Grid tied systems consist of only 2 key components – solar panels and a dedicated grid tied inverter. All the electric power generated by the solar panels feeds through a mains synchronized inverter directly into your distribution board and offsets the power you would normally consume from Eskom. It will of course only do this when the sun shines! If the panels produce more power than what is being consumed at the time, the balance will flow back into the network and it will actually reverse the electricity meter (not all types of meters can do this though). Since no batteries are used, no independent energy can be stored for later use. This means that energy required at night will still be obtained from the network.

Below is an overview of what equipment is needed in a typical Grid-Tied Solar PV installation. • Solar PV Panels / PV Modules – The head end of a PV system that converts daylight into electrical current. As well as traditional Solar Panels, Solar PV panels can also be integrated into building materials where you may have traditionally used glass such as into canopies, skylights and balconies. • A Grid-Tie Inverter – Is used to convert DC power into AC power ready for use locally and for export to the grid.

Main benefits of Grid Tied Solar PV Systems:
• Energy provided by the Sun – Reduce your electricity bill and save money. • No expensive batteries required. • Sunlight is directly converted into electricity to use. • System payback is between 4 to 6 years. • Cost of energy yield fixed for at least 25 years. • No maintenance required. • Sell your own green power and earn money • Make mother Earth a better place to live.

Main disadvantages of Grid Tied Solar PV Systems:
• With no batteries, there is no independent energy storage.
• During load shedding or a power outage, no energy is available.
