What hail rating should solar panels have in South Africa?
Read the panel datasheet for IEC mechanical/hail impact test claims (commonly discussed in the 25–35 mm class range depending on brand and test) and declare the array to your insurer — Highveld storms can still exceed lab ice. Hail rating is not a substitute for mounting quality or insurance.
Updated 27 October 2026 · Illustrative ranges — not a formal quote, credit decision or legal advice.
Answer first: Ask for the datasheet page with the hail/impact test statement, keep it with the invoice, and photograph glass after the first severe storm — hail / insurance · declare solar · mono vs bifacial · panel lifespan.
What the number does not mean
- It is not a promise against every Highveld supercell.
- It does not cover poor clamps or flying debris from next door.
- It does not replace insurer declaration.
After a storm
- Stay off wet roofs.
- Photograph cracked cells / hot spots via monitoring if available.
- Open insurance and OEM paths in parallel when needed — claim steps · degradation / replace.
Mounting and tilt
Steeper tilts and quality mid-clamps reduce some flying debris risk but do not cancel ice physics — IBR mounting · tile mounting · tilt.
SA desk notes that keep quotes honest
Ask every partner for Incl. VAT line items, NRS-listed SKUs where relevant, and who owns metro paperwork after deposit. Compare at least two written scopes before you pay — read a quote · choose installer · NRS list · SSEG.
Worked homeowner checklist
- Photograph the DB, roof and meter before the survey.
- Export twelve months of kWh or summer+winter bills.
- Write Stage priorities (fridge, routers, lights) before shopping kWh.
- File CoC, warranties and SSEG refs in one folder after handover.

Tariff and fixed-charge reminder
Self-use savings sit on top of fixed charges that do not disappear. Model both before you celebrate a payback slide — fixed charges · monthly savings · export vs self-use · tariffs 2026.
Safety and paperwork close
- No DIY on dual-supply boards or MC4 strings.
- Keep dual-supply labels readable for inspectors.
- Register warranties before the deadline printed on the pack.

Monitoring and aftercare
Watch daily kWh, backup SoC before forecast Stages, and any new earth-leakage or isolation alarms. Export CSVs monthly so cloud portal changes do not erase your history — monitoring numbers · Wi-Fi dongle · SoC settings.
When to call vs when to wait
Call for burning smells, repeated RCD trips, zero production in full sun with isolators on, or firmware prompts you do not understand. Wait-and-log for single Stage-restore blips that do not repeat — fault codes · nuisance trips · MC4.
Sources homeowners should open themselves
Open the live metro SSEG page, the OEM manual PDF for your exact inverter SKU, and the tariff code on your latest bill before you argue with a salesperson. Screenshots age; primary pages change. Cross-check any rand band on this desk against those primaries the week you buy — metro tariffs · tariffs 2026 · NRS list · SSEG · SSEG cost.

Stage-season operating rules
- Know which breakers are essentials before the app says Stage 4.
- Pre-charge only as far as your written SoC policy — not 100% forever.
- After restore, glance at earth-leakage and isolation alarms before heavy loads.
- Keep a paper copy of dual-supply labels and OEM contacts in the kitchen drawer.

Aftercare calendar
- Month 1: confirm monitoring app + CSV export works.
- Month 3: visual roof/MC4 glance from the ground after storms.
- Month 6: reconcile bills vs production; check fixed charges.
- Month 12: warranty registrations, cleaning, SoC policy review.

Bottom line for SA homeowners
Treat this as a decision aid with named trade-offs, not a brochure. Demand Incl. VAT scopes, NRS-listed hardware where it applies, written SSEG ownership, and a backup board that matches how your household actually survives Stage. If a partner cannot explain those four items without slogans, keep shopping — get quotes · check a quote · read a quote · is solar worth it · payback · monthly savings.
Keep primary PDFs (metro, OEM, warranty) beside this article. When figures disagree, the live primary wins. Update your own notes after tariff changes each year — tariffs 2026 · metro tariffs · VAT on solar · bond finance · lease vs buy · selling with solar.
Worked datasheet checklist
- IEC impact / hail statement with ice diameter and speed.
- Glass type (single / dual).
- Frame and clamp compatibility notes.
- Warranty exclusions for storm acts.
File that PDF with the insurance declaration — warranties · hail claims · declare solar · panel lifespan.
Monitoring after storms
String current imbalance after hail can reveal cracked cells before you see them from the ground. Export the day-after CSV — monitoring · shade / optimisers · string vs micro.
Local follow-ups worth booking
Ask installers which panel SKU hail statement they actually stock this month — not a brochure cousin — read a quote · mono vs bifacial · panels hub.
Desk close — what to do this week
Photograph your DB and roof, export twelve months of kWh (or summer plus winter bills), write Stage priorities on one page, and request two Incl. VAT quotes that name SKUs, export mode, meter plan and who lodges SSEG. File CoC, warranties and insurer acknowledgement in one folder after handover. That pack beats any brochure PDF — get quotes · check a quote · read a quote · SSEG · CoC · declare insurance · warranties · choose installer · red flags · is solar worth it · payback · monthly savings · metro tariffs · load shedding · fixed charges.

Photo tip: after commissioning, take dated overview photos of every array face; insurers and OEMs move faster when pre-loss glass condition is obvious.
Confirm every figure on the live primary (metro PDF, OEM manual, insurer schedule) the week you spend money — desk ranges here are illustrative education only, not a quote or credit decision. Pair with quote literacy and check a quote before deposit.
Homeowner checklist before you spend
- Write the decision on one page: what problem this solves under Stage, what it costs in rand bands, and who signs the CoC.
- Ask the installer for the primary PDF (OEM, metro tariff, SSEG form) that backs any number on the quote.
- Photograph serials, labels and the DB before and after work — claims and warranty desks start there.
- Keep guest monitoring logins with the invoice so a future buyer or insurer can verify the plant.

Stage-weekend reality check
Model the worst Stage window you actually live through, not a brochure day. Essentials first, then comfort loads. If the plant cannot cover fridge, lights, fibre and one work laptop through that window, resize before you chase export credits — essentials · Stage strategy · Stage 4 battery · SoC settings · Stage table.
Documents to keep for five years
Invoice PDF, CoC number, dual-supply photos, export-limit screenshot, CT polarity photo, firmware version, and the guest portal login. When a fault or sale appears later, that pack beats a WhatsApp thread — labels · export limit · CT clamps · firmware · selling with solar.
Quick questions
Is 25 mm hail rating enough for Gauteng?
It is a common datasheet class — still insure and inspect after severe storms.
Do bifacial panels hail differently?
Glass-glass builds differ; read that datasheet, not a general blog.
Will insurance demand a hail rating?
Policies vary — declare plant and keep datasheets ready.
