The software will automatically perform these calculations. (2) The software is capable of generating multiple division plans based on the Foundation parameters set by the…

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…

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…

Comparison of different leveling schemes for horizontal tracker racks

1. Problem background The length of the horizontal tracker can exceed 100 meters, and even slight terrain undulations can cause excessive height differences in the north-south direction of the tracker; this can result in shadow obstruction and prevent the cleaning robot from moving. For this reason, adjustments need to be made to the racks to ensure that the height difference between adjacent racks in the north and south is within the Setting range (typically around 0.3 meters). At the same time, the adjustable range of the rack Pile is generally only around 0.3 meters, which inevitably means that the length of some Piles may not meet the requirements. Therefore, it is generally necessary to level the site. This article intends to compare the site leveling quantities of the following three site leveling schemes: Site leveling plan 1: only adjust the height of the rack above ground Site leveling plan 2:…

Crossing hills and avoiding potholes – optimizing array layout by controlling the difference in pile length of the array

In each layout area of a complex terrain project, there are inevitably a small number of prominent hills, pits, and steep slopes, which are time-consuming and laborious to identify and adjust manually. The new version of Candela3D introduces a "Maximum Pile Position Height Difference" parameter in the array layout interface, allowing users to automatically avoid these areas and select short arrays for filling based on the available space. 1. Prevent the layout of arrays across hillocks 2. Prevent arrays from being arranged across pits 3. Prevent arrays from being arranged across steep ridges This function employs automatic step-by-step avoidance and automatically fills appropriate arrays; compared to non-automatic avoidance, where screening is done through pile length differences after arrangement is complete, it saves time and effort, and the arrangement capacity is larger and more reasonable.
