According to our database: **Horay Solar HS630TC-MHC-D** has higher module efficiency (**23.30%** vs **23.10%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Horay Solar HS625TC-MHC-D and Horay Solar HS630TC-MHC-D? **Horay Solar HS625TC-MHC-D** has a module efficiency of **23.10%**, while **Horay Solar HS630TC-MHC-D** is **23.30%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Horay Solar HS625TC-MHC-D use vs Horay Solar HS630TC-MHC-D? **Horay Solar HS625TC-MHC-D** uses **TOPCon** cells; **Horay Solar HS630TC-MHC-D** 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 Horay Solar HS625TC-MHC-D and Horay Solar HS630TC-MHC-D? **Horay Solar HS625TC-MHC-D** has a **30 years** power warranty; **Horay Solar HS630TC-MHC-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 HS625TC-MHC-D and Horay Solar HS630TC-MHC-D bifacial panels? Both **Horay Solar HS625TC-MHC-D** and **Horay Solar HS630TC-MHC-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 HS625TC-MHC-D vs Horay Solar HS620TC-MHC-D](https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs620tc-mhc-d) - One difference: module efficiency - [Horay Solar HS625TC-MHC-D vs Horay Solar HS615TC-MHC-D](https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs615tc-mhc-d) - 3 differences, the largest is module efficiency - [Horay Solar HS625TC-MHC-D vs Horay Solar HS610TC-MHC-D](https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs610tc-mhc-d) - 3 differences, the largest is module efficiency - [Horay Solar HS625TC-MHC-D vs Horay Solar HS720TC-MHG-D](https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs720tc-mhg-d) - 6 differences, the largest is rated power - [Horay Solar HS625TC-MHC-D vs Horay Solar HS710TC-MHG-D](https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs710tc-mhg-d) - 7 differences, the largest is rated power - [Horay Solar HS625TC-MHC-D vs Horay Solar HS700TC-MHG-D](https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs700tc-mhg-d) - 9 differences, the largest is rated power --- Source: https://comparepv.com/compare/horay-solar-hs625tc-mhc-d/horay-solar-hs630tc-mhc-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.
