क्या आपकी छत सोलर के लिए तैयार है? MYSUN की 6-स्टेप गाइड से जानें

भारत में सोलर एनर्जी सिर्फ एक पर्यावरण अनुकूल विकल्प नहीं रही—अब ये घरों को बिजली संकट से राहत देने वाला व्यावहारिक समाधान बन चुकी है। लेकिन सवाल है,क्या आपका घर सोलर सिस्टम लगाने के लिए उपयुक्त है?

इस लेख में हम बताएंगे कि किन 6 जरूरी पहलुओं पर ध्यान देकर आप यह तय कर सकते हैं कि सोलर इंस्टालेशन आपके लिए सही कदम है या नहीं।

छत की मजबूती और धूप की उपलब्धता

हर छत सोलर के लिए नहीं बनी होती।
आपको ये जानना जरूरी है कि:

• क्या आपकी छत में कहीं से पानी टपकता है, दरार है या वह पुरानी और कमजोर हो गई है?
• क्या वह अगले 25 वर्षों तक बिना बड़ी मरम्मत के टिक सकती है?
  

इसके साथ ही, सोलर के लिए सबसे जरूरी है धूप:

• आपकी छत को रोजाना कम से कम 5–6 घंटे की सीधी धूप मिलनी चाहिए।
  
• दक्षिण दिशा वाली छत सबसे बेहतर मानी जाती है, लेकिन अच्छे डिजाइन के साथ पूर्व-पश्चिम भी काम करते हैं।
  

आपके पास कितनी खाली छत है?

सोलर लगाना जगह की माँग करता है।
1 किलोवाट (kW) के सिस्टम के लिए आपको लगभग 80 वर्ग फुट खुली जगह चाहिए।

ध्यान दें:

• छत पर बने वाटर टैंक, डिश एंटीना या किसी भी छाया देने वाले अवरोध को हटाना या उसका हल निकालना ज़रूरी होगा।
  

आपकी बिजली की खपत क्या कहती है?

बिजली बिल ही आपकी सोलर ज़रूरतों का नक्शा होते हैं।
आपको यह करना है:

• पिछले 12 महीनों के बिजली बिल को देखें और औसत यूनिट निकालें।
  
• उदाहरण: यदि मासिक औसत 300 यूनिट है, तो करीब 3–4 kW की प्रणाली पर्याप्त होगी।
  

अगर आप भविष्य में EV चार्जर, हीटर या एयर कंडीशनर जोड़ने की सोच रहे हैं, तो अभी से सिस्टम को उसी अनुसार डिजाइन करें।

क्या आपने सब्सिडी और लागत की प्लानिंग की है?

सोलर को अफोर्डेबल बनाने के लिए भारत सरकार कई योजनाएं चला रही है:

• PM Surya Ghar Yojana जैसे कार्यक्रमों के तहत ₹1,08,000 तक की सब्सिडी मिल सकती है।
  
• कुछ राज्यों में हर महीने 300 यूनिट तक मुफ्त बिजली का भी लाभ मिलता है।
  

साथ ही, MYSUN देता है:

• आसान EMI विकल्प
  
• सोलर लोन
  
• और ऑन-द-स्पॉट अप्रूवल की सुविधा
  

MYSUN का प्रस्ताव सभी आवश्यक खर्च जैसे ग्राउंडिंग, सर्किट बोर्ड अपग्रेड आदि को पहले से शामिल करता है—कोई छुपा खर्च नहीं।

क्या आपने स्थानीय नियमों और DISCOM प्रक्रियाओं को समझा?

नेट मीटरिंग, इंस्टॉलेशन परमिशन, और DISCOM की मंज़ूरी जैसे पहलुओं को अक्सर लोग नजरअंदाज कर देते हैं।

लेकिन ये बेहद जरूरी हैं:

• नेट मीटरिंग से आप ग्रिड को एक्स्ट्रा बिजली बेच सकते हैं और बिल में क्रेडिट पा सकते हैं।
  
• DISCOM द्वारा स्ट्रक्चरल और सेफ्टी अप्रूवल लिया जाता है।
  

MYSUN इन सभी प्रक्रियाओं को आपके लिए आसान बना देता है—डॉक्युमेंटेशन से लेकर अप्रूवल तक।

क्या आपने सही सोलर इंस्टॉलर चुना है?

सोलर इंस्टॉलेशन एक बार का निवेश है—इसलिए गलत इंस्टॉलर चुनना महंगा पड़ सकता है।

आपको देखना चाहिए कि:

• इंस्टॉलर MNRE द्वारा रजिस्टर्ड है या नहीं
  
• क्या वे BIS स्टैंडर्ड्स का पालन करते हैं?
  
