How to choose the right solar panels

How to choose the right solar panels

Adding a solar powered system in Australia not only yields financial benefits by helping homeowners and businesses save on their electricity bills but the environmental impact of adding solar panels to your roof is just as compelling. The traditional sources of electricity supplied by the grid in Australia are usually derived from non-renewable sources such as coal, nuclear and natural gas. By installing solar panels on the roof of your home, it becomes possible to contribute to a cleaner and more sustainable future while also saving big and getting a great return on investment.

A key guide on how to choose the right solar panels for your home is to consider the cost of the solar panel. However, it shouldn’t be the one and only factor to be considered, since the least expensive panel might not be the most efficient and probably not the best option if you consider the long term. How to choose solar panels can be risky but, they have a long lifespan (more than 30 years), so it is more important to ensure a good quality system than choosing the cheapest option.

Installing solar panels on the roof of your homes or business has never been as convenient and affordable as it is today due to advancements made in the solar industry. Solar panels perform a very unique function of harnessing the abundant power produced by the sun and converting this solar energy into usable power. There are plenty of advantages of adding a solar power system to your home or business. Since Solar panels allow you to make your own electricity, that’s energy that you don’t have to purchase from the grid and enjoy the freedom that comes along with it during peak hour charges, power outages, etc. Electricity prices are continuing to rise as the traditional sources of power are more expensive to produce, and considering the onslaught of longer and hotter summers predicted as our climate continues to warm, it is a smart investment to switch to solar power as it is the best way to lock in decades of predictable energy costs and is very reliable.

When choosing your solar panel supplier it is wise to check the companies’ reviews or history and see what experiences clients had with each of them. Since you will make a big investment, it is important to do a bit of research and see if clients are satisfied with the product and the customer service, and if the company did all that it has promised.

You should assess your requirements and find the solar panel that best suits your needs: this means not to underestimate, but also not to overestimate your needs.

Another factor to consider when choosing a solar panel is to consider the Temperature Coefficient of the solar panel. This refers to the impact that heat has on a solar panel’s operational efficiency after installation. Since solar panel overheating accelerates their ageing, the lower the percentage per degree Celsius, the better.

Another important factor to consider is the durability of the solar panel. This could be an indicator of the manufacturer’s confidence in its products. Usually, solar panels have a 25 year warranty (as long as the company operates). If the manufacturer does not offer a long warranty period, you could suspect that their product is not very good and hence they don’t want to take any responsibility. In this case, be careful not to be misled by a tempting price since you might regret it in the long term.

Of course, it is important to properly maintain your solar panels to increase the lifespan of them. Fortunately, they are easy to take care of and don't require much maintenance.

When choosing a solar panel for your home, it is also important to take into account the physical size and the size in Watts of the solar panel. You should make sure to install a solar panel system that is big enough to power all your appliances, and also that you have the space required to install it. The physical size of the panel will vary depending on how powerful the system is (the more Watts, the bigger) and the type of solar cells used to build the panel.

An average household in Australia would typically require a 6.6kW solar system. Watts are related to the output of the panel (a 390 Watt panel will generate 390 Watt/hours each hour under ideal conditions while a 100 Watt panel will generate 100 Watt hours) and they are directly related to the price of the system.

The wattage of the solar panel is probably the most important thing you need to get right since underestimating the number will lead to a lack of energy, and overestimating the wattage will lead to spending more money than you actually need.
