A PV system uses solar panels to convert sunlight into electricity. The electricity produced by the panels is DC and is converted into AC by using an inverter to power electrical appliances and lighting, and the DC electricity can be stored in rechargeable batteries for later use.

When your panels are exposed to a lot of sunshine the production is from the panels is good. When the day is cloudy the production drops, this depends on how dark the clouds are. The rain can act as an advantage in that it can help to clean the panels, removing dust and bird dung. This therefore means that the panels will always produce even on a cloudy day, it’s a matter of how much production will be produced on that day based on the weather.

The most important consideration for maximum production in the Southern African region is to ensure that the panels will be as close to north facing as possible. This is not to say that other orientations are impossible, but the best yield is produced on north facing surfaces. You must also be sure that there are no trees or objects nearby that will result to shading. The state of your roof is important too, as we cannot install PV on asbestos roofing.

The cost of a PV system is determined by the size and the quality of the equipment that will be used to install the system. The size of the system is determined by the site’s electricity consumption.

A grid-tied system is a PV system that is connected to the national grid. A site uses or sells their solar electricity production, and purchases the shortfall from Eskom. An off-grid system is not connected to the grid. Such a system only uses electricity produced by the panels and stored in battery banks in a daily charge-discharge cycle.

If the system is off-grid, then no. However, if the system is grid-tied and your consumption is more than your PV production you will have to pay the electricity bill as you will still be using some of Eskom’s electricity. The difference will be in the amount you will pay after you have installed your PV, the bill will be less than before.

Each system is designed in a bespoke, site specific, so payback periods vary slightly. At Genergy, we strive to reach full capital recovery within 4 years.

Genergy only uses Tier 1, A-class panels, with a 20 year linear warranty and performance guarantee.

PV is a great way to save on electricity costs, but there are other steps that you can take before you install a PV system to ensure maximum savings. Consider replacing incandescent light bulbs with energy efficient LED or induction lights, replace electric stoves with gas stoves and electric geysers with gas, solar or heatpump alternatives.

A solar water heating system is made up of a solar geyser (tank) and collector (panel). The combination of these two main components (solar system) is designed to use solar energy to heat water thereby replacing traditional electric and gas geysers.
