Los Angeles Solar Atlas released

This was released today. This entire report is based upon the Solar Map data that was created for our LA County Solar Map.  It doesn’t get a lot of attention in the report, but that data is the largest, most comprehensive solar model for an area the size of LA County.

Our new version is nearing completion, which will showcase more of the detail of that data.  the current beta site is here:

Announcing the
Los Angeles Solar Atlas

Dear colleagues,

Los Angeles is endowed not only with bountiful sunshine, but also with vast expanses of low-rise urban development that offers valuable siting opportunities for distributedsolar energy generation. As a part of our effort towards advancing renewable energy, the Luskin Center is pleased to present an atlas that describes the geography of the region’s rooftop solar resources. The information may prove useful for economic development planners, solar photovoltaic (PV) installers, utility planners, building owners, public administrators, labor union leadership, and anyone interested in the development of solar power in Los Angeles.


This atlas is organized to help cities and electricity utilities understand their own solar rooftop potential so that they may be better stewards of these resources. Each map presents the geographical distribution of solar potential across neighborhoods and parcels. The maps are accompanied by a description of how the solar potential varies across single- and multi-family residences, commercial and industrial parcels, and non-profit and government parcels since the economic benefits and policy incentives may vary accordingly. Because cost-effectiveness increases with the size of a solar installation, the atlas also presents, for each jurisdiction, the number of potential solar projects by size as well as the total rooftop potential.


The atlas is available on our website at


We invite you to explore and employ this resource. We at the Luskin Center are excited to help facilitate the next phase in the effort toward a more sustainable Los Angeles.
