10 solar myths and facts you need to know

We tell the truth behind the most widespread solar myths and facts that you need to know if you are thinking of going solar.

Myth 1. Solar cannot function in cloudy weather

One of the most widespread myths is that if there is no sun, the residential solar system does not produce any solar electricity. It’s true that snowy and cloudy weather reduces the amount of energy produced by residential solar, but it still generates electricity. According to general estimates, solar systems will generate about 15 – 25% of their normal power output on a cloudy day.

Myth 2. Solar does not work in extreme hot or cold temperatures

There is a misconception that residential solar systems do not work when it is extremely cold or hot. Roofit.solar modules can operate in -40 to +85 °C conditions. However, high temperatures reduce the efficiency of solar cells when converting solar energy into electricity. This means that solar systems are more efficient at cooler temperatures. E.g. If a solar panel is 60° hot, the efficiency drops by around 16% compared to a 25° hot panel.

Myth 3. Going solar costs a fortune

Solar photovoltaic module prices have fallen by 89% since 2010 making them more and more affordable, thus, the myth that only well-off people can afford solar is not true. Also, it is not reasonable to wait for more reduction in solar product prices as the amount you are saving by not buying a solar roof is going out of your pocket for paying constantly increasing electricity prices.

Myth 4. Solar energy systems do not last long

On the contrary, rooftop solar systems are highly durable, weatherproof, and can last very long. Many solar panel manufacturers provide an average of 10-year product warranty and a 25-year performance warranty, meaning there is a guarantee the panels will produce electricity no less than 80% of their power output rating at the end of 25 years. It means that your solar roof will be serving you for the decades to come.

Myth 5. Solar panels use more energy during manufacturing than they produce

Of course, all forms of energy production have some impact on the natural environment. However, it has been proven that the environmental impact of manufacturing solar panels is minimal compared to the extraction of fossil fuels, gas, or other energy sources. That’s why solar energy is one of the best ways to tackle climate change.

Myth 6. Rooftop solar systems make your home unattractive

In general, regular solar panels are bulky and unattractive, and it is very easy to spot them on the roof from far away. However, for those who do not want to compromise the looks of their homes, there are more aesthetic solutions. Roofit.solar metal solar roofs are one of those cutting-edge innovations. They look like traditional steel roofs but generate as much electricity as regular solar panels.

Myth 7. Solar systems require constant maintenance

Solar systems require minimal maintenance to function, which includes yearly inspection to spot some potential problems. The removal of some debris, leaves, or dirt obstructing the sun’s rays may also be required from time to time. Usually, regular solar panels need more maintenance during heavy snowfall compared to Roofit.solar products, as the snow usually melts itself when the metal solar roof gets warm.

Myth 8. Solar panels are made of toxic materials

96% of all solar panels installed globally are made up of silicon crystalline PV cells encased in polymer material and protected by glass. There are no toxic materials except for a trace amount of lead used in the solder. After the panels have reached their lifetime, they are sent to specialized PV recycling facilities where they are taken apart and recycled.

Myth 9. Small solar installations cannot have any environmental impact

People think that small solar installations cannot have any significant positive impact on the environment, and believe that only big solar systems can make a real change. This is wrong. On average, one 10 kW solar roof eliminates around 4 tons of carbon emissions annually, which is roughly equivalent to planting over 100 trees per year. Larger installations can have 10 times the effect. Therefore, each solar roof owner plays a huge role in mitigating accelerated climate change.

Myth 10. Solar energy is not reliable

As the sun goes down at night, people believe that solar energy systems are not reliable or worth the investment. Technically, solar panels do not produce energy at night but that’s not the bottom line. Solar systems enable two indirect nighttime energy solutions: Electric grid connection with net metering and solar battery storage. Both allow your solar energy system to provide electricity when your solar panels are resting. And after all, the sun always comes back in the morning. This means that solar systems are as reliable as solar energy, which is free, infinite, and green.
