagged behind on renewables policy. Thankfully, that’s changing, mostly due to market forces and the sheer logic of solar in a state with this much sun.
Florida doesn’t have a statewide renewable portfolio standard like other states on this list, but it does have excellent net metering policies, which are currently protected. This means if you install solar in Miami or Orlando, you get full retail credit for the energy you send back to the grid.
It also lacks new construction regulations for solar, though all new construction must comply with the 2023 Florida Building Code, which focuses on energy efficiency (namely through things like lighting and HVAC) instead of a push towards renewables.
The state also offers a property tax exemption for renewable energy property. If you add a $30,000 solar system to your business, your property taxes don’t go up because the value of the property increased, which exists as a direct saving that stays in your pocket every year. Commercial systems qualify for this at 80%.
Florida also offers a sales tax exemption on solar energy systems. That’s 6% right off the top of the project cost. When you’re talking about a large commercial array, those savings add up fast. While there aren’t heavy mandates forcing you to build solar, the financial environment is set up to reward you if you do. It’s an approach that’s less stick, more carrot.
6. Texas
Everything is bigger in Texas, and that includes the energy market. Texas is the Wild West of power because it has its own grid (ERCOT), which is separate from the rest of the country. This independence allows for rapid changes and deregulation.
Texas is currently a leader in wind, but solar is catching up fast. The regulatory environment here is incredibly friendly to development, and while there aren’t many regulations requiring solar for new construction, there’s very little red tape compared to coastal states. If you have land and you want to build a solar farm, you can do it relatively quickly.
The Texas Government Code 2166.403 states that alternative energy must be considered in construction plans if it’s economically feasible to do so.
The lack of a statewide net metering mandate in Texas can be tricky. But because the market is so deregulated, you have dozens of retail electric providers competing for your business. Many of them offer solar buyback plans to attract customers with panels. You have to shop around, but the deals are there.
Powering the Future, One State at a Time
The landscape of solar regulations is a patchwork quilt. What works in New Jersey might not apply in Texas. But the trend line is undeniable. States are realizing that renewable energy isn’t just good for the planet; it’s also good for grid resilience and economic growth.
Understanding, decoding, and working around these regulations can be a headache if you try to do it alone. You need to know which permits to pull, which incentives to file for, and how to design a system that meets local codes.
But don’t let the paperwork scare you off. The long-term savings and energy security are worth the initial legwork.
If you’re ready to stop renting your power and start owning it, you need a team that understands the local laws inside and out. You need someone who can look at your specific situation, whether it’s a warehouse in Jersey or a home in Colorado, and build a solution that maximizes every available credit and code.
