在低收入和中等收入经济体中，太阳能家庭系统的部署-包括光伏板、电池和一些电器-正在迅速增加。这些系统的简单性使其易于部署，适用于远离集中式电网而无法获得电力的客户。然而，太阳能光伏和存储容量的大小是具有挑战性的，并且容易出错，实际上表现为中午充满电的电池-导致超过30%的潜在电力减少。这意味着失去了宝贵的能源，而这些能源本可以在没有太阳能家庭系统的情况下供应给附近的家庭。之前的工作提出了将现有的太阳能家庭系统互连以增加电力供应。在这项工作中，我们分析了太阳能家庭系统与其他无源节点连接的问题，考虑多余的能量，连接的成本和投资回收期。使用来自肯尼亚西部的实际消费，发电和结构位置的数据集，我们表明，一些社区的电力供应可以增加3倍以上。
The deployment of solar home systems -- consisting of a photovoltaic panel, battery, and a few appliances -- is increasing rapidly in low- and middle-income economies. The simplicity of these systems has made them easy to deploy for customers without access to electricity who are far from centralized grids. However, sizing of solar PVs and storage capacity is challenging and error-prone, which in practical terms manifests as a fully-charged battery by midday - resulting in a curtailment of more than 30% of potential electricity. This represents a loss of valuable energy that could have been supplied to nearby homes without solar home systems. Prior work has proposed interconnecting existing solar home systems to increase electricity access. In this work, we analyze the problem of connecting a solar home system with other passive nodes, considering excess energy, the cost of connection, and the payback period. Using datasets of actual consumption, generation, and structure locations from Western Kenya, we show that electricity access in some communities can be increased by more than 3x.
