If I could rate IntegrateSun as a zero I would. My experience with this company was horrible. There appeared to be a company of contractors; my solar project manager changed during the first four weeks of the project. One month after I had paid a 30% deposit before IntegrateSun responded with show-stopper requirement from the electrical provider for a $1 Million liability policy which would have been cost prohibitive. I request to convert this into a backup generator contract but IntegrateSun incorrectly responded that the same requirements would apply. Two weeks later IntegrateSun responded with a bid that was $3K higher than the company we selected to install our 18kw backup generator. This was one of the worst experiences that I have had with a service provider.
