The Next Step in Solar Cell Efficiency - More Power at Low Light

PERC technology increases the overall panel performance by increasing a cell’s ability to capture light. 

Innovative total green energy solutions provider JLanka Technologies in another pioneering venture introduced the latest solar panel technology being used by their global partners Trina Solar which allows solar panels to be more efficient in their assigned tasks.

Trina Solar gives a “second chance” 

In traditional solar panels when an electron reaches the back surface of the panel it loses its ability to contribute to the electricity generation process. However, with Trina Solar’s Passivated Emitter Rear Cell (PERC) technology electrons now literally have a “second chance” to be actively involved in the electricity generation. The electrons work on a bounce back effect that brings them to the front of the panel periodically which generates more electricity. These efficiency improved solar panels are now being widely used across the world and have become an instant success due to their efficiency and high rate of productivity. 

Speaking on the launch of this innovative product, a representative from JLanka Technologies notes, “JLanka Technologies has always been a company known for its innovation and ability to bring sustainable energy solutions to Sri Lanka. With this new Trina Solar PERC technology the possibilities are endless, especially since we are a tropical country with sunshine for most of the year. The power generation capacities of the solar panels are greater with these panels and we look forward to many new customers benefiting by choosing this product as their energy solution.”


Explaining the technology - More power at Low Light

PERC technology will generate more current due to the reflection of  light at the backside of the cell.

Explaining the technology in laymen terms he added, “Imagine the difference between driving on a regular traffic-congested road and a highway. The efficiency is definitely higher on a highway drive that is also smooth and more productive in terms of time. This is the difference presented by the new PERC technology.”

 In traditional technology sunlight used to generate solar electricity can be categorized as shorter wave lengths light and longer wavelengths lights. Generally, shorter wave length light (blue) contributes more to generate solar electricity than longer wavelength light (red). When the sun is at an angle in the mornings and evenings and or cloudy days, blue light will be absorbed by the atmosphere as it has a longer path to travel to the Earth’s surface than when the Sun is directly overhead. This eventually drops the performances of solar cells. 

However, with PERC technology it increases the overall panel performance by increasing a cell’s ability to capture light. It creates a new layer between the top layer and the back layer of the solar cell structure. When an electron of a red light reaches this new layer, it will reflect the electron towards the top layer and gives the electron a second chance to generate current. This enables not just greater efficiency but also reduces temperature, and generates more power in weak light.

 A residential solar panel system generally consists of about 20-30 panels while an industrial set-up is made up of about 700. As each panel built with the PERC technology becomes more efficient, the entire system generates more power. As solar panels come with a 25 year warranty, it would amount to a large production of electricity over the years saving customers money and contributing greatly to environment protection. These are all benefits that JLanka customers who choose the latest PERC technology solar panels can enjoy.

 The latest solar panels built to PERC technology will be exclusively available at JLanka Technologies in capacities to suit both the domestic and industrial markets.

US & Europe Fire Safety standard solar solutions now in Sri Lanka

JLanka Technologies in pursuit of increasing integration, energy efficiency, environmental awareness, and technological advancements through its products and services is now advocating and empowering citizens on mitigating crisis and fire safety precautions.

“For the most part, the solar power industry is unregulated,” said the Technical Manager at JLanka, Channa Mudalige. “But there is a continuing upward trend for not just commercial users but for homes to opt for solar energy solutions and it is with this in mind that we’re now advocating and empowering them with the know-how on how to better prepare themselves in the event of a fire.”

Workshop for Firefighters 

As part of this unique initiative, JLanka hosted a workshop recently at the Kadawatha Arpico Super Centre. Invited to the workshop were firefighters and security officers from the same vicinity. 

Both as a Corporate Social Responsibility and a mandate of the company itself, JLanka Technologies has been hosting a series of seminars and workshops across the country in a bid to empower citizens with know-how and understanding of solar power, solar photovoltaic (PV) and fire safety measures. 

According to Nipun Silva, Safety Engineer of JLanka Technologies, SolarEdge offers a PV power harvesting system that consists of power optimizers connected to each module, a PV inverter and module-level monitoring. Additionally, SolarEdge systems have a built-in safety feature that reduces safety risks.

When power optimizers are connected to the PV modules, the modules continue in “operation mode” only as long as a signal from the inverter is constantly renewed. 

In the absence of this signal, power optimizers automatically go into safety mode, shutting down DC current as well as voltage in module and string wires.

The SolarEdge system, with the integral SafeDC feature, ensures complete safety for firefighters working with PV modules, eliminates the risk of electrocution, and is the only inverter solution that is certified in Europe as a DC disconnect.

Comply with Global Fire Safety Standards

In the United States, for example, the National Electric Code, NEC 2014 requires rapid shutdown of PV Systems on Buildings. As part of this requirement, DC voltage from 10 foot from the edge of the array to the inverter has to be lower than 30VDC within 10 seconds of rapid shutdown initiation. The SolarEdge solution complies with this requirement. 

Another example is the German application guide, VDE- AR-E 2100-712 requires, among other things, that after switching off the AC power supply, emergency forces will not expose themselves to the risk of direct contact with DC cables, which still carry a voltage greater than 120 volts DC.

Environment Concerns of Harley-Davidson - The King of the Highway Cruising Bikes!

Emission off-setted Harley Owners Group Tour of Sri Lanka

Harley-Davidson, the king of the highway cruising bikes, is the only company to survive the great depression. Founded in 1903, they are the pioneers in heavy weight motor cycles. All of their bikes has bigger engines, raising the concerns it has on environment. However, they have the utmost aim and objective about the environment to think differently to preserve and renew for long term success. Their manufacturing facilities always aspire to reach zero landfill status.

