With rising electricity costs and increasing environmental awareness, solar energy has become one of the smartest investments for Indian households and businesses. A 5 kW rooftop solar system is an ideal solution for medium-sized homes, offices, and small businesses looking to save on energy bills while contributing to a sustainable future.
Let’s explore how a 5 kW rooftop solar system works — step by step.
⚙️ Step 1: Solar Panels Capture Sunlight
The process begins when solar panels, usually mounted on the rooftop, absorb sunlight.
Each panel is made up of photovoltaic (PV) cells that convert sunlight into direct current (DC) electricity. The more sunlight your panels receive, the more power they generate.
💡 For a 5 kW system, you typically need around 12–15 high-efficiency solar panels depending on their wattage.
⚡ Step 2: Conversion from DC to AC Power
The electricity generated by solar panels is DC (direct current), but most household appliances use AC (alternating current).
This is where the solar inverter comes into play. It converts DC power into usable AC power, ensuring that your fans, lights, and appliances run smoothly on solar energy.
🔋 Step 3: Power Utilization and Storage
Once converted, the electricity can either be:
- Used instantly to power your home or office, or
- Stored in solar batteries for later use (especially useful during night hours or power cuts).
A hybrid solar system includes batteries, while an on-grid system feeds excess power directly to the utility grid.
🔄 Step 4: Net Metering and Grid Connection
In an on-grid 5 kW solar system, excess electricity is exported back to the power grid through a net meter.
This allows you to earn credits for the extra power generated, which gets adjusted in your monthly electricity bill — significantly reducing your energy costs.
💰 In some states, you can even earn from surplus power generation under the net metering policy.
🌤️ Step 5: Continuous Monitoring and Maintenance
Modern solar systems come with smart monitoring apps that let you track real-time performance, energy generation, and battery status.
Maintenance is minimal — just regular cleaning of panels and an annual inspection by your installer.
🌱 Benefits of a 5 kW Rooftop Solar System
- Saves up to ₹7,000–₹9,000 per month on electricity bills
- Reduces carbon footprint by over 6 tons annually
- Pays back the investment in 3–5 years
- Eligible for government subsidies under the PM Surya Ghar Yojna
