Gunkul Engineering, a renewable energy developer and constructor, and Origin Property -- both SET-listed companies -- are forming a joint venture to install rooftop solar panels and directly sell electricity at inexpensive rates to households in residential areas. The new business aims to provide clean energy to homeowners as well as raise awareness about global warming, caused by high levels of carbon dioxide released by the burning of fossil fuels. Gunkul and Origin Property agreed to set up Origin Gunkul Energy Co with registered capital of 1 million baht to provide solar power service and develop charging outlets for electric vehicles (EVs).
