Investing in solar energy is not just an eco-friendly choice—it’s a strategic decision that offers long-term financial and operational benefits for both residential and commercial users. However, despite solar’s growing popularity, many buyers still approach it as a simple plug-and-play solution, only to discover costly mistakes after installation.
At Innovel Energy, with over two decades of on-ground experience and 200,000+ installations across India, we’ve seen the solar journey from every angle. If you’re considering solar—especially in today’s dynamic energy landscape—here are the five most common mistakes buyers make, and how to make sure you’re not one of them.
1. Mistaking the Lowest Quote for the Best Deal
The mistake: In an effort to reduce upfront investment, many buyers are lured by the lowest quotation—often without understanding what’s being compromised. It could mean poor-quality panels, substandard inverters, untrained installers, or limited warranty coverage.
Why it matters: A poorly designed or low-quality system may underperform, degrade faster, or result in additional costs for repair and replacement—wiping out any savings in the long run.
The solution: Look beyond price. Evaluate system components, warranties, certifications, after-sales support, and most importantly, the track record of the installer. A Tier-1 panel with a 25-year performance warranty and a robust inverter from a reputable brand is non-negotiable.
2. Skipping a Detailed Energy Audit
The mistake: Some buyers go straight to installation based on rough estimates, without accurately assessing current and future energy consumption.
Why it matters: An undersized system won’t meet your needs, leading to dependence on the grid. An oversized one could be a financial deadweight if the extra power isn’t used or compensated properly.
The solution: A detailed energy audit is essential. At Innovel, we assess your historical electricity usage, peak load trends, future expansion plans (EVs, HVAC systems, machinery), and local DISCOM policies before recommending a system design.
3. Overlooking Site Conditions and Structural Health
The mistake: Assuming that every rooftop or ground space is solar-ready can backfire. Shading from nearby trees, improper tilt angles, weak rooftops, or water accumulation zones can all compromise system performance.
Why it matters: Even a small shadow on a solar array can reduce its output significantly. And structural issues could lead to long-term risks, including water leakage or system failure.
The solution: A site feasibility study is a must. We evaluate roof condition, load-bearing capacity, orientation, and shade mapping through tools like solar pathfinders and drone surveys to ensure optimal layout and design.
4. Not Leveraging Incentives, Net Metering & Policy Benefits
The mistake: Many consumers are unaware of available government subsidies, accelerated depreciation (for businesses), and net metering regulations—missing out on major financial advantages.
Why it matters: Navigating the bureaucracy alone can be daunting, especially with varying state-wise DISCOM norms. Missing these opportunities directly impacts your payback period.
The solution: Choose an experienced solar partner who can handle end-to-end documentation—from net metering applications to availing benefits under schemes like PM Surya Ghar: Muft Bijli Yojana. Innovel’s in-house compliance team ensures zero delays and complete transparency.
5. Choosing the Wrong Installer or an Inflexible EPC Model
The mistake: Many buyers treat solar installation as a one-time project and fail to assess the installer’s long-term commitment or capabilities in providing operations & maintenance (O&M) support.
Why it matters: Solar is a 25-year asset. Installation quality, after-sales service, and system monitoring are as important as the hardware itself. A good EPC provider is one that stays accountable after the panels are installed.
The solution: Work with a solar partner who offers flexible business models (CAPEX, OPEX, RESCO) and comprehensive AMC/O&M support. At Innovel, we offer everything from system health tracking to performance analytics—so your asset keeps delivering optimal returns.
