would be the best solution in purchase price and maintenance costs, because no batteries are installed.
In many countries subsidised - but not in South Africa
Here you rather get punished with a Meter-Fee if you bring your for free generated Solar-Power to the Municipality Grid or it is even vorbidden by Eskom.
Housholds with an usage of up to 500KW/h a month could have 80 to 90% ELECTRICITY for free for the next 20years with an investment of only +/- R60.000. But the Meter-Fee with +/- R340 per month and the little amount you get paid what you generate to the grid makes it not profitable (calculated for 2015)
If you need power during the day and no needs for batteries - a good investment
Or in areas with no power supply - SOLAR POWER is still one of the best Alternatives
But get expensive if you want to store your generated power and have to invest in Batteries
To get benefits
You have not to invest R100.000 or more.
You can start small and extend step by step.
You can start with smaller units like a Geyser RETROFIT KIT
(what is incl. installation +/- R14.000)
You install a Geyser RETROFIT KID with 3 Solar Panels to a standard 150L geyser and the costs for this Retrofit Kid is amortized in plus/minus 4 years.
After this +/- 4 years your geyser runs to 80% for free
And this saving will be -with continues Eskom increases- more as today
And with some add. Electrical Installation your Pool Pump runs most time for free on this 3 Universal-Solar-Panels
