6 Tips to Make Your Solar Panel Last Long


Solar panels are designed with a limited lifespan. Unlike traditional building materials that can last for generations, solar panels deteriorate over time. Manufacturers indicate their solar panels will last for at least 25 years and usually up to 30 years before showing signs of wear and tear. However, there are ways you can make your solar panel last longer:

1. Clean Your Solar Panels Regularly

Solar panels receive a lot of wear and tear from the environment. They are exposed to heat, dirt, and debris, damaging solar panels over time. Regularly clean off dirt, debris, and grime by sanding off any built-up areas with your hand or a soft-bristled brush. Wipe any remaining dirt or dust with a soft cloth soaked in warm water. Be sure not to use any abrasive materials that may scratch or dent your solar panel. Bam window cleaners can do an excellent job keeping your solar panels clean.

2. Get a Regular Inspection of the Panels

Regularly check the condition of your solar panels so you can detect any problems before they become serious. Regular inspections will allow you to maintain and repair solar panels in time. A professional is best suited to inspect your panels. Review panel components such as junction boxes, ripples, and bends. Also, look for any cracked areas on your panels and weak electrical connections or wires. Have a qualified technician repair or replace the damaged components immediately before they cause damage to your system and cause fires.

3. Shelter Your Panels in Extreme Weather Conditions

Solar panels become vulnerable to extreme weather conditions as they age. In winter, ice and snow can build up on panels and prevent them from absorbing the sun’s energy. If not melted away regularly, ice and snow build-up can damage a solar panel’s surface. During the summer months, when temperatures become unbearable, your panels may overheat, which can cool the efficiency of your solar system for the following months. Shelter your solar panels from extreme weather conditions by using an umbrella or some other structure to block snow or rain from coming into contact with them.

4. Utilize a Backup Battery for Your Solar Panels

Batteries are a source of power that can supply electricity when there is an insufficient amount of sunlight. A battery will keep your solar panels functioning when there’s no sunlight available. You can also use a battery to store energy from the sun during the day so you can use it at night. Keep your batteries in good shape by regularly charging them fully before storing them. Never leave dead batteries connected to solar panels as they will damage the cells in them over time.

5. Seal Any Gaps Around the Edges of Your Solar Panels With Sealant Products

Sealant products can prevent rain, dirt, and grime from building up around the edges of your panels. These build-ups can cause corrosion over time and damage your system. Seal any gaps around the edges of your panels with sealant products to prevent water from coming in contact with them. If you already have a build-up of water or other foreign matter on your solar panel, you will need to remove it before sealing off the panel.

6. Apply a Quality Protective Coating Every Few Years

A quality protective coating will protect the surface of your solar panels against scratches and wear. Applying a quality protective coating to your solar panels seals off the panel’s surface against the effect of moisture and debris. The best time to apply a protective coating is during spring or early fall months when temperatures are warm enough.


Making your solar panels last longer is only a few of the ways you can preserve their functionality. If you follow these tips, you can ensure your solar panels are in prime condition for years to come.
