PHOTO VOLTAIC (PV) POWER SYSTEMS
SOLAR PV (PHOTOVOLTAIC) SYSTEMS
Solar PV systems:
- use sunlight to generate electricity for your domestic use
- store excess electricity in batteries for later use, or
- feed into the electricity grid to reduce your electricity bill.
Factors to consider:
- your electricity demand—how much you use. The more electricity you demand, the larger the system and the greater the cost
- your budget—how much are you prepared to invest. Your budget may create limits on the size of the system
- your location—whether the mains electricity grid is available and, if so, how much would it cost to bring power out to your property and pay for ongoing maintenance of poles and cables on your property
- aspect—there needs to be sufficient space on your roof for the mounting of north-facing modules
- rebates—government rebates provide an incentive to householders to invest in solar. However these are subject to change from time to time.
