A solar photovoltaic (PV) system is a reliable and pollution-free producer of electricity for your home or office.
A PV system can reduce or completely eliminate the need to purchase electricity from your local utility.
A solar PV system increases the value of your home.
The system is maintenance-free. No hassle, no moving parts, and no worries.
You instantly begin saving money and reducing your family's carbon footprint.

Solar PV systems are designated by the amount of electricity they produce during "peak sun" times. For example a 3 kW system produces 3 kilowatthours of electricity each hour between 10:00am and 2:00pm on a sunny day. An estimate of the average amount of electricity produced each month is calculated by multiplying the size of the system by 130. So a 3 kW system would produce about 390 kWh each month. This amount will vary based on tilt and orientation of the panels. Also, the solar panels are very sensitive to shade.

Solar PV systems are completely scalable -- they can be as big or a small as you would like, limited only by your budget and your available roof space (if you're considering a roof mounted system). You can even start small and add-on later. The systems typically cost $6.00 to $8.00 per watt. So a 3 kW system would cost around $18,000 to $24,000, depending on the complexity of the installation before incentives and rebates are taken into account.

(Diagram from Mr Solar.)

A solar electric PV system consists of:

Solar panels collect molecules of sunshine, which are little packets of energy, and convert them into DC electric current.
DC to AC Inverter converts the direct current (DC) generated by a solar panel into alternating current (AC), that can be used to power appliances in your home.
Once the current generated by your solar panels has been converted from DC to AC, it can then be used to power your lights and appliances (AC Loads).
Your home solar power system can actually cause your electric meter to spin backwards through a process called net metering. When your system produces more electricity than you are consuming, it feeds the excess electricity into the main power grid and you earn credit on your electric bill.
Once electricity generated by your residential solar power system is directed onto the power grid, it can then be used by someone else and adds to the overall total of kilowatt hours produced by a clean and renewable energy source (in this case, the Sun!) The power grid will also supply you with electricity during those times you are consuming more than your system is producing.
