根據 Mordor Intelligence 預測,太陽能發電市場的裝置容量預計將在 2025 年達到 2.34兆瓦,2026 年達到 2.91兆瓦,到 2031 年達到 7.23兆瓦,2026 年至 2031 年的複合年成長率為 19.92%。

本報告按技術(單晶矽、多晶矽、薄膜、疊層/鈣鈦礦)、安裝類型(地面安裝、屋頂/建築整合太陽能、漂浮式)、最終用戶(住宅、商業/工業、公用事業規模獨立發電項目)和地區(北美、歐洲、亞太、南美、中東和非洲)進行細分。市場預測以總波數(GW)為單位。
2025年7月,中國離岸價(FOB China)下的太陽能現貨價格高峰跌至每瓦0.082美元,較2024年初下降32%。這項跌幅使得適用市電平價的國家數量增加至142個,在這些國家,公用事業規模的太陽能發電比煤炭或天然氣發電便宜15%至25%。 2025年,前五名供應商佔了68%的出貨量,加速了市場整合。公用事業規模專案21%、屋頂系統19%的監管能源效率標準確保了性能標準。為此,開發商已開始整合組件生產和EPC服務,以恢復利潤率。根據期貨價格曲線,預計到2027年,隨著N型TOPCon技術在製造成本方面與PERC技術相媲美,價格還將進一步下降10%至15%。
一項針對組件每瓦直流電0.07美元、電池每瓦直流電0.04美元的第45X條稅額扣抵,促成了一項到2025年投資100億美元的工廠建設計畫。 First Solar位於路易斯安那州的工廠計畫於2026年新增3.5吉瓦的薄膜太陽能電池產能。 2024年,美國國內組件產量達到12吉瓦(直流電),但僅滿足了國內需求的8%。財政部指南,到2027年,美國製造的成本佔比必須達到55%,才能獲得全額30%的投資稅額扣抵。垂直整合的供應鏈已將前置作業時間縮短至八週,並將東海岸專案的運輸成本降低了40%。
2023年,加州可再生能源發電減少了260萬兆瓦時,相當於38.5萬戶家庭的年用電量。夜間發電量波動導致燃氣調峰電廠的週期成本每兆瓦時增加15至20美元。德州電力可靠性委員會(ERCOT)預測,到2028年,德克薩斯的太陽能發電量將超過輸電能力,導致每年減少400萬兆瓦時的發電量。 2024年,德國向受限電影響的發電公司支付了12億歐元的補償金。南澳對住宅太陽能發電系統實施了動態輸電限制,導致居民用電收入減少了12%至18%。由於美國電網接入等待容量超過2000吉瓦,電網擴建計畫預計需要10年時間,這將迫使開發商在「表後」位置安裝太陽能發電系統,對太陽能市場構成重大挑戰。
2025年,單晶矽太陽能板在市場中維持了86.1%的佔有率,其電池效率達到27.81%,進一步鞏固了主導地位。預計到2031年,先進的疊層和鈣鈦礦組件的市場規模將以31.1%的複合年成長率成長。這得歸功於牛津光伏公司(Oxford PV)的商業產品實現了24.5%的效率和10,000小時的穩定性里程碑。多晶矽的市佔率下降至8.2%。這是由於製造商轉向N型TOPCon和異質接面生產線,這些技術在成本相近的情況下可帶來1.5-2個百分點的效能提升。
預計到2025年,主要公司將在研發方面投資超過12億美元,專注於研發雙面、半切和多匯流排佈局的太陽能板,以實現600瓦或以上的功率等級。薄膜碲化鎘(CdTe)太陽能板保持4.9%的市佔率。由於其溫度係數低,且能夠提高年發電量3%至5%,因此在炎熱氣候下的電力設施中備受青睞。資金籌措的確定性取決於是否符合IEC 61215和IEC 61730標準,這些標準構成了融資條款的基礎,並可將債務利差降低至多50個基點。
到2025年底,亞太地區將佔全球裝置容量的64.3%,主要得益於中國新計畫和印度累積新增的85吉瓦裝置容量。在日本,由於上網電價補貼(FIT)政策的逐步下調,住宅太陽能發電的成長速度有所放緩,但由於液化天然氣價格波動加劇了人們對價格穩定性的關注,企業購電協議(PPA)數量增加了62%。在東協市場,由於優惠融資政策將債務溢價降低了30-40個基點,新增裝置容量達到18吉瓦。在澳大利亞,居民太陽能發電普及率達38%,但由於可再生能源佔比高的州實施動態出口上限,資金轉向了公用事業規模的太陽能發電+儲能系統。
中東和非洲地區預計將以21.5%的複合年成長率成長,這主要得益於沙烏地阿拉伯的「2030願景」藍圖(58.7吉瓦)和阿拉伯聯合大公國的杜拜園區擴建計畫(5吉瓦)。沙烏地阿拉伯的蘇代爾電廠(裝置容量1.5吉瓦)創下了每度電0.0104美元的最低競標價格紀錄。阿拉伯聯合大公國的努爾阿布達比電廠目前滿足了當地10%的電力需求,並透過輸電網聯網線路向波斯灣地區出口電力。南非在第六輪競標中獲得了3.2吉瓦的訂單,但由於輸電網的限制,推遲了其中1.8吉瓦的部署。奈及利亞將於2025年部署一個450兆瓦的微電網,為280萬人供電。
到2025年,北美太陽能裝置容量佔全球的12.8%。美國新增裝置容量32吉瓦,其中德克薩斯州的年成長率超過加州。加拿大的清潔電力稅額扣抵(30%)促進了亞伯達和安大略省總計2.5吉瓦的裝機量成長。在墨西哥,淨計量系統的不確定性減緩了住宅太陽能裝置速度。歐洲佔了9.4%的市場。德國新增裝置容量8.5吉瓦,西班牙新增裝置容量6.2吉瓦,但由於二氧化碳價格約每噸90歐元,這兩個地區的裝置量都面臨碳定價的壓力。 2025年,巴西的分散式發電裝置容量將達到18吉瓦,並且剩餘電力零售補貼政策將全面維持。
According to Mordor Intelligence, the solar photovoltaic market size in terms of installed base is projected to be 2.34 Terawatt in 2025, 2.91 Terawatt in 2026, and reach 7.23 Terawatt by 2031, growing at a CAGR of 19.92% from 2026 to 2031.

