Our systems

Solar built for
Sri Lankan roofs.

From a single family home to a warehouse rooftop, every Hasthimuni system is designed around your roof, your shading and your actual monthly usage — then installed and maintained by the same team.

Not add-ons — the package

Design, installation, monitoring and maintenance are all part of the system.

You are not buying a box of panels. Every system below arrives engineered, installed, commissioned, registered with the CEB or LECO, and monitored.

01 — Design

A free site assessment and energy audit, then a system sized to your roof and consumption.

02 — Installation

Typically about 10 days on site, installed and commissioned by our own team.

03 — Paperwork

We submit your net-meter application to the CEB or LECO as part of the job.

04 — Aftercare

One year of performance monitoring, with maintenance and cleaning available after that.

Off-grid & battery backup

Keep your power on.

  • Runs through a power cut instead of shutting down with the grid
  • Works on properties with a poor grid connection — or none at all
  • Built around energy independence, not selling units back
  • Sized to the property after a site assessment
What’s inside every system

You are buying a 25-year asset. The parts matter.

We do not substitute cheaper components to win a quote. This is what goes on your roof and into your switchboard, on every system we install.

Warranty.

Whichever package you choose, the cover is the same — a solar system is a 25-year asset, and it should be backed like one.
