即使在低日照地区，太阳能光伏发电（PV）也在上升。然而，在资本有限、土地稀缺或地理上孤立的农业社区的发展中国家，大型太阳能基础设施往往是不切实际的。在这些情况下，可能需要在现有作物上实施低密度光伏，以便将可再生能源服务纳入农村社区。在这里，我们以印度尼西亚为模型系统，研究了离网太阳能光伏与高价值作物种植相结合的土地利用、能源、温室气体排放、经济可行性和环境协同效益。生命周期分析表明，小规模双重土地利用系统在某些配置下在经济上是可行的，并有可能提供若干共同利益，包括农村电气化、改造柴油发电和为当地农产品加工提供电力。印度尼西亚一个示范村假设的全密度离网太阳能光伏发电显示，发电量（1907.5吉焦年- 1）远高于居民总消费量（678吉焦年- 1），这凸显了将光伏基础设施规模缩小一半以降低资本成本、同地种植和支持次级创收活动的机会。经济分析表明，半密度共址光伏系统的30年净当前电力成本（122.57亿印尼盾）明显低于产生同等电力所需的柴油固定成本（147.02亿印尼盾）。我们的分析通过优化土地利用效率和限制农业和森林地区转化为能源生产，为更智能的能源规划提供了见解。
Solar photovoltaics (PV) are on the rise even in areas of low solar insolation. However, in developing countries with limited capital, land scarcity, or with geographically isolated agrarian communities, large solar infrastructures are often impractical. In these cases, implementation of low-density PV over existing crops may be required to integrate renewable energy services into rural communities. Here, using Indonesia as a model system, we investigated the land use, energy, greenhouse gas emissions, economic feasibility, and the environmental co-benefits associated with off-grid solar PV when combined with high value crop cultivation. The life cycle analyses indicate that small-scale dual land-use systems are economically viable in certain configurations and have the potential to provide several co-benefits including rural electrification, retrofitting diesel electricity generation, and electricity for processing agricultural products locally. A hypothetical full-density off-grid solar PV for a model village in Indonesia shows that electricity output (1907.5 GJ yr−1) is much higher than the total residential consumption (678 GJ yr−1), highlighting the opportunity to downscale the PV infrastructure by half to lower capital cost, to co-locate crops, and to support secondary income generating activities. Economic analysis shows that the 30-year net present cost of electricity from the half-density co-located PV system (12,257 million IDR) is significantly lower than that of the flat cost of diesel required to generate equivalent electricity (14,702 million IDR). Our analysis provides insights for smarter energy planning by optimizing the efficiency of land use and limiting conversion of agricultural and forested areas for energy production.
