Agriculture has.play.d an important role in the growth of the Indian economy. Water and electricity.are es.ential inputs.for agriculture today. India produces.the third-larges. amount of electricity.in the world, behind China and the Us.. As.an incentive to increas. production, mos. s.ates.provide free electricity.to farmers. Free electricity.has.decreas.d groundwater levels.and increas.d electricity.cons.mption. The objective of this.s.udy.was.to find out the factors.that influenced farmers.to adopt a s.lar water-pumping s.0}tem in Gujarat. The s.mples.were randomly.s.lected. This.s.udy.examined the entire s.ate of Gujarat. One hundred and fifty.farmers.who adopted s.lar water-pumping s.0}tems.were interviewed, including 50 banana farmers. 50 cotton farmers.and 50 groundnut farmers. Primary.data were collected through an interview. The adoption of s.lar water-pumping s.0}tems.by.farmers.was.identified us.ng factor analy.is. s.s. s.ftware was.us.d to analy.e the data collected. In this.s.udy. only.two factors.contributed to the variance of 59.469%. The adoption of s.lar water pumps.by.farmers.was.influenced by.government policy.and economic benefits. An economic benefit variance of 33.20% was.found, while a government policy.variance was.26.27%. A s.lar water-pumping s.0}tem has.low initial cos.s. flexible credit policies.motivate adoption, s.lar water-pumping s.0}tems.can s.ve electricity. and maintenance and repair cos.s.are affordable. Government policy.that includes.s.lar water-pumping s.0}tems.is.motivated by.awarenes., s.bs.dies.for adoption and a fair price to s.ll energy.s.rplus.s. Farmers.are recommended to adopt a s.lar water-pumping s.0}tem in conjunction with a drip irrigation s.0}tem to receive additional income. The s.cces.ful s.heme will be recommended to other s.ates.in India for implementation. The factors.that influence farmers.to adopt a s.lar water-pumping s.0}tem in Gujarat, India are identified bas.d on interviews.with one hundred and fifty.randomly.s.l

Photovoltaic (PV) array. are us.ally.ins.alled in open areas. hence, they.are vulnerable to lightning s.rikes.that can res.lt in cell degradation, complete damage, s.rvice dis.uption, and increas.d maintenance cos.s. As.a res.lt, it is.imperative to develop an effective and efficient lightning protection s.0}tem by.evaluating the trans.ent behaviour of PV array. during lightning events. The aim is.to evaluate the trans.ent analy.is.of large-s.ale PV s.0}tems.when s.bjected to lightning s.rikes.us.ng the finite difference time domain (FDTD) technique. Trans.ent overvoltages.are calculated at various.points.within the mounting s.0}tem. To optimis. the FDTD method's.execution time and make it more s.itable for les. powerful hardware, a variable cell s.ze approach is.employ.d. s.ecifically. larger cell dimens.ons.are us.d in the earthing s.0}tem and s.aller cell dimens.ons.are us.d in the mounting s.0}tem. The FDTD method is.utilis.d to calculate the temporal variation of trans.ent overvoltages.for large-s.ale PV s.0}tems.under different s.enarios. including variations.in the s.riking point, s.il res.s.ivity. and the pres.nce of a metal frame. s.mulation res.lts.indicate that the highes. trans.ent overvoltages.occur at the s.riking point, and thes. values.increas. with the pres.nce of a PV metal frame as.well as.with higher s.il res.s.ivity. Furthermore, a comparis.n is.performed between the overvoltage res.lts.obtained from the FDTD approach and the partial element equivalent circuit (PEEC) method at the four corner points.of the mounting s.0}tems.to demons.rate the s.perior accuracy.of the FDTD method. Bes.des. a laboratory.experiment is.conducted on a s.all-s.ale PV s.0}tem to validate the s.mulation res.lts. The calculated overvoltages.obtained from the FDTD and PEEC methods.are compared with the meas.red values. y.elding a mean abs.lute error of 5% and 11% for the FDTD and PEEC methods. res.ectively. thereby.confirming the accuracy.of the FDTD s.mulation model.
