About Integrated Building Systems
Integrated Building Systems (IBS) is a Milwaukee-based electrical contracting and solar installation company led by master electrician Darren Kalal since 2009. With more than 20 years of experience in the electrical trade, IBS provides traditional electrical contracting, solar panel installation, new construction wiring, service upgrades, and cogeneration system services for residential and commercial clients throughout the Milwaukee area.
The company’s electrical expertise is a core strength, allowing IBS to assess and upgrade the existing electrical infrastructure of older Milwaukee homes before installing solar panels. Many homes require panel upgrades, wiring updates, or other electrical work to support a solar installation, and IBS handles all of this in-house without the need for separate contractors. Solar services include site assessment, system design, permitting, installation, and monitoring setup.
Integrated Building Systems operates from 11414 W Park Place in Milwaukee and maintains a 4.8-star rating across 140 reviews on Birdeye, with consistently positive feedback on Yelp, BBB, and HomeAdvisor. The company’s service area covers Milwaukee and Waukesha counties, including communities such as Wauwatosa, Brown Deer, Menomonee Falls, and Brookfield.

Darren and his team at IBS were fantastic. As a master electrician, he understood exactly what our older home needed before the solar panels could go up. The panel upgrade and solar installation were done professionally and efficiently.
