# Solar energy estimator

Canonical page: https://nepocore.com/tools/solar-energy/

Estimate daily and monthly output from panel capacity, sun hours and losses. This browser tool shows the inputs, assumptions and resulting output so you can use it for a specific everyday task.

## How to use it

1. Enter your own values or choose a supported file.
2. Adjust the options and run the tool.
3. Review the result, then copy, export or save it when available.

## Example

Explore a 3 kW array with four peak sun hours per day and a chosen performance ratio.

## Limits and checks

Sun hours, shading and losses are entered assumptions. This is not a location-specific generation forecast or electrical installation design.

## Access and processing

Free to use without an account. Interactive processing requires JavaScript in a modern browser. Input is processed in the browser rather than sent to a processing server. Optional browser storage is not a synchronized account.
