Corporate responsibility

Sustainability is competitive

In Germany, it is already possible to use green electricity on an industrial scale at competitive prices, something which Hanwha Q CELLS has been demonstrating since 2009. Production at its Thalheim plant is powered exclusively by renewable energy sources. The Berlin plant made the change in 2011 and is now also supplied with green electricity. The company has managed to reduce CO2 emissions by 90 per cent at its German production sites compared with 2008.

Hanwha Q CELLS aims to ensure transparency when describing the impact that its solar cell and solar module manufacture has on the environment. In 2011, a project was launched to produce life-cycle assessments for our products. Main indicators are the carbon footprint and the energy payback time. The datas will be updated on a yearly base.

Link to life-cycle assessment

It is our aim to check business activities systematically for possible environmental risks and vulnerabilities and identify potential for optimisation. 

Efficient environmental controlling

Successes in environmental protection can also be measured and managed. Hanwha Q CELLS regularly analyses environmentally relevant data and costs to produce benchmarks that demonstrates the company's environmental efficiency. Such analyses focus on the entire value creation chain involved in the production of a solar cell or module and encompasses the assessment of whole systems. For Hanwha Q CELLS, environmental controlling begins with sustainable procurement and ends with the recycling of end products.

The input-output analysis summarises the annual flow of our main materials. Data is reviewed on a monthly basis to detect any impact on the environment in good time and increase the standard of the environmental protection on site.

Energy- and resource management

The basis for efficient energy and resource management is a transparent database. The instruments to provide such a database consist of environmental controlling and our process monitoring system, introduced in 2011. Energy analyses based on these data are carried out on a continuous basis and used to identify saving potentials. After an internal evaluation, our specialists enter the findings into different targets and actions.

Environmental objectives

The basis for defining objectives and determining measures is a fixed process to identify environmental and energy aspects and establish findings from energy and resource management. Identified environmental and energy aspects, defined objectives and approved company policy are closely interrelated.

Environmental and energy aspects

Making ecologically sound use of raw materials increases our efficiency and preserves natural resources. Hanwha Q CELLS identifies its environmental and energy aspects and environmental and energy impact on a yearly basis according to the specifications outlined in DIN EN ISO 14001 and DIN EN ISO 50001.


The avoidance of waste is our highest priority, followed by potential recycling before disposal. We have set ourselves targets in this respect which go beyond legal requirements. After putting into operation a flue gas purification system (SCR system) at our Thalheim location in March 2010, we managed to reduce chemical waste at the site by 7,000 t. The system is based on a treatment of nitrous oxides (NOx) using a thermal, catalytic process. In addition to avoiding waste, any waste produced is recycled using an environmentally friendly process. The recycling rate gives an indication of how much waste is recycled in an environmentally friendly way as a percentage of all the waste produced. The rest of the waste is disposed of according to regulations. We verify this process on a regular basis by carrying out audits at the waste management company’s actual facilities.

CO2 emissions

When calculating CO2 emissions we take into account direct emissions (Scope 1), indirect emissions (Scope 2) and emissions from employee transportation (Scope 3). Since 2010, we have also included emissions produced by the company vehicle pool. The data refer to the Thalheim (Germany) location and the Cyberjaya (Malaysia) location.

Exhaust emissions from production processes (Scope 1):

Exhaust treatment systems have been installed with state-of-the-art technology in our production facilities. Voluntary monitoring of our exhaust emissions using an emission inventory allows us to respond quickly to any changes. The emission inventory is updated and the acquired data analysed on a regular basis.


Exhaust emissions from power generation (Scope 2):

The emissions produced while generating electricity are not produced directly at the Hanwha Q CELLS location, but from the respective electricity producer’s facility. An electricity producer may generate emissions by burning coal, for example. In order to reduce emissions, Hanwha Q CELLS has been using CO2-free electricity for manufacturing processes at its Thalheim plant since 2009. Unfortunately, we are not able to do the same yet at our Malaysian plant due to the local power supply networks in the country.

