Sharp Solar Panels: Complete Guide, Model Specifications & History

Last updated: March 2026

Sharp was one of the world’s largest solar panel manufacturers for decades — and millions of Sharp panels are still installed and operating worldwide today. Whether you’re looking up specs for an existing Sharp system, searching for replacement panels, or researching the history of one of solar’s pioneering companies, this guide covers everything.

Sharp Solar Panels: Company History (1959–2026)

Sharp Corporation was founded in 1912 as a metalworking shop by Tokuji Hayakawa in Tokyo. It became a major electronics manufacturer and was formally incorporated as Sharp Corporation in 1970, headquartered in Osaka, Japan.

Sharp’s solar history is particularly long — one of the oldest in the industry:

• 1959 — Sharp begins research into solar cells
• 1963 — Sharp begins mass production of solar cells — one of the earliest commercial solar manufacturers in the world
• 1976 — Sharp supplies solar panels to power Japanese lighthouses — an early landmark commercial application
• 2002 — Sharp establishes Sharp Electronics Corporation as its US subsidiary and enters the US solar market
• 2003 — Sharp opens its US solar panel assembly facility in Memphis, Tennessee, using monocrystalline and polycrystalline cells produced in Japan
• 2004 — Sharp opens a manufacturing facility in Wrexham, North Wales (UK), serving the European solar market
• 2006–2008 — Sharp is the world’s largest solar cell manufacturer by production volume
• 2012–2013 — Sharp begins withdrawing from consumer solar panel sales in Western markets as Chinese competition intensifies and Sharp faces financial difficulties
• 2016 — Taiwan’s Foxconn acquires a controlling stake in Sharp Corporation
• 2020s — Sharp continues solar manufacturing in Japan through Sharp Energy Solutions Corporation (SESJ), focusing primarily on the Japanese domestic market. Their Sakai City facility remains active.

Are Sharp Solar Panels Still Made?

Yes — but not for export to Western markets. Sharp Energy Solutions Corporation (a Sharp subsidiary) continues to manufacture solar panels in Japan for the Japanese residential and commercial market. They produce high-efficiency monocrystalline panels under the Sharp brand, but these are not widely sold or distributed in North America or Europe as of 2026.

If you have Sharp panels installed in North America or Europe, they were almost certainly manufactured between 2003 and 2013. These panels have a rated 25-year power output warranty, so systems installed in that period should still be under warranty coverage — though warranty claims against a company that no longer operates in your market are complicated (see the FAQ section below).

Sharp Solar Panel Model Specifications

The following table covers the major Sharp solar panel models sold in North America and Europe. These are the models most commonly found in installed systems today.

Sharp Monocrystalline Solar Panel Models

Sharp Polycrystalline Solar Panel Models

Note: All specifications are at Standard Test Conditions (STC): 1000 W/m² irradiance, 25°C cell temperature, AM1.5 spectrum. Actual field output will be lower.

Historical Price Data (2010–2013)

The following price table is preserved for historical reference — useful for insurance claims, system valuations, or research into early US solar market pricing. These prices reflect the 2010–2013 period when Sharp panels were actively distributed in North America.

How Do Sharp Solar Panels Perform After 10+ Years?

Sharp monocrystalline and polycrystalline panels from the 2005–2013 era are now 12–21 years old. Here’s what to expect from panels that age:

• Power degradation: Sharp’s warranty guaranteed output would not drop below 80% of rated power over 25 years — equivalent to roughly 0.7–0.8% annual degradation. Real-world studies of similar panels from this era show actual degradation often lower than warranted, typically 0.4–0.6% per year. A Sharp NT-175 installed in 2008 should still produce ~155–165W today.
• Cell micro-cracking: Panels from this era are more susceptible to micro-cracking from thermal cycling than modern panels with more robust cell interconnects. Micro-cracks don’t typically cause immediate failure but reduce output over time.
• Frame and junction box condition: Check for corrosion on the aluminum frame, delamination of the backsheet, and yellowing/browning of the EVA encapsulant. These are the failure modes to watch for in older panels.
• Connector condition: Older MC3 and MC4 connectors (depending on age) may need inspection — corroded connectors cause resistance losses and are a fire risk.

