Project summary
Shea Home builders were in the process of a new development when the western energy crisis hit California in 2000. In some cases, San Diego Gas and Electric utility bills nearly tripled in one month resulting in a very strong market for high efficiency homes. 306 single-family homes were built. All have solar hot water systems. Still at this point PV was not a standard feature in the development and was offered on only 100 residences.

Urban scale PV aspects
The Shea development is a typical upper middle class residential design for the State of California. The builder worked directly with the manufacturer and yet mounting on the barrel tile roofs was still an issue. The development layout had already been established prior to the inclusion of the solar options and because of the aesthetically desirable broken roofline, only south exposure orientations were considered for solar orientation. Later developments found the broken roofline to be an asset and that varied orientation of distributed generation helped with the utility’s afternoon peak.

Special PV project info
PV architecture and building integration
Urban planning issues
Economical and financial issuesAt the time of the Shea development, California offered $3.50 per watt for PV installations and towards the solar hot water heart. There were no Federal tax credits available at this time.
PV ownershipBuilding owner: Inhabitant. PV owner: Inhabitant. PV energy user: Inhabitant.
Tariffs and metering
Info on grid issuesStandard grid interconnection was not yet well established in California at the time of this development. Input from the builder and the San Diego Regional Energy Office helped develop the standardization of PV interconnection as a result of this project.
Other infoThe Shea homes development was the ice breaker for both high performance homes and homes with a standard PV system. The builder discovered that the solar homes sold first and that even the non PV home purchases had some causal effect due to the “solar Community”
Remarks and recommended readingEnergy yield is 1988 kWh per system.
