Background

A South African installer building for a market that rewrites its own rules

01Market

Built for the South African grid

South Africa's solar boom is shaped by load shedding, Eskom and municipal tariffs that vary by suburb, and feed-in rules that are still being written. Every commercial and residential project has to be designed against a moving target.

02Operation

Operations across residential and C&I

Energy4All designs and installs solar systems for homeowners and businesses across the country, from single-phase backup to commercial PV with storage.

03Standard

Proposal-led sales motion

The team competes on the quality of the proposal in front of the client, not just the price at the bottom of it. Accurate engineering, clear savings, professional design.

04Partnership

solarVis as the design and proposal layer

Energy4All chose solarVis to run design, feasibility, and proposal generation on a single platform with South African tariffs and regulations already baked in.

Challenge

Designing accurately while South African tariffs and rules keep moving

Designing a solar system in South Africa means modelling Eskom tariffs, municipal Time-of-Use schedules, NERSA-aligned compliance, and the local export rules attached to each suburb. Generic design tools force teams to rebuild that logic by hand on every project. Energy4All needed a faster way to put proposals in front of clients without losing accuracy or compliance every time the regulator updates a rule.

Solution

A single platform with South African tariffs and regulations built in

Energy4All deployed solarVis across its operations team. The platform's South Africa tariff and regulation pack feeds straight into feasibility, so every proposal reflects the right tariff structure, export rule, and compliance assumption from day one. The 3D design and proposal generator close the loop, turning that data into branded, visually impressive documents that clients sign.
