Introduction
The Solar System Project is one of the most popular topics in 2025, combining science, sustainability, and innovation. For school students, it means making miniature working models of solar power systems. For homeowners, it refers to real-life solar rooftop installations that reduce electricity bills and promote clean energy.
This article covers everything about solar projects — from science fair ideas to actual rooftop solar setups with subsidy benefits.
What is a Solar System Project?
A Solar-System Project uses solar panels and sunlight to generate electricity or demonstrate solar concepts. Depending on the purpose:
- Educational: DIY models for school or college projects.
- Residential: 1 kW–10 kW rooftop installations for homes.
- Commercial: Larger solar power plants for industries, schools, or societies.
Types of Solar System Projects
1. For Students (Educational Models)
Students can design:
- Mini solar-powered cars.
- Solar water heaters.
- Solar garden lamps.
- Small working models of solar power plants.
2. For Homes (Rooftop Solar Projects)
Households install 1 kW–5 kW solar systems to save on electricity bills.
3. For Businesses & Institutions
Industries, schools, and housing societies install 10 kW–100 kW+ projects for large-scale power generation.
Top Solar System Project Ideas for Students (Science Fair & DIY)
- Solar-Powered Fan Model – Simple DC motor connected with a small solar panel.
- Solar Water Heater Model – Using black PVC pipes and a glass sheet to demonstrate heating.
- Solar-Powered Car – A small toy car connected to mini PV cells.
- Solar Light Model – Small LED connected to rechargeable battery & panel.
- Working Solar Power Plant – Mini model showing solar panels, inverter, and battery.
💡 These projects not only win science fairs but also teach renewable energy basics.
Solar System Project for Homes – Rooftop Installations
For homeowners, a solar system project usually refers to installing rooftop solar.
- 1 kW system – Runs lights, fans, and small appliances.
- 3 kW system – Ideal for a medium household.
- 5 kW system – Can power ACs, geysers, refrigerators.
Subsidy on Home Solar Projects (2025)
Under PM Surya Ghar Muft Bijli Yojana:
- Up to ₹78,000 subsidy available for 3 kW+ systems.
- Direct Benefit Transfer (DBT) ensures subsidy goes straight to consumer bank account.
Cost of Solar System Projects in India 2025
| System Size | Approx. Cost (₹) | After Subsidy (₹) |
|---|---|---|
| 1 kW | 70,000 – 85,000 | 45,000 – 55,000 |
| 3 kW | 1.8 – 2.2 lakh | 1.2 – 1.4 lakh |
| 5 kW | 2.8 – 3.5 lakh | 2.0 – 2.4 lakh |
| 10 kW | 6 – 7.5 lakh | 5 – 6 lakh |
Benefits of Solar-System Projects
- Cost Savings: Cut bills by up to 90%.
- Green Energy: Reduces carbon footprint.
- Educational Value: Helps students learn renewable energy concepts.
- Government Support: Subsidies & low-interest loans.
- Long Life: 25+ years of panel durability.
Government Schemes & Subsidies
- National Portal for Rooftop Solar: Central platform to apply for subsidy.
- PM Surya Ghar Yojana: Free electricity scheme up to 300 units.
- State DISCOM Schemes: Additional state-level subsidies available.
