App Description

SolarMeter is a solar energy analyzing tool that allows you to calculate, estimate and visualize solar power and energy output of a solar panel at specific location using your iPhone or iPad.

You can't find a better source of energy then sunlight. It is presented in unlimited amount all over the globe, it's free and it has no destructive impact on the environment. If you've ever thought of using sun energy, but had some doubts or questions as "Is my location getting enough sunlight?", "Do I have enough area on my roof to cover my annual energy consumption?", "What side of my roof is more energy effective?", "How much area do I need to cover my energy needs?", "How would my energy bill change after PV system installation?", now you can answer all these question using SolarMeter app for iOS.

Solar Meter helps you to check solar potential of your roof, how much solar power you are getting at your location throughout the year and help to estimate how much energy a photo-voltaic system is able to produce per month.

SolarMeter has following features:
- Real-time solar power calculation based on current location, panel/device orientation and panel/device tilt**
- Solar Power and Energy calculation for different period of time: day, month, year
- Ideal (calculated) and experimental statistical solar data (offline) available
- Sensor based inputs for orientation and tilt
- Automatic current location search using GPS and Network
- Graph/Plot 2D data presentation
- Solar panel efficiency control
- Bill and Saving estimation based on user input (energy monthly or annual consumption).
- Roof tilt angle measurement
- Roof area calculation based on Planimeter* app measurement and roof tilt angle.
- Metric and Imperial units
- area converter in Roof Measurement section when units are changed
