Solar
SRVUSD is proud of its initiative to construct and operate solar arrays in the parking lots of five schools (Phase 1) in the District: California High School (CHS), Dougherty Valley High School (DVHS), Monte Vista High School (MVHS), San Ramon Valley High School (SRVHS), and Diablo Vista Middle School (DVMS). These five systems are comprised of more than 10,000 panels. The systems, by contract, began converting solar energy to electricity at these schools starting October 1, 2011. Gale Ranch Middle School (GRMS) was added in 2012.
December 2015 - At its December 8, 2015 meeting, the Board of Education authorized staff to execute an agreement with SunPower Corporation for photovoltaic systems at up to 16 additional school sites (Phase 2). The project is financed using Clean Renewable Energy Bonds.
PHASE 1
- First 5 schools completed in 2011
- First Year Expected Output: 6.2 million kWh/year overall at 5 schools:
- CHS, DVHS, MVHS, SRVH, DVMS
- Gale Ranch was added in 2012 (fixed tilt)
- Over 10,000 panels district-wide. SunPower panels are the most efficient in the world at converting solar energy to electricity

- If actual performance is less than the adjusted expected performance, SunPower will pay the district for lost savings based on historical rates – as well as lost utility rebates.
- Warranties
- Solar panels have 25 year warranties
- Inverters have 20 year warranties
- Maintenance agreement for 17 years included in price
- The height of the support structures range from 12 feet to 18 feet high, with the tracker systems mounted on top. Gale Ranch is fixed tilt
- The project has been reviewed and approved by the Division of State Architect as well as the local and State Fire Marshals. Notification requirements under the California Environmental Quality Act (CEQA) have been met.
FAQS RELATED TO DISTRICT'S PH1 SOLAR INITIATIVE
Q: What is the San Ramon Valley Unified School District’s current Solar Project?
A: SRVUSD is in the final stages of constructing solar arrays in the parking lots of five schools in the District: California High School, Dougherty Valley High School, Monte Vista High School, San Ramon Valley High School and Diablo Vista Middle School. These five systems are comprised of more than 10,000 panels. The systems, by contract, begin converting solar energy to electricity at these schools starting October 1, 2011.

Q: How is the project being funded?
A: The Federal government, as part of its most recent stimulus program established the “Qualified School Construction Bond Program.” SRVUSD applied for and was approved to receive $25 million in QSCBs through this program. Essentially this is a near 0% interest loan to the District that is paid off through the energy savings realized by the systems.

Q: What is the cost to the school district?
A: There is no net cost to the district because the monthly energy savings are being applied to the debt service. In approximately 16 years the bonds will be paid off and the District will begin realizing an estimated $3-5 million per year in energy savings to the District’s General Fund Budget.

Q: Why would the SRVUSD consider incurring so much debt with the budget problems we are facing?
A: Financial consultants have analyzed the solar project and determined that it will provide significant cost savings, actually freeing up significant funds for direct support of students and schools. After 25 years, the cumulative savings (after the debt is paid) is expected to exceed $23 million. The District will be paying for the solar panels with rebates and savings on electricity.

Q: How were these Qualified Construction Bonds to be used?
A: They were intended to create jobs through approved construction projects. The Board of Education decided that the money should be used for solar as it would generate savings to pay back the loan and create on-going savings to the district. The Board and staff also believed it was important for the school district to model environmental stewardship and energy conservation for students and the community.

Q: Why doesn't the District use the $25 million on other things like improving facilities, or hiring more teachers?
A: The $25 million in Qualified School Construction Bonds (QSCBs) has to be repaid, so it must be spent on a revenue generating project. The funds cannot be used to hire teachers or expand programs; they are intended to help stimulate the economy through job creation within the construction industry.

Q: Why didn’t the District wait a few years to see if solar gets less expensive and/or more efficient?
A: This bond was only available for a limited time, and it was doubtful that similar bonds or stimulus funds would be available in the future. Also, currently the PG&E rebates for solar energy are generous and the price of solar panels is relatively low because of the economy. Installation costs have also been falling due to the economic downturn. The district felt this was the opportune time to take advantage of the program as there are no guarantees that this favorable combination will last.

A: Many districts in California are turning to solar energy, including Milpitas, San Jose, San Mateo, San Diego, Los Angeles, Oxnard and Mt. Diablo school districts.
Q: Why did the District choose to place the panels on parking arrays rather than rooftops?
A: A number of the schools' roofs are not oriented well for solar panels. There are also issues about the ages of the roofs and concerns about penetrating the roofs to anchor the solar panels. Parking lot structures have the added benefit of using automated panels that rotate with the sun to maximize exposure, as well as shaded parking and better lighting at night.

Q: Is the District also looking into other energy conservation strategies?
A: Yes. The District currently budgets $3.3 million annually for electricity. The District is exploring additional strategies including retrofitting with low energy-use bulbs and equipment, implementing centralized set points for heating and cooling, and remote monitoring and control systems. The district is also promoting “conservation as human behavior” as the most significant factor in energy conservation and energy savings.

Q: Is the district looking to expand the project?
A: The district is looking into the possibility of combining the remaining unused QSCB funds (@ $700,000) with the anticipated first-year savings associated with the five operational systems to provide solar at one additional school. Gale Ranch Middle School was originally considered as part of a six-school solar project, and has both the space and sun exposure capacity. The district is exploring this option, but no decision has been made.
