Some of the barn quilts in other counties or states are actually painted directly on the barns. For the Sac County, Iowa project, the decision was made to paint the barn quilts on two 4' x 8' sheets of plywood, then eventually mount the plywood on the barn.
A solar panel is a panel exposed to radiation from the sun, that is used to heat water or, when mounted with solar cells, to produce electricity. 1  The solar panel charges a battery during the day that powers our proprietary light bulbs which automatically come on via a light sensor and timer system at night. The solar panel has high efficiency crystalline solar cells, and is easy to install and completely maintenance free.
A solar photovoltaic (PV) module is an array of cells containing semiconductor materials that, with the help of an inverter, convert solar radiation into direct current electricity that can be used in a home or business. A PV array can be placed on a roof, or it can be mounted on the ground.