• क्या उनके पास प्रामाणिक ग्राहक रिव्यू और प्रोजेक्ट अनुभव है?
  
  

अब क्या करें?

अगर आप ऊपर दिए गए अधिकतर बिंदुओं में फिट बैठते हैं, तो अब समय है एक्शन लेने का:

Switching to solar energy is a smart move—but only if it's done right. Whether you're a homeowner looking to cut electricity bills, or someone researching how to install solar panels in India, knowing what not to do is just as important as knowing what to do.

This guide answers common questions like:

• “What should I check before installing solar panels?”
  
• “Why are my solar panels underperforming?”
  
• “What permits or loans do I need before going solar?”
  

Let’s explore the top 7 solar installation mistakes—and how to avoid them with pro tips from MYSUN.

1. Not Doing Enough Research Before Installation

Problem: Many homeowners jump into buying solar without understanding the basics, which leads to poor system performance or inflated costs.

Why This Matters:

• Mismatched systems: Choosing the wrong capacity can lead to power shortages or wasted money.
  
• Poor installer choice: Unqualified contractors may cut corners or use subpar materials.
  

Pro Tip from MYSUN:

• Compare panel types (monocrystalline vs. polycrystalline vs. thin-film).
  
• Understand your home’s energy consumption and solar potential.
  
• Check the installer's reputation through reviews, certifications (MNRE-approved), and completed projects.

2. Choosing the Wrong Type of Solar Panel

Problem: People often choose solar panels without understanding the differences, resulting in poor performance, wasted investment, and space constraints

Know Panels Types:

• Monocrystalline – High efficiency, ideal for limited roof space, higher cost.
  
• Polycrystalline – Balanced option for most homes, cost-effective.
  
• Thin-Film – Flexible and lightweight but lower output; suited for shaded areas or industrial roofs.
  

Mistakes to Avoid:

• Prioritizing cost over efficiency in compact spaces.
• Ignoring local climate (e.g., thin-film works better in diffused sunlight).
  
• Overlooking aesthetics in housing societies or gated communities.
  

Pro Tip from MYSUN: Choose based on your roof size, sunlight hours, and energy demand—not just price tags.

3. Incorrect Placement and Positioning

Problem: Improper panel placement = low energy output = poor ROI.

How to Maximize Solar Output:

• Direction: Face panels south (in India) for maximum sunlight.
  
• Tilt angle: Adjust for your latitude—Delhi (28°), Mumbai (19°), etc.
  
• Avoid shade: Trees, buildings, water tanks—shade cuts output drastically.
  

Pro Tip from MYSUN:

• Observe Sunlight Patterns: Spend 10–15 minutes on your rooftop during morning, noon, and late afternoon to note where sunlight falls.
  
• Use a Compass App to Check South Direction: Use Google Maps or a built-in compass on your phone to align panels correctly.
  
• Sketch a Simple Rooftop Layout: Draw your rooftop and mark fixed structures like tanks or walls to visually plan your panel layout.
  
• Consult a Trusted Installer Like MYSUN: Instead of using software, Solar professionals can suggest the right angle based on your city.

4. Underestimating Your Energy Needs

Problem: If your system is too small, you’ll still rely on the grid. Too large, and you’ll overinvest without maximizing returns.

How to Estimate Correctly:

• Check the past 12 months’ electricity bills.
  
• Factor in future appliances (e.g. EVs, ACs, geysers).
  
• Use the MYSUN Solar Calculator as per your needs—whether it's for a residential property or a commercial setup—and get a free, customized solar assessment.
  

Common Mistake:

• Assuming one-size-fits-all. A 3BHK home with 2 ACs needs a different setup than a 1BHK without them.

Pro Tip from MYSUN:

Oversizing without subsidy approval could void net metering eligibility in some states.

5. Not Planning Roof Repairs Before Installation

Problem: If your roof needs repair later, you’ll pay twice—once for dismantling the panels, and again for reinstallation.

What to Inspect Beforehand:

• Age of roof: If over 15 years old, consider re-roofing first.
  
• Structural strength: Ensure it can bear solar load + wind forces.

Pro Tip from MYSUN:

MYSUN conducts a pre-installation roof audit to prevent such future costs.

6. Ignoring Solar Loan & Financing Options

Problem: Many homeowners don’t know they can finance solar—so they delay installation or use high-interest personal loans.

Best Solar Financing Options in India:

• Easy Financing Options: Pay in easy monthly installments (EMIs).
• Government Subsidies and Incentives: Central and state-level programs offer financial support and subsidies for residential solar systems.
• Tax Benefits: Loans for solar often come with tax advantages, helping you save even more.

