Frequently Asked Questions About Solar Panels: Everything You Need to Know

Yes, solar panels can overheat in certain conditions. Although they are built to handle high temperatures, too much heat can reduce their performance and efficiency.

In the UK, the weather is generally mild, making it ideal for solar panels. However, overheating can still happen and cause lower power output, shorter lifespan, and potential damage to the panels. To prevent this, it’s important to have proper installation, regular maintenance, and good airflow around the panels.

No, solar panels cannot generate electricity at night because they need sunlight to produce power. During the day, solar panels convert sunlight into electricity, even in winter or on cloudy days. But at night, with no sunlight, they can’t work.

However, you can still use solar energy at night with battery storage solutions. Solar batteries store the energy your panels generate during the day, allowing you to use it when it’s dark. Additionally, if you have a grid-connected system, you can use electricity from the National Grid to meet your energy needs at night.

Yes, solar panels are getting more efficient. Technology is improving, and ongoing research is working to make them even better. Right now, most home solar panels are about 15-23% efficient, with some high-end ones reaching around 23%.

Elon Musk suggests that we might eventually see efficiency levels of up to 30%, but there’s a limit to how much more efficient they can get. With constant advancements, we could see even more improvements in the next decade.

Solar panels are not completely self-cleaning, but they do have some self-cleaning features. They are made from self-cleaning glass, which helps resist dust, dirt, and debris. Rain can wash away some of the dirt thanks to their special coating and the angle of installation.

However, in very dry and dusty areas, rain might not be enough to keep them clean. Regular maintenance is recommended to make sure your solar panels work at their best.

In a standard solar panel system connected to the National Grid, the panels won’t work during a power cut. This is a safety feature to protect the grid engineers.

However, if you have an off-grid or hybrid solar system with energy storage (like batteries), your solar panels can still provide electricity during a power cut.

If you want backup power during outages, talk to your solar installer about adding an Emergency Power Supply (EPS). This will let your system provide power when there’s a blackout, which is useful for homes in areas with frequent power cuts.

Yes, you can install solar panels without a smart meter. Smart meters measure your electricity use and how much power goes to and from the grid.

While you don’t need a smart meter to install solar panels, having one helps you take advantage of special energy rates like off-peak and economy 7 tariffs. These rates can help you save on charging batteries or electric vehicles and get rewards for the energy you send back to the grid.

If you want an export tariff or off-peak rates, your meter needs to record data at half-hourly intervals. It doesn’t have to be “smart,” but it should be able to track import and export data.

Yes, solar panels can help power a hot tub! Solar panels can provide electricity for many things, including hot tubs. However, hot tubs use a lot of power, so you’ll need to use your solar panels along with high-voltage batteries and take advantage of off-peak electricity times to make it work efficiently.

If you’re thinking about getting solar panels, now is a great time to start. Installing solar panels can help you generate your own clean energy.
