Half-cell solar modules have solar cells that are cut in half, which improves the solar module`s performance and durability. Traditional 60-cell and 72-cell solar panels will have 120 half-cut cells and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the solar cells can produce more power.
Smaller cells experience reduced mechanical stresses, reaching a decreased opportunity for cracking. Half cut cell PV modules have higher output ratings and are more reliable than conventional solar panels.

Hotel LED to achieve energy efficiency
In the case of Philips' classic hotel lighting project, the Palacio de Isora in Tenerife, Spain, is in urgent need of finding an alternative to traditional halogen lamps in bedrooms.
Philips Lighting's solution is to replace traditional luminaires with LED products. Almost all of the hotel's 20 public areas use LED lighting. This functional and decorative lighting solution is equipped with a control system. Create different lighting scenes.
Smart lighting is also installed in each main room to control lighting and maximize energy savings. LED lighting requires only 12 W of power to produce the same brightness as a 35 W halogen lamp. This means that each room can not only save 66% of energy, but also reduce carbon dioxide emissions by 463 kilograms per year, reducing the cost of lighting for hotels by more than 60%.
At the same time, thanks to the average service life of 50,000 hours, LED lighting equipment requires very little maintenance, and maintenance costs can be saved by more than 30%. The installation of LED luminaires in the center of the ceiling dome of each bedroom not only reduces energy consumption by 88%, but also cuts an additional 4,269 kg of CO2 per year.
Refer to the "Architectural Lighting Design Standards", according to the same illuminance replacement principle for energy saving effect estimation and prediction, LED products can achieve more than 60% energy saving performance compared with traditional lamps, and can generate economic benefits in eight months to one year.
Hotel lighting needs more "art"
On March 16th, "China's Hotel Industry Green Lighting and Energy Conservation Standardization Establishment Forum", Li Xuliang, Chairman of Qinshang Optoelectronics, explained the cooperation concept between optoelectronic enterprises and hotels on green lighting renovation.
He said that optoelectronics companies can reach strategic alliances with designers to strengthen the technical exchange of LED lighting design, and provide cost-effective LED products to hotel owners, and provide professional technical support to the hotel.
In addition, lighting is the crowning touch of the hotel and a symbol of the hotel's cultural connotation. LED's precise light distribution technology and plasticity are more conducive to the hotel to create beautiful lighting effects. The green energy-saving features of LEDs greatly reduce the hotel's electricity costs and maintenance costs.
Huang Yumin, director of Guangzhou Guangying Space Lighting Design, said: “Designers are not only involved in the design of lighting projects, but the more important responsibility is to make the project results continue to add value in the future.â€
He pointed out that LED projects have more room for added value in terms of green energy efficiency and service life than traditional light source projects. However, he also bluntly said that the current LED technology is not fully mature, there are still many defects and even affect the design work, and many designers have doubts about LED.
Promote EMC opportunities
For the group hotel chain, its huge lighting system needs huge energy support, and energy saving and emission reduction has become a very urgent problem, which undoubtedly provides an opportunity for the EMC contract energy management model in the green lighting system. .
In the process of implementing the hotel EMC model, optoelectronics companies can cooperate with insurance companies to purchase product quality insurance and commercial credit insurance, eliminating the wariness of hotel owners, ensuring the “zero risk†of LED lighting scale promotion and maximizing profits. Minimize risk.
At the same time, in terms of energy-saving revenue sharing, third-party insurance companies can be introduced to cover the payment credit of the project, ensuring timely payment of accounts receivable.
In the EMC market case, the EMBT (Energy BT Management) model launched by Qinshang Optoelectronics has been well promoted. The EMBT mode flexibly combines the advantages of the EMC and BT modes. It improves the traditional EMC energy-saving measurement and cumbersome monitoring of the same-variable payment method, and determines the completion and acceptance of the project as a fixed node, and determines the owner and the operator at the node. Project energy savings, energy saving rate, and post-payment methods.
At the same time, Qinshang also transformed the project's performance rights and responsibilities into the traditional BT model, and improved the post-operation management with the BT-mode operation process, and transformed the determined energy-saving income into a fixed-rated payment behavior. This move not only retains the EMC model's “zero cost†characteristics for customers, but also follows the advantages of BT mode fixed payment, forming an energy-saving service installment payment. 
Hotel lighting has gradually become a new blue sea of ​​LED
[Source: Gaogong LED's "LED Lighting Channel", 2013, Issue 4 (Total Issue 40) Reporter / Li Jingyu] The new LED light source, known for its green energy saving, has traditional light sources in terms of saving electricity costs and lighting maintenance costs. The comparable advantages are gradually becoming the new darling of hotel lighting. According to a survey by the reporter, due to the huge potential of the hotel's green lighting market, lighting companies such as Philips, NVC, Qinshang Optoelectronics, and Sidon have laid out the hotel lighting market, which is regarded as a breakthrough in the LED indoor lighting market.
