Solar Panels are now available from hundreds of different manufacturers using different technologies like crystalline Silicion, CIGs and Cd-Te. The solar panel’s efficiency also varies a lot, depending on the solar panel manufacturer and the technology used. The cost of the solar panel can also vary a lot depending on the retailer, size of the solar panel, technology and the brand. This makes buying solar panels a confusing problem, though most residential and commercial buyers are not involved leaving the decision to the solar installer\/EPC company. SunPower<\/strong> is a US company which makes the most efficient solar panels using its monocrystalline solar cell<\/a> technology which gives efficiency of more than 24%. The company sells black solar panels with efficiency of 19-22%. The company is a solar system integrator and developer, as well as a builder of some of the largest solar farms in the US. The company benefits from the leadership of the French Oil Giant Total<\/strong>. SunPower operates in all the main segments of the market and has reputation for selling some of the highest quality solar panels in the country.<\/p>\n

SunPower Solar Panels<\/h1>\n

SunPower sells the highest efficiency solar panels made from its record breaking\u00a0monocrystalline solar cells\u00a0which have more than 24% efficiency. SunPower solar panels deliver high efficiency solar technology, utilizing\u00a0SunPower Maxeon patented technology with back-contact\u00a0solar cells. The company will design solar panels to serve all the global markets at large. The higher efficiency panels will serve markets like USA and Japan, whereas the panels with efficiency ranging between 19-20% will serve the other markets.<\/p>\n

SunPower Residential Solar Panels<\/strong><\/h3>\n

X Series<\/strong><\/p>\n

SunPower X-Series solar panels deliver 44% more power per panel and are more than 21% efficient. Ideal for partially shady and hot rooftop temperatures conditions. It utilizes 96 monocrystalline Maxeon cell technology, built on a copper base and is aesthetically pleasing.\"spwr\"<\/a><\/p>\n

      SunPower Solar Technology<\/strong><\/h3>\n

      Solar cells efficiency can vary from 18% to 24% for the normal monocrystalline silicon technology. Note solar cell manufacturers are constantly improving efficiency in order to lower their costs and get ahead in this competitive solar industry. SunPower makes the highest efficiency crystalline solar cells on a commercial scale.<\/p>\n

      SunPower Solar Panel Prices<\/strong><\/h3>\n

      SunPower solar panel prices are priced at a premium to the normal crystalline solar panels because the efficiency of the solar cells made by SunPower are higher. Also it uses monocrystalline solar technology which costs more to produce. SunPower generates almost 20-30% higher power per unit area, which makes it ideal for space constrained solar installations. For residential applications which needs good aesthetics as well, the black solar panels made by SunPower are a good fit. Solar panels these days are available at around 45 cents\/watt (wholesale price) or 55 cents\/watt (retail price). Since SunPower solar panels are more efficient and technologically more advanced you can buy it for around 65-70 cents\/watt.<\/p>\n
