SolarPanel: Roof Tilt lets you drag a panel, raise a chimney and watch the sun sweep past, all on a roof canvas that works with zero signal. Try the live demo below.
Drag the panel from 0 to 90 degrees and see the sun trajectory react instantly on a visual 2D roof.
Drop trees, chimneys and parapets, then read the exact shadow length they throw in every season.
Get ideal tilt for winter, summer or year-round yield, based on your latitude.
See the percentage drop when partial shade creeps across a photovoltaic string.
Turn total panel wattage and peak sun hours into expected daily kWh.
Keep an offline log of panel specs, inverter limits and roof array layouts.
☀️ We are a small team of solar enthusiasts and app builders who got tired of squinting at sun charts on rooftops. SolarPanel: Roof Tilt is our answer for installers, homeowners, off-grid DIYers and RV travelers.
🧭 Our mission is simple: turn tricky solar geometry into a calm, visual routine that anyone can follow, even on a remote roof with no cell signal.
🔋 You get a draggable roof canvas, seasonal sun arcs, shadow loss percentages, ideal tilt angles and a daily kWh estimate, plus an offline vault for every array you plan.
🏠 That matters because a few degrees or one stubborn chimney can decide whether a system sings or sulks. Know before you drill, and save energy, time and money.
Tilt smart. Shade less. Shine more.
SolarPanel: Roof Tilt does not collect, store or share any data. Everything works locally on your device.
None. We do not gather personal details, location, device identifiers or usage records. The latitude you enter for calculations is used only on screen.
Since nothing is collected, nothing is used, analyzed, profiled or sold. Your panel specs and roof layouts are processed only to display results to you.
Saved projects in the String Vault stay in the app's local storage on your device. There is no cloud, no server and no sync.
The app includes no analytics, advertising networks, trackers or social plug-ins, and it needs no internet connection to work.
Because your data never leaves your device, it is protected by your device's own security, such as its passcode and encryption.
We collect nothing from anyone, including children under 13, so the app is consistent with COPPA principles and is safe for family use.
You are in charge. There are no accounts to create. Uninstalling the app deletes all saved projects from your device.
If this policy changes, we will post the updated version here with a new effective date. Our commitment to collecting nothing will remain.
