Solar Installation, Upgrades & Repairs in Gauteng

Ndlovu Electrical Services installs residential solar systems for homeowners who want to use more solar energy and provide backup power for selected household circuits. We start by discussing your electricity usage, the appliances you want to support and your budget.

The assessment considers roof space, shading, electrical supply and installation positions for the inverter and batteries. We then recommend a system layout and explain the proposed scope. Whether you need a hybrid solar installation or a system planned for a property with limited grid access, the design is based on your loads and site conditions.

We assist businesses with solar installations planned around operating hours, daytime electricity demand and essential equipment. A commercial solar assessment helps establish the proposed solar capacity, battery requirements and integration with the existing electrical installation.

For industrial and three-phase premises, we review the supply arrangement, major loads, roof or installation space and the intended role of backup power. The proposal sets out the installation scope and assumptions so you can assess the project against your business requirements. Potential savings depend on consumption, tariffs, system design and operating conditions.

An inverter and battery backup system can supply selected circuits when the grid is unavailable, even where solar panels are not part of the initial installation. We help you identify priority loads such as lighting, refrigeration, internet equipment and essential business devices.

The proposed inverter capacity and battery storage are selected according to the loads and backup duration you require. We assess the distribution board, cable route and equipment location, then explain what the system is designed to support. Where suitable, we can consider future solar panel expansion during the initial planning stage.

We install solar panels for new systems and assess opportunities to expand existing installations. Adding panels may help a suitable system produce more daytime energy, but the proposed array must be checked against the inverter's input limits and the existing panel arrangement.

Our assessment considers panel specifications, available roof area, shading, mounting requirements and cable routes. We explain whether an expansion can work with the existing equipment or whether other changes are needed. The quotation identifies the panel installation scope, mounting and associated electrical work.

We assist with new solar battery installations, replacement batteries and assessments for increasing storage capacity. Additional battery storage may extend backup time for an agreed load, depending on usable capacity, inverter limits and how the system operates.

Before recommending an upgrade, we review the existing inverter, battery model, communication requirements and manufacturer guidance. We also consider the condition and age of existing batteries, installation space and charging capability. We explain compatible options and the changes required before quoting.

If your electricity needs have changed, we can assess whether your existing solar or backup system can be expanded or requires equipment replacement. An upgrade may involve a larger inverter, additional battery storage, more panels or changes to the circuits supported by the system.

We review the complete installation before recommending equipment so the inverter, batteries and solar array can work together within their requirements. The proposal explains which components can be retained, what needs alteration and the scope of testing and commissioning. A larger inverter alone does not increase available battery energy or solar generation.

We assist homeowners and businesses with diagnosing faults in solar and inverter backup installations. Common enquiries include batteries not charging as expected, inverter fault messages, unexpected system shutdowns and solar production that appears lower than usual.

We assess the reported symptoms, equipment information and installation before recommending corrective work. Depending on the findings, assistance may involve settings, connections, communication faults or replacement of suitable components. Where an internal equipment fault requires manufacturer or specialist attention, we explain the next steps and any separate repair arrangements.

Solar installations benefit from attention to their condition and operating performance. We offer panel cleaning and maintenance enquiries for residential and commercial properties, with the scope based on the installation, access conditions and reported concerns.

Maintenance can include a visual review of panels and mounting, checks of accessible installation components and a review of system performance. Cleaning requirements depend on dust, dirt and local conditions. We assess roof access and the appropriate work method before quoting. Cleaning results vary with the condition of the panels and other factors affecting generation.

If your system is not meeting your expectations, we can review how it is configured and how electricity is used at the property. The assessment considers your objectives, existing equipment, available monitoring information and the appliances connected to the system.

We can review charging schedules, battery reserve settings and load priorities where supported by the equipment. Recommendations may include setting changes, load management or a separate quotation for additional equipment. Changes are discussed with you and kept within equipment requirements. Improved performance depends on the system's capacity, condition and available solar energy.
