“Ra” is the ancient Egyptian Sun God. To the Egyptians, the sun represented light, warmth, and growth. This made the sun deity very important, as the sun was seen as the ruler of all that he created. All forms of life were believed to have been created by Ra! At Ra Source, we believe in the power of the sun – it just needs to be harnessed, and re-created.

We had Ra-source install Solar Panels at our factory one year ago and have been using Solar Power for our factory ever since. After using Solar Power, we have been able to reduce our diesel consumption by over 70%, thus achieving substantial cost savings while at the same time doing our bit for the environment by using clean energy. The generation of solar power has so far been as per the specified design and the cost savings have exceeded our expectations. Ra-source were very professional in arriving at our requirements, sticking to the project schedule, and executing a tidy installation. Their service has been very good after installation. We hope to see Ra-source spread their clean energy solution to more industries in the future.
