According to our database: **Horay Solar HS470TC-MHB-D** has higher module efficiency (**23.00%** vs **22.30%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Horay Solar HS470TC-MHB-D and Horay Solar HS475TC-MHB-D? **Horay Solar HS470TC-MHB-D** has a module efficiency of **23.00%**, while **Horay Solar HS475TC-MHB-D** is **22.30%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Horay Solar HS470TC-MHB-D use vs Horay Solar HS475TC-MHB-D? **Horay Solar HS470TC-MHB-D** uses **N-type** cells; **Horay Solar HS475TC-MHB-D** uses **N-type**. 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 Horay Solar HS470TC-MHB-D and Horay Solar HS475TC-MHB-D? **Horay Solar HS470TC-MHB-D** has a **30 years** power warranty; **Horay Solar HS475TC-MHB-D** 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 Horay Solar HS470TC-MHB-D and Horay Solar HS475TC-MHB-D bifacial panels? Both **Horay Solar HS470TC-MHB-D** and **Horay Solar HS475TC-MHB-D** 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 - [Horay Solar HS470TC-MHB-D vs Horay Solar HS465TC-MHB-D](https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs465tc-mhb-d) - One difference: module efficiency - [Horay Solar HS470TC-MHB-D vs Horay Solar HS460TC-MHB-D](https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs460tc-mhb-d) - 3 differences, the largest is module efficiency - [Horay Solar HS470TC-MHB-D vs Horay Solar HS455TC-MHB-D](https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs455tc-mhb-d) - 3 differences, the largest is module efficiency - [Horay Solar HS470TC-MHB-D vs Horay Solar HS720TC-MHG-D](https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs720tc-mhg-d) - 11 differences, the largest is rated power - [Horay Solar HS470TC-MHB-D vs Horay Solar HS710TC-MHG-D](https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs710tc-mhg-d) - 10 differences, the largest is rated power - [Horay Solar HS470TC-MHB-D vs Horay Solar HS700TC-MHG-D](https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs700tc-mhg-d) - 12 differences, the largest is rated power --- Source: https://comparepv.com/compare/horay-solar-hs470tc-mhb-d/horay-solar-hs475tc-mhb-d 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.
