Savings & buying
What should I tell my insurer after installing home solar in South Africa?
Tell them you added PV, inverter and battery, keep the CoC and serial list, and ask whether the schedule needs an endorsement for location and sum insured — before a storm or theft claim teaches you the hard way.
Updated 27 October 2026 · Illustrative ranges — not a formal quote or legal advice.
Answer first: A hybrid system is a capital asset on your roof and in your garage. Insurers price what they know. Notify after commission, confirm whether modules, inverter and lithium pack sit under buildings, contents or a specified-item endorsement, and photograph the array after the first serious storm.
What to disclose (simple checklist)
- Date of install and installer / CoC issuer name.
- PV kWp, inverter kW, battery usable kWh and brand.
- Where the battery sits (garage, plant room, outdoor cabinet).
- Whether the system is grid-tied / SSEG registered.
- Any prior claims on the property that touch electrical or roof.
Hand the broker the CoC PDF and a one-page serial list. Roof penetration detail belongs with both the sparky and the insurer — roof warranties & penetrations.
Claims that actually happen in SA
- Hail and wind — cracked glass, lifted rails; Highveld and coastal belts.
- Theft — modules and copper on unsecured roofs; photos and serials help.
- Water ingress — poor flashing blamed on “the solar people”; keep before/after photos.
- Electrical incident — rare when CoC’d; DIY and grey imports complicate claims.
Gradual battery capacity loss is almost never a household insurance event — that is warranty / chemistry territory. Fire myths vs reality: Li battery fire myths.
Savings angle
Insurance is not the payback driver — self-use is. But an uninsured R150k–R400k+ hybrid (illustrative band) is a false economy. A modest premium delta is cheaper than arguing after a hail cell. Pair cover with bill discipline: costs & savings · bill still high.
EV wallbox on the same property
Fixed EVSE is a separate disclosure for many motor and household schedules. Keep the wallbox CoC with the solar pack — EV insurance · EV wiring & CoC.
Red flags
- Broker says “solar is automatically covered” with nothing on the schedule.
- Battery in a bedroom cupboard against OEM temperature guidance.
- No CoC, or DIY DC work on a grid-tied system.
- You wait until claim day to mention the array.
Educational only — not insurance advice. Get the endorsement in writing for your address.
How to talk to the broker without jargon
Lead with savings and asset protection, not fear. Say: we installed a grid-tied hybrid with X kWp PV, Y kW inverter, Z kWh usable lithium, CoC on file, battery in the garage. Ask them to confirm the sum insured still matches replacement cost including labour — module prices move, and labour to re-roof after hail is not free.
If the broker asks for a “solar certificate,” hand the CoC and the SSEG approval letter (when you have it). PV GreenCard is a quality programme artefact, not a substitute for the legal CoC — what is a CoC · PV GreenCard.
Tenanted properties and holiday homes
Landlords should keep install paperwork with the lease file and require tenants not to modify DB boards or add Mode 2 EV cables on shared circuits. Holiday homes with long idle periods still need monitoring — theft risk rises when the house is dark for months. Notify when the system is commissioned, not when you next renew.
After a claim — what helps
- Date-stamped photos of the array and battery before and after the event.
- Portal screenshots showing the system was online.
- Installer contact who can quote like-for-like replacements with the same BMS family.
- Serial list that matches the schedule endorsement.
Expandability language matters here: replacing with a random incompatible wall because “it was cheaper” can orphan the hybrid. Longevity and LV upgrade paths (e.g. Solar MD’s backward-compatible LV story under its SA warranty statement) are practical claims advantages — not brochure fluff.
Load shedding, generators and dual supply
If you keep a genset alongside the hybrid, labelling and changeover rules matter for safety and for claims after an electrical incident — ATS / changeover · dual-supply labelling. Insurers dislike informal changeovers that back-feed the grid.
Document firmware update habits and who holds portal admin rights. When you sell, transfer those credentials with the compliance file so the buyer’s insurer is not starting from zero.
Who pays when a module is obsolete?
Like-for-like replacements age out. Ask the installer which wholesaler can still source the frame family, and whether the inverter accepts a mixed string under the OEM rules. Keep that note with the insurance file so a claims adjuster is not inventing a bill of materials under pressure.
What “sum insured” usually needs to cover
Ask the broker whether the endorsement covers modules + rails + inverter + battery + labour to reinstate, or only hardware invoice value. Hail that cracks ten modules on a double-storey roof is a labour story as much as a glass story. If you financed the system, check whether the credit agreement expects comprehensive cover — banks and asset-finance houses often do.
Keep a replacement-cost note updated when you expand the array or add a second wall of lithium. An endorsement written for a 5 kW day-one hybrid will under-state a later 10 kWh usable upgrade.
Storm season habits that protect savings
- Photograph the array and flashings after the first serious Highveld hail or Cape north-wester each season.
- Clear leaf dams against rails so water does not sit on penetrations — roof penetrations.
- Do not walk modules to “check” after a storm; call the installer if glass looks starred.
- Confirm the monitoring portal still reports — silent systems hide theft and string faults.
These habits cost almost nothing and keep claim files clean. They also protect the bill savings you modelled on costs & savings.
Holiday homes, Airbnb and tenanted stock
Idle properties still need disclosure. Theft risk rises when the house is dark for months; require tenants and cleaners not to open the DB or “reset” the hybrid without a written SOP. Guest-house and short-stay hosts should keep CoC and serial PDFs in the property pack the same way they keep gas CoCs — see the new desk answers on holiday-home and Airbnb stacks when you publish them alongside this page.
Sectional-title schemes: trustees may want proof of insurance when you add common-property cable or a plant-room battery — sectional-title solar.
Documents folder (one place)
- CoC (electrical) and any gas CoC if heat-pump work touched refrigerants via a separate trade.
- Serial list with photos of nameplates.
- SSEG approval / acknowledgement letter.
- Installer invoice and warranty registration confirmations.
- As-built single-line and portal admin credentials.
Hand that folder to the buyer when you sell — it shortens their insurer conversation and protects your sale narrative. Red-flag quotes that never produce these papers: installer red flags.
When the insurer asks about “quality marks”
PV GreenCard and similar programmes are useful quality signals; they do not replace the legal CoC or the schedule endorsement. Bring both if you have them — PV GreenCard · CoC. NRS 097 type-tested inverters help municipal SSEG files and, indirectly, show the system was designed for grid rules — NRS 097.
Disclosure checklist after install
- Notify the insurer with system kWp, usable battery kWh, inverter brand and serial list.
- Confirm whether the policy treats solar as fixtures and the battery as specified equipment.
- Ask about excess for storm / theft / electrical damage separately.
- Store commissioning photos and CoC with the policy schedule.
