Reddit sells clicks at a blended $1.47 while commercial solar search clicks cost $15 to $50. The catch is what the click is for: on Reddit, solar quotes get audited by strangers, not signed.
Key Takeaways
- Reddit reached 130.3M daily active uniques in Q2 2026, up 18%, with 514.6M weekly uniques (up 24%).

Cost: the cheapest inventory in a solar media plan
Reddit Q2 2026 results reported by Reddit Inc. show $762M in ad revenue on 130.3M daily uniques, and benchmark data still puts pricing far below search.
| Channel | Typical cost | What you get | Role in a solar plan |
|---|---|---|---|
| Reddit traffic campaign | $0.20-$0.80 CPC ($2-$6 CPM) | Reach in research communities | Presence during quote comparison |
| Reddit conversion campaign | $0.80-$1.75 CPC, $40-$120+ CPA | Form fills, guide downloads | Secondary capture, long lag |
| Facebook / Meta | $15-$50 per lead | Volume, low intent | Top-of-funnel volume |
| Local Services Ads | $30-$80 per lead | Local high intent | Core residential capture |
| Google residential search | $40-$120 per lead | High intent | Core residential capture |
| Google commercial search | $15-$50 per click | C&I intent | Core commercial capture |
Why Reddit is a due-diligence channel for solar
Two 2026 facts define the fit. First, payback lengthened from 7.4 to 10.4 years per pv magazine USA, so buyers deliberate longer and compare more quotes. Second, per Surge PV, 88% read reviews and installers with 100+ reviews close 22% to 28% better. Reddit is where that auditing happens in public: price per watt sanity checks, panel and inverter comparisons, screenshots of competing proposals.
That means the ad has to be an answer, not an offer. Creative that publishes real numbers - price per watt, degradation warranty terms, what happens to payback without the 25D credit - performs in a community that punishes marketing language. Installers who publish pricing convert 15% to 25% higher generally; on Reddit that effect is the entire strategy.
Targeting: subreddits beat interests
Subreddit targeting delivers about 1.8x the CTR of interest targeting and Conversation Placement ads run about 0.41% CTR - roughly 2.1x home-feed inventory - while multi-placement campaigns cost about 12% less than feed-only.
| Target | Intent signal | Best format | Watch-out |
|---|---|---|---|
| r/solar | Active quote comparison | Conversation placement | Community rejects sales copy instantly |
| r/solarDIY | Self-install research | Educational carousel | Low install intent, high referral value |
| Local city / state subs | Utility rate and permit questions | Conversation placement | Small audiences, cap frequency |
| r/energy, r/RealEstate | Adjacent research | Single image | Broad; expect longer lag |
| Commercial / small-business subs | C&I roof owners | Document-style creative | 6-18 month cycle, measure on meetings |
Creative that survives r/solar
Reddit is the one paid channel where the audience can reply in public, so the creative brief is closer to technical documentation than to advertising. The objections are consistent and they are all numeric.
| Objection heard in-thread | Data to answer it with | Format that works |
|---|---|---|
| “Is this price fair?” | Median marketplace price $2.49 per watt | Price-per-watt comparison image |
| “Payback is a decade now” | 7.4 years Q3 2025 to 10.4 years Q4 2025 | Payback calculator link |
| “Installers vanish after the sale” | 51% of installers service systems they did not install | Service-commitment conversation ad |
| “Salespeople oversold my neighbour” | D2D rep turnover 60-80% | No-canvasser policy statement |
| “Will the company exist in 10 years?” | Review count and 4.7-star threshold | Review-volume proof point |
The AI-visibility argument
The strongest 2026 reason for a solar brand to be active on Reddit is not the click. Reddit accounts for about 46.7% of Perplexity top-10 cited sources and about 21.0% of sources inside Google AI Overviews, per SE Ranking and Tinuiti, while Reddit Answers handles about 28M queries a day. When a homeowner asks an assistant "is a 10-year payback normal now?" the reply is largely assembled from threads.
Measurement: 60 days minimum
Average click-to-conversion lag on Reddit is 5.4 days before any solar cycle is layered on. Residential deliberation now spans weeks; commercial runs 6 to 18 months at 5% to 10% lead-to-deal. Reddit Pro reports about 92% pixel attribution accuracy, which is good enough to be useful and not good enough to be the only read.
| Measurement layer | What it answers | Minimum window |
|---|---|---|
| Reddit Pro pixel | Direct conversions and lag | 30 days |
| Branded search volume | Whether awareness moved | 60 days |
| CRM first-touch field | Whether Reddit started deals | One sales cycle |
| Geo holdout | Incrementality vs baseline | 60-90 days |
| Review and thread mentions | Reputation effect | Quarterly |
Budget the test the way you budget brand: year-one solar brand budgets run $25,000 to $80,000, and an established installer spends $100,000 to $300,000 a year. A $3,000 to $8,000 Reddit test sits inside that line, not inside the lead-gen line. The same discipline we apply on growth marketing engagements and measure via data intelligence.
