Developing Future With Solar Energy
Assistant Manager, Technical Cell
Solar energy generation and utilization for mankind has been making headlines since the early 1930s. However, it indeed took more than 60 years to supply electricity to millions of human beings from renewable energy such as Solar. The world has shown its readiness to accelerate the transition towards global energy decarbonisation. Today human efforts are towards judicious utilization of finite fossil fuel and reduction in carbon footprints.
Solar energy can be considered as a never depleting source of clean energy for humans since the Sun still has more than 5 billion years of life according to NASA. Every 24 hours, enough sunlight touches the Earth to provide the energy for the entire planet for 24 years. As per some publications, "the Earth’s surface receives 120,000 Terawatts of solar irradiation, which represents 20,000 times more power than the whole planet needs.” This energy is renewable, inexhaustible & non-polluting. It is versatile and can be applied for small scale areas isolated from network to large scale energy generation. This gives the world the perfect reason to switch to Solar Energy!
The Government of India has set the target of installing 100 GW of solar energy by 2022, which has led to an unanticipated surge in solar power generation. This has further led to an enormous demand for solar panels, solar inverters, batteries, performance monitoring systems and not to mention, various special kinds of wires and cables suitable for their connections. These cables constitute a very small percentage of the total project cost, however, the type and quality of the cables selected for the solar application may directly impact the power output performance and system safety.
Solar cables popularly known as DC cables, have to withstand harsh environmental conditions and are generally placed at an isolated location. They have to survive constant high temperatures, UV radiations, ozone, mineral oils, acid, alkali, ammonia and fire risks with a life expectancy of 25 years. The quality, safety and profitability of a solar plant or project depends on the workmanship and efficiency of the components used. DC cables are the lifelines of Solar Power plants. Hence choosing an ordinary cable for such application may lead to high maintenance cost, reduced efficiency and compromise in fire safety.
In a rush to grab huge business opportunities, market shelves are filled with non-standard DC cables. Cables with look-alike constructions may absolutely be price competitive but cannot meet the required technical parameters and the adverse environmental condition. When the integrity of the whole project depends on these cables, it is meaningless to have price-oriented quality benchmarks for DC solar cables. We need to ensure the correct cable with the updated applicable standards and requirements.
RR KABEL offers Solar cable as per EN 50618 standard, meeting the most adverse environmental conditions. This cable is offered with Low Smoke and Halogen Free insulation and sheath materials. Electrolytic Tin coated copper conductor further adds to the non-corrosive properties and better solderability.
