Voltara Consulting provides independent technical advisory across electrical infrastructure and solar & battery storage systems — helping owners and operators understand exactly what they have, and what to fix.
We assess, design-review, and advise across both electrical infrastructure and solar & storage systems — so findings in one area are never viewed in isolation from the other.
Independent review of LV and HV installations, switchgear, protection coordination, and distribution design for compliance and fitness for purpose.
Assessment of protection systems, fault records, earthing, and conformance to SANS and utility connection standards.
Independent construction monitoring and technical supervision for electrical works, on behalf of the client — not the contractor.
Health, safety, and technical compliance auditing against statutory and industry requirements.
Generation and yield analysis against design basis, degradation review, and inverter performance evaluation.
BESS capacity verification, cycle behaviour, dispatch strategy, and state-of-health assessment against specification.
Independent evaluation for investors, lenders, and developers assessing solar and storage assets before commitment.
Actual versus projected savings, tariff impact, and quantified root-cause attribution for underperforming systems.
Every engagement follows the same disciplined sequence — regardless of whether the question is electrical, solar, or both.
We define exactly what needs answering — a fault, an underperforming asset, a compliance gap — before any site work begins.
On-site inspection, data review, and technical testing, carried out without ties to the original supplier or installer.
Findings are traced to their cause and delivered in a clear, evidence-based report — written for both engineers and decision-makers.
A prioritised action plan with practical next steps, so the client knows exactly what to do — and why.
Voltara Consulting was founded by Ricardo van Tonder — a qualified electrician and construction professional whose career spans HV substation work, industrial automation, utility-scale solar delivery, and executive-level project leadership.
That range is the point: most electrical problems on-site have a solar or storage dimension, and most solar underperformance traces back to the electrical installation underneath it. We assess both because they are rarely separate.
Whether it's an electrical fault, an underperforming solar system, or a project that needs independent oversight — reach out. We typically respond within 24 hours.
