With more than 40 years of solar system installations under our belt, we can emphatically say YES. As long as you have a qualified solar installation contractor, use proven equipment and technology, and install the system correctly, it is guaranteed to work. We have installed solar systems that have been in operation for over 30 years running. The only reason a solar system wonu2019t work is improper installation and/or faulty equipment. We guarantee our work so if your system, for any reason, isnu2019t working the way it should, weu2019ll come and take care of it right away.
