Our new I-V curve tracer can measure "high-efficiency solar cells" such as N-type, half-cut cells, and N-type back contact.

Recently sold high-efficiency solar cells PVA14300R, PVA18340, PVA11270, and PVA14301 can be measured using I-V measurements.

In recent years, there have been reports of cases where I-V curves cannot be measured for high-efficiency solar cells (such as N-type and half-cut cells) using products from other companies or the old model Epsilon 1000 (PVA14300) PV analyzer. However, it is possible to measure them using the current Epsilon 1000 (PVA14300R), Epsilon 1500 (PVA18340), Gamma series (PVA11270, PVA14301), and Delta (PVA11272) PV analyzers, which will be explained in this document.

CLT, which has been widely adopted in the construction field, is now expanding its applications into the civil engineering sector. The "Hyper CLT Mats" are civil engineering CLT products that utilize wood CLT as temporary materials. Traditionally, steel plates have been the mainstream choice for temporary roads, access routes, and heavy machinery yards. The Hyper CLT Mats introduce a new option of "wood" to that market. The 5x10 mats weigh approximately 230 kg, making them lightweight and easy to install and remove with small machinery, with a maximum capacity of 40 mats on a 10-ton truck. They also have advantages in terms of workability and transportation efficiency. Moreover, they offer added value that can only be achieved with wood, such as glare reduction, noise control, CO2 fixation, and consideration for aesthetics. This product is expected to be a new proposal for not only construction companies but also building material firms, lumber companies, and material trading companies. It is a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS, with the registration number "TH-250021-A." The use of wood is not limited to construction anymore. The utilization of Hyper CLT Mats is expanding as a new market that connects civil engineering and wood.

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.
