Is Solar Worth It in California? What Reddit Really Thinks After NEM 3.0 (2026)

Type "is solar worth it in California" into any search box and you'll see the same suffix people keep adding: reddit. Fair enough — this is the one question where homeowners most want an answer from someone who isn't selling panels. So here's the honest version: we traced the Reddit debate from the 2023 NEM 3.0 panic through the 2025 "do you regret it?" follow-ups to the 2026 court ruling, linked every thread, and compared Reddit's verdict to the numbers we model on real Southern California roofs.

Disclosure up front: we're Helios Energy Global, a solar and battery installer in Santa Monica. Every quote below belongs to its Reddit author and links to the original thread — including the ones that argue against buying solar.

2023: the panic era

When NEM 3.0 cut export credits by roughly 75% for SCE, PG&E, and SDG&E customers, r/solar's reaction was blunt. The thread titled "California solar, ruined?" collected hundreds of comments arguing the export-credit cut had gutted the old solar-only math, with talk of oversizing arrays or quitting the grid entirely. The mood was well captured by u/Jenos00: "NEM3 was only the first attack."

In the more sober "is it still worth it" thread, the split emerged that still defines the debate. Skeptics like u/magbarn challenged rosy payback claims: "How can you say you'll pay it off in 5-7 years with NEM 3.0? You're looking at at least double that." The counterpoint, from u/TaintCommanderz, was about the other side of the ledger: "Utility rates will only go in one direction (hint: it ain't down)."

And in NEM 3 — how does it ever pay off?, an installer (u/dcsolarguy) staked the claim that would age well: "I'm seeing 6-7 years regularly under NEM 3.0 rates. Just need solid efficiency & system pricing" — with a battery and self-consumption doing the heavy lifting.

2025: the regret check

Two years in, someone asked the only question that matters: for those who installed solar after NEM 3.0 — do you regret it? The answers, in both the r/bayarea original and its r/solar twin, skewed clearly toward no regrets — with a pattern. The satisfied owners had paired solar with batteries, shifted usage into daylight hours, or both. One no-battery owner, u/ShortAsianPenis, explained why he still had no regrets: "I didn't opt for batteries and still don't regret it because I calculated my savings before I made the purchase" — he charges two EVs from midday production.

The anger in those threads wasn't about the panels. It was about rule changes moving the goalposts on people who'd already bought, summarized by u/lampstax: "Think of the working families who invested in solar systems relying on the terms of the CONTRACT only to have it changed after the fact." A fair warning: in California, the regulatory ground moves, which is an argument for conservative math, not for waiting forever.

2026: the rules are settled — and the math is what it is

This May, r/solar covered the news that NEM 3.0 survived its final court challenge. The export cut is here to stay, and the thread's tone was less outrage than acceptance of the new playbook: solar plus battery, sized for self-consumption. The lingering resentment is real, though — as u/DownAndOutInSValley put it: "In California we get charged to send power to the grid and to get power delivered."

So what's Reddit's actual verdict?

Read enough threads and the consensus is surprisingly consistent. Solar is still worth it in California if you build for the new rules: pair a battery (or shift heavy loads like EV charging into daylight), size to your own consumption instead of oversizing to export, and buy at an honest price — the 6-to-9-year paybacks people report all start with a fair per-watt number. It's not worth it if you have a small bill, expect NEM 2.0-era exports, or sign whatever a door-knocker puts in front of you.

That maps almost exactly to what we model on real SoCal roofs: solar-only payback of roughly 10–14 years under NEM 3.0, and about 6–9 years with a battery — and meaningfully different math for LADWP, Pasadena, and Riverside homeowners, whose municipal utilities never adopted NEM 3.0 at all. Reddit rarely mentions that last part, and in the City of LA it changes the answer.

Frequently asked questions

What does Reddit say about solar payback in California under NEM 3.0?

The range you'll see across threads: skeptics argue solar-only payback stretched past 10 years, while owners and installers report 6–9 years with batteries and self-consumption. Both are right — the design determines which case you're in.

Do people on Reddit regret going solar after NEM 3.0?

In the 2025 "do you regret it" threads, most post-NEM-3.0 buyers said no — the satisfied ones paired batteries or shifted usage to daytime. The regrets cluster around undersized expectations, financing markups, and rule changes affecting earlier buyers.

Does NEM 3.0 apply everywhere in California?

No — and Reddit threads often miss this. NEM 3.0 covers the CPUC-regulated utilities (SCE, PG&E, SDG&E). Municipal utilities like LADWP, Pasadena Water & Power, and Riverside Public Utilities run their own net-metering programs with generally better export terms.

Is a battery required for solar to be worth it in California now?

On SCE, PG&E, and SDG&E, a battery is usually what restores the strong payback, because stored solar used during the 4–9 PM peak beats exporting for pennies. The main exception Reddit surfaces — and we confirm — is homeowners who can consume most production in real time, like daytime EV charging.
