What should I do if hail or a storm damages my solar panels in South Africa?

Answer first: Treat hail and wind damage as an insurance + safety event first, a warranty event second. Module performance warranties rarely pay for smashed glass; the household policy and (sometimes) workmanship cover do.

First 24 hours

1. Keep people and pets off the roof and away from fallen glass.
2. If safe, shut down via the documented isolator sequence from your handover pack — or wait for the installer.
3. Photograph every visible module, flashing, and any water ingress indoors.
4. Export monitoring screenshots (underperforming strings, fault codes).
5. Open insurer and installer tickets the same day with the date/time of the storm.

What policies usually care about

• Whether solar was disclosed after install — tell your insurer.
• Mounting method and whether penetrations were flashed to roof-warranty rules — roof penetrations.
• Serial numbers matching the commissioning list (theft and damage claims both need this).
• Whether micro-cracks appear later as string mismatch — schedule a re-test after the weather clears.

Savings impact while you wait

A damaged string can quietly erase daytime self-use for weeks. If you rely on solar to offset 350–450 c/kWh import blocks, log the lost kWh estimate for the claim. Temporary zero-export or reduced output settings may be needed until replacements land — monitoring · monthly savings.

Replacement parts logistics

Matched modules matter for string current. Ask the installer which SA wholesaler can supply the same or an approved substitute (Herholdt’s, ARB, Voltex, ACDC, DBS, SONAH and solar specialists). Mix-and-match leftovers without a design note create new mismatch losses — wholesalers · panel lifespan.

Prevention notes for new quotes

• Ask for module hail ratings / test class on the datasheet summary.
• Confirm SPD / bonding scope — surge & lightning.
• Keep a digital folder: CoC, SSEG, serial list, photos at handover — selling with solar uses the same pack.

Body corporate / estate angle

In sectional title, clarify whether modules sit on exclusive-use areas or common property and whose insurer leads. Trustees hate surprises after hail — send the same photo pack you send your household insurer — sectional title · landlord / tenant.

How damage shows up beyond smashed glass

• Hairline cracks that look fine until IR / string tests.
• Dislodged flashings and quiet roof leaks into ceilings.
• Bent rails that stress neighbouring modules.
• Water into MC4s causing ground-fault trips days later.
• Inverter isolation alarms after wet storms even when glass looks intact.

Log everything. Underperformance without photos is hard to claim — fault codes · monitoring · cabling notes.

Warranty vs insurance vs workmanship

Read your schedule. Disclose the system after commissioning — insurance disclosure · warranties overview.

Theft crossover

Storm debris events sometimes coincide with opportunistic theft of loose modules or copper. Serial-number lists and install photos are your evidence pack for both insurers and SAPS case numbers. Keep spares logistics honest — do not invent street prices for BlueNova or other packs from conflicting OOS retailer pages when replacing storage; ask for a dated in-stock quote.

Temporary generation plan

While waiting for modules:

1. Isolate damaged strings safely via the installer.
2. Retune self-use expectations so you do not grid-charge the battery on expensive peaks unnecessarily.
3. Defer non-essential EV daytime top-ups to public DC only if the home deficit is severe — compare R/kWh first.
4. Track imported kWh for the claim narrative.

For new builds — storm-minded quoting

• Module mechanical / hail test class on the datasheet summary page of the quote.
• Rail and clamp torque values in the handover pack.
• SPD and bonding scope included, not optional — surge protection.
• Clear who climbs the roof after storms (installer vs roofing contractor).

Buyer protection mindset: read a quote · red flags · panel lifespan.

Worked claim timeline (illustrative)

1. Hour 0–6: Safety isolation, photos, insurer + installer tickets.
2. Day 1–3: Assessor / installer roof inspection when weather clears; string IV or app diagnostics.
3. Week 1–3: Module order via SA wholesale channel; temporary production on healthy strings.
4. Replacement day: Match tilt/azimuth, re-torque, update serial list, re-enable monitoring alerts.
5. Close-out: Insurer invoice pack, warranty registration for new modules, roof leak check after first rain.

Keep every email. Gaps in the paper trail slow payouts and confuse body-corporate trustees — landlord / tenant · sectional title.

If the inverter also died, separate the surge/hail narratives: modules vs electronics may sit on different policy sections — surge protection · inverter replacement.

Monitoring tells you what eyes miss

Compare string currents and daily kWh to the week before the storm. A 15–30% unexplained drop on one MPPT with intact-looking glass is classic micro-crack behaviour. Share those charts with the assessor; they justify module-level replacement instead of “wait and see.”

If you lack historical monitoring, say so honestly and ask the installer for a post-storm IV curve test. Going forward, enable alerts — numbers to watch · MPPT.

Coastal wind-driven rain after hail also tests flashings; check ceilings and document stains early for the roof section of the claim — roof penetrations · roof suitability.

Keep expectations adult: insurers pay per policy wording; performance warranties still will not rebuild smashed laminate. The win is a complete file and a fast return to self-use kWh that beat weak export credits.

Do not accept a verbal “we’ll sort modules later” without serials, photos and a written temporary isolation plan. Lost generation is a rand figure on a 350–450 c/kWh import block — write it down for the claim.

After close-out, update your sale file with new serials so the next transfer does not inherit a mismatched bill of materials. Related: panel lifespan · cleaning.

Primary habit: photo everything, notify early, restore self-use fast — export credits will not repay a season of cracked glass on a Highveld summer municipal bill at peak import rates.

Finance angle while generation is down

If a bond energy loan repayment assumed uninterrupted self-use, a multi-week outage after hail can temporarily invert cashflow. Ask the lender whether payment holidays exist; keep the claim number on file. Rebuild the savings model once serials are restored — bond finance · monthly savings.

Quick questions

Does the 25-year panel warranty cover hail?

Usually no — performance warranties address gradual output fade under normal conditions. Impact damage is typically an insurance / workmanship matter.

Can I claim if I never told my insurer about the solar?

Disclosure failures cause claim fights. Notify the insurer after install and keep proof — do not wait for a storm.

Should I accept any replacement module?

Prefer same model or an installer-engineered substitute that preserves string design. Random leftovers can create mismatch losses.

After the storm — evidence order

1. Wide and close photos before touching modules.
2. Portal yield screenshot for the storm day.
3. Broker / insurer notification with serial list.
4. Installer safety assessment before re-energising strings.
