Within the overall cost structure of solar pv mounting kit the on - site installation labor costs are rising year by year. For large - scale ground power stations the installation teams staying on - site every day lead to continuous expenditures such as equipment leasing personnel salaries and project management.So then, finding the feasible ways that can make the installation period shorter has indeed become a direct way to enhance the profitability of the project.
The on - site working time for installing the solar pv mounting kit, which can be reduced by 30%, is not an unachievable aim but needs combined efforts in design, logistics and on - site implementation.
First, the first problem to be solved is the degree of pre-assembly in the design phase. The traditional practice is transporting all components in large quantities to the construction site in an open-air environment and then workers starting from the very beginning to assemble them. The efficiency of this model is to a great extent dependent on the weather conditions and the workers' skill levels. An effective method is to pre - assemble a great number of sub - modules in the factory to the greatest extent possible—for example, connecting columns and brackets in advance to form unit components, or pre - fixing guide rails to connecting pieces at standard intervals. When solar pv mounting kits are delivered as semi - finished modules, the on-site work turns into a simple module assembly rather than a complicated task of identifying and positioning individual components.
Second, people often underestimate how standardized fasteners and foolproof designs affect the installation speed. A typical mounting system may have up to a dozen different types of bolts, nuts, and washers. Therefore, workers have to stop a fair amount when installing to find and pick the appropriate parts.The accumulation of these seemingly insignificant interruptions may lead to the consequence of losing dozens of minutes of efficient working time every day.By standardizing the fasteners in the solar photovoltaic installation kit into two to three standard sizes and also incorporating color coding or designs to prevent reverse insertion, the cognitive load during operation and the possibility of installation errors can indeed be significantly reduced.
The matching between the order of logistics packaging and the on-site installation process also needs to be carefully looked into. Many times, the installation team has to look for the required components in several boxes just because the packaging is sorted according to the manufacturing process rather than the installation order.An optimized approach is that all the materials needed for the first stage are packed into the first batch of boxes which are to be opened in the order of installation tasks, and the materials of the subsequent stages are stored separately.This type of logistics method that is synchronized with the installation rhythm can reduce the time spent in looking for solar pv mounting kit materials by at least 15%, thereby directly influencing the overall labor time.
On - site positioning and measurement is also a major source of labor time consumption as well. The traditional setting - out, which demands that surveyors use total stations one by one to determine the coordinates of each foundation point, is especially time - consuming on complex terrains as well.Intelligent measuring devices having the RTK positioning function or solar pv mounting kit components with preset positioning templates can make the time needed for positioning a single foundation be reduced from several minutes to dozens of seconds.For those hundred - megawatt - level projects with thousands of basic points, the cumulative labor savings brought about by this improvement is quite considerable.
The selection and management of the installation tools are also of equal significance. Compared with the traditional manual wrenches, the pneumatic or rechargeable torque wrenches can reduce the time needed to tighten a bolt by approximately 70%.However, the disorderly tool management, like wasting time in seeking wrenches or changing sleeves, sometimes can offset the efficiency improvement brought about by the tools themselves.A dedicated tool vehicle is configured for each installation team, and wrenches of different torque levels are pre - installed in line with the tightening sequence of the solar pv mounting kit, so that it can be ensured that workers can obtain the appropriate tools at any time in each stage of the process.
The often - neglected soft factors in employee training and the fine - division of labor. Dividing the installation team into three distinct groups, each specifically engaged in basic construction, the installation of bracket assembly and module installation, and then having each group repeatedly do the same task for a long time can probably increase efficiency by about 25% compared with having all workers rotate to do all tasks.
