Teen Types Kyun Hote Hain?
Solar system choose karne se pehle ek fundamental sawaal — aapko battery chahiye ya nahi? Aur grid se connection chahiye ya nahi? Inhi do sawaalon ke basis pe teen systems bante hain.
1. On-Grid System (Grid-Tied)
On-grid system directly electricity grid se connected hota hai. Koi battery nahi hoti.
Kaise kaam karta hai:
- Din mein solar generate karta hai → ghar use karta hai
- Extra units net metering ke through grid mein jaate hain → credit milta hai
- Raat ko ya cloudy days mein grid se bijli aati hai
Pros:
- Sabse sasta (battery cost nahi)
- Net metering se maximum ROI
- Zero maintenance (battery nahi)
- PM Surya Ghar subsidy is par milti hai
Cons:
- Grid down hone par solar bhi band ho jaata hai (anti-islanding protection)
- Power cut mein kaam nahi karta
Kiske liye best:
- Jahan power cut kam ho (urban areas — Jaipur, Jodhpur, Ajmer)
- Maximum financial return chahiye ho
- Budget limited ho
Cost (3 kW): ₹1,50,000–₹2,00,000
2. Off-Grid System
Off-grid system bilkul independent hota hai — koi grid connection nahi, sirf battery.
Kaise kaam karta hai:
- Din mein solar generate karta hai → battery charge hoti hai
- Battery se raat ko aur cloudy days mein bijli milti hai
- No grid connection at all
Pros:
- Complete energy independence
- Remote locations mein useful jahan grid nahi
- Power cut se koi fark nahi
Cons:
- Bahut expensive (large battery bank chahiye)
- Battery 5–7 saal mein replace karni padti hai
- Oversized system design karna padta hai (cloudy days ke liye buffer)
- Net metering nahi, isliye ROI slow
Kiske liye best:
- Remote villages jahan grid nahi
- Agricultural pumping (seasonal)
- Telecom towers, remote cabins
Cost (3 kW equivalent): ₹3,00,000–₹4,50,000
3. Hybrid System
Hybrid best of both worlds hai — grid connection bhi, battery backup bhi.
Kaise kaam karta hai:
- Din mein solar → ghar use karta hai → extra battery charge hoti hai
- Battery full hone par extra units grid mein jaate hain
- Raat ko pehle battery use hoti hai, phir grid
- Power cut mein battery se backup milta hai
Pros:
- Power cut mein bhi kaam karta hai
- Net metering ka benefit bhi
- Flexible — battery size apni need ke hisaab se choose kar sakte hain
Cons:
- On-grid se mehnga (battery cost add hoti hai)
- Battery maintenance aur replacement
- PM Surya Ghar subsidy sirf solar component pe milti hai, battery pe nahi
Kiske liye best:
- Jahan power cut aate hain (semi-urban, small towns)
- Business jahan continuous power zaroori ho
- Ghar mein seniors ya patients ho
Cost (3 kW + 5 kWh battery): ₹2,80,000–₹3,50,000
Quick Decision Guide
| Situation | Recommended |
|---|---|
| City mein hain, power cut kam | On-Grid |
| Village mein, grid nahi | Off-Grid |
| City mein, power cut zyada | Hybrid |
| Business / shop | Hybrid |
| Maximum savings chahiye | On-Grid |
| Minimum maintenance | On-Grid |
Rajasthan Context
Rajasthan ke major cities (Jaipur, Jodhpur, Kota, Bikaner, Udaipur) mein DISCOM reliability improve hui hai. On-grid system 80% cases mein best choice hai. Rural Rajasthan ya semi-urban areas mein hybrid better kaam karta hai.