Exhaust emissions due to transport and travelling on company business (Scope 3):

For a globally active company such as Hanwha Q CELLS, business trips worldwide are unavoidable. In cooperation with the German railway company, Deutsche Bahn, we offer our employees a jobticket, an inexpensive, environmentally sound way of commuting to work. For our own short-notice deliveries, we use forwarding agents who operate in the region. We ensure that we make optimum use of forwarding service capacities. 80 per cent of our shipments are collected by our customers themselves on site.

At Hanwha Q CELLS, water mostly used during production process. The wastewater produced is cleaned in water treatment systems. The cleaned water is then fed back into the production process. This system allows Hanwha Q CELLS Thalheim (Germany) an Hanwha Q CELLS Cyberjaya (Malaysia) production locations to reduce wastewater by about 30%.

Use of resources

Responsible handling of resources is assured at Hanwha Q CELLS. That’s why we further develop our processes and the equipment and materials that we use in production on a continuous basis. In doing so, our main objective is to reduce the use of raw materials, additives and consumables.

Dealing with Hazardous substances

When new hazardous materials are introduced into production processes, our hazardous material management team checks to see if a substitute material could be used. All potential risks from the use of materials is checked and assessed right up to waste disposal.


Life-cycle assesment

A life-cycle assessment is a systematic analysis of a product’s environmental impact during its entire life cycle. This includes all environmental impacts during raw materials production, production, usage, transport, product disposal and associated upstream and downstream processes, such as the production of raw materials, additives and consumables.

The environmental performance of Q CELLS products over their entire life cycle is of prime importance to us. By including information from processes which are upstream and downstream from actual production at Hanwha Q CELLS locations, we also take responsibility for environmental impacts which occur in the supplier chain and during disposal. We are working to create life-cycle assessments for our products during all stages of their life, from silicon extraction, wafer manufacture and cell production through to module manufacture and the use of Q CELLS solar modules in ground- and roof-mounted systems. These assessments take into account the production and packaging materials used, energy consumption, transport distances, emissions and waste produced at each life cycle stage. This enables us to obtain a complete picture of the environmental impact that our products have and to work actively on providing improvements. Using an assessment software application and a scientifically sound database allows us to ensure that findings are comparable and based on solid facts. Results from this analysis comprise a comprehensive CO2 footprint and energy-returned-on-energy-invested times. If we take a reference value, it is clear that Q CELLS solar modules are more energy-efficient and significantly more climate-friendly than the average module. Our energy-efficient solar modules thus allow us to help protect the climate as generating CO2-free electricity releases fewer emissions into the environment than fossil-fuel energy producers, for example. The transparent presentation of results is important to us, as understandable statistics play a significant role in promoting the changeover to renewable energy sources worldwide.


Energy Payback Time

The energy payback time of our modules installed on a representative roof system amounts 1.42 years. The energy payback time of our modules without system components amounts 1 year. The data includes all stages of the life cycle.

Solar Energy for Ethopia

In July 2009, two Hanwha Q CELLS technicians taught 25 college students in Addis Ababa the basic principles of solar cell physics and production.

In November 2009 and November 2011, two Hanwha Q CELLS employees travelled to Ethiopia once again to train 25 solar technicians in Rema and Hawassa. Since 2007, Hanwha Q CELLS has provided patronage for the International Solar Energy School in the country, which is managed by the Solar Energy Foundation. The two Hanwha Q CELLS technicians arrived with solar cells, measuring devices, cables, soldering irons and comprehensive visual aids relating to photovoltaics and successfully taught the basics of solar electricity generation theory and practice within one week. After completing their training, the ‘Rural Solar Energy Managers' trained through this support programme now work in solar centres across the country, where they offer financing, installation and maintenance of small rooftop systems.

In a country where less than one per cent of the population has access to electricity, solar power, stored in a car battery, makes a huge difference by providing electric light. Solar electricity allows people to read, sew, cook, draw and listen to the radio after dark. Progress is thus being achieved.

