This is a very important Question, keeping it brief -

This is totally dependent on your needs and priorities and of course budget,

Firstly reduce your highest consuming electrical appliances, namely
- Geyser consumption at 40% convert this to alternative water heating, gas or heat pump or solar geyser, you will save 30-35% of your bill.
- Cooking on electricity, try to convert to gas cooking.
- Convert your lights to LED's.
- Run your swimming pool for a lesser total time period.

This reduces your bill immediately, but also reduces your 'load', this is what is used in calculating the size of your system.
The smaller the load the smaller the system you would require.

There are many very cheap products available, PLEASE ensure that you are getting proper materials and a proper installation team. The cheap route is the nasty route.

Install a medium sized solar array with battery backup that can be built on in time.

Alternatively, look to install a proper Lithium Battery backup System with a Proper Solar ready Inverter this is a foundation system that allows relief from load-shedding but is ready to accept panels when you are ready.

Or Purely for load-shedding you can look at one of our smaller inverter systems for essentials only.

PLEASE be aware of salesmen/women that promise you the world with a cheap quotation-this seems to be the trend the last few years, proper quality, lasting and safe solar installations are not cheap.
We look at your individual home's consumption holistically, taking into account all of your appliances and consumption by measuring this or your daily khw or unit usage,

Firstly suggesting alternative ways to reduce this consumption, with a little solar housekeeping,(a phrase coined by one of my clients),

The number of panels required to power your system and charge the batteries, is then calculated, suggest the best suited inverter to cope with this production and consumption and suggest suitably sized battery banks for evening usage,

We then meet to discuss how best to optimize the proposal,
Please see Article under Articles, short and sweet, there are many ways to design a system that suits your home, from different suppliers many differing opinions will come,

We like to work with you as an individual, as your home, your consumption and your consumption habits will be completely different to your neighbor.

Taking your specific requirements into account when designing and proposing a system, not a one system works for all scenario.

The equipment we use is of the highest quality with the relevant guarantees and of course our backup and after sales service.

Please be wary of the installers whom merely just want to give you a quote without proper investigation,
We like to work closely with our clients, discovering what they require and suiting that to their budgets, so at times we may install a smaller budgetary system, but on all the systems we install you can build up as your budget allows,

We can install a skeleton system or Battery Backup System that can just receive more battery backup and more panels without having to change the inverter down the line. 
The Solar Water Heating system tubes are made from tempered glass, and have been designed to withstand the terminal velocity of a hailstone, in 10years we have had two incidents of hail damage, 2 tubes cracked and three tubes cracked out of a 24tube system, simultaneously the hail storm damaged roof tiles and the clients vehicles.
All need be done is replace the damaged tubes with a new glass tube at a fraction cost
The photovoltaic panels are of the same quality, also put through ongoing serious testing,

No, the controller is designed to start pumping hot water through the manifold when the external temperature reaches 7degrees C.
The guarantees differ from product to product, but they are not only guarantees from ourselves, our suppliers and product manufacturer also uphold these guarantees to ensure you have a worry free experience,
Just contact us,
This also serves as to why we purchase the premium brands and deal with reputable suppliers.
We strive to install and supply the best quality materials available, to ensure lasting customer experience.

We do not cut corners or provide inferior items, we like to sleep at night, knowing you the client has a product that has earned its reputation with us, unfortunately this does come at a slight premium, but it is really worth every cent.

Our suppliers whom we have partnered with over the years, haven't been chosen randomly, we choose them because of the quality product they supply.
