8. avoiding more than 5 021 tons of carbon emissions per annum
How each solution will impact the environment
Saving tons of coal
&
avoiding more than tons of carbon emissions per annum
Fossil fuels emit climate-changing carbon emissions and are not a sustainable energy source.

9. Grid Interactive Solution
Solar Solution Types
Grid Tied Solution
Grid Interactive Solution
Off-Grid Solution

10. Grid parity is already a reality with battery storage!
Case Studies
Residential - Mossel Bay
Commercial - Roodepoort
Solution cost (per kWh):
Grid interactive R1,60
Grid Tied R0,64
Utility tariff (per kWh) is currently R1,71
Grid Tied (CWM) and Grid Interactive (Chamberlains) in Strubens Valley cluster
Grid capacity was very limited:
CWM – Grid Tied solution
Chamberlains – Grid Interactive solution
Scale solution with batteries under R1,00 per kWh (load matching is prerequisite)
Grid parity is already a reality with battery storage!

11. Solar carports means no strain on national grid
GridCars – EV Charging Stations
BMWI3 consumption
= 12,9kWh/100km
LCOE R1
R13/100km
1L/100km
Solar carports means no strain on national grid =

12. Conclusion Own generation is: Clean, responsible power
True Free Fuel Resource
Financially viable; and
A proven solution to overcome grid capacity limitations
Besides the clear opportunity to choose a sustainable energy source which can help preserve our delicate ecosystems, turning to solar has a great economic benefit too.
