Okay, so you’ve decided to install solar panels in your home and produce electricity, but aren’t sure what goes into choosing solar panels. Hopefully, this list will guide you to make a good purchase. You should always keep in mind that a solar panel system is a long-term investment, hence there are many aspects besides the solar panels cost that you must take into account. Here’s a list of what to look for when choosing solar panels.
7 reasons to choose solar panels
1. Solar panel cost
This is probably the first factor that people consider when choosing solar panels. The cost of the solar panel is determined by different variables: the wattage, the physical size, the brand, the quality of the materials, and the durability (or warranty period).
A key guide on what to look for when buying solar panels 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 when considering the long term. Choosing solar panels can be risky, but they have a long lifespan of over 30 years, so ensuring a good quality system is more important than choosing the cheapest option.
2. Quality of solar panels
This takes into account how the panel is produced and the quality of the materials required to build the solar PV module. Different types of companies produce panels that differ in quality, efficiency, and price. Vertically integrated solar panel companies control every step of the production process. They put a strong eye on quality and invest heavily in research and development (R&D). When considering what to look out for when buying solar panels, quality must be one of your top priorities.
When choosing your solar panel supplier, it is wise to check the reviews or track records of the companies and see what experiences customers had with each one. Since you will be making a large investment, it is important to do some research and see if customers are satisfied with the product and customer service and if the company did everything it promised.
3. Energy Efficiency
Solar panel efficiency is how much light the panel receives is converted into electrical energy and how much power your system will generate. The more efficient the panel, the better. It’s 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 evaluate your requirements and find the panel that best suits your needs: this means don’t underestimate, but don’t overestimate your needs either.
4. Temperature coefficient
This refers to heat’s impact on a solar panel’s operating efficiency after installation. Because overheating solar panels shortens their life span, the lower the percentage per degree Celsius, the better. If you want to build a solar energy system, you should know what to consider when buying solar panels, and the temperature coefficient is one of them.
5. Durability and Warranty
This could be an indicator of the manufacturer’s reliability when selecting solar panels. Solar panels’ warranty typically lasts for 25 years. If the manufacturer does not offer a long warranty period, you might suspect that your product is not very good, and therefore you do not want to take any responsibility. In this case, be careful not to be fooled by a tempting price, as you might regret it in the long run.
This takes into account the physical size and the wattage, and is crucial to know before choosing solar panels. You need to make sure that you install a solar panel system that is large enough to power all of your appliances, and also that you have the space to install it. The physical size of the panel will vary depending on the power of the system (the more watts, the larger) and the type of solar cells used to build the panel.
The wattage of the solar panel is probably the most important thing you need to get it right, as underestimating the number will lead to a lack of power, and overestimating the wattage will only mean spending more money than you need.
7. Types of solar cells used
There are various kinds of solar panels with different efficiencies. Although their names may sound confusing, it’s good to know at least the name, so you’re not off-topic if your provider mentions it.
Monocrystalline silicon offers great efficiency and heat tolerance. Solar panels like the JA solar panels based on polycrystalline (or multicrystalline) silicon cells are now the most popular choice in residential installations. To get the latest JA solar panels price, contact us. Also, there are amorphous (or thin-film) silicon cells, which use the least amount of silicon and are not the most efficient. A crystalline panel will be smaller than an amorphous panel for equivalent power.
Choosing solar panels for your home
Now you have the tools for choosing solar panels that best suit your needs and immerse yourself in the world of solar energy. You should always compare different offers and see which provider you find most convincing. But, for now, you can contact our solar equipment one stop shop where we will answer all your questions.
