Solar Panels for Sale

A1 SolarStore carries solar panels from Canadian Solar, JA Solar, Jinko Solar, LONGi, Trina Solar, Q CELLS, REC, Axitec, Aptos Solar, and others, with prices starting at $150 per panel. The catalog includes standard 360W residential modules, high-output 750W commercial panels, and specialty formats like bifacial and all-black options. You can filter by wattage, brand, or cell technology and compare specs on one page.

How panels in this category differ

The main divider is wattage. Residential panels typically sit between 370W and 450W, while commercial modules go above 500W. Cell technology is the other variable: standard monocrystalline (PERC) panels are the most common and affordable; TOPCon and heterojunction (HJT) cells offer higher efficiency at a premium; bifacial panels generate power from both sides, which helps on ground mounts or light-colored roofs.

Price per watt also varies by brand. Panels from Canadian Solar or Trina Solar tend to run closer to $0.30/W, while modules from REC or Q CELLS can reach $0.60/W or more.

Matching panels to your project

Homeowners replacing an old roof or going solar for the first time usually start with 400W monocrystalline panels. They fit standard roof dimensions and offer a reasonable cost-to-output ratio. Contractors installing systems in HOA-regulated neighborhoods often pick all-black panels for a cleaner look.

For commercial ground-mount arrays or agricultural installations, bifacial or 550W modules make more sense because the extra yield per panel reduces racking and labor costs. Off-grid and RV setups tend to favor smaller, portable-friendly formats.

Specs that matter when buying solar panels

• Wattage (W): The power output under standard test conditions. Higher wattage means fewer panels for the same system size, which saves on racking and labor.
• Cell type: Monocrystalline PERC is the industry standard. TOPCon and HJT cells convert more sunlight to electricity but cost more. Bifacial panels also capture reflected light on the back side.
• Efficiency (%): The share of sunlight converted to electricity. Most panels fall between 20% and 23%. Higher efficiency matters when roof space is limited.
• Temperature coefficient: How much output drops per degree Celsius above 25°C. A lower number (closer to zero) means the panel holds up better in hot climates. Look for -0.30%/°C or better.
• Warranty: Most manufacturers offer a 25-year product warranty and a 25- to 30-year performance guarantee. Product warranty covers defects; performance warranty guarantees minimum output over time.