Since 2012, Hanwha Q CELLS has been assisting in a construction project to provide a solar-powered water supply system to the Ethiopian mountain village of Rema. The old diesel-powered generator that used to pump the water from the well in the valley to the mountain village had broken down in autumn 2011. Ever since the people of Rema had to walk on foot scrambling an altitude of 400 m to get fresh water. In addition to supplying solar panels, Hanwha Q CELLS collected 8000,- € from an in-company donation to help install a solar-powered water pump. The Q CELLS solar modules will make the water flow uphill again.

Solar Energy Foundation

The Solar Energy Foundation´s principal aim is to promote development aid. This primarily involves combatting proverty through the use of environmentally friendly technology. The foundation also seeks to promote environmental protection, education and training. It runs solar electricification projects in Ethiopia under the slogan "Light for education" and maintains a school for solar technicians in Ethiopia. Hanwha Q CELLS supports the foundation's work with financial contributions and by sending trainers to Ethiopia.

Solar taxi

We were very much inspired by the Swiss adventurer and climate activist Louis Palmer’s idea of traveling around the world using solar energy, because it shows how solar mobility is possible in the future. That's why Hanwha Q CELLS is supporting the Solartaxi on its journey around the world, during which it will pick people along the way and give them a lift, thereby promoting the use of solar energy.

Fairness, Training and Responsibility

Fairness, training and responsibility are corporate values that we take as seriously as we do as performance, efficiency rates and quality.



Training and advanced training

Fairness, training and responsibility are corporate values that we take as seriously as we do as performance, efficiency rates and quality. We use international standards to guide us, such as the Universal Declaration of Human Rights by the United Nations, the European Convention for the Protection of Human Rights and Fundamental Freedoms and the principles of the Global Compact of the United Nations.

Knowledgeable, committed and motivated employees are the basis of our success. That’s why we attach great importance to our employees’ expertise. In 2013, a total of 689 employees took part in 169 training events and 3,523.25 hours of training. This included legal training for managers as well as the training of auditors.

Q CELLS had contracts for a total of 33 trainees and students in four training programmes and three student programmes in 2013. Students receive optimum grounding for a successful start to a career in the solar industry in the twelve outstandingly equipped specialist study rooms at our in-company training centre. One of our trainees was awarded the prize for the best machine and systems operator by the Halle-Dessau District Chamber of Commerce and Industry in November 2009.

Our social responsibility extends to initiatives far beyond the region, as can be seen from our involvement in the Solar Energy Foundation.

Computer training for disabled people

In cooperation with charitable organization Diakonieverein e.V. Bitterfeld-Wolfen-Gräfenhainichen, we carried out an advanced training project with five young mentally and multi-handicapped people in 2010. One of our trainers taught participants how to use calculation and text editing programs at our in-company training centre, aided by business administration trainees.

Career advancement and familiy life

Our employees are increasingly focussing on finding a balance between their career and family life. Employees shouldn’t need to choose between a child and a career. We'd like them to combine the two, so that our employees are able to fulfil their personal and professional responsibilities in equal measure. Depending on the job and place of work, we thus offer a range of different working-time models, such as trust-based working hours, flexitime and a one-year extension to parental leave involving part-time employment and telecommuting from home. In 2010, we set up a day-care centre near the company with 20 places for our employees’ children in cooperation with the town of Sandersdorf-Brehna.

Emergency preparedness and response

Establishing organisational regulations has enabled us to create the required conditions for Hanwha Q CELLS to also lead the way in company healthcare and work safety in terms of quality and performance. It is our strategic goal:

1. To ensure that Hanwha Q CELLS employees are healthy and fully fit for work and that no work accidents or occupational diseases occur (target = zero)

2. Our machinery and equipment are scrutinised with regard to their safety-related layout, safe operation and minimisation of impact due to breakdowns thanks to organisational hazard prevention measures.

This allows us make use of our machinery and equipment in line with the latest safety engineering standards when planning, setting up, operating and shutting down our equipment and machinery.
