Commercial Solar
Soquel High School
Sandbar was retained to have complete design/build responsibility for this DSA project at a public high school. Sandbar performed and managed the process through DSA submission/backcheck/approval and closeout. During construction, Sandbar self-performed the installation and coordinated with the Inspector of Record (IOR) throughout.
Location: Soquel, California
Completed: December, 2008
Installation Type: Standing Seam Metal Roof with positive attachment across 7 rooftops
System Size: 315kW–1800 175W Suntech modules
Inverters: 3 Solectria 60kW/82kW/82kW, 10 SMA Sunny Boy 5000/6000/7000
Monitoring: Fat Spaniel
Comments/Client Quote: "Well obviously the less money we have to spend on electricity, the more money we can spend in the classroom, as you probably know, the government of the state is proposing mid-year reductions in school funding so this kind of a project, although it isn't going to make up for all of the reductions that we're looking at, it'll help."
Safeway Santa Cruz
The new Santa Cruz Safeway store was built as a representation of Safeway’s commitment to environmental stewardship. The store features multiple renewable energy generation means and numerous efficiency measures as well as other water conservations and reclamation systems.
Location: Santa Cruz, California
Completed: April, 2010
Installation Type: Flat roof, ballasted tilt up racking
System Size: 208 kW
Inverters: 2 PV Powered 100kW PVI-100, 480 VAC Interconnect
Monitoring: Energy Recommerce string level monitoring
The entire project team coordinated and worked well throughout the installation to facilitate a clean and low impact delivery so as to not interrupt active operations at the open store. When the scheduled grid interconnect was performed which required shutdown, it was planned for early morning shutdown so as to minimize the impact of store closure.
The system was installed on schedule and ready for feature at the pre-planned 2010 Earth Day Celebration festivities.
GHWTP
In November 2005 the City adopted the Integrated Water Plan PEIR that recommended proceeding with desalination to address the City’s drought shortfall. One major concern with the project is the large amount of power consumed by a desalination plant, and the associated environmental impacts. Impacts of the large power consumption could be mitigated by investing in energy sources that are “climate-neutral” by not generating carbon dioxide.
Location: Santa Cruz, California
Completed: September, 2008
Installation Type: Standing Metal Seam Roof-Mounted Array
System Size: 128 kW
Number of Modules: 654 Sanyo 195 HIT
Inverters: Solectria - 4 15kW, 1 60kW
Monitoring: Fat Spaniel
Residential Solar
Fonstad Home
This is a LEED Platinum home featured as “Americas 2nd Greenest Home” on PBS. The system was grid tied, with battery backup enabling grid connectivity and net metering while maintaining a stand-alone isolation from the grid at any time. The array was mounted with a reverse tilt on rear roof to maintain “street aesthetics” of this beautifully featured home.
Location: Atherton, California
Completed: November, 2009
Installation Type: 400 year old tile, removed from roof in Italy and delivered to site
System Size: 5.1 kW – 24 Sunpower 215W module
Inverters: 1 SMA 5000 & 2 Sunny Islands for battery charging & inverting
Batteries: 48VDC 1500 AmpHour capacity for complete off-grid capacity
Pantelleria
Project was to provide power to a “dumoso” built in 800 AD located on a remote island in the Mediterranean. The dumoso was previously a productive mill producing locally harvested olive oil and wine by traditional means (without power) and is being converted into a comfortable vacation home with modern conveniences.
Location: Mediterranean Island off Sicily, Italy
Completed: April, 2010
Installation Type: Off-Grid pv solar with battery storage, and generator backup
System Size: 7 kW of solar, 1250 AH battery bank, 10kW LPG generator
Inverter Platform: (2) Outback VFX 3048e FLEXware
Electrical Distribution: 230VAC 50Hz – European standards
