Understanding Solar Panels
Discover the latest solar panel technologies and find the perfect match for your energy needs. We install high-efficiency panels from top tier-1 brands.
Latest Panel Technologies
Mono PERC
Monocrystalline PERC panels offer high efficiency and better performance in low-light conditions by adding a passivation layer to the rear of the cell.
TOPCon
Tunnel Oxide Passivated Contact (TOPCon) represents the next generation of N-type cells, providing higher efficiency and lower degradation rates than standard PERC.
Bifacial
Bifacial panels capture sunlight from both the front and rear sides, increasing overall energy generation by utilizing reflected light.
N-Type
N-Type solar cells have lower degradation (LID) and perform better at high temperatures, ensuring longer lifespan and sustained high output.
Half-cut Cells
By cutting cells in half, these panels reduce resistive losses, operate cooler, and offer better performance when partially shaded.
Important Metrics to Consider
Panel Efficiency
Modern Tier-1 panels offer efficiencies ranging from 21% to over 22.5%, meaning they convert more sunlight into usable electricity per square meter.
Warranty
Top brands provide a 10 to 12-year product warranty against manufacturing defects, and a 25 to 30-year linear performance warranty.
Degradation
High-quality panels degrade less over time. N-Type and TOPCon panels typically guarantee over 87% of their original output at year 25.
