Solar panels are in vogue these days and investing in one is a challenging job, more because the decision you take now will determine how well you are able to derive benefits of these panels in the long run. So, your investment in solar panels is definitely not for a shorter time span but for several years to come. One important aspect that you have to keep in mind is that cost is not the only factor that will influence your decision, there are other factors too. However, since cost is also one of the many factors that will decide how much to invest; a little about it has been explained in brief below.
Cost of solar panels
The solar panel cost will be determined by the following factors that include-
- How big the solar panel is (in terms of physical size)
- How much Watts it is of
- Quality of the material with which it has been made
- Certifications, if any
- Number of modules
Another factor that will also determine the cost is whether you are buying the entire power installation system or just a module for your home. Ideally, the cost decreases if the number of modules is more in number.
Aside from the cost factor, the material with which the solar panels have been manufactured also count. Not only that the procedure that was involved in manufacturing these panels are also taken into account while considering solar panels for investing in. Whether or not the power installation system has valid certifications has to be looked into. This is because such power systems will be eligible for the rebates that are offered by the government. And if these norms are not adhered to, government rebates cannot be enjoyed. So, prior to investing in the solar power systems, don’t forget to take this matter into account.
Tier system to determine solar panel quality
There are 3 tiers as far as solar panel quality is concerned. The three have been briefly explained in the paragraph below. These are also included in factors that will help you to choose solar panels.
- Tier 1 – Characteristic features
These are the manufacturers of solar panels that are involved mainly in Research & Development. They take the onus of monitoring every step in the manufacturing process of solar panels. They constitute 2% of the manufacturers of solar panels. They have been operating in this field for more than 5 years now. They produce excellent quality solar panels.
- Tier 2 – Characteristic features
These manufacturers have been operating in the industry for the last 2 to 5 years. Although they do not invest as much in Research & Development, they make use of both robotics as well as manual work for production. These manufacturers of solar panels offer good quality solar panels that are affordable too.
- Tier 3 – Characteristic features
This tier comprises manufacturers that are solely into solar panel assembling. They are not engaged in any form of Research & Development efforts and they are not manufacturers of solar cells. The solar panels offered by them may not be a good choice as the quality may be compromised as the production work is carried out manually. So, output and results may vary from one technician to another.
