One of the very best investments I have made for our home. We have almost completely earned back what we invested only 3 years ago. The bonus is that I feel we are doing our part to protect our world. Als I needed to contact RGS regarding our system internet reporting and once again they were superior. They listened helped me to try to fix it myself and when that didn't work they set up an appointment right away. Within weeks everything is back on track without losing any solar power. This is the best solar company around.
