Solar Plant Summaries for School Sites

  • Production and Performance Reports are available for all PUSD sites, see links below.  These reports show the budgeted or projected amount of energy produced by each site’s solar arrays, the actual energy production, and the percentage of Production vs. Budgeted Amount, in kWh. These reports show from the first year of operation, through either February, 2017 or June, 2017. 

    A kWh (kilowatt hour) is a measure of how much energy is used. It does not mean how many kilowatts are used in an hour; rather, it is simply a unit of measure that equals the amount of energy used, if you kept a 1,000 watt appliance or lightbulb running for an hour.  For instance, a 100 watt lightbulb would take 10 hours to use one kWh of energy.  It is also approximately the same as running a refrigerator for about three hours, a laptop all day, or cooking in a 2,000 watt oven for half an hour. For perspective, a small family living in a three-bedroom house with two spouses working and children in school might use close to 11,000 kWh a year. 

    To give you perspective of energy use at a home versus at a school, at Foothill Elementary School, the solar arrays at the site produced more than 468,000 kWh in actual energy in 2012. That is enough energy to power more than 42 homes in a year!
