Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from. ## The two panels | Attribute | A | B | | --- | --- | --- | | Panel | [IBC Solar YH715W-33MHD/MH](https://comparepv.com/panel/ibc-solar-yh715w-33mhd-mh) | [IBC Solar YH720W-33MHD/MH](https://comparepv.com/panel/ibc-solar-yh720w-33mhd-mh) | | Manufacturer | IBC Solar | IBC Solar | | Power | 715 Wp | 720 Wp | | Efficiency | 23.02 % | 23.18 % | | Technology | TOPCon | TOPCon | ## Every compared parameter | Parameter | YH715W-33MHD/MH | YH720W-33MHD/MH | | --- | --- | --- | | Rated power | 715 Wp | 720 Wp | | Module efficiency | 23.02 % | 23.18 % | | Power density | 230.2 Wp/m² | 231.8 Wp/m² | | Open-circuit voltage | 49.58 V | 49.82 V | | Voltage at max power | 41.32 V | 41.52 V | | Short-circuit current | 18.09 A | 18.13 A | | Current at max power | 17.32 A | 17.34 A | | Temperature coefficient | -0.350 %/°C | -0.350 %/°C | | Dimensions | 2384x1303x33 mm | 2384x1303x33 mm | | Module area | 3.106 m² | 3.106 m² | | Weight | 38.0 kg | 38.0 kg | | Weight per kWp | 53.1 kg/kWp | 52.8 kg/kWp | | Product warranty | 30 yrs | 30 yrs | | Performance warranty | 30 yrs | 30 yrs | | Annual degradation | - | - | | Cell technology | TOPCon | TOPCon | | Cell type | Monocrystalline | Monocrystalline | | Cell count | 132 | 132 | | Bifacial | Yes | Yes | ## Thirty-year yield Declared first-year losses, with 0.40% a year afterwards assumed for both panels, at 1,200 kWh/kWp a year Same temp coeff. for both panels (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other. - **Cumulative output, YH715W-33MHD/MH:** 23,990 kWh - **Cumulative output, YH720W-33MHD/MH:** 24,157 kWh - **Gap:** 167 kWh ## Output when hot | Condition | Cell temperature | YH715W-33MHD/MH | YH720W-33MHD/MH | Retained | | --- | --- | --- | --- | --- | | Standard test conditions | 25 °C | 715 W | 720 W | 100.0% of rated power | | Cool, bright day | 40 °C | 677 W | 682 W | 94.8% of rated power | | Typical summer roof | 55 °C | 640 W | 644 W | 89.5% of rated power | | Hot roof | 70 °C | 602 W | 607 W | 84.2% of rated power | ## Against the whole database | Measure | YH715W-33MHD/MH | YH720W-33MHD/MH | Out of | Note | | --- | --- | --- | --- | --- | | Efficiency | #1,797 | #1,424 | 14,005 | YH720W-33MHD/MH leads by 373 places | | Power density | #2,018 | #1,347 | 14,005 | YH720W-33MHD/MH leads by 671 places | | Heat behaviour | #10,419 | #10,419 | 14,005 | Tied - the same position in the database | | Weight | #6,946 | #6,459 | 14,005 | YH720W-33MHD/MH leads by 487 places | | Warranty | #21 | #21 | 14,005 | Tied - the same position in the database | | Overall | #40 | #24 | 14,005 | YH720W-33MHD/MH leads by 16 places | ## Questions ### Which panel is better: IBC Solar YH715W-33MHD/MH or IBC Solar YH720W-33MHD/MH? According to our database: **IBC Solar YH**720 W**-33MHD/MH** has higher module efficiency (**23.18%** vs **23.02%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of IBC Solar YH715W-33MHD/MH and IBC Solar YH720W-33MHD/MH? **IBC Solar YH**715 W**-33MHD/MH** has a module efficiency of **23.02%**, while **IBC Solar YH**720 W**-33MHD/MH** is **23.18%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does IBC Solar YH715W-33MHD/MH use vs IBC Solar YH720W-33MHD/MH? **IBC Solar YH**715 W**-33MHD/MH** uses **TOPCon** cells; **IBC Solar YH**720 W**-33MHD/MH** uses **TOPCon**. Modern **n-type** technologies (**TOPCon**, **HJT**, BC) typically deliver higher efficiency and lower degradation compared to older **PERC** (p-type) cells. ### What is the warranty on IBC Solar YH715W-33MHD/MH and IBC Solar YH720W-33MHD/MH? **IBC Solar YH**715 W**-33MHD/MH** has a **30 years** power warranty; **IBC Solar YH**720 W**-33MHD/MH** has a **30 years** power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80**-87%**). Product (materials) warranties are usually shorter. ### Are IBC Solar YH715W-33MHD/MH and IBC Solar YH720W-33MHD/MH bifacial panels? Both **IBC Solar YH**715 W**-33MHD/MH** and **IBC Solar YH**720 W**-33MHD/MH** are bifacial - they capture reflected light from the ground, which can add 5**-15%** more annual energy on ground-mount or elevated rooftop installations with a light surface beneath. ## Related comparisons - [IBC Solar YH715W-33MHD/MH vs IBC Solar YH710W-33MHD/MH](https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-yh710w-33mhd-mh) - The same specification on paper - [IBC Solar YH715W-33MHD/MH vs IBC Solar YH550W-36MH](https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-yh550w-36mh) - 12 differences, the largest is module efficiency - [IBC Solar YH715W-33MHD/MH vs IBC Solar YH545W-36MH](https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-yh545w-36mh) - 12 differences, the largest is module efficiency - [IBC Solar YH715W-33MHD/MH vs IBC Solar YH540W-36MH](https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-yh540w-36mh) - 12 differences, the largest is module efficiency - [IBC Solar YH715W-33MHD/MH vs IBC Solar IBC Module White 455 MS-TA1](https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-ibc-module-white-455-ms-ta1) - 14 differences, the largest is temperature coefficient - [IBC Solar YH715W-33MHD/MH vs IBC Solar IBC Module Transparent 455 LS-TA2](https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-ibc-module-transparent-455-ls-ta2) - 12 differences, the largest is temperature coefficient --- Source: https://comparepv.com/compare/ibc-solar-yh715w-33mhd-mh/ibc-solar-yh720w-33mhd-mh Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
