Solar Quotation ke Red Flags — Kya Dekhein
Local solar quotation mein hidden charges aur low-quality components kaise pehchanein. Structure gauge, AC wire shortcut, DISCOM fees aur subsidy guarantee ke red flags.
Seedha jawab
Solar quotation compare karte waqt sirf total price mat dekhiye. Market mein saste quotes aksar 4 jagah se cut lagakar bante hain: (1) Non-DCR panels dekar subsidy fasana, (2) Patle 1.2mm structure par 80-micron hot-dip galvanization skip karna, (3) Solar DC cable ki jagah normal domestic wire use karna jisse fire hazard hota hai, aur (4) CSPDCL net meter processing aur testing charges quote se gayab rakh kar baad mein extra maangna. Quotation sign karne se pehle hamesha component-wise Bill of Materials (BOM) demand karein.
Durg aur Bhilai mein aajkal bohot se naye contractors solar business mein aaye hain. Customer ko attract karne ke liye wo ₹20,000–₹30,000 sasta quote de dete hain. Lekin solar installation 25 saal ka asset hai — agar structure 3 saal mein zang lag kar jhuk gaya ya inverter har doosre din trip hota raha, to shuruat ki bachat bhaari nuksan mein badal jaati hai.
Quotation Check Karne Ka Red Flag Matrix
| Pehlu (Component) | Red Flag (Saste Contractor Ka Trick) | Professional Standard (Safe & Verified) |
|---|---|---|
| Panel Compliance | Sirf 'Tier-1 550W' likha hota hai, DCR certificate aur RFID mention nahi hota | MNRE ALMM listed, verified DCR Indian wafer certificate specified for subsidy |
| Mounting Structure | Pre-galvanized (thin zinc) ya normal paint wala loha jo 2 saal mein rust hota hai | Hot-Dip Galvanized (HDG) minimum 80-micron coating with 150 km/h wind certification |
| Electrical Cabling | Standard AC domestic wire DC side mein daal dete hain (fire risk) | Dedicated TUV-certified 4/6 sq.mm cross-linked solar DC copper cable with UV sheath |
| Earthing & Safety | Sirf 1 earthing rod ya normal namak-koyle wala pit | 3 separate chemical earthing pits (DC, AC, Lightning) with copper bonded electrodes |
| DISCOM Liaisoning | 'Meter charges separate' chote aksharon mein likha hota hai | Turnkey delivery — CSPDCL portal application, inspection & net meter fees fully covered |
Top 3 Hidden Costs Jo Quote Mein Chhupaye Jaate Hain
- CSPDCL Net Meter Testing & Connection Fee: Kuch contractors quote mein sirf panels aur inverter ka rate jodte hain. Baad mein jab net meter lagne ka time aata hai to kehte hain ki '₹8,000–₹12,000 CSPDCL meter charge alag se dena hoga'. Hamesha confirm karein ki quote all-inclusive turnkey hai.
- Civil Foundation Material: Rooftop structure ko anchor karne ke liye concrete blocks (grouting) zaroori hoti hain. Kaafi vendors cement, sand aur gitti customer se mangwate hain.
- Inverter Wi-Fi Stick & Monitoring Setup: Wi-Fi data-logger stick ke extra ₹2,500 maangna ek common trick hai. Professional quotes mein remote app monitoring standard bundled hoti hai.
Contract Sign Karne Se Pehle Vendor Se Poochhein Ye 4 Sawaal
- 1Sawaal 1: Kya panels par manufacturer ka original RFID tag glass ke andar hai aur unka serial number MNRE portal par check ho sakta hai?
- 2Sawaal 2: Structure par zinc coating kitne micron ki hai aur kya aap iska test certificate denge?
- 3Sawaal 3: Agar inverter mein fault aaya to local Durg/Bhilai mein replacement ya service support kitne ghante mein milega?
- 4Sawaal 4: Kya payment terms milestone-based hain (jaise advance, material delivery, installation, aur net meter testing ke baad)?
Frequently Asked Questions (FAQs)
Aksar poochhe jaane waale sawaal
- Kya quotation mein GST alag se lagta hai?
- Solar systems par 12% concessional GST structure apply hota hai (jisme 70% material par 12% aur 30% service par 18% ka composite formula lagta hai). Ensure karein ki quote GST-inclusive ho taaki aage chal kar bill mein achanak tax na jud jaaye.
- Non-DCR panel lagane se kya nuksan hai?
- Non-DCR panels lagane par aapko PM Surya Ghar ki ₹78,000 central subsidy nahi milegi. Agar aap subsidy chahte hain to panels mandatory DCR certified hone chahiye.
- Milestone payment schedule kaisa hona chahiye?
- Standard safe practice: 10%–20% booking advance, 60% material rooftop deliver hone par, 15% physical installation complete hone par, aur remaining 5% net meter lagne ke baad.
