Built by a solar owner,
for solar owners.

After installing solar panels, we asked the same questions every prosumer asks: Is my system performing as it should? Should I run the dishwasher now or wait? Are my panels degrading without me knowing?

The existing apps told us what happened yesterday. We needed to know what happens tomorrow — in time to act.

"We got tired of guessing. So we built the intelligence we wished existed from day one."

Three pillars.
One intelligent forecast.

☀️

Sol

Solar Data

Real-time irradiance, cloud cover, temperature and sun angle — retrieved for the exact GPS coordinates of your panels. Not your city. Your panels.

👁️

Vis

Forward Vision

48-hour rolling forecast with hourly resolution. See your production curve before it happens. Decide when to run the laundry, charge the EV, or defer to the grid.

🧠

IQ

System Intelligence

The algorithm learns your panel's real behaviour — shading patterns, seasonal drift, calibration from actual production data. Gets sharper every day.

Everything your solar investment needs.

From real-time monitoring to long-term ROI — all in your pocket, all offline-capable.

Real-time Inverter Monitoring

Connect to Fronius, Huawei FusionSolar, Growatt, Deye, SunGrow, Solis, SMA and more via cloud API or direct local Modbus TCP. See live power, battery SOC, grid flow.

📈

Smart Production Forecast

AI-powered 48h forecast with hourly bars, cloud cover overlay, and SolGrad colour scale. Instantly see if tomorrow is a good day to run your heavy appliances.

💰

Financial Analysis & ROI

Track daily and cumulative savings, compute break-even year, simulate energy price scenarios and visualise your investment payback with the interactive ROI calculator.

📅

Production History Calendar

Monthly and weekly view of actual vs. forecast production. Enter real kWh readings to auto-calibrate the prediction algorithm for your specific installation.

🌱

CO₂ Avoided Tracking

Quantify the environmental impact of your system. See kilograms of CO₂ avoided today, this month, this year, and since installation. Earn Green Leaf tier badges.

🔌

Smart Appliance Recommendations

SolVisIQ tells you which appliances to run right now based on your real-time solar surplus. Washing machine, dishwasher, EV charger — automatically timed to free energy.

Sol·Guard — WAS Series

14 advanced features.
None like these anywhere else.

Sol·Guard is SolVisIQ's engine of applied intelligence — a set of algorithms that solve the real problems solar owners face every day. Each WAS (What Actually Solves) feature is built from a genuine user pain point.

🔴 Critical — Active Protection
Grid Voltage Guard
WAS-01
Live

Estimates grid voltage in real time using your production level and peak-hour factors. Alerts you before your inverter auto-disconnects at 253V — before you lose production and don't even know why.

Negative Price Alert
WAS-02
Live

Monitors ENTSO-E spot prices. When prices go negative, you're paying to export. SolVisIQ alerts you and recommends: stop injection, defer load, or charge the battery instead.

System Health Check
WAS-03
Live

Detects gradual panel degradation by comparing expected vs. actual production over time — corrected for temperature and cloud conditions. Catches a 15% efficiency drop you'd never notice otherwise.

⚡ Optimization — Smart Energy Use
Battery Brain
WAS-07
Live

Analyses solar forecast and home consumption to recommend the optimal charge/discharge strategy for your battery — factoring in grid tariffs and battery health to maximise self-consumption.

LocalConnect — Modbus TCP
WAS-09
Live

Direct Modbus TCP connection to your inverter — no cloud account needed. Reads live PV power, battery SOC, grid flow, and AC voltage every 30 seconds on your local network.

Solar Drive — EV Smart Charging
WAS-14
Live

Controls your OCPP 1.6 charging station to schedule EV charging exactly when solar surplus is highest. Free miles from your own roof, automatically. Compatible with Easee, Zaptec, ABB Terra, Wallbox and more.

Shadow Mapper
WAS-05
Live

Auto-learns your panel's shading patterns from the first day. Adjusts hourly production expectations based on recurring shadow events — chimneys, trees, neighbouring buildings — no manual input needed.

🔮 Intelligence — Simulation & Insight
Upgrade Simulator — Future Solar
WAS-10
Live

Simulate adding panels or a battery to your system. See projected annual kWh gain, additional annual savings, and estimated payback period — before you spend a euro on hardware.

Carbon Score
WAS-12
Live

Tracks CO₂ avoided compared to grid average (0.294 kg/kWh). Earn tier badges as your system grows greener — from Bronze to Gold to Platinum. See impact today, monthly, yearly, or since install.

Seasonal Lens
WAS-13
Live

Analyses monthly production patterns from PVGIS and your real data to surface seasonal peaks and valleys. Know which months to maximise usage and when to plan maintenance.

Precision Beam — Satellite Nowcasting
WAS-04
Live

Integrates Solcast satellite data for high-precision solar forecasts — detecting cloud movement within minutes. Up to 10 free requests per day with your Solcast API key.

Point & Configure — Gyroscope Azimuth
WAS-08
Live

Point your phone at your panels and tap Calibrate. The magnetometer reads the exact compass direction and stores your azimuth automatically — no guessing, no manual lookup, more accurate forecasts.

Lock Screen Production — iOS Live Activities
WAS-06
Sept 2026

See live PV power output on your iPhone lock screen and Dynamic Island — without opening the app. Glance at your production the moment you pick up your phone.

Built different.
By design.

We ship what you need.

SolVisIQ is a living product built with real solar owners. Every Sol·Guard feature started as a user message. We read every one, and when something solves a real problem — it ships.

1
You encounter a real problem

Your inverter disconnects on sunny days. Energy prices go negative and you don't know. Panels produce less than expected but you can't tell if it's weather or degradation.

2
You tell us

Send an email, leave a review, or use the in-app feedback. No feature request form, no ticket system — just a direct line to the people who build this.

3
We build it

If your problem is real and solvable, it becomes a WAS feature — with an algorithm designed specifically for it. Not a workaround. An actual solution.

4
Everyone benefits

The feature ships in the next update for all 26 language markets. One user's frustration becomes a tool for thousands of prosumers worldwide.

What's live. What's coming.

Transparent about where we are. Everything marked "Coming Sept 2026" is in active development.
