Reliable +1 The tenacity of the "lifeline" of SEAFOREST’s flexible solar panel. A global green carbon reduction transformation represented by photovoltaic energy is accelerating. As the core component of a photovoltaic power station, whether solar panel can operate stably, reliably and efficiently in the long term will directly affect the yield, maintenance cost and service life of the photovoltaic power station. However, in recent years, with the rapid development and involutionary competition of the industry, many companies have chosen to compress product costs to the extreme in order to win the market in terms of price, but this has also hidden various hidden dangers and risks in the products. To keep the "lifeline" of photovoltaic power stations, we first need to control the quality of the solar panel. For flexible solar panel, in their 25-year life cycle, they will inevitably experience the impact and test of harsh weather environments such as exposure to the sun, strong winds, heavy rains, hail, and heavy snow on the roof. The lightweight flexible solar panel innovatively developed by SEAFOREST use fiber-reinforced composite materials independently developed and new super-weather-resistant polymer composite packaging materials. And by superimposing the cell array and three layers of adhesive film with "transparent front film, glass fiber reinforced material, reinforced back panel" to create a 7-layer structure, it is not only more rigid and resistant to hidden cracks, but also comprehensively improves the high UV blocking ability and high weather resistance of solar panel, ensuring that there is no whitening, bubbling or stratification in the long-term test of high temperature in summer and severe cold in winter, and it can still achieve efficient photoelectric conversion without any leakage, providing 25 years of long-term guarantee. 信頼性+1 SEAFORESTのフレキシブル太陽光発電モジュールの「生命線」の粘り強さ   太陽光発電に代表される世界的なグリーン炭素削減への変革が加速しております。その中で太陽光発電所の中核部品である太陽光発電モジュールが長期にわたって安定的、確実かつ効率的に動作できるかどうかは、太陽光発電所の収量、メンテナンスコスト、耐用年数に直接影響します。しかし、近年、業界の急速な発展と競争の激化により、多くの企業が価格で市場を勝ち取るために製品コストを極限まで圧縮することを選択しましたが、これにより、製品にさまざまな隠れた危険やリスクも発生しました。 太陽光発電所の「生命線」を守るためには、まず部品の品質を確保する必要があります。フレキシブルパネルは、25 年の寿命サイクル中に、太陽光への露出、強風、大雨、雹、屋根への大雪などの厳しい気象条件の影響とテストを必然的に経験しなければなりません。 SEAFORESTが革新的に開発した軽量フレキシブルパネルには、独自に開発した繊維強化複合材料と新しい超耐候性ポリマー複合包装材料が使用されています。「透明フロントフィルム、ガラス繊維強化素材、強化バックシート」にセルアレイ及び三層ゴム膜を重ねて7層構造を構築することにより、より剛性が高く、隠れた亀裂に対する耐性が強いだけでなく、太陽光発電モジュールの紫外線耐性を全面的に向上させます。バリア能力と高い耐候性により、夏の高温や冬の厳しい寒さの長期テストでも白化、気泡、剥離が発生せず、効率的な光電変換を実現し、25年間の長期保護を提供します。...

SEAFOREST's flexible solar panels are suitable for installation on various roofs Solar power generation for factories and buildings, purchase price to be tripled, period to be shortened Economy November 9, 2024 17:30 [Members-only article] The Ministry of Economy, Trade and Industry will triple the amount per kilowatt-hour of power generation and shorten the period to about one-quarter of the current amount for the subsidy system for solar power generation operators. It will be implemented in fiscal 2026 as well. This will allow investment recovery in solar panels and other equipment to be completed in a short period of time, leading to the expansion of the introduction of renewable energy. The system is called the Feed-in Tariff (FIT) system, and solar power generation operators can purchase electricity at a fixed rate per kilowatt-hour if they generate electricity on the roofs of factories and buildings... 工場･ビルの太陽光発電、買い取り価格3倍に 期間は短縮 経済 2024年11月9日 17:30 [会員限定記事] 経済産業省は太陽光発電の事業者向けの給付制度について、発電量1キロワット時あたりの金額を現状の3倍程度に増やし、給付期間を4分の1程度に短くする。2026年度にも実施する。太陽光パネルなどの投資回収を短期間で終えられるようにして、再生可能エネルギーの導入拡大につなげる。 固定価格買い取り制度（FIT）と呼び、太陽光発電の事業者は工場やビルの屋根で一定規模以上の発電量があれば、1キロワット時あたり...

  23.5%! NTOPCon battery mass production efficiency hits a new high!   The conversion efficiency of NTOPCon high-efficiency double-sided solar cells in mass production reached 23.5%, which once again refreshed the N-type cell mass production efficiency, laying a solid foundation for the further popularization of N-type photovoltaic products.   The efficiency breakthrough is based on the N-type 158 square silicon wafer, double-sided power generation design, by optimizing the boron expansion process and redesigning the matching metallization process to increase the mass production efficiency to 23.5%, and the highest single-chip efficiency 23.8%. Compared with the 23.2% at the end of last year, the efficiency has increased by 0.3%, and the effective output has increased by 35%. Under the condition of no cost increase, the effect of improving efficiency and reducing costs is significant.

TOPCon mass production shows great potential Commercialized solar cells aim to achieve over 24% efficiency in the near future. Since PERC cell gradually approaches its efficiency limit, TOPCon solar cell is regarded as the most promising technology to be the major product in the next solar cell generation which can replace PERC cells. As technology of solar cell tends to be mature, the reduction of the cost of Si, glass, installation system and mounting rack is very difficult. In the future, the reduction of LCOE of solar energy depends on the increments of solar cells’ efficiency. Based on the current cost, 1% efficiency increment will reduce 2.82cents/Wp. Compare with PERC cell, TOPCon cell has higher potential on efficiency and stablility. LID and LeTID are always a big problem of PERC cells. However, the TOPCon cell doesn’t have the risk of LID and LeTID due to the features of N-type c-Si. Furthermore, the efficiency limit of TOPCon cells is around 28.7% which is much higher than 25% of PERC and 27.5% of HJT. It is very close to ideal efficiency limit of c-Si, 29.43%. Thus, TOPCon cell has higher potential to develop. In the past few years, had great achievenments on N-type TOPCon solar cell. The efficiencies of TOPCon solar cells reach 24.5%. The new technology, J-TOPCon 2.0, apply the original POPAID (Plasma Oxidation&Plasma Assisted Insitu-doping Deposition） technology. Compare with J-TOPCon 1.0, 2.0 reduces the processing steps and achieve the higher efficiency and yield. J-TOPCon 2.0 curtail 3 manufacturing processing steps. The single-side surface poly-Si deposition and doping of poly-Si can be completed in one step which can further decrease the cost. J-TOPCon 2.0 achieves 24.5% solar cell efficiency by omitting the etching step of wrap-around Poly-Si which avoid the damage of pyramids of the surface. TOPCon module produces more electricity per watt compared with p type. Each 10W increment on the module will bring 0.05RMB/W premium. In the future, the LCOE of TOPCon modules will be continuing reducing to achieve the same cost of PERC modules.
