• Grid Connected Solar Power Systems at LCPS

    LCPS's commitment to improving the school system's environmental impact by installing solar arrays on schools that have undergone energy efficient upgrades, allowing a lower reliance on fossil fuels. 

    Through renewable energy, PV panels composted of photoelectric cells convert light directly into electricity.  This energy flows into an inverter which converts the DC current into AC current, similar to that of the power grid. This solar electricity current can then power all the computers, lights, plug loads in the school. Power comes directly from the solar inverter and any leftover electricity can then feed back into the grid. Each school with a solar array will have a lower electric utility need. If a facility needs more electricity than the grid-conducted solar system produces, that power will simply come from the main power grid of Dominion or Novec. On the other hand, if more energy is produced than what is used, a credit for the surplus electricity will be applied to the electric bill. The links on the right will show real time solar generation for each school listed.  

    LCPS has a goal of installing 25.2 MW- DC of solar arrays across 53 buildings. 

  • JL Simpson MS Project Summary

    LCPS partnered with CMTA Energy Solutionsin 2020 to implement a guaranteed energy savings contract. This included the first LCPS photovoltaic array.  The array will offset 75% of the school's electricity usage! The recently replaced roof made this school a perfect candidate for Loudoun County Public School’s first large solar installation.  Another major objective of this project was the renovation of LED lighting throughout the building. Occupancy sensors installed in strategic locations and dimming controls were added to all instructional and office spaces. Additional project improvements are listed below.

    • 592.5 kW PV Solar Array
    • Full LED Lighting Renovation
    • Controls Retro-Commissioning
    • Transformer Replacement
    • Building Envelope Improvements
    • Refurbish Dedicated Outdoor Air Equipment
    • Water Efficiency Upgrades
    • Bunsen Burner Fuel Conversion to Natural Gas from Propane
    • Utility Meter Elimination
    • Domestic Water Heating Improvements
  • JM Lunsford MS

    In 2013 a photovoltaic array composed of 72 solar panels and a nominal output of 9995 Watts was installed at JM Lunsford MS.  Lunsford also has a solar water heating array composed of 16 solar collectors. The total generation capacity of the on-site renewable energy is estimated to serve only 1% of the total energy used at Lunsford MS. The dashboard provides real-time energy information regarding this solar installation.
