A Guide to Choosing the Right Solar Panels

Solar power is a rapidly expanding industry in Australia. The world is shifting toward cleaner energy sources, and solar power is emerging as one of the leading contenders. 

Solar panels in Australia are not only less expensive than traditional energy sources like gas or coal, but they can also save money during their lifetime.

Using solar systems, Australia generated around 10% of total electricity in 2020-2021. And more than 30% of Australian residents have Rooftop solar PV systems. 

Solar panels are an appealing choice for power, whether you are worried about the environment or your cost. Solar panels can be put on a roof or the ground, with initial prices ranging from $3,000 to $30,000. However, you must consider a few factors when choosing a solar panel in Australia. 

  1. Solar Panels Warranty 

Most solar panels in Australia come with a 25-year performance guarantee and a 10 to 15-year product warranty from the manufacturer. Solar panels of higher grade come with a product guarantee of up to 25 years.

The performance warranty protects against panels that deteriorate prematurely. The product warranty covers system underperformance caused by malfunctioning modules. 

A service contract for an extended solar warranty costs between $350 and $500. The level of coverage is the same as the manufacturer’s warranty, but it is extended for an additional five to fifteen years.

  1. Solar Panel Specifications

Regarding efficiency, commercial solar panels in Australia (19.6 per cent) outperform residential solar panels (18.1 per cent).

A domestic solar panel system typically has 72 cells and is 65 inches by 39 inches, but a commercial solar panel system measures 78 inches by 39 inches and has 96 cells. 

Commercial systems might take up to a month to complete due to their size. However domestic solar panels typically take one or two days to install. Commercial solar panel systems are generally white, whereas residential ones are black or white.

  1. Solar Panels Cost

Solar panels have become significantly less expensive in Australia in recent years. Solar panels nowadays range in price from less than a hundred dollars to more than five hundred dollars. 

The cost of solar panels is determined by several factors such as their capacity, brand, physical size, material quality, and lifespan. If you’re purchasing a complete system, the price will also be determined by the number of panels included in the bundle. 

  1. Solar Panels Efficiency 

The following are the primary elements influencing solar panel efficiency:

Sun Intensity – The effectiveness of solar panels improves as the temperature drops and decreases when the temperature rises.

Solar shadowing – complete or partial shade by neighbouring trees or buildings can result in decreased production and electricity losses.

Cloud Coverage – An unclean environment reduces the effectiveness of solar panels by allowing less sunlight to fall on them.

Soiling – Solar panel soiling caused by dust, ice, snow, debris, or bird droppings can considerably reduce efficiency.

Solar panel maintenance is also critical to their optimal operation. Making frequent physical inspections and cleaning the panels regularly ensures direct sunlight. 

To summarise, solar panels are an essential component of any solar system. Professional solar installers can assist you in selecting the ideal panels for your needs. Professional installers are technically proficient and know how to install in the most efficient way possible to maximise output.
