How to Choose Solar Panels
Start with your available roof or ground area and work backward from your annual kWh target. Monocrystalline N-type and TOPCon modules deliver the highest efficiency per square foot, while bifacial panels add rear-side gain on ground mounts and light-colored roofs. Check the temperature coefficient if you install in hot climates — every 0.1%/°C matters on a dark roof in August. For most residential projects, 400–450W all-black modules balance aesthetics, output, and price per watt.
Pro Tips
- Match panel wattage to inverter DC/AC ratio — 1.2 to 1.35 is typical
- Bifacial shines on ground mounts and tilted flat roofs
- Compare $/W at pallet quantities, not single-panel retail
Solar Panels — Frequently Asked Questions
What wattage solar panel do I need?
Most homes land on 400–450W modules — the best balance of roof space, racking cost, and $/W. Divide your annual kWh target by your local sun-hours to size the array, then pick the wattage that fits the layout.
Are bifacial panels worth it?
On ground mounts and light-colored or flat roofs, bifacial gain of 5–20% is realistic. Flush-mounted on dark shingles the gain is minimal — standard mono is the better value there.
Do you sell panels by the pallet?
Yes — pallet and truckload pricing is our core business. Pallets typically hold 31–36 panels. Request a volume quote for tiered $/W pricing with freight included.
Which brands are Tier 1?
Silfab, Canadian Solar, JA Solar, REC, Trina, LONGi, and Qcells all carry BloombergNEF Tier 1 bankability status, backed by 25–30 year performance warranties.

Frequently Asked Questions
What wattage solar panel should I buy?
Match wattage class to the project. Budget builds, RVs, and off-grid: 300-399W. Standard residential rooftops: 400-459W (the industry sweet spot). Premium residential and small commercial: 460-549W. Ground mounts and commercial roofs: 550-709W. The right answer maximizes watts per square foot of usable mounting area, not watts per panel.
Monocrystalline, bifacial, TOPCon — what's the difference?
Monocrystalline PERC is today's value standard at ~21% efficiency. TOPCon N-type adds efficiency and degrades more slowly (about 0.4%/year vs 0.55%). Bifacial glass-glass modules harvest reflected light on the rear side for 5-15% extra yield on ground mounts — but gain almost nothing on a flush rooftop. Buy TOPCon for the warranty curve, bifacial for ground mounts, PERC for the price.
How do solar panels ship?
Single panels and small lots ship by the most economical carrier for their size; pallet quantities (typically 31-36 panels) ship LTL freight with curbside delivery. Panels are glass — we palletize and corner-protect every shipment, and we recommend inspecting at delivery and noting any damage on the freight receipt before signing.
What warranty do solar panels carry?
Two warranties matter: product (defects) and performance (output). Product warranties run 12-25 years depending on brand — Silfab and REC sit at the long end. Performance warranties are linear 25-30 year guarantees, typically promising 84-87% of rated output at the end of term on N-type modules.
Do I need permits or utility approval to install panels?
Grid-tied systems require a building/electrical permit from your AHJ and an interconnection agreement with your utility before energizing — plan on both. Off-grid systems generally skip the utility but still need electrical permits in most jurisdictions. Panels themselves carry the UL 61730 listing inspectors look for.
Is pallet pricing worth it if I don't need 30+ panels?
Usually, yes — pallet per-panel pricing plus one freight charge often beats small-quantity pricing plus parcel shipping, and spare panels are cheap insurance against breakage or future expansion. Contractors buying for multiple jobs should ask about multi-pallet and truckload quotes.
