richmond solar power potential map

Outcomes and Conclusions

The solar power potential map provides useful information the City can use as it tries to increase the community’s solar energy production. The map visually illustrates the feasibility and suitability of adding solar panels across town by identifying the roof’s slope, orientation, and estimated solar radiation per building. For example, the larger roofs in suburban areas had more solar generation potential than those in urban areas because of roof size.

Overall, this project was inexpensive and easily reproduceable. The City of Richmond is excited for the platform to assist neighborhoods transitioning from fossil-fuels to on-site solar energy as a method for reducing greenhouse gas emissions community-wide. The City intends to publish the solar map and conduct a press release to inform property owners about their solar potential.


The map developer reflected that there were few technical challenges throughout the project. Internet connectivity issues sometimes caused tools to crash and the program to restart, delaying processing time.

Staff also found that while the instructions from the ArcGIS lesson were intuitive enough, previous GIS experience was helpful to replicate the project for the Richmond community. Furthermore, the project can be more or less difficult depending on the amount of detail, geographical scale, and size of the area being analyzed.

Takeaway Message

Matt Evans, the GIS Coordinator for the City of Richmond, gave the following advice:

"This data provides powerful insight for our local government and individual property owners to better understand the possible solar energy production on rooftops across Richmond. This process is reproducible across Indiana thanks to easily accessible statewide GIS data and should be usable by many communities with GIS capabilities.”
