You may have decided to install solar panels on your home and produce your own clean electricity, but don’t know what makes a good solar panel. We’ve listed the characteristics of a good solar panel for you. We hope that this list will help you to make a better purchase. You should always keep in mind that a solar panel system is a long-term investment, hence there are many aspects besides the price that you must take into account.
How to choose a good solar panel
1. Cost of the solar panel
This is probably the first of the characteristics of a good solar panel that people consider when comparing them. The cost of the solar panel is determined by different variables: the size (in Watts), the physical size, the brand, the quality of the materials, and the durability.
An important factor for how to choose a solar panel is to consider the cost. However, it should not be the only factor to consider, as the least expensive panel might not be the most efficient and probably not the best option if you consider the long term.
Choosing solar panels can be risky, but they have a long lifespan (over 30 years), so ensuring a good quality system is more important than choosing the cheapest option. So, it’s better to pay for good solar panel brands like Canadian Solar Panels than to pay for repair costs later on.
2. Quality of solar panels
This is definitely one of the top characteristics of a good solar panel, which takes into account how the panel is manufactured and the quality of the materials used to build the solar panel. Different types of manufacturers produce panels that differ in quality, price, and efficiency.
There are vertically integrated solar panel manufacturers that control every stage of the production process. They give extra attention to quality and invest in research and development. Other manufacturers only assemble panels, but normally do not manufacture their cells and do not invest in R&D. They use more humans than robotic production, but produce the most affordable panels.
When selecting a solar panel supplier, it is important to read the reviews or track the background of the companies and see what experiences customers had with them. Because you will be investing a large amount of money, it is crucial to do enough research and see if customers like the customer service and product and if the company fulfilled its promises.
This is one of the crucial characteristics of a good solar panel, and takes into account the physical size and the wattage. You need to ascertain that you install a PV system that is big enough to run all of your appliances, and also that you have the room to install it. The physical size of the panel will depend on the power of the system and the type of PV cells used to manufacture the panel.
An average home would normally require a 4kW solar system. Watts are related to the production of the panel and are directly related to the cost of the system.
The wattage of the solar panel is probably the most important one among the characteristics of a good solar panel, as underestimating the number will lead to a lack of power, and overestimating the wattage will lead to spending more money than you need.
4. Energy Efficiency
Solar panel efficiency is one of the features of a good solar panel and means how much light the panel receives is converted to electrical energy, and therefore how much power your system will generate. It is not always the best option to get the largest and most efficient solar panel, as you could end up spending more money than you should for your energy needs.
You need to assess your requirements and find the panel that best suits your needs: this means not underestimating, but also not overestimating your needs. Similarly, you don’t need a Ferrari to drive your kids to school (you can, of course, but you can do the same for much less).
This could be an indicator of good solar panels and a sign of the manufacturer’s confidence in their products. Solar panels generally have a 25-year warranty (as long as the company operates).
If the manufacturer does not offer a long warranty period, you might suspect that their product is not very good and therefore do not want to take any responsibility. In this instance, be careful not to be tricked by a low price, because you might regret it in the long run.
Of course, it is important to properly maintain your solar panels to increase their useful life. Fortunately, they are easy to care for and do not require much maintenance.
6. Temperature coefficient
This refers to the impact that heat has on the operating efficiency of a solar panel after installation. Because overheating accelerates the aging of solar panels, the lower the percentage per degree Celsius, the better. That’s what makes this one of the characteristics of a good solar panel.
7. Types of solar cells used
There are various kinds of solar panels with various efficiency rates. Although their names can sound confusing, it is good to know the names, so you are not caught off guard if your provider uses them.
Monocrystalline silicon provides high efficiency and great heat tolerance with minimal environmental damage. Solar panels based on polycrystalline (or multicrystalline) silicon cells are now the most popular choice in residential installations. There are also thin-film silicon cells, which use the least amount of silicon. For equivalent power, a crystalline panel will be smaller than an amorphous panel.
8. Find good solar panels for your home
Now that you are aware of the characteristics of a good solar panel, you have the tools to choose the solar panel system that best suits your needs and immerse yourself in the world of solar energy. And finally, if you’re looking for good solar panel companies, you can get JA solar panels for sale right in Dubai.
