How to Choose the Right Solar Installation Company?

Quick answer: choose a Durban solar installer who uses registered electricians and issues a Certificate of Compliance (CoC), registers your system with eThekwini, visits your home before quoting, uses reputable equipment, gives a fully itemised quote with written warranties, and offers proper after-sales support. Be wary of the cheapest quote. In solar, the savings usually come out of equipment quality, workmanship or support.

A solar system is one of the biggest investments you will make in your home or business, and it should run for 20 years or more. The installer you choose decides how well it performs, how safe it is, whether it is legally compliant, and who you can call when something goes wrong.

This guide walks you through exactly what to check, the questions to ask, and the red flags that point to an installer you should avoid.

Why your choice of installer matters so much

Two systems with the same panels and inverter can perform very differently depending on who installs them. A poorly designed or badly installed system can:

•       Produce less power than promised because of poor panel placement or shading

•       Corrode early in Durban’s humidity and salt air if the wrong fittings are used

•       Fail an electrical inspection, which can affect your insurance or the sale of your home

•       Leave you without support if the installer closes down or stops answering calls

Demand for solar has grown fast in South Africa, and with it the number of fly-by-night operators. A few checks before you sign will protect you from most of the problems we see when we are called in to fix other installers’ work.

Quick checklist: what to look for in a solar installer

1. Check their qualifications and compliance

This is the most important check, and the one most often skipped.

Registered electricians and a Certificate of Compliance

Every solar installation in South Africa must be signed off by an electrician registered with the Department of Employment and Labour, who issues an electrical Certificate of Compliance (CoC). The CoC confirms your installation meets the national wiring code. Without it you may have trouble with insurance claims, municipal registration and selling your property.

Ask whether the installer’s own team includes registered electricians or whether the electrical work is subcontracted, and ask to see the electrician’s registration.

eThekwini SSEG registration and approved inverters

If your system is connected to the grid in Durban, it must be registered with eThekwini Municipality as a small-scale embedded generator (SSEG) before it is connected. The municipality requires an approved inverter and a CoC, and it installs a bi-directional meter so that power you export can be credited to your account. Registration typically adds a few weeks to the process.

A good installer will handle the application for you and confirm the inverter they are quoting is on the approved list. If an installer tells you registration is optional, walk away.

PV GreenCard

The PV GreenCard is an industry quality programme run by SAPVIA, the South African Photovoltaic Industry Association. Installers registered with it provide an as-built report documenting how your system was installed and what equipment was used. It is not compulsory, but it is a useful sign that an installer takes quality seriously.

2. Look for experience and proven local results

Experience matters in solar because most problems come from design and workmanship, not from the equipment itself. Ask:

•       How long have you been installing solar systems?

•       How many installations have you done in Durban and the surrounding areas?

•       Can you show me examples of systems similar to mine?

•       Can I speak to a past customer?

An experienced local installer will answer easily and will have a portfolio of real, nearby installations to show you.

3. Insist on a site assessment and a custom design

No two homes use electricity the same way, so be wary of anyone who pushes a fixed package without visiting your property. A proper installer will look at:

•       Your electricity usage: your bills, and when during the day you use the most power

•       Your goals: cutting your bill, backup power during outages, or both

•       Your roof: its condition, direction, angle and available space. North-facing roofs at a 25 to 30 degree tilt generally perform best in Durban.

•       Shading: from trees, neighbouring buildings and chimneys across every season, not just on the day of the visit

•       Future needs: a pool pump, an electric vehicle or a growing family, so the system can be expanded later

•       Your budget: with options that show what each extra rand buys you

The result should be a written design that explains how much power the system will produce over a year and why each component was chosen.

4. Check the quality of the equipment

Your quote should name the brand and model of every major component. If it says “or equivalent”, ask exactly which products you will get. Then spend a few minutes looking up reviews and warranty terms for each one.

Solar panels

Look for panels from established manufacturers, often referred to as Tier 1, with a strong local presence and warranty support. Examples include JA Solar, Canadian Solar, Jinko and Longi.

Inverters

The inverter is the heart of your system. Choose a brand with local technical support, available spare parts and municipal approval. Popular options in South Africa include Sunsynk, Deye and Victron.

Batteries

Lithium iron phosphate (LiFePO4) batteries are the standard choice for homes today. Check the warranty period and the number of cycles it covers. Common brands include Dyness, Hubble, Pylontech and Deye.

