Description

Overview

The JA Solar 620W Bifacial Mono Solar Panel is a high-efficiency JA Solar solar panel that turns South Africa’s abundant sunshine into free, clean electricity. Supplied and delivered nationwide by B&B Solar Power Solutions SA — from Johannesburg, Pretoria and Cape Town to Durban, Gqeberha and East London — with genuine, warrantied stock and expert sizing advice.

Every JA Solar 620W Bifacial Mono Solar Panel turns sunlight into electricity you no longer need to buy from Eskom, lowering your monthly bill as tariffs keep rising. The N-Type double glass design captures energy on both the front and rear surfaces, adding up to 25% more yield from reflected light.
Additionally, it suits homeowners, businesses, farms, and solar installers across South Africa who need high-output, long-lasting panels.
