10 Essential Factors to Consider Before Buying a Solar Rooftop System in India
Introduction: As the world shifts towards renewable energy sources, On grid solar rooftop system have gained significant popularity in India. With its abundant sunlight and increasing environmental awareness, harnessing solar power has become an attractive option for many homeowners and businesses. However, before you make a decision to invest in a On grid solar rooftop system, there are several crucial factors to consider to ensure that you make an informed and cost-effective choice.
1)Energy Consumption Analysis: Begin by assessing your current energy consumption patterns. Analyze your electricity bills to understand your peak energy usage and seasonal variations. This analysis will help you determine the appropriate size of the solar system you need. A common practice is to aim for a system that covers 80-100% of your energy consumption to maximize your savings.
2)Roof Suitability and Space: Evaluate the suitability of your roof for solar panels. Factors such as roof orientation, tilt, shading, and available space are vital. A south-facing roof with minimal shading is ideal, as it maximizes solar exposure. Additionally, ensure that your roof can support the weight of solar panels. Consider practices like trimming trees or adjusting the panel tilt to optimize solar exposure.
3)System Size and Capacity: Based on your energy consumption and available roof space, determine the capacity of the solar system you require. Systems are typically measured in kilowatts (kW) or megawatts (MW). Opt for a system size that meets your energy needs without overcommitting. A general guideline is to install 1 kW of solar panels for every 100-120 Kwh consumption(monthly)
4)Quality of Solar Panels and Components: Invest in high-quality solar panels and components to ensure optimal performance and durability. Research reputable manufacturers and check for certifications to ensure the panels meet industry standards. Look for panels with a higher efficiency rating, as they can generate more electricity in the same amount of space.
5)Inverter Selection: Inverters convert the direct current (DC) generated by solar panels into usable alternating current (AC). Choose an inverter that suits your system size and type, such as string inverters, microinverters, or power optimizers. Opt for advanced inverters with features like remote monitoring to keep track of your system’s performance.
6)Government Policies and Incentives: Stay updated on government policies, subsidies, and incentives for solar installations. In India, various state and central government schemes offer financial support and tax benefits to promote solar adoption. For residential installations, look into subsidies that can significantly reduce your upfront costs. Commercial installations can benefit from accelerated depreciation, which provides tax advantages over time.
7)Budget and Financial Analysis: Calculate the total cost of the solar system, including installation, equipment, and maintenance. Compare this cost with potential savings over the system’s lifespan to determine your return on investment (ROI). Consider financing options like solar loans or power purchase agreements (PPAs) to make the investment more manageable.
8)Maintenance and Warranties: Understand the maintenance requirements of the solar system and inquire about warranties for panels and inverters. A well-maintained system can ensure consistent performance and longevity. Regular cleaning and occasional inspections are common practices to keep your solar panels operating efficiently.
9)Net Metering and Grid Connectivity: Familiarize yourself with net metering policies in your area. Net metering allows you to sell excess solar power back to the grid, potentially earning you credits on your electricity bill. Check your sanction load on your electricity bill. Generally maximum capacity you can install is capped at your sanction load. In that case you have to increase your sanction load first.
10)Professional Installation and Local Regulations: Choose a reputable and experienced solar installation company. Verify their credentials, previous work, and customer reviews. Consider old EPC company rather than any new one. Additionally, be aware of local building codes and regulations that may impact your installation. Professional installers follow safety guidelines and ensure compliance with local regulations during the installation process.
Conclusion: Investing in a solar rooftop system in India can bring long-term benefits, including reduced electricity bills and a lower carbon footprint. However, thorough research and careful consideration of the factors mentioned above, along with implementing general practices, are essential to make an informed decision that aligns with your energy needs, budget, and environmental goals. By taking these factors into account, you can maximize the benefits of solar energy while contributing to a sustainable future.
