Andrew Koyaanisqatsi's company Solar Energy Solutions, Inc. did an excellent job installing my solar hot water system. It is a complex job with a lot of handwork and detail required from him and his workers. He is knowledgeable about all the types of solar energy installations and determined to be sure that clients get all the incentives and tax deductions to which they are entitled. He installed a new type of digital pump controller, which has worked without problem. He wanted to be sure that the plumbing was leak-free and tested everything in stages during the installation.
