Suntech STP 445 S-H48-Nkh+ - solar panel 445 W
Description Suntech STP 445 S-H48-Nkh+
Solar panel Suntech STP 445 S-H48-Nkh+
96 n-type TOPCon half-cells
The module is based on 96 n-type TOPCon half-cells. Cutting the plate in half is already an established technique: less current per cell means lower resistive losses inside the panel and slightly higher resistance to partial shading, when the shadow from an antenna or chimney falls on only part of the module. And n-type silicon, unlike p-type, does not have the characteristic "drawdown" of power for PERC panels in the first weeks of operation due to the boron effect - the module reaches operating parameters immediately and maintains them stably for years.
How the panel behaves outside the lab
Glass-film construction and estimated life
STP 445 S-H48-Nkh+ is made according to the classic and proven glass-film scheme: tempered glass on the front and a polymer backsheet on the back. This is a lighter design than double-glazed analogues, easier to install and fasten, while tempered glass and high-quality cell encapsulation provide resistance to increased snow and wind loads, typical of certified Tier-1 panels. The operating temperature range from -40 to +70°C allows the module to be operated both in frosty winter and in summer heat without loss of resource. The maximum operating voltage of the system is 1500 V — a standard that allows you to design long string connections and save on cables and controllers.
Black frame without excessive shine
What you should know before buying
This is a monofacial module — generation comes only from the front surface, without the bonus of reflected light, as in double-sided panels. However, installers appreciate such modules for the predictability of the calculation: there is no need to take into account the albedo of the roof or the height of the installation, the system performance is easily predicted by standard calculators even at the design stage. For a typical sloping roof of a private house, where the panel lies close to the roof in any case, the difference with the double-sided analogue is mostly insignificant — and the price per watt is lower.
Who will it suit?
Suntech STP 445 S-H48-Nkh+ is a practical choice for a rooftop solar station for a private home or small commercial facility, where high efficiency per square meter, moderate panel weight, and a neat black appearance are important. If you need a specific system configuration for your roof and consumption, calculate the option with our managers: the model is in stock and can be delivered in a short time.
