I recently had Arch Electric install a rooftop solar system coupled with 4 Kilowatt labs supercapacitor modules and a 12kw Solark inverter. The super caps and inverter were new to Arch but their team of engineers and installers did a wonderful job to provide a very well-performing system. To those unfamiliar with Supercapacitors they act like a battery but can charge faster, weigh less, and can be cycled at least 1 million times( not a misprint). A truly revolutionary development in energy storage and the first installation of its kind in Wisconsin. I would highly recommend Arch Electric for any unique installation. The Arch team has the expertise and personal to perform this type of work in an ever-changing environment of rapid technological change.
