How Using A Solar PPA Works with Your PG&E Bill
If you live in Sonoma County, you know that electricity is getting more expensive every year. Between heat waves and chilly winters, the bottom line on your PG&E bill has likely become a source of stress.
Many of our neighbors are looking for affordable solar in Sonoma County, but are often stopped by the upfront price tag or confusing financing terms. One of the most effective tools we have to solve this is the Solar PPA (Power Purchase Agreement), which we call Prepaid Renewable Energy Leases.
This article is an educational walkthrough to show you exactly how a PPA changes what you’ll see on your PG&E bill.
The Before Picture: 100% Dependence on PG&E
Before installing solar, a homeowner is buying every single kilowatt-hour (kWh) of energy from PG&E. At current residential rates (and depending on the time of day), that homeowner is also paying a high premium for every bit of power used during peak afternoon and evening hours.
If their monthly usage is 1,000 kWh, at present prices they might see a monthly electricity bill of around $400. This is what we call an endless financial liability. It is a payment that never stops and only goes up as PG&E raises rates to maintain a changing electrical grid.
The After Picture: How the PPA Changes the Math
A solar PPA is a "performance-based" model. Instead of buying the panels, you are simply choosing to buy your power from a different, cheaper source. A third-party provider installs and maintains a premium system on your home at no upfront cost to you.
Now, your energy comes from two places:
Your Roof: Your solar panels produce power during the day.
The Grid: PG&E provides power at night or when it is very cloudy.
Breaking Down Both Energy Bills
By upgrading your home energy to solar through a PPA, you will technically receive two statements, but the total you pay is significantly lower.
1. Your New Solar Statement
Under a PPA, you pay for the electricity the panels produce at a locked-in rate that is much lower than PG&E's retail price.
The Math: If your panels produce 800 kWh of your monthly 1,000 kWh need at a rate of roughly $0.20 per kWh, you pay $160 to the solar provider.
The Benefit: This rate is stable. While PG&E rates are volatile and aggressive, your PPA rate is predictable.
2. Your Smaller PG&E Bill
You do not cancel PG&E entirely. You just stop relying on them for your heavy lifting. You will still get a PG&E bill for:
The Connection Fee: A small monthly charge to stay connected to the grid.
Nighttime Usage: Any power you use when the sun is down.
The Result: Instead of $400, your PG&E bill might now be only $50 to $70.
Total Monthly Cost: $160 (Solar) + $60 (PG&E) = $220 In this scenario, you have gone from paying $400 to paying $220. You have saved $180 a month without writing a check for a solar installation.
Solar Hack for TOU Rates: Adding Battery Storage
The strategic value of a Prepaid Lease is maximized when paired with solar battery storage. In Sonoma County, the new NEM 3.0 rules mean that a system’s financial return is now directly tied to your ability to use power when PG&E’s Time-of-Use (TOU) rates are at their most expensive. This is typically the late afternoon and evening.
By integrating a high-quality battery, like a Tesla Powerwall, your PPA-funded system becomes a sophisticated financial tool: it charges during the day when power is abundant and discharges when PG&E's rates spike, allowing you to avoid buying expensive power altogether. As a Tesla-certified installer, Taylor Energy ensures this pairing protects not only your finances from peak-rate volatility but also your high-load appliances and home security during seasonal Public Safety Power Shutoffs (PSPS). This makes battery storage the core driver for turning a volatile bill into a stable, strategic energy investment.
Why This Makes Solar Affordable for So Many
The beauty of the PPA is that it removes the friction of going solar.
$0 Upfront Cost
You keep your savings rather than spending it on maintenance.
Hassle-Free Maintenance
Because the provider owns the system, they are responsible for it. If an inverter needs replacing in year 12, they pay for it. The system is fully insured and monitored for 25 years.
A "Discounted Utility Bill"
Think of a PPA as a "discounted utility bill" that stays with the property. If you ever sell your home, this low rate transfers to the next buyer, which is a major competitive advantage in the Sonoma County market.
