Solar panel vendors have been soliciting solar system sales to Sun Prairie residents. You have the right to ask to see their City of Sun Prairie issued vendor permit. Sun Prairie Utilities does not partner with nor endorse any vendors. It has come to our attention that there is a current vendor aggressively approaching Sun Prairie residents, falsely inferring a partnership with SPU and a four percent (4%) expected annual increase in electric costs. The truth is SPU does indeed work with all solar vendors on proper and safe interconnection to our distribution system.
As solar panel costs decrease, residential installations become more economically feasible. SPU recommends acquiring multiple quotes and allowing our utility to assist in evaluating your proposal(s). As stated above, vendors may overstate the future electric cost increases. Currently SPU's kilowatt-hour rates are only 1% higher than 5 years ago and the equivalent of a 2.2% annual increase over the last 25 years. In conjunction, future annual escalations are expected to be in the 1%-2% range.
Sun Prairie Utilities is a strong proponent of renewable generation resources including solar generation. We invite our customers to utilize our solar resources on our website and/or contact our Energy Services Representative for proposal evaluation assistance.
