summary

Concrete numbers and hardware choices determine viability: a 52×52 mm 0.3 W panel into a linear regulator delivers ~0.15 Wh/day in winter after ~37% losses so about 63% system efficiency, a 250 F lithium‑ion capacitor provides roughly two weeks of no‑sun runtime and is rated for 50,000 cycles, PVGIS guides sizing by worst month, testing on rooftops and light boxes shows multi‑day dark stretches then quick recoveries, glass/ETFE laminates vs urethane decide durability.
