Solar lagwane se pehle 10 cheezein zaroor check kijiye
Quotation, warranty, structure, net metering aur subsidy — solar lagwane se pehle kaunse 10 sawaal poochhne chahiye taaki baad mein pachhtawa na ho.
Seedha jawab
Sabse zaroori 10 cheezein: panel aur inverter ka exact make/model, dono ki warranty alag-alag, mounting structure ka material aur height, cable aur protection ki quality, net metering kiske scope mein hai, subsidy process ka support, payment schedule, total timeline, after-sales service, aur sab kuch likhit quotation mein.
₹2–3 lakh ka faisla hai, aur system 20+ saal chalega. Thoda waqt lagakar ye sawaal poochh lena baad ki pareshani se bachata hai.
1. Panel ka exact make aur model
Sirf 'branded panel' kaafi nahi hai. Quotation mein brand, model number, wattage per panel aur kitne panels — sab likha hona chahiye. Agar subsidy chahiye to ye bhi confirm kijiye ki panels scheme ke applicable requirements (jaise DCR) pe khare utarte hain.
2. Inverter ka make, model aur capacity
Inverter system ka dimaag hai, aur aam taur par panels se pehle replace hota hai. Iska brand, capacity (kW), aur warranty period alag se poochhiye. Ye bhi poochhiye ki service support local hai ya nahi.
3. Warranty — teen alag cheezein hoti hain
| Kis cheez ki | Kya matlab |
|---|---|
| Panel product warranty | Panel ki physical build/manufacturing defect par |
| Panel performance warranty | Saalon baad bhi kitna output dega, uska assurance |
| Inverter warranty | Inverter ki apni alag warranty, aksar panels se kam |
4. Mounting structure
Structure ka material (GI, aluminium), height, aur wind load ke hisaab se design — ye long-term safety ka sawaal hai. Barsaat aur tez hawa yahan ki reality hai, isliye sasta structure mehanga pad sakta hai. Chhat mein waterproofing ka kya intezaam hai, ye bhi poochhiye.
5. Cable, protection aur earthing
DC/AC cable ki quality, surge protection, aur proper earthing — ye woh cheezein hain jo quotation mein aksar 'etc.' mein chhup jaati hain, aur wahi safety decide karti hain. Inhe line item ke roop mein likhwaiye.
6. Net metering kiske scope mein hai
Saaf poochhiye: net meter application, liaison aur charges — kya ye package mein hai ya extra? Kai baar customer ko baad mein pata chalta hai ki ye alag kharcha hai.
7. Subsidy process ka support
Vendor portal application, documentation aur inspection coordination mein madad karega ya nahi? Yaad rahe — koi bhi vendor subsidy approval ki guarantee nahi de sakta, sirf process mein madad kar sakta hai.
8. Payment schedule
- Advance kitna hai?
- Material delivery par kitna?
- Installation complete hone par kitna?
- Commissioning ke baad kuch balance rakha ja raha hai ya nahi?
9. Timeline — aur kis cheez ki guarantee nahi ho sakti
Installation ki timeline vendor de sakta hai. Lekin DISCOM approval, net meter aur subsidy disbursal ki exact date koi nahi de sakta. Jo vendor 'itne din mein subsidy aa jayegi' likh kar de, uspar bharosa mat kijiye.
10. After-sales — kaun, kaise, kitne din
Problem aane par kise call karna hai, response time kya hai, aur local team hai ya nahi. Ye sabse zyada tab important lagta hai jab 2 saal baad kuch issue aata hai.
Aksar poochhe jaane waale sawaal
- Sabse zaroori ek cheez kya hai?
- Likhit, itemised quotation — jisme panel/inverter ke make-model, warranty, structure, net metering aur payment schedule sab alag-alag likha ho.
- Site assessment ke bina quotation le sakta hoon?
- Ek indicative estimate to mil sakta hai, lekin final price chhat dekhe bina sahi nahi ho sakta. Assessment ke baad hi commit kijiye.
- Sasta vendor choose karna theek hai?
- Sirf price dekhna risky hai. Structure, cable aur inverter ki quality mein katauti baad mein mehangi padti hai. Same specification par prices compare kijiye, warna comparison bemani hai.
