Choosing the right solar panel for your home

Congratulations on your decision to switch to solar panels for your home! How do you pick the best solar panel for your home? That could be a difficult decision for many given that there many brands of varying quality of solar panels in the market. There are a lot of factors that you have to consider to before choosing the solar panel for your homes, after all they’re going to power your home, right? Factors like performance, durability and the longevity of your solar installation predominantly depend on the solar panels and the other solar components installed. The best way to assure that you get the maximum value out of your solar installation system is to make sure that your have the best components installed.

While people buying solar panels are increasing every single day, we should also be careful not to be fooled by brands that can lead us to losing money.

Iinergy’s Solar experts have helped us put together this quick guide so that you would be able to select the best solar panels for your home. While requirements of different homes will vary based on various conditions, the performance of your system will be determined by the cost of your solar power. With considerations on factors like your available budget, size of the solar installations space, best suited plan for you, we hope that this technical information would help you choose the best solar.

Dimensions of solar panels

A typical Australian household consumes about 20kWh of energy a day on average. Figuring out what size will your house need to produce the required amount of energy can be decided based on your power consumption. By referring to your previous energy bills, you can consult with our expert technicians on what panel would fit you’re the best. A 5kW solar system would meet most of the daytime during regular days.

Manufacturer of the solar panel

The solar panel market has a variety of manufacturers who produce panel of varying models and power outputs. The trick here is to purchase a Solar panel manufacturer who are distinguished in their offering and their quality. Solar panels are usually separated into 3 tiers based on their quality and performance;

Tier 1

Brands that manufacture solar panels with premium quality and expert manufacturing experience are usually Tier 1 manufacturers. Iinergy always provides your with solar panels from Tier 1 manufacturers.

Tier 2 & 3

Tier 2 & 3 companies are lower ranked manufacturers according to their quality and production. We at iinerg make sure you are getting the top-of-line solar panels from tier-one brands for the best performance, durability and power output.

Warranty Comparison

This is one of the important factors that most solar owners forget to look out for. The manufacturer’s warranty is an essential factor you have to consider while buying a solar panel. Usually solar panels come with 2 types of warranty; The first one is the performance warranty which is roughly around 25 years, while one cannot rely on this warranty, the second warranty, that is the manufacturer’s warranty, is something that you should always take into account. Comparing this to find out which is the best suited for you will help you decide your budget as well.

Solar Panel Performance Ratio

The Solar Panel Performance Ratio is defined as the ratio between the actual power performance of the solar panel to the manufacturer’s specification provided for the solar panel. This Ratio is another important factor we must consider when looking out to buy the solar panel. The panel performance ratio is tested after the manufacturer releases the product with specifications. Say, if the performance ratio is 90% for a 300kW specification, then the panels produce only ~270kW in the real world. Generally, you can expect anywhere between 90% to 94% ratio for a good solar panel.

Compare Efficiency

Solar Panel efficiency is the power to surface ratio of a given Solar panel. This means that smaller surface with higher output means that the efficiency is higher. This efficiency factor is generally, over 16% to 18% efficiency is good for solar panels. While more efficiency doesn’t mean more power output. It’s just to compare the efficiency in terms of power output to surface ratio or size or the panel.

Temperature Coefficient

Solar panels are surfaces that are always in the heat of the sun, quite literally. The temperature coefficient measures how much the power drops for every degree rise in temperature. It generally ranges from -0.4% per °C (good) to -0.5% per °C (not as good). While solar panels love sunlight, they do not prefer heat. Making sure that we buy a solar panel that performs well with heat is important to the power performance of your solar panel.

These are some of the important factors that one must consider when switching to solar power. While some of these factors may seem to hard to wrap your head around, we have experts that will do this for you and make sure that you get the best solar installation of all things.
