Yeh sab se zyada poocha jane wala sawal hai jab koi pehli baar solar lagwane ka sochta hai, aur iska sab se sahi jawab kisi package mein nahi, balke aap ke pichle 12 mahine ke bijli bill mein hai.
Phir bhi, ek quick andaza ke liye: chota ghar (3 se 5 marla, 1 AC, bill Rs 15,000–25,000) ke liye 3kW se 5kW kaafi hai. Darmiyana ghar (10 marla, 2 AC) ke liye 5kW se 7.5kW chahiye. Bara ghar (1 kanal, 2 se 3 AC) ke liye 10kW ya usse zyada lagta hai.
Yeh sirf shuruati andaza hai. Neeche do sahi tareeqe diye gaye hain jin se aap apne ghar ka asal size nikal sakte hain, chahe aap ka purana bill ho ya aap naya ghar bana rahe hon jahan abhi bijli ka connection hi nahi laga.
Component rates dollar ke saath move karte hain, is liye aaj ka rate WhatsApp pe 03192070022 se confirm kar lein.
Tareeqa 1: apne bijli bill se size nikalein (sab se sahi tareeqa)
Agar aap ke ghar mein pehle se bijli ka meter laga hua hai, yeh sab se accurate tareeqa hai.
Pichle 12 mahine ke bills nikalein aur har mahine ke units note karein, rupee nahi, kyun ke tariff badalti rehti hai lekin units aap ki asal consumption batati hain. In sab ka average nikal lein.
Ek working rule ke tor par, 1kW solar system roughly 4 se 5 units per din deta hai Pakistan ke halaat mein.
| Aapka average monthly bill (units) | Suggested system size |
|---|---|
| 200 – 350 units | 2kW |
| 350 – 550 units | 3kW |
| 550 – 900 units | 5kW |
| 900 – 1,100 units | 7.5kW |
| 1,100 – 1,400 units | 10kW |
| 1,400+ units | 15kW ya zyada |
Sab se zyada garam mahine (June ya July) ke bill pe size na karein. Is se system zaroorat se zyada bara ho jayega, aur sardiyon mein zyada tar generation waste hogi, jo net billing ke naye rules mein pehle se kam faida mand hai. Average pe size karna hamesha behtar hota hai.
Tareeqa 2: naye ghar ke liye load list bana kar size karein
Agar aap ka ghar naya hai ya abhi bijli ka connection nahi laga, tou bill wala tareeqa kaam nahi aayega. Is soorat mein har appliance ka load likh kar hisaab lagayein.
| Appliance | Approximate load | Roz kitne ghante |
|---|---|---|
| 1.5 ton inverter AC | 1,000 – 1,400W | 6 – 8 ghante |
| Refrigerator | 150 – 250W average | 24 ghante (cycle) |
| Deep freezer | 200 – 300W average | 24 ghante (cycle) |
| Ceiling fans (4) | 60W each | 8 – 10 ghante |
| LED lights (poora ghar) | 100 – 200W | 5 – 6 ghante |
| TV aur electronics | 100 – 150W | 4 – 5 ghante |
| Water pump | 750W | 1 – 2 ghante |
| Washing machine | 300 – 500W | 1 ghanta |
Har appliance ka wattage aur roz kitne ghante chalta hai, dono multiply kar ke daily units (kWh) nikal lein, phir sab jama kar dein. Jo total aaye, usse 4.5 (average daily units per kW) se divide kar dein, aap ko rough kW mil jayega.
Yeh tareeqa bill wale tareeqe se zyada mehnat manga hai, lekin naye ghar ke liye yehi sab se accurate rasta hai.
Plot size ke hisaab se rough andaza
Yeh sirf ek starting point hai, asal decision hamesha bill ya load list se lena chahiye, lekin bohat se log apne ghar ke size se hi andaza lagana chahte hain. Neeche ek rough guide hai jo Pakistan ke aam gharon ke pattern pe mabni hai.
| Ghar ka size | Typical family aur AC load | Suggested system |
|---|---|---|
| 3 – 5 marla | Chota family, 1 AC | 3kW – 5kW |
| 7 – 10 marla | Darmiyana family, 1 – 2 AC | 5kW – 7.5kW |
| 1 kanal | Bara family, 2 – 3 AC | 10kW – 12kW |
| 2 kanal ya farmhouse | Bohat bara load, multiple AC | 15kW – 20kW |
Yaad rahe, do 10 marla ghar ka load bohat mukhtalif ho sakta hai, agar ek mein sirf ek chota AC hai aur doosre mein teen split AC chalte hain. Plot size sirf ek indicator hai, guarantee nahi. Apna asal bill zaroor check karein.
