What are solar panels and how are they classified?
The solar panels convert radiation into electricity through photovoltaic cells. In this collection we group the most commonly used families: monocrystalline (high performance and smaller area per kW), polycrystalline (12 V/24 V formats and small size, useful in caravans and telecom), and bifacial (capture on both sides, ideal for ground or roofs with reflection). For volume purchases, you have packs and pallets with the same quality standard and warranty.
Advantages
- High efficiency: high unit power and better space utilization.
- Durability: certified materials, product warranty, and long-term linear power warranty.
- Mounting flexibility: compatible with coplanar, tilted, or ground structures.
- Scalability: from small installations to commercial plants with pallets.
Limitations
- Actual performance depends on orientation, shading, temperature, and system losses.
- Bifacial modules require an environment with reflectance to take advantage of their rear-side benefit.
- Electrical compatibility (Voc/IsC) must match the MPPT and inverter; size strings with thermal margin.
Applications
- Residential and community self-consumption on rooftops.
- Commercial/industrial in warehouses, canopies, or ground-mounted.
- Off-grid, caravans, and marine with 12 V/24 V formats (see compact polycrystalline).
- High-performance projects with bifacial and ground-mounted structures.
How to choose the right panel
- Technology: Mono for maximum efficiency per m²; bifacial if there is albedo; poly 12 V/24 V for small systems.
- Power and format: select dimensions and Wp compatible with your surface and structure.
- Electrical parameters: Voc, Vmp, Isc, and Imp must fit the MPPT window and inverter limits.
- Warranties: prioritize product warranties (years) and linear power (80–90% at 25–30 years depending on model).
- Quantity: for volume, consider packs/pallets for logistics and price per W.
Typical (indicative) specifications
| Technologies | Monocrystalline PERC / N-Type, Bifacial double glass, Poly 12 V/24 V |
| Power range | From ~100 W (compact) to >700 W (utility/commercial) |
| Module efficiency | ~20–23% in mono; bifacial with additional rear-side gain |
| Open-circuit voltage (Voc) | Check datasheet; size strings for minimum temperature |
| Short-circuit current (Isc) | See datasheet; check MPPT input limits |
| Warranties | Product and linear power (see manufacturer's conditions) |
| Certifications | IEC 61215/61730, mechanical strength and PID according to model |
Exact values vary by model. Always check the technical datasheet for string and protection calculations.
Best practices
- Calculate strings by Voc at minimum temperature and by Vmp in operation; respect the MPPT margin.
- Avoid partial shading; if unavoidable, use optimizers per module or for critical strings.
- Use certified structures and fasteners; torque and grounding as per manual.
- DC protections: isolator, fuses/fuse holders, and type II SPD at PV input when applicable.
Quick comparisons
- Monocrystalline: best performance per surface area and uniform aesthetics; ideal for limited roof space.
- Polycrystalline: 12 V/24 V formats for standalone systems, caravans, or marine use.
- Bifacial: rear-side gain with albedo (light gravel, white ground, or elevated structure); recommended for ground installation.
- Packs/Pallets: optimize logistics and cost per W in medium/large projects.
Accessories and related collections
Complete the installation with Solar Optimizers to improve performance under shading/mismatch and with Solar Panel Accessories (cables, MC4 connectors, clamps, and mounting structure). These categories are integrated with Monocrystalline, Polycrystalline, and Bifacial modules to facilitate a coherent and safe design.
Explore the Solar Panels collection and choose the technology that best suits your surface, target power, and budget, combining it with optimizers and accessories to maximize system output and longevity.
