At Eltron Energy, we’ve spent over a decade in the solar industry, and a troubling pattern keeps repeating itself: many households that initially opted for budget installations from inexperienced providers suffer from poor energy output, frequent system breakdowns, and expensive maintenance needs.

A comprehensive study conducted by the Council on Energy, Environment and Water (CEEW) in collaboration with PV Diagnostics found that 50% of rooftop solar systems across Indian homes were underperforming, delivering 30% less energy than expected.

What does this mean for homeowners?

Imagine a family that invests in a solar system with high hopes of saving on their electricity bill, only to find out that their system generates 30–40% less power than promised. The impact? Frustration, reduced savings, and a delayed return on investment.

Why does this happen?

• Lack of awareness: Since solar adoption is still relatively new, most customers are first-time buyers unfamiliar with technical parameters.

• Price over quality: Many homeowners focus primarily on upfront costs rather than long-term savings, opting for cheaper setups with subpar components and installation practices.

• Non-accountable service: When problems arise, there is often no proper support system or warranty service from local, untrained installers.

Root Causes of Underperforming Solar Systems:

1. Dust & Bird Droppings
   Found in 80% of homes surveyed. Regular deep cleaning is often neglected, leading to reduced panel efficiency.

2. Shadowing Issues
   Affects 50% of systems due to improper shadow analysis. Even brief daily shade can drop overall performance and pose safety risks.

3. Cracked Solar Panels
   Found in 30% of systems due to temperature-induced stress, improper handling, or poor-quality modules.

4. Scaling & Hard Water Stains
   Affects 15% of installations. Using untreated water for cleaning can leave deposits that cause long-term performance loss.

5. Damaged Cables
   Present in 12% of surveyed homes. Poor cable management or wear-and-tear leads to high resistance and even electrical hazards.

6. Faulty Inverters
   10% of homes reported inverter breakdowns. These lead to total system shutdown, usually due to component failures or poor installation.

7. Microcracks & Snail Trails
   These subtle but serious defects result from moisture ingress or internal stress, affecting the module’s long-term output.

8. Uneven Orientation
   Affects 5% of homes. Incorrectly aligned panels severely compromise energy production due to poor installation standards.

Even worse, when homeowners try to claim warranties, they often face rejections due to the amateur nature of the installation work, which voids terms set by original equipment manufacturers.