Roof pe kitni jagah chahiye
System size decide karne ke baad, yeh bhi zaroori hai ke aapki chhat pe utni jagah ho.
| System size | Approximate panels (585W) | Roof area chahiye |
|---|---|---|
| 3kW | 5 – 6 | 350 – 420 sq ft |
| 5kW | 8 – 9 | 550 – 650 sq ft |
| 7.5kW | 12 – 13 | 850 – 950 sq ft |
| 10kW | 16 – 17 | 1,000 – 1,150 sq ft |
Yeh area mein walkway aur row spacing bhi shamil hai, taake ek panel ka shadow doosre pe na pare. Panels ko bilkul edge to edge laga dena dekhne mein efficient lagta hai, lekin December mein self-shading ki wajah se output kam kar deta hai.
On-grid ya hybrid, size pe kya farq parta hai
On-grid system ka size sirf aapki daytime consumption ke hisaab se kaafi hai, kyun ke raat ko grid se bijli aati hai. Hybrid system, jisme battery bhi ho, thora bara design kiya jata hai taake battery bhi charge ho sake aur ghar bhi chal sake, khaas kar agar loadshedding aap ke elaqe mein hoti hai.
Agar aap hybrid ki taraf ja rahe hain, inverter ka size bhi is hisaab se select karna zaroori hai. Poori guide hamari hybrid inverter price in Pakistan page pe hai.
AC ka hisaab alag se karein
Ghar ke total load mein sab se bara factor AC hota hai, aur ek chota sa farq, jaise inverter AC vs non-inverter AC, poore system size ko badal deta hai.
1.5 ton inverter AC agar 8 ghante chale tou roughly 6 se 7 units per din leta hai, jabke non-inverter wahi kaam ke liye 10 se 12 units le sakta hai. Agar aap ke ghar mein ek se zyada AC hain, har ek ka hisaab alag se karein aur load list mein jama karein.
1 ton AC ke liye kitne panel chahiye, iska detailed calculation hamari solar panels for 1 ton AC guide mein hai, jo baqi appliances ke sath combine kar ke poora ghar ka size nikalne mein madad degi.
Common ghaltiyan jo log system size karte waqt karte hain
Sirf July ke bill pe size karna. Is se system bara ho jata hai aur November se February tak zyada tar generation waste hoti hai.
Future AC ko bhool jana. Agar aap agle saal ek aur AC lagane wale hain, abhi thora zyada size rakhna behtar hai, taake baad mein poora system dobara na banwana pare.
Inverter ka surge rating check na karna. AC compressor start hote waqt normal se do se teen guna zyada current khenchta hai. Agar inverter sirf running load ke hisaab se select kiya gaya hai, wo surge pe trip kar sakta hai.
Roof shading ignore karna. Water tank ya parapet wall ka shadow ek panel pe pare tou poori string ka output kam ho jata hai. Chhat ko subah 9 baje aur shaam 4 baje dekh kar shadow zaroor check karein.
Net billing size karte waqt zaroor yaad rakhein
9 February 2026 se NEPRA ne net metering khatam kar ke net billing shuru ki hai. Jo bijli aap grid ko bechte hain, wo sirf Rs 8 se Rs 11 per unit milti hai, jabke grid se li gayi bijli full tariff pe milti hai, jo Rs 40 se Rs 60 tak ho sakta hai.
Is ka seedha matlab: system ko itna hi bara banayein ke aapki apni consumption cover ho jaye, usse bohat zyada bara na banayein sirf isliye ke “zyada bijli banegi.” Extra bijli jo aap use nahi kar sakte, wo sasty rate pe export hogi, jo purane net metering jaisa faida mand nahi hai. Sahi size wahi hai jo aap ki asal zaroorat ke qareeb ho.