Sharp Solar Panel Replacement Options

If you need to add panels to an existing Sharp string system or replace failed panels, here are your options:

Option 1: Find Used Sharp Panels

Used Sharp panels appear regularly on eBay, Facebook Marketplace, and from solar salvage dealers. For adding to an existing string, matching the model (same Vmp and Imp) is important to avoid mismatch losses. Expect to pay $20–$80 per used Sharp panel depending on wattage and condition.

Option 2: Use a Modern Panel with Power Optimizers

If exact-match Sharp panels are unavailable, you can add modern panels with different specifications by using DC power optimizers (SolarEdge or Tigo) on both the old and new panels. Optimizers make each panel operate independently, eliminating mismatch losses between different panel models.

Option 3: Upgrade the Whole System

For systems where multiple Sharp panels have failed, it may make more economic sense to replace the entire array with modern 400–430W panels. A modern 10-panel system (4,200W) can replace a 24-panel Sharp system (175W × 24 = 4,200W) with far less roof space and a new 25-year warranty.

Where to Find Sharp Solar Panels For Sale

As of 2026, Sharp panels are no longer sold through mainstream US or European solar distributors. Sources for finding Sharp panels:

• eBay — Regularly lists used and refurbished Sharp panels; search by model number for best results
• Facebook Marketplace — Local listings often come from homeowners who removed their old systems during roof replacements
• Craigslist — Similar to Facebook Marketplace; best for local pickup of heavy panels
• Solar salvage dealers — Companies that buy decommissioned commercial solar arrays often have Sharp panels in quantity
• Solar panel recycling companies — May sell panels that are still functional before sending them to recycling

Frequently Asked Questions

What happened to Sharp solar panels?

Sharp gradually exited Western solar panel markets between 2012 and 2015 as Chinese manufacturers drove panel prices down sharply, making it unprofitable for Japanese manufacturers to compete on cost. Sharp faced broader financial difficulties and sold a controlling stake to Foxconn in 2016. The solar business continues in Japan under Sharp Energy Solutions Corporation, focused on the Japanese domestic market. Sharp panels are no longer sold through distribution in North America or Europe.

Are Sharp solar panels still good?

Yes — Sharp panels manufactured between 2003 and 2013 were high-quality products. The polycrystalline and monocrystalline panels from this era used good-quality silicon cells and robust construction. Most systems with Sharp panels that are still operating normally will continue to produce electricity for many more years. The technology was reliable; the company exit from Western markets was a business decision, not a quality issue.

Who makes Sharp solar panels now?

Sharp Energy Solutions Corporation (SESJ), a subsidiary of Sharp Corporation, manufactures solar panels for the Japanese market at their Sakai City, Osaka facility. These are not exported to North America or Europe in any significant volume as of 2026.

What is the efficiency of Sharp solar panels?

Sharp’s panels from the main production era (2005–2013) achieved 12–14.4% efficiency — typical for the technology of that time. For reference, modern monocrystalline PERC panels achieve 20–22% efficiency. The lower efficiency of older Sharp panels means they require more roof area to produce the same power as a modern system.

Can I claim warranty on my Sharp solar panels?

This is complicated. Sharp’s original product warranty covered defects; the performance warranty covered output degradation. Since Sharp no longer operates as a solar business in North America or Europe, warranty claims are difficult to pursue. Your best recourse for warranty issues is: (1) check if the installer who sold you the system provided their own workmanship warranty, (2) contact Sharp Corporation’s general customer service to understand if any warranty support exists, (3) consult a solar attorney if the failure represents significant financial loss. Many homeowners in this situation find that warranty claims against departed solar companies are not practically enforceable.
