How to Use This Calculator

Select your Aiko ABC panel model

Aiko Solar produces three residential/commercial ABC (All-Back-Contact) panel models. The Neostar 2P (460W, 24.0%) is the entry ABC — exceptional efficiency in a beautiful all-black design. The Neostar 3P (470W, 24.5%) is the flagship with the highest efficiency of any mass-produced panel. The Comet 590W is a large-format bifacial ABC for ground mounts and commercial rooftops.

Enter roof area, target size, PSH, and electricity rate

The calculator checks whether your target system size fits in your available roof area — Aiko's high efficiency means fewer panels for the same output. Enter your usable south-facing roof area, target kW, local peak sun hours, and electricity rate. The calculator shows panel count, whether they fit the roof, 25-year production, and payback period.

Understand the ABC technology advantage

All-Back-Contact technology moves all electrical contacts to the rear of the panel, eliminating front-side busbars entirely. This increases active cell area, improves aesthetics (uniform black appearance), and reduces shading losses from the contacts themselves. Aiko's ABC panels also have a -0.24%/°C temperature coefficient — the best in any mainstream panel — and 0.35%/yr degradation, lower than most TOPCon panels.

The Formula

Panel Area (sqft) = Panel Watts ÷ (Efficiency ÷ 100) ÷ 1000 × 10.764 Max Panels by Roof = ⌊Roof sqft ÷ Panel Area⌋ Panels Needed = ⌈Target kW × 1000 ÷ Panel Watts⌉ Year 1 Production = System kW × PSH × 365 × 0.80 × Bifacial Bonus Year N Production = Year 1 × (1 − 0.35%/yr)^N × (1 − 1.5% first-year) ABC Advantage vs PERC = 25yr ABC Total − 25yr PERC Total (0.35% vs 0.55%/yr) Cost = Panel Count × Panel Watts × $/W (model range ± $0.15)

Aiko's 1.5% first-year degradation (LID) is lower than conventional PERC (2–3%) because ABC panels have no Light-Induced Degradation mechanism — there is no p-type silicon exposed to light. The annual 0.35%/yr degradation is Aiko's warranted rate — matched only by a few premium TOPCon products and better than any PERC panel. Over 25 years, this compounds to a meaningful kWh advantage.

Example

Sophie — 8 kW target, 400 sqft roof, premium aesthetic, California

Sophie has a small 400 sqft south-facing roof section and wants the highest possible output with a beautiful aesthetic. She is in Southern California with 5.5 PSH and pays $0.27/kWh.

Sophie's small 400 sqft roof fits 17 Neostar 3P panels producing 8 kW — where standard 400W PERC panels would need 20 panels. The ABC technology's 24.5% efficiency means 17.6% fewer panels for the same output. The all-black aesthetic with no visible front busbars gives her roof a premium uniform look that standard panels cannot match.

FAQ

All-Back-Contact (ABC) technology moves all electrical contacts — both positive and negative — to the rear side of the solar cell. Standard panels have metal busbars running across the front face, which shade a small percentage of the active cell area. ABC eliminates front-side shading entirely, allowing more sunlight to reach the cells. This, combined with high-quality N-type silicon, enables Aiko to achieve 24.0–24.5% efficiency — among the highest of any commercially produced residential panel. The aesthetic result is a panel with a completely uniform black front face, no visible metal lines, which many homeowners and architects prefer for premium builds.
Aiko Solar was founded in 2009 and is based in Changzhou, China. They are a specialist ABC panel manufacturer — unlike Jinko or LONGi who produce multiple cell technologies, Aiko focuses exclusively on ABC. They have shipped GW-scale volumes to European, Australian, and North American markets. Aiko's Neostar series received top-performer status in PVEL's 2024 Solar Module PV Evolution Labs scorecard. As a smaller company than JinkoSolar or LONGi, Aiko carries slightly more counterparty risk, but their technical execution and warranty terms (30yr performance) are industry-leading. They are Bloomberg NEF Tier 1 listed.
Both are N-type technologies with excellent performance. Key differences: ABC (Aiko) has higher efficiency (24.0–24.5% vs 22.5–22.7%), better temperature coefficient (-0.24 vs -0.29%/°C), lower degradation (0.35 vs 0.40%/yr), and no front busbars for better aesthetics — at a 15–25% higher price per watt. TOPCon (Jinko) is a more established manufacturing process with a larger global supply chain, broader installer familiarity, and significantly lower cost per watt. For premium tight-roof or aesthetic-priority installs, Aiko ABC wins. For value-optimized installs with adequate roof space, Jinko Tiger Neo wins.
The temperature coefficient advantage of ABC technology comes from the cell architecture itself. In standard P-type PERC cells, the p-n junction's behavior under heat causes significant efficiency loss (-0.35%/°C). N-type TOPCon reduces this to -0.29%/°C. ABC goes further: because the contacts are on the rear, the cell can be thinner with less silicon to heat up, and the junction design is more thermally stable. At 60°C cell temperature (35°C above STC), Aiko panels lose only 8.4% power vs 10.2% for TOPCon and 12.25% for PERC. In hot climates like California, Arizona, Texas, or Queensland, this difference accumulates to hundreds of additional kWh per year.
