What Our Customer Says
FAQ's
-
What are bifacial solar panels and how do they work?Bifacial solar panels capture sunlight from both sides, increasing energy production by up to 30% compared to traditional panels. SLR Surabhi Power's bifacial modules use advanced glass-on-glass design with high-transmission tempered glass on both front and rear, allowing reflected light from the ground to generate additional power. Ideal for ground-mounted installations in sunny regions like Rajasthan.
-
What is TOPCon solar technology and its benefits?TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type solar cell technology that offers higher efficiency (up to 22.84%) and better performance in hot climates. SLR Surabhi Power's TOPCon panels feature zero LID, excellent PID resistance, and lower temperature coefficients (-0.30%/°C), making them superior to PERC for long-term reliability and higher yields in Indian conditions.
-
What is the efficiency of SLR Surabhi Power bifacial solar panels?Our TOPCon bifacial panels achieve up to 22.84% module efficiency, while PERC models reach 21.68%. This high efficiency translates to more power per square meter, reducing installation space requirements for large-scale projects. Perfect for maximizing ROI in utility-scale solar farms.
-
What power output range do your solar panels offer?SLR Surabhi Power provides bifacial panels from 530W to 590W. PERC models: 530-560W; TOPCon: 570-590W. All with positive power tolerance (0~+5W) for consistent performance in utility-scale and ground-mount applications.
-
What is the warranty on SLR Surabhi Power solar panels?We offer a 12-year product workmanship warranty and 30-year linear power warranty. TOPCon: 1% first-year degradation, 0.40% annual; PERC: 2% first-year, 0.45% annual. Ensuring 84-87% power output after 30 years for peace of mind.
-
Are SLR Surabhi Power panels ALMM approved?Yes, all our bifacial M10 modules are ALMM (Approved List of Models and Manufacturers) approved, making them eligible for government subsidies and DCR (Domestic Content Requirement) projects in India. Essential for MNRE projects and solar EPC contracts.
-
How do these panels perform in low light conditions?SLR Surabhi Power panels excel in low light, generating power during early mornings, sunsets, and cloudy days. TOPCon technology provides superior weak light response, ideal for India's variable weather patterns and monsoon seasons.
-
What is the bifaciality factor of your solar panels?Our PERC bifacial panels have up to 70% bifaciality, while TOPCon models reach 80%. This means they can produce 70-80% of front-side power from the rear, boosting overall yield in reflective environments like white gravel or TPO roofs.
-
What are the dimensions and weight of the panels?Standard size: 2278 × 1134 × 30 mm, weight 32.5 kg. Compact M10 144 half-cut cell design with 30mm anodized aluminum frame for easy handling and installation in large solar farms. Compatible with standard mounting systems.
-
What temperature coefficients do your panels have?TOPCon: Pmax -0.30%/°C, Voc -0.24%/°C, Isc 0.04%/°C. PERC: Pmax -0.32%/°C, Voc -0.25%/°C, Isc 0.06%/°C. Lower coefficients ensure stable performance in India's hot climates, minimizing power loss during peak summer temperatures.
-
What certifications do SLR Surabhi Power panels hold?ISO 9001:2015 (Quality), ISO 14001:2015 (Environment), ISO 45001:2018 (Health & Safety). Factory audited with comprehensive system certifications for reliable, eco-friendly manufacturing. Meets international standards for solar module production.
-
How many panels fit in a container?36 modules per box, 720 per 40' HC container. Efficient packing configuration optimizes shipping costs for large-scale solar projects across India. Reduces logistics expenses for EPC contractors and solar developers.
-
What mechanical loads can these panels withstand?Up to 5400 Pa snow load and 2400 Pa wind load. Designed for harsh weather: hail-resistant, hotspot-free, and micro-crack resistant for durability in extreme conditions. Perfect for high-wind areas like coastal Tamil Nadu and snowy Himalayan regions.
-
What's the difference between PERC and TOPCon solar panels?PERC (Passivated Emitter Rear Cell) offers good efficiency (up to 21.68%) with Ga-doped cells. TOPCon provides higher efficiency (22.84%), zero LID, better hot climate performance, and 16 busbars for reduced micro-cracks. TOPCon is ideal for premium, long-term installations.
-
Are these panels suitable for utility-scale projects?Yes, SLR Surabhi Power bifacial panels are optimized for large-scale utility and ground-mount projects. With M10 cells, smart soldering, and robust design, they deliver high yields and reliability for solar farms in Rajasthan and beyond.
