Multi-dimensional analysis of array layout results – shadow analysis

Shadow obstruction is one of the core issues in the layout of photovoltaic arrays, and it is also one of the important indicators for evaluating the results of photovoltaic array layout. Candela3D enables multi-dimensional visualization and analysis of site-specific shading conditions, providing critical references for layout adjustments and design optimization of solar fields. 1. Display the shadows in the photovoltaic array field in real-time During any other operations, it can simultaneously display the real-time 3D shadows at a specified moment, supporting fixed, adjustable inclination, and horizontal single-axis (including inverse tracking). 2. When moving, copying, or deleting arrays, the array shadows should be displayed in real-time Unlike Figure 1, the shadow shown here: 1) is the shadow of the array when it is lowered to a height of 0 meters above the ground; 2) represents the shadow range line during a specific time period (from 9 a.m. to 3 p.m. on…

The flat single-axis column automatically adjusts and generates a site leveling plan

The length of a flat single-axis solar panel can exceed 100 meters, and even minor topographical variations can cause height differences of several meters between adjacent panels in the north and south directions, significantly affecting power generation. To adjust the height difference between adjacent supports in the north and south to an acceptable range (which may require a difference of 0.3 meters or less to reduce obstruction and facilitate the operation of cleaning robots), two approaches can be taken: (1) Adjust the bracket using the adjustment range of the column itself. However, the adjustment range of the column is limited, generally only 0.3 meters. (2) Level the site appropriately. Among them, site leveling can be approached from two perspectives: ① Taking into account the natural terrain, the site is leveled into a single slope with a consistent gradient and aspect. In layman's terms, it means the site is leveled into a slightly inclined plane that closely resembles the natural terrain. The advantage of…

Intelligent guided Planning of mountain roads

The planning of roads in Complex Terrain must meet requirements such as slope and turning radius. To facilitate users in efficiently completing related tasks, the following new features from Candela 3D have been added: Draw central line of the road: It can intelligently guide users to plan roads that meet the required slope and turning radius; Edit central line of the road: Modify the planned road; Import road centerline from CAD: The slope and turning radius of the imported road can be verified and edited to meet the requirements; Draw central line of the road: Edit central line of the road: Import the road centerline from CAD:

Multi-dimensional Analyze Array layout results – Statistical Analysis

Array layout is one of the core achievements in the design of photovoltaic power stations and the important part of the refined design of photovoltaics. Statistical analysis of the final arranged arrays can be used to check whether the results are reasonable and also provides a reference for the optimization of design results.Candela3D provides users with the following statistical analysis capabilities: 1. Array real tilt/azimuth The actual tilt/azimuth is relative to the nominal tilt/azimuth, mainly for complex terrains. Since no site leveling is performed, the long side of the array no longer remains horizontal, resulting in changes in the actual orientation of the array. For details, see the article "Are You Really Thoroughly Understanding the Familiar Tilt and Azimuth?". 2. Array nominal tilt/azimuth/base slope The nominal tilt/azimuth refers to the tilt and azimuth set during the layout. When the ground on which the arrays are located is horizontal, the real…

Based on the existing red line of the land, quickly start the plot selection

The site selection for projects in complex terrain typically involves several steps: 1）Confirm a preliminary red line range based on land use properties, property ownership, etc 2）Eliminate the Red line Range with too small Available Area 3）Eliminate the Red line Range with too low Available Ratio 4）Within the remaining Red line range, select the final Available range In this article, we will introduce how to use Candela3D to quickly screen land parcels based on existing red line of the land. It primarily covers steps 2) to 4). 1. Exclude the Red line Range with too small Available Area After excluding Restricted areas (such as roads, residential areas, etc.), red line areas with a certain low pressure value will be eliminated. 2. Exclude the Red line Range with too low Available Ratio Areas that pass the hill-shading analysis and are not within the prohibited range, when divided by the area of…

Check the array layout on real Terrain topography

During the construction, the PV array arranged on the survey and map is often found that there are many inconsistencies with the site conditions, resulting in rework or changes. With Candela3D, the array layout results are superimposed with the actual terrain topography, allowing for an early check on the consistency between the design outcomes and the on-site terrain. This minimizes discrepancies between the design and the actual site, significantly reducing the amount of design rework. 1. aerial imagery One of the outcomes of drone aerial imagery is the Digital Orthophoto Map (DOM file), which can be directly pasted into the 3D design file of Candela3D. For details, see "Candela3D | Restoring the Real Landscape of a Project Using Drone Imagery". 2. Satellite imagery When there is no drone flight imagery available, satellite imagery can be quickly used for mapping, and the mapping layer "landform" can be toggled on and off…

The report is highly appreciated, with multiple new charts added for mountain analysis

In the process of mountain PV plant design, it is necessary to analyze the mountain to form a general and comprehensive understanding of the project site situation. At present, in the design process of many mountain photovoltaic projects, the overall analysis of the mountain is often not paid attention to, and the site delineation and layout are only carried out after a general understanding of the slope aspect. The Candela3D mountain analysis function has been enhanced with the ability to generate 6 new charts and 24 new tables, providing comprehensive mountain analysis content and significantly enhancing the report. 1. Normal analysis of mountain body This function can divide the mountain into a certain number of groups based on average normal vectors. Each group is represented by its average slope angle and slope direction. 2. Analysis of mountain slope orientation 3. Analysis of mountain slope angles (including natural slope angles, east-west…
