No grid?Life goes on.

Off-grid solar for farms, rural homes, work sites and islands — sized to the appliances you actually run, not one panel more.

Can you spot what needs checking?

Same roof, same moment. Drag the handle — or use the buttons — to compare the normal photo with the thermal image.

Looks normal in the photo — but the thermal image shows a small, sharply defined warm spot here. Worth checking on site.

A thermal image shows where — not why. The cause is confirmed with an on-site check.

02How much backup for rainy days?

The reserve is energy on top of one normal night. How fast the battery refills after a rainy spell needs a proper design.

Assumptions and formulas
  • Solar output: 3.2 kWh per kWp per day (Jomsolar's planning figure for Selangor), treated as panel output before inverter and battery losses.
  • Daytime use: PV → inverter at 95 %. Night use: charging 95 % × battery-to-socket 90 % (inverter included, counted once).
  • Battery (nominal): (night energy + reserve) ÷ (90 % usable × 90 %). The reserve adds battery, not panels.
  • Panels: counted by energy, 650 W each, rounded up — the wiring (strings, MPPT) is designed separately.
  • Inverter: everything switched on running at once × 1.25. Starting power of motors is not estimated.
  • Fridge: 1.2 kWh/day from a typical energy label, half by day and half at night. Aircon: 900 W at an average 60 % load.
  • A package is shown only if solar, battery, inverter, its daily-use reference and its aircon type all fit. No savings or payback are calculated.

Real projects

What we have built and checked

See all projects

Off-grid · Raub, Pahang

Solar for a hillside farm building

The difficulty
A farm building in a hillside valley that has to make its own power.
What we chose and why
An off-grid solar system on the building's own metal roof — the panels need no extra land.

Thermal inspection · Jenjarom, Selangor

Aerial thermal inspection of a shop-lot rooftop array

The difficulty
Rows of panels on a shop-lot roof that are hard to check one by one.
What we chose and why
One drone flight took thermal and normal photos of the whole array, compared panel by panel.
Result
One panel that looked normal had a small, sharply defined hot spot.

Flagged for an on-site check. The thermal image shows where — the cause is confirmed on site.

Off-grid · Pulau Lang Tengah, Terengganu

Rooftop solar for an island camp

The difficulty
An island camp: power has to be made on site, and transport and later servicing have to be planned.
What we chose and why
Off-grid solar on the roof of a beachside building — the camp has to make its own power on the island.

FAQ

Common questions

All questions
What is the difference between off-grid and hybrid solar?
An off-grid system runs without a utility connection: solar panels charge a battery bank, and an inverter supplies your appliances. A generator is often added as backup for long cloudy spells. A hybrid system also has solar and a battery, but works alongside the grid or a generator — the battery covers outages or selected loads, and the other source tops up when needed.
Do you have packages and prices?
Yes. There are eight off-grid packages from RM 13,990, each including panels, inverter, battery, delivery and installation — see the off-grid solar page. They are a starting point: we recalculate from your own appliance list, and the final system and price are confirmed after a site visit. Hybrid systems are quoted per site. Thermal inspections start from RM 799 for systems of 1–10 kWp (report and travel charged separately).
How much does a thermal inspection cost?
The on-site inspection is priced by system size: RM 799 for systems of 1–10 kWp, and RM 1,500 for systems above 10 kWp up to 20 kWp. Larger systems are quoted on request. The written report and travel are charged separately, and we quote the total before scheduling. Inspections are currently available in Selangor, Kuala Lumpur and Negeri Sembilan.
