Whether you go completely off-grid or simply supplement your household energy; solar power is a great way of coping with the ongoing increase in energy costs and loadshedding woes currently haunting the South African public. The initial investment of solar power is often enough to scare one off from going solar, but the truth is that the payback period of your investment and the subsequent rewards make solar power affordable to most home and business owners.
Solar Power systems are quite complex and are designed according to a number of factors which fall under four main configurations, namely:-
Off-Grid Systems
Off-Grid systems are independent of the utility power grid. They generate electricity, store it, and make it available for use without any connection to the power grid.
Grid-tied Systems
Grid-Tied systems use PV panels to generate DC power. The DC power goes to a grid interactive (grid-tied) inverter which converts the PV panel DC power to 240 volt AC power that is compatible with the power grid. The power from the PV panels goes (via the grid tie inverter) to supply the household power needs. If the PV system is generating more power than the house can use, the excess is sent out over the grid to supply others. If the house needs more power than the PV system can supply, then the extra is drawn from the grid as usual. Grid tied systems only work when the grid is up. If the grid power goes out, the grid tie inverter is required to shut down immediately.
