Getting a solar system installed on your home is a big step—one that can bring big savings on your electricity bill. But many people ask the same question right after installation: “What happens next?” The panels are on the roof, the inverter is blinking, and the sun is shining—but how does it all work together in real life?
In Pakistan, where electricity bills keep going up and power cuts are common, solar offers a smart and stable solution. But Solar System’s First 30 Days after installation are very important. This is when you learn how the system works, how to use your appliances in a better way, and how to check if the system is working properly. It’s also the time when you start seeing your savings grow.
Whether you’ve just installed your first solar system or you’re thinking about getting one, this guide is for you. We’ll keep the language simple, avoid technical talk, and focus on what really happens during the first month of using solar at home. From real savings to common mistakes, we’ll walk you through the full journey—step by step.
What Happens After Installation? A Peek Into Your Solar System’s First 30 Days
In this guide, we will explain what to expect during the first 30 days after installing a solar system, how to track your system’s performance, ways to maximize your savings, common issues you might face, and real examples from homes in Pakistan to help you feel confident using solar energy from day one.
Day 1–3: System Testing and First Power-Up
After the installation is complete, your solar installer will carry out final testing. This is when your solar system is connected to your home’s electrical network and switched on for the first time. The inverter will begin converting sunlight into usable electricity, usually starting its function by 8:30 AM or 9:00 AM once the sun is up. Here is what to expect in these first 3 days:
- The inverter lights will turn on, usually green for normal operation.
- Daily solar generation can be seen through the inverter screen or app.
- Your home will start using electricity generated directly from your solar panels.
- You may still draw power from the grid at night or when usage is high.
- No savings are visible yet, but you’re now using less WAPDA electricity. Keep an eye on your inverter. It should not display error signs. Your installer might do a follow-up check to confirm stable performance.
Day 4–7: Monitoring System Health
Once the system is running, it’s time to understand how to monitor it. Most modern solar systems in Pakistan come with monitoring apps (Growatt, Solis, Huawei, etc.). These apps give you clear data on how many units (kWh) your system generates each day. Here’s what you should start doing:
- Open the monitoring app daily to check solar output.
- Compare daily generation to expected values (e.g., 20-25 kWh for a 5kW system).
- Ensure the inverter doesn’t show fault codes.
- Check that all panels are active and not shaded.
- Record values in a simple notebook if you prefer offline tracking. System health in this week is critical. If any error signs show or the output is low, call your installer immediately. Dust, wiring, or inverter setup errors can reduce performance.
Day 8–10: Figuring Out Your Usage
Now that solar is working properly, it’s time to adjust how you use electricity. Solar systems work best during the day, between 10:00 AM and 4:00 PM. So using appliances during this window will maximize savings. Use this checklist to make smart usage decisions:
- Run washing machines, irons, and water pumps during sunlight hours.
- Avoid using heavy appliances at night when solar is not active.
- Keep track of your high-usage devices like ACs or geysers.
- If you have timers, schedule appliances for midday.
- Try to spread out usage evenly to avoid high loads. Doing this will reduce the units you pull from WAPDA and increase the use of free solar energy. You’ll start seeing the real benefit here.
Day 11–14: Net Metering Kicks In
If you opted for net metering, this is the time it typically becomes active. Your solar provider submits documents to NEPRA and DISCO (like LESCO, IESCO) right after installation. It takes 10–15 days for the approval. Here’s how net metering works:
- When your solar generates more than you use, the extra power goes to the grid.
- That exported power is shown as credit on your electricity bill.
- These credits reduce your monthly charges. Keep in mind:
- Net meters display both import (grid usage) and export (solar sent to grid).
- You can export during peak daylight hours, so keep usage slightly below generation.
- Monitor your export through your meter or app. Net metering makes solar more financially valuable. Without it, extra power is wasted.
Day 15–20: Checking Bill Impact
Mid-month is a good time to start seeing how much your bill is reducing. You won’t see the full bill yet, but you can notice changes in meter readings. To assess impact:
- Check how many units your WAPDA meter shows for the month.
- Compare it to last month’s usage for the same days.
- Estimate savings based on reduced grid consumption.
Example Comparison Table:
| Item | Before Solar | After Solar |
|---|---|---|
| Daily WAPDA Units | 28 units | 7 units |
| Daily Solar Units | 0 units | 21 units |
| Bill Estimate | Rs. 18,000 | Rs. 4,500 |
Your actual bill will confirm the change, but this daily tracking shows that the system is delivering results.
Day 21–25: Fixing Small Issues
now, you’ll notice some small maintenance needs or performance drops. That’s normal. A solar system has few moving parts, but it still needs some care. Common issues and how to fix them:
- Dust on Panels: Clean panels every 10–15 days with soft water and cloth.
- App not working: Reconnect Wi-Fi or update the app.
- Wiring Loose: Call your installer if output drops suddenly.
- Inverter Errors: Look up the error code in your manual or ask your provider. List of regular maintenance tasks:
- Panel cleaning
- Inverter app check
- Meter reading check
- Performance logging Doing these helps keep your system in top condition.
Day 26–30: Confidence Grows
In the final week of the first month, you will have gained confidence in using and maintaining your solar system. You’ll know when your system works best and how to manage your home’s energy better. Key habits by now:
- Using major appliances during solar hours
- Monitoring the system every 2 days
- Tracking bills and meter readings
- Cleaning panels twice a month Also, you can:
- Think about adding batteries if you face frequent load-shedding
- Suggest solar to relatives and friends
- Plan for expansion if your load increases By the 30th day, your system should feel like a regular part of your home. You’re no longer just a buyer—you’re an informed solar user.

FAQs: Solar System’s First 30 Days in Pakistan
Q1: Why is my solar output low on cloudy days? Solar production drops by 20-40% during cloudy weather. That’s normal. Try to shift usage to sunnier days if possible.
Q2: Can I turn off my solar system? It’s not recommended. Solar inverters are automatic and will turn off themselves at night. Let the system run on its own.
Q3: What if my net meter isn’t active yet? Until it’s active, you won’t get credit for excess power. Use more power during the day to avoid wastage.
Q4: How often should I clean the panels? Every 10–15 days, or sooner after dust storms.
Q5: Can I increase my solar capacity later? Yes, if your inverter allows it and you stay within the net metering limit (typically 15kW residential).
