Solar Panel Technologies Used in 2026
The technologies represented in these companies' product portfolios differ in how photovoltaic cells collect charge, reduce electrical losses, and convert sunlight into usable power.
N-Type TOPCon
TOPCon uses a thin tunnel oxide layer and passivated contacts to reduce recombination losses.
It is used in N-type crystalline silicon products from manufacturers including JinkoSolar, Trina Solar, Astronergy, and Canadian Solar.
For product comparisons, module efficiency, temperature coefficients, dimensions, and degradation specifications provide more useful information than the TOPCon designation alone.
Back-Contact Solar Cells
Back-contact designs place electrical contacts on the rear side of the cell, reducing shading caused by front-side metallization.
LONGi's HPBC technology is one example.
Back-contact architecture and contact passivation describe different design characteristics. They are not necessarily mutually exclusive.
Heterojunction Solar Cells
HJT combines crystalline silicon with thin semiconductor layers that form passivated junctions.
Canadian Solar's HiHero modules use this technology.
The practical comparison with TOPCon or other crystalline silicon products should consider actual module efficiency, temperature coefficients, degradation specifications, and cost under the intended operating conditions.
CdTe Thin-Film Modules
CdTe modules use deposited semiconductor layers instead of crystalline silicon wafers.
First Solar manufactures CdTe modules for utility-scale applications.
Because module construction and electrical characteristics differ from crystalline silicon products, project evaluation should include system configuration, expected energy production, and balance-of-system costs.
Bifacial and Glass-Glass Modules
Bifacial modules can generate electricity from light reaching both sides of the photovoltaic cells.
Rear-side energy production depends on ground reflectivity, mounting height, row spacing, and shading. A manufacturer's stated bifacial characteristics do not establish a fixed energy gain for every project.
Glass-glass refers to a module laminate using glass on both sides. It describes construction rather than whether the cells can generate electricity from rear-side illumination.
How to Choose a Solar Panel Company for Your Project
The appropriate supplier depends on the module's electrical characteristics, physical dimensions, certifications, warranty responsibilities, and availability for the intended project.
Compare Module Power and Efficiency
Solar module power is commonly rated under standard test conditions (STC), which specify 1,000 W/m² irradiance, a cell temperature of 25°C, and an AM1.5 reference spectrum.
Rated power and module efficiency describe different characteristics.
A 700 W module can produce more power than a 500 W module simply because it has a larger surface area. Higher wattage alone does not establish higher conversion efficiency.
For space-constrained rooftops, compare module efficiency and usable installation area. For larger projects, evaluate module dimensions alongside mounting geometry, electrical design, and expected energy yield.
Check Electrical Compatibility
The electrical parameters in a module datasheet determine its compatibility with the planned photovoltaic system.
Important values include:
Pmax: Maximum power under specified test conditions.
Voc: Open-circuit voltage.
Isc: Short-circuit current.
Vmp: Voltage at maximum power.
Imp: Current at maximum power.
Temperature coefficients: Changes in electrical characteristics as cell temperature varies.
Maximum system voltage: The applicable voltage limit for the module.
Designers should calculate maximum string open-circuit voltage using the module's Voc temperature coefficient and the site's minimum design temperature.
The result must remain within the voltage limits of the inverter and other system components.
Operating current must also be checked against inverter inputs, connectors, cables, and protective equipment. High-current modules can require different string and equipment configurations even when their rated power is similar.
Review Dimensions and Mechanical Requirements
Module length, width, weight, frame construction, and permitted mounting zones affect transport, installation, and structural design.
For rooftop projects, the mounting system must be evaluated against roof capacity, support spacing, wind exposure, and snow loading where applicable.
Mechanical load test ratings do not automatically establish allowable project design loads. The manufacturer's installation instructions and applicable structural requirements determine how those ratings can be used.
Verify Certifications and Product Documentation
IEC 61215 addresses photovoltaic module design qualification, while IEC 61730 addresses module safety qualification.
Additional approvals may apply depending on the destination market and project requirements.
Before procurement, confirm that the available documents cover the exact module model and configuration.
Relevant documents include:
Product datasheets and installation manuals.
Applicable certification and test records.
Product and performance warranty statements.
Manufacturing and traceability information where required.
Packaging and handling instructions.
Certification for one model should not be assumed to cover every module in the same product family.
Review Warranty Responsibilities and Supplier Support
Product warranties generally address specified defects, while performance warranties describe commitments concerning module power output over time.
The warranty period should be evaluated together with exclusions, claim procedures, and responsibility for replacement, transportation, and labor costs.
When a distributor sells modules manufactured by another company, buyers should identify the legal entity providing the warranty and the party responsible for technical claims.
This distinction is especially important for long-term commercial projects where ownership or service arrangements may change during the operating life of the system.
Evaluate Supply and Project Requirements
Before ordering, confirm the exact module model, available quantity, delivery schedule, destination-market documentation, and technical support arrangements.
Project requirements also affect module selection:
Residential rooftops: Usable roof area, module dimensions, structural compatibility, and installation access.
Commercial and industrial rooftops: Roof loading, electrical design, maintenance access, and installation scheduling.
Utility-scale projects: Energy yield modeling, mounting systems, electrical architecture, logistics, and lifetime project costs.
Solar-plus-storage projects: Compatibility among photovoltaic modules, inverters, batteries, energy management systems, and charging equipment where applicable.
These requirements help determine whether a technically suitable module can also be delivered and installed under the project's commercial and operational constraints.
