How Long Do Solar Panels Last?

As an alternative form of energy, solar panels are becoming increasingly popular all thanks to a wide range of benefits it provides. It does not produce any emission which makes it greener and more environmentally friendly, it requires little maintenance and are less likely to break down, they also come with warranty that are always quite long mainly because of the life expectancy of the average solar panel amongst many other advantages. Therefore, if you’re considering to purchase and install new solar panels within your home, you’d also probably want to know the time period in which they’re expected to last. In this article, we aim to help you answer this question so you can make an informed decision going ahead.

As a result of the rising energy bills as well as the desire to be greener, solar panels are becoming increasingly popular by the day in the UK. The most recent models of solar panels in the market possesses an expected lifespan of 40 to 50 years as well as warranties that keeps them protected for a minimum of half of that period. These warranties also serves as a guarantee to the solar panel’s level of performance over the first half of their lifespan. Several warranties will guarantee that the performance will not go below 80 percent before the warranty lapses. And even more importantly, some solar panels are crafted in such a way that they wouldn’t drop below 80 percent performance level throughout their lives.

However, in order to derive maximum benefits from your solar panels for a long period, there’s a need to ensure they’re properly maintained at least once a year throughout their lifespan.

If you’re looking to install some new solar panels in your home or property, then you’d probably want to know how it works. This is one of the most frequent questions asked by homeowners when it comes to solar panels and in this article we aim to give you a good insight on the operations of solar panels. Let’s have a look!

Generally, solar panels work by absorbing the energy of the sun and then converting it into electricity. It functions by allowing photons from the rays of the sun release the electrons free from atoms within the photovoltaic or solar cells in order to produce a flow of electricity. There are several solar cells that are connected together ( usually 60 or 72 ) in each panel. Individual cells comprises both a negative layer and a positive one which combines perfectly to create an electrical field in which the energy is generated.

The boron that’s within the bottom layer generates the positive charge, while the phosphorous found in the silicon layer produces the negative charge. In order to convert the sun’s rays into the energy that’s going to be transported from the panels to the inverter, the two field will interact with one another.

In other words, solar panels work by turning photons from the sunlight into direct current which is transmitted to the inverter. Once it gets to the inverter, it’s then translated to alternating current and send this current to to your electric box which powers the entire home. If you do not wish to reduce the high bills that’s associated with renting power from the grid, the solar energy system is an efficient and affordable way to achieve this aim.

Solar cells , also referred to as photovoltaic cells (PV), absorbs energy from the sun and converts it to generate electricity. This, however, should not be confused with photovoltaic thermal cells or PVT which operates to generate heat for water in homes. Solar cells are linked electrically and also carefully organized into a large frame which is popularly called solar panels. Generally, solar cells are produced or made of silicon semi conductors which works to absorb sunlight and then turn it into electricity for use at a home. A solar panel comprises of either 60 or 72 solar cells which are electrically interconnected in series and parallel and also positioned in between glass and plastic which is then framed.

At present, solar panels incorporated for residential or domestic purposes only possesses the capacity to make use of only about 20 percent of the sunlight they’re able to absorb and convert it to electricity - also called solar efficiency. Available in the market are also a wide range of solar cell available for both industrial and commercial purposes. This type of solar panels have an efficiency rating of about 40 percent which will also automatically make them more costly than the domestic types.

One great thing about the solar industry is the fact that it keeps improving in such a way that raises both its efficiency as well as overall quality. And with further research and development, this is expected to even increase as the years go by. What’s more? As these aspects keep rising, it’s also expected that the solar panels price should be on a decrease. That way, they’ll become available to a wider range of individuals who’ll also like to save money on electricity bills and go greener.

There are two different types: flat plate, where lots of thin tubes carry water through a flat absorber panel, and evacuated tube, where vacuum glass tubes capture the sun’s energy directly. There is little difference in performance between the two but evacuated tube panels do more obviously extrude from the roof.

