LONGI 550WP Mono PERC: High power and Cell technology Cells for maximum performance

The search for maximum profitability in commercial, agricultural or residential solar installations of great consumption requires That optimize the space available on the deck. The photovoltaic panel LONGI LR5-72HPH-550M G2 of 550wp Respond to this need with an advanced monocrystalline silicon architecture, designed specifically to generate more kilowatts-hour per square meter and reduce the amortized cost of energy (LCOE).

Mitigation of shading and resistance against degradation (Low Lid)

On Tienda Solar We prioritize components with technologies that ensure long-term constant production. This module stands out for its system of 144 Cells (72 cut symmetrically), which reduces the length of the busbars and decreases the internal resistance of the passage of the current. In the presence of partial shadows (produced by chimneys, clouds or dirt), only the affected half of the panel decreases its performance, allowing the remaining section to continue generating energy in a normal way.

In addition, Longi implements in his silicon wafers a process of gallium dock. This innovation effectively combats light-induced degradation (Low Lid), ensuring that the loss of power the first year is minimal and protecting the panel against the pid degradation phenomenon (Power Induced Degradation) Provided by voltage differences in serial-connected strings up to 1500V.

Mechanical robustness and certified durability

Longi 550WP chassis is built with an anodized silver color aluminum frame and a high transparency tempered glass front face, capable of resisting severe hail impacts and supporting high mechanical pressure loads: up to 5400 pa Static of snow and 2400 PA wind dynamic cargo. Your Certification Sleeca Connection Box Ip68 Incorporates 3 bypass diodes to shield the circuit and avoid the formation of micro-cracks or hot spots (hot-spot), protecting the useful life of the system and being backed by a guarantee of 10-year-old materials and 25 years of linear production.

Frequently Asked Questions (FAQ)

1. What real advantages does cell technology offer items in this 550W panel? By dividing the cells in half, the electric current circulating for each busbar It is reduced by half. Since the energy losses are proportional to the square of the current, this design minimizes internal losses by heating, improves the temperature coefficient and maintains optimal production when the module receives partial shadows in its lower or higher half.
2. For what kind of solar installations is the LONGI 550WP model? Due to its dimensions (2.27 meters long) and its high weight of 32.6 kg, it is a module recommended especially for solar solar installations, medium and large industrial covers, or residential structures where mechanical fixings and mechanical fixings are available. Robust of great format.
3. What does it mean to have a positive power tolerance (0 / + 5W)? This guarantees that the solar panel you receive at your home will have, at least, the nominal power of 550W specified in the Technical Sheet, can come up to 555W under standard laboratory conditions (STC). You will never receive a panel with a power lower than the contracted.
4. What warranty coverage does the Longi manufacturer offer in this range? Longi Solar, a consistently qualified as a global Tier 1 manufacturer, offers a 10-year structural guarantee that covers manufacturing defects, materials and labor, together with a guarantee of linear performance that ensures that the panel will retain the level of optimal production after 25 years of operation Continuous.
