Thinking of harnessing India’s abundant sunshine? This guide explains the rooftop solar installation process from booking and site survey to net-metering approvals. Updated with 2025 subsidy figures and typical costs, it also covers solar site-survey checklists and mounting-structure types so you can make informed decisions.
Delhi NCR’s scorching summers, winter haze and heavy dust mean solar performance can vary a lot by season. Delhi sees average highs near 38–40 °C in summer (even above 45 °C in heatwaves), and frequent fog or smog in winter. Studies show Delhi’s pollution cuts panel output ~12–17% in haze. NASA-based data (Delhi: lat 28.7° N) finds typical rooftop PV yields ~5.7 kWh/kW-day in summer, ~3.7 in winter, with an ideal fixed tilt around 26°. Dust storms and monsoon rains also block sun. These local factors make equipment choice critical: high heat or dirt can throttle cheap systems, so ignore brand hype and focus on the actual numbers.
For people with families living in independent houses or top-floor residences in Delhi, electricity bills often account for a major part of monthly household expenses. In 2025, understanding how your electricity bill is structured and how to reduce it is crucial if you're managing a home.
Let’s break down the key components of your electricity bill and explore smart ways to reduce it, especially through solar energy and subsidy optimization.
