Case study - S. wisconsin home - Grid Solar

Homeowner street view prior to solar install

What can solar from Watts Up Engineering do for you?

This Southern Wisconsin homeowner had a goal of zero net electric bill.  The site has direct Southern exposure and most landscaping is clear of the roof to prevent shading.

Challenging roof section with shade.

Before Solar - Challenges

 No site is perfect and this one was no different.  The westernmost (left in top picture) roof area had shading from a medium deciduous tree.  Shading analysis showed a potential for significant electric production gains with minor tree trimming, which the homeowner performed prior to installation.  Other site preparation included comprehensive main circuit panel reorganization.  Also, structural analysis showed the original truss designs lacked sufficient bracing, which we corrected prior to installation and permitting.

Solar panels installed and looking great!

After Solar - Satisfied Customer

This satisfied customer is enjoying the benefits of a net zero yearly electric bill.  The install is a 14 kW system with an annual production of over 22,000 kW-hrs.  Plus, we designed the system for a phase 2 future expansion of 6 kW to create a 20 kW system with an annual production of over 31,000 kW-hrs.  During the install, we had the opportunity to place the equipment for future electric vehicle charging (part of phase 2 plan).  This install required structural engineering, zoning, permitting, and utility interconnection services.
