Batteries
side by side.
| Battery | Usable Capacity | Chemistry | Cycle Life | Warranty | Scalable | Best For |
|---|---|---|---|---|---|---|
| Tesla Powerwall 3 | 13.5–54 kWh | LFP | Unlimited* | 10 yr | Stackable | Whole-home |
| BYD Battery-Box | 5.1–22.1 kWh | LFP | 6,000+ | 10 yr | Stackable | Modular scaling |
| Sungrow SBR / SBH | 9.6–40 kWh | LFP | 6,000+ | 10 yr | Stackable | Inverter-matched |
| GoodWe Lynx / ESA | 5.4–48 kWh | LFP | 6,000+ | 10 yr | Stackable | All-in-one backup |
| Sigenergy SigenStor | 5–48 kWh | LFP | 10,000 | 10 yr | Modular 5-in-1 | AI + EV |
| AlphaESS SMILE | 9.3–37.2 kWh | LFP | 6,000+ | 10 yr | Stackable | Budget pick |
| FoxESS EQ4800 / CQ6 / CQ7 | 9.3–97 kWh | LFP | 6,000+ | 10–12 yr | Stackable | Long warranty |
| Enphase IQ Battery 5P | 5–80 kWh | LFP | 6,000 | 15 yr | Modular | Reliability |
| Pylontech Force H3 / H3X | 9.7–34 kWh | LFP | 8,000+ | 10 yr | Stackable | Value scaling |
Figures are for current flagship residential models (Jun 2026) and vary by variant; usable capacity spans a single unit to a typical max residential stack. LFP = lithium iron phosphate; all listed batteries are VPP-ready. Cycle Life shows each maker's stated rating — most brands now warrant by time and/or energy throughput rather than a fixed cycle count, and Tesla's warranty is time-based (10 yr, unlimited cycles). Pylontech is 10 yr on registration. Exact capacity, cycle and warranty terms confirmed per model at quote.
Solar panels
compared.
| Brand | Cell Technology | Module Efficiency | Product Warranty | Performance Warranty | Best For |
|---|---|---|---|---|---|
| Trina Solar | N-type TOPCon | 23.8% | 25 yr | 30 yr | Most shipped |
| LONGi Solar | Back-contact (HPBC) | up to 24.8% | 15–25 yr* | 30 yr | Efficiency leader |
| JA Solar | N-type TOPCon | 22.5% | 25 yr | 30 yr | Value + bankability |
| Canadian Solar | N-type TOPCon | 23.2% | 25 yr | 30 yr | Bankability |
| Jinko Solar | N-type TOPCon | 23.8% | 25 yr | 30 yr | Best value |
| REC Group | HJT | 22.6% | 20–25 yr* | 25 yr | Hail-resilient |
| SunPower / Maxeon | IBC Maxeon | 24.1% | 40 yr | 40 yr | Maximum output |
| Q CELLS | N-type TOPCon | 22.5% | 25 yr | 25 yr | Shade tolerance |
Module efficiency is each brand's current flagship residential variant (Jun 2026) and varies by model. Product = panel build warranty; Performance = guaranteed output. * LONGi's Hi-MO X10 datasheet lists 15 yr product (often 25 yr via AU retail / dual-glass variants); REC is 20 yr, extending to 25 yr under a ProTrust certified install. We confirm the exact model, efficiency and warranty in your written quote.
