What is a Soar Grid-Tie Inverter
Most solar systems installed today are connected to the national electricity grid. And for good reason. The electricity grid can be thought of as an enormous and very cheap battery. When your solar power system generates more than your home can use, the grid will take your excess electricity. When you need more electricity than your solar panels can generate, the grid will happily top you up with all the electricity you need.
Grid-connected solar systems need grid-tie inverters. These are special solar inverters that will synchronize with the electricity grid. They produce grid compatible 240V AC (sinewave) electricity from the DC voltage that your panels produce. The electricity from a grid-tie inverter is indistinguishable from the grid’s electricity. In fact, often it’s actually better quality power than the grids!
What is kilowatt peak (kWp)?
This refers to the output power achieved by a solar module under set standard test conditions. This standardized test for panels across all manufacturers ensures that the values listed are capable of comparison.
In South Africa, 1 kWp of solar paneling will generate approximately 1 710 kilowatt-hours per year.
What is a kilowatt hour (kWh)?
This is a measure of energy and is used to define the amount of energy used over a one-hour period. This is conventionally the unit of power referred to on your electricity bill.
