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.
Design, installation, monitoring and maintenance are all part of the system.
You are not buying a box of panels and a battery. Every system below arrives engineered, installed, commissioned and monitored — and, if it connects to the grid, registered with the CEB or LECO.
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
For grid-connected systems, we submit the 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.
A battery in every package.
Selling surplus solar to the grid now earns less than buying electricity back from it, so every package from 3 kW to 20 kW includes battery storage. What your panels make during the day powers your evening, instead of being exported cheaply.
- Stores daytime surplus for the evening instead of exporting it
- Keeps your power on through a power cut
- Set up grid-connected or fully off-grid, depending on the property
- Battery sized to your usage after a site assessment
- Batteries carry a 5 to 10-year warranty, depending on the battery specified
- Large commercial systems (40 kW+) stay grid-tied and are designed to order
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.

Your inverter connects over WiFi or GPRS to a central dashboard, so the system’s performance is never a mystery.
- Daily, monthly and annual generation figures
- Live operational status and fault alarms
- Downloadable performance reports
- We monitor your system for the first year, provided the inverter is online
- Continued monitoring and panel cleaning available by agreement after year one
We guarantee 70% of the annual estimated generation for your system.
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.
