Description Longi 450W LR4-72HPH 450/MR is a monocrystalline 450W solar panel is ideal for self-consumption and industrial solar installations. Modules of high quality and resistance, made of polycrystalline silicon with an anodized aluminum frame. The Longi 450W LR4-72HPH 450/MR solar panels can be combined with state-of-the-art lithium batteries, as well as traditional lead-acid and GEL/AGM batteries with their corresponding charge regulator. At SmartSwitch Solar we offer solar panels recognized worldwide as prestigious in all its components, so much in its solar inverters, solar panels, regulators of load and batteries for solar installations. High-efficiency PERC technology, we can get up to 20.56% thanks to PERC technology (Passivated Emitter Rear Contact) TR technology with half cell aims to reduce the cell gap, increasing the module efficiency. Excellent response in conditions of low solar radiation, the design of the glass and surface of the solar cell ensure an excellent response in conditions of low temperature. PERC Mono: Optimize the performance of your installation. The PERC technology has meant a great development within the photovoltaic sector thanks to the increase in performance of the photovoltaic modules. This type of cells have a back layer that helps capture more solar radiation and a sheet that makes the excess sunlight rebound inside the cell and allows you to recover the surplus that the solar panels do not use. With this, we increase the capture efficiency of solar cells compared to photovoltaic solar panels with the same distribution, reducing the production price and the final cost of solar panels.
