Solar Panels: Frequently Asked Questions
How do solar panels work?
Solar panels work by converting sunlight into electricity. The panels are made up of photovoltaic cells, mostly made of silicon and absorb the energy from the sun's rays and convert it into a direct current (DC) electricity. An inverter then converts the DC electricity into alternating current (AC) electricity that can be used to power your home or business. The cells do not need direct sunlight to work and can even work on cloudy days. The stronger the sunshine, the more electricity is generated.
Will solar panels work on cloudy days?
While solar panels work best in direct sunlight, they can still generate electricity on cloudy days. They are designed to absorb all types of light, not just direct sunlight, so they can still produce electricity even when the sky is overcast.
How long do solar panels last?
Solar panels are built to last for decades. Most panels come with a warranty of 25 years or more, and many panels have been known to last for up to 40 years with proper maintenance.
How much will I save on my energy bills with solar panels?
The amount you can save on your energy bills with solar panels will depend on several factors, including your location, the size of your solar panel system, and your energy usage. Using a battery to store the energy produced by your system will save you more over time. With the price of electricity
How much does a solar panel system cost?
The cost of a solar panel system will depend on the size of the system, the type of panels used, and the complexity of the installation. On average, a residential solar panel system can cost anywhere from £7,000 to £20,000.
Will my solar panel system work during a power outage?
If you have a grid-tied solar panel system, it will not work during a power outage. This is because the system is designed to shut off automatically when the power goes out to protect utility workers who may be working on the power lines. However, you can add a battery backup system to your solar panel system to provide backup power during outages.
Will putting solar panels on my roof make selling my house more difficult?
Some years ago, solar panel systems were funded by leasing space on your roof to a company who would pay for the solar panel installation. These companies would put a charge on the property which added an additional hurdle when trying to sell a property. Solar panel that we supply do not involve leasing roof space to your installation company. In fact, solar panel systems can add value to your property. Josh Jackman from The Eco Experts says that: 'Solar panels will typically make selling your home easier, not harder. The latest research shows that homes with solar panels typically sell for 4.1% more than those without – which currently means you pocket an extra £11,000.'
Do I need permission to install a solar PV system?
Solar PV panels are considered ‘permitted developments’ and often don’t require planning permission. However, if you live in a listed building, conservation area, national park or area of special scientific interest, additional restrictions may apply.
Do I need to inform anyone when getting a solar panel system?
If you’re planning to install a solar PV system in your home, you must register it with your Distribution Network Operator (DNO). The DNO is the company responsible for bringing electricity to your home. One of our professionals at Solar Boost will register your solar panel system with the local DNO once we have been instructed to fit your solar panel system.
What if there are trees or other obstructions shading my roof?
This is an important question and there is a solution to partial shading of a solar panel system. If the shading is permanent such as another building the answer could be to calculate the impact of permanent shading on the system as a whole and reorientate the panels to minimise this shading impact. If the shading is temporary such as the movement of trees the output of the whole array of panels can be reduced, to solve this DC Power Optimisers can be fitted to each panel so that each panel can work separately to whole array of panels and only those panels impacted by shading suffer from reduced output.
My roof doesn’t appear to be ideal for solar panels what should I do?
Even if your roof doesn’t fit the ideal requirements, it can still be suitable for solar panels. By speaking with to one of our professionals, they will be able to advise on different designs and technologies to maximise your system’s performance.
