Tesla Powerwall Installation in Horam

OHM Energy were asked to carry out an energy audit for a local village hall, that was in need of some modernization. The hall was heated with original storage heaters that had very limited control and were of an age for replacement. With the hall being used for various purposes including a children’s nursery, for parties, functions and as a designated crisis center for the local village a number of things need to be considered in selecting the best and most economical system.

With a perfect south facing, unshaded roof, Solar PV was a must, also considering the hall is utterly electrically dependent, it made complete sense.

Tied in with the Solar PV is a Tesla Powerwall, with a back-up gateway. Upon last checking the hall is 80% off grid, by combining the Solar PV and Tesla – we hope to take the hall completely 100% off grid during the summer months. With the hall being the designated crisis center it was also important that they remained with power in the event of a power cut. We have ensured that the hall has heating, lighting, refrigeration and hot water in a blackout situation.

The hot water cylinder was about 20 years old, with poor insulation, an inexpensive and worthwhile upgrade.
