The Master Gardeners are interested in adding rooftop solar PVs to the garden shed to the east of the Idea Garden in the Arboretum. The Idea Garden is a community garden planned, managed and maintained by the Champaign County Master Gardener volunteers.

The accompanying map shows the layout of the garden, The solar panels would be installed at shed (A) and provide power to building. The power grid would be extended to the garden to power light fixtures and outlets at sites B1-B4, C and D. Remodeling of the Idea Garden to provide access for people with disabilities is scheduled to begin in 2016, so this would be an opportune time to install underground cables. A small parking lot is also to be built at D. Funding for the proposed installation is not available from the grant supporting the remodel.

The Idea Garden committee, with the UI Extension, continues discussions about adding rooftop solar to the Arboretum Garden Shed hear the Idea Garden.  Last year, Idea Garden representatives worked with Masters of Energy Systems students to consider potential design plans.  The final scope of the desired solar PV project is still to be determined. One likely option is to use solar to power the light in the shed, and use the existing campus electrical grid to provide other power needs, such as winter heating.

The Architecture Review Committee (ARC) approved the concept for rooftop solar on the Idea Garden shed, per this description from F&S Engineer Kristine Chalifoux: "Engineering Design has been approached by the Illinois Extension about designing solar panels for the roof of the shed at the arboretum.  They would like to cover the room with panels and use batteries in the shed to store the power.  They would like to have a light on site, ability to use power tools, and possibly some heat during the winter.

The panels would be approximately (depending on manufacturer) 3’x5’ and cover the entire south facing portion of the roof.  The roof has two slopes with a shallower slope at the front.  Both would be covered."

ARC approved the request and concept of installing the solar panels on the roof of the shed providing that the integrity of the shed could support the installation.
