solar panel lagvane se lambe samay mein bijli ka bill kam ho sakta hai, par shuruaati kharch bada hota hai. isliye soch-samjhakar aur kai jagah se jankari lekar faisla karen.
sabse pehle apni zaroorat samjhen:
1. pichhle 6 se 12 maheenon ke bijli bill dekhein aur ausat masik unit nikalen.
2. mota andaza: achhi dhoop vali jagah par 1 kilowatt ka sistam roz lagbhag 4 se 5 unit bana sakta hai. asli utpadan jagah, mausam aur chhaya par nirbhar karta hai.
3. chhat par saf aur chhaya-rahit jagah chahie. mote taur par 1 kilowatt ke liye lagbhag 10 varg meetar jagah lagti hai.
mukhy qismen:
1. on-grid: bijli vibhag ke meetar se juda hota hai. battery nahin lagti, isliye laagat kam rahti hai, par bijli jaane par yah chalna band ho sakta hai.
2. of-grid: battery ke sath aata hai. bijli jaane par bhi chalta hai, par battery ka kharch judta hai.
3. haibrid: donon ka mel, par keemat zyada.
kharidne se pehle ye janchen:
1. panel aur inverter ki warranty, aur kampani ka sarvis netvark.
2. panel ki gunvatta aur instolar ka anubhav. kam se kam 2 se 3 jagah se koteshan len.
3. sarkari subsidy yojnaon ki sharten aur rashi samay ke sath badlati rahti hain. apdet jankari ke liye sarkari portal ya apne bijli vibhag se pushti karen.
4. net metering ki prakriya aur shulk pehle poochh len.
5. bill mein sab kharch (panel, inverter, tar, instoleshan, GST) alag-alag likhvaen.
vapsi ka hisab lagaen: kul laagat ko salana bachat se bhag dekar dekhein ki kitne saal mein paisa vasool hoga.
