Solar Consulting & Inspections
Independent solar assessments, DB inspections, energy analysis, and compliance certificates for Cape Town homes and businesses.
Cape Town's abundant sunshine and the persistent reality of load shedding have driven thousands of homes and businesses across the Southern Suburbs to invest in solar power systems over the past several years. With so many installations happening rapidly — often by contractors who have since disappeared — a significant number of these systems are underperforming, non-compliant, or potentially dangerous. ASH Electronics provides independent solar consulting and inspection services to help property owners understand exactly what they have, whether it is safe, and how to get the most from their investment.
Our solar consulting service begins with a thorough site assessment and energy usage analysis. We review your municipal electricity bills, measure your actual consumption with calibrated monitoring equipment, analyse shading patterns, roof orientation, and structural loading, and then model the optimal system configuration for your specific property. Whether you are planning a new installation in Rondebosch, upgrading an existing system in Claremont, or simply trying to understand whether your installer delivered what they promised in Lansdowne, we provide the technical clarity and documentation you need to make informed decisions.
What distinguishes our solar work from a dedicated solar installer is that we approach every project from an electrical and compliance perspective first. Distribution board inspections, Certificate of Compliance issuance, load balancing, earthing, and surge protection are core electrical competencies — not afterthoughts. Because ASH Electronics also handles network infrastructure, UPS systems, and general electrical design, we see your property's energy needs as a complete picture. We serve clients in Lansdowne, Wynberg, Kenilworth, Plumstead, Claremont, Rondebosch, Tokai, Diep River, Retreat, and all surrounding areas across Cape Town's Southern Suburbs.

Frequently Asked Questions
How much does a solar panel inspection cost?
A professional solar panel inspection for a typical Cape Town home costs between R800 and R2,500 depending on the size of the system and the complexity of the roof access. The inspection includes a visual assessment of panels, mounting, wiring, and the inverter, as well as performance testing where possible. We provide a written report with findings and recommendations. Contact us for an accurate quote based on your specific installation in Lansdowne, Claremont, Rondebosch, or anywhere across the Southern Suburbs.
When do I need a Certificate of Compliance (COC) for my solar system?
A Certificate of Compliance is legally required in South Africa whenever electrical work is completed, including the installation of a new solar PV system or any modification to an existing system. You also need a valid COC when selling your home — the solar installation must be compliant as part of the property transfer. Banks and insurance companies increasingly request COC documentation for solar systems as well. ASH Electronics issues COC certificates for compliant installations and can bring non-compliant systems up to standard before issuing the certificate.
How long does a solar inspection take?
A standard solar and DB inspection for a residential property in Cape Town typically takes between 2 and 4 hours on site. Larger commercial systems or properties with complex electrical configurations may require a full day. The written report is provided within 24 to 48 hours of the inspection. We work around your schedule and serve homes and businesses in Lansdowne, Wynberg, Kenilworth, Plumstead, Tokai, Diep River, and the wider Southern Suburbs.
What does the solar inspection cover?
Our solar inspection covers the following areas: solar panel condition, soiling, shading, and visible damage; mounting hardware integrity and roof penetration waterproofing; DC wiring, conduit, and connection quality; inverter operation, error codes, and performance data; battery storage condition and state of health where applicable; distribution board connections, earthing, and surge protection; and overall system compliance with SANS 10142 and municipal requirements. The result is a detailed report you can use for insurance, property sale, or your own records.
How long do solar panels last and when should they be inspected?
Quality solar panels are warranted for 25 years and will typically still produce around 80% of their original output at end of warranty. However, annual inspections are recommended to catch issues early — loose connections, degraded bypass diodes, delamination, and soiling can all reduce output significantly without being obvious. An inspection every 12 to 24 months ensures your system is performing as expected and keeps your warranty claims valid. Many Cape Town homeowners who installed panels during the early load shedding surge in 2022 and 2023 are now due for their first professional inspection.
Can you estimate how much money my solar system will save?
Yes. As part of our solar consulting service, we analyse your electricity bills and conduct an energy usage measurement to determine your actual consumption profile across different times of day. We model this against your panel capacity, orientation, shading factors, and Cape Town's irradiance data to produce an accurate savings estimate. We factor in Eskom's tariff increases, municipal rates, and the cost of your system to calculate payback period and 10-year return on investment. This analysis is included in our full solar consulting report.
Do you handle the DB inspection separately from the solar inspection?
We recommend a combined solar and DB inspection because the two are electrically interdependent. A solar system feeds power back into your distribution board, and the DB must be configured correctly to handle bidirectional flow safely. Our engineers inspect both the solar installation and the DB in a single visit, checking that the isolation switch, protection devices, earthing, and load distribution all comply with current standards. This combined approach gives you one comprehensive report and a single COC that covers the complete electrical installation.
