Frequently Asked Questions

To determine the number of batteries you need for your solar power system, you will need to calculate the amount of energy your household consumes daily, as well as the amount of energy your solar panels generate. Once you have this information, you can then determine the capacity of the battery bank you need. This is typically measured in kilowatt-hours (kWh). To calculate the size of the battery bank you need, you can use the following formula:

Battery bank capacity (kWh) = Daily energy consumption (kWh) x Number of backup days

With our help, you can be confident that your solar power system will be optimized for maximum efficiency and cost-effectiveness. Contact us now to get started.

To make up a 5kW solar system, you need ±12 solar panels, assuming you use 415W panels – that will actually give you 4.98kW. Each panel will be about 1.8 metres x 1.1 metre, so you'll need at least 23.7m² of roof space.

To convert your current system to solar completely can be very expensive and depending on your specific situation, will not always be cost effective. The storing of energy for the hours when the sun is not shining is the main challenge. A modular approach starting with solar water heating and a small inverter/ battery system to overcome load shedding is a much more reasonable approach.

Can I use the power grid as a storing device to feed electricity back into the grid during times when my solar system generates more than my consumption?

It is technically possible with the older types of electricity meters that work with an internal wheel, that can be reversed, but it is not legal everywhere in South-Africa to do so.

To answer the question one needs to understand the different systems on the market. There are two different approaches in utilizing solar energy to heat water:

Photothermal heating where the heat of the sun is used to heat the water and this can be done directly or indirectly, where another liquid that serves as a heat conveyor is used.
Through the use of Photovoltaic cells, commonly known as solar panels, to generate electricity that heats an element as is used in a conventional geyser.

It is well known that thermal heating is more efficient in terms of utilizing sunlight per square meter. This method has however certain practical drawbacks in terms of:

Weight of system on roof.
More parts that require maintenance in terms of pumps, pipes, valves etc.
Heat losses through conveying of water.
Limited lifetime expectancy.
Cost disadvantage.

To evaluate between different PV systems on the market, it is important to compare the wattage output and water volume capacity, as well as quality of components. It is also important to note that it requires more than 1500watt to heat 150 litre water to 55º Centigrade in the 6 hour efficient sunlight per day.

Yes, hail can damage solar panels if it is large enough. Solar panels are built to withstand golf ball size particles travelling at 100 km/h. It is also important to ensure panels are included in the building insurance policies.
