How To Find Comparable Costs On Solar

Not all solar panels are designed equal. Solar installers select the equipment for their installations based on their technical specs and the needs of the job, and homeowners shopping for solar panel kits should do the same.

HahaSmart has developed a system that rates solar panels based on three fundamental principles: efficiency, performance, and warranties. You can utilize the same principles to correlate your solar equipment options. 

Efficiency

Solar panel efficiency is one of the most significant signs of a solar panel’s quality. It refers to how well a solar photovoltaic (PV) cell can transform sunlight into electricity and is presented as a percentage. Panel efficiency is particularly great if you have limited space to install a system and you want to maximize your electricity generation.

For solar panel performance, a higher percentage is better. The best solar panels currently sold on the market have an efficiency rating of approximately 22 percent.

Temperature Coefficient

A solar panel’s temperature coefficient class is a simple way to understand how well a solar panel will perform in less-than-ideal conditions. Like any other electronic device, solar panels operate best when they are kept reasonably cool (ideally around 25° C/77° F), and their performance can suffer if they overheat. The temperature coefficient can tell you how your panel’s production will decline during hot summer days. For every degree above 25° C (77° F), your solar panel’s electricity generation will fall by the temperature coefficient.

For instance, Grape Solar’s GS-S-160-Fab8 panel has a temperature coefficient of -0.5%/°C. This suggests that, if the temperature of your solar panel extends from 25° C (77° F) to 26° C (79° F), its electricity generation will decrease by -0.5%. If the temperature of your solar panel extends all the way to 35° C (95° F), its electricity production will decline by 5%.

As you incorporate solar panels for sale, remember that a lower temperature coefficient is greater. The best solar panels free on the market have a temperature coefficient of -0.25.

Warranties

All high-quality electronics producer will offer a warranty to show that they stand behind their goods, and solar panels are not separate. Aside from the technical aspects of the equipment in your solar panel kit, look for a strong materials warranty (sometimes referred to as a product or equipment warranty). The materials warranty guarantees against equipment failures occurring from manufacturing defects or environmental issues. Most manufacturers of solar panels for sale will offer at least a 10-year substances warranty. The best producers will provide materials with guarantees of 12, 15, or even 25 years.
