Case Study

Haad Tien installation

The Problem:

Haad Tien does not have mains electricity so all power is provided by diesel generators.  These generators are noisy, dirty and break down a lot. It’s inaccessibility by road means that taking large generators to be fixed is problematic and expensive. The end result is electricity that is not 24/7 due to cost and also intermittent due to the reliability of the generators. For a group of the long term residents there they wanted a more reliable service.

The Solution:

One of our consultants, Ottmar ‘Woodstock’ Rohrig, came up with a shared solar solution to provide electricity for 3 homes.  A total of 8x 250Watt panels giving 2000W of solar power  using brand new to Thailand non toxic, jungle proof, salt water based batteries that are not environmentally hazardous, have a life span of about 15 years and a capacity degradation of about 5% in that time.  These batteries provide a much cheaper solution over the same time period that traditional lead acid batteries.
