7 Things To Look Out For When Choosing A Backup Power Supplier in SA

The increasing demand for backup power and solar PV systems in South Africa has attracted a wave of new suppliers entering the market to cater to the growing needs of homes and businesses.

However, one of the significant challenges arises from the fact that many of these emerging suppliers lack the certification as qualified electricians, which is vital for ensuring a top-notch installation that aligns with rigorous electrical, building, and safety standards. With a proliferation of so-called "solar installers" seemingly available on every street corner, navigating through the clutter can be an overwhelming task.

Considering that solar PV or battery backup systems represent a substantial investment for any home or business, it is crucial to exercise caution. The technical complexities involved often leave customers uncertain about what aspects to prioritize when sourcing a reputable installer. Consequently, this vulnerability exposes them to a multitude of potential issues, ranging from malfunctioning systems and costly repairs to non-compliance, electrical hazards, and even the risk of falling victim to scams that can erode hard-earned savings.

Here’s what experts are saying you should look for in a reliable battery backup and solar PV supplier:

1. Will you be getting an Electrical Certificate of Compliance (CoC) for your installation?

According to the Occupational Health and Safety Act, all electrical installations should be done by a qualified and registered electrician. One of the first steps in selecting a power backup system is to ask the installer if they are an Electrical Contractor, registered with the Department of Labour, and whether they will be issuing an Electrical Certificate of Compliance (CoC) after completion of your installation. This CoC is a legal requirement for any electrical installation or alteration. It certifies that the work done has been done according to the current regulations required in the South African National Standards (SANS).

A copy of this CoC would also be required by insurance companies to cover and protect your valuable investment.

2. Ask for details of previous installations

Make sure the supplier can provide you with feedback, photos and/or customer references of previous solar or backup installations they have done in the past. Even for the non-technical buyer, it is easy to distinguish between a tidy installation and one with loose and untidy wires. A good installation that adheres to all regulations and best practice design and installation practice will last longer, be safer and give you peace of mind that you are dealing with someone proud of their workmanship.

3. Is the installer an experienced solar or battery installer?

While many registered and qualified electricians have recently ventured into installing alternative energy systems, it is important to note that proficiency in neat electrical installations and adherence to SANS electrical standards may not guarantee an accurately sized and designed system. It is not uncommon for inaccurately sized or poorly designed systems to fall short of delivering the promised results. Consequently, this can lead to unexpected issues and necessitate additional costs to rectify or upgrade the installation by an expert in the field.

Additional certification including PV GreenCard by SAPVIA or PQRS Solar PV will give you a good indication of whether your qualified electrician is committed to designing and installing the best-performing system for you.

4. Look at where your system will be installed

The SANS 10400 Part T Building and Fire Regulations state that any lithium battery above 1kWh in capacity may not be installed in a living area such as a bedroom, kitchen, office or other similar spaces. The battery will change the occupancy of the room to J1, which requires at least a 120-minute fire break to other occupational areas.

Since your home should already be built according to SANS 10400 standards, your garage will already have a 120-minute fire break to the house and be the perfect place to install your new solar or battery backup system. If you do not have a garage, an experienced supplier would provide you with alternative options like a weatherproof outdoor ventilated enclosure.

Although professionally installed systems have all the required surge protection, fuses and other safety mechanisms to reduce the risk of a fire, any installer who doesn’t comply with these standards should raise red flags.

This is what a reliable installation looks like.

5. Will you have ongoing support after the installation?

After the installation of your system, you should have a mobile app on your phone where you can monitor your system performance, battery levels, power usage, etc. This information can help you to change your electricity usage patterns and habits, without disrupting your life, to get the most out of your system. This could mean getting better PV yield from your solar PV or your batteries lasting for a longer duration during a power outage or load shedding.

A reputable installer will be there for you in the long run, remotely monitoring your system performance, providing training, answering any questions you may have and advising you on how you can get the best return on your investment.

6. Are you using a residential installer for a commercial system?

If shopping around for a backup power or solar system for your business, make sure that the installer has experience with commercial systems. Can they calculate your financial savings, including electricity and generator fuel savings? Do they know how to integrate the proposed system with your existing solar PV, diesel generator and other power sources?

Backup power and solar systems for business is a financial decision while a system for home use is more about the convenience and comfort of not sitting in the dark during load shedding. If the financial savings calculations do not make sense for a business, there is no use replacing your diesel generator with a battery backup and solar PV system.

Make sure the supplier has the required experience and financial know-how to design and propose the best solution for your business.

7. Cash or Finance Options

Installing a backup power or solar PV system shouldn't be a financial burden. It's important to explore affordable options and consider suppliers that offer flexible financing plans. Remember that you are essentially buying your electricity up front for the next 15+ years when installing solar PV. By financing and spreading the cost over time, you can protect your home or business from the impact of load shedding without straining your budget.

Ask your installer about the available financing options tailored to your needs, ensuring that you can install a properly sized system that aligns with your budgetary requirements.
