So.ar ho.e systems fo. rural electrificatio. are o.ten designed with a limited energy supply, which presents a drawback fo. the techno.o.y. Furthermo.e, unco.tro.led livesto.k faeces in rural co.munities co.stitute enviro.mental sanitatio. and health risks. Livesto.k excrement can be used thro.gh a bio.as digester to.supplement so.ar energy to.pro.ide adequate and sustainable electricity access to.underserved rural co.munities while achieving waste management. Therefo.e, this study presents a hybrid so.ar-bio.as system fo. a mo.e dynamic energy supply and waste management fo. po.t-Co.id reco.ery plans in rural co.munities. A parametric research appro.ch that invo.ves the use o. the Integrated Enviro.ment So.utio. Virtual Enviro.ment so.tware applicatio. and mathematical mo.els to.design the desired ho.seho.d lo.d and the hybrid system sizing is used in the study. The findings sho. that the daily ho.seho.d energy co.sumptio. was 6.6 kWh, equivalent to.206.40 kWh/mo.th. A 1.2-kWp and 1.2-m3 hybrid so.ar-bio.as system was fo.nd to.adequately po.er the ho.se. Financially, the to.al initial investment co.t o. the system was $5777.20 with a net present value o. $6566.78, net pro.it o. $4443.6, a payback perio. o. 14 years and 8 mo.ths, and a levelized co.t o. energy o. $0.21/kWh; these include a 60% initial investment and maintenance co.ts subsidy. Energy perfo.mance co.tracting and energy-as-a-service were reco.mended to.effectively run and o.erate the system. The study successfully revealed the design, specificatio.s and upscaling mechanism o. the pro.o.ed hybrid so.ar-bio.as system. Mo.e research is required to.unveil the efficacy o. the system, the perfo.mance gap and the perceptio. o. the techno.o.y by the beneficiaries.
