Compare Kingdom panels on ComparePV." source: "https://comparepv.com/reviews/kingdom-solar" --- # Kingdom panels, *read off the datasheets* Kingdom Solar (also known as KDM Kingdom Solar) is a Chinese solar module manufacturer based in Hefei, Anhui Province. The company produces monocrystalline solar panels for residential and commercial applications. Everything below is computed from those 3 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Kingdom does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2010 - **Headquarters:** Hefei, China - **Annual capacity:** 1 GW - **Employees:** 100 Company facts, not datasheet figures. Tier 1 is a financier's bankability list, and says nothing about how a panel performs. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 3 | models in the database | | Average efficiency | 22.5 % | across the catalogue | | Best efficiency | 22.8 % | their strongest module | | Power range | 440-590 Wp | smallest to largest | | Bifacial share | 0 % | 0 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Kingdom's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof. ### Most efficient module efficiency | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [KD-M590-144-N](https://comparepv.com/panel/kingdom-kd-m590-144-n) | 590 Wp | 22.8% (good) | | 2 | [KD-M440-108-N](https://comparepv.com/panel/kingdom-kd-m440-108-n-1) | 440 Wp | 22.5% (good) | | 3 | [KD-M570-144-N](https://comparepv.com/panel/kingdom-kd-m570-144-n) | 570 Wp | 22.1% (good) | - KD-M590-144-N - Monocrystalline - KD-M440-108-N - Monocrystalline - KD-M570-144-N - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/kingdom-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [KD-M590-144-N](https://comparepv.com/panel/kingdom-kd-m590-144-n) | 22.8% (good) | 590 Wp | | 2 | [KD-M570-144-N](https://comparepv.com/panel/kingdom-kd-m570-144-n) | 22.1% (good) | 570 Wp | | 3 | [KD-M440-108-N](https://comparepv.com/panel/kingdom-kd-m440-108-n-1) | 22.5% (good) | 440 Wp | - KD-M590-144-N - Monocrystalline - KD-M570-144-N - Monocrystalline - KD-M440-108-N - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/kingdom-solar?sort_by=power&sort_order=desc) ## 02. By what the array is for Three cuts of the same catalogue, each ordered by efficiency inside its band. An empty column means the brand does not build for that case. ### For a house roof 380-460 Wp | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [KD-M440-108-N](https://comparepv.com/panel/kingdom-kd-m440-108-n-1) | 440 Wp | 22.5% (good) | - KD-M440-108-N - Monocrystalline ### For a commercial array 500 Wp and up | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [KD-M590-144-N](https://comparepv.com/panel/kingdom-kd-m590-144-n) | 590 Wp | 22.8% (good) | | 2 | [KD-M570-144-N](https://comparepv.com/panel/kingdom-kd-m570-144-n) | 570 Wp | 22.1% (good) | - KD-M590-144-N - Monocrystalline - KD-M570-144-N - Monocrystalline ## 03. What the catalogue is made of Shares are of the 3 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one. [Cell technology across the market](https://comparepv.com/stats/cell-technology) ### Cell technology share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | N-type | 100.0% | 3 | N-type accounts for 100.0% of the catalogue - 3 of 3 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | 22-23% | 100.0% | 3 | ## 04. Strengths and gaps Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built. ### What this catalogue is good at - **Strength:** High-efficiency panels available (up to 22.8%) - **Strength:** Strong warranty coverage averaging 30 years - **Strength:** Large-scale production capacity of 1 GW ### Where it is thin - **Watch out:** Limited bifacial panel options - **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT) ## 05.