Manufacturing sites  of Harley Davidson are continually working to reduce the environmental impact of manufacturing and other operations, including on-going efforts to reduce waste and increase recycling and reduce water use and energy consumption.   Further, the manufacturing sites establish annual targets for energy consumption and seek year over year improvement.   

Harley-Davidson Sustainability: Preserve and Renew the Freedom to Ride

Everyone should be passionate about future generations of riders by sharing the Harley Davidson experiences that can be enjoyed.  The purpose is clear; that is to fulfil dreams of personal freedom.  Their sustainability vision is simple.;  present generation preserve and renew the freedom to ride.

Waste reduction and recycling plays a unique part in the field of environment. The wastes,  that released from a cement manufacturing company are used as fuel in the kilns and the remaining ash is incorporated in to the cement.  The Power train operations reduced waste and diverted more of that waste from landfill through both new recycle and re-use streams resulting in a waste to land fill decreasing to the percentage of 5.9%.

The power train plant could reduce the amount of trash sent to land fill by 24% through increased recycling.  A new container system that gives clear messaging where common items should go was introduced.  As a result , the amount of recycling increased to nearly 10,000 pounds in 2012, with the average amount of mixed recyclables increasing from around 680 lbs per month at the beginning of the year to an average of 800 lbs per month by the end of the year.  In the same way, approximately four tons of compostable material from the cafeteria is sent to an Urban Farm.  Harley-Davidson Museum’s restaurant began purchasing locally grown produce from the farm.

Usage of water is also another critical factor in relation to the environment.  They reduced the water intake by 1,166,000 gallons.  The water reductions were the result of the full implementation of a new powder coat system.  The new system uses far less water, pulling  water only when needed it versus using a continuous flow of water, which spilled unused water down the drain.  It also uses sensors that automatically take water in as needed and shut off when unused.

Improving Social Impact

Harley Davidson U.S. manufacturing sites establish annual targets for energy consumption and seek year over year improvement.  The completion of a new powder coat line that uses residual heat from baking ovens to warm the water for the power coat washers has increased energy efficiency in the site.  The conversion of the power coat operation from two lies to the new single system has reduced natural gas consumption by 32%.  In addition, it installed a new chilled water system, and the facility has been exclusively repair compressed air leaks throughout the entire plant.

Those sites successfully shed power during the summer to conserve electricity.  HVAC units were shut down on peak demand days which conserved electricity during the summer heat. Power shedding of electricity was 0.5 Mkw for six hours. This was done on six different days and supported demand management efforts of the local utility.  In addition, the plant ovens were shut down during non production times (weekends and holidays).  As a result, they saved natural gas consumption and reduction by 6.5%.

Harley Davidson provided some general tips to the employees and contractors on sites; to maintain vehicles properly, avoid spilling gasoline, refrain from fuelling when pump shuts off automatically , refuel vehicles after dark, conserve energy, not to over cool homes, turn off lights and appliances when not using.

Corporate Environmental Responsibility – Another Step to Save the Earth

Companies green washing themselves has become the latest trend in the corporate world.  New buildings of Toyota and Bank of America,  Gold-certified  by the US Green Building Council, and Nike aiming to be carbon neutral are some of the few examples of this green washing. Known as the Corporate Environmental Responsibility (CER), it is a branch of the popular concept of Corporate Social Responsibility. Instead of aiming to build a better society and doing their part for the society in large, companies mainly concentrates on minimizing the damage to the environment and protecting it.

Components of CER

There are few main components to make a CER policy of a company effective. Including, environmental commitment and awareness, stakeholder engagement, measuring, reporting and auditing, transparency, commitment to continuous improvement and going beyond compliance.  According to most environmental non-governmental organizations (ENGO),  fundamental difference in expected environmental performance for companies of different ownership structures and size is minimal, as the need for corporate environmental responsibility is independent of company structure or size.

Driving forces behind CER

There are several driving forces behind the evolution of CER; consumer activism, shareholder and investor pressure, and competitive advantage are a few. As a result of increased discussions on human rights, Consumers and employees, nowadays, are attracted more towards the companies with a green vision, making it one of the main reasons for them to focus more on their responsibility towards the environment. Unlike in the past, the shareholders now,  request companies on disclosure of  environmental risk, recognizing that environmental risk often translates into financial risk. Investors hesitate to lend money to environmentally doubtful projects, for example, which might bring huge clean-up costs and damage to the reputation.  Corporations are now recognizing the potential competitive advantage to be gained by responding to stakeholder expectations for environmental performance of the company as a whole, or of its products individually.

Blue Sky Award - to Apply New Technologies for Renewable Energy Utilization

Going with this concept of Environment Responsibility, Shenzhen International Technology Promotion Center for Sustainable Development with the help of United Nations Industrial Development Organization (UNIDO), Boao Forum for Asia and CRES  awards “Bluesky Award - Evaluation of Global Top Investment Scenarios to Apply New Technologies for Renewable Energy Utilization” to encourage companies to protect the environment. This international contest aims to demonstrate award-winning technology success stories to guide large-scale renewable energy applications in China and other developing countries to mitigate the effects of the supply shortage of conventional energy and greenhouse gas effects on the global climate. Since 2005, four sessions have been held, 38 technologies have been granted the BlueSky Award among numerous competitors from Germany, the United States, Canada, Russia, Belarus, Japan, Australia, Brazil, India, the Philippines and China.

Trina Solar wins the award

Trina Solar, one of the principal companies affiliated to JLanka Technologies and a global leader in photovoltaic ("PV") modules, solutions, and services, received the Blue Sky Award 2014 for Global Top Investment Scenarios to Apply New Technologies for Renewable Energy Utilization for its high efficiency crystalline silicon solar cells and Honey Ultra modules, proving once again to the world that they are the true pioneers in the industry.
