Is a 500W solar module in sight?
LONGi Solar this week said that it has invented a new “seamless soldering” technique that could help it produce a more efficient solar module. As a reminder, the more solar cells you can pack into a module, the more efficient it is. And the more efficient your modules, the fewer you need to achieve the wattage you seek in an array. By using less modules, you reduce the overall installed cost of solar.
