What this business's certifications actually buy you

This listing states: Wireman's Licence, COC issuer. Here is what each of those means in practice, and what it does not cover.

Certifications are self-declared on unclaimed listings and are not independently audited by SolarZA. Ask for the certificate number and check it with the issuing body before you sign anything.

What to ask Thusanang Solar before you sign

These questions are generated from what this specific listing does and does not tell us. They are not accusations - a gap in a directory record usually means nobody has filled it in yet - but they are the gaps you should close yourself.

• 1Warranty terms are not stated. Ask for three separately: the panel performance warranty, the inverter warranty, and the workmanship warranty on the installation itself. The third is the one that fails first and the one most installers do not put in writing.
• 2There is little or no public review history on file. Ask for two reference installations completed in the last year within 30 km of you, and phone them. A small review count is not a red flag on its own - plenty of good installers never chase reviews - but it does mean you have to do the verification yourself.

What solar is worth at this location

Midrand, Johannesburg averages 5.5 kWh/m²/day across the year, dropping to 4.4 in June. On those figures a 5 kW array with a 5 kWh battery - the most commonly quoted household system in South Africa - generates roughly 17.2 kWh on an average winter day, 25.0 kWh in summer, and about 7 829 kWh a year. Johannesburg has the best winter-to-summer balance of the big metros: June still delivers around 80 percent of the December figure, so a Johannesburg system carries a steadier share of the bill year-round than a Cape Town one of the same size. City Power requires registration of any embedded generation and an approved bi-directional meter, and has been actively auditing unregistered installations. Highveld summer hail is the underrated risk: confirm the panel carries a hail impact rating and that the household insurer has been told the array exists.
