在太陽能裝置中加入有機物動力源，可以在一年中最冷的幾個月為單層住宅提供100%的供暖，且有助于環保。在溫暖的月份，該系統可以產生盈余的電力，可以回售給電網。

在AIP出版社出版的《可再生和可持續能源雜志》上，中國和美國的研究人員概述了一個計算機模擬模型，通過增加生物質能作為另一種可再生能源來解決太陽能固有的間歇性的挑戰，以推進可靠的、可負擔的供熱解決方案，同時減少二氧化碳排放。

"我們展示了這種混合系統如何在單戶家庭中提供比化石燃料更清潔、更節能的加熱解決方案，"共同作者Gaoyang Hou說。"該系統在農村社區會很方便，那里的農場有大量的農業廢棄物形式的生物質，可以與太陽能發電相結合，以縮小城鄉電力差距，并在這個過程中幫助環境。"

擬議的太陽能-生物質能混合系統是基于分布式多發電技術，整合了光伏-熱能(PV/T)和生物質能源。

生物質是由可再生的有機物產生的，如玉米皮、堅果殼、木漿以及食物和動物的廢棄物。由光伏板和熱能收集器組成的光伏/熱能系統是一種新興的技術，可以將太陽能轉化為熱能和電能，具有較高的能源轉換效率。

對新興的分散式混合系統的研究主要集中在社區和商業溫室農場。研究人員根據中國西北地區一棟單層平房從11月到3月的供暖需求對他們的系統進行了評估，該地冬天的溫度可能會降到零下20攝氏度(零下4華氏度)以下。

在總的能量輸入中，光伏/T集熱器產生了52%的電能，并獲得了8%的可用熱能。生物量產生了房屋供暖所需的其余40%的電力。

"共同作者Lei Xu說："在整個采暖季，太陽能在能源供應方面占主導地位，而生物質能源在需要時啟動，以彌補能源的不足。

他們在TRNSYS(瞬態系統仿真工具的簡稱)中創建了仿真模型，這是一個模塊化的熱系統軟件，用于評估熱能和電能可再生能源系統的性能。

他們的混合系統模擬包括光伏/T集熱器、熱泵、帶有浸入式盤管換熱器的儲罐、分流器和備用電鍋爐等部件。

研究人員正在開發一個太陽能-生物質能系統模型，以滿足一個小型商業建筑的供暖和制冷需求，如果成功的話，計劃開發一個原型進行實驗測試。

Solar-Biomass Hybrid System Satisfies Home Heating Requirements in Winter

Adding an organic matter power source to a solar energy unit could provide 100% heating for a single-story home during the coldest months of the year and help the environment. In the warmer months, the system could generate electricity surpluses that can be sold back to the grid.

In Journal of Renewable and Sustainable Energy, published by AIP Publishing, researchers in China and the United States outline a computer simulation model addressing the challenge of solar power’s inherent intermittency by adding biomass as another renewable energy source to advance a reliable, affordable heating solution while reducing carbon dioxide emissions.

“We demonstrate how this hybrid system provides a cleaner, more energy-efficient heating solution than fossil fuel in single-family homes,” co-author Gaoyang Hou said. “The system would be convenient in rural communities, where farms have large amounts of biomass in the form of agricultural waste that can be combined with solar power to close the urban-rural electricity gap and help the environment in the process.”

The proposed solar-biomass hybrid system is based on distributed multi-generation technology that integrates photovoltaic-thermal (PV/T) and biomass power sources.

Biomass is produced from renewable organic matter, like corn husks, nut shells, wood pulp, and food and animal waste. A PV/T system, composed of PV panels and thermal collectors, is an emerging technology that converts solar energy into both heat and electricity with higher energy conversion efficiency.

Studies on emerging decentralized hybrid systems have focused on neighborhoods and commercial greenhouse farms. The researchers evaluated their system based on the heating needs of a single-story cottage from November to March in northwest China, where temperatures in winter can dip below minus 20 degrees Celsius (minus 4 degrees Fahrenheit).

Of the total energy input, the PV/T collector generated 52% of the electrical energy and captured 8% of the available thermal energy. The biomass generated the remaining 40% of the electricity needed to heat the house.

“For the entire heating season, solar power predominates the energy supply side, with the biomass energy generation kicking in when needed to make up the energy deficit,” co-author Lei Xu said.

They created their simulation model in TRNSYS (short for transient system simulation tool), a modular thermal system software used to assess the performance of thermal and electrical renewable energy systems.

Their hybrid system simulation consisted of a PV/T collector, heat pump, storage tank with an immersed coiled-tube heat exchanger, flow diverters, and backup electric boiler, among other components.

The researchers are developing a solar-biomass system model to meet heating and cooling demands of a small commercial building and, if successful, plan to develop a prototype for experimental testing.