You shouldn’t need to maintain your solar panels much at all as long as there’s nothing piled up on top of the panels that could block out the sun. They are installed at an angle, so when it rains the water runs off them and gives them a clean. However, if this doesn’t quite cut it, you can spray them with a hose a few times a year.

If you’re thinking about installing a solar thermal system in your house, it’s always important to put into consideration numerous factors before you proceed. While some solar thermal systems are suitable for use at home, there are also some that are suitable for businesses or organizations which normally requires a big amount of hot water like hotels, restaurants, schools, hospitals and many more. You’ll also find some types available in the market that are suitable for communities to satisfy communal hot water demands.

It should, however, be noted that solar thermal systems do not have the capacity to produce all the hot water demand of a house. In the UK, an average household will need an annual water heating of between 3000kWh to 5000kWh. Whereas, a solar thermal system is only able to meet about 40 percent to 60 percent of this demand.

With that in mind, it’s also worth noting that during the summer months when the solar radiation is at its peak and hot water demand is relatively lower when compared to other seasons, a solar thermal system may be able to provide all of your household’s hot water needs. This implies that during this period you may not find the need to operate your boiler at all. However, during winter or colder months, when you have a higher hot water demands in contrary to a lower solar radiation, a solar thermal system will only be able to take care of about 20 percent of your household’s hot water needs. And that ultimately implies that during this period, you’ll need to rely more on a alternative or backup source of heat like gas, coal, electricity, oil or LPG.

If you’re thinking of adding a solar battery to your home, you might be wondering whether or not it’s going to work in a power cut. If yes, then you’re not alone as this is one of the most common questions asked when it comes to solar batteries. In this post, we aim to provide you with a detailed answer to solve this concern once and for all.

The answer to this question is, it depends. The main reason why your solar batteries will usually not work or provide your home with the much-needed back up power is as a result of the several threats it poses. You should be aware that both your solar panels and battery are connected to the main grid. When a power cut occurs, your engineers will have to operate on the grid. If the solar panels or batteries are in operation at the period there’s a high chance the engineers would be electrocuted by the electricity that’s being produced. As a result of this, solar inverters are usually designed to automatically switch off once a power cut occurs. However, it should also be noted that if your solar battery possesses backup functionality, you’ll be able to make use of your solar energy in the event of a power cut. In other words, what determines if your home battery would work in a power cut is the availability or otherwise of a backup functionality.

Furthermore, you might also wish to know if your solar panels will continue to charge the battery in a power cut. Well, this depends on the type of backup system you possess. There are some more affordable batteries that are designed to automatically release their stored energy upon the detection of a power cut. And this is mostly because the battery inverter is usually smaller than the solar inverter which allows the energy from the solar inverter to the transmitted to the battery - risking an overload. However, if otherwise, then energy can continue to be transmitted to the battery until its fully charged.

Solar panels can be pretty expensive, so require an initial investment. However, a quality solar panel installation can be very financially beneficial, saving you money in the long run. It does this in two main ways.

Firstly, using electricity generated by your solar panels means that you have to use less power from the national grid. Once you’ve bought your solar panels, your solar electricity is essentially free, meaning that you’re saving money by using this instead of power supplied by your energy company. If you want to maximise these savings, invest in a solar battery so you can store unused solar electricity ready for when you need it.

You can also earn money with your commercial solar panels through the Smart Export Guarantee [https://solar-panels.quotatis.co.uk/smart-export-guarantee/]. This is a government scheme that says that all licenced energy suppliers with 150,000 customers or more have to offer a tariff to renewable energy generators. When you generate solar electricity but don’t use it immediately it gets fed back to the grid – the tariff pays you for every kWh of this.

At the moment there’s no minimum tariff that an energy company has to offer – it only has to be above zero. However, many energy companies are competing to offer the best deal, so you can definitely find a tariff that will pay you for all the unused solar electricity you generate.
