The solar panels are made up of photovoltaic (PV) cells, which convert radiation from the sun into direct current (DC) electricity throughout the day.

Although PV panels and solar panels are most efficient in direct sun, indirect sun also produces power energy. In the case of solar panels, partially cloudy or blocked sunlight can also generate energy.

The monetary value will depend on your energy goals and household consumption. It is also important to analyse your consumption and change or upgrade to energy efficient appliances where necessary. Please read our energy efficiency tab. Interestingly, the financial investment which most people perceived as a disadvantage is in fact a major advantage. In terms of solar geysers, all customers immediately start saving money.
The benefits of solar outperform the costs by far. You will be independent from Eskom, your alarm system will work even during load shedding or a power outage, etc etc.
Each and every customer is treated individually and a site inspection will determine your needs and requirements after which we shall forward a quotation and proposal.

The following factors influence the cost of solar for your home or business namely:

  • Your available, un-shaded, type of roof-space and inclination will determine the cost. A north-facing roof will enhance the energy produced on your roof significantly. The material your roof is built with determines the cost of the solar energy installation. Clay roofs are more labour intensive whilst flat roofs require an extra roof stand for optimum angle and optimum solar energy.
  • The current energy usage in your home or business will determine the size of your PV system and/or solar geyser and subsequently the cost of the system.You need to consider energy efficiency before calculating the costs of a PV system. It can be reduced drastically if you at least install a solar water geyser and replace your shower head. There is a lot more you can do. Please read our energy efficiency tab.

It depends on the inverter you use. When we use a “smart” inverter (4 ports), it is a all-in one inverter. You do not need another inverter or inverter charger, regulator, etc to charge your batteries and to control your back up system. This is called a hybrid PV system. You can then start with a UPS system followed by a grid-tied PV system and increase or expand your system as your goals and budget increase.

A smart inverter is a hybrid inverter, meaning that you can run your PV, Grid, Batteries and Generator all from one inverter. You therefore do not need an extra inverter when you want increase or expand your system.

A UPS (Uninterrupted Power Supply) is a battery bank and can be charged through the grid or PV modules. We normally select specific appliances to run for at least 2 hours during a power outage for a UPS system.A PV system is when you add modules on your roof to run your household with solar radiation. It is therefore a daily energy supply when the sun is shining. You can add a back-up system which you can charge with the sun instead of Eskom.

Using Solar and other forms of renewable energy reduces reliance on fossil fuels for energy production, thus directly reducing CO2 emissions. CO2 emissions contribute to global warming and severe weather, which we can start feeling at the moment. The average household can reduce CO2 emissions by as much as 20% by installing a Solar Geyser.

Batteries are made of cells and the thickness of a cell inside a car battery is thinner than a solar battery. A car battery’s lifespan is normally 2 years, whilst a solar battery can have a lifespan on up to 8 years.
