Solar PV installer
An 8-step path to installing rooftop solar: DC electrical and roof safety, site surveys and system sizing, mounting rails and panels, string wiring and grid-tied inverters, battery storage, app monitoring and maintenance. You can then work for EPC contractors or install home systems. Suits fit people comfortable at height.

Hands-on roadmap
Roadmap
- Step 1Lesson
DC electrical safety, roof work & lightning protection
Panels are live whenever there is light and DC arcs are hard to quench; harness and temporary rails on metal roofs; earthing and surge protection for the system.

- Step 2Lesson
Grid-tied, off-grid & hybrid systems
Mono PERC and TOPCon panels, grid-tied and hybrid inverters, LFP batteries; Voc, Isc and Vmp ratings; check current connection rules with the local power company first.
Requires: DC electrical safety, roof work & lightning protection
No English content for this step yet.
- Step 3Skill
Roof survey & system sizing
Measure orientation, tilt, shading and purlin structure; size kWp from power bills; design strings with the inverter maker's tool without exceeding input voltage.
Requires: Grid-tied, off-grid & hybrid systems
- Step 4Skill
Mounting rails & panels
Fix metal-roof clamps, L-feet and aluminium rails; seal screw holes with proper sealant; torque mid and end clamps correctly, never step on panels and crack cells.
Requires: Roof survey & system sizing

- Step 5Skill
DC string wiring, combiner boxes & inverters
Crimp MC4 connectors with the right tool, measure each string Voc before connecting; fit DC and AC boxes with fuses, breakers and SPDs; commission Huawei, Growatt, Solis or Deye inverters.
Requires: Mounting rails & panels

- Step 6Skill
Battery storage, monitoring & maintenance
Connect LFP batteries to hybrid inverters and set self-consumption priority; monitor via FusionSolar or ShinePhone; clean panels, use thermal imaging for hotspots, retighten lugs.
Requires: DC string wiring, combiner boxes & inverters

- Step 7Project
Install a complete 5–10 kWp home system
Survey, design and install rails, panels, inverter and battery on a townhouse; commission with voltage, insulation and first-day yield checks and hand over documents to the owner.
Requires: Battery storage, monitoring & maintenance

- Step 8Certificate
Safety certification, quoting & finding projects
Complete electrical and working-at-height safety training as required by employers; inverter maker training certificates; quote per kWp and calculate payback for customers.
Requires: Install a complete 5–10 kWp home system
