About

GregTech Solar Expansion expands the solar energy branch of GTCEu Modern with a structured multi-tier progression from LV to ZPM.

Solar Panels do not simply generate a fixed amount of energy. Their actual production depends on environmental conditions such as sky access, time of day, weather, biome, and dimension.

The built-in GUI makes the system transparent: you can see stored energy, current generation, panel integrity, actual EU/t and amperage delivered to the network, as well as a detailed breakdown of every factor affecting production.

The mod is designed to fit naturally into GregTech progression while providing extensive configuration options for both regular players and modpack creators.


Features

  • Solar Panels from LV to ZPM
  • Solar Cells and Photoactive Layers with tier-based material progression
  • Dynamic solar generation affected by:
    • Sky access
    • Time of day
    • Weather
    • Biome
    • Dimension
  • Fully redesigned Solar Panel GUI
  • Compact and Detailed display modes
  • Progress bars for:
    • Stored Energy
    • Generation
    • Integrity
  • Real network output display showing actual EU/t and amperage
  • Configurable Base / Overdrive output modes
  • Detailed generation tooltips showing individual multipliers and final output
  • Color-coded multiplier feedback:
    • White = 100%
    • Green > 100%
    • Orange = 1–99%
    • Red <= 0%
  • 4 module slots prepared for future upgrade mechanics
  • Full English and Russian localization
  • Integration with GTCEu harvesting rules

Configuration

GregTech Solar Expansion includes a built-in configuration screen:

Mods -> GregTech Solar Expansion -> Config

You can configure:

  • General solar generation conditions
  • Individual settings for every Solar Panel tier from LV to ZPM
  • Base and Overdrive output amperage for every tier
  • Biome generation multipliers and overrides
  • Generation multipliers for:
    • Overworld
    • Nether
    • End
  • Custom dimension overrides
  • Identifiers from other mods and datapacks

Configuration changes are applied without restarting the world.

In multiplayer, gameplay configuration is server-authoritative:

  • Operators can edit gameplay settings
  • Other players automatically receive the current server settings in read-only mode

This allows solar progression and balance to be adjusted for individual worlds and modpacks without modifying the mod itself.


Requirements

  • Minecraft 1.20.1
  • Forge 47.4.0
  • GTCEu Modern 7.4.x or 7.5.x

Tested and verified on:

Minecraft 1.20.1 + Forge 47.4.0 + GTCEu Modern 7.5.x


Development Status

GregTech Solar Expansion is still in active development.

Planned future development includes:

  • Functional upgrade modules
  • Solar Panel degradation and Integrity mechanics
  • Further recipe and balance adjustments
  • Additional solar-related content

The current module slots, Integrity system, generation calculations, and configuration system provide the foundation for these mechanics.


Full Changelog

0.2.3

Release note

  • Version 0.2.2 was skipped; all changes prepared for it are included in 0.2.3.

Added

  • Built-in mod configuration screen available through Mods -> GregTech Solar Expansion -> Config.
  • Server-authoritative configuration editing and synchronization:
    • Operators can change gameplay settings in multiplayer.
    • Other players receive the current server settings in read-only mode.
  • Editors for general generation conditions, per-tier panel settings from LV to ZPM, biome overrides, and dimension overrides, including identifiers from other mods and datapacks.
  • Validation, Apply, Cancel, and Reset to Defaults controls for in-game configuration.
  • Separate configurable Base and Overdrive output amperage for every panel tier.
  • The selected output mode is stored independently for each Solar Panel and controls actual energy transfer.
  • Configurable generation multipliers for the Overworld, Nether, End, and custom dimensions.

Changed

  • Configuration changes now take effect without restarting the world.
  • Generation caches are refreshed automatically when configuration changes.
  • Stored energy is clamped when buffer capacity is reduced.
  • Generation now safely combines sky, time, weather, biome, dimension, module, and integrity multipliers, including bonuses above 100%.
  • Solar Panels now follow GTCEu harvesting rules and its requireGTToolsForBlocks setting:
    • Wrench only by default.
    • Wrench or Pickaxe when the setting is disabled.
  • Updated textures for Solar Panels, Solar Cells, and Photoactive Layers.
  • Updated the HV Photoactive Layer recipe:
    • Fine Naquadah Wire replaced with Fine Niobium-Titanium Wire.
    • Gallium Arsenide Plates replaced with Ultimet Plates.

Fixed

  • Fixed generation bonuses above 100% being ignored.
  • Fixed displayed combined percentages disagreeing with configured generation factors after integer EU/t rounding.
  • Improved dimension status reporting when generation is disabled by a non-positive multiplier or blocked by the sky-access check.

Localization

  • Added Russian and English text for the configuration screen, validation messages, Base/Overdrive modes, and dimension generation status.

0.2.1

Fixed

  • Solar Panel assembler recipes now correctly accept one of two soldering fluids through the #gt_solar:solar_soldering fluid tag:
    • gtceu:tin
    • gtceu:soldering_alloy
  • Fixed mod version substitution in META-INF/mods.toml:
    • Switched from ${file.jarVersion} to ${mod_version}.
    • Added processResources expansion in build.gradle.

Added

  • New fluid tag file: data/gt_solar/tags/fluids/solar_soldering.json.

0.2.0

Overview

This update introduces a completely new Solar Panel GUI and significantly expands generation telemetry and environmental logic.

The system now clearly shows real network output, generation factors, and per-block current limits, forming the foundation for future module and degradation mechanics.

Added

  • Completely redesigned Solar Panel GUI replacing the previous debug-style screen.
  • Aligned and reusable progress bars:
    • Stored
    • Generation
    • Integrity, currently fixed at 100%
  • Compact / Detailed view toggle.
  • 4 module slots in preparation for future module mechanics.
  • Output line showing actual EU/t and amperage delivered to the network.
  • Per-block current limit toggle (1A / 2A), saved in NBT.
  • Detailed generation breakdown tooltips for:
    • Sky access
    • Time of day
    • Weather
    • Biome
    • Dimension
    • Modules
    • Panel Integrity
  • Color-coded multiplier indicators:
    • White = 100%
    • Green > 100%
    • Orange = 1-99%
    • Red <= 0%

Changed

  • Generation logic expanded to account for weather, tier-based time of day, dimension, biome, and sky access.

Config / Balance

  • Added tier-based time-of-day multipliers.
  • Added biome-based generation multipliers with default rules and configurable overrides.

Localization

  • Full Russian and English localization for GUI and tooltips.

0.1.1

  • Updated recipes for compatibility with newer GTCEu releases.
  • Confirmed compatibility with GTCEu 7.4.1, 7.5.1, and 7.5.2.

0.1.0

  • Initial public-ready release.
  • Added multiple Solar Panel tiers with custom textures.
  • Added Photoactive Layers and Solar Cells.
