In recent years, rooftop solar installations have gained immense popularity as a sustainable and cost-effective energy solution. However, to ensure a smooth transition to solar power, it is crucial to understand the concept of "sanctioned load" and its significance in rooftop solar applications. In this blog post, we will explore what sanctioned load is, why it is important, and how it affects the installation and performance of solar rooftop systems. Additionally, we will delve into load extension, uncovering its benefits and how it complements sanctioned load regulations.

What is a Sanctioned Load?

Sanctioned load refers to the maximum amount of electricity a consumer is authorized to draw from the grid. It is determined by the local electricity Distribution Company (henceforth referred to as DISCOM) based on factors such as the size of the premises and anticipated energy consumption. For rooftop solar installations, sanctioned load plays a vital role as it helps determine the capacity and size of the solar system required to meet the energy needs of the premises.

Let's look at an example to help you grasp this idea. Suppose your building has a sanctioned load of 50 kilowatts (kW). This means that the solar system installed on the rooftop solar system should be designed to generate a similar or lower capacity of electricity to match the sanctioned load. A system with a higher capacity may not be approved or may require additional approvals from the DISCOM. While sanctioned load sets the framework for solar rooftop installations, there are instances where loads surpass the sanctioned load limits. This is where load extension comes into play.

The Importance of Compliance with Sanctioned load for Rooftop Solar

1. Cost Savings: By installing a solar system designed to match the sanctioned load, consumers can optimize their energy generation and consumption, leading to potential cost savings on electricity bills.
2. Grid Compatibility Issues: Non-compliance with sanctioned load guidelines may lead to technical issues when connecting the solar system to the grid, resulting in inefficiencies and reduced performance.

The Role of Load Extension in Rooftop Solar

Load extension is the process of extending the sanctioned load to accommodate additional electrical loads without compromising the overall stability and safety of the system. The benefits of load extension in rooftop solar installations are manifold.

Firstly, it ensures that heavy-load appliances operate optimally, reducing the risk of damage or underperformance. Secondly, by integrating load extension, consumers can minimize their energy bills by utilizing excess solar energy generated during peak production periods. Lastly, load extension promotes a sustainable energy ecosystem, as it diminishes the need for additional non-renewable energy sources.

Calculating the Required Sanctioned Load

Now that we understand the importance of sanctioned load, let's explore how to calculate the required sanctioned load for a solar rooftop installation:

1. Assess Energy Needs: Start by determining your typical energy consumption by examining past electricity bills. Consider peak load requirements during high-energy usage periods.

2. Analyze Solar Potential: Evaluate the solar potential of your premises by considering factors such as roof orientation, shading, and available space for solar panels. Consult with solar energy professionals like PeriUrja Energy to estimate the solar generation capacity based on these factors.

3. Size the System: Based on your energy needs and solar potential, calculate the required solar system capacity. Ensure it matches or is lower than the sanctioned load specified by the DISCOM or get ready with your documents for load extension application.

4. Seek Professional Assistance from us: Engage with certified solar installers or energy consultants like PeriUrja Energy to help you design and install a system that complies with sanctioned load regulations and optimizes your energy production.

Conclusion

Sanctioned load serves as a guiding principle in solar rooftop installations, ensuring safe and efficient integration of solar energy into our daily lives. By understanding the significance of sanctioned load and its role in rooftop solar, consumers can make informed decisions regarding their energy needs, comply with regulatory guidelines, and achieve long-term cost savings. Additionally, load extension complements sanctioned load, enabling consumers to embrace heavy-load appliances while maintaining energy efficiency and sustainability.
