In recent times, the cost of solar panels has reduced by a significant percentage. Today the pricing of solar panels depends on many factors. While selecting the solar panels, you need to learn more about factors to consider. Don’t make your buying decision based on price alone. Here, you will get the steps you need to consider to get the best solar panel that will offer better service,
The Type of the Solar Panel
There are two main types of solar panels: monocrystalline and polycrystalline solar panels. The panel that you will choose affects your system’s performance. It affects the price, power amount produced and the space needed by the system. Polycrystalline solar panels have a blue tint to the cells. These panels are less efficient than monocrystalline solar panels. You will have to mount more solar panels to produce more power. Polycrystalline panels are cheap compared to their counterparts.

Monocrystalline solar panels have a darker tin in the cells. They are more efficient than their counterparts and produce more energy. You will only need a few of them to create the power to serve you well. However, these solar panels are very expensive compared to their counterparts.
The Panel Colors
Choose solar panels based on the back sheet and frame color. Solar panels have many silicon cells on the back sheet. The back sheet surfaces via the gaps of the cell to create a design type. Other manufacturers make back sheets instead of the whole white solar panel.
Solar metal frames are either black or silver. The black frame panels have more aesthetic appeal but are very expensive. On the other hand, the performance of the black and silver frame panels is identical.
Solar Panel Sizes
Solar panels come in two main sizes: the 60 cells and the 72-cells. The two numbers represent the cells that are on the panel. The 72 cell solar panels are longer than the 60 cell panels. The large panel best fits vast areas like commercial roofs and ground mount systems. The 60-cell panel is best for smaller spaces like homestead roofs. The 72 cell panels are economical because they produce more power than the 60 cell panels.
The Panel Production: Output Rating and Efficiency
The panel’s output rating and efficiency affect the amount of power produced. Output rating is the three-digit number seen on the solar panel name.
The number represents the sum of electricity watts generated by the panel. Mostly panels range between 250 and 400 watts, but very few are above the 400 mark. Higher wattage means a higher price of the panel.
Panel efficiency is also very vital in the selection process. The efficiency is the percentage of electricity produced from the sun’s energy.
Warranty
It is important to check the warranty of the solar panel quality from the manufacturers. Many high-quality panels have a warranty of between 25 to 30 years. They even continue working after the expiry of the warranty period. Buy a solar panel that stands the test of time. The more the lifespan of a panel, the more money you save.
There are two warranties from the manufacturers: performance and product warranty.
Performance warranty assures solar panels can produce a specific amount of power. The generated power is regardless of their degradation.
Production warranty protects the solar panels from material issues and workmanship.
The Overall Quality
To buy quality panels, check the panel guarantee, customer reviews, manufacturer reputation. You also need to check the technical specifications. Technical specifications include panel efficiency, temperature co-efficiency, and power tolerance.
Conclusion
The solar panel selection process is overwhelming. You have to combine the output rating, panel size, and efficiency, among others to make the right decision.
