Frequently asked questions

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.

It depends on what you run and when. We start from your appliance list — power rating, hours of use, and whether use is during the day or at night — plus how long you want backup to last. From that we size the PV array, inverter and battery. We don't apply one standard size to every site.

Often yes, but these loads need care. Motors and compressors draw a surge when they start, and air-conditioners use a lot of energy over long hours. The inverter must handle the surge and the battery must cover the night-time use. We look at each of these loads specifically before recommending a system.

Usually, if it is planned for. Tell us about expected future loads at the start so we can choose an inverter and battery arrangement that leaves room to add capacity.

That is a design choice, not a fixed number. Backup time depends on battery capacity and on which loads are connected. We agree with you which loads are essential and how many hours — or days — of backup you need, then show the battery size and cost that go with it.

Solar output drops, so the battery has to carry more of the load. Options include a larger battery, a generator or grid connection that recharges the battery, and a plan for which loads to reduce during long cloudy spells. We explain these trade-offs when we design the system.

We choose the battery per project and explain the options, for example lithium iron phosphate (LiFePO4) versus lead-acid, and how they differ in usable capacity, lifespan, maintenance and cost. The specific brand and model are named in your proposal.

It shows where parts of the system are warmer than expected while it is operating — for example hot cells or hot spots on modules, heating patterns across part of a module, warm connectors, or unusual heating at protection devices. These are signs worth checking; the cause is then confirmed on site.

No. Thermal imaging detects temperature differences on surfaces it can see. Some faults do not produce heat at the time of inspection, and components inside enclosures or under modules may not be visible. Weather and system load also affect results. That is why our reports state the conditions and limitations, and recommend on-site checks for significant findings.

On a day with steady, strong sunlight while the system is running normally, usually from late morning to early afternoon. If the weather turns cloudy or rainy we will reschedule rather than deliver unreliable images.

The report gives image evidence, locations and descriptions that you can share with your installer or the module manufacturer. Whether a claim is accepted depends on their warranty terms and their own assessment.

Most of the array is imaged from the air with a thermal drone, so roof access is often not needed for the survey itself. We do need safe access to the inverter and related equipment, and permission to fly at the site. The inverter and battery are checked on the ground with a handheld thermal camera.

No. The system has to be generating normally for the temperature differences to show, so you keep using power as usual.

Yes — houses, shop-lots, factories, warehouses and commercial buildings.

Our team operates the drone on site and checks the surroundings before take-off. For sites near restricted airspace, we check and apply for permission first.

We can quote for repairs separately based on the findings. You can also pass the report to your original installer to follow up.

Generally once a year. Do it sooner if output drops suddenly or after severe weather.

Send us your location, current power situation, a list of the equipment you want to run (with power ratings and hours of use if you have them), the backup time you want and photos of the installation area. WhatsApp or the enquiry form both work. For inspections, tell us the system size, roof or ground mounting, number of modules and any issues you have noticed.

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).

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.

Any site visit or assessment fee is confirmed with you before a visit is arranged.

For our off-grid packages: panels 12 years, battery 7 years, inverter 2 years (a 5-year inverter warranty is available at a different price — ask us), and mounting & wiring 5 years. For other systems, warranties follow each manufacturer's terms and are listed in your proposal.

Contact us by WhatsApp or phone, describe what is happening and send photos or screenshots of any error codes or monitoring data. We review remotely first and arrange a site visit if needed.

Yes for thermal inspection — we inspect PV systems regardless of who installed them. For repairs based on the findings, we can quote separately, or you can pass the report to your original installer to follow up.
