Solar energy is a long-term investment. While local EPC players may offer tempting lower prices, the real question is: are you saving money, or will it cost you more over time?
Here are common customer questions answered to explain the difference between local EPC players and premium brands, along with financial and non-financial impacts.
A: Solar plants are low-maintenance because they have no moving parts, but this doesn’t mean they perform equally. The key metric is energy generation efficiency. A premium brand’s superior design, panels, and balance of systems (BOS) ensure up to 10-15% more energy generation over time.
Additionally, when faults occur:
- Premium brands respond quickly, often within 24-48 hours, and honor warranties.
- Local EPCs may delay service, charge extra, or blame the user for faults.
Financial Impact:
- For a 100 kWp plant, even a 10% efficiency gap can mean ₹1,00,000-1,50,000 loss annually due to lower generation.
- Delayed repairs can add another ₹20,000-30,000 per year in downtime costs.
Q2: What makes premium brands more expensive upfront?
Premium brands in the solar industry, are generally more expensive compared to local EPC players due to several key reasons:
Quality of Components:
Premium Brands use high-performance panels and Balance of System (BOS) components (inverters, cables, mounting structures) that offer superior energy production and longevity. These components come with certifications that ensure they meet international standards for efficiency, safety, and durability.
Professional Installation:
Premium brands typically use skilled and experienced technicians for installation. The proper installation ensures maximum energy output and minimizes operational issues. Local EPC players may employ less experienced labor, resulting in improper setup, reduced efficiency, and potential long-term issues.
Comprehensive Survey and Design:
Premium brands conduct thorough surveys and use advanced technology such as drones and 3D modeling software to design the system, ensuring optimal energy generation based on site-specific conditions. Local players may rely on basic surveys and design, leading to inefficiencies in the system.
After-Sales Service:
Reputable brands offer extended warranties (e.g., 25 years for panels) and dedicated after-sales support. This helps maintain system performance over its lifetime. Local EPC players may offer shorter warranty periods and less reliable after-sales service, resulting in more repairs and system downtime.
Safety and Security:
Premium Brands adhere to stringent safety standards, providing certified components and ensuring that the system operates without safety risks. Local players might not follow the same rigorous safety protocols, increasing the risk of electrical hazards or system malfunctions.
While these factors result in a higher initial cost, they ensure better long-term performance, reduced maintenance costs, and higher energy output over the system’s lifespan.
Q3: How do premium brands perform better in energy generation?
| Factor | Premium Brands (e.g., Tata) | Local EPC Players | Impact on Energy |
|---|---|---|---|
| Survey & Design | 5-10% higher efficiency | 3-5% less efficiency | Proper design optimizes sunlight capture, reducing losses. |
| Panel Quality | 95-98% efficiency over 25 years | 85-90% efficiency | Higher-grade panels generate 10-15% more energy annually. |
| BOS Quality | 5-10% performance boost | Frequent breakdowns | Durable BOS ensures uninterrupted energy transfer. |
| Installation Quality | 2-3% extra efficiency | 2-3% energy loss | Professional setup maximizes panel output. |
| Service | Quick, warranty-covered repairs | Delays, extra charges | Reduces downtime, ensuring consistent energy generation. |
| Safety | Certified, risk-free systems | Unsafe, uncertified | Avoids costly repairs and safety-related losses. |
Takeaway: Premium brands ensure 10-15% more energy generation annually, translating to significant financial savings.
Q5: Why is after-sales service so important?
A: Solar systems last 25 years, so issues are inevitable. Premium brands:
- Provide free or warranty-covered repairs.
- Offer timely on-site service, minimizing downtime.
Local EPC players often:
- Charge extra for repairs.
- Blame users for faults, increasing repair costs.
Financial Impact: A local EPC’s delayed service could cost ₹20,000-30,000 annually for a 100 Kwp system due to downtime.
Q6: Why does safety matter in solar systems?
A: Unsafe installations or uncertified components from local EPC players can lead to:
- Fires or electrical faults.
- Higher insurance premiums and repair costs.
Apart from electrical safety, other aspects of safety are equally crucial. For instance, if safety lines and walkways are not installed on a shed, it may lead to severe accidents such as a person falling while working on the shed. This could result in death or permanent disablement, causing:
- Substantial financial loss to the company.
- Legal disputes and compensation claims.
- Mental stress for the organization and individuals involved.
- The irreplaceable loss of a precious life.
Premium brands ensure:
- Certified, high-quality components.
- Compliance with stringent safety standards, including provisions for worker safety such as walkways and harnessing systems.
