Successful Project

Mr. Parker 400w portable solar panel project in Oklahoma, US.

Parker runs a small textile factory in Oklahoma. And although he’s been using renewable energy for a while. He has built-in stand panels, making it hard to adjust them according to the sun’s direction. 

He reached out to us. His MAIN challenge was positioning portable solar panels in the sun’s direction. So, we recommended him to our flagship 400w portable solar panels.

Parker ordered 28 units, which were delivered in 12 days. He called to appreciate us and says he now enjoys maximum energy output on his panels.

Leeline Energy is one of the best solar companies I’ve worked with this year. Their customer service team was very friendly. And their panels…Top Quality! It has been 1 year since I bought my 400w panel, and so far so good.

Evelyn L Hollis

Leeline Energy just added a long-life partner. I can’t think of a better solar company than these guys. They are always available to answer my solar panel inquiries. My 400w portable panel arrived last week. And I’m sold out. I’ll definitely order more panels before this year ends
