Find a range of Off-grid rooftop solar panel systems in various capacities, with available brands like UTL, VIKARAM, and WAAREE that are designed to reduce electricity bills provide backup and contribute to environmental sustainability. It is a self-sustaining power plant that generates and stores its own electricity without any connection to the local utility grid. These systems typically include high-efficiency solar panels, high-efficiency batteries, a mounting structure, and all necessary wiring and safety components.
Key Features and Benefits
- Durability: Panels are rigorously tested to withstand heavy snow and wind loads, ensuring long-lasting performance with minimal maintenance.
- Warranty: 25-year performance warranty on solar panels and a 10-year warranty on the inverters, batteries and the overall system.Â
System Components
Off-grid solar systems include the following components:
Solar Panels: Non-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.
DC capacity off-grid inverter: The system includes an off-grid inverter that converts the DC power generated by the panels into AC power for household use. Inverters typically have a 10-year warranty.
Lead-acid battery: High-quality lead-acid batteries with a 10-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.
Loan Facility
Buyers can also avail loan facility from their concerned bank, with loan repayment schedules for various capacities of rooftop solar plants, ranging from 2 kW to 10 kW. The calculations are presented with an interest rate of 6% to 9% per annum for off-grid rooftop solar installations.
