What a Solar Quote Must Include in South Africa (2026): A Complete Checklist
Print this or keep it open while quotes come in. You almost never buy from a wholesaler yourself — your installer does. Still ask where they source the products. A quote that cannot name the supply path, the warranty party, or the service desk in year four is incomplete.
Updated 27 October 2026
One question that changes the conversation: Ask your installer: “Where do you source this kit from, and how long has that wholesaler stocked this brand as a regular line?” Pair this page with how to read a solar quote for the line-item maths (kWp vs kW, usable kWh, payback cartoons). Use check a quote when a PDF is already in hand, or get another quote so you can score two proposals on the same sheet.
Must appear on every quote
If a line below is missing, treat the quote as unfinished. South African homeowners should be able to compare three quotes on the same sheet — same purpose, same usable storage, same compliance scope.
- System purpose stated (backup only, hybrid, or full off-grid intent)
- Inverter make, exact model, kW rating, single- or three-phase — and NRS / metro list status
- Battery make, model, usable kWh, chemistry, and BMS story
- PV modules: make, wattage, count, total kWp, and mounting type
- Expected daily production and backup runtime assumptions (stated, not vague)
- Price breakdown: equipment, labour, CoC, scaffolding, travel, VAT
- Who applies for municipal / NERSA / SSEG paperwork (and fees)
- Certificate of Compliance (CoC) included, and who signs it
- Commissioning report, serial numbers, and warranty registration in your name
- Payment schedule tied to milestones (deposit, delivery, commissioning)
- Workmanship warranty length and what it covers
- Named SA service path for each major component (not only a sales branch)
Cross-check paperwork language against what a CoC covers, SSEG registration, and warranties in SA.
Warranties that travel
Three different promises often get mixed into one slide. Separate them on the quote before you compare rand.
| Type | What it is | Ask |
|---|---|---|
| Manufacturer (OEM) warranty | Travels with the product. Named brand or SA entity. Keep the certificate. | Must name party |
| Distributor promotion / wrap | “10 years if bought with Brand X battery” can be a promo. | Ask if it survives when distribution changes — in writing |
| Installer workmanship | Covers how it was fitted. Separate from equipment. | Years and what voids it |
Also tick:
- Warranty party named for inverter, battery, and modules (OEM vs wrap)
- Any cloud / internet precondition for full warranty years is stated
- What happens after ~90 days offline, or a year offline, if the brand uses Safe Mode–style rules
- Loan / swap unit policy while a unit is in repair — who provides it
Field history vs warranty length
Most electronics work well for the first four years. They only really get tested from year five onward — heat cycles, firmware debt, connector fatigue, battery calendar ageing.
A 10-year warranty from a product that has only been shipping for three years means almost none of that promise has faced real mid-life failure yet. Early buyers are the guinea pigs for year-five and later. That is not always a reason to refuse — it is a reason to price risk, demand an OEM second door, and prefer supply houses that do not make a brand-new entrant their only hero SKU.
Company age and years of products in the field are different numbers. Prefer brands (and wholesalers) with enough installed years that year-five behaviour is already known — not only a clean year-one honeymoon.
Example used carefully: one fast-growing all-in-one brand was founded May 2022 and began commercial shipping mid-2023 — roughly three-plus years in the field as of late 2026, against typical 10-year marketing warranties. Ask the same question of every brand on the quote. A voluntary safety recall in a mature market (for example an ACCC recall in November 2025 on certain single-phase controllers) is a pattern question — check which SA SKUs are affected separately; do not treat a foreign recall as an automatic local ban.
- Years this exact platform has shipped at volume (global)
- Years of SA installed base / local claims history
- Written warranty length compared with years already in the field (under ~5 years in the field = still mostly untested mid-life)
- Enough field years that year-five and later failures are already known
- Any safety recall, mandatory redesign, or firmware derate in a mature market — verify SA SKUs separately
Where does the kit come from?
Public and installers should choose reputable wholesalers. Homeowners can — and should — ask the installer where the products are sourced. Installers should be ready to answer without defensiveness: supply path is part of the quote, not a trade secret.
- Named wholesaler(s) or supply houses for this quote
- How long that house has stocked this brand as a regular line (not a launch pallet)
- Whether access is tied to exclusivity or a loyalty / points programme
- Whether the installer would still specify this SKU if the points disappeared
- OEM service address and phone in SA for each major brand on the quote
It has happened in South Africa: a major wholesaler and a popular hybrid brand publicly ended their distribution relationship in January 2025. Inverter warranty repairs and loan units moved to the brand’s own service centre; a stockist window continued for a time; the manufacturer warranty was stated as unaffected. The lesson is not “never buy Brand X” — it is know the backup path before you need it. For a fuller supply-chain desk read, see reliable solar & electrical wholesalers and the installer checklist.