Pro Tip from MYSUN:

Why should you wait for when you can install it today with a loan.

What is Net Metering?

Net Metering is an innovative billing policy that allows solar power system owners to send excess electricity generated by their solar panels back to the local electricity grid. In return, they receive credits on their electricity bill, effectively reducing or even eliminating their monthly charges.

In simple terms:
When your rooftop solar system generates more electricity than you use, the extra units are exported to the grid, and your electricity provider reduces your bill accordingly.

How Does Net Metering Work?

1. Solar Power Generation
   Your solar system generates electricity during the day using sunlight.
   
2. Real-Time Consumption
   This electricity powers your home or business appliances.
   
3. Export to Grid
   If you produce more than you consume, the extra electricity is exported to the local grid.
   
4. Import When Needed
   At night or during cloudy weather, when solar isn't generating enough, you can draw electricity back from the grid.
   
5. Monthly Bill Adjustment
   Your energy provider uses a bi-directional meter (also known as a net meter) to meticulously track both the electricity you import from the grid and the electricity you export to it.

• Your Electricity Bill = Units Imported – Units Exported
• This means if your exports exceed your imports, your bill could be zero, or you might even accumulate credits for future use.

Key Benefits of Net Metering

1. Lower Electricity Bills

• Drastically reduce monthly power bills
  
• In some cases, pay nothing at all
  

2. Faster ROI on Solar Investment

• Higher savings = quicker return on your solar investment
  

3. Efficient Use of Solar Power

• No solar energy goes to waste, even during low consumption periods
  

4. Energy Independence

• You rely less on the grid, and have control over your electricity
  

5. Eco-Friendly Impact

• Exporting clean energy reduces the carbon footprint of your entire neighborhood

यह लेख किनके लिए है?

• घर या बिज़नेस पर सोलर पैनल लगवाने की सोच रहे लोग
  
• नए सोलर यूज़र्स जिन्हें मानसून में परफॉर्मेंस को लेकर सवाल हैं
  
• सोलर सिस्टम में निवेश करने वाले ग्राहक जो जानना चाहते हैं कि क्या बारिश में बिजली बनेगी
  

सबसे आम सवाल: बारिश में सोलर पैनल बिजली बनाते हैं या नहीं?

हां, सोलर पैनल बारिश में भी काम करते हैं।
हालांकि उनकी आउटपुट क्षमता थोड़ी कम हो सकती है, लेकिन बिजली बनना पूरी तरह बंद नहीं होता।

कैसे काम करते हैं सोलर पैनल बारिश में?

सोलर पैनल सूरज की रोशनी (light) से बिजली बनाते हैं, ना कि गर्मी (heat) से।
इसलिए जब आसमान में बादल होते हैं या हल्की बारिश हो रही होती है, तब भी कुछ रोशनी ज़रूर धरती तक पहुंचती है — इसे कहते हैं diffused sunlight।

बारिश में सोलर आउटपुट कितना होता है?

• औसतन 10% से 25% तक आउटपुट मिलता है
  
• सिस्टम पूरी तरह बंद नहीं होता, बल्कि न्यूनतम स्तर पर काम करता है
  

मानसून में सोलर सिस्टम के फायदे

1. नेचुरल क्लीनिंग

• बारिश सोलर पैनल पर जमी धूल, मिट्टी और पत्तों को धो देती है
  
• साफ पैनल = बेहतर सनलाइट एक्सपोज़र = बेहतर परफॉर्मेंस
  

2. कम मेंटेनेंस

• नियमित मैन्युअल सफाई की ज़रूरत घट जाती है
  
• मेंटेनेंस कॉस्ट में कटौती
  

3. बेहतर लॉन्ग टर्म आउटपुट

• नियमित सफाई से पैनल्स की एफिशिएंसी बनी रहती है
  
• लंबी उम्र तक मजबूत परफॉर्मेंस
  

अगर लगातार बादल हों तो क्या?

जब 2-3 दिन तक सूरज न निकले:

• बिजली प्रोडक्शन कम होगा, लेकिन सिस्टम पूरी तरह बंद नहीं होता
  
• Net Metering या Battery Backup जैसे सॉल्यूशन्स की मदद से आप आराम से बिजली चला सकते हैं
  

मानसून में सोलर सिस्टम इंस्टॉलेशन के स्मार्ट टिप्स

1. सही एंगल सेट करें
   पानी बहाव के लिए टाइल्टेड इंस्टॉलेशन जरूरी है
   
2. वॉटरप्रूफिंग ज़रूरी है
   वायरिंग और जंक्शन बॉक्स को अच्छी तरह सील कराएं
   
3. रियल टाइम मॉनिटरिंग
   जैसे MYSUN का Smart Analytics सिस्टम – आउटपुट हर समय ट्रैक करें
   
4. बैटरी स्टोरेज में निवेश करें
   बादलों और रात में बिजली उपयोग के लिए जरूरी
   

क्या मानसून में सोलर लगवाना सही है?

