South Africa’s rising electricity tariffs and ongoing loadshedding have made solar energy one of the fastest-growing investments for households and businesses. By 2025, the cost of solar systems has come down significantly, while financing options and government incentives have improved. For many South Africans, solar is no longer a luxury—it’s becoming a necessity.
In this guide, we explore the best solar panel deals in South Africa in 2025, compare providers, outline financing options, and highlight what to consider before buying.
Why Solar Panels Are in High Demand
There are three major reasons why solar adoption has surged in 2025:
- Loadshedding – Rolling blackouts continue to affect productivity, study time, and quality of life. Solar panels with battery storage provide reliable backup power.
- Rising electricity costs – Eskom tariffs have increased annually, making solar a cost-effective long-term investment.
- Falling solar costs – Globally, solar panel prices have dropped by more than 80% in the past decade, making systems more accessible.
What to Look for in a Solar Panel Deal
Before we review the best deals, here are key things to consider:
- Panel Efficiency: Most panels range from 18% to 23% efficiency. Higher efficiency = more power per m².
- System Size: Choose based on household needs. A 3–5kW system powers small-to-medium homes; 8–10kW suits large households.
- Warranty: Good panels carry 20–25 year performance warranties.
- Battery Storage: Lithium-ion batteries (5–10kWh) extend independence from Eskom.
- Inverter Quality: Hybrid inverters allow grid-tied and off-grid operation.
- Accreditation: Installers should be registered with the South African Photovoltaic Industry Association (SAPVIA) and have CoC (Certificate of Compliance).
- Financing: Some banks and retailers offer financing from as little as R699/month.