This report is Segmented by Technology (Monocrystalline-Si, Multicrystalline-Si, Thin-Film, Tandem/Perovskite), Deployment Type (Ground-Mounted, Rooftop/BIPV, Floating PV), End-User (Residential, Commercial and Industrial, Utility-Scale IPPs), and Geography (North America, Europe, Asia-Pacific, South America, Middle East and Africa). The Market Forecasts are Provided in Terms of Volume (GW).
Spot prices in the Solar PV market dropped to USD 0.082 per watt-peak FOB China in July 2025, a 32% fall from early 2024. The decrease expanded grid-parity to 142 nations where utility-scale solar now undercuts coal and gas generation by 15-25%. Market consolidation accelerated as the five largest suppliers controlled 68% of 2025 shipments. Regulatory efficiency thresholds of 21% for utility projects and 19% for rooftop systems safeguard performance standards. Developers responded by integrating module production and EPC services to recapture margin. Forward price curves suggest another 10-15% decline by 2027 as N-type TOPCon technology achieves manufacturing parity with PERC.
Section 45X credits of USD 0.07 per watt-dc for modules and USD 0.04 per watt-dc for cells spurred USD 10 billion of factory announcements through 2025. First Solar's Louisiana plant adds 3.5 GW of thin-film output in 2026. Domestic module production reached 12 GW dc in 2024, yet satisfied only 8% of local demand. Treasury guidance now requires 55% U.S. cost content by 2027 to qualify for the full 30% investment tax credit. Vertically integrated supply chains cut lead times to eight weeks and slashed freight costs by 40% for East Coast projects.
California curtailed 2.6 million MWh of renewable electricity in 2023, equal to 385,000 homes' annual use. Evening ramps increase gas-peaker cycling costs by USD 15-20 per MWh. ERCOT foresees 4 million MWh of curtailment each year by 2028 as West-Texas solar surpasses transmission capacity. Germany paid EUR 1.2 billion to compensate curtailed generators in 2024. South Australia imposed dynamic export limits on rooftop systems, cutting household feed-in revenue 12-18%. U.S. interconnection queues above 2,000 GW stretch upgrade timelines to a decade, posing a key challenge for the Solar photovoltaic PV market by pushing developers toward behind-the-meter installations.

Monocrystalline silicon maintained 86.1% solar panels market share in 2025 as cell efficiencies reached 27.81%, reinforcing its leadership in the Solar PV industry. The solar panels market size for advanced tandem and perovskite modules is forecast to grow at 31.1% CAGR through 2031, reflecting Oxford PV's 24.5% commercial products and 10,000-hour stability milestones. Multicrystalline declined to 8.2% as producers migrated toward N-type TOPCon and heterojunction lines that lift performance by 1.5-2 percentage points at comparable costs.
Investment in R&D topped USD 1.2 billion among leading firms in 2025, focusing on bifacial, half-cut, and multi-bus-bar layouts that push 600 W-plus panel ratings. Thin-film cadmium-telluride retained a 4.9% share, favored for hot-climate utility sites where lower temperature coefficients elevate annual energy yield 3-5%. Bankability hinges on IEC 61215 and IEC 61730 compliance, which underpins financing terms and lowers debt margins by up to 50 basis points.
Asia-Pacific closed 2025 with 64.3% of global installed capacity, driven by China's 210 GW of new projects and India's 85 GW cumulative base. Japan's feed-in tariff step-down slowed rooftop growth, but corporate PPAs advanced 62% as LNG volatility spurred interest in price stability. ASEAN markets added 18 GW thanks to concessional finance that trimmed debt premiums 30-40 basis points. Australia's household penetration reached 38%, yet dynamic export caps in high-renewables states redirected capital toward utility-scale solar-plus-storage.
The Middle East and Africa are set for a 21.5% CAGR, supported by Saudi Arabia's 58.7 GW Vision 2030 roadmap and the UAE's 5 GW Dubai park expansion. Saudi Arabia's 1.5 GW Sudair plant achieved a record USD 0.0104 per kWh bid price. The UAE's Noor Abu Dhabi now covers 10% of local demand and exports into the Gulf interconnector. South Africa awarded 3.2 GW in Bid Window 6 but postponed 1.8 GW due to grid constraints. Nigeria deployed 450 MW of mini-grids in 2025, extending service to 2.8 million people.
North America accounted for 12.8% of the solar photovoltaic market capacity in 2025. The United States added 32 GW, with Texas surpassing California in annual additions. Canada's 30% clean-electricity tax credit stimulated 2.5 GW across Alberta and Ontario. Mexican rooftop deployment slowed amid net-metering uncertainty. Europe captured a 9.4% share; Germany installed 8.5 GW and Spain 6.2 GW under carbon-price pressures near EUR 90 per t CO2. Brazil's distributed-generation base hit 18 GW in 2025, retaining full retail credit for exports.
