Piles driver machines for solar parks
In today’s world, terms such as “phenomena due to global warming”, “smog”, “extreme pollution” or “limited resources” are an important topic that made humanity – slowly but surely – to start reacting positively to many “green” technologies that produce energy without polluting and more, using resources provided by nature. A system with photovoltaic panels is an optimal option for generating electricity in a sustainable way.
Photovoltaic panels are one of the technologies that have grown in size in Europe over the last 10 years.
WALDEVAR, the company present on the market since 2011, specializes in renting pile driving equipment with applications in road infrastructure (national roads and highways), agriculture (viticulture), clean energy (photovoltaic panels) and drilling.
WALDEVAR HWL 400R is a semi-mobile crawler machine used for piles, various types of fasteners and drilling in various types of surfaces. The compact and robust design of the machine allows it to work easily on difficult terrain (gravel or rocks), rugged or even on a slope of up to 35 degrees, without its stability being affected.

WALDEVAR, the ideal solution for fixing photovoltaic panels on land
The equipment is extremely reliable and can be used in specific works for fixing photovoltaic panel systems in photovoltaic parks in renewable energy projects. Investment in photovoltaic panels has accelerated in Europe in recent years, and the development trend will continue in the long term given the European Union’s environmental protection strategy.
Operations that can be performed with the WALDEVAR HWL 400R include drilling with custom heads, fixing and removing the piles/posts with various sections in size and shape, along with inserting columns and dowels by twisting / positioning and inserting piles/posts or various dowels sections in size and shape.
Main types of photovoltaic panels
Monocrystalline panels – the source of the material for crystalline solar cells is represented by silicone oxide. It is reconditioned, melted, poured into ingots and portioned. The silicone cells are cut to a thickness of 100-180 micrometers. With their help light is converted into electricity.
Monocrystalline cells have an efficiency of up to 23%, and monocrystalline solar panels have an efficiency of up to 19%. In contrast, polycrystalline cells have an efficiency of up to 20%, and when integrated into a solar panel have an efficiency of up to 18%:
Ventilation is important to prevent additional efficiency losses due to overheating caused by too much light. Currently, monocrystalline panels fixed to the roof can produce 350 watts, while polycrystalline modules produce up to 265 watts.
Bifacial panels use an innovative technology through which crystalline cells can use light on both sides of the equipment. A clear plastic wrap or a layer of glass attached to the back of the panel helps to indirectly capture reflected sunlight. If the system is properly positioned, the additional efficiency obtained can be up to 25%. These panels can produce 375 watts, but at a higher price compared to conventional products.
Thin film photovoltaic panels are also available, which include semiconductors for electricity generation. This system can provide an efficiency of about 15.5% and can produce up to 420 watts. The thin film better protects the panels in case of high temperatures and allows better efficiencies during use compared to other types of photovoltaic panel systems.
Specialists recommended the choice of photovoltaic panels from internationally renowned manufacturers. Also, the installation works of the systems, whether we are talking about roof-mounted panels or large-area solar parks, must be carried out with the support of professionals in the field.
Renewable energy, increasingly important at EU level
Europe has an ambitious target for renewable energy consumption. By 2030, about a third of Europeans’ energy needs should be covered by green sources. Energy will be produced by each Member State, but the challenge is the equipment needed to turn natural resources into clean energy.
Most photovoltaic cells and modules are made in China, Taiwan or Malaysia, according to an EU report. The most efficient crystal cell technology is used by a small number of manufacturers in America and Asia.
An innovative cell project is being developed in Europe to convert 25.4% of solar energy into electricity. The current world record is 26.7%. If the technology proves its efficiency, we will also be able to have a significant market for the production of photovoltaic panels in Europe.
In 2019, the European photovoltaic market reached approximately 17 GW with a growth trend in the future.
Technology is becoming increasingly popular globally and the role of this segment has become increasingly important in the EU’s energy mix. In 2018, the production of electricity in the photovoltaic segment was 127 TWh, ie 3.9% of gross energy production in the EU.
Over the next decade we will see an increase in industry, especially in the area of self-consumption and roof-mounted photovoltaic installations. The photovoltaic sector was responsible for more than 117,000 jobs in 2018, and by 2030 should provide up to 300,000 jobs, according to the EU.
The progress of photovoltaic technology is significant if we analyze the production costs. Thus, between 2009 and 2018, the total cost for the production of photovoltaic modules decreased by 75% while the adoption rate increased steadily in the European market by 500 million consumers.
