"I wanted to let you know I am very pleased with the service you gave & the quality & condition of the solar panels I received from EcoDirect. I will purchase more items in the future from EcoDirect and will be sure to tell others about your fine operation."

"I enjoyed ordering what I needed. It was simple and fast, no issues what so ever. If I need something else and its at a good price, I will defiantly order from here again. Also the shipping is at a good price."

My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.
