The final solar panel price you’re quoted comes down to a combination of technical and logistical factors. The most common price drivers include:

• System size in kilowatts – directly proportional to cost
• Battery type and capacity – lithium batteries add value but increase the upfront price meaningfully
• Inverter specification – hybrid inverters cost more but are essential for load shedding protection
• Roof access and complexity – steeper or more complex roofs take longer to install on
• Installer and region – Cape Town and broader Western Cape pricing varies between suppliers

The golden rule when comparing solar panel quotes is to ensure you’re comparing the same specifications across every quote, brand, wattage, warranty, and battery capacity included. For more information Explore Cape Decking’s solar options or Read more in our Solar Panels blog
