What is a feed in tariff?
This is the amount of money your energy retailer (AGL, Red, Origin etc) pays you per kWh (unit energy) of electricity you send back to the grid. The amount varies according to your region, your energy retailer and the plan you have. The rate can be anywhere from 0 to 18c per kWh but is typically around 10c. Your solar system will first supply electricity to your home, any excess power will be fed on to the grid and you will receive a credit on your electricity bill for each unit "sold" to the grid. (If you have a battery, excess power will be used to fill the battery with surplus once the battery is full being fed on to the grid).
How long will my Solar System last?
There are 4 main components to a solar system; the inverter that turns the DC power generated by the panels into AC power for your home and the grid, the electric cabling that brings the power from the panels down to the inverter and then on to the meterboard, the panels that convert sunlight into electricity and finally the mounting system that affixes the panels to the roof.
Most inverters come with a 10 year warranty (some are higher), the cabling comes with our 10 year workmanship warranty, the panels have 25 year performance warranties and structural warranties ranging from 10 - 25 years (most are 15 or 25 years these days) and the racking companies warranty their products for 10 years. Having said this; solar systems are simple electronically and are made to a high standard, you can expect a solar system to last 25+ years with occasional maintenance.
