Best Solar Panel Installation in Honolulu HI

Received 3 quotes on establishing a washer & dryer in my garage & installation of 2 disposals that company supplied. Diamond Head $5,000, Company B $1,900, Company C $2,100.
They are extremely overpriced.

I visited homedepot to replace windows and doors worth over 20k. Every visit I had to wait over 30min for someone to help me. In fact, i called from inside the home Depot to get a sales person. Sales person said that I must pay for the installer to come over the house to measure. Paid $50 deposit and the installer showed up an hour late. No calls for over 2 weeks. Called home Depot for estimate. Received an estimate with inaccurate window counts. Called home Depot to resubmit. No estimate uptodate. Called Home Depot, sales person said that the installer quit. They have to send another installer to come and measure again. No one ever contacted for one month. Called home Depot again and the person said sorry I asked for my deposit back and went elsewhere.
