TaskMapper: Streamline Mechanical Activities During Solar Construction
A look at key mechanical activities in solar energy project construction, including installing mounting structures that house PV panels, and how TaskMapper simplifies monitoring, updates, and reporting for EPC contractors.
Overview of Mechanical Activities
In solar project construction, mechanical and electrical tasks are crucial for connecting PV panels to inverters, substations, and the grid. Effective task management and transparency are essential for successful execution and reporting.
Mechanical work involves installing mounting structures that house PV panels for the life of the project. The different types of mounting structures include:
Fixed-Tilt Mounting System
This system features a fixed tilt angle, usually oriented East-West. It is the simplest and most cost-effective panel mounting option.
Pros: Low initial cost, easy installation, ideal for large, open spaces with minimal shading concerns
Cons: Less efficient than tracking systems, does not adjust for the sun's movement, potentially reducing energy production
Installation Process: The installation process begins with site preparation, where the site is cleared and leveled, and concrete foundations are used if the soil is unstable. Piles are then marked, staged, and installed with precision, with alignment being checked for quality. Following this, rafters and purlins are installed to create the framework. Modules are mounted and secured either manually or with cranes.
Single-Axis Tracker
This system allows solar panels to rotate on a horizontal axis to follow the path of the sun, enhancing energy production.
Pros: Increased energy yield compared to fixed-tilt systems, effective in locations with significant seasonal variations in sun angles
Cons: Higher initial and maintenance costs, not suitable for windy or space-constrained locations
Installation Process: The site is prepared similarly to fixed-tilt systems, with additional considerations given to soil stability. Piles are accurately marked, staged, and installed, with quality checks performed to ensure proper installation. Bearing houses, torque tubes, motors, and ancillary components are then installed for the tracker system. Finally, modules are mounted and secured, with cranes used if necessary.
Dual-axis trackers are rarely utilized due to their high cost and complexity, making them a viable choice only when maximizing energy output is essential and justifies the extra expenses.
The primary trade-off between fixed-tilt and single-axis trackers lies in balancing higher yield against increased cost and complexity. In regions where labor and land acquisition costs are relatively low, fixed-tilt structures are preferred. To compensate for the lower efficiency of fixed-tilt structures, the DC capacity of the plant is usually oversized compared to its tracker counterparts. Typically, the DC to AC Wp ratio is 1.2x for fixed-tilt projects but might go as high as 1.4x.
Understanding these systems and their installation processes enables better management of the mechanical aspects of solar project construction, ensuring efficiency and effectiveness in achieving project goals.
