Identical Solar Panels but Different Efficiency

If you are planning to install solar panels in your home and calculating the size and number of panels that will be needed, be informed that the same size of solar panels may produce varying amounts of electricity. These discrepancies arise due to the variation in their functioning due to age and quality of different solar panels. Also the technology used in making solar cells affects their efficiency. For instance, the traditional solar panels are not as efficient as modern day solar panels. So, if you are buying solar panels from a trusted wholesale manufacturer, the quality will be guaranteed and you can be almost assured of utilization of the latest technology in the solar panels you buy.

Generally, solar panels have an average lifespan of 20-25 years. However, their value and wattage may decrease slightly over time. Let us consider a scenario where a solar panels wholesale dealer has two identical solar panels. One is sold while the other is left in the storage for four years. So, the solar panel that is left in the storage will be more valuable then the one that is being regularly used and has been actively converting sunlight into electricity.

The above reason explains why it is better to buy a new solar panel then going for a used solar panel. You might save on the initial cost but the overall efficiency of the solar power system will be slightly lower.

In a nutshell, although two solar panels may seem similar, there are number of factors that you must consider before buying them. You might find a given solar panel is expensive per square foot than other one, but that does not confirm that the second one is a better deal. Quality, age, making, storage and technology are some of the factors that play major role in cost of solar panels. Therefore, it is always advised to buy solar panels from a trusted solar panel wholesale or retail merchant with whom the quality is guaranteed.
