Solar panels have become increasingly popular as a renewable energy source, with more and more homes opting to generate their own solar electricity. If you’re considering installing solar panels, you likely have some questions that need answering before making the investment. In this article, we will provide answers to some of the most frequently asked questions about solar panels.
How do Solar Panels Work?
Solar panels are composed of photovoltaic cells, which contain silicon. When sunlight strikes these cells, the electrons within the silicon start to move, generating direct current (DC) electricity. This DC electricity is then converted into alternating current (AC) electricity, which can be used to power our homes and businesses.
Do Solar Panels Require Cleaning?
Most solar panels are designed to be self-cleaning, as rainfall helps wash away dirt and debris. However, in certain cases, excessive buildup of dirt can reduce their productivity. If you notice a significant decrease in the performance of your solar panels, it may be necessary to clean them. However, it is important to exercise caution when attempting to clean solar panels, as climbing onto your roof can be dangerous. If you are not confident or experienced in roof work, it is best to hire a professional to clean your panels.
Is a South-facing Roof Necessary for Solar Panels?
While solar panels can be installed on roofs facing any direction, they perform better and generate more electricity when they are south-facing. South-facing panels receive the maximum amount of sunlight throughout the day, optimizing their energy production. However, even on non-south-facing roofs, solar panels can still perform at around 86% compared to south-facing ones.
How Many Solar Panels Does My Home Need?
The number of solar panels your home requires depends on your energy usage and the number of people living in your home. The more solar panels you have installed, the more electricity your home will be able to generate. We offer bespoke solar systems tailored to suit your property and energy needs. Our team will help you determine the most suitable system for your house.
What is the Lifespan of Solar Panels?
Solar panels generally have a lifespan of around 25-30 years. However, it is important to note that this does not mean they stop working entirely after this period. Instead, their output gradually decreases below the initial projected levels. Solar panels are durable and have no moving parts, which means they require minimal maintenance once installed.
Do Solar Panels Require Constant Sunshine to Work?
Solar panels do not require constant direct sunlight to work effectively. They can still generate electricity even when the weather is cloudy. While direct sunlight does maximize their energy production, solar panels can harness diffuse sunlight and convert it into usable electricity. This means that solar panels can still be a viable option for homes in regions with less sunny climates.
Can Solar Power be Stored?
Yes, solar power can be stored using battery storage systems. These systems allow you to store excess electricity generated by your solar panels for later use. We offer battery storage systems as part of our solar panel installations. With a battery storage system, you have the option to use the stored electricity during times when your panels are not producing enough energy, or you can even sell it back to the grid.
