Backup & Off-Grid Solar Design Made Easy: The Installer's Field Manual for Sizing, Quoting, and Earning from Inverter and Solar Systems

Backup & Off-Grid Solar Design Made Easy: The Installer's Field Manual for Sizing, Quoting, and Earning from Inverter and Solar Systems 🔥

Stop paying for darkness. Learn to design the system that ends it — for good.

If you live or run a business in Africa, you already know the maths by heart. Diesel near $12 a litre — and still no guarantee the light will stay on. A generator that groans all night and eats money it can never give back.

Here is what most people don't know: a correctly designed solar system now pays for itself in two to four years for a typical home, and three to five for most small businesses. Solar in Nigeria stopped being about going green. Today it is simply cheaper than the alternative. The problem was never the technology — it was knowing exactly what to buy, how big, and from whom.

That is what this book hands you.

Solar Backup & Off-Grid Design Made Easy is the complete, no-jargon field manual that professional installers use — now written so a homeowner or business owner can follow it from the first page. By the end, you will understand your own power needs better than most of the people trying to sell you a system. No one will be able to oversize you, undersize you, or overcharge you again.

This book is for you if you:

• Are tired of diesel costs and unreliable Band A power and want a permanent fix.
• Run a shop, clinic, salon, church, school, or office that loses money every time the grid fails.
• Want to buy or commission a solar/inverter system without being cheated by an unqualified installer.
• Want to design and even install your own system, step by step.
• Are an aspiring installer who wants to learn the trade properly and build a business from it.

What you'll be able to do after reading it:

• Calculate exactly how much power you need — no guesswork, no oversizing, no wasted naira.
• Choose the right inverter (hybrid, stand-alone, grid-tied, or power inverter) for your situation — and know why.
• Size your batteries correctly for the lithium era — most old advice is wrong, and this book corrects it.
• Specify your solar array and charge controller so the system actually performs.
• Install safely — solar involves high DC voltages that don't naturally stop arcing; the safety chapter could save a life.
• Work out your real payback and ROI so you know precisely when the system has paid for itself.
• Spot a bad quote or a dangerous installation before you hand over a penny.
•

Written by an authority you can trust

Engr. Abiodun Ojobaro is one of West Africa's foremost authorities on solar energy, with over a decade of hands-on design, installation, training and consulting across Nigeria and the region. He holds a BSc in Electrical & Electronic Engineering (University of Ibadan) and an MSc in Renewable & New Energy Systems (University of Nigeria, Nsukka). He is a COREN-registered engineer, a member of the Nigerian Society of Engineers, a certified energy-audit professional (CIET, Canada), and a certified trainer with the Renewables Academy (RENAC) Berlin and the Siemens Power Academy, Lagos.

In short: the person teaching you actually does this for a living, at the highest level — and has trained the people who install systems across the country.

The honest value

One oversized battery bank wastes more than the price of this book. One cheated or unsafe installation can cost you many times more — in money, in ruined equipment, or worse. For less than the cost of a few litres of diesel, you get the knowledge to make every naira you spend on power work for you, for years.
