Address popular misconceptions about installation costs, technical reliability, and solar panel lifespans in India. This post establishes authority and builds trust, encouraging more businesses to go solar.
Despite solar energy becoming one of India’s fastest-growing renewable sources, several misconceptions still prevent homeowners and businesses from making the switch confidently. From inflated assumptions about cost to doubts over reliability, these myths often overshadow the remarkable progress solar technology has made in the last decade.
At SilInfra, we believe informed decisions begin with facts. Let’s bust some of the biggest myths about solar energy in India.
Myth 1: Solar Installation is Too Expensive
Fact: Solar power is now one of the most affordable sources of electricity in India.
Over the past decade, the cost of solar panels has fallen by nearly 80%, thanks to advances in manufacturing and government incentives such as MNRE subsidies and accelerated depreciation benefits for commercial projects.
Think of solar as an investment with long-term returns — typical payback periods range between 3 to 5 years, after which owners enjoy free electricity for 20+ years.
Myth 2: Solar Panels Don’t Work in Cloudy Weather or Cooler Regions
Fact: Solar panels generate electricity from sunlight, not heat.
India’s climatic diversity actually benefits solar power generation. Even on cloudy days, high-quality panels convert diffused sunlight into usable energy. In fact, moderate climates often enhance system efficiency because extreme heat can reduce panel output slightly.
Myth 3: Solar Energy Systems Are Unreliable
Fact: Modern solar systems are built to last and perform consistently.
Leading studies show that solar panels have a failure rate of only 0.05%, which makes them one of the most reliable energy technologies available. Additionally, inverters and mounting structures are now designed with industrial-grade durability, supported by warranties of 10–12 years (inverters) and 25 years (panels).
Regular AMC (Annual Maintenance Contracts) ensures minimal downtimes and optimal yields — a small price for seamless power security.
Myth 4: Solar Panels Have a Short Life Span
Fact: Most panels last 25 to 30 years, maintaining about 80% efficiency even after two decades.
High-quality monocrystalline modules degrade only 0.5–0.8% per year, and most manufacturers guarantee a 90% output for the first 10 years. Panels require minimal maintenance — just occasional cleaning to remove dust and debris.
Myth 5: Solar Maintenance Is Complicated and Costly
Fact: Solar panels are almost self-sustaining.
They have no moving parts, which means minimal wear and tear. Cleaning the panels periodically and scheduling professional inspections once a year is sufficient to keep them performing efficiently. The annual maintenance cost typically amounts to just 1–2% of the system cost.
