Renewable energy solutions for a sustainable tomorrow
We work alongside facility managers and O&M teams across South Africa. These are their words about how our maintenance routines, grid compliance checks and troubleshooting support have held up on site.
Plant Manager, Free State
"We had a recurring F28 fault on one of our SG110CX units that the previous contractor could not pin down. Adani's engineer walked us through the string voltage checks and found a failing DC switch in the combiner box. That single diagnosis saved us a full inverter replacement."
EPC Project Lead, Western Cape
"Their commissioning checklist for bifacial string sizing caught a potential overvoltage issue before we energised the array. Cold morning temperatures at our site would have pushed the string voltage past the inverter limit. They recalculated the string configuration and we avoided a costly rework."
Facility Manager, Gauteng
"The thermal scan of our combiner boxes flagged two loose terminations that we would not have found until they failed. The report was clear enough for our maintenance team to act on immediately. This is the kind of preventive work that keeps our plant running through summer peaks."
We do not publish client names or site coordinates without permission. What we can share is the nature of the work: fault diagnosis on string inverters, grid code compliance documentation for municipal approval, soiling loss assessments on bifacial modules and battery dispatch logic reviews. If you are commissioning a new plant or troubleshooting an existing one, these are the conversations we have every week.
Most solar content reads like a datasheet or a sales pitch. We write from the combiner box, the inverter screen, and the commissioning log. That difference shows up in how our readers handle their next fault code or grid audit.
Every post on this site comes from a documented site visit, a logged fault, or a commissioning report. When we describe an F28 trip or a string mismatch, it is because we have traced it with a multimeter, not because we read about it in a brochure. That means the troubleshooting steps are the ones that actually work in the field.
Eskom grid code compliance, municipal approval paperwork, and protective relaying coordination are not abstract topics here. We cover the specific forms, the submission sequences, and the relay settings that apply to distributed PV in South Africa. If you are commissioning a plant in the Eastern Cape or the Karoo, the guidance fits your context.
We do not push a particular inverter brand or module manufacturer. Our advice is based on what keeps plants running safely and within code. When a component is failing across multiple sites, we say so. When a cleaning schedule is unnecessary, we tell you how to measure that instead of selling you a service.
Facility managers and EPC contractors come back to this knowledge base because the checklists and fault trees save them hours on site. When a plant operator needs to verify string sizing before winter or log performance ratio data properly, they know where to find a practical method. That is the kind of trust that does not need a flashy statistic to back it up.
If you want to see how we approach a specific problem, start with our field notes on inverter fault codes and string sizing. They show the level of detail you can expect across the rest of the site.
Read our approach"The F28 guide saved us a full day of guessing. We followed the DC bus check sequence and found a failing switch on the second string. Straightforward and accurate."
"Finally a resource that treats grid compliance like a practical task, not a legal lecture. The municipal submission checklist was exactly what our team needed."
"We used the soiling measurement method on a bifacial site in the Karoo. The data showed cleaning was only needed twice a year, not quarterly. That changed our budget."
Long-term relationships with EPCs, panel suppliers and electrical contractors keep our maintenance work grounded in real site conditions.
These are the teams we regularly commission plants with, troubleshoot alongside, and exchange fault logs with. No formal endorsements, just working relationships that show up in how we solve problems.
