During the first weekend of April, 2025, the Friends Theological College solar electrical system was brought back to life after being down for a period of two years. It was resuscitated by a Nairobi company known as Themes Electrical and Solar Services. The twenty four solar batteries that were replaced had a life span of eight years. The newly installed battery units have ten blocks of lithium ion batteries. Each one has a lifespan of fifteen years, with a five years warrantly. The advantage of these lithium ion batteries is that they have a life of 6000 charging cycles as compared to the old ones, which had only 3000 charging cycles.
Stephen Warui, the chief engineer behind this installation, pointed out that lithium ion is the latest technology in the battery industry. He emphasized that this technology is eco–friendly and that it requires minimal maintenance—just dusting the system and making sure it stays clean. Additionally, Steve said, “Lithium ion batteries do not require large space to install. Most of them are stackable and easy to install.” What is more exciting is that they are also user friendly. The client is able to interact with the system by taking the readings from the display of the batteries.
With the resuscitation of the solar batteries, FTC's electricity bills from Kenya Power will hopefully go down, since the electricity is being supplemented with the solar panels.The administration block, which is the heart of the institution, is on 100% solar usage, thereby ensuring that the running of the administration is secure, even when there is an electrical outage.
Heartfelt appreciation to friends of FUM who supported the battery replacement and technical support to promote the use of green energy at FTC.
