Topographical Survey

A topographic survey is the foundational step in any solar park project. This service involves detailed mapping of the land’s surface features, both natural and man-made, including elevation, slopes, existing structures, and vegetation. Accurate topographic data allows solar park developers to make informed decisions about site layout, drainage, and construction planning.
We use advanced DGPS and GIS technologies to perform precise topographic surveys, ensuring accurate and actionable data for site planning.

Pile Load Testing

  • Static Compression Load Test: This test applies a continuous, controlled vertical load on the pile to measure its compression-bearing capacity. It assesses the pile’s ability to withstand downward forces, ensuring the foundation can handle the weight of the solar structures over time.
  • Uplift Load Test: This test evaluates the pile’s resistance to upward forces, such as wind uplift, which can affect the stability of solar structures. It ensures the pile is securely anchored and able to resist forces that could cause it to lift from the ground.
  • Dynamic Load Test: In this test, a sudden load impact is applied to the pile to analyze its performance quickly. This test is efficient and often used to supplement the static load test, providing additional data on pile strength and behavior.
  • Lateral Load Test: Essential for areas with significant horizontal forces, this test evaluates the pile’s resistance to lateral pressure from factors such as soil movement or wind. It is crucial for maintaining stability against sideways forces.
  • Pile Integrity Testing : Pile Integrity Testing helps detect structural defects, discontinuities, and weaknesses in piles that may arise during installation or due to subsurface conditions. Ensuring the quality and soundness of each pile is vital to avoid costly repairs, prevent structural failures, and enhance the overall longevity of the solar installation.

Soil Thermal Resistivity Testing (TRT Survey)

Soil Thermal resistivity Testing Service (TRT Survey)
Soil thermal resistivity is a critical factor in solar park development, directly influencing the efficiency and longevity of buried electrical and thermal components. At Naksha Solutions, we provide specialized Soil Thermal Resistivity Testing to assess the soil’s ability to dissipate heat, which is crucial for the safe and effective operation of underground cables and other thermal infrastructure.
In solar parks, underground cables carry electrical loads that generate heat, which needs to dissipate effectively to avoid overheating. High soil thermal resistivity can trap this heat, leading to reduced cable efficiency, increased energy loss, and potential thermal failure. Testing soil thermal resistivity helps optimize site planning by identifying areas where soil treatment or specific cable layouts are required to enhance cooling and maintain energy efficiency.

Hydrographic survey/ Bathymetry Survey for Floating Solar Projects

Bathymetry, the science of measuring underwater depth and mapping underwater features, provides essential insights for project execution:

  • Underwater Topographic Analysis: Identifies underwater ridges, slopes, or submerged obstacles that could impact anchoring.
  • Water Depth Assessment: Helps determine the placement of platforms and ensures safe clearance for submerged components.
  • Safety and Risk Management: Evaluates water depth for flood preparedness, ensuring long-term operational stability.

Naksha solutions provide bathymetry survey services with precise bathymetric data collected through sonar  technology, EPC and designer can make informed decisions for platform design, anchoring, and installation processes of solar panel of waterbodies like ponds, dams, etc.. .This ensures not only operational efficiency but also safety and durability.
