If you are looking to install solar power in South Africa for a home, small business, or larger facility it pays to start with installers who are verified and transparent.
Below is a practical guide to identifying reliable solar installers, comparing pricing, and making informed choices about where to buy panels or full systems.
What Makes an Installer Reliable
Reliable installers share a few traits: certification, a proven track record, transparent pricing, and compliance with local regulations.
According to a 2025 directory of solar companies, top providers are typically members of recognized industry associations, have completed many installations with verified references, and offer warranties.
Good companies supply complete systems: panels, inverters, mounting hardware, and if needed batteries. They also provide documentation like compliance certificates and workmanship warranties, which protect your investment over time.
Examples of Established Installers
- Affordable Power Solutions (APS), APS advertises itself as a trusted installer for residential and commercial solar systems, offering design, supply, and installation, and promising long‑term reliability under warranty.
- Alumo Energy, listed among recommended installers in a national survey of solar companies, with experience in rooftop installations and good reputation for compliance.
- Distributors like Central Solar Supplies, not installers by themselves, but they supply solar panels and kits to certified installers, making them a useful source if you want to buy hardware for a professionally installed system.
These names don’t guarantee quality but they provide a starting point. Always cross‑check credentials, get references, and request full quotes before proceeding.
What Installation and Purchase Costs Look Like
Recent data on panel pricing shows that mid-range solar panels (around 330 W to 450 W) sold in retail stores remain a viable option for small to mid-sized installations. For example, some panels retailed online and in‑store at prices competitive with quality standards.
For a typical home solar installation, costs depend on system size, components (panels, inverter, mounting, wiring, possible battery), and labour. Installers often provide quotes that include all components and compliance documentation. According to pricing data from 2025: mid-range hybrid panel + inverter + battery kits with installation are being offered at competitive rates.
Because solar‑system needs vary (household size, energy usage, backup requirements), buyers should get a detailed, itemised quote rather than rely on fixed package prices. This ensures clarity on what’s included and whether compliance, quality, and warranty are genuinely part of the package.
What to Check Before Signing Up
- Certification and Compliance: Ensure the installer is listed among trusted, certified installers (membership in recognized associations, ability to issue compliance certificates, insurance coverage, etc.)
- Component Quality: Ask about panel brands, inverters, and other hardware. Reputable installers use Tier‑1 panels and certified inverters.
- Transparency in Quote: Insist on a fully detailed quote that breaks down costs: panels, labour, permits/COC, batteries (if any), wiring, monitoring, and after‑sales support.
- After‑Sales Support & Warranty: Confirm warranties on both equipment and workmanship, and that the installer provides maintenance or support if issues arise.
- References & Past Projects: Ask for previous client contacts or documented installations, installations similar to yours in scale and location.

Where to Buy Solar Panels or Kits
If you prefer to procure hardware yourself (for DIY installation with certified electrician, or to negotiate with installers), you can source panels and kits from distributors like Central Solar Supplies, which serve both retailers and installers nationwide.
Also, many of the recommended installers act as full‑service providers: they supply components, perform installation, handle compliance paperwork, and offer after‑sales support. This simplifies the process and reduces risk.
Installing solar power in South Africa can offer savings, energy independence, and reliability but only if you work with reliable, certified solar installers. Focus on companies that provide certification, transparent pricing, reliable hardware, proper documentation, and after‑sales support.
Start with verified names like Affordable Power Solutions and Alumo Energy, or suppliers such as Central Solar Supplies for hardware procurement.
Always demand a detailed quote, check compliance credentials, and confirm quality of components. By doing so, you maximize the chances of a smooth, compliant, long‑lasting solar installation for your home or business.
