About Alpha Solar
Alpha Solar Sdn Bhd is a residential-focused solar company headquartered in Shah Alam, Selangor, with additional offices in Johor Bahru, Bukit Mertajam (Penang) and Kuantan, Pahang. It says it specialises in residential solar panel systems, though it also describes serving commercial and industrial customers. Its project gallery lists residential installations dated from 2016 to 2024.
The company doesn't name specific panel or inverter brands. It says its solar panels and inverters are "backed by competitive warranties" and describes an ongoing research and development effort to improve its technology, though no specific figures or completed-project counts are published to support these claims.
Enquiries are handled by phone, WhatsApp and email, and the site outlines an installation process covering system sizing, a site survey, and handling government permits and Net Energy Metering (NEM) applications on the customer's behalf. It also offers an ongoing maintenance service, including checks for issues such as hot spots and micro-cracks, and runs a referral programme called Refer4Cash.
