At Diesel Electric Services we have installed our own Grid Tied PV System without battery back-up. This system is supplying power to our sales office.
The system comprises of 72 x 200 watt photovoltaic panels connected in series and parallel combination, this is wired into three grid-tiered inverters (GTI) which is feeding power directly onto our mains in the building.
This system has two significant advantages for us, the first is that we contribute our green initiative and secondly we benefit from a significant saving on our monthly utility bill. By taking cognizance of the rising global electricity demand, the scarcity of fossil fuels and as a consequence of that, their rising costs, we believe that this will be a beneficial investment for our company.
Residential PV, multiple commercial rooftop PV installations in the 15/17/36/50/200/ 2 x 300kWp range. DES is currently contracted to do all the AC and MV work and transformers on the 3MWp PV system with Rhino Energy for Telkom. DES is currently working with the PV technology and larger power ratings for UPS/ battery / diesel and gas plant, there is nothing with a 1MWp PV plant that worries us at all.
