Yes! Solar, Inc. Introduces Revolutionary New Solar Residential Installation System

October 14, 2008

Yes! MosaicTM Energy Series Systems Allow Homeowners to Rapidly Take Advantage of New 30-Percent Federal Investment Tax Credit and Energy Independence ROSEVILLE, Calif.--(BUSINESS WIRE)--Yes! Solar, Inc., a wholly owned subsidiary of Solar Power, Inc. (OTCBB:SOPW) announced today that it has introduced a new solar module racking system that will be the backbone of its Yes! MosaicTM residential photovoltaic (PV) solar home energy systems - each Yes! Mosaic™ system is sized to the precise electrical energy requirements of the homeowner. The proprietary new racking system, ClickRackTM, utilizes a revolutionary new low-profile mounting system that dramatically reduces installation times while providing an extremely secure and aesthetically superior finish, regardless of roof style or architectural requirements. ClickRackTM streamlines the installation process by virtue of its simple fixed mounting bracket and articulating click-mount assembly. Once the mounting brackets are attached to the roof, Yes! Energy SeriesTM PV modules, designed exclusively for Yes! Mosaic™ systems are simply clicked into place. The unique mounting system and PV modules do not require traditional wiring assemblies; instead electrical connections are achieved through the modules themselves. Similarly, ClickRack’s™ self-grounding feature eliminates another traditional installation step and the materials needed to electrically ground modules. The net benefit of the ClickRack™ mounting system is a much faster, safer and more secure, low-profile installation. One of the more unique aspects of the ClickRack™ mounting system is how easy it makes disassembly. In the event of a remodel or re-roofing project, modules simply snap out of their brackets with unparalleled ease. Unlike other mounting systems, in the event of individual module replacement, any single module in an array can be removed without the need to remove any adjacent modules, dramatically reducing replacement time. The mounting system is also fire-code friendly, helping to streamline the permitting process. “The introduction of ClickRackTM with our Yes! Mosaic™ residential energy systems make it extremely easy for homeowners to match one of our systems to their requirements and rapidly begin to achieve energy independence. Our Yes! Solar Solutions franchisees are very excited about this new product and the competitive advantage it will provide them within their territories.” said Todd Lindstrom, President Yes! Solar, Inc. “With Congress passing the 8-year extension of the federal Investment Tax Credit and raising the limit of the tax credit from $2,000 per system to 30% of system cost, residential solar systems have never been more economically attractive. Homeowners seeking relief from rising electricity costs are the real winners and our Yes! Mosaic Energy Series™ systems are designed to allow them to quickly take advantage of the new ITC and the savings the systems will deliver.” Yes! Mosaic™ residential energy systems featuring the new ClickRack™ mounting system are exclusively available through Yes! Solar Solutions energy outlets and will be reaching Yes! energy outlets in the first quarter of 2009.
