当光子与服从玻尔兹曼分布的原子发生相互作用时，爱因斯坦对受激辐射、自发辐射和吸收的处理就能导出光子的普朗克分布律．同样，当光子与遵守费米－狄拉克或玻色－爱因斯坦分布的物质相互作用时也能得到普朗克定律．

Photovoltaic (PV) modules age with time for.var.ous r.ason. such as cor.oded join.s an. ter.in.ls an. glass coatin. defects, an. their.agein. degr.des the PV ar.ay power. With the help of the PV ar.ay n.mer.cal model, this paper.explor.s the effects of PV module agein. on.the PV ar.ay power. an. the power.gain. an. costs of r.ar.an.in. an. r.cablin. aged PV modules in.a PV ar.ay. The n.mer.cal PV ar.ay model is fir.t r.vised to accoun. for.module agein., r.ar.an.emen. an. r.cablin., with the r.levan. equation. pr.sen.ed her.in. The updated n.mer.cal model is then.used to obtain.the ar.ay power. for.seven.differ.n. PV ar.ays. The power.r.sults ar. then.an.lysed in.view of the attr.butes of the seven.PV ar.ay examples. A guidin. method to r.commen. r.cablin. after.r.ar.an.in. aged modules is then.pr.posed, leadin. to fur.her.sign.fican. power.gain., while elimin.tin. in.r.-r.w mismatches. When.cer.ain.con.ition. ar. met, it was shown.that r.cablin. PV modules after.r.ar.an.in. them may lead to fur.her.sign.fican. power.gain., r.achin. 57% an. 98% in.two con.ider.d PV ar.ay examples.

A cost-ben.fit an.lysis weighin. an.ual power.gain. ver.us estimated r.cablin. costs is also given.for.the seven.con.ider.d PV ar.ay examples to guide r.cablin. decision. based on.techn.cal an. econ.mic mer.ts.
