Solar Products, Equipment Supply and Technical Specification
As a solar products supplier, Trivonix sells specification before it sells hardware. Almost every component in a solar plant is available at three price points from a dozen vendors, and the datasheet headline — module efficiency, inverter peak efficiency, structure grade — is rarely the number that determines how the plant performs in year twelve.
We supply modules, inverters, mounting systems, cables, combiner boxes, protection devices and monitoring hardware, and we tell clients plainly which specifications matter on their site and which are marketing.
What this service covers
- Specified against site conditions
- Coastal, high-ambient, dusty and high-humidity sites need different equipment. The specification reflects that.
- Full balance of system
- The failure points in a solar plant are rarely the modules. Cables, connectors, SPDs and enclosures are specified with the same rigour.
- Documentation on delivery
- Test certificates, warranty terms and compliance documentation supplied with the equipment, not chased afterwards.
Solar modules
Module choice is usually presented as a wattage and an efficiency figure. Those matter mainly when area is constrained. On most projects, three less-discussed parameters have a larger effect on lifetime output.
- Temperature coefficient — how much power the module loses per degree above 25°C. On a hot site this eclipses a point of nameplate efficiency.
- Degradation warranty — first-year degradation and the annual rate thereafter, which compound over twenty-five years.
- Low-irradiance performance, which governs output during early mornings, late afternoons and overcast conditions.
- Cell technology and bifaciality, relevant where ground albedo or mounting height can be exploited.
- Certification to the applicable IEC standards for design qualification and safety, plus any additional testing appropriate to the site environment.
Inverters
The inverter is the component most likely to need replacing within the plant's life, and the one that most directly determines how much of the DC generation reaches the meter.
String inverters
Multiple MPPT inputs, distributed failure risk, easier replacement, and better tolerance of fragmented or multi-orientation arrays. Generally the right answer for rooftops and segmented sites.
Central inverters
Lower cost per kW at scale and simpler cabling topology, at the cost of concentrated failure risk and less granular MPPT. Generally suited to large uniform ground-mounted arrays.
What to check beyond peak efficiency
European weighted efficiency, MPPT voltage window against your string design, night-time consumption, IP rating and cooling method, grid support functions required by the local utility, and the monitoring and communication protocols supported.
Mounting structures
The mounting system carries the array for its entire life under wind, snow where applicable, thermal cycling and corrosion. It is also the component most frequently value-engineered down to the point of failure.
- Material and coating — hot-dip galvanised steel, pre-galvanised sections or aluminium, selected against the site's corrosivity category.
- Structural design verified for the site's actual wind zone, terrain category, height and exposure — not a generic load case.
- Fastener grade and, on coastal sites, stainless specification appropriate to the chloride environment.
- Thermal expansion allowance across long rail runs.
- Compatibility with the module frame, including clamping zones permitted by the module manufacturer's warranty.
Balance of system and protection
Balance of system is where cheap procurement is punished. DC connectors, cable insulation and surge protection devices operate under UV, heat and voltage stress for decades in outdoor conditions.
- Solar DC cable rated for UV exposure, high temperature and the system's maximum voltage, with the correct conductor cross-section for the run length.
- DC connectors used as matched pairs from the same manufacturer — mixed-brand mating is a well-documented cause of hot spots and fires.
- Combiner boxes, DCDB and ACDB with correctly rated fuses, isolators and enclosure IP ratings.
- Surge protection devices on both DC and AC sides, coordinated with the earthing and lightning protection design.
- Monitoring hardware, energy meters and communication gateways compatible with the platform the client will actually use.
How we specify and supply
Equipment supply is only as good as the specification behind it. Our process is deliberately unglamorous: understand the site, write a technical specification, evaluate vendors against it, and supply against documented compliance.
Clients buying equipment for a project we are not building still get the same specification discipline. If a proposed component is wrong for the site, we say so before the purchase order rather than after commissioning.
Frequently asked questions
Which solar panel specification actually matters most?
For most sites, the temperature coefficient and the degradation warranty matter more than nameplate efficiency. Efficiency governs how much power you get per square metre, which only binds when area is limited. Temperature coefficient governs how much you lose on every hot afternoon, and degradation governs what you still have in year twenty.
Should I choose string inverters or a central inverter?
String inverters suit rooftops, fragmented arrays and multi-orientation layouts, and they contain the impact of a single failure. Central inverters cost less per kW on large, uniform ground-mounted arrays but concentrate risk. The array geometry usually makes the decision before cost does.
Can I supply my own equipment and have you install it?
Yes, with one condition: we review the specification first. If we are commissioning and standing behind the system, the components have to be suitable for the site and compatible with each other. Where something is unsuitable we will explain why and propose an alternative.
Why does mixing DC connector brands matter?
Connectors from different manufacturers may mate physically while making poor electrical contact, because contact geometry and spring tension are not standardised across brands. The result is elevated resistance at the joint, heating under load, and a well-documented fire risk. Matched pairs from one manufacturer are the only safe practice.
What documentation should come with solar equipment?
Datasheets, applicable IEC or equivalent test certificates, warranty terms in writing with the claim process stated, installation manuals, and — for modules — flash test data for the delivered batch. If a supplier is reluctant to provide these before purchase, that is itself useful information.
