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.

Cell type	Efficiency range	Best for
Monocrystalline PERC	20-21%	Residential rooftops, budget-friendly systems
TOPCon / HJT	21-23%	Space-constrained roofs, maximum output per panel
Bifacial	20-22% (front side)	Ground mounts, carports, light-colored surfaces

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.

Buying solar panels from A1 SolarStore

A1 SolarStore offers panels from over 50 manufacturers, so you can compare options across price points and technologies in one place. Local pickup is available, and we ship across the US with freight quotes provided at checkout. All panels are covered by the manufacturer warranty listed on each product page.

FAQ

How much do solar panels cost?

Prices depend on wattage, cell technology, and brand. At A1 SolarStore, panels start at $150 per unit. A typical 400W residential panel runs between $150 and $300. Per-watt pricing ranges from roughly $0.25 to $0.70, with premium high-efficiency models at the upper end. The total cost for a home system (panels only, no installation) usually falls between $3,000 and $8,000 depending on system size.

Are solar panels worth it?

For most homeowners, yes. A residential system typically pays for itself in 6 to 10 years through electricity savings, and panels last 25 to 30 years. The federal solar tax credit (30% through 2032) reduces the upfront cost. Home values tend to increase too. Studies from Zillow and Lawrence Berkeley National Laboratory found that homes with solar sell for a premium.

How long do solar panels last?

Most panels are rated to produce electricity for 25 to 30 years, and many continue beyond that at reduced output. Performance warranties guarantee at least 80-87% of original output after 25 years. Panels have no moving parts, so mechanical failure is rare. Inverters and other balance-of-system components typically need replacement before the panels do.

How many solar panels do I need?

It depends on your electricity use and the panel wattage you choose. A typical US household consumes about 10,500 kWh per year. With 400W panels and average sun exposure (4-5 peak sun hours per day), that works out to roughly 20-25 panels. Your number will vary based on roof orientation, shading, local climate, and how much of your electric bill you want to offset.

Where can I buy solar panels for sale online?

A1 SolarStore has solar panels for sale from over 50 brands. You can filter by wattage, cell type, price, and manufacturer, compare specs side by side, and order directly for shipping or local pickup. All panels ship with full manufacturer warranty documentation.
