Solar Panels Demystified: Answers to Common Questions and Myths


In an era where renewable energy sources are gaining momentum, solar panels have emerged as a prominent solution to harness the power of the sun. However, with their growing popularity, questions and misconceptions are not uncommon. In this post, we’ll demystify solar panels by answering some common questions and debunking the myths. By the end, you’ll have a clearer understanding of this sustainable energy technology.

How Do Solar Panels Work?

Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electricity through a fascinating process. When sunlight strikes the solar panels, the photovoltaic cells within them absorb the photons. This absorption generates an electric field across the layers of the cell, resulting in the flow of electricity. Then, an inverter converts the direct current (DC) into alternating current (AC), making it compatible with household electrical systems.

Are Solar Panels Effective in Cloudy or Cold Climates?

Contrary to popular belief, solar panels can still generate electricity in cloudy or cold climates. While direct sunlight is the ideal condition, solar panels can still utilise diffused sunlight to produce power, making them functional even on overcast days. As for cold climates, solar panels actually work more efficiently in cooler temperatures, since excessive heat can decrease their performance.

How Long Do Solar Panels Last?

Solar panels are built to withstand the elements and have a long lifespan. Most manufacturers offer warranties ranging from twenty to twenty-five years, but solar panels can continue to produce electricity for well over thirty years with the right maintenance. It’s crucial to choose reputable brands and ensure regular cleaning and inspections to maximise their longevity.

Do Solar Panels Require a Lot of Maintenance?

Solar panels are relatively low maintenance, requiring minimal attention. Regular cleaning to remove dust, debris, or bird droppings helps optimise their efficiency. Plus, it’s advisable to have a professional inspection every few years to ensure proper functioning and address any potential issues.

Can I Use Solar Panels During a Power Outage?

In most cases, standard grid-tied solar panel systems are designed to shut down during a power outage for safety reasons. This is to prevent sending electricity back into the grid while utility workers are making repairs. However, there are options available, such as battery storage systems, which allow you to store excess energy produced by solar panels and use it during power outages.

Can I Install Solar Panels on a Rented Property?

Yes – you can install solar panels even if you live in a rented property, but it requires careful consideration and agreement from your landlord. Discuss the idea with your landlord and highlight the benefits, such as potential energy savings and increased property value. Some landlords may be open to the idea, especially if they can benefit from the financial incentives or if it enhances the appeal of the property for future tenants.

Can I Sell Excess Solar Energy Back to the Grid?

It’s possible to sell excess solar energy back to the grid through a process called net metering or feed-in tariffs, depending on your location. Net metering allows you to offset the cost of your electricity bill by sending surplus energy generated by your solar panels back to the grid. This excess energy is then credited to your account, ready to pay for any electricity consumption when your panels do not produce enough electricity. On the other hand, a feed-in tariff involves a fixed rate at which you are paid for the excess energy you feed back into the grid.

Will Solar Panels Increase the Resale Value of My Home?

Installing solar panels can increase the resale value of your home. Various studies and market trends indicate that homes equipped with solar panel systems have a higher market value and tend to sell faster compared to homes without solar installations. Buyers are increasingly seeking energy-efficient homes that offer long-term cost savings and environmental benefits. Solar panels provide these advantages by reducing or eliminating electricity bills and offering a clean, renewable energy source.

What Happens to Solar Panels at the End of Their Lifespan?

At the end of their lifespan, solar panels can be recycled to minimise waste and maximise resource utilisation. Solar panel recycling involves the process of dismantling and separating the various components for further reuse and material recovery. Recycling facilities use specialist techniques to ensure proper disposal of any hazardous materials, so always have your solar panels professionally recycled.

Debunking Myths

Here are some common myths about solar panels, debunked:

Solar Panels are Very Expensive

One of the most common misconceptions about solar panels is their high cost. While the initial investment may seem significant, the long-term financial benefits are often overlooked. With government incentives, tax credits, and reduced electricity bills, solar panels can provide substantial savings over their lifespan. Plus, advancements in technology and increased demand have significantly lowered the cost of solar panel installations in recent years.

Solar Panels Cannot Power Electric Cars

Charging electric cars via solar panels is an exciting possibility for sustainable transportation. By installing additional solar panels or utilising excess energy from existing panels, it’s entirely feasible to power electric vehicles using solar energy. In fact, companies like specialise in set-ups for this specific situation. Not only does it reduce carbon emissions, but it also contributes to long-term cost savings by eliminating fuel expenses.

Solar Panels are Not Suitable for Residential Use

Another common myth is that solar panels are only practical for large-scale projects or commercial use. However, the reality is that solar panels are an excellent choice for residential properties. Homeowners can benefit from reduced energy bills, increased property value, and the satisfaction of using clean, renewable energy. Various installation options, like rooftop or ground-mounted systems, make solar panels adaptable to different residential settings.

Solar panels are a remarkable technology offering numerous benefits, from generating clean and renewable energy to reducing electricity bills and contributing to a greener future. By embracing solar panels, we can reduce our reliance on fossil fuels, decrease carbon emissions
