英國太陽能發電：市場佔有率分析、行業趨勢和統計數據以及成長預測（2026-2031 年）

根據 Mordor Intelligence 預測，英國太陽能發電市場（以裝置容量計算）預計將從 2026 年的 20.85 吉瓦成長到 2031 年的 32.5 吉瓦，在預測期（2026-2031 年）內複合年成長率為 9.28%。

本報告按技術（光伏和聚光型太陽光電）、併網類型（併網和離網）以及最終用戶（大型發電、工商業和住宅）進行細分。市場規模和預測以裝置容量（GW）表示。

英國太陽能市場趨勢與洞察

延長可再生能源強制令（ROE）證書將促進企業購電協議（PPA）的簽訂。

可再生能源授權證書 (ROC) 計畫有效期至 2027 年 3 月，支援 10 至 15 年的購電協議 (PPA)，使製造商和資料中心能夠在滿足資訊揭露要求的同時，對沖批發價格波動帶來的風險。集中在蘇格蘭和英格蘭的工業需求吸收了中午時段的發電量，從而降低了發電限制的風險。 ROC 較低的價格上限緩解了初期現金流風險，並促進了中型開發商獲得銀行融資，儘管預計在計劃結束前會出現專案運作高峰。如果 2027 年以後沒有大規模的差價合約 (CFD)競標，相關活動可能會放緩。

在公用事業規模的專案中實現市電平價將加速商業太陽能的發展。

到2024年，隨著平準化發電成本降至每千瓦時0.045英鎊以下，英格蘭南部地區的項目將能夠依靠批發電力收入、嵌入式效益和輔助服務收入。面式組件和單軸追蹤器正在提升發電效率，GRIDSERVE位於約克的電站已證明，整合27兆瓦的儲能系統可確保多種價值來源。商業太陽能專案的可行性研究正在將專案集中在陽光充足的地區，吸引機構投資者資金並降低政策風險。

土地利用規劃的限制正日益成為一個嚴峻的挑戰。

由於被劃為農業用地，在1-3a級土壤上進行太陽能發電受到阻礙，核准流程可能需要18-24個月。薩默塞特郡和北約克郡的項目可能會被拒絕，除非它們能夠證明其用途為雙重用途或棕地位置。垃圾掩埋場土壤修復成本的掩埋進一步擠壓了利潤空間，迫使開發商將目光轉向威爾斯和蘇格蘭。

細分市場分析

預計到2025年，光伏技術將佔據英國太陽能市場100%的佔有率，並在2031年之前以9.3%的複合年成長率成長，這表明英國太陽能市場將繼續主導。北約克郡的現場測試表明，雙面組件的基準值單面組件高出15-17%，這支持了雙面組件的快速普及。半電池和多匯流排設計進一步提高了在低光源條件下的發電量，非常適合英國的漫射太陽輻射特性。

組件創新與逆變器發展趨勢密切相關。串列型逆變器因其成本效益高，在公用事業規模的太陽能電站中佔據主導地位；而微型逆變器則因其能夠減輕煙囪和樹木遮擋的影響，在屋頂光伏電站中日益普及。追蹤系統目前仍屬於小眾市場，但南安普敦大學的測試預計在2026年至2028年間量化雙軸追蹤系統在高緯度地區的價值。這些技術的進步將進一步鞏固其在英國整體太陽能市場中的地位。

United Kingdom Solar Power Market Trends and Insights

Renewable Energy Obligation Certificates Extension Spurs Corporate PPAs

The ROC window through March 2027 underpins 10-15-year corporate PPAs, letting manufacturers and data centers hedge volatile wholesale prices while meeting disclosure mandates. Industrial demand clusters in Scotland and England absorb midday generation, lowering curtailment risks. The ROC floor de-risks early cash flows, unlocking bank finance for mid-scale developers, yet a commissioning rush is expected before the mechanism sunsets. Without larger CFD rounds, post-2027 activity could soften.

Grid-Parity Achievement in Utility-Scale Projects Accelerates Merchant Solar

Levelized costs below GBP 0.045 per kWh in 2024 let southern English projects rely on wholesale, embedded-benefit, and ancillary-service revenues. Bifacial modules and single-axis trackers enhance yields, demonstrated by GRIDSERVE's York site, which integrates 27 MW storage to capture multiple value streams. Merchant viability concentrates pipelines in high-irradiance counties, attracting institutional capital and reducing policy risk.

Land-Use Planning Constraints Challenge Expansion

Agricultural land classifications hinder solar on Grade 1-3a soils, extending approvals to 18-24 months. Projects in Somerset and North Yorkshire face rejection unless dual-use or brownfield siting is proven. Elevated remediation costs on landfills further squeeze margins, shifting developers toward Wales and Scotland.

Other drivers and restraints analyzed in the detailed report include:

1. National Grid ESO Reform Favors Distributed Participation
2. Battery-Coupled Solar Economics Enhanced by Flexible Connection Code
3. Import Dependency Risk from Xinjiang Silicon

Segment Analysis

Solar photovoltaic technology captured 100% of the UK solar power market share in 2025 and is set to grow at a 9.3% CAGR through 2031, keeping the UK solar power market entirely PV-driven. Field tests in North Yorkshire show bifacial modules generating 15-17% more energy than monofacial references, validating rapid bifacial uptake. Half-cell and multi-busbar designs further boost low-light yields, aligning with the nation's diffuse-irradiance profile.

Module innovations dovetail with inverter trends: string inverters dominate utility arrays for cost efficiency, whereas microinverters prosper on rooftops by mitigating chimney and tree shading. Tracking remains niche, yet University of Southampton trials could quantify dual-axis value at high latitudes over 2026-2028. Collectively, these advancements reinforce the technology's lock-in across the UK solar power market.
