Thinking solar will automatically slash your bills? That assumption is being seriously tested in 2026. The rules of the game have changed, and your financial outcome now depends entirely on your strategy.
For years, a generous federal tax credit made going solar a no-brainer. That era is over. Now, homeowners exploring solar feel like they’re trying to read a map in the dark—a bit ironic, no? This uncertainty leaves many wondering if the investment still makes sense, especially when they’re planning on buying a home in San Diego or preparing to sell one.
The 30% federal solar tax credit is gone for most new installs in 2026. But with smart financing & high energy costs, the sun hasn’t set on savings.
Imagine a homeowner, let’s call her Maria. She’s been planning to install solar on her Clairemont house for two years. The “Normal” was saving up, knowing a 30% credit would slash the final cost. Then came the “Explosion”: news broke that the credit she counted on won’t apply to her 2026 installation. Suddenly, her budget is upside down, and the entire project is in jeopardy.
This guide is for Maria, and it’s for you. We’ll outline the “New Normal”—a data-driven path to determine if solar is still a brilliant move for your property’s value.
Check if your home is a prime candidate for solar
Before you get lost in quotes and proposals, you need to know if your property even makes the cut. Skipping this step is a high-risk gamble.
Evaluate your roof’s condition and sun exposure
The common wisdom—the “Normal”—is that you need a massive, perfectly south-facing roof with zero shade. While that’s the ideal, it’s no longer the whole story.
-
The Explosion: Panel technology and racking systems have advanced dramatically. East-west facing roofs are now highly effective power generators.
-
The New Normal: You can generate significant power even without perfect orientation. However, your roof’s condition is non-negotiable. A solar panel system is designed to last 25-30 years. If your roof has less than 15 years of life left, you must address it first. Rolling a new roof and solar into one project is an option, but get separate quotes to see the true cost of each.
Review your utility bills and HOA rules
Your electricity usage dictates your system’s size and potential savings. A low bill is a major risk factor for a poor return.
▶ If your monthly electric bill is under $75, the payback period could be so long that most installers won’t even take the project.
▶ Pull your last 12 months of bills from SDGE. This data is the absolute foundation of any accurate solar proposal.
Then there’s the HOA. Before you dream of panels, read your covenants. While California has “solar access” laws that limit an HOA’s ability to outright prohibit installation, they can still enforce aesthetic rules. Don’t start a war; start a conversation.
Break down the costs of a 2026 solar system
Let’s talk numbers—real ones. Vague estimates are a waste of time.
As of early 2026, the average 12-kilowatt (kW) residential system costs about $30,500 before any incentives, according to solar marketplace data. That price fluctuates based on your location, equipment choices, and installation complexity. For anyone tracking San Diego home prices, understanding this cost is critical to calculating your home’s total value proposition.
The real story isn’t just the sticker price; it’s the net cost after incentives and the long-term impact on your property’s equity. A fully-owned system can be a powerful asset when you’re selling your house in San Diego, but a leased system can become a major liability.
Choose your financing with the new rules in mind
With the federal tax credit landscape shifting, how you pay for solar is more important than ever. Your choice here carries significant financial tradeoffs.
Cash Purchase
This is the most straightforward path. You pay upfront, own the system outright, and reap all the rewards.
■ Benefit: No interest payments and the maximum possible return on investment.
■ Risk: It requires a significant amount of liquid capital.
Solar Loan
You finance the system and pay it off over time, typically 5 to 20 years. Monthly loan payments are often structured to be lower than your old electric bill.
■ Benefit: You own the asset and can benefit from any available state or local incentives.
■ Risk: You’ll pay interest, which increases the total cost of the system over its lifetime.
Solar Lease or PPA (Power Purchase Agreement)
Here, a third-party company installs panels on your roof, and you pay them a fixed rate for the electricity produced. You do not own the system.
■ Benefit: Little to no upfront cost.
■ Risk: This is a huge one. You don’t own the panels, which can seriously complicate a home sale. We’ve seen buyers walk away from otherwise perfect homes because they didn’t want to assume a 20-year solar lease. A first time home buyer in San Diego is already navigating a complex process; adding a lease assumption can be a deal-breaker.
Navigate the 2026 solar incentive maze
The incentive landscape used to be a simple, straight road. Now, it’s a patchwork quilt of federal policies, state programs, and local utility rebates.
Understand the federal tax credit changes
The Residential Clean Energy Credit, which offered a 30% tax credit for owned systems, is no longer available for most new systems placed in service after December 31, 2025. This is the single biggest financial shift for homeowners considering solar in 2026.
However, a “New Normal” is emerging to fill the gap. Some companies now offer financing structures like prepaid solar leases that can mirror the 30% savings upfront. This is a compelling alternative, but it requires careful vetting of the provider and the contract terms.
Explore state and local incentives
With the federal credit gone for many, the focus shifts to state and local programs.
➜ Start by checking the Database of State Incentives for Renewables & Efficiency (DSIRE) online to see an overview of available programs.
➜ Ask your utility directly about net metering policies. California’s new NEM 3.0 rules have changed how you get credited for excess energy, making battery storage an increasingly vital part of the equation.
Find an installer you can actually trust
Choosing your installer is the most critical decision you will make. A bad installation can damage your roof, underperform, and torpedo your home’s value. I once tried to fix a simple sink leak myself and ended up creating what my wife generously called an “internal water feature.” Don’t be like me. Hire a verified professional.
A reputable installer is your strategic partner. At The Cassity Team, we rely on a network of vetted professionals—from lenders to contractors—because we know an expert team is non-negotiable. Your solar installer is no different.
▶ Get at least three quotes. This is your non-negotiable first step. Comparing offers is the only way to understand the true marketplace pulse.
▶ Verify their credentials. Are they licensed and insured? Do they hold certifications from an organization like NABCEP?
▶ Read third-party reviews. Don’t just look at testimonials on their site. Dig into Yelp, Google, and other independent platforms to see the full picture.
▶ Ask for references. A great installer will happily connect you with past clients who can vouch for their work.
So, is solar still worth it in San Diego?
For many, the answer is still yes—but the calculation has changed. With San Diego’s high electricity rates, the payback period for an owned system remains attractive, even without the old federal credit.
An owned solar system can increase your home’s value. A leased system? It often becomes an obstacle. When we develop a go-to-market playbook for a property, the type of solar contract is a major strategic point. If you’re looking at homes with exclusive access, understanding the terms of an existing solar installation is a critical part of your due diligence.
The final decision depends on your property, your electricity usage, and your long-term financial goals.
