BISOL Group is offering a complete range of solar solutions available in more than 90 countries. In the last 15 years, we have increased the production capacity of BISOL 6 times, and in the last 12 months, we have replaced almost all machines with state-of-the-art automated machinery from most renowned world providers and further improved them by our innovations.
With traceability to the best quality.
BISOL Production uses only top-notch components that ensure higher energy yields and lower degradation throughout the life of a solar module. Continuous product monitoring is very important therefore we designed a unique custom-made tracking system to offer us, among other information, complete module traceability with QR codes and help us monitor all module data on workstations. This means that within the production we can scan the QR code on each module and make sure that we used the best materials and that we have taken all the essential steps for a superior product.
The highest standards in all production processes.
Top-quality products are a reflection of the highest industry standards and the strictest quality criteria, under which we operate at all stages of the production process.
Cell stringing is a process, where time and temperature correlation define the quality of the solder joint.
Lay-up is another robotic automated process, which provides accurately positioned cell strings and where stations are equipped with cameras for the robot to eliminate the strings that do not meet the quality criteria.
Bussing is one of our latest robotic processes, which was introduced with half-cell technology.
EL Testing shows micro cracks, as well as visual irregularities. It is important to check this before lamination when all defects can still be repaired. We perform the test on each module that went through our production, which we can also prove through our unique tracking test.
Lamination is probably the most important step in the production of a solar module. We use top-notch EVA foil and our lamination time is much longer than the industry’s standard, which is reflected in better performance and lower degradation of the module.
Trimming is a process after lamination and before framing when the excess material is cut off from the module. Immediately after trimming, each solar module in the production of BISOL is re-inspected so that in the event of errors, we can react immediately and thus prevent serial production problems.
The framing machine for modules has been specially designed for the production of BISOL. Silicone is applied along the entire length of the aluminum frame, although there are cheaper alternatives, as our tests show that this is the only way to ensure our standard of the durability of solar modules.
The junction box that we use in BISOL is bigger, non-potting, and more expensive. The main advantage is a possible diode exchange inside the junction box - instead of changing the whole module - and a clip system for inserting the ribbons, which is much more fail-proof than welding. We didn't have any bigger failure issues with this type of junction box in 15 years.
Flashing is a process of scanning of modules' power. With all BISOL modules, flash power exceeds the nominal by up to 5 Wp, which can be proven by the data measured on each module.
Sorting modules not only by power output but also by voltage and current, assuring you get the best performance for what you paid by minimising mismatch losses on a solar power plant.
The packaging system in BISOL production ensures that there are no fingerprints or dirt on the modules. We designed the packaging to produce as little waste as possible while ensuring flexibility and stability. We currently sell our modules in more than 90 countries around the world, so packaging robustness is extremely important.
BISOL is putting great efforts to keep the company, the products, and the brand distinguishable and prevailing over the competition. But mainly to contribute to society – to create a greener environment and future energy independence by continuously investing in technology, developing visionary products, and increasing returns from photovoltaic investments.
