Incentives
When it comes to solar, incentives can make a noticeable difference in overall cost. Some are consistent and well-defined. Others depend on location and change over time. We go through all of this with each project, so everything is clear.
Federal Incentives
Federal incentives are the most widely known, but they have recently changed.
Residential Projects
For homeowners, the federal solar tax credit previously covered 30% of the system cost, including equipment, labor, and battery storage. As of 2026, that credit has ended for residential systems installed after December 31, 2025.
If a system was installed before that deadline, the credit can still be claimed. If not, there is currently no federal residential credit in place.
Commercial Projects
For commercial and business projects, the federal tax credit is still active.
In most cases, projects can still qualify for around 30% of the total system cost, depending on how the project is structured and whether certain requirements are met. There are also additional bonuses available in some cases, depending on things like labor standards or project location.
Because of recent changes, timelines and requirements matter more than they used to, so each project needs to be reviewed individually.
How Federal Credits Work
Federal incentives are tax credits, not rebates.
That means:
They reduce the amount of tax owed
They are based on total system cost
They usually require ownership of the system
They may carry forward if not fully used in one year
We always recommend confirming details with a tax professional, since every situation is different.
State, Utility, and Local Incentives
Outside of federal programs, incentives can vary quite a bit depending on location.
These may include:
State tax credits
Utility rebates
County or city programs
Net metering or export compensation programs
Some areas offer strong incentives. Others offer very little. These programs also change over time.
Because of that, we check what is available based on the project location and include anything that applies.
Referral Program
Along with standard incentives, we also offer a referral program.
If you refer someone to D4 Solar and they move forward with a project, we offer a 3% discount or credit. How it is applied depends on where you are in your own project.
To qualify:
The referred project should be of similar value or greater
The referral should ideally be completed before final payment on your system
For referrals that result in significantly larger systems, we may apply a higher custom credit based on the difference in project value.
We go through the details as part of the process so everything is clear and applied correctly.
How We Approach Incentives
We treat incentives as part of the overall project, not the deciding factor.
If they are available, we include them. If they are not, the system should still make sense on its own.
The goal is to understand what applies and make sure everything is accounted for clearly.
Incentives can help reduce the cost of a solar system, but they depend on timing, location, and project type.
We go through all of that as part of the design process so you know exactly what applies and what does not.
From there, the focus stays the same. Build a system that works and makes sense for the situation.
