Raising Standards for Solar Installers

When I started working on Indian solar projects after spending a few years in the Australian solar industry, I was honestly surprised by what I saw, especially in how earthing is done. Later, when I started working on solar projects in the USA, I realized something clearly: The concept of earthing is completely misunderstood. In India, I noticed some common practices mentioned below that don’t follow international standards and more importantly, can be unsafe: 1. Separate earth electrodes for each item—transformer neutral, transformer body, inverters, lightning protection, and more—but no proper bonding between them. 2. AC and DC systems have their own separate earthing, and they’re not connected—no one could tell me which standard says to do that. 3. Installers proudly say things like “We’ve installed 10 earth pits!”—as if more pits mean more safety. 3. Inspectors ask “How many earth electrodes are there?” instead of checking if the system is safe and well-bonded. 4. Even in interviews, I was expected to say: “Two earth pits for LPS, two for structure, two for DC, two for AC—and they must be kept separate.” If I said otherwise, it seemed like a wrong answer. But this is not how it should be. These ideas are not in any standard but have become a common practice over time. In CEA regulation published in 2023 clearly states that "earthing means connection of the exposed conductive and extraneous parts of an installation to the main earthing terminal of that installation or connection of neutral of transformer or generator or equipment to general mass of earth or earth bonded bar of that installation". So earthing system should be like -One common, well-connected earthing system -Everything—DC, AC, LPS, inverters—all bonded together -Focus on safety, fault handling, and transient protection, not just the number of pits in the ground Standards like IEC 60364, IEC 62548, IS 3043, and IEEE 80 are very clear: Having multiple separate earths without bonding is unsafe. It can create dangerous voltage differences during lightning or faults, which can harm people and damage equipment. Let’s be honest—what we often call “standard practice” in India is actually just a misconception passed down for years. It’s time we question it. 💡 Let’s move beyond the habit of counting earth pits. Instead, let’s ask: 👉 Is the system bonded? Is it safe? Does it follow proper standards? Special Note: During inspections, if an electrical inspector asks for separate earth pits for LPS, DC, AC, structure, etc., we must respectfully ask: "Can you please tell me which standard recommends this?" #SolarPV #EarthingSystem #ElectricalSafety #IS3043 #IEC60364 #NEC #IEEE80 #SolarIndia #AustraliaToIndiaToUSA #SolarDesign #PowerSystemSafety #AarvigenEnergy

Why You Shouldn’t Use Cheap Mounting Structures for Solar Panels 1. Structural Integrity Matters Cheap mounting structures may save money upfront but often lack the strength and durability to withstand harsh environmental conditions like high winds, heavy rain, or extreme temperatures. A poorly constructed structure could lead to catastrophic system failure, damaging expensive solar panels and increasing overall costs. 2. Compromised Safety A solar installation is not just a project; it’s a construction site. Cutting corners on the mounting structure can pose serious safety hazards during installation and throughout its lifespan. Structural failures could harm workers or surrounding property. 3. Long-Term Financial Losses Investing in quality mounting structures ensures the solar system’s efficiency and longevity. Cheap structures may corrode or deteriorate quickly, requiring expensive repairs or replacements that negate the initial cost savings. 4. Regulatory Compliance Construction sites must comply with building codes and regulations. Low-quality mounting structures might not meet these standards, leading to fines, legal issues, or the need to redo the installation. 5. Impact on Solar Performance A stable and precise mounting structure ensures proper panel alignment and tilt, which is critical for maximizing energy output. Cheap structures often fail to maintain the required precision, reducing the system’s overall performance. 6. Reputation and Trust For installers and companies, using substandard materials can harm reputation and customer trust. Treating the site as a proper construction project and using high-quality mounting structures demonstrates professionalism and long-term commitment. Treating Solar Installations Like a Construction Site • Site Assessment: Properly survey and prepare the site, just as you would for any structural construction project. • Engineering Standards: Use structures designed and certified to handle local wind, seismic, and load conditions. • Quality Assurance: Choose materials that resist corrosion, UV damage, and weathering for extended performance. • Safety Measures: Equip the site with necessary safety precautions like secure scaffolding, PPE, and detailed installation plans. By treating solar mounting structures as a critical part of a construction site, you ensure the installation’s safety, efficiency, and long-term success. Skimping on this foundation undermines the entire investment.

