There are many solar panels available on the market. Many promises different results, from lower prices to better aesthetics. What factors should you consider when choosing a solar provider? These are the three main factors: efficiency, durability, and warranty.
Efficiency
SunPower(r), solar panels have been widely recognized as the most efficient available*. SunPower solar panels have no metal gridlines on the top, unlike other traditional solar cells. Each solar cell has ample space to reflect more light than visible rays, such as ultraviolet or infrared.
SunPower also uses interdigitated back-contact technology. This means all the wires carrying the electricity from each solar panel’s cells are attached to the back. This prevents shading and allows SunPower solar panels to generate more energy even in poor weather. SunPower’s technology is more efficient than traditional solar panels due to its strategic design.
Durability
SunPower solar panels are efficient and designed with durability in mind. SunPower solar panels have a copper backing that resists corrosion and weathering. This is crucial because solar panels are placed on roofs and can be exposed to extreme weather and temperature changes. All solar panels will eventually become less efficient due to exposure to the elements. However, the rate at which solar panels are degrading can vary greatly from one provider to another. For a conventional solar panel, this reduction of power output happens at an average rate of 0.5% per year. A SunPower solar panel degrades slower at 0.25 percent. This significant difference illustrates how durable SunPower solar panel panels are.
Warranty
All warranties are not created equal. Homeowners should consider more than the years that a solar system is covered to determine the true value of a warranty. Some warranties only cover the material but not the loss or interruption of power production. You may also find parts from different manufacturers. This leaves you with many warranties to choose from. SunPower provides the best comprehensive warranty in the industry. It covers both product and power. SunPower stands behind the whole solar system and not just the panels. SunPower is the only company that can fix any problem in the unlikely event of something going wrong.
SunPower isn’t satisfied with the product. SunPower guarantees that your panels will not lose more than 8 percent of their original DC output over the next 25 years. This is a clear winner compared to traditional solar providers, who only guarantee 19%.
Do your research and find the best option for you. SunPower is likely to be your first choice.
