Residential Solar

Solar designed around how your home uses energy.

Alpharex designs and installs residential solar PV systems — hybrid, on-grid and off-grid — to lower your electricity bill. There is no one-size-fits-all system: your consumption, backup requirements, property, and priorities determine the right configuration for your home.

Residential solar service area: Metro Manila (NCR); Rizal, Cavite, Laguna, Batangas and Quezon in South Luzon; and Bulacan, Pampanga, Tarlac, Nueva Ecija, Bataan and Zambales in Central Luzon.

02

On-Grid Solar

Focus on energy savings.

Works together with the utility grid and is designed primarily to reduce the electricity your home purchases from the grid.

Solar + Grid
03

Off-Grid Solar

Power beyond the grid.

Designed for properties where grid electricity is unavailable, unreliable, or where greater energy independence is required.

Solar + Battery + Independent Supply
