"Yellowlite did a great job. They were competitive against other solar installers, and then offered an end of the year discount that made them the winning bid. Gross cost was $2.53/W, and I will get 26% back as a tax credit. It took ~8 weeks from signing contract to install, and installation took 3 days for the electrician, 1 day for rooftop crew. They were very flexible and great to work with. For example, instead of routing conduit on the roof to connect two separate panel sections, I asked them to go through the attic, and they made the change without a second thought. The quality was great, and the electrician took his time to make the installation look good. The city inspector didn't spend much time looking at the system once he knew it was YellowLite--he was already familiar with their quality. Although the final 20% was earned for them upon startup, I did have to chase down permitting status with the utility, but only lost 1.5 weeks of solar (in cloudy February)."

"Sunivation was our hero! When our original solar panel company, Sun Power, went out of business we did not have anyone to service or repair our system. Tim and Sunivation came to the rescue. He was able to find our problem within minutes, install replacement parts, and had our system up and running in no time. Not to mention the original defective parts he replaced just about started a fire. He was professional, polite, and informative. From now on Tim and Sunivation will be my first call whenever I have an issue with my solar panels. Thanks for everything Tim!"

Four Seasons Heating, Air Conditioning, Plumbing, Sewer & Electric began as a father-son business operating out of a Chicago garage in 1971. They went from home to home repairing furnaces and air conditioners with the goal of offering their customers honest and competent service. No extra charge for 24 hour emergency service.\n\nTo this day, Four Seasons still isn't charging for emergencies, nights, weekends, or holidays. Our technicians are still providing the same kind of friendly, local service. Best of all, we are now available to serve neighborhoods all across Chicagoland with 600 trucks on the road.\n\nWhat started as two people with a shared belief — that homeowners deserve straight answers and fair pricing — has grown into one of the most trusted home services companies in the Chicago area. When something goes wrong with your home, you shouldn't have to worry about who you're letting through the door. With Four Seasons, you never do.\n

"The estimator was a really friendly guy and had a lot of information about the business that Kapital is in. Fortunately, although I had lots of questions, he was not pushy on services or needlessly verbose about them which I appreciate. He seemed to get what I was asking at every step.

We asked for an estimate for EVSE. We have a parking slab off the alley (so no garage w/ electric). We talked about lots of options for that. They seemed very comfortable with our situation which isn't entirely straight forward and I really appreciated that as I was afraid that many of the installers who do this work would want to walk away from any significant work.

We received an estimate for hooking into our panel and trenching a line through the back yard to the parking slab. We discussed using an existing basketball hoop mount as the mount point which the estimator was happy to consider (the stands for chargers are insanely expensive). We talked about solar on homes and parking canopies with solar as well.

Overall we are not ready to take the dive with this yet but I've come away with a decent understanding of the service, cost, and more. Kapital will be first on our list when it's time to move.

Thanks guys!
