Northcliff High - Walking on Sunshine

Northcliff High in Randburg, Johannesburg, took the leap of faith back in September 2017, to install a 40KW Solar PV System, way ahead of the curve, of what is surely soon to be an avalanche of Solar PV installations in Schools. And although Municipal KVA Incorrect Billing continues to question the viability of the investment, the above graph, which details the electricity consumption during the last weekend (17th & 18th August 2019), clearly illustrates the enormous savings being made from the school's solar system.

The graph is the real-time monitoring representation of electricity consumption from 00:00 on the 17th August 2019 to 24:00 on the 18th August 2019.

NOTE: Between 08:00 to 16:30 during the 17th & 18th August (deep into the winter), Northcliff Electricity Consumption was practically ZERO, as a direct result of the Solar PV System. The equivalent amount of electricity is of course being generated each and every single day of the year and will continue to do so for the next 25-years.

Therefore, whilst the vast majority of schools are presently receiving electricity increases of 12,5% in Johannesburg, Northcliff High will continue to mitigate these increases for some time to come. Once the issue regarding the Municipal Billing Error has been resolved and the credits granted by the Municipality, we will report the overall savings made and the correct payback of the long-term Solar Investment.
