A poorly designed or improperly installed solar power system is a long-term financial liability rather than an asset. India's rooftop and off-grid solar sector suffers an estimated Rs 4,800 crore annually through undersized systems delivering 30-40% less generation than promised, non-MNRE-empanelled installers creating DISCOM rejection at net metering application, faulty AC/DC wiring creating fire risk, and systems without proper earthing causing grid fault liability. Trade4Asia verifies MNRE empanelment, system design quality, component specifications (ALMM panels, approved inverters), installation workmanship, and post-installation support capability for every listed solar power system supplier.

FAQ's

What is the difference between on-grid, off-grid, and hybrid solar systems?

On-grid systems are connected to the electricity grid with no battery storage — they generate power when sunlight is available, export surplus to the grid (net metering credit), and draw from the grid at night or on cloudy days. Power fails during grid outages (safety shutdown). Off-grid systems are completely independent of the grid — battery storage provides power when the sun is not shining; sized for multi-day autonomy in remote locations. Hybrid systems combine grid connection with battery storage — they use solar first, store surplus in batteries, and use the grid only as a backup; they provide uninterrupted power during grid failures while maintaining grid connection benefits.

How much roof space is required for a 10 kWp solar system?

A 10 kWp solar system using 440 Wp mono PERC panels (23 panels) requires approximately 155-180 sq metres of shadow-free roof area (including panel spacing for maintenance access and structural clearances). As a practical rule: 15-18 sq metres of shadow-free roof per kWp of solar. South-facing roof is ideal; east or west-facing reduces generation by 15-20%; north-facing reduces generation by 30-40% and is generally not recommended for installation in India (north of the equator). For flat rooftops, panels are typically installed at 10-15 degree tilt to allow self-cleaning and maximise annual generation.

What is net metering and how does it work in India?

Net metering allows grid-connected solar system owners to export surplus solar generation to the DISCOM grid and receive credit at a specified rate (typically between Rs 2.50 and Rs 6.50 per unit, varying by state and consumer category). The bidirectional net meter measures both import (from grid) and export (to grid). Monthly electricity bill = (Units consumed from grid - Units exported to grid) x tariff. If export exceeds import in any billing period, credit is carried forward to the next bill. Most states allow systems up to 500 kWp for commercial and up to 1 MW for industrial consumers under net metering regulations.

What is PM-KUSUM scheme and what subsidy is available for farmers?

PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) has three components: Component A — installation of small solar power plants (500 kW to 2 MW) on barren/fallow farmland; Component B — installation of standalone solar pumps replacing diesel pumps; Component C — solarisation of existing grid-connected agricultural pumps. Under Component B and C, the farmer receives a 30% central government subsidy and typically 30-40% additional state government subsidy — resulting in farmer contribution of only 10-30% of total system cost. Applications are made through the state DISCOM or state nodal agency.

How long does the DISCOM net metering approval process take?

The DISCOM net metering application to approval timeline varies by state: in Gujarat, Maharashtra, and Karnataka (most progressive DISCOM net metering implementation), typical approval time is 30-60 days from technically complete application submission. In some states with manual processes, approval can take 90-180 days. Common rejection reasons: non-ALMM panels; non-BIS-certified inverter; incorrect load capacity (system kWp exceeding permitted % of sanctioned load); inadequate earthing documentation. MNRE-empanelled installers with established DISCOM relationships and experience with the specific DISCOM significantly reduce approval time and first-attempt rejection risk.