What a reputable wholesaler looks like
A good counter sells kit that has already done the hard years in the field. They stick to a short brand list, keep depth and training behind those lines, and do not make every new launch the only thing on the shelf.
- Years stocking the same brands — through field pain, not only launch week
- A select few brands with stock depth and real training behind them
- More than one option in a category when the job needs it (not a single hero SKU)
- Clear OEM / second door for claims if distribution changes
- Commissioning, fault and firmware training — not only roadshow points
- Patience on new entrants before making them the only push
Be wary of counters that flip hero brands every season, riding whatever is hot then chasing the next one. That is a short-term sales habit, not a supply house you want behind a ten-year roof. Exclusive lock-ins, brand-new “must install” launches with thin claims history, promo warranties that may not travel when the channel changes, and cloud-only fixes that never reach offline sites are the same warning light.
What long tenure looks like: ElectroMechanica (EM) has traded since 1984. Published catalogue timelines show distribution agreements that stretch across decades — Lovato and Finder from the late 1980s, Hager from the mid-1990s, later partners such as Delta and Socomec. Ask whether your installer’s supply house has that kind of years-with-brand story for the kit on your quote. More on supply path: reliable solar & electrical wholesalers.
Open stack vs closed umbrella
An open stack lets you swap a failed part without rewriting the whole system. Real SA examples: Victron (GX / Cerbo / small MPPTs) with Solar MD on 48 V, or GoodWe with BYD Battery-Box where that pairing is listed. A closed one-brand umbrella is neater on day one — you trade that neatness for less mix-and-match later, warranty language that often assumes one brand family, and features that need a healthy internet connection.
- Named open kit on the quote (e.g. Victron + Solar MD, or GoodWe + BYD where listed) vs a closed one-umbrella stack
- Can a competent electrician fit a different listed battery later without walking outside the warranty?
- Third-party parts clause: does the warranty exclude damage linked to non-brand parts?
- Commissioning offline-capable, or phone / cloud required?
- Firmware: local path available, or cloud-only?
- Panels quoted as full pallet or container modules — not single-panel street pricing
- Ask whether the warranty needs always-on internet
If you want the option to change battery vendor or keep a site offline for long stretches, say so up front — then score the quote against those requirements, not against launch-week pricing alone. More detail: open vs closed hybrid · hybrid brands.
Red flags
| Flag | Why | Stance |
|---|---|---|
| Cannot name the wholesaler | Supply path is part of the quote | Incomplete |
| Warranty length ≫ years in the field | Years 1–4 often look fine; you may be the pilot for year 5+ | Price the risk |
| No SA company or claims desk you can name | A warranty is only as good as who is still open when you claim in year six or seven | Walk away / re-spec |
| Only one hero brand this quarter | Ask what they specified last year — and why it changed | Probe |
| No OEM phone / address in SA | Sales branch is not a service desk | Incomplete |
| Extended warranty “with Brand X battery” — no letter | Get the party and terms in writing | Get paper |

Quick compare (score each quote)
- Equipment named to model level
- Wholesaler / supply house named — ask how many years with this brand
- Field years vs warranty years — past ~5 years in the field beats a clean honeymoon
- OEM second door — named SA service desk, not only wholesaler
- Stack openness — mix later without voiding cover?
- Cloud / offline rules — warranty and fixes if the site is offline
- Workmanship + CoC + registration — in your name, serials filed
Brochures rotate. Roofs don’t. Choose installers who can show the service path — and wholesalers who stay with products for years — not only the launch pricing.
Quick questions
What must a solar quote include in South Africa in 2026?
A complete quote names system purpose, exact inverter and battery models with usable kWh, PV make/wattage/count/kWp, production and backup assumptions, a VAT price breakdown, who handles SSEG/CoC, commissioning and warranty registration in your name, milestone payments, workmanship cover, and a named SA service path for each major component.
Should I ask my installer where they source the kit?
Yes. You almost never buy from a wholesaler yourself — your installer does. Still ask where they source the products and how long that house has stocked the brand as a regular line.
Why do field years matter more than a long warranty brochure?
Most electronics work well for the first four years. They only really get tested from year five onward. A long warranty on a short field history means you may still be the pilot for mid-life failures.
