Hybrid Solar-Thermal Steam Power Generation with Parabolic Reflector and Solar Tracking System

Hybrid Solar-Thermal Steam Power Generation with Parabolic Reflector and Solar Tracking System

The Hybrid Solar-Thermal Steam Power Generation System is an advanced renewable energy project that combines solar photovoltaic (PV) technology, solar thermal energy, and automatic solar tracking to generate electrical power efficiently. The system demonstrates how sunlight can be utilized in two parallel ways—direct electricity generation and steam-based power generation—to maximize overall energy output.

The setup is presented on a clean white background, ensuring excellent visibility of all components and a professional laboratory-grade appearance. A compact ENGINEER’S BUTTY LAB BD logo is positioned at the top-left corner, scaled smaller than the system components to maintain branding without distraction.

System Overview

This hybrid system captures solar energy using a parabolic reflector that focuses sunlight onto a heat-absorbing copper pipe, converting water into high-pressure steam. The steam drives a mini steam turbine connected to a generator, producing electrical energy. Simultaneously, a solar panel with automatic sun-tracking generates electrical power to support control electronics, battery charging, and auxiliary loads.

An ESP-32 microcontroller manages system automation, tracking, safety, and monitoring.

Working Principle

1. Solar Tracking
   LDR sensors detect the strongest sunlight direction. Servo motors rotate the solar panel and reflector to maintain optimal alignment throughout the day.

2. Thermal Energy Generation
   The parabolic reflector concentrates sunlight onto the copper pipe and boiler, heating water to produce steam.

3. Steam Power Conversion
   Pressurized steam flows through the steam outlet tube to the turbine, rotating it and driving the generator.

4. Electrical Power Management
   Generated power is regulated using a charge controller, stored in a battery, and supplied to loads via an inverter.

5. Monitoring & Safety
   Temperature sensors, water detectors, and safety valves ensure controlled and safe operation, while system data is displayed on the LCD.
