Solar Data Summarized to 2010 Parcels

solar_mapWith the release of the Local Roll to the public (see this data entry) we are now able to release the dataset that supports the LA County Solar Map (http://solarmap.lacounty.gov).

The Solar Map Database contains the results of the 2006 solar model (for details see this data portal entry), summarized to show rooftop potential for every property in the County.

The solar model itself is from 2006, while the parcel boundaries in this file are from 2010.

Important Note.  The shapefile includes 4 fields that are summaries of the solar potential:

  1. Rank 1 – Square feet of roof receiving excellent solar input (> 1.4 million wattHours per square meter)
  2. Rank 2 – square feet of roof receiving good solar input (1.15 – 1.4 million wH/meter squared)
  3. Rank 3 – square feet of roof receiving poor solar input (950,000 – 1.15 million wH/meter squared)
  4. Rank 4 – square feet of roof receiving negligible solar input (< 950,000 million wH/meter squared)

In the Excel files, we add Rank1 and Rank2 square footage to get the optimal roof area.

How did we determine these ranks?  Download our payback calculations

Organization

solar_formatThe download file organized into 4 folders (see image on right):

  1. Access – an Access database
  2. excel – Excel files – one for each city
  3. Samples – a couple of sample files
  4. shapes – the GIS shapefiles of the database
