The cost of your solar installation, is quite relative to the size and brand, that you wish to install. Our aim is to advise and guide you, to a Solar solution that will pay for itself within a short space of time. A Battery back-up may add to the initial cost of the system, but it will certainly increase the ROI (Return on Investment). This add-on, will, give you peace of mind as it delivers power supply during power interruptions. When calculating feasibility based on cost, it is extremely important, to also consider the 15year performance guarantee on the Solar PV Panels

Solar Radiation is required for PV panels to generate power. On cloudy days, there is less solar radiation and the Solar PV panels will accordingly, produce less electricity. However, during rainy days, there is typically no solar radiation, and this results in no Solar PV power. Since the Solar PV generation will be poorer during these conditions, the system can alternately use battery and / or grid (Eskom) power to provide the shortfall of power supply, from Solar. If your system is connected to the Grid, Grid power can be used to re-charge the batteries during these conditions. You may also use generators, to recharge the batteries.

The batteries can either be used to supply power for a Hybrid / Bi-directional system, when the Solar PV is not supplying power at all, or just not supplying enough power. During loadshedding or a power outage, the batteries will provide power to all key components like alarm systems, entertainment equipment like WIFI, TV, COMPUTERS, etc. and essentials like Fridges / Freezers. A Grid Interactive solution will assist to reduce the risk at hand.

It is important to note – A Grid Tied system requires either Grid or Generator power, to supply Solar PV power. Grid Tied solutions can thus, be integrated to run with Generators.

Commercial Solar PV system are generally designed to reduce electricity costs and therefor reduce overheads, and simultaneously reducing carbon emissions. Grid Tied systems are typically implemented for businesses, as the cost per kWh installed is much lower. Subsequently the Return on Investment for Grid Tied systems are much shorter.

Residential Solar PV Systems normally includes a battery component to supply power to Safety, Security & Entertainment equipment during Loadshedding. The battery component as well as the Inverter function to manage the batteries increases the overall cost of such a system. Grid Tied systems can be implemented for Residential application to supply power demand during the day.

Solar PV systems is ideal for electricity savings and thus reducing monthly expenses, both for Residential and Commercial applications. The Return on Investment is influenced by several factors including the current electrical tariff and the design of the Solar PV System. Grid Tied systems offers the shortest Return on Investment due to the relative low cost as oppose to systems which includes batteries like Hybrid, Bi-Directional and Off-Grid Systems.
