Solar Power uses Photovoltaics (solar panels) to convert solar radiation into electrical current. Systems operate with solar panels and an inverter to convert DC into AC power. The system can be coupled to a battery bank to ensure continuos electrical supply when sunlight is low.

Besides using the electricity generated in your home, you can earn additional money by selling the surpluss back to the utility.

Turnkey Energy solutions offer a full turn key service from design to installation:

  1. Off Grid System - or standalone. This type of system is used where the is no electricity grid or where a client wants to be completely off the grid. The size of the solar array, system components and battery reserve capacity is dictated by the properties electricity consumption and climatology and sun shine within the area.

  2. Gried tied systems - Interacts with the electricity grid. This system does not have a battery back up. It's only function is to generate electricity and feed back to the utility. It can slow stop or reverse your electricity meter and therby save you money. At the moment these systems are illegal in South Africa except for systems generating more than 1 megawatt of power. However, things are changing and Eskom and most municipalities will grant a feedback license if approached.

  3. Hybrid systems - by far the most poular in South Africa. This system has a battery and additional controls and will provide back up power when there is load shedding. Hybrids can consume the electricty produced and feed excess back into the power grid - depending on meter types. System sizing depends on the appliances or devices requiring power - either the whole property or just selected appliances such as lights and TV.

When it comes to a solar system, there are no standards or so called kits. Every system must be sized correctly according to the power needs. There are many complex calculations involved such as physical location f the site, wiring and connections.

In order to size a system correctly, we need to know and calculate the peak power consumption per day (KW) and the total KW/h you expect to use per day. i.e. we need the total KW you are using when all your major appliances are switched on at the same time. One should add about 20 % to cater for in rush current - when the fridge washing machine lawnmower and etc switch on.

To establish your power consumption we start by looking at 12 months of electrical bills, including differences between summer and winter. We must then estimate when different appliances are used as there are peaks and valleys during the day.

To save costs on the system:-

- Use gas for cooking
- Use solar water heating
- Install power saving lights

These items can run on solar but they are heavy duty electricity consumers:-

- Electric heaters
- Underfloor heating
- Geysers
- Washing machine and tumble driers
- Electric stoves
