Wind & Sun designed an off-grid PV system, supplied equipment and trained installers from the charity Solar Without Frontiers for a school in Mvimwa, Tanzania.

Wind and Sun were delighted to be chosen as the preferred supplier for the charity Solar Without Frontiers (SWF) recent off grid PV installation for a school in Mvimwa, Tanzania.

Wind and Sun advised SWF on system sizing and configuration as well as supplying key components and arranging transportation of goods including a new diesel generator to Tanzania. Wind and Sun also tailored a specific training course for the SWF installation team which was held at their training centre at Humber Marsh, Herefordshire ahead of the installation team’s trip to Tanzania.

The off grid system consists of 30 REC 250W PV panels mounted on a T Type array frame and connected to Sunny Mini Central 7000HV. This is then connected to a Sunny Island 5048 off grid inverter/charger to charge a battery bank. A back up diesel generator is also connected to the Sunny Island system.

This new off grid system means that the school can enhance it’s education offering through increased  IT system capacity. It will also result in a significant annual fuel saving in the region of £3,200 as well as the associated logistical costs in getting fuel to this remote location. It also insulates the schools finances against the vagaries of fuel price inflation.

"On Saturday 6th of October evening, the lights went on at the school without the background noise of the generator – to everyone's amazement."

Wind and Sun has also been involved with Solar Without Frontiers in sizing and supplying another system for a hospital in Malawi. This system which consists of a 7.5kWp PV array and a Sunny Back up has now been delivered and it is intended to be fitted in February 2013.
