Characteristics of a Good Quality Solar Panel
You may go on word of mouth and shortlist a few solar panel brands, but the ultimate decision rests with you. There are many factors to take into consideration when you’re choosing a solar panel for your home. These include solar panel efficiency, solar panel manufacturer’s warranty, and of course, cost.
You’re probably installing a solar panel to cut down costs and save on finances, but to realize this goal, you’ll need to be careful in your selection. Here are a few characteristics of high quality solar panels that you should watch out for.
Normal or High Efficiency
Efficiency refers to the amount of energy that a solar panel can convert into electricity every square meter. You can choose between a normal efficiency or high efficiency solar panel according to your needs. A normal (15%) efficiency solar panel produces about 150 WP per square meter of electricity, while a high (20%) efficiency solar panel produces about 200 WP per square meter of electricity.
The difference between the two working on the same system is a high efficiency solar panel would take up less space than a normal efficiency one. However, both would produce the same amount of electricity as they are working with the same system.
Temperature Coefficient (Pmax)
Strong light performance is measured by the temperature coefficient (Pmax) or maximum power point. It refers to the percentage of power output drop for every degree increase in panel temperature over 25 degrees Celsius. Solar panels heat up fast, and solar panel temperature can increase to 75 degrees Celsius during high summer temperatures.
When you are choosing a solar panel, you should look for one with a low temperature coefficient. This will help limit losses, which will turn out beneficial for you in the long run.
Durability
The warranty that comes with the product should give you an idea of how confident (or not) the manufacturer is in the product. A short warranty period is a warning sign that the brand probably doesn’t expect the product to last you a long time to come.
Most brands offer a warranty of 25 years, so you should be able to compare and gauge. Obviously, no matter how good the solar panel, you will need to maintain it to expand its lifespan for it to serve as a good investment.