5. Compare quotes properly, not just on price

It is sensible to get two or three quotes. Just make sure you are comparing like with like. A good quote is itemised and includes:

•       Brand, model and quantity of panels, inverter and batteries

•       Mounting system, cabling, protection devices and DB board work

•       Labour, the CoC and eThekwini registration

•       Expected yearly production

•       Product and workmanship warranties

•       Payment terms and an installation timeline

Why the cheapest quote can cost you more

A quote that is far below the others is usually cheaper for a reason. Common shortcuts include:

•       Unbranded or low-grade components that don’t meet South African standards

•       Unqualified subcontractors, leading to poor workmanship and safety risks

•       Missing items such as the CoC, registration or proper surge protection

•       No after-sales support once the installer has been paid

•       An undersized system that falls short of your needs and has to be redone

6. Make sure they design for Durban’s climate

Durban’s heat, humidity and salt air are harder on a solar system than conditions inland, and installers from other provinces don’t always account for them. Your installer should:

•       Use corrosion-resistant fittings near the coast. Homes in Ballito, Umhlanga, La Lucia and other seaside areas need marine-grade stainless steel bolts and clamps.

•       Seal connections properly. Weatherproof junction boxes and UV-resistant conduit stop moisture causing faults over time.

•       Plan around trees. In leafy areas such as Kloof, Hillcrest and Westville, shading needs careful design, sometimes using optimisers or microinverters.

•       Secure the system for storms. Mounting must be rated for strong winds and fixed without damaging your roof’s waterproofing.

Coastal systems also need more regular cleaning to stop salt building up. Our solar panel maintenance guide explains how often.

7. Understand the warranties

There are two kinds of warranty, and you need both in writing:

•       Product warranties come from the manufacturer. Panels typically carry a 10 to 15 year product warranty and a 25-year performance warranty. Inverters typically carry 5 to 10 years and lithium batteries around 10 years.

•       A workmanship warranty comes from the installer and covers the installation itself: wiring, mounting, roof penetrations and connections.

A manufacturer’s warranty is only as good as the installer who helps you claim on it, so ask who handles warranty claims and how long they typically take.

8. Read reviews and check their track record

Look beyond the installer’s own website. Check their Google reviews, HelloPeter and local Durban Facebook groups. Read the negative reviews as well as the positive ones, and pay attention to how the company responds. Every installer gets the occasional complaint; a good one owns the problem and fixes it.

9. Ask about after-sales support and maintenance

Your relationship with your installer should continue long after installation day. Ask whether they offer:

•       A direct number to call if something goes wrong

•       Annual maintenance and system health checks

•       Remote monitoring of your system’s performance

•       Upgrades, such as adding panels or batteries later

If an installer can’t tell you what happens after they leave, that tells you what you need to know.

Red flags to watch out for

•       A quote given over the phone without a site visit

•       Pressure to sign today to secure a special price

•       A large upfront deposit with no written contract

•       No CoC, or a CoC charged as an optional extra

•       Claims that eThekwini registration isn’t necessary

•       Unbranded equipment or “equivalent” products that are never named

•       No physical business address, landline or company registration

•       No reviews, or a pattern of unanswered complaints

Questions to ask before you sign

1.     How long have you been installing solar, and how many systems have you installed in Durban?

2.     Will your own registered electrician issue the CoC?

3.     Will you handle the eThekwini SSEG registration, and is the inverter on the approved list?

4.     Can you show me the design and the expected yearly production?

5.     Exactly which brands and models are you quoting?

6.     What product and workmanship warranties do I get, in writing?

7.     Who do I call if something goes wrong, and how quickly will you respond?

8.     Can the system be expanded later?

9.     Can I speak to a recent customer?

Frequently asked questions

How do I know if a solar installer is legitimate?

Check that they use registered electricians, issue a CoC, have a physical business address, provide an itemised written quote and have genuine reviews you can verify on Google or HelloPeter.

Do I need to register my solar system with eThekwini?

Yes, if your system is connected to the grid. eThekwini requires small-scale embedded generators to be registered, with an approved inverter and a CoC. Your installer should handle the application for you.

What is a solar Certificate of Compliance?

A CoC is issued by a registered electrician to confirm your installation meets South Africa’s electrical safety standards. You need it for municipal registration and it supports insurance claims and property sales.

How many quotes should I get?

Two or three is usually enough. Make sure each quote covers the same items so you can compare them fairly.

How long does a solar installation take?

Most home installations take one to two days on site. Grid-tied systems need extra time for eThekwini registration and meter installation, which typically adds a few weeks.

Do I need batteries?

Only if you want backup power during outages or want to use solar energy at night. A system without batteries still lowers your daytime electricity costs. A good installer will explain the trade-offs for your home.
