Monocrystalline Solar Panel Aiko Solar Comet 620W AIKO-A620-MAH72MW-G2 ABC Mono-Glass (Silver Frame / MC4)

Aiko Solar Comet 620W: Efficiency N-Type ABC, Maximum Shadow Mitigation and Connectivity to 1500V

Searching an outstanding photovoltaic performance and a lower standard energy cost (LCee) finds its final response on the solar panel Aiko Solar Comet 620W. This module is unchecked with conventional technologies thanks to its cell architecture ABC (All Back Contact). By moving all electrical connections to the back of the wafer, the front surface is fully clean and exposed to solar radiation, eliminating losses per metallic shading and allowing to maximize the space of residential and industrial roofs. This avant-garde self-consumption component is perfect for working together with microinverters latest generation or connect to centralized high voltage systems.

Thermal immunity and optimization against partial shading

One of the biggest challenges on any solar plant is the impact of shadows projected by chimneys, trees or dirt. The serie COMET 1N of Aiko solvents this problem integrating technology Partial Shading Optimisation. This development allows that, before a shadow in a specific cell, the thermally isolate the affected area protecting it from hot spots (Hot-Spots), at the same time as the general production of the chain or String suffer from drastic performance falls.

Additionally, the panel offers an excellent coefficient of power temperature of -0.26% / ° C. This ensures that, during the summer months in which the solar plates reach high temperatures, the loss of efficiency is minimal compared to the standard market modules. If you are designing an isolated or hybrid system with this level of production, you can efficiently manage the surplus coupling a bank of lithium batteries great capacity.

Light structure Mono-Glass and original connectivity MC4

Unlike heavy double glass modules, the model Aiko-a620-mah72mw-g2 bet on a mono-glass configuration with a single tempered glass of 3.2 mm high-transmissive. This choice reduces the total weight of the panel to only 27 kg, facilitating transportation and decreasing structural loads on covers, without sacrificing an apex of mechanical rigidity thanks to its silver anodized aluminum profile. The connection is supported by terminals Original MC4 certificates to work on Strings of 1500V DC, suitable for plants that seek to cover large distances and optimize wiring costs (BOS). If you are looking for a compact solution for your home without the need for great works, this solar panel can be the ideal technical basis for configuring advanced balcony Kits.

Frequently Asked Questions section (FAQ)

1. What real difference provides ABC technology in front of a traditional perce panel? ABC technology places all electrical contacts at the back of the cell. By eliminating the metal buscloth bars from the front, there is no obstacle that makes shade to the silicon surface, which maximizes the uptake of light and raises the efficiency of the module to an impressive 24.0%.
2. How do you mitigate the Aiko Comet panel Losses for shading on the roof? This panel has an intelligent optimization system (Partial Shading Optimization). When a sheet or partial shadow covers an area, the panel prevents the performance drop from affecting the entire circuit, actively controlling the temperature to neutralize hot spots or hot-spots.
3. What advantages does a 3.2 mm mono-glass panel have in front of double glass modules? By having a single tempered 3.2 mm glass combined with a subsequent technical sheet, the panel reduces its weight at only 27 kg. This remarkably simplifies the installation on roofs with weight limitations, at the same time offering an excellent resistance against hail impacts up to 40 mm.
4. Why is the compatibility with 1500V and original MC4 connectors important? It allows to design series of longer within the same photovoltaic installation. When raising the working voltage at 1500V, the current strength is reduced by the cables, decreasing the electric losses due to voltage falls and saving costs in the copper wiring section (BOS).
5. What is the long-term guaranteed performance of the Comet 1N series? Aiko Solar says by contract a degradation of less than 1% during the first year of the module. As of the second year, power attenuation is limited to a low 0.35% per year, thus guaranteeing the panel at least 88.85% of its initial power after 30 years of continued operation.
