Process for Installing Solar System in Tamil Nadu
Below is a systematic guide to a successful rooftop solar installation:
Step 1: Consult with rooftop solar installers: Before purchasing solar systems or components, consumers should ensure that the quality and standards align with those set by the Ministry of New and Renewable Energy (MNRE). Refer to the Help Documents available on the National Portal for Rooftop Solar in the Simplification Procedure section.
Step 2: Site visit by solar installers: Solar installers conduct site visits to understand and calculate the necessary capacity and assess the available shade-free rooftop area for installation. Additional requirements for the rooftop solar system are evaluated during these visits.
Step 3: Determining required capacity for installation: As per TEDA’s specifications, 1kW of solar energy installation necessitates approximately 12 square meters or 130 square feet of space. To optimize sunlight exposure, rooftop areas should be free of obstructions such as tall buildings or trees. Panels should be positioned at least 2 feet away from the parapet wall to allow for cleaning and servicing.
The solar plant’s capacity can be determined based on the premises’ electricity consumption over the past year, referencing information available on physical copies of electricity bills through TANGEDCO’s online consumer portal.
Step 4: Requesting quotations from various installers: It’s crucial to compare products and services offered by different installers to select the most suitable installation. Obtaining quotes from multiple solar installers ensures access to the most competitive solar panel prices in Tamil Nadu.
Step 5: Assessing technical feasibility of connection with TANGEDCO distribution network: Consumers planning to install a rooftop solar PV system should contact TANGEDCO to ascertain the process for connecting the system to the utility’s distribution network or grid. TANGEDCO representatives assess the technical viability of linking rooftop solar with the electric grid at the consumer’s location.
Step 6: Fulfilling additional requirements: During site visits, installers may suggest additional requirements such as wires and an extra base for the solar system. Consumers may need to allocate space for storing panels and other components between product delivery and final installation dates.
Step 7: Material procurement: Depending on the terms outlined by the installer in the estimate, consumers may be required to make an advance payment to commence the rooftop solar installation process. Installers must supply materials within the specified time frame after receiving the advance payment, contributing to the solar system price in Tamil Nadu.
Step 8: Installation of the plant: Installers complete the installation after delivering materials within the estimated time frame. Solar panels are positioned at an angle to capture optimal solar energy, with the angle varying based on the locale and other factors, typically ranging from 5 to 15 degrees.
What is net metering?
The net meter, coupled with your solar panels, functions to monitor and log the energy flow to and from the local grid while managing surplus solar electricity. Through net metering, households equipped with solar power can sell excess energy to the grid in exchange for solar credits. Depending on the system size chosen, surplus units may be generated during peak sunlight hours.
Conversely, insufficient sunlight may lead to a shortfall in solar electricity production. However, net-metered households can still access electricity from the grid as needed.
If imported energy surpasses exported energy, the consumer pays the utility based on the net meter reading, representing the disparity between imported and exported energy. Conversely, if exported energy exceeds imported energy, the utility compensates the consumer for the net exported energy. It’s essential to note that an additional fee is incurred for installing a net meter, separate from the 3kW solar panel price in Tamil Nadu or any other system size selected.
How to Apply for a Net Meter in Tamil Nadu?
Here are the steps to apply for a net meter in Tamil Nadu:
Step 1: Reach out to the Tamil Nadu Generation and Distribution Corporation (TANGEDCO) to acquire the net meter application form.
Step 2: Complete the form with details related to your RTS system and personal information, such as name, address, connection particulars, and solar system capacity.
Step 3: Include the necessary documents, such as a copy of your electricity bill, identification proof, address verification, and a letter from your solar installer specifying your solar system’s capacity.
Step 4: Submit the filled application form and documents, along with the processing fee, to the TANGEDCO office in your locality.
Step 5: TANGEDCO will assess your application and conduct an inspection of your premises to verify compliance with safety and technical standards.
Step 6: Upon approval, TANGEDCO will install the net meter, which monitors both the electricity generated by your system and fed into the grid, and the electricity consumed from the grid. You can then commence benefiting from net metering, earning credits for surplus electricity generated by your solar system. Over time, these savings offset your initial solar investment and future electricity expenses.