Most training centres would cancel a training session with just one student. - 𝙒𝙚 𝙙𝙞𝙙𝙣’𝙩. This month, our solar installation training ran with one student - with the same standards and structure we run for a full class. This is a first. One person sat through the full program and completed the entire duration. That wasn’t a mistake. 𝙋𝙚𝙤𝙥𝙡𝙚 𝙖𝙧𝙚 𝙞𝙣𝙛𝙧𝙖𝙨𝙩𝙧𝙪𝙘𝙩𝙪𝙧𝙚. (I covered this in detail during my featured interview with pv magazine Global - https://lnkd.in/e6r4V32M) And over time, I’ve learned that training people isn’t about filling rooms. It’s about intentionality, focus, and attention. It’s also about 𝙥𝙧𝙤𝙩𝙚𝙘𝙩𝙞𝙣𝙜 𝙨𝙩𝙖𝙣𝙙𝙖𝙧𝙙𝙨; especially in work that involves rooftops, electricity, and real risk. At the Renewable Energy Technology Training Institute (RETTI), we invest deeply in each student: the quality of knowledge shared, the calibre of instructors (our strongest feedback on Google), the attention during training, and the time, money, and energy spent after training through our Growth Support Plan to ensure real competence. Because of this, I pay close attention to seriousness before accepting anyone. I’ve seen what happens when unprepared people are rushed into the field. Systems fail. Safety is compromised. Trust is lost. 𝙎𝙤 𝙮𝙚𝙨, 𝙄’𝙫𝙚 𝙗𝙚𝙘𝙤𝙢𝙚 𝙘𝙝𝙤𝙤𝙨𝙮. Not because demand is low, but because the cost of lowering the bar is high. This month, the person who showed up was aligned with the work. 📌He trained alone. 📌Climbed rooftops. 📌Handled panels with care. 📌Repeated installations until they were clean. 📌Asked thoughtful questions. 📌Finished strong. I am proud of him! One focused trainee, fully immersed, is better than a full room of people who are only half-committed. We do not accept students when I notice things like: ✔️You want a certificate but show little interest in competence ✔️You’re unserious about the tedious process required to master this work ✔️You show up late to learn a skill that demands discipline and safety Some people call this “too choosy.” I call it responsibility. The truth is simple: We don’t train everyone. We train the right people. If this way of learning resonates with you, you’ll find your way to us.

🚨 "Bhai, inverter kharab hai!"  No. The installation is. In the past 1–2 years, it seems everyone is in the solar business. Electricians, plumbers — even drivers — have become "solar technicians." But ask yourself:  🛠 Is it really that simple to handle a hybrid system worth millions?  Or are we playing with people's investments — and their safety? As part of the aftersales team, my engineers and I deal with this daily:  ❌ PV + and – reversed  ❌ Grid connected to the backup port  ❌ Load wired into the input terminal  ❌ MPPTs shorted, AC sides blown  ❌ Inverters blamed for installer mistakes And the irony?  “Sir, 100+ systems install kiye hain.”  Yes — 100+ bad jobs, done proudly. No understanding of DC, AC, settings, protections — yet full confidence. 💸 And here’s what’s enabling this…  “EPC companies are too expensive.”  “I’ll just buy my own inverter, panels, and structure.”  “I’ll hire a road-side electrician to install it.”  “Look, I saved Rs. 50,000!” But wait… Did you really save? When something goes wrong — who takes responsibility? Not the seller.  Not the road-side installer.  Not the warranty department.  Just you. ⚠ You're risking your home. Your family. Your investment. And for what? 🌞 It’s time we educate the market. Solar is not plug-and-play. It’s not about just making the inverter turn on. It’s about:  ✅ Proper design  ✅ Safe installation  ✅ Smart configuration  ✅ Long-term performance And that requires trained professionals, not shortcuts. 📣 Let’s raise awareness.  📣 Let’s protect the customers. 📣 Let’s protect the solar industry. #SolarPakistan #AftersalesTruth #SolarInstallers #InverterFail #SolarEducation #RayabEnterprises #HybridSystem #CleanEnergy #CustomerAwareness
