Frequently asked questions

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.

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.

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.

By selling monitoring and Solar Assurance plans on systems they have already installed, typically $10-25 per home per month. The install base is already paid for, so that monthly line is recurring margin on work already done. A 400-system base at $20 per month is $96,000 a year.

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.

Median first response is 23 seconds, with a 90th percentile of 31 seconds, measured across 4,019 first-response intervals with no trimming. That speed holds outside business hours: 55.65% of leads arrive after hours, and 94.4% of those get a reply within 60 seconds versus 94.5% during business hours.

Sol AI supports 18 inverter brands: Enphase, SolarEdge, Tesla, SMA, Fronius, CPS, Sol-Ark, Generac, GoodWe, Sungrow, Huawei, Fox, Solis, Growatt, SolaX, Solarman, SAJ and MaxPower — every one of them lands in the same dashboard and the same Issues queue. See all 18 brands →

Yes — Enphase and SolarEdge are fully supported, alongside every other brand on the wall: connect the portal credential and the fleet shows up in the same dashboard. See the brand wall →

No. Sol AI connects to each inverter manufacturer's cloud platform through its API, using a credential you authorise once per brand. Nothing is installed at a site — no data logger, no gateway, no local network configuration — so bringing the systems you've already installed online is a credential exchange rather than a truck roll.

String-level monitoring reports the output of each individual string of panels rather than only the system total. It matters because a system with one dead string still reports plausible total production and shows no fault, so the failure can persist for months. In one case we documented, a 29 kW system ran with one of three strings disconnected for 22 days while the manufacturer's app showed green — a third of the system's production, missing, that only appeared when output was compared against a weather-adjusted baseline.

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.

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.

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.

Only with safety rails you can audit. Every outgoing message from Rae passes a pre-send safety layer — we call it the guardrail — before it is sent: in a five-week production sample it logged 1,630 interventions, rewrote 49% of messages, and blocked 196 absolute price leaks and 21 premature discounts. The log is readable, which is the only thing that makes the assurance worth anything. Unusual cases still go to a human — 95% of conversations complete without one, and the remaining 5% is where the hard ones live.

Rae ships SMS-first with TCPA compliance built in: consent capture, quiet hours, opt-out handling, and audit logs. Web chat and Messenger are available alongside SMS, and SMS activates as carrier registration clears.

The systems keep producing but nobody is comparing their output against expectation. The homeowner still has the manufacturer's app, which reports what the inverter can see, but no one is watching for the failures that do not announce themselves — a dead string, a failing optimiser, encroaching shade. Because residential monitoring runs through the manufacturer's cloud API, another company can adopt those systems without a site visit.

Modular Intelligence is the company behind Sol AI and Rae, founded by Mujtaba Raza. It was built inside Solar Citizen, a solar installation company operating across 11 cities in Pakistan, and its software has run that company's sales and service end to end for over a year. It is now bringing the platform to US installers, starting in New York.

No. SOL AI ties into your existing inverter, no new hardware required.

Yes. Your inverter needs an internet connection so your data keeps updating.

SOL AI is a monitoring service, not an installer: it makes the solar you already own smarter, whoever put it on your roof, and it never sells you hardware or sends out a crew. Our sister business Solar Citizen does install solar in Pakistan, and SOL AI works the same way whether or not they built your system.

Enphase, SolarEdge, Tesla, SMA, Fronius, CPS, Sol-Ark, Generac, GoodWe, Sungrow, Huawei, Fox, Solis, Growatt, SolaX, Solarman, SAJ and MaxPower — every one of them lands in the same dashboard and the same Issues queue.

Not at all. You just connect your existing inverter to SOL AI. No new device, and no installation visit.

For homeowners in Pakistan, pricing is based on your system size (in kWh) — see the Pricing section on the Pakistan home page. US and international installers are quoted per fleet after a short call, since it depends on how many systems or sites you look after and which brands are on them.

For systems above 1000 kWh we offer custom pricing. Just request a quote from the Pricing section or the Contact page.

Yes. You get instant WhatsApp alerts for faults, inverter offline warnings, and grid/battery switches, right where you already chat.

Yes. You get a full breakdown of battery charge, grid import/export, and solar, tracked live and over time.

Yes. You can monitor multiple plants from a single dashboard, each with its own live data, reports, and alerts.

They are estimates derived from your inverter and are meant for guidance. They may differ slightly from your official utility bill.

Your data travels over encrypted connections, and only you can see your plant's data. We never sell your personal data or share it with third parties, and it is used for one thing: running your monitoring.

SOL AI works on any phone or computer browser, and your daily report and alerts arrive on WhatsApp, no separate app to keep checking.

Yes, anytime. No long-term contract, it's a simple monthly plan that stays active until the end of your billing period.
