Installing solar panels may be a fairly daunting process, however, after reading these FAQs hopefully, you should feel comfortable with this installation and maintenance of solar panels!
How costly are solar panel repairs?
Newly constructed residential solar power systems are normally expected to last 25 to 30 years before needing any significant maintenance. The warranty is undoubtedly the most important element in the minimal maintenance needs of solar power systems.
When considering the mechanical engineering of solar panels, it becomes more clear why they require relatively little upkeep. There aren't many components, which means fewer things may go wrong with them. Few possibilities exist for things to go wrong. Only periodic hose washing is necessary to prevent dirt from obstructing the panels. Remember not to use water that is too cold or to shower your solar panels during the hottest parts of the day when cleaning them.
If you'd want to avoid using a water hose because washing off your solar energy is too difficult for you since it's too high up, etc., professional solar panel cleaning services are available. Even installing sprinkler systems made of solar panels on their rooftops is something some homeowners do.
Another approach to assess solar panels' low maintenance costs is to look at the substantial warranties that, on average, various providers offer. A manufacturer's warranty is currently included with the majority of solar power systems available on the market, and it typically offers a 25-year or longer performance guarantee of 85%.
Will my solar panels still function if the electricity goes out?
If there is a power cut your inverter will switch off, which stops any generation from your Solar Panels entering the property. This security measure is intended to safeguard employees who could be fixing the grid. However, if there is a power outage, we may create a backup system that would let you use your solar power.
Do solar panels need constant repairs?
The simple answer is no, unlike complex electrical systems solar panels are made to last and stay on your roof throughout all weather all year round!
Which types of weather do solar panels work in?
Cold Weather
Instead of the sun's heat, solar panels rely on its light. In actuality, solar cells, like the bulk of electrical equipment, perform best in cooler settings. Contrary to popular perception, too much heat might make the cells less effective. On a cool, bright day, solar cells will produce more energy than they will on a hot, sunny day.
This happens as a result of the energy difference between the photons from sunlight and the electrons in the solar cell. The energy differential between the two groups of particles causes an increase in the quantity of electricity produced. In colder conditions, the difference between them is greater, indicating that more power is generated inside the cell when it is lit by light.
Cloudy Weather
Unfortunately, the benefits of colder weather are negated by the fact that there is less sunshine throughout the winter. The fact that the UK only receives 30% of the maximum amount of sunshine each year, with the winter months having the least amount, won't come as a surprise to many people. Depending on the cloud density, this might restrict solar energy generation to a different extent. The solar panels will receive less sunlight as the cloud cover thickens.
Solar cells can nevertheless produce an astounding amount of power on days that aren't exactly clear and bright.
Snowy Weather
Since snow cleans your solar panels as it melts and increases the amount of light reaching your panels by reflecting sunlight, snowfall may be advantageous for your solar system. This results in more electricity being generated.
Are solar panels expensive?
In terms of solar panels, the initial expense may seem large but when put into consideration the many savings you shall make as a result of implementing these panels, the cost appears far less. There are many ways that solar power proves to be cost-effective. Solar panels in the UK still receive enough sunlight to lower your electricity costs by more than 50%, even in Scotland's most isolated areas. This shows how your electric costs shall dramatically decrease.
A key statistic which implies how solar panels are so worth the initial cost is that within an average of 12.9 years, solar panels will pay for themselves! If you sell your house prior to the 12.9-year mark your house property price will still increase between 0.9 and 2% making your home more valuable! As we are living in a cost-of-living crisis, we understand that solar solutions are just as important to you as they are to us!
How do solar panels work?
Photovoltaic cells, the building blocks of solar panels, transform solar energy into electrical current. Between layers of semiconducting materials, such as silicon, are sandwiched photovoltaic cells. When photons from sunshine strike each layer, its unique electronic characteristics energise and produce an electric field. The photoelectric effect is what causes the current required to generate energy.
Electricity produced by solar panels is in the direct current form. This is then sent via an inverter to change it into an alternating current that may be used by the building or structure that the solar panels are mounted on, the National Grid, or both. You can learn more about this from the Institute of Physics.
How much power do solar panels create?
Typically, a 350 W solar panel will produce 0.72 kWh of power daily. However, this is just one panel. The typical three-bedroom home requires a system with at least 10 panels to meet its power demands (although half of this electricity won't actually be consumed - but more on that later), which translates to the solar panel system producing 7.2 kWh of electricity daily.
Solar panel production in the UK decreases over the winter, as you would have anticipated, typically by roughly 50%. Due to shorter days throughout the winter, panels are not exposed to as much sunlight as they are during the summer. In the winter, the sun is also lower in the sky, which may affect how much sunlight is received. This indicates how domestic solar solutions can hold enough power to truly combat grid energy!
What does the PV stand for in solar PV?
PV is an acronym for photovoltaic (light) and electric. Light is converted into power by solar PV panels. Not sunshine, but light, please. Even on overcast days, they continue to generate power. Just that the brightness of the light will increase their production. The utilisation of light to generate electricity dates back to the 19th century!
For my home, how many solar panels will I need?
Calculate the amount of solar panels you require by calculating your annual power usage and multiplying it by the 265 kWh that each 350-watt solar panel generates in the UK. Check your roof next to determine whether it can accommodate this many solar panels and to make sure it isn't facing north, which will make installing panels considerably less profitable. To gain a more accurate quote on how many solar panels will be needed to power your home and how much this will cost please contact our team of solar PV panel installers.
How much roof space is needed?
The average roof area has the capacity to produce 15 watts of solar energy per square foot. Therefore, a small home may only need about 200 square feet of roof space for a solar panel installation, but a bigger home may need more than 1,000 square feet of roof area to effectively offset power demand.
You don't need a sophisticated solar panel square footage calculator to estimate how many panels a roof can hold. For the needed solar setback, multiply the roof's square footage by 0.75. Divide that amount by 17.5, which is the typical square footage of a solar panel of that size. The total amount of solar panels that can fit on your home's roof is the outcome! This is just a general guide!
