Solar energy is increasingly becoming a vital part of India’s energy landscape. With plenty of sunlight throughout the year, the country is well-positioned to harness this renewable resource. However, the process of solar panel mounting in India comes with its own set of challenges, advantages, and disadvantages. In this blog post, we will explore these aspects in detail.
In India, a solar panel mounting future is bright and growing. You can generate electricity for free by using solar panels for your home or business. Currently, the rooftop solar panels convert about 20 percent of solar energy that falls on it into electricity. However, there are certain things should be considered before solar panel mounting.
Benefits of Solar Panel Installation in India
Environmental Benefits
- Reduction in Carbon Footprint: Solar energy is a clean, renewable source of power that helps in reducing greenhouse gas emissions.
- Sustainable Energy Source: Solar panels provide a sustainable way to generate electricity without depleting natural resources.
Economic Benefits
- Cost Savings: Despite the initial investment, solar panels can significantly reduce electricity bills over time.
- Government Subsidiary: The Indian government offers various subsidies and incentives to promote solar energy adoption.
Under the Rooftop Solar Scheme, the government offer the below subsidies for installing solar panels: For up to 2 kW – Rs. 30,000 per kW. For extra capacity up to 3 kW – Rs. 18,000 per kW. Total subsidy for systems larger than 3 kW – Maximum Rs. 78,000.
Technological Benefits
- Low Maintenance: Solar panels require minimal maintenance compared to other energy sources.
Energy Independence: Solar energy reduces dependence on imported fuels, enhancing energy security.
What are the Different Types of Solar Panel Mounting?
1. Sloped Roof Mounting System
Solar panels are often mounted on the sloping rooftops of residential buildings. There are several methods for mounting solar panels on these roofs:
2. Standard Rail System
In this system, rails are attached to the roof to support rows of solar panels. The rails are secured with anchors and bolts that penetrate the roof, providing strong and durable support. This method is known for its robustness and longevity.
3. Rail-less System
This system eliminates the need for rails, with hardware directly attached to the anchors and bolts. By removing the rails, this system reduces manufacturing and shipping costs and speeds up the installation process. It also allows for more flexibility in the orientation and number of solar panels, as there are no rails to constrain the setup.
4. Shared Rail System
In a shared rail system, the middle rail is shared between two rows of solar panels, which reduces the number of rails needed and minimizes roof penetrations. This method saves on materials and simplifies installation.
5. Flat Roof Mounting System
Flat roof mounting systems are typically used on commercial and industrial buildings such as workshops, garages, and offices. These systems require fewer penetrations compared to sloped roof systems.
Solar panels are usually tilted at an angle between 5 to 15 degrees to optimize electricity generation. The flat surface of the roof provides ample space, allowing for dual-tilt configurations to maximize energy output.
6. Inbuilt Solar System
The inbuilt solar system is ideal for new building constructions. In this system, solar panels are integrated into the building structure, eliminating the need for separate anchors and penetrations. This integration not only enhances the aesthetics of the building but also streamlines the installation process.
Challenges of Solar Panel Installation in India
High Initial Costs
- Capital Investment: The upfront cost of purchasing and installing solar panels can be high, deterring many potential users.
Space Requirements
- Rooftop Space: Adequate rooftop space is necessary for effective solar panel installation, which can be a constraint in densely populated urban areas.
- Land Use: Large-scale solar farms require significant land, which can be challenging to acquire and maintain.
Technical Challenges
- Efficiency Issues: Solar panels’ efficiency can be affected by dust accumulation, high temperatures, and shading.
- Grid Connectivity: Integrating solar power with the existing grid infrastructure can be complex and costly.
Regulatory and Policy Challenges
- Regulatory Hurdles: Navigating the regulatory landscape for permits and approvals can be time-consuming.
- Inconsistent Policies: Varying state policies and incentives can create confusion and uncertainty for investors and consumers.
Pros and Cons of Solar Panel Installation
Pros
1. Renewable Energy Source: Solar energy is inexhaustible and widely available.
2. Reduces Electricity Bills: Solar panels can drastically cut down electricity expenses.
3. Diverse Applications: Solar energy can be used for electricity generation, water heating, and even in transportation.
4. Low Maintenance Costs: Once installed, solar panels require minimal upkeep.
Cons
1. Weather Dependent: Solar energy generation is affected by weather conditions and is less efficient on cloudy days.
2. Storage Costs: Solar energy storage solutions like batteries are expensive.
3. Initial Investment: The cost of solar panels and installation can be a barrier for many.
4. Space Requirements: Adequate space is needed for installation, which can be a constraint in urban areas.
FAQs about Solar Panel Installation in India
What is the cost of installing solar panels in India?
The cost varies depending on the size and type of the system, but on average, it can range from INR 40,000 to INR 1,00,000 per kW.
Are there government subsidies for solar panel installation in India?
PM Surya Ghar: Muft Bijli Yojana is a government scheme that aims to provide free electricity to households in India.
How much space is needed for solar panels?
Typically, 1 kW of solar panels requires about 100 square feet of area.
How long do solar panels last?
Solar panels generally have a lifespan of 25-30 years with proper maintenance.
Can solar panels work during a power outage?
If connected to the grid without battery storage, solar panels will not provide power during a blackout. However, systems with battery backup can function independently.
Final thought
Solar panel mounting in India presents a promising avenue for sustainable energy, despite its challenges. The environmental and economic benefits outweigh the initial investment and technical hurdles. With supportive government policies and increasing technological advancements, solar energy is set to play a crucial role in India’s energy future.
