What this business's certifications actually buy you

This listing states: ECA. 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 Transparent Energy 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.

• 1The listed certifications do not mention a Certificate of Compliance. A COC is a legal requirement for the electrical work, not an optional extra, so confirm in writing that one will be issued and registered in your name.
• 2Warranty 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.
• 3There 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.
• 4This business advertises a wide service area. Confirm who physically attends a callout at your address and what the response time is, because a wide footprint is often subcontracted and the warranty conversation gets complicated when the installing team is not the contracted party.

What solar is worth at this location

Durbanville, Cape Town averages 5.2 kWh/m²/day across the year, dropping to 2.9 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 11.3 kWh on an average winter day, 29.6 kWh in summer, and about 7 402 kWh a year. Cape Town has the sharpest summer-to-winter swing of any South African metro: a roof that clears 7 kWh per installed kW in January can fall under 3 in June. Size a Cape Town array on the June figure or the system will disappoint for exactly the four months you rely on it most. The City of Cape Town also runs its own small-scale embedded generation approval process and requires a registered, bi-directional meter before any grid-tied inverter is commissioned, which the City bills for separately. South-easter loading on exposed Atlantic Seaboard and False Bay roofs pushes mounting rail spans shorter than the manufacturer default.