Mausam ke hisaab se output badalta hai
System size nikalte waqt yeh bhi zehan mein rakhein ke solar system saal bhar ek jaisi bijli nahi banata. Spring (March se May) mein output sab se acha hota hai. Garmiyon (June se August) mein irradiance tou strong hoti hai lekin panel ki apni garmi output ka kuch hissa kam kar deti hai. Sardiyon (December aur January) mein din chote hote hain aur Punjab ke kuch ilaqon mein dhund bhi output ko kaafi kam kar deti hai, kabhi kabhi 30 se 40 percent tak.
Iska matlab yeh hai ke jo system garmiyon mein aapka poora load aasani se cover kar raha ho, wahi sardiyon mein shayad utna cover na kare. Agar aap ka winter load bhi kaafi zyada hai, jaise heater ya geyser chalte hain, tou size karte waqt sirf annual average hi nahi, balke winter ke mahino ka bhi khayal rakhein, warna December mein aapko zyada grid pe depend hona parega.
Ghar bara ho raha ho tou kya karein
Agar aap agle kuch saalon mein ghar mein extension karwane wale hain, ya family barhne wali hai, tou abhi thora headroom rakhna samajhdari hai. Inverter ko thora bara le kar aur structure ko is tarah design kar ke ke baad mein aur panels add ho sakein, aap ko poora system dobara banwane ki zaroorat nahi paregi. Yeh upfront thora zyada cost karta hai, lekin do saal baad poora naya inverter khareedne se kahin sasta parta hai.
Qeemat kitni banegi
System size decide hone ke baad, agla sawal qeemat ka aata hai. Poori per-watt aur per-system pricing hamari solar panel ki qeemat Pakistan 2026 aur solar system ka rate kya hai guides mein di gayi hai, jahan aap size ke hisaab se rough cost dekh sakte hain.
Battery ka rate is guide mein nahi diya gaya, kyun ke lithium rate hafte mein kai dafa change hota hai. Aaj ka confirmed battery rate jaanne ke liye WhatsApp karein 03192070022 par.
BuySolars se sahi size ka system lein
Hum Pakistan bhar mein Tier-1 panels, hybrid inverters aur LiFePO4 batteries nationwide delivery ke sath supply karte hain.
Sab se aasan tareeqa yeh hai: apna pichla bijli bill ya apne ghar ka size WhatsApp pe bhej dein, hum aap ko sahi kW batayenge, na ke aap ko zaroorat se zyada bara system bech dein. Current stock hamari products page pe dekhi ja sakti hai.
Zyada tar chote gharon (3–5 marla, 1 AC) ke liye 3kW se 5kW kaafi hota hai, darmiyane ghar (10 marla, 2 AC) ke liye 5kW se 7.5kW, aur bare ghar (1 kanal, 2–3 AC) ke liye 10kW ya zyada. Sahi size aap ke bijli bill se nikalta hai.
Har appliance ka wattage aur roz ke ghante likh kar daily units nikalein, phir 4.5 se divide kar ke rough kW mil jata hai. Naye gharon ke liye yehi tareeqa istemal hota hai.
Roughly 3kW se 5kW, agar ghar mein ek AC hai aur normal family load hai. Agar do AC hain, size thora upar le jayein.
Roughly 10kW se 12kW, family size aur AC ki tadaad ke hisaab se. Bara ghar aur zyada ACs hon tou 15kW tak bhi ja sakta hai.
Haan. Net billing ke naye rules mein extra bijli sirf Rs 8 se Rs 11 per unit pe bikti hai, jabke aap grid se Rs 40 se Rs 60 per unit khareedte hain. Zaroorat se zyada bara system paisa waste karta hai.
Nahi, AC ko poore ghar ke load mein shamil kar ke ek hi system design karein. Alag AC-only system rakhna aam tor par zaroori nahi hota.
Aakhri baat
Sahi solar system size na zyada bara hai na zyada chota, balke wo hai jo aap ki asal consumption se match kare. Apna 12 mahine ka average bill nikalein, ya naye ghar ke liye load list banayein, roof space confirm karein, aur future AC ka khayal rakhein. Sirf plot size dekh kar decision na karein, wo sirf shuruati andaza hai.
