Overview

Made with SunPower’s highest-efficiency Maxeon® solar cells, these portable solar panels deliver the most power and highest charging capacity in their product class. Manufactured using a top-grade, lightweight polymer material, allowing for easy transport, installation, and flexibility up to 30 degrees. They come with Tyco (PV4-S) (MC4 compatible) male and female connectors on 450mm long cables. SPR-E-Flex-50 Weight 1.1 kg Panel Dimensions 653 x 556 x 20 mm with Jbox, (2 mm w/o Jbox) Designed in the USA. Assembled in Philippines. SPR-E-Flex-100 Weight 2.0 kg Panel Dimensions 1153 x 556 x 20mm mm with Jbox, (2 mm w/o Jbox) Designed in the USA. Assembled in France. Warranty: 2 years product warranty; 5 years limited power warranty of 80% of the minimum specified power rating. Designed for Toughness The SunPower Maxeon® Solar Cell is the only cell built on a solid copper foundation. Flexible panels made with SunPower cells are resistant to power loss via cracking and corrosion, unlike conventional cells, which are much more likely to lose power when bent or subjected to a moist environment. SunPower flexible panels are the Number1 choice for customers due of the combination of high power and cell ruggedness. Easy and Low Cost Installation The panel can be installed with adhesives and/or use of stainless steel grommets in the panel. The panels have standard quick-connect cables. An easy-to-follow installation guide is provided with each panel. Max. System Voltage: 45 V Series Fuse Rating: 15 A Power Temp Coeffiecient: –0.35%/° C Voltage Temp Coefficient: –58.9 mV/° C Current Temp Coefficient: 2.6 mA/° C Please Note: Because of the nature of the manufacturing process for flexible panels, some visual imperfections in the laminate are to be expected. These in no way affect the electrical performance of the product or their life.

Reading the specifications

SunPower® Flexible Solar Panels is listed with 1 published specification from Sunpower, including weight (kg) of 2. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a solar panel, the figures that matter most are temperature coefficient of power, usually −0.26 to −0.35 %/°C, first-year and annual degradation, and the performance warranty that guarantees them, physical dimensions and weight, which decide what fits your roof and mounting and open-circuit voltage (Voc) and short-circuit current (Isc) for string design. Panels are the generating half of the system and the part that determines how much energy is available at all. They are also the longest-lived component, routinely still producing over 80% of their original output after 25 years.

Before you buy a solar panel

The checks below apply to any solar panel. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Compare cost per watt rather than price per panel — a higher-wattage module is often cheaper per watt and needs fewer mounting rails, clamps and cable runs.
Prefer a lower (closer to zero) temperature coefficient in hot climates. Panels lose output as they heat up, and on a 45 °C roof the difference between −0.34 %/°C and −0.29 %/°C is real energy over a year.
Read both warranties. The product warranty (typically 12–15 years, up to 25 on premium modules) covers manufacturing defects; the separate performance warranty guarantees output — commonly 87–92% remaining at year 25.
Check the physical dimensions against your usable roof area before ordering. Modern modules are large, and a layout that works on paper can fail against obstructions, walkways and setback rules.

Where buyers lose money

Ignoring certification. IEC 61215 and IEC 61730 are the baseline; without them, warranty claims and grid approvals get complicated.
Buying the highest wattage available without checking the inverter's MPPT voltage window — a string that sits outside the window produces less, or nothing.
Assuming rated power is what you will see. Real-world output at midday is typically 75–85% of the nameplate figure after temperature, soiling, wiring and inverter losses.

Price and availability

SunPower® Flexible Solar Panels is listed at £ 65 (GBP). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Sunpower locally before ordering.

SunPower® Flexible Solar Panels — frequently asked questions

How much does SunPower® Flexible Solar Panels cost?

SunPower® Flexible Solar Panels is listed at £ 65 (GBP). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of SunPower® Flexible Solar Panels?

We hold 1 published specification for this solar panel, including weight (kg) 2. The full table is on this page, listed under model SPR-E-FLEX50.

Who makes SunPower® Flexible Solar Panels?

SunPower® Flexible Solar Panels is a Sunpower product, listed under solar panels with model reference SPR-E-FLEX50. The Sunpower brand page lists the rest of its range so you can compare across the catalogue.

Is SunPower® Flexible Solar Panels right for my system?

That depends on what it has to connect to. For a solar panel, check open-circuit voltage (Voc) and short-circuit current (Isc) for string design, rated power in watt-peak (Wp) measured at standard test conditions and module efficiency, typically 19–23% on current products against the rest of your equipment before price enters the decision. Keep every panel in a string identical in model and rating. Mismatched modules in one string pull the whole string down to the weakest one.

Where can I buy SunPower® Flexible Solar Panels?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
