The Truth About Solar Savings in 2026: Why “30% Off” Isn’t What It Seems

The residential federal solar tax credit (Section 25D) officially expired for homeowner-owned systems after December 31, 2025. As of 2026, if you purchase and own a solar system outright, you no longer qualify for that direct 30% credit against your federal taxes. This shift has reshaped how homeowners in Sonoma County, California, approach solar, particularly with high PG&E utility rates and the Net Billing Tariff (NEM 3.0) rules in place.

Fortunately, solar incentives haven't disappeared completely. Companies like HDM Renewable Finance can still access the commercial clean electricity investment tax credit (Section 48E) by structuring deals where they own the system initially as a business entity. Through their prepaid Power Purchase Agreement (PPA) model, HDM claims the tax credit, accelerated depreciation, and related benefits, then passes a portion of those savings to you as an upfront discount on your prepaid amount for 20–25 years of solar energy production.

Why a True 30% Reduction Isn't Realistic with Prepaid PPAs

While the commercial credit remains at 30% (or higher with potential bonuses), providers like HDM don't pass along the full value directly to homeowners. They retain a share to cover their operational costs, risks, profit margins, administrative expenses, and the responsibilities they take on, such as owning the system and providing performance guarantees for the first ~6 years.

In real-world 2026 scenarios, the most common discount homeowners receive through legitimate HDM-partnered prepaid PPA programs is around 20% off the fair market system price. This delivers substantial, immediate savings, often comparable to or better than the old residential credit when factoring in tax liability requirements, but it's not a full 30% pass-through.

Beware the "30% Discount" Mirage: Inflated Pricing Remains Common

In this post-residential-credit world, many solar companies are marketing aggressive "30% discounts" to mimic the feel of the expired ITC. The catch? A significant number first inflate the base system price by 10% or so above actual market value and then apply that 30% "discount" to bring the net price back in line with a standard, transparent quote.

Real-world example tailored to Sonoma County:

• Fair market price for a quality mid-sized system of about 7kw of solar with one battery you are likely looking at around $30,000–$40,000 before the roughly 20% discounted. The net amount of this system would be around $24,000-$32,000

  
  

• Deceptive quote: Company lists $34,300–$45,800 (inflated pricing), then promotes a "30% exclusive discount" → net $24,010–$32,060.

  
  

• Outcome: You end up paying roughly the same net amount as a no-nonsense quote, but the advertised "savings" are fake. This often conceals lower-grade equipment, unnecessary upsells, or hidden fees.

These tactics rely on creating urgency and perceived value ("Don't miss out on 30% off!"), but they mislead consumers. Industry reports and consumer feedback continue to highlight such deceptive sales practices in solar financing.

Quotes are getting harder and harder to compare with many quotes having very limited information. Many quoting tools leave out the racking or roof attachments, which are some of the most important parts of the system. At first Response Solar we are always happy to help homeowners decipher the differences between quotes to help them make the most informed decision.

Even though we have an owner onsite for every installation (C-10 & C-46 contractor), we run conduit in attics whenever possible, we install extremely high quality roof attachments and our workmanship is one of the best in the industry, we are usually only a little higher or about the same as most competitors.

First Response Solar's Commitment to Transparency

At First Response Solar, we stand apart by keeping things straightforward. We partner directly with HDM Renewable Finance and pass along the exact discount we receive, no artificial price inflation, no exaggerated claims, no deceptive tactics.

• We present the real system price based on fair market value from the start.

• We apply the genuine HDM prepaid PPA discount—typically around 20% in today's market.

• You receive a clear prepaid amount that eliminates monthly solar bills, includes professional monitoring and leads to full ownership transfer after approximately 6 years.

This honest approach cuts through the industry's current "Wild West" marketing noise. You're getting verifiable benefits from the commercial incentives that remain available, without the spin that leaves many homeowners feeling misled.

Why This Matters for Sonoma County Homeowners in 2026

Solar continues to be a strong choice in Sonoma County, where PG&E rates remain high (around 30–65 cents per kWh depending on your plan, time and usage. NEM 3.0 emphasizes self-consumption, making solar and battery storage especially valuable for maximizing savings by using your generated power during expensive evening peak hours instead of exporting at low avoided-cost rates.

The end of the direct 30% residential credit is a hurdle, but prepaid PPA options like HDM's provide a reliable path forward, delivering around 20% upfront savings and zero ongoing solar payments.

First Response Solar is based and service's Sonoma County and some surrounding areas. We are offering both HDM and direct homeowner purchases. There are pros and cons to both and it really comes down to each individual homeowner on what option works best based on their specific situation. If you are looking at the prepaid PPA's make sure to look our for deceptive marketing as we are seeing it a lot across our industry right now.

If you are interested in learning more or would like a quote for your home in Sonoma County, we would be honored to help you with your transition to solar and storage energy!
