PVMapper can help you design, analyze and develop your next solar plant.

Innovative technology that helps you to create your perfect solar site Check out our free web application and site designer.


PVMapper is a utility-scale solar site mapping web application that is open-source and free to use. It is a geographical information system (GIS) with an easy-to-use interface that provides end users with specific information and capabilities relevant to siting large solar energy projects. In addition to these mapping functions, PVMapper has added an independent site comparison capability.


Easily customizable as well as built on existing open source technologies such as OpenLayers, jQuery, Ext JS and MongoDB.

Plug-in Architecture

All decision making/scoring tools are developed as plugins which gives the ease of customizing or adding new scoring tools.

Multiple Scoring Function

Each scoring tool has built-in scoring functions that can be reconfigured on-the-fly to suit an end user's individual needs. In addition, the weighting system can be easily adjusted, changing the amount that each tool affects a site's overall score.

Social Aspect

Includes measures of social preferences based on responses from multiple surveys.

Data Sources

PVMapper integrates data from approximately 30 publicly-available sources, consistent with its open-source configuration.  These datasets are served from national laboratories, open-source collaborations, and federal departments and agencies.

PVMapper Site Designer

PVMapper Site Designer is the desktop extension of the PVMapper online application. It is a free tool for designing and analyzing a specific site and evaluating the amount of power that can be produced from that site. It can be used for designing large scale photovoltaic (PV) systems based on numerous factors to reflect the characteristics of landscape specific to the area including site location, time zone, sun path, nearby weather station data, tilt and azimuth angle of the solar panels, and nearby objects such as trees and buildings that may obstruct or cast shadows over the panels.

Assesses Solar Shade

It takes into account nearby objects such as trees and buildings that could reduce the efficiency of the layout design.

Power Production

Uses the NREL's System Advisor Model along with data from nearby weather stations to compute potential power production of a layout.

GIS Compatible

Users can easily import Esri shapefiles to include data such as weather stations, buildings, DEM, etc.

3D Visualization

PVMSD uses the panel location data to create a PV panel array as a polygon shapefile and a Collada file that can be used in SketchUp to visualize the grid in 3D.

PVMapper has everything you need to get started on your solar site.


Together we are creating designing exploring a better world.
