Plan your roof
by sun & season.
Pick a building, place panels, then test morning, afternoon, evening and night across Andhra Pradesh's seasons. Watch the energy flow from panels to inverter, home, battery and grid — and download the results as a report.

Each month is simulated on its 15th with the season's assumptions, then multiplied by the days in the month.

Assumptions — weather & climate (editable)
Simulated conditions, not live weather. Defaults come from the model's seasonal profile for peninsular India. Changing a value updates every result and the report.
| Season | Representative date | Selected-day sky (%) | Season average sky (%) | Ambient temp. (°C) |

- Sun position: astronomical calculation for the chosen location, date and time (IST).
- Irradiance: clear-sky model × 78% base clearness × the sky factor above.
- Losses: shading (your setting), 3% soiling, 10% wiring & inverter, and temperature at −0.35%/°C above 25 °C cell temperature (NOCT 45 °C).
- Home load: an assumed daily profile for a typical 2–3 BHK home, scaled to the selected building. Battery charge/discharge is limited to 0.5C.

Panel capacity is exact (panels × wattage). Generation is a modeled estimate for the simulated conditions shown — it is not live weather and not measured output. Real generation depends on location, weather, shading, equipment, roof orientation and installation, and is confirmed only by a site survey. Solar panels produce nothing after sunset; at night the home runs on the battery or the grid.
- Drag to rotate, scroll or pinch to zoom, right-drag or two fingers to pan; arrow keys pan when the view is focused.
- Turn on “Show free spots”, then click any roof spot to add or remove a single panel.
- “Reset view” returns the camera; “Reset simulation” restores every setting.
