What Is the HDM Prepaid PPA
— and Why Does It Save So Much?
A Smarter Structure,
A Bigger Discount
With Ally's HDM (High-Discount Model) Prepaid Power Purchase Agreement, you pay one discounted lump sum for your solar and battery system — typically 30 to 40% less than the standard retail cash price. There are no monthly bills, no escalators, and no hidden fees.
How is this possible? As the commercial entity, Ally assumes the applicable commercial tax incentives and structures them into a lower up-front price for you — without requiring you to have a tax liability yourself. The savings pass directly to your pocket at signing.
It's not a lease. It's not a loan. It's a prepaid agreement with a built-in ownership transfer — so you end up owning a fully paid-off system, positioned to generate decades of free electricity for your home.
How the HDM Prepaid PPA Stacks Up
Six Reasons Bay Area Homeowners
Choose the HDM Prepaid PPA
No gimmicks, no fine print traps. Just the most affordable path to owning solar in the Bay Area.
Deepest Discount Available
Save 30–40% compared to paying full cash price for an equivalent system. That's thousands of dollars back in your hands at day one.
Zero Monthly Payments
Unlike a loan or traditional PPA, there's no monthly bill. Pay once and your obligation is complete — period.
You Own Your System
Ownership transfers automatically at the end of the agreement. No additional fees. The system is yours, adding real value to your home.
Rate Protection
PG&E rates have risen over 50% in the last decade. Go solar now and lock in your energy cost — before the next round of increases hits.
Battery Backup Included
Add a Tesla Powerwall, Enphase, or FranklinWH battery to your system under the same HDM structure — backup power at a fraction of retail.
Licensed Bay Area Experts
Ally holds C10 and C46 CSLB licenses and has served Alameda, Contra Costa, Marin, and Santa Clara Counties since 2010.

Get Your Free Custom Estimate
Ally's Bay Area solar experts design a system sized for your actual usage — solar panels, battery storage, or both. We calculate your HDM discounted price and show you your projected savings over 25 years side-by-side with your current PG&E trajectory.
Pay Once — Then Relax
You make a single upfront payment at the HDM Prepaid PPA price — 30 to 40% below standard retail. Ally handles permits, interconnection, and installation. From that point forward: no bills, no escalators, no surprises. Your system starts generating power immediately.
Own Your System — Free & Clear
At the end of the agreement term, ownership automatically transfers to you at no additional cost. With 25–30 years of system life remaining, you'll enjoy decades of deeply discounted or free electricity — and a home that's worth more on the market.
