Project outline / simulation result summary
The setting outline and table of contents of the entire photovoltaic power generation simulation are described.
～ Project overview ～
Shows the location of the power plant of this project, meteorological data, etc.
~ System summary ~
Shows an overview of system settings for the entire project.
～ Summary of simulation results ～
The simulation results are briefly described. The PR value (Performance Ratio) is the actual amount of power generated with respect to virtual power (assuming that the amount of energy of solar radiation is converted to electricity without loss under ideal conditions). It is an index showing whether it can be obtained.
The higher this PR value, the higher the power generation efficiency.
Simulation factor, solar array / system characteristics
The parameters, solar array information, and array loss values set during the simulation are listed.
~ Simulation parameters ~
Shows details of the gantry and weather model.
～ Solar array setting ～
Shows details of modules and inverters.
~ Loss of solar array ~
Shows the loss rate derived from the array.
Simulation factor, solar array / system characteristics
The set loss values for AC wiring loss (inverter to transformer) and external transformer AC loss (transformer to transmission line) are listed.
~ AC wiring loss ~
Shows the loss value due to wiring from the inverter to the transformer.
~ External transformer AC loss ~
Shows the loss value due to wiring from the transformer to the transmission line.
Definition of the horizon
Details of horizon data near the power plant.
～ Solar orbit (altitude / azimuth) ～
In the graph, the vertical axis shows the solar luminosity and the horizontal axis shows the direction.
The area below the gray line displayed below the graph indicates that it will be shaded.
Definition of proximity shadows (shadows of adjacent pedestals and trees)
-Three-dimensional model of solar power plant and surrounding shadow factors-
This is a 3D model of a photovoltaic power plant that combines the created 3D terrain model and panel layout.
You can reproduce the effects of shadows in detail by installing trees and structures that are affected by shadows around them and performing simulations.
~ Loss rate due to shadows at each time ~
The graph shows the percentage of shadow loss that occurs at each time.
simulation result
Details of the simulation results and monthly / annual power generation are described.
-First year monthly power generation / first year monthly PR value-
The monthly power generation amount in the first year of power generation and the monthly PR value are shown in a graph.
-Monthly / annual power generation simulation results-
Monthly and annual power generation and PR values are quantified and shown in the table.
Breakdown of loss
Various losses occur when generating electricity. The loss value from the total power generation amount to the grid connection is subtracted to calculate the value close to the actual power generation amount.
~ Annual loss ratio ~
First, the top of the graph shows the loss values in the surrounding environment such as the amount of solar radiation and shadows.
Next, the loss value from the module and the loss value from the inverter are shown.
Finally, the wiring from the inverter to the interconnection, the loss value caused by the transformer is subtracted, and the actual power generation amount is shown.
Statistical Probability (P50-P90) Evaluation
In solar power generation, the amount of power generated depends on the weather conditions and dirt on the module.
In the statistical probability evaluation, the probability that power generation can be achieved is described.
