Prescott Public Library first installed solar panels in September of 2009. The array utilizes inverters with each panel, allowing for easy expansion of the system. With donations from Prescott residents the size of the rooftop solar array was expanded from its original 63 panels to the current 85 panels. PPL uses solar panels to provide a portion of the power to the building. Monitor the library’s solar panel power production.
In 2018, City of Prescott Water Resource Management and Prescott Public Library staff teamed up to revitalize the library’s rain barrel and put rainwater harvesting into action. When it rains, we harvest rainwater from the library roof and store it in a 1000-gallon cistern located near the courtyard. Library staff uses rainwater from the cistern to support an educational garden and provide hands-on nature learning opportunities for the community.
Why we collect rainwater:
- Rainwater is naturally softened and is great for plants!
- It helps protect watersheds by slowing runoff and reducing impurities into local streams and reservoirs like Granite Creek and Watson Lake.
- It reduces the need for municipal (City) water on outdoor landscaping and saves money by lowering water bills.
Water Bottle Filling Stations
Water bottle filling stations are on the 1st and 2nd floors of the library near the elevator. Each station is mounted just above the drinking fountains on each floor. These filling stations deliver clean and quick water bottle fill up to help minimize dependency on disposable plastic water bottles. The stations feature touchless, sensor activation for ease of use and a clean, sanitary fill as well as an automatic 20-second shut-off timer. Each station has a Green Ticker which counts the number of 20 oz. plastic water bottles saved from waste.
