The Renesola RS5-515~535N-E2 series is based around N-type cells in a half-cut configuration, which translates to stable performance under typical Polish conditions - with variable sunlight, low temperatures, and intermittent shading. These are monocrystalline modules that focus on real energy yield, rather than just specifications - they help minimize losses due to heating and maintain efficiency better on cooler days.

In practice, the RS5 N-E2 solves two common problems for installers and investors: the need for high power from a single module and predictable production over the long term. Its key features include a long power warranty and a robust design for reliability, which is important in projects where the cost of energy over the entire lifecycle is a key factor.

It is a good choice for commercial installations and solar farms, as well as for larger industrial rooftops, where high power density, resistance to weather conditions, and assured performance are crucial.

What owners get
Leading efficiency in class

Efficiency up to 22.76% exceeds comparable 535 Wp modules - Resun Solar RS8H-M-DG/BD (22.53%) and Hanersun Hitouch 5 HN18-72H (20.71%). This gives a real power-density advantage per m² of roof.

N-type half-cut cell design

The half-cut layout built on N-type cells reduces resistive losses and improves performance under partial shading and lower irradiance - relevant for variable weather conditions typical in Poland.

30-year linear power warranty

A 30-year power warranty places the RS5 N-E2 series at the top of the N-type segment - longer than the standard 25 years offered by many PERC modules, reducing risk for LCOE-driven project economics.

Long-established Tier-1 manufacturer

Renesola has operated since 2005 and holds Tier-1 bankable status, easing financing for commercial and utility-scale PV projects through financial institutions.

High per-module power output

The 515-535 Wp power range matches the upper end of comparable 535 Wp panels from Resun Solar and Hanersun, requiring fewer modules to reach a given installed capacity.

Trade-offs
No bifacial variant available

The RS5-515~535N-E2 series is mono-facial (is_bifacial: false), forgoing the typical 5-10% additional yield bifacial modules provide in ground-mount farm installations - the very segment this series targets.

15-year product warranty trails market leaders

The 15-year product warranty is shorter than the 25-year product warranties now offered by some N-type leaders (e.g., Tiger Neo, Vertex N series), even though the power warranty itself remains at 30 years.

Common questions

6 answered
What is the warranty on the Renesola RS5-515~535N-E2 panels?
Renesola provides a 15-year product warranty and a 30-year linear power warranty for the RS5-515~535N-E2 series. This means the manufacturer guarantees a defined output level for three decades — a key factor when calculating LCOE over the full system lifetime and when securing commercial project financing.
How do the N-type cells in the RS5-515~535N-E2 differ from standard PERC cells?
The N-type cells used in the RS5-515~535N-E2 series have a lower temperature coefficient, resulting in less power loss when the module heats up. They are also significantly less susceptible to PID and LID degradation than PERC cells. In practice, this translates to a higher annual energy yield at the same rated wattage, especially in installations with long daily operating hours.
Do the Renesola RS5-515~535N-E2 panels perform well in winter and under variable irradiance?
Yes. The N-type cell technology allows the RS5-515~535N-E2 to maintain high efficiency at low temperatures — the favorable temperature coefficient works to the module's advantage during cooler months. The half-cut cell layout also limits losses under partial shading, which matters in climates with frequent diffuse and patchy cloud cover.
Is the RS5-515~535N-E2 series suitable for solar farms and industrial rooftops?
Yes. At up to 535 Wp per module, the RS5-515~535N-E2 is designed primarily for commercial and utility-scale PV installations. High per-module wattage means fewer panels for the same system capacity, reducing BoS costs — wiring, racking, and labor. The 30-year power warranty ensures predictable generation throughout the project's entire financing period.
Are the Renesola RS5-515~535N-E2 panels bifacial?
No. The RS5-515~535N-E2 series is a mono-facial module — it collects light only from the front side. If you need bifacial Renesola modules that also harvest reflected albedo light from the ground, look for models with 'NBG' in the series designation, such as the RS5J-NBG or RS6-NBG lines.
Is Renesola a reliable manufacturer and is the RS5-515~535N-E2 still available?
Renesola is classified as a Tier 1 manufacturer by Bloomberg NEF, confirming proven financial and manufacturing capability. The RS5-515~535N-E2 series is active and currently available. When purchasing, verify that the supplier provides genuine modules with full warranty documentation and IEC certification to ensure long-term performance guarantees are honored.
