The Photovoltaic Systems Handbook: A Practical Guide to Panel Selection, System Sizing, and Hands-On Exercises

Most people who get into solar energy learn by watching someone else install a system. They pick up habits, copy what they see, and hope the knowledge holds when a client's battery runs flat overnight, the inverter throws a fault code at 11 PM, or a site survey reveals a structural problem nobody anticipated. This book was written for the solar practitioner who wants more than that — who wants to understand what is actually happening inside the inverter, across the I-V curve of a solar panel, inside a battery cell during a charge cycle, and through every wire and fuse of a correctly designed system, so that no component, no fault, and no installation is ever a mystery.

Whether you are a homeowner planning your first solar system, a technician building a career in the fastest-growing energy sector on the planet, an engineer who wants to close the gap between theory and real-world installation, or an entrepreneur ready to build a solar business from the ground up — this is the book that earns a permanent place on your workbench.

• Understand the physics of solar radiation — spectrum, photon behaviour, peak sun hours, and irradiance maps — and apply those fundamentals directly to real system design decisions
• Trace energy from sunlight through solar cells, panels, strings, and arrays — then through inverters, batteries, and charge controllers — to the loads that actually consume it
• Read and interpret a solar panel datasheet like a professional: Pmax, Voc, Isc, temperature coefficients, degradation rates, and NOCT — without guessing and without relying on marketing claims
• Select the right inverter architecture — string, microinverter, optimizer, or hybrid — for any installation, and size it correctly without oversizing, undersizing, or clipping avoidable generation
• Size and configure MPPT charge controllers: calculate input voltage limits, output current requirements, MPPT range compatibility, and cold-weather Voc safety margins
• Conduct a complete system sizing exercise from load audit to array specification, string configuration, and battery sizing — using both hand calculations and professional simulation tools like PVGIS, PVsyst, and SAM

BUILT FOR LEARNING AND REAL-WORLD USE

The technical content is grounded in current technology: LiFePO4 batteries, TOPCon and HJT panels, hybrid inverters, bifacial arrays, smart monitoring platforms, and modern grid code requirements — not a snapshot of technology from a decade ago.

• Bonus 1 — Quick-Reference Design Cheat Sheet
• Bonus 2 — Country-by-Country Solar Incentive Snapshot
• Bonus 3 — Recommended Tools, Software, and Resources
• Bonus 4 — Glossary of 100+ Photovoltaic Terms

Written for homeowners evaluating their first solar investment, solar technicians and installers building a professional practice, electrical engineers bridging theory and field application, solar entrepreneurs identifying and building business opportunities, and anyone who wants a structured, complete, globally relevant understanding of photovoltaic systems — from the physics of the photovoltaic effect through to the economics of a 25-year solar investment.

Understand the resource. Size the system. Select the components. Install it correctly. Commission it safely. Monitor it intelligently. Build the business. Achieve energy independence.

Build the knowledge that keeps solar systems producing — and build the career and the business that come with it.
