Tata Power Solar is one such brand that consistently delivers.

Ekam Energy: Your Trusted Partner for Quality Solar

At Ekam Energy, we believe that the true value of a solar product lies in the reliability of the company behind it. While the government mandates a 10-year manufacturing warranty and a 25-year performance warranty for solar panels, this doesn’t mean all panels are created equal. We conduct thorough due diligence to ensure you get the best brands that honor their obligations for decades to come.

What is an On-Grid Solar System?

An on-grid (or grid-tied) solar system is directly connected to the public electricity grid. Here’s how it works:

1. Solar Power Generation: Solar panels convert sunlight into DC electricity.
   
    
2. Inverter Conversion: A grid-tied inverter converts this DC electricity into usable AC electricity for your home or business.
   
    
3. Consumption & Net Metering: This AC power is first used to power your premises. If your panels generate more electricity than you’re consuming, the excess is automatically fed back into the utility grid. Through a system called net metering, you earn credits for this excess power, effectively running your meter backward or reducing your future bills.
   
    
4. Grid as Backup: When your solar panels aren’t producing enough electricity (e.g., at night, on cloudy days), your premises seamlessly draw power from the grid.

Not All Solar Panels Are Created Equal: The Tata Power Solar Difference

It’s tempting to opt for the cheapest solar PV system, but as Ekam Energy always emphasizes, “The best deal is very rarely the cheapest deal.” A solar panel is a long-term investment, designed to last decades. Choosing a manufacturer like Tata Power Solar, which invests heavily in manufacturing quality and reputation, is critical for ensuring your system’s longevity and performance.

Beware of Cheap Systems:

• Inferior Components: Cheap systems often use low-quality panels and inverters.
  
   
• Micro Cracks and Cell Damage: Poor quality panels are prone to microscopic cracks and other cell damage, leading to rapid degradation in efficiency.
• Delamination: Substandard manufacturing processes or materials can cause delamination (the detachment of layers), allowing moisture and air to corrode the panel and cause premature failure.
  
   
• Fabricated Ratings: Some manufacturers misrepresent efficiency and power tolerance ratings, making their products appear better than they are.

Choosing the Right Solar Panels: Embracing Next-Generation Technologies

What truly determines your outcome in terms of system performance over the lifetime of the solar panel is a lack of defects in the manufacturing process and having a company that will replace the panels if their performance falls below the warranted levels. This is where choosing a good brand like Tata Power Solar, known for investing heavily in quality and reputation, becomes paramount.

The solar industry is rapidly advancing with new cell technologies that offer even higher efficiencies and innovative features. Tata Power Solar, being a pioneer, is at the forefront of adopting these advanced solutions and is a major manufacturer of these components in-house:

• TOPCon (Tunnel Oxide Passivated Contact) Solar Panels: This is an advanced evolution of N-type technology. TOPCon panels feature an ultra-thin layer of silicon dioxide (SiO2) that significantly reduces electron recombination losses, leading to much higher efficiencies (often exceeding 22-23%, with some reaching close to 29% in lab conditions).

• • Advantages of TOPCon:
    
    • Higher Efficiency: Generates more electricity from the same footprint, ideal for limited roof space.
    • Lower Degradation: N-type cells, like those used in TOPCon, generally experience less initial (LID – Light Induced Degradation) and long-term degradation compared to P-type (PERC) cells, ensuring better performance over 30+ years.
      
       
    • Better Low-Light Performance: Excels in cloudy conditions or early mornings/late evenings.
    • Improved Temperature Coefficient: Maintains higher performance in hot climates.
      
       
    • Enhanced Durability: Often built with robust materials for extended lifespan.
  • Consideration: TOPCon panels currently have a higher upfront cost, though this is justified by their superior long-term energy yield.
    
     

    Bifacial Solar Panels: Unlike traditional monofacial panels that capture sunlight only from the front, bifacial panels are designed with solar cells on both sides, allowing them to absorb light from both the front (direct sunlight) and the back (reflected light from surfaces like rooftops, ground, or snow).

     
    • Advantages of Bifacial:
      
      • Increased Energy Production: Can boost energy yield by 5% to 30% depending on the installation environment (e.g., highly reflective surfaces like white gravel or elevated structures).
      • Higher Lifetime Energy Yield: The dual-sided energy capture leads to greater overall energy generation over the system’s lifespan.
        
         
      • Enhanced Durability: Often built with a dual-glass design, making them more resistant to mechanical stress, micro-cracks, and environmental factors like humidity.
        
         
      • Aesthetic Appeal: The transparent design can look sleeker in certain architectural settings.
    • Consideration: Bifacial panels perform best when elevated or installed on light-colored, reflective surfaces to maximize backside capture. Their installation might require slightly different racking.
      
       
      Tata Power Solar’s commitment to manufacturing high-quality cells and modules in-house, including TOPCon and Bifacial variants, means they maintain stringent quality control across the entire production chain. This gives them unique oversight into the performance and reliability of their components.

Inverters: The Heart of Your Solar Energy System

While solar panels generate DC electricity, an inverter is indispensable as it converts this DC into usable AC electricity for your home or business. Given that your solar plant is expected to perform for 25 years, the inverter’s quality and reliability are paramount.

Why Inverter Choice Matters:

• Longevity: A high-quality inverter is crucial for the long-term health and performance of your entire system.
  
   

Prompt Service: Most inverter manufacturers require certified technicians for servicing. It is vital to choose a brand that has a robust service network in your local area. Ekam Energy ensures that chosen brands, like Tata Power Solar, have strong local support, minimizing downtime in case of any failures. This also includes understanding if any distributor is maintaining repairs for your solar inverter in a nearby location.

At Ekam Energy, we meticulously select and offer only the best brands and technologies to meet each customer’s specific requirements, ensuring your solar investment is sound and sustainable.

Safeguarding Your Investment: Direct Warranty and Insurance Options

One of the most compelling reasons to choose Tata Power Solar is their robust warranty system. Tata Power Solar provides direct warranties on its manufactured components, such as solar modules, which come with a 25-year performance warranty and a 10-year product warranty directly from Tata Power Solar, not just from the dealer. This ensures that the manufacturer, a large and stable entity, is directly responsible for honoring the warranty obligations. For other high-quality components within the system, Tata Power Solar stands behind the overall system’s integrity, ensuring that all components meet stringent quality standards and are backed by appropriate manufacturer warranties, providing you with immense peace of mind.

While product warranties cover manufacturing defects, your solar system is also an asset that can be vulnerable to external damage (e.g., natural calamities, theft, accidents). To protect your investment comprehensively, it’s highly recommended to consider solar insurance options. Several general insurance providers in India, including Tata AIG, offer specialized policies for solar rooftop systems. These policies typically cover:

• Fire and allied perils (lightning, explosion, storm, flood, etc.)
