Onboarding agent
Starts watching a new site the day it's switched on.
The day a site comes online, the Onboarding agent starts reading it. By the end of the first week it knows what that site should make in its own weather.

Your agents
Four agents. One job each.
They don't replace your team. They do the reading your team never has time for, so people spend their day on the sites that need them.
And your customers get one too: an agent that answers their questions about their own system on WhatsApp, day and night. Read-only, nothing to install.
Performance agent
Every night, checks every site and string against what it should have made.
Every night it compares every site against what it should have produced that day — down to each string (a row of panels wired together) where the inverter reports them. It prices each problem — “losing $28 a day” — and puts the most expensive first.
Losing $28 a dayCase agent
Owns each problem until the site proves it's producing again.
Each problem gets a case, and the Case agent keeps it open after the repair visit. It closes only when the site's own production shows the fix worked — “Fixed ✓ verified”.
Fixed ✓ verifiedCustomer agent
Answers the plant owner's questions on WhatsApp, 24/7.
It answers the owner's questions about their own system on WhatsApp, any hour, from live plant data, and sends alerts and reports on the same thread. Like an engineer on call for every plant, all day, every day.

And that's only the repair engine — Solar AssuranceSolar AssuranceA simple monthly plan — $10–25 — you sell to homeowners. It means: someone is actually watching my solar system. We do the watching, you get the service call, and your brand is on every report — and most of that monthly line is yours.Customers who feel looked after renew, refer their neighbors — and hand you a closing line the other bid doesn't have: “every system we install is watched for its lifetime.” subscriptions add their own line.

When something breaks
Every app showed green. A third of the system was dead for 22 days.
This really happened: a 29-kilowatt home system with one of its 3 strings disconnected. The manufacturer's app stayed green — the total still looked believable. Sol AI knew what the system should be producing, saw the gap, and flagged it on its own. This is what that moment looks like:

Each diagnosis carries a confidence score and an estimated monthly cost, and closes with a recorded inspection outcome — confirmed, false positive, or fixed.
In production
Real systems, one dashboard.
Residential rooftops to commercial arrays, across every supported brand — if it feeds an inverter, Sol AI reads it. These are real systems the platform watches today.
How it works
Six portals in. One answer out.
Every system you've installed already sends its data to a manufacturer's cloud. Sol AI reads all of them at once, works out what every system should be producing, and tells you — and your customer — only what matters.

We connect each brand's cloud, import your history, and train your team. Supported brands connect in days; our target for everything you've installed is inside 30.
Sol AI starts watching
Every system checked around every 11 minutes against what it should be producing. Faults surface with a name, a priority, and a plain-English explanation.
You make the calls
Fix the faults — you bill the truck roll and repair. And on every call, offer Solar Assurance at $10–25/month. We hand you the sales kit: email and SMS templates that sell it for you.
The revenue compounds
Assurance subscriptions, repair jobs, and the referrals that watched customers send — all from systems you had already installed.
Work with us
Put every system you've installed on one screen.
Our team does the whole setup: every inverter brand you've installed in one dashboard, historical baselines imported, your team trained, onboarding led by the founder. Tell us about your fleet and we'll come back within a day.
Why now
The market just changed shape.
Installs are down ~15% in 2026.
The federal tax credit for purchased home systems expired. Survivors have to cut labor cost now.
The installed base only grows.
5M+ US solar homes need watching for 25 years, and that number rises every year even in a down market.
Orphaned systems are everywhere.
When an installer goes out of business, their customers are left with no one watching. Whoever can read whatever brand is on the roof inherits those customers.
Two products, one platform
One keeps your customers. One signs new ones.
Sol AI

Sol AI knows what each system should be producing and says so when one falls short, with an estimated cost attached and the homeowner told in plain language. Turn your install base into $10–25/month Solar Assurance plans.

FAQ
Questions, answered
What is Sol AI?
Sol AI is a team of AI agents for a solar fleet. An Onboarding agent starts watching each new site the day it's switched on; a Performance agent checks every site and string every night and prices each problem in dollars a day; a Case agent keeps each problem open until the site's own output proves the fix worked; and a Customer agent answers the owner's questions on WhatsApp. Underneath is a digital twin — a live model — of every system, across every supported inverter brand, in one dashboard. Because the model knows what each system should be producing under today's weather, Sol AI can flag the gap when real output falls short, classify the fault with an estimated dollar cost, and explain it to homeowners in plain language. It currently watches 636 systems totalling 21 MW — 399 of them installed by other companies — checked roughly every 11 minutes.
What is a Solar Assurance plan?
A monthly service an installer sells to homeowners — typically $10–25/month — that says: someone is actually watching your system. Sol AI does the watching, checking each system roughly every 11 minutes against what it should be producing; the report carries the installer's brand, and the homeowner is told in plain language when something needs attention. Most of that monthly line is the installer's service revenue, and the customer relationship stays the installer's.
How do solar installers make money from repair and maintenance work with Sol AI?
Monitoring finds the faults, and every fault is a customer call: you tell the homeowner what's wrong, they ask you to fix it, and you bill the truck roll plus the repair at your own rates. Sol AI finds the work and takes no cut of the service revenue. What it adds up to depends on how many systems you've installed, your fault rate and your market's prices — the service calculator on our homepage lets you do the math with your own numbers.
What is Rae?
Rae is an AI sales agent for solar companies. It answers inbound leads in a median of 23 seconds around the clock, reads electricity-bill photos, transcribes voice notes, sizes the system, negotiates inside hard-coded guardrails, and delivers a proposal in a median of 7 minutes. It has handled 4,198 real leads in production.
What access does Sol AI need — and can it control my customers' systems?
Sol AI reads production data through each inverter manufacturer's own cloud service, using a credential you authorise once per brand. That access is read-only: Sol AI watches output; it cannot send commands to an inverter, change its settings, or switch anything on or off. Revoke a credential in the manufacturer's portal at any time and the data flow stops with it.
How does Sol AI handle my customers' data?
Sol AI stores what monitoring needs: production and device readings, system details, and the contact information you choose to add for reports. Data travels over encrypted connections, is never sold or shared with third parties, and is used for one thing — running your monitoring. Data is hosted on AWS. Read-only access to your monitoring portals; nothing is installed on site.
Is Sol AI SOC 2 certified?
Not yet — we're a young company and would rather say so than imply otherwise. An independent security review is part of our US launch and SOC 2 certification is on the roadmap. What exists today: authorised, revocable, read-only vendor credentials, and an AI safety layer whose intervention log you can read. We put our current security posture in writing at the pilot-agreement stage, and we answer diligence questions directly.
