I used CodeGen a couple of years ago to install and maintain my Solar system. They did a good job analyzing my power needs and then recommending a configuration to me. I do use a battery backup as well which has been great so far in handling power outages and the occasional brown outs. The after sales service has also been good when I have needed it. The house is in Colombo and perhaps this helps with their overall responsiveness. I have been satisfied with the system and support services provided by CodeGen thus far and look forward to maintaining my relationship with them for any future Solar needs.

Hands-down THE BEST SOLAR COMPANY. A few months ago I reached out to CodeGen for a solar solution. They were the one company we selected out of the 4 companies that we shortlisted. My first point of contact was Mr. Indunil Palihawadana who addressed all our queries. Furthermore my brother had very specific technical specifications that needed to be met. Also CodeGen uses ONLY JINKO Panels to ensure consistency in product quality for all their clients. Indunil's team accommodated them all. They maintained transparency throughout the whole negotiating process. The team who came to do the installation was led by Mr. Chamara Withanarachchi who was an absolute specialist taskmaster who tirelessly planned out the panel installation. Chamara & his team worked around the clock to fix all panels and followed strict safety standards throughout the entire installation. Chamara's team even cleaned up after themselves at the end of the installation. I would always recommend CodeGen Sustainable Solutions as the choice company for any type of solar installation; may it be residential or commercial. Thank you CodeGen Team
