Generating Electricity to Reduce Utility Bills and Emissions

(User-friendly URL: This webpage can be reached at www.charlottesville.org/citysolar)

 

The City of Charlottesville has solar photovoltaic (PV) systems installed on City maintained facilities with more planned for installation. Each system has a data monitor that tracks most, if not all of, the system’s energy production.

The first three systems installed represent different scales of solar power generation with a medium-large array (Charlottesville High School), a small-medium array (City Facilities Maintenance Building), and a residential-sized scale (ecoREMOD Energy House). Completed in late 2016, the Smith Fitness & Aquatic Center is the newest one in the City's portfolio. As more systems come online, they will be added to our data tracking.

Performance data from the systems are provided below and roll up numbers will be updated periodically. This data can be used as a starting point for residential and non-residential properties considering the benefits of solar power, the potential generation capacity, and the potential for monthly reductions on utility bills.

Individual Solar Facilities Data

 

Charlottesville High School (CHS) – The CHS project has two parts totaling over 100 kW of power potential: a stationary rooftop panel array and two ground pole-mounted arrays that track the sun’s movement across the sky. Energy production information below represents 112 kW of the rooftop and pole-mounted arrays. This solar PV system is expected to provide about 1/8 of CHS’s annual electricity usage.

Facilities Maintenance (FM) Building – The FM building’s 20 kW solar array is oriented due south and is mounted on the roof. The array is expected to provide over ½ of the building’s expected annual electricity usage.

ecoREMOD Energy House – The ecoREMOD Energy House project renovation included both a residential sized solar PV system and a solar thermal system. The solar thermal system heats the water used for showers, washing machines, and other household potable uses. The solar PV system provides electricity for the house. Since coming online, ecoREMOD has been mostly used as office space. Monthly electricity bills are often in the single digits.

Fontaine Fire Station – The Fontaine Fire Station solar PV system was completed in early 2016. The system is 17.7 kW.

Buford Greenhouse Off-Grid Solar System – A small completely off-grid solar PV system was installed at Buford Middle School in 2014 to power the ventilation fans for the greenhouse. The system has 3 pole mounted solar PV panels totaling 390 watts attached to batteries with a storage capacity of 4,176 watts. The system powers the greenhouse's two ventilation fans (16” 12v DC) and a small 375w DC to AC inverter to provide 120v AC for small additional loads (such as a laptop, radio, or cordless tool battery charger).