बिलकुल! मानसून में सोलर इंस्टॉलेशन करना न सिर्फ संभव है, बल्कि कई बार फायदेमंद भी होता है।

क्यों?

• गर्मियों की ज्यादा डिमांड के मुकाबले मानसून में कम डिमांड के चलते इंस्टॉलेशन जल्दी और शांति से हो जाता है
  
• बारिश पैनल को नेचुरली धोकर उसे बेहतर स्टार्ट देती है
  
• मानसून के बाद, तुरंत फुल आउटपुट मिलने लगता है
  

MYSUN क्यों चुनें?

MYSUN एक भरोसेमंद और अनुभवी सोलर कंपनी है जो पूरे NCR और उत्तर भारत में सोलर सॉल्यूशन्स उपलब्ध कराती है।
चाहे गर्मी हो, बादल हों या बारिश, MYSUN देता है एक ऐसा सोलर सिस्टम जो हर मौसम में परफॉर्म करे।

MYSUN की ख़ासियत:

• मौसम-प्रूफ इंस्टॉलेशन
  
• स्मार्ट मॉनिटरिंग और बैकअप सॉल्यूशन्स
  
• इंस्टॉलेशन के बाद भी एक्टिव सपोर्ट और मेंटेनेंस
  

निष्कर्ष: क्या बारिश में सोलर पैनल काम करते हैं?

✅ हां, करते हैं
⚡ आउटपुट थोड़ा कम होता है (10–25%), लेकिन बंद नहीं होता
🌧️ बारिश पैनल्स की सफाई करके उनकी क्षमता को बढ़ा देती है
🔋 बैटरी और नेट मीटरिंग से आप मानसून में भी बिना रुकावट बिजली का उपयोग कर सकते हैंआपके सोलर सवालों का भरोसेमंद जवाब – MYSUN

If you're a homeowner in Noida and you're concerned about rising electricity bills, frequent power cuts, or long-term sustainability, you're likely wondering: Are solar panels a reliable solution for my home?

Short Answer: Yes. With Noida's abundant sunlight, government subsidies, and modern solar technologies, solar panels are one of the most dependable and cost-effective upgrades you can make for your home—especially when installed by experienced providers like MYSUN.

Why Solar Panels Are a Smart and Reliable Choice in Noida

1. Consistent Performance in Noida’s Climate
Noida gets over 300 sunny days a year. Even during the monsoon season or cloudy days, solar panels continue to generate electricity—just at slightly reduced output.

2. Long-Term Durability with Minimal Maintenance
Modern solar panels have no moving parts, reducing wear and tear. They’re built to last 25+ years with minimal maintenance like occasional cleaning and yearly inspections.

3. Government Subsidies Make It Affordable
Through the PM Surya Ghar Muft Bijli Yojana, Noida homeowners can avail up to ₹1,08,000 in subsidies:

• ₹78,000 from the central government
  
• ₹30,000 from the Uttar Pradesh government
  This dramatically lowers the upfront cost of going solar.
  

4. Built for Noida’s Urban Rooftops
With limited space, many Noida homes need high-efficiency solar panels that generate maximum power per square foot. Brands offered by MYSUN are engineered specifically for these urban requirements.

How Do Solar Panels Actually Work?

Solar panels use photovoltaic (PV) cells to convert sunlight into electricity. These cells:

• Work without moving parts (reducing failure risk)
  
• Perform well even in warm or humid conditions
  
• Are ideal for regions like Noida with hot summers and seasonal dust
  

 What Makes a Solar Panel Truly Reliable?

When MYSUN recommends a panel, it’s based on:

• Efficiency rating (typically 15% to 22%)
  
• Temperature coefficient (how panels perform in extreme heat)
  
• Build quality (tempered glass, anodized aluminum frames)
  
• Brand trust and warranty (usually 25 years or more)
  
• After-sales support, including AMC and mobile app monitoring
  

Real-World Reliability: Common Questions Answered

Q: Do solar panels stop working when it rains?
A: No. They still produce electricity, though at reduced output.

Q: Will my solar system work during power cuts?
A: Yes—if you choose a hybrid or off-grid system with battery backup, you can run essential appliances even during outages.
