As solar energy becomes increasingly popular, more homeowners and businesses are considering solar rooftop systems as a viable way to reduce electricity bills and contribute to a greener environment. However, one of the most important factors in this decision-making process is understanding the cost of solar rooftop system. This blog will break down the factors that influence the cost and provide an overview of current pricing in India.
Factors Influencing the Cost of a Solar Rooftop System
1. System Size (Capacity)
The capacity of the solar rooftop system, measured in kilowatts (kW), is a primary factor affecting the overall cost. Larger systems generate more electricity but come with a higher upfront cost. A typical residential solar rooftop system ranges from 1kW to 10kW.
2. Type of Solar Panels
The type of solar panels you choose will also impact the cost. The most common types are:
- Monocrystalline Panels: More efficient and expensive.
- Polycrystalline Panels: Less efficient but more affordable.
- Thin-Film Panels: Lightweight and flexible but generally less efficient.
3. Inverter
The inverter is essential for converting the DC electricity generated by solar panels into AC electricity for household use. The choice between string inverters, micro-inverters, and hybrid inverters can influence the overall cost and efficiency of the system.
4. Mounting Structure
The mounting structure holds the solar panels in place. The cost depends on the material (usually aluminum or galvanized iron) and the complexity of the installation.
5. Installation and Labor Costs
Installation is a critical component of the overall cost. This includes design, installation, and commissioning, ensuring the system operates safely and efficiently. Installation costs can vary depending on the complexity of the project and the location.
6. Battery Storage (Optional)
For those who want to store excess solar energy for use during non-sunny hours, adding a battery storage system will increase the cost. This option is particularly useful for areas with frequent power outages.
7. Government Subsidies and Incentives
The cost of a solar rooftop system can be significantly reduced by taking advantage of government subsidies and incentives. The Indian government offers various schemes that can offset a portion of the installation cost, making solar energy more affordable.
Cost Breakdown of Solar Rooftop Systems
The cost of a solar rooftop system varies based on its size, components, and installation complexity. However, there is a general standard for calculating the cost of a solar rooftop. A high quality, well assembled and sturdy solar rooftop system costs around INR 65,000 per kW. Which means that the cost of a 3kW solar rooftop system should be around INR 2,00,000 and the cost of a 5kW system should be approximately INR 3,35,000.
To further understand the cost of a solar rooftop, you can refer to the table below which gives the percentage wise breakdown of the amount spent for each of the solar rooftop components.
Cost of 1kW Solar Rooftop
| Components | Cost (% of Total Spend) |
| Solar Panel + Inverter | 53% |
| Cables, Wires & Accessories | 31% |
| Mounting Structure | 8% |
| Installation | 8% |
Why the Investment is Worth It?
Despite the initial investment, solar rooftop systems offer significant long-term benefits. The potential savings on electricity bills, coupled with government incentives, make it a cost-effective solution for energy needs. Here’s why investing in solar is worthwhile:
- Reduced Electricity Bills: Solar rooftop systems can drastically reduce or even eliminate your electricity bills.
- Environmentally Friendly: Solar energy is a clean, renewable resource that reduces your carbon footprint.
- Energy Independence: By generating your own electricity, you are less dependent on the grid, which is especially beneficial during power outages.
- Increase Property Value: Homes with solar installations tend to have higher property values due to the added benefit of reduced energy costs.
The cost of a solar rooftop system in India varies based on several factors, including system size, type of panels, and installation complexity. While the initial investment might seem significant, the long-term benefits—such as reduced electricity bills, environmental impact, and potential government subsidies—make it a smart choice for many homeowners and businesses. When considering a solar rooftop system, it’s essential to get multiple quotes, assess the quality of components, and factor in the available incentives to make the best decision for your energy needs.
