Sunpower (SPWR)\u00a0<\/strong>is a\u00a0US\u00a0<\/strong>based solar system integrator and developer,\u00a0<\/em>building some of the largest solar farms in the US.\"Solar<\/a> The company makes the most efficient solar panels using its\u00a0monocrystalline solar cell\u00a0technology.\u00a0SunPower solar modules deliver 21.5%\u00a0efficiency, which is very high and means that the customers get more electricity and lower electricity bills.\u00a0The company was bought by the French Oil Giant Total. 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

JA Solar (JASO)\u00a0<\/strong>sells solar panels as an OEM Solar Panel Producer which means that it sells its solar panels to companies who put their own\u00a0brand names on solar panels produced by JA Solar.The company produces solar modules at low costs and supplies them to solar manufacturers globally.\u00a0The company has two\u00a0 solar cell\u00a0manufacturing\u00a0facilities, one located in Ningjin, Hebei Province, and the other in Yangzhou, Jiangsu Province.<\/p>\n

Distinguishing Features between JA Solar and Sunpower Solar Modules<\/h1>\n

JA Solar<\/strong>\u00a0modules come in both\u00a0monocrystalline<\/strong> and multicrystalline<\/strong><\/em>\u00a0<\/strong>make.\u00a0JA Solar makes i) SECIUM JAM5 72, ii) SECIUM JAM6 60, iii) SECIUM JAM6 72, iv) JAM(L) 72, v) JAM6 60 under monocrystalline panels and i) MAPLE JAP6 60, ii) MAPLE JAP6 72, iii) JAP6 72 and iv) JAP6\u00a0 60 under multicrystalline solar panel category.<\/p>\n

SunPower<\/strong>\u00a0Solar panels are used for\u00a0residential<\/em>\u00a0purposes primarily. They are classified into: i)\u00a0SunPower X Series<\/em>\u00a0\u2013 X21-335 and X21-345, ii)\u00a0SunPower E Series<\/em>\u00a0\u2013 SPR 327, iii)\u00a0SunPower Signature Black Solar Panels<\/em>\u00a0and iv)\u00a0SunPower AC Solar Panels<\/em>\u00a0\u2013 E 19\/240.\u00a0All SunPower Solar panels come in a\u00a0monocrystalline\u00a0<\/strong><\/em>make.
\n<\/strong>
\nCell Arrangement<\/strong><\/p>\n

SunPower Solar panels come in a monocrystalline make with 72 and 96 cell arrangements.\u00a0For JA Solar\u00a0they are\u00a0\u00a0125\u00d7125 mm, 126\u00d7126 mm and 156\u00d7156 mm.<\/p>\n

The available wattage for SunPower Solar modules are 240 W, 320 W, 327 W, 335 W and 345 W. For JA Solar modules the wattage range is\u00a0195 W \u2013 320 W.<\/p>\n

Frame<\/strong><\/p>\n

JA Solar panels have the traditional Aluminium frames, whereas anodized aluminium alloy frame is used for Sunpower modules.<\/p>\n

Weight<\/strong><\/p>\n

SunPower modules weight range is between\u00a017 kg to 18 kg.\u00a0JA Solar modules weigh 15kg, 15.5 kg and 18.5 kg.<\/p>\n

Load Resistance<\/strong><\/p>\n

The solar panels of both the companies can withstand wind speed and snow load\u00a0upto 5400 pa.<\/p>\n

Warranty<\/strong><\/p>\n

SunPower solar modules come with 25 years limited power and product warranty.\u00a0JA Solar come with a 10-year quality guarantee and 10-25 years power output guarantee.<\/p>\n

Standards & Certification<\/strong><\/p>\n

SunPower ACPV module are listed to UL 1741.\u00a0JA Solar Modules have IEC, CE and UL certifications.<\/p>\n

JA Solar<\/strong> has been the second best Chinese solar stock in 2013 giving a return of ~71%, as compared to the 30-40% return given by the other major stocks like Trina Solar and Renesola. The company performed very well in Q1 2013 with margins going up by 10%.\u00a0The company shipped 442 MW of solar products in Q1 2013.<\/p>\n

SunPower<\/strong> on the other hand has negligible presence in the Chinese solar market<\/a>. The company\u00a0is very strong in the USA.\u00a0SunPower panels have greater efficiency but the price gap is still quite large, when compared to the Chinese Solar Panels.\u00a0The Chinese solar panel makers provide decent quality solar panels at 50-55c\/watt, while\u00a0SunPower makes solar panels at almost 90c-$1\/watt.<\/p>\n","protected":false},"excerpt":{"rendered":"
