Some of the most common solar panel installation issues include improper mounting, incorrect wiring, inadequate sunlight exposure, and suboptimal angle orientation. These can lead to reduced energy efficiency, wasted solar generation, and potential damage to the panels or your property. However, don't feel disheartened; many of these issues can be avoided or resolved by following proper procedures and seeking expert guidance.

In this article, we'll address each of these common installation issues and offer practical solutions to help you overcome them. By incorporating these tips into your installation process, there's no stopping you from enjoying a seamless solar power experience.

Stay with us as we dive into detail on each common solar panel installation issue and how to effectively resolve them. Remember, knowledge is vital in ensuring your solar array is installed efficiently and effectively - so let's get started!

Common Issues Faced in Solar Panel Installations and Their Solution

Issue #1: Improper Mounting

The first issue that can lead to complications in your solar panel installation is improper mounting. Mounting systems are crucial to securing your panels on the roof and ensuring their stability. Substandard mounting can lead to solar panels being damaged during extreme weather conditions or failing to perform efficiently.

To avoid this issue, it is essential to choose the right mounting system designed specifically for your type of roof and the local weather conditions. Consult with a solar panel installation expert or your manufacturer for recommendations on the most suitable mounting system. Moreover, good-quality mounting systems often come with warranties, which can save you the hassle of dealing with poor installations and the potential damage they can cause.

Issue #2: Incorrect Wiring

Another common issue faced during solar panel installations is incorrectly connecting the electrical wiring. Solar power systems typically require Direct Current (DC) wiring, which is connected directly to an inverter that converts DC power into Alternating Current (AC) suitable for use in households or business premises. Incorrect wiring can lead to the system failing to perform optimally and may also pose safety hazards.

The best way to counter this issue is to be well-educated on the distinct wire types and certifications of the solar cables that match your installation requirement. Furthermore, seeking professional assistance from qualified electricians will help ensure that your solar panel wiring is done correctly and safely.

Issue #3: Inadequate Sunlight Exposure

The efficiency of your solar array is directly impacted by how much sunlight exposure the panels receive. If your system is installed in a location where there's an insufficient amount of direct sunlight, the solar panels will not be able to generate the desired amount of energy. Hence, selecting the best location for your solar panels is absolutely crucial for maximising power generation.

Before the installation process, conduct thorough research to identify the most suitable location for your solar array. Review the usage patterns of your home or office space, and assess the impact of nearby structures or vegetation on the sunlight received at different times of the day. By analysing these factors, you'll be better poised to choose a location that ensures your solar panels receive the maximum possible sunlight throughout the day.

Issue #4: Suboptimal Angle Orientation

Just as vital as sunlight exposure, the angle of your solar panels plays a significant role in determining their efficiency. In the UK, for example, solar panels should ideally face south and be installed at an angle between 30 and 35 degrees for maximum energy yield. Neglecting to fine-tune the angle of your solar panels can diminish their energy production, and lead to a waste of potential solar generation.

To address this issue, you might consider using an adjustable mounting system that allows you to fine-tune the angle of your solar panels according to the changing seasons. With this flexibility, you can ensure that your panels always direct towards the sun, optimising energy capture all year round.


Solar panel installations don't have to be an intimidating process if you are equipped with accurate information and professional guidance. By understanding these typical issues and their solutions, you can prepare yourself to face – and resolve – any challenge that may arise during your installation.

Embrace preparation, and don't risk overlooking any details. Take the time to select the right mounting system, ensure correct wiring, find the perfect location for sunlight exposure, and adjust the angle of your solar panels. By doing so, you'll have a much better chance of enjoying a smooth, hassle-free installation process, while maximising the efficiency and power output of your solar energy system.

Transcending these common obstacles can significantly enhance your solar power experience, resulting in long-term savings and providing you with clean, renewable energy for years to come.
