Training built on real incidents

Short courses for the people who own, run, insure, lend against or regulate energy assets. Every lesson is written from entries on the register, each linking to its sources, and ends with questions. Each course ends with a certificate that anyone can check. Lesson 1 of every course is free with a free account. The rest of each course comes with the 7-day free trial and the plans.

What the certificate is. A certificate is issued when every lesson's questions are passed at 75 percent or more. It carries the course title, the study hours, the learning outcomes and a check code. Anyone can check the code on the certificate page. Each certificate is also an Open Badge that can be verified against this site, and can be added to a LinkedIn profile in one click.

The study hours may be recorded as self-directed continuing professional development under your professional body's rules. The register does not hold a formal CPD accreditation. The syllabus, outcomes and assessment method for every course are published below so a professional body or employer can judge the material as it stands.

Battery storage fires: the essentials

4 lessons · about 1.5 hours of study · questions on every lesson, pass mark 75 percent · certificate with a check code

Solar PV fires: where they start

3 lessons · about 1.5 hours of study · questions on every lesson, pass mark 75 percent · certificate with a check code · version 1.0, written 5 November 2026, next review 5 May 2027

To give anyone who owns, operates, insures, lends against or regulates a solar PV system a clear, evidence-based understanding of where solar fires start, why rooftop fires are hard to fight, how ground-mounted sites are hit by vegetation fires and weather, and what controls the incident record supports.

Who it is for. Asset owners and asset managers, O&M firms and their site crews, underwriters, brokers and risk engineers, lenders and technical advisers, planning officers and fire service liaison staff. No electrical qualification is needed. Before you start. None. The battery storage course is not required. Readers new to solar PV will find every technical term explained the first time it is used.

By the end of the course you will be able to

  1. Explain why a DC fault can sustain an arc, and name the components and installation faults most often at the origin of a solar fire.
  2. Explain why a rooftop array stays live in daylight, how an array fire spreads into a building, and what to give the fire service before an incident.
  3. Set out the vegetation, firebreak and isolation controls for a ground-mounted site, and assess its exposure to hail, wind and water.
  4. Judge how far a reported cause can be trusted, and apply the register's evidence to your own sites.

Lessons

  1. Where solar fires start: connectors, isolators, inverters and the DC side (about 18 minutes)
    • Explain why a fault on the DC side of a solar system can sustain an arc and start a fire, when the same fault on the AC side usually would not.
    • Name the components that most often sit at the origin of a solar fire in the register, and the installation faults behind them.
    • Describe the checks at commissioning and in service that find these faults before they burn.
    • Judge how far a reported cause can be trusted, and what to ask for before acting on it.
  2. Rooftop systems: why roof fires are hard to fight, and what owners can do (about 18 minutes)
    • Explain why a rooftop array stays live in daylight and what that means for the people fighting the fire.
    • Describe how a fire in an array spreads into the roof and the building, and the design features that stopped it in the register's cases.
    • List what a building owner must give the fire service before an incident, and what good practice looks like on occupied buildings such as schools and hospitals.
    • Set out the controls for the three riskiest moments in a rooftop system's life: construction, roof work and the years after installation.
  3. Ground-mounted sites: grass, wildfire, weather and the people on site (about 18 minutes)
    • Explain how an electrical fault at a solar farm becomes a landscape fire, and the vegetation and firebreak controls the record supports.
    • Describe how a wildfire approaching a site is kept out, and what to inspect before re-energising afterwards.
    • Assess a site's exposure to hail, wind and water, including floating arrays, against the register's cases and the module standards.
    • Set out the arrangements for people on a solar site: isolation and proving dead, fire service liaison, and emergency response at remote sites.

Assessment. Each lesson ends with five questions. Each question tests one of the lesson's learning outcomes. The pass mark is 75 percent (four of five). You can retake the questions as often as you need. The certificate is issued when all three lessons are passed, and it carries the course title, the study time, the learning outcomes and a check code anyone can verify on the register.

How this course was made

Every lesson was written from entries published on the Energy Incident Register, each of which is written from named public sources and reviewed before publication under the register's methodology. Every incident named in a lesson links to its entry, where the sources are listed. Where a cause is alleged, disputed or not established, the lesson says so. The register's editor is responsible for the content. Standards are cited by name so readers can check the current edition that applies in their country.

By the end of the course you will be able to

  1. Describe the failure modes of lead-acid and lithium-ion UPS batteries.
  2. Set the controls needed for maintenance, switchover and testing work.
  3. Assess battery room separation, suppression and water supply.
  4. Check that failover does not depend on the building that has failed.

Lessons

  1. What sits in a UPS battery room, and how it fails (about 12 minutes)
  2. Maintenance, testing and works: the riskiest hours (about 13 minutes)
  3. When the battery room burns: separation, suppression and keeping the service up (about 14 minutes)

Being written, one at a time

  • Reading an incident report How to read a register entry with care: what a source can and cannot tell you, the difference between a stated cause and a finding, and how to spot patterns across entries.
  • Learning from energy asset incidents A twelve week course, one lesson a week, across battery storage, solar, wind, grid equipment and data centre power. Each lesson takes real incidents from the register and turns them into checks you can use on your own sites.
  • Incident risk for insurers and lenders A ten week course on using incident evidence in underwriting and due diligence. It covers loss patterns, design and product risk, business interruption, environmental liability and data centre exposure.
  • Battery and solar sites in planning: safety questions for councils A ten week course for councils deciding on battery storage and solar applications. It explains the risks in plain terms, how the NFCC guidance is used, and which questions and conditions are backed by real incidents.

Questions

Who writes the courses?

The register's editor, from the register's published entries. Every incident named in a lesson links to its entry, where the sources are listed. Where a cause is alleged, disputed or not established, the lesson says so.

How long does a course take?

Short courses take one to two hours and can be finished in a week. Every lesson states its reading time. Questions take about ten minutes a lesson.

Is the training CPD accredited?

No. The hours may be logged as self-directed CPD under your own professional body's rules, and the certificate states the hours and outcomes for that purpose. Formal accreditation is a possible later step; the material is published in full here so it can be assessed as it stands.

Can my team take a course?

Yes. A Team plan gives every seat the courses and the monthly crew briefing, and each person earns their own certificate. See the plans.

I run site crews. Is there something shorter?

Members receive a one-page crew safety briefing every month, built from recent incidents and written to be read out in a ten-minute toolbox talk.
