How Solar Actually Saves You Money
Solar doesn't just reduce your electric bill — it fundamentally changes your relationship with the utility. Understanding NEM, true-up statements, and rate arbitrage shows you exactly where the savings come from.
“Most solar salespeople just say "you'll save money." I want you to understand exactly how and why. When you see the math, the decision makes itself.”
— Peter Galvez, The Sun Broker

Net Energy Metering (NEM) is the billing arrangement that makes solar financially viable. When your panels produce more electricity than your home uses, the excess flows to the grid and you receive a credit on your bill at a set rate. Under NEM 3.0 in California, export credits are lower than retail rates, which makes self-consumption and battery storage more important than ever.
Your true-up statement is an annual reconciliation from your utility. Throughout the year, you build up credits during sunny months and use them during darker months. At the end of your 12-month billing cycle, you settle the balance. A well-designed system targets a near-zero true-up bill.
Rate arbitrage is one of solar's hidden advantages. Under Time-of-Use (TOU) pricing, electricity costs more during peak evening hours (4-9 PM) and less during off-peak times. Solar panels produce energy during the day when rates are moderate, and with a battery, you can store that energy and use it during expensive peak hours instead of buying from the grid.
The real savings calculation involves comparing your current annual electricity cost against your solar loan or lease payment plus any remaining utility charges. For most PG&E customers with bills above $150/month, solar reduces the total cost of electricity by 30-60% over the life of the system.
Your savings grow over time because utility rates historically increase 5-8% per year while your solar payment stays fixed. A system that saves you $50/month in year one could save you $150/month by year ten simply because the utility rate has risen while your solar cost has not.
Myth Busters
Myth: Solar eliminates your electric bill entirely. Reality: You still pay a small grid connection fee, but your energy charges can drop to near zero with a properly sized system.
Myth: NEM 3.0 killed solar savings. Reality: Savings are still substantial — the economics just shifted to favor battery storage and self-consumption over pure grid export.
Myth: You need to use all your electricity during the day to benefit. Reality: NEM credits and battery storage let you offset evening and nighttime usage with daytime production.
