The PV Watts Calculator

The PV Watts Calculator is an online tool that allows users to input various parameters such as location, system size, and module type to estimate the expected energy output of a solar PV system. Here's how it works:

1. Location Input: Users can enter an address or select a location on the map. The calculator uses this information to determine the solar radiation data specific to that area.
2. System Specifications: Users can define the size of the solar panel system, the tilt angle, and the azimuth angle. These inputs help tailor the energy output estimates to the specific setup.
3. Energy Output Estimation: Based on the inputs, the PV Watts Calculator provides an estimate of the monthly and annual electricity production. This helps users understand how much energy their solar panels can generate over time.
4. Cost Savings Analysis: The tool also offers insights into potential cost savings by comparing the estimated energy production with local electricity rates. This feature is particularly useful for homeowners and businesses looking to assess the financial benefits of installing solar panels.
