Rooftop Solar Installer & PM Surya Ghar Government-Registered Vendor, Samastipur, Bihar
Solar system choose karte time teen main options hote hain — on-grid, off-grid, aur hybrid. Yeh full guide Bihar ke context mein teeno ko detail mein compare karti hai, taaki aap subsidy, cost, backup aur long-term value — sab dekh kar sahi decision le sakein.
On-Grid Solar System
On-grid system seedha DISCOM ke grid se net-metering ke through connected hota hai. Battery nahi hoti — din mein jitni bijli banti hai use hoti hai, extra grid mein export hoti hai aur bill mein credit ban jaata hai.
| Aspect | Details |
|---|---|
| Subsidy Eligible | ✅ Haan — poori ₹98,000 tak |
| Battery | ❌ Nahi |
| Cost | Sabse kam (teeno mein se) |
| Grid Cut Mein Bijli | ❌ Nahi (safety shutdown) |
| Best For | Wo ghar jinke area mein grid reliable hai |
Off-Grid Solar System
Off-grid system battery storage ke saath completely independent chalta hai, grid se koi connection nahi hota.
| Aspect | Details |
|---|---|
| Subsidy Eligible | ❌ Nahi |
| Battery | ✅ Zaroori |
| Cost | Sabse zyada (battery ki wajah se) |
| Grid Cut Mein Bijli | ✅ Haan |
| Best For | Remote areas jahan grid connection hi nahi hai |

Bihar Ke Liye Hamari Overall Recommendation
Bihar ke zyadatar urban aur semi-urban areas mein grid connection reasonably reliable hai, isliye 90% households ke liye on-grid hi sabse practical choice hota hai — sabse kam cost, poori subsidy, aur fast payback. Hybrid tab consider karein jab aapko koi zaroori equipment chalana ho jo bijli cut se affect na ho — jaise medical devices ya home business. Pure off-grid sirf un rare cases ke liye recommend karte hain jahan grid connection bilkul available hi nahi hai, kyunki subsidy chhoot jaane se effective cost bahut zyada ho jaata hai.

Zyadatar hybrid-ready inverters ke saath yeh possible hota hai — battery baad mein add ki ja sakti hai. Lekin yeh specific inverter model par depend karta hai, isliye shuru mein hi discuss karna behtar hota hai.
PM Surya Ghar Yojana ka main goal grid-connected rooftop solar ko promote karna hai jisse DISCOM ka load kam ho aur net-metering ke through bijli grid mein wapas jaaye. Off-grid systems grid se connected hi nahi hote, isliye scheme ke scope se bahar aate hain.
Battery type par depend karta hai — typically 5-10 saal, uske baad replacement zaroori hoti hai. Yeh ek ongoing maintenance cost hai jo on-grid system mein nahi hoti.
Agar cuts rare hain aur koi critical equipment nahi hai jo bijli cut se affect ho, to on-grid hi sufficient hai aur zyada cost-effective bhi. Battery tabhi zaroori hai jab guaranteed uninterrupted power chahiye.
