US-based Solar Topps has signed a new solar panel supply agreement with a panel manufacturer Schott Solar.

Solar Topps will install Schott’s solar panels on upcoming commercial solar power installations that range from 30kW to 200kW.

Solar Topps will deploy solar panels for car dealerships, hotels, strip mall shopping centers, convenience stores, freight forwarding companies, import/export winter produce warehouse facilities and several multi-unit franchisees located in Tucson, Nogales, Yuma, Tempe and Phoenix, Arizona.

During last month, Solar Topps marketing campaigns targeted Arizona commercial building owners with an unmatched offer of $4 per watt installation cost, the company said.

Solar Topps intends to install 4MW by the end of this year, and the federal solar grant program is expected to end at the end of December 2011.
