TESTIMONIAL

Ed, Greencastle, IN says:

My sales rep Greg was as before the best! He not only was helpful in making sure that I had everything I needed, but he provided me with alternatives that have worked out great! I have had previous experiences with other Solar or alternative energy online stores that have never met the great service I have received from AltE. I have recommended your store to others and I am sure that they will consider AltE when they are ready to go with alternative energy.
