Here are the honest lessons we’ve learned while helping others fix their solar setups.

Read these carefully. They’ll save you money, time, and hassle.

Skipping the site check

When people rush, they often skip properly checking the roof before installing panels.

• If the roof is cracked or old, it can get worse later
• Shade from trees or a water tank can cut your solar output significantly

Always start with a full roof check and sunlight study before installing solar. 

Trust me, that one step pays off later.

Wrong panel direction and tilt

Panels must face the right direction in India (south) and have the correct angle (about 15 to 30 degrees).

1. In one case, panels were just installed flat to save time. The owner wondered why generation stayed low.

Solar isn’t just about panels, it's about how they’re placed too.

Weak mounting and cheap materials

During a recent storm in Indore, lots of panels came off rooftops. 

Not because they were old, because the mounting was cheap and not built for real weather.

•  Choose strong, weather-safe mounts, even if they cost a bit more
•  Ask about wind rating of mounts (should handle at least 120 km/h in many places)

Spending a little extra on structure now saves you a big scare later.

Picking low-quality parts

Some installers cut corners with low-cost panels or inverters.

•  Early solar users in Gujarat saw their panels fail in 8–12 years instead of the promised 25. 

Many had cracks or got damaged easily. 

That’s not normal wear and tear.

•  Cheap inverters and wrong wires can lead to breakdowns and even fire risks.

Go only with trusted brands and make sure you get quality components. 

It’s not extra, it’s essential.

Poor wiring and electrical safety

Messy wiring or wrong cable sizes are not just risks, they affect efficiency too.

•  Wires exposed on the roof can get damaged by wind or rain.
•  Loose connections can lead to energy loss, even safety risks. 

Ask your installer to organize cables cleanly and use safe connectors. 

Don’t settle for tangled mess.

Not accounting for future needs

One family added solar with no thought for future upgrades. 

Next year, they bought an EV, but the solar setup couldn’t support it.

If you plan to add an EV or grow your home/family, let that be part of your initial planning.

DIY repairs gone bad

Some homeowners try to fix panels themselves. Bad idea.

If something breaks, call professionals. 

Serious electrical work must be done safely.

No monitoring system in place

Solar panels silently produce power, but if the system fails, you might not notice unless you're watching.

Forgetting maintenance

Panels look set-and-forget, but dust, bird droppings, and grime eat away up to 30% of solar efficiency in dusty areas. 

•  Clean panels every few weeks, or more if your area is dusty. 

It matters. Better output, better savings.

•  In case you don’t want to clean yourself, get a cleaning plan in place.

Ignoring local rules and net metering

Some owners start solar but never get it approved by local power companies. 

Then they don’t get credits for extra solar power.

That extra energy disappears into the grid and they lose the benefit.

Make sure the installer applies for net metering or grid approval from the DISCOM, so the extra juice comes back to you.

A quick recap of lessons

•  Don’t skip site checks
•  Get direction and tilt right
•  Value strong mounts, especially in storm-prone areas
•  Buy quality, not the cheapest
• Keep wiring clean and safe
•  Plan for future growth
•  No DIY for serious repairs
• Use monitoring tools
•  Clean panels regularly
•  Don’t ignore net metering

Solar is a great investment, but only if done right.

Learn from other people’s mistakes and build your system to last 20-plus years. Spend small time on planning now, save years of electricity bills and stress later.
