Band A vs Other Tariff Bands: What a Village Workshop in Oyo State Should Know Before Going Solar

Picture this: you run a small welding and fabrication shop in a village near Igboora, Oyo State. No NEPA light for years. You've been managing with a generator, but fuel prices are killing you. You've heard people talk about Band A and other tariff bands and you're wondering if it matters to you. Let's talk.

What are these tariff bands sef?

The bands are how the electricity distribution companies (DisCos) group customers based on how many hours of light they get. Band A customers are supposed to get at least 20 hours daily, Band B 16 hours, and so on. The higher your band, the more you pay per unit. But if you're in a village with no grid at all, you're not on any band—you're simply off-grid. So why should you care?

Because the band system affects the bigger picture: the cost of grid power, how reliable it is, and how solar compares. Even if you're off-grid today, knowing the bands helps you plan for the future and understand why solar makes sense.

But we don't even have light. Why should I bother about bands?

Good question. Two reasons. First, the government keeps talking about extending the grid, and when it comes, you'll likely be assigned a band. If you're in a remote area, you'll probably be Band B or lower—meaning fewer hours and maybe lower tariff. But don't hold your breath. Second, the band system is a reminder that even grid-connected businesses pay heavily for unreliable power. Solar gives you control.

So how do I size a solar system for my workshop?

Start by listing your equipment and how long you use each daily. For a typical small workshop, you might have:

• Welding machine: 3,000W, used 2 hours/day → 6,000Wh
• Angle grinder: 800W, 1 hour/day → 800Wh
• Drill press: 500W, 1 hour/day → 500Wh
• Lighting (LED): 100W total, 5 hours/day → 500Wh
• Phone charging, radio: 50W, 5 hours/day → 250Wh

Total daily energy: about 8,050Wh (or 8.05kWh). But that's just the running watts. You must account for motor startup surges—welding machines and grinders can spike to 2-3 times their rated power for a few seconds. So your inverter must handle those surges. For this load, a 5kW inverter with at least 10kW surge capacity is wise. Battery bank: if you want one day of autonomy, you need at least 8kWh usable, so a 10kWh lithium battery (or lead-acid with depth-of-discharge factored) would do. Solar panels: to recharge that daily, you need about 2kW of panels in Oyo's sunshine (roughly 4-5 peak sun hours).

But this is just an example. Your actual needs depend on your tools. Use our free sizing tool at /powermatch to get a tailored estimate.

What's the difference between all-in-one solar generators and separate inverter + battery?

All-in-one units pack inverter, battery, charge controller, and BMS into one box. They're easier to install—fewer cables, simpler mounting—and often safer for beginners because the DC connections are internal. Separate components give you more flexibility to expand and replace parts individually, but they require more planning and professional wiring. For a workshop, if you want plug-and-play and less installation headache, an all-in-one solar generator in Nigeria is a solid choice. If you plan to scale up later, separate components might be better. Either way, ensure the inverter can handle your surge loads.

Can I start small and upgrade later?

Yes. Many workshops start with a system that covers lights, fans, and small tools, then add more panels and batteries as money comes. The key is to buy an inverter and charge controller that can handle future expansion. For example, if you start with a 3kW inverter but plan to add a welder later, you might want a 5kW unit now. Also, lithium batteries are modular—you can add more in parallel later. But check that your all-in-one unit allows expansion; some are sealed.

What about the Band A vs other bands—does it affect my solar decision?

Only indirectly. If you were on the grid, Band A would mean higher tariff but more hours; Band B lower tariff but fewer hours. For an off-grid workshop, you're your own DisCo. Your "tariff" is the cost of fuel and generator maintenance. Solar reduces that to zero after installation. So the band debate is a reminder: grid power isn't free, and reliability matters. Solar gives you both.

How do I handle maintenance and safety?

Solar panels need occasional cleaning—dust in Oyo's harmattan season can cut output by 10-20%. Batteries need to be kept in a cool, ventilated place. Inverters should be installed in a dry area. For installation, always use a qualified electrician—live DC work is dangerous. If you're using an all-in-one unit, mounting is simpler, but you still need proper fusing and earthing. Don't cut corners.

What common mistakes should I avoid?

• Underestimating surge loads: that welding machine might need 3x its rated power to start.
• Mixing battery types or ages: it reduces lifespan.
• Ignoring depth of discharge: lead-acid batteries shouldn't be drained below 50% regularly.
• Not planning for expansion: you'll likely need more power later.
• Buying cheap cables: they waste energy and can overheat.

Can I pay small small?

Yes, we offer instalments over 2-4 months at /paysmallsmall. It's a way to get your system without tying up all your capital at once.

Final word

Don't let the band talk confuse you. If you're off-grid, focus on your actual energy needs. List your tools, calculate daily watt-hours, account for surges, and size your system with a margin. Start with a reputable installer and quality components. And if you're ready to see options, check our products page at /products. No hype—just honest power for your workshop.
