Single phase inverter are the most common inverter used in residential and small commercial applications while three phase inverters are commonly used in large-scale commercial and industrial power systems. Read more on this topic.

A UPS is a load shedding solution and doesn’t contains PV panels. A hybrid system is the most common residential system, and both produces and stores power, saving you money on electricity and having backup power for load shedding or grid outages. A grid-tied system doesn’t contain batteries and only produces power, it is mostly used on large commercial sites. An Off-grid system fully meets all your energy requirements and isn’t connected to the municipal grid, they are very expensive and often unrealistic in a residential setting.

The unit kWp stands for kilowatt peak and tells you how high the output of power that PV panels produce is. The unit kWh stands for kilowatt hour and 1 kWh is equivalent to 1 ‘Unit of pre-paid electricity’, it is the battery’s energy capacity and the amount of energy put into the battery from the system and ‘units of electricity’ available to power your loads. The unit kVA stands for kilovolt-ampere and tells you how much power is being used in the system overall, it’s used to describe the size of the inverter.

Solar panels can withstand heavy rainfall and hail and are capable of operating in high and low temperatures. However, extreme cold may reduce their efficiency.

Tier 1 solar panels are made utilizing the highest quality materials and the highest quality of silicon. The solar panel will perform more effectively if the silicon quality is higher. Furthermore, Tier 1 manufacturers use advanced robotic methods to regulate the production process, reducing or eliminating human mistakes in the process. Lastly solar panels from Tier 1 manufacturers come with a 12-year product guarantee and a 25-year linear performance warranty.

The ideal angle for maximum solar panels will depend on the area’s latitude and other local factors. In Port Elizabeth the optimal angle is around 30°, however, for rooftop installations, we generally install it flat on the roof at the degree of the roof.

Yes, as long as they are securely mounted and installed at the ideal angle, solar panels can operate efficiently on a flat roof.

It typically takes one to three days to install solar panels, an inverter, and a battery in a household. The planning and material order can vary from 2-6 weeks, depending on stock availability.

From 1 March 2023 to 29 February 2024, those who install rooftop solar panels can receive a rebate of up to 25% of the panel cost, to a maximum of R15,000.

Several studies show that solar panels increase the value of the property by 3 to 4%, however, this is dependent on a number of factors and some systems can increase the value by as much as 8%.

The Genergy Solar batteries and inverters have a 10-year warranty, the mounting structure has a 20-year warranty, and the PV panels have a 25-year warranty.
