Homeowners who have solar panels can have a hard time in winter. Although solar panels are made to withstand tough weather, the accumulation of snow can greatly impair the production of energy. Snow removal should be efficient and safe to ensure maximum performance. This guide will provide practical solutions in the removal of snow on solar systems without destroying them.
Why Removing Snow from Solar Panels is Important
Panels with snow on them generate little or no electricity. A snowfall of even a few inches may shield off the sun.
Frequent snow removal will guarantee:
Constant energy supply – Makes your solar system efficient even during the winter season
Damage prevention – Accumulation of heavy snow may subject the panel frames or mounting systems to stress
Maximization of ROI – Solar panels are very expensive, and it is important to have them clear so as to maximize returns
Safety First: Precautions Before Clearing Snow
Safety must be of primary concern before you decide to remove snow. The process of snow removal may be hazardous because of slippery roofs and electric equipment.
Key Safety Tips:
Avoid climbing on the roof if possible- Select tools that can reach the panels at ground level.
Switch off the solar system- See the manual of your solar panels.
Wear proper shoes- Non-slip shoes should be used to avoid falling on the ice.
Work with insulated tools- Make sure you avoid electrical shock.
Consider professional help- When your panels cannot be easily accessed, or when there is a lot of snow, it is the best to have professional’s help.
Tools for Removing Snow from Solar Panels
The appropriate selection of tools simplifies the process of snow removal and increases safety. Do not use metal shovels or sharp objects that will scratch the panels.
Recommended Tools:
Roof rake using a soft brush – These rakes can be extended to access the snow from the ground.
Soft-bristle broom – Should be used on small panels or light snow.
Snow blower – It should not harm the solar panels.
Leaf blower – Unbelievably useful in light, powdery snow.
Techniques for Safe Snow Removal
Solar panels can be cleared of snow in several effective ways that do not create the risk of damage.
Use a Roof Rake
The safest to homeowners is a roof rake.
- Working from outside the house, push the snow down from the roof.
- Do not scrape; use the gravity to move the snow.
- Apply long and slow strokes to avoid bending panel frames.
Soft-Bristle Broom
A broom is good on smaller boards or light snow.
- Move towards the panel slope.
- Use caution not to press too hard so you don’t scratch the glass.
- This is to be used on powdery snow and not ice.
Leaf Blower for Light Snow
For fluffy, powdery snow:
- Switch on the leaf blower at a medium speed.
- Direct panel surface air.
- This is best-suited for hard-to-reach rooftops.
Allow Snow to Melt Naturally
Inaction is sometimes the most appropriate thing to do:
- Solar panels absorb heat and this tends to melt the snow off the surface.
- Make sure that the panels are angled so that the snow slides off.
- This approach is the most secure, but it is slower.
Avoiding Common Mistakes
Most homeowners end up breaking their panels as they attempt to clear the snow.
Common Errors to Avoid:
Using metal shovels – Can scratch or crack the panels
Ice roof climbing – There is a high risk of injury and damage of panels
Heat water – Glass can be broken
Working with abrasive tools – Do not use wire brushes or heavy scrapers
How to Prevent Snow Buildup on Solar Panels
Prevention is often easier than removal; several strategies can help minimize snow accumulation:
Proper Panel Angle
The panels that are mounted at a steeper angle shed the snow naturally. Most panels are positioned between 30-45 degrees to ensure optimal shedding of snow in winter.
Anti-Snow Coatings
Other panels are hydrophobic, and therefore, the snow does not stick to them easily. Ask your manufacturer whether your panels can do this.
Heated Systems
Homeowners can also look at heating elements that are able to melt snow in regions with heavy snowfall. These are available more often in commercial installations but can work on residential panels.
Regular Maintenance
Inspect panels before winter:
- Take away debris such as leaves or dust.
- Make sure that panel frames are in place.
- Maintenance minimizes chances of damage by snow.
When to Call a Professional
When there is a lot of snow on the ground and your roofs are steep, or you are not very mobile, then you should hire someone to remove the snow.
Professionals have:
- Special equipment such as telescoping brushes or vacuum
- Experience working safely on roofs
- Experience on how to work carefully with panels and to not nullify warranties
Calling professionals can potentially save time, stress, and avoid expensive accidents.
DIY Snow Removal Schedule
Keeping a regular schedule helps maintain efficiency:
After each snowfall over 2 inches – Check whether panels are covered.
In heavy snows – Wait a day to get snow to fall naturally before you remove it.
End of winter – Clean and check panels before spring to give them the best service.
