Switching to solar sounds simple, but here’s the thing: the performance of your system depends less on the panels themselves and more on how well they’re installed. A solar installation mistake during installation can cost you years of lost savings. Most beginners don’t realize this until something goes wrong.
Let’s break down the mistakes people make and the smarter way to avoid them.
Here are the common solar installation mistakes people make.
Most beginners assume that installing solar is just about buying panels and putting them on the roof. The reality is very different. Small decisions like choosing the wrong inverter, ignoring roof condition, or placing panels in shaded spots can cut your system’s performance by a huge margin. Understanding these mistakes early helps you avoid unnecessary costs and get the best output from your solar setup.
1. Choosing Panels Based Only on Price
A lot of homeowners compare solar panels like they compare phone covers: whichever is cheaper wins. That usually leads to weak performance, faster degradation, and higher long-term costs.
Avoid this:
Compare efficiency, warranty, durability, and service quality. A trusted installer like Unisun ensures the right panel type for your roof and climate, not just the cheapest option.
2. Ignoring Roof Condition
Many people install panels without checking whether the roof can handle the structure. A cracked, weak, or old roof means trouble later: leaks, panel shifting, or repairs after installation.
What to do instead:
Get a basic roof inspection before installation. Fix minor issues first so your solar system stays stable for the next 20–25 years.
3. Wrong Panel Placement
If solar panels face the wrong direction or sit under a neighbour’s tree shadow, your system loses a huge chunk of power. Beginners often assume sunlight is equal everywhere, it isn’t.
How to avoid it:
Panels should ideally face south in India with minimal shading. Unisun’s engineers check your site and plan tilt, angle, and placement for maximum output.
4. Poor Quality Wiring and Components
People rarely notice wiring quality until something burns, trips, or stops working. Low-grade cables, connectors, and inverters are silent killers in solar setups.
Smart fix:
Ask your installer about cable ratings, inverter brand, connectors, and surge protection. High-quality components keep your system safe, efficient, and long-lasting.
5. Skipping Load Analysis
Installing a random system size without checking your actual power usage leads to two extremes:
• a system too small to cover your needs
• an oversized system that wastes money
Better approach:
Get a proper load analysis. Unisun calculates your average consumption, future needs, and local weather patterns to recommend the right system size.
6. Not Checking Installer Credentials
A polished social media page doesn’t prove installation quality. Many customers end up with loose mounts, faulty wiring, or incorrect panel orientation because they chose the wrong installer.
Avoid this trap:
Check experience, certifications, customer reviews, service response time, and system warranty. Unisun provides experienced engineers, on-site supervision, and long-term support.
7. Forgetting Maintenance After Installation
Solar is low-maintenance, not no-maintenance. Dust, bird droppings, and seasonal weather changes can bring down your system’s output.
Solution:
A quick cleaning schedule and annual maintenance check will keep your generation high. Unisun offers AMC plans and remote monitoring tools so you can track your system anytime.
