Why choose solar panels now?

Homeowners aged 35–65 seek panels that cut electricity bills 50–90% via net metering while qualifying for federal incentives like the 30% tax credit. Triggers include spiking summer bills or neighbors' installations, prompting searches for "solar panels near me" or "best solar panels for home."

What do competitors overlook?

Sites like EnergySage and GoGreenSolar provide quotes and basics but skip brand-specific fits for U.S. roofs, pallet logistics, and clearance deals on high-wattage modules. This hub focuses on actionable specs from A1 SolarStore's inventory for faster decisions.

How do solar panels cut home bills?

Panels use monocrystalline cells to generate DC power, inverted to AC for household use, with excess credited via net metering. For 1,500–3,000 sq ft homes, 6–10 kW systems (15–22 panels) offset most loads in sunny states.

Which panel types fit U.S. roofs best?

High-power 144-cell modules maximize output on large roofs; 108-cell options suit complex layouts; bifacial adds 5–20% yield on reflective surfaces.

Panel Type	Best For	Example Brands & Specs
High-Power Monofacial	Pitched roofs, max output	Regitec 550W (144 cells, 49.9V VOC); SolarSpace 580W (144 cells, 51.48V VOC)
Bifacial	Ground/flat roofs, albedo gain	Phono Solar 590W (144 cells, 52.68V VOC); JA Solar 535W (144 cells, 49.45V VOC); Axitec 550W US-made (144 cells, 50.2V VOC)
All-Black/Compact	Aesthetics, small roofs	Q CELLS 410W US-made (132 cells, 45.37V VOC); REC 420W (132 cells, 49.1V VOC)

Bifacial excels in snow-prone areas; monofacial prioritizes simplicity.
