Top Housing Societies Rooftop Solar Set

Find range of on-grid rooftop solar panel systems for for Group Housing Societies (GHS) and Resident Welfare Associations (RWAs), for common area facilities, in various capacities of various to brands; all designed to reduce electricity bills and contribute to environmental sustainability. These systems typically include high-efficiency solar panels, and grid connected inverter, a mounting structure, and all necessary wiring and safety components.

• Subsidy Amount: ₹18,000 per kW.
• Maximum Capacity: Up to 500 kW for common facilities (including EV charging).
• Max Potential Subsidy: A single society can receive up to ₹90 lakhs in total subsidy.
• Payback Period: With the subsidy, most societies recover their initial investment within 2–4 years.

Key Features

1. Net Metering: Excess electricity generated is exported to the grid, and you only pay for the net consumption, which can significantly reduce or eliminate monthly electricity bills.
2. Durability: Panels are rigorously tested to withstand heavy snow and wind loads, ensuring long-lasting performance with minimal maintenance.
3. Warranty: 25-year performance warranty on solar panels and a 5-year warranty on the inverters and the overall system. 

System Components

On-grid solar system includes the following components:

Solar Panels: DCR, High-efficiency monocrystalline panels, often around 540Wp (watts-peak) per panel. They come with a 25-year performance warranty and are designed for durability in harsh conditions.

Grid Connected Inverter: The system includes a grid-tied inverter that converts the DC power generated by the panels into AC power for household use and the grid. Inverters typically have a 5-year warranty.

Mounting Structure: A galvanized iron (GI) or aluminum mounting structure is provided to securely hold the panels on the roof or ground, designed to be wind resistant.

Balance of System (BoS): This includes essential safety and connectivity components like:

i) DCDB & ACDB: DC and AC Distribution Boxes with surge protection devices (SPD) and MCBs.

ii) Cables and Connectors: High-quality, UV-resistant DC and AC cables and MC4 connectors.

iii) Earthing Kit & Lightning Arrestor: Important safety features for grounding the system and protecting it from lightning strikes.

iv) Bi-directional Meter: This net meter is installed by the local electricity board to track both the electricity consumed from the grid and the surplus power exported to it, enabling net metering benefits.

• Legal Status: Must be a legally registered society with a valid PAN Card.
• Components: Must use Indian-manufactured DCR (Domestic Content Requirement) solar panels.
• Metering: The installation must be used for common facilities and not directly for individual residential supply.
