Check Your Roof First

Before buying any solar kit, take a good look at your roof:

• Is the roofing material in good shape?
  
• Are the rafters and decking solid?
  
• Do you have any old vents or leak spots?
  
• Is the area easy to access now and later for maintenance?
  

Is Your Home a Good Fit for Solar?

Use tools like Google Project Sunroof or PVWatts to find out if your home gets enough sunlight. Look out for:

• Trees or buildings that cast shade during different times of day
  
• Roof space that faces south or west for best output
  
• Any nearby trees that could grow and block sun in the future
  

Check Your Electrical Setup

You’ll want to be sure your electrical system can handle solar. Look into:

• Your current panel’s capacity
  
• Where you’ll put disconnect switches and monitoring gear
  
• How you’ll run wiring from roof to ground
  
• Whether your setup needs an upgrade
  

Pick the Right Season to Install

The best times to install are:

• Spring or fall – Mild weather and safer working temps
  Avoid extreme summer heat (can burn your hands on the roof) and winter snow/ice (slippery and limited daylight).
  On install days, start early to beat the heat and avoid working during windy or rainy conditions.
  

Avoid These Common Wiring Mistakes

We’ve seen a few issues pop up again and again:

DC Side:

• Don’t mix different panel types

Common DIY Solar Mistakes and How to Avoid Them

Installing solar panels yourself can be rewarding but only if you avoid some of the biggest pitfalls we’ve seen firsthand. Here’s what to watch out for:

Mounting Panels the Wrong Way

Improper roof mounting leads to structural issues and leaks down the road.

• Always anchor mounts into rafters, not just the roof decking
  
• Use the right screws long and rated for structural use
  
• Don’t overdrive screws into wood
  
• Apply roof sealant generously and use outdoor-rated types
  
• Flashing should overlap properly and leave room for thermal expansion
  
• Keep rail spacing correct and don’t mix hardware from different brands
  
• Cover all rail ends and secure your cables—don’t let them rub on sharp edges
  

Wiring Errors Are More Common Than You’d Think

Bad electrical connections can lower performance, or worse, become safety risks.

DC Side:

• Know whether your system should be wired in series or parallel
  
• Use matching connectors from the same brand
  
• Weatherproof all junctions
  
• Make sure the wire gauge is thick enough
  
• Anchor wires well so wind can’t yank on them
  

AC Side:

• Ground everything properly
  
• Place disconnect switches where they’re easy to reach
  
• Match breaker sizes to your system specs
  
• Clearly label all circuits
  
• Always follow local code every town’s rules are a bit different
  

Don’t Skimp on Weather Protection

Solar gear lives outside. Sloppy waterproofing is one of the top causes of long-term failure.

• Panels should shed water, not trap it
  
• Leave room beneath them to avoid debris buildup
  
• Allow for thermal expansion in mounts and rails
  
• Use proper sealing at all cable entry points
  
• Mount junction boxes and equipment off the ground
  
• Use outdoor-rated components even for things like enclosures and conduits
  

Sizing Your System Wrong

Getting the size right matters more than you might think.

Too big?

• You’ll spend more upfront and possibly produce more than your batteries or utility allows
  
• Unused energy = wasted money
  

Too small?

• You won’t meet your energy needs
  
• Batteries may undercharge, reducing their lifespan
  
• It’s hard to expand if you didn’t plan ahead
  
• You’ll end up disappointed in the system
  

Ignoring Permits Can Get Expensive

Yes, even DIY solar needs permits in most areas.

• Don’t assume you’re exempt many states require permits for any electrical work
  
• Inform your utility before connecting a system to the grid
  
• Skipping permits can void insurance, delay home sales, or lead to fines
  
• No inspection means no guarantee the system is safe
  

Taking your time to get these details right will make sure your solar setup is safe, legal, and built to last. Don’t learn the hard way plan ahead and do it right the first time.
