Thanks everyone. This is the route I am going to go

Good afternoon.
I have a lady who has worked for us for many years. We are moving to a retirement centre and she has decided to go "back home" to the Eastern Cape. In the village she is in, there is a community borehole with a 5000L tank on a small stand and a solar borehole water pump. And that is it.
She wants electric lights and possibly a TV. Please advise what would be needed solar wise (panel; battery; inverter, and MPPT) for the following.
12 LED 7 watt 220V globes of which only 7 would be on for an average of 6 hours per day.
A LED TV of 100watts 220V that would be uses on average 3 hours per night, but possibly another 3 hours during the day.. No other electrical appliances expect cell phone charging
I want an inverter as 7W LED 220volt globes are cheap and available everywhere, whereas 12V LED globes are expensive and difficult to come by.. If the use of the TV requires the use of a massive battery please do two specs, 1 with and 1 without a TV. I want an overkill on the solar panel, they are cheap, and I want to compensate for cloudy days.
thanks

Thanks. So I start again. Solar is not about saving money, but about having electricity 24/7/365. At my age I don't think I would ever get the return on my investment, BUT I will, I think, get my money back when I sell, and from what I've seen in the complex, be on top of the list when prospective buyers come to look at properties. The 24/7/365 electricity supply still remains the priority way above everything else.

I have a similar problem but been doing some investigation and noting of events.  I live in a retirement complex.
What I have installed:
I have solar hot water heater. I have a gas stove and oven. Sunicom M5000h-48 48VDC Inverter  4.8KWH 48volt Deichmann Lithium-ion battery YLR48100. 6 * 550 watt solar panels on the roof facing north I live in Pretoria All globes are LED and total wattage is 95watt. I have two fridges - both inverter - and 1 deep freeze, rated A+ TV, Computers and other small non element items. Backup grid electricity for the geyser is not wired thru the inverter. What I have noticed.
When ever I turn on my electric kettle - 1600watt - the inverter switches  to use grid electricity.  This even happens mid day, cloud less sky an temp of 31C
About two weeks ago we had a power outage at the retirement village.  It started at 10H00 the Friday morning and power was restored at 15H30 on the Saturday afternoon. 29h30min of no power.  I only was aware of the power outage on Friday night when I went to check that all doors locked etc. and saw no street lights were on.  During the time of the power outage I used the TV extensively, probably 10 hours, boiled the kettle 5 times but used the gas stove to boil water after I realized that there was no grid power; used the micro wave 900watt for probably 15 minutes in total. My fridges were also on, Internet modem etc.  During the daylight hours there was full sun and the temperature in the high twenties and low thirties. Both my wife and I had a hot shower on Friday night, which can only have been hot water from the solar hot water system.
With the power outage, due to the prevailing circumstances, it has proved to me that the inverter and battery can handle my electricity needs without grid power backup.  
I can only think that there are settings in the inverter and/or battery that have been set incorrectly.  I would like these settings to be that Grid power is only used whjen the battery level reaches a certain level of discharge, whatever is recommended.  Having said all of that the installer of the hot water and solar power was a qualified electrician. 
Any advice would be welcome. 

Thanks very much for this.     I have downloaded the manual and extremely informative and got me spending a lot of time looking at YouTube and exploring the WWW.  I will have to get someone in to change the panels into 3 strings of 2 panels each.  
I am considering enhancing my solar hot water system of evacuated tubes with solar electricity and increasing the panels at the same time I change the string of panels.  Is there a topic on this on this forum, and if so how do I look for it?
 
Thanks again
 

@RookieRod The max PV input is 4400 Watt. That is 8 of your 550W panels . 10 Panels 5500W is exceeding your limit by 25%. So 8x550 W Panels max.
The inverter only has 1 mppt so you cannot use different orientation roofs spaces.
I will change the Geyser element to 2kW or even lower if avialble. Then heat the geyser when excess power is avialable. a Timer on the geyser supply can be be added to assist you. I find the cost of these heating systems expensive.
As you are a pensioner and only 2 adults this should work well for you.

Guys, thankyou so much for all this info.  I have changed some settings and boiled the kettle twice this afternoon - plenty of sunshine - and did not use the grid. I also reset menu items 12 to 46v and 13 to 54v.  Just that made the world of difference.  I have read up a lot and watched YouTube as well.  I am fully aware that both Google and YouTube are not the holy grail but I am now aware of what can be done.  What is blatantly obvious is that I do need a monitoring system.  I have a list of things I want to ask and query but that is for another time.  I unfortunately do not have access to the electricity meter, but will ask the groundsman of the complex if I can be given a meter reading each day until I get a monitoring system.  I am pretty certain that the equipment was purchased from "The Sunpays" but will investigate.  Can anyone recommend/suggest what monitoring system I should go for?  At about 17H30 this afternoon the battery was at 52 point something volts, so I am smiling like a cat at the cream.
Again a big thankyou to all.
