What some of our clients have to say

Absolute joy to work with the staff at this company!!! As a solar installer I have been dealing with Greensun as my wholesale partner for more than a year know, and have experienced nothing buy joy on all levels of business: product quality, price, stock levels, turn-round time for items not already in stock, product knowledge, product training and after-sales support. I have and will continue to recommend them to anyone.

“Our electricity usage has been drastically reduced. Which is really pleasing, although the initial out lay is a dear one, ultimately, we will be better off. The best of all is that we will still have electricity at night when there is “load shedding”. Wonderful! I believe the personal touch and professionalism will make this company grow.”

Thanks again, I am super chuffed with the installation. You guys really do a very neat job.

“Just wanted to say thanks again for the solar system you have installed at my house. After nine months it is still running great!”
