According to our database: **KIOTO Solar KPV **445 Wp** HC NE (G/G-TC)** has higher module efficiency (**22.79%** vs **22.53%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of KIOTO Solar KPV 440Wp HC NE (G/G-TC) and KIOTO Solar KPV 445Wp HC NE (G/G-TC)? **KIOTO Solar KPV **440 Wp** HC NE (G/G-TC)** has a module efficiency of **22.53%**, while **KIOTO Solar KPV **445 Wp** HC NE (G/G-TC)** is **22.79%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does KIOTO Solar KPV 440Wp HC NE (G/G-TC) use vs KIOTO Solar KPV 445Wp HC NE (G/G-TC)? **KIOTO Solar KPV **440 Wp** HC NE (G/G-TC)** uses **TOPCon** cells; **KIOTO Solar KPV **445 Wp** HC NE (G/G-TC)** 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 KIOTO Solar KPV 440Wp HC NE (G/G-TC) and KIOTO Solar KPV 445Wp HC NE (G/G-TC)? **KIOTO Solar KPV **440 Wp** HC NE (G/G-TC)** has a **25 years** power warranty; **KIOTO Solar KPV **445 Wp** HC NE (G/G-TC)** has a **25 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 KIOTO Solar KPV 440Wp HC NE (G/G-TC) and KIOTO Solar KPV 445Wp HC NE (G/G-TC) bifacial panels? Both **KIOTO Solar KPV **440 Wp** HC NE (G/G-TC)** and **KIOTO Solar KPV **445 Wp** HC NE (G/G-TC)** 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 - [KIOTO Solar KPV 440Wp HC NE (G/G-TC) vs KIOTO Solar KPV 450Wp HC NE (G/G-TC)](https://comparepv.com/compare/kioto-solar-kpv-440wp-hc-ne-g-g-tc/kioto-solar-kpv-450wp-hc-ne-g-g-tc) - 6 differences, the largest is open-circuit voltage - [KIOTO Solar KPV 440Wp HC NE (G/G-TC) vs KIOTO Solar KPV 450 Wp HC NE](https://comparepv.com/compare/kioto-solar-kpv-440wp-hc-ne-g-g-tc/kioto-solar-kpv-450-wp-hc-ne) - 9 differences, the largest is product warranty - [KIOTO Solar KPV 440Wp HC NE (G/G-TC) vs KIOTO Solar KPV 450Wp HC](https://comparepv.com/compare/kioto-solar-kpv-440wp-hc-ne-g-g-tc/kioto-solar-kpv-450wp-hc) - 11 differences, the largest is performance warranty - [KIOTO Solar KPV 440Wp HC NE (G/G-TC) vs KIOTO Solar KPV 445Wp HC](https://comparepv.com/compare/kioto-solar-kpv-440wp-hc-ne-g-g-tc/kioto-solar-kpv-445wp-hc) - 11 differences, the largest is performance warranty - [KIOTO Solar KPV 440Wp HC NE (G/G-TC) vs KIOTO Solar KPV 440 Wp HCB](https://comparepv.com/compare/kioto-solar-kpv-440wp-hc-ne-g-g-tc/kioto-solar-kpv-440-wp-hcb) - 11 differences, the largest is performance warranty --- Source: https://comparepv.com/compare/kioto-solar-kpv-440wp-hc-ne-g-g-tc/kioto-solar-kpv-445wp-hc-ne-g-g-tc 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.
