The warranty period differs according to the brand but, most of the panels have a warranty period of 25 years. The warranty often provides 5 to 10 years coverage for defects in the manufacture of the product.
Why Solar | Solar Panels & Inverters
Yes! The warranty period differs according to the brand but most solar panels have a warranty period of 25 years. The warranty often provides 5 to 10 years coverage for defects in the manufacture of the product.
Warranty cover varies from supplier to supplier. However there are minimum requirement for CEC approvals and rebate claims.
Your solar system will stay with your house, so it is important to look at how many people could be living there along with your current usage, if plans change over the next 15 to 20 years.
Electricity from the solar panels is converted into supply suitable for domestic appliances via an inverter. In a grid interactive system, a grid -interactive inverter is used to convert the DC(direct current) power generated by the solar panels into the 240AC (alternating current) power needed by the mains grid and by appliances in the home.
Most people in residential areas going solar, invest in grid connect systems as they could be paid a premium for every kilowatt of electricity their solar system feeds into the grid.
PV stands for "Photovoltaic" which means electricity obtained from light. Every time a photon (a piece of light) reaches a solar panel, the photon could be reflected , passed straight through or absorbed. When it is absorbed , the energy that the light particle carries is transferred to electrons in the solar cell, generating electricity.
Depending on the preferences (such as performance, cost effectiveness) any of the above described ones would do the job.
There are several types of solar PV panels available - monocrystalline, polycrystalline, multi crystalline and thin film (also known as amorphous), etc.
Originally, all panels were made from slices of silicon cut from a single large crystal. It is known as a monocrystalline panel. These are more efficient but more expensive than the other types.
The second type named as multi or polycrystalline is manufactured from silicon which has been cast in blocks. They are cheaper to produce and cheaper to buy and have been improving efficiency to that of monocrystalline panels.
The third type known as thin film panels(amorphous silicon) are less efficient than panels but at the same time have less production cost than the others as the silicon is spread in thin layers on a backing material or directly onto a glass plate.
The most recent breakthrough in solar panels has involved panels made of a combination of crystalline and thin film technologies. These are high efficiency panels with minimum output loss but at a premium price.
Roof -integrated solar panels are also available.
Even within any of the above technologies performance between brands will vary.
Extreme heat is a one factor in Australia which can significantly affect the energy output of the solar system. There are also other factors like shaded areas, trees, roof ventilators or antennas which prevent the fall of sunlight on the panels due to which the flow of electricity gets blocked and also panels should be kept dust and dirt free.
Solar electricity is being used to provide electricity for houses all over the world, covering a wide range of conditions.. Now-a-days solar panels are manufactured in such a way, that they can tolerate a wide range of climatic conditions, including snow, frost, hail and high temperatures. Solar panels are put to test for tough conditions during the time of manufacturing.
Factors such as angle and panels, orientation, temperature, etc will need to be verified. Solar panels can tolerate a range of climatic conditions. Ideally, a solar site in Australia or Southern Hemisphere should be of north-facing roof or ground space that is not shaded during the day. Panels can also be mounted on roof areas facing west/east, but output will be lower.