Budget sizing by installer stage
Reddit only makes sense as a slice of brand and research spend. Sized against the brand budgets installers already run, the test is small enough to be honest about.
| Installer stage | Annual brand budget | Sensible Reddit slice | Objective to buy |
|---|---|---|---|
| Year one / single crew | $25,000-$80,000 | $3,000-$6,000 | Objection research and thread presence |
| Regional, multi-crew | $80,000-$150,000 | $8,000-$15,000 | Local subreddit reach plus AI visibility |
| Established $20M installer | $100,000-$300,000 | $15,000-$30,000 | Always-on reputation defence and C&I reach |
| Community solar operator | Programme dependent | $5,000-$12,000 | Subscriber education against $69 per kW |
Two guardrails. Never fund Reddit out of the capture budget that pays for search and Local Services Ads, which close at 15% and above. And never expect the channel to beat referral economics: a $500 to $1,500 referral payout closing at 29.2% is still the best money a solar installer spends. Reddit’s job is to make sure the brand survives the audit that happens between the quote and the signature.
Also budget for the thread that goes wrong. Communities archive complaints permanently, and with 88% of buyers reading reviews, a single unanswered accusation can outrank a paid campaign. Assign a named person to reply, and treat responses as part of media cost - not as customer service overflow.
A 90-day Reddit test for a solar installer
| Phase | Spend | Action | Read |
|---|---|---|---|
| Weeks 1-2 | $0 | Read r/solar and local subs; log the 20 most common objections | Objection list becomes the creative brief |
| Weeks 3-6 | $1,500-$3,000 | Conversation placement answering three objections with real numbers | CTR against the 0.41% benchmark |
| Weeks 7-10 | $1,500-$3,000 | Add local subreddit layer plus a pricing-transparency guide | Cost per assisted lead, not per lead |
| Weeks 11-12 | Hold | Compare branded search and first-touch data against a holdout geo | Incremental lift or stop |
What not to do on Reddit as a solar brand
- Do not run a free-quote offer as the only creative. Aggregator-style offers close at 5% to 10% and read as spam in these communities.
- Do not judge the test on 30-day last click. Lag is 5.4 days before the sales cycle.
- Do not assume organic is a free substitute. 62% of posts get zero comments in 24 hours.
- Do not hide price. Median marketplace price is $2.49 per watt and the community already knows it.
- Do not shift core capture budget. Search and Local Services Ads still close at 15% and above; Reddit supports them. For that cost baseline see our Google Ads pricing guide and the channel comparison in HVAC LinkedIn Ads data.
Frequently Asked Questions
Do Reddit Ads work for solar companies?
Not as a primary lead channel, and yes as a due-diligence channel. Blended Reddit cost per click is about $1.47 against $15 to $50 for commercial solar search clicks, but Reddit users arrive to audit a quote rather than to buy one: with payback stretched to 10.4 years, buyers spend weeks checking price per watt and installer reputation. Campaigns that answer those questions with real numbers - price per watt, degradation, panel brand comparisons - earn cheap presence at the exact moment competing quotes are compared.
What do Reddit Ads cost in 2026?
Traffic campaigns run about $0.20 to $0.80 cost per click on $2 to $6 CPMs, conversion campaigns $0.80 to $1.75 with cost per action of $40 to $120+, and blended CPC sits near $1.47. CPMs are roughly 30% to 50% below Meta for comparable audiences. For a solar advertiser paying $40 to $120 per Google lead and $15 to $50 per commercial search click, Reddit is the cheapest inventory available - which is exactly why measurement discipline matters more here than on search.
Which subreddits matter for solar advertisers?
The purchase-research communities, not the enthusiast ones: r/solar, r/solarDIY, r/energy and the local city and state subreddits where quote screenshots get posted. Subreddit targeting produces about 1.8x the click-through rate of interest targeting, and Conversation Placement ads deliver about a 0.41% CTR - roughly 2.1x home-feed inventory. Local subreddit targeting also matches the way solar is bought, since utility rates and permitting vary by jurisdiction.
How does Reddit affect AI visibility for solar brands?
Substantially. Reddit accounts for about 46.7% of Perplexity's top-10 cited sources and about 21.0% of sources inside Google AI Overviews, and Reddit Answers handles roughly 28M queries a day - about 18% of platform traffic. When a homeowner asks an AI assistant whether an installer is trustworthy or what a fair price per watt is, the answer is often synthesised from Reddit threads. Ads do not create citations, but the traffic and thread activity they drive puts a brand into the corpus that answer engines read.
How should a solar installer measure a Reddit test?
On assisted influence over at least 60 days, never on last click inside 30. Average click-to-conversion lag on Reddit is about 5.4 days before a solar sales cycle is even added, residential deliberation now spans weeks, and commercial runs 6 to 18 months. Use Reddit Pro pixel data - about 92% attribution accuracy - plus branded search volume lift and a first-touch field in the CRM. Budget the test as brand and research spend against the 22% to 28% better close rate that heavily-reviewed installers enjoy.
