Ask five different people what “permit” means for solar in Bangladesh and you’ll get five different answers. Some will mention SREDA. Others will talk about their DESCO or BREB office. A few will insist you need a building permit, the way you would for an extension or a new floor. The confusion isn’t really anyone’s […]

A solar plant that looks finished isn’t the same as a solar plant that’s ready to run. Between “installed” and “operational” sits commissioning — the stage where every connection, every protection system, and every test result gets checked before anyone signs the handover papers. Skip a step here, and the problems don’t show up on

Does Lightning Actually Damage Solar Panels? Bangladesh sits in one of the most lightning-active parts of the world, and the country has officially recognised lightning as a natural disaster after a string of high fatality years. So it’s a fair question for anyone with panels on their roof: is your solar system now a lightning

Why This Is the Part of a Solar Installation Nobody Checks Ask most people what makes a rooftop solar system safe, and they’ll talk about the panels, the inverter brand, maybe the warranty. Almost nobody asks about the earthing. That’s a problem, because earthing and bonding are the parts of a solar installation you can’t

Your solar panels don’t actually produce the kind of electricity your fridge, fan, or factory motor runs on. They produce DC — direct current, the same type a car battery stores. Everything in your home or office runs on AC, alternating current, the type that comes out of a wall socket. Somewhere between the roof

If you’re holding a torque wrench right now, here’s the number: most solar module clamps use M8 bolts torqued somewhere between 6 and 20 Nm, with 14-20 Nm being the range you’ll see most often across manufacturer manuals. That’s roughly 5-15 ft-lb if your wrench reads in imperial units. Now the part that actually matters.

Most people planning a solar project spend their energy comparing panel brands and inverter warranties. That makes sense — those are the parts you can point to. But talk to anyone who’s had to fix a solar installation after the fact, and the story is usually the same: the panels were fine. The structure underneath

Solar Project Timeline in Bangladesh: From Site Survey to Commissioning Most people assume the panels are the slow part. They’re not. Mounting a rooftop system on an average home takes an installer two to three days. What actually stretches a solar project out — sometimes by months — is everything around the panels: the survey,

If you’ve got open land instead of a good roof, ground-mounted solar isn’t a workaround — it’s often the better system. No shading from a neighbouring building, no worrying about roof age or load capacity, and a lot more flexibility in how the array is angled toward the sun. But it’s also a different installation

Most people who ask about rooftop solar installation aren’t ready to sign a contract yet. They just want to know what actually happens — how many steps there are, how long it takes, and what might go wrong along the way. That’s a fair thing to want to know before you let someone put panels
