Solar energy is one of the most significant and effective types of renewable energy sources in the world. We harvest the natural solar energy in order to produce electricity that is used to light and heat buildings and homes. Your system could produce electricity or heat your water whilst reducing the amount of carbon dioxide produced by your system.
Solar panel installation provides a greener alternative to other forms of energy such as central heating since they do not emit greenhouse gas emissions or pollute the air whilst operating. There have been many improvements through the years to the development of PV modules and more recently battery storage. They are now much more accessible and affordable. Solar energy can save homeowners and businesses hundreds of pounds a year on electric expenses.
Solar power is generated by each PV cell. These cells are joined together to form solar panel system that is composed of cells and material that conducts electricity. They are able to convert solar energy to generate electricity for the use of your home.
There are several things we can look at to help you determine if installing solar panels could be the right choice for you.
Different types of solar Panels
Firstly, the types of solar PV panels and the one you select will depend on the purpose you require it for, and also the space you have available and the amount of money you’re able to invest in the panels. Solar cells have made significant progress since their first appearance. They’re now more sophisticated, which makes them not just more efficient but more aesthetically pleasing too. The primary varieties of solar panels on the market are:
Monocrystalline solar module: these type of solar panels occupy less space than polycrystalline panels but are about the same efficiency. They can be more expensive, however.
Polycrystalline solar panel: the manufacturing process is much simpler. This means they are less expensive, however they are slightly less efficient at higher temperatures but not enough to worry about when used for residential uses. They do, however, require more space as you will require more of them.
Thin film solar cells: these are made by using substrates and photovoltaic cells and using various layers of the substance onto a substrate base. There are numerous materials that can be used, they are simple to make in large quantities as well as being less costly as well as more adaptable.
Amorphous silicon solar cell: These typically come with several layers that are stacked together to increase their efficiency, but, in comparison to other kinds, these are less efficient.
Biohybrid solar cells: These are made to make use of an approach that is more natural to photosynthesis by combining organic with non-organic substances. This means almost 100% efficiency, but they are less efficient in general.
There is also the option of buying roof tiles that are solar. They look like regular roofing tiles but incorporate a battery. If you have an listed home, these may usually be the best choice, and they are most sought-after by those who think solar panels don’t appear appealing. They are a lot higher priced than photovoltaic PV since you’re likely to spend approximately PS10,000 for a home of 3 people.
There’s also a difference in solar panel and solar cell. Solar cells have all the essential components required for converting sunlight into electricity. The cells are connected to form a solar panel which generates more electricity.
Storage of energy is becoming more efficient. As solar batteries become more widely used, the energy that produced by your system during day is stored to be used during the night, or on cloudy days when less power is produced. This is a good way to make sure your home is significantly more energy efficient and get the most out of your panels.
It is often believed that the sun has to shine directly on the solar panel in order for it to function effectively, but this is not the case. They can still produce electricity even on cloudy days, but they’ll work far more efficiently on sunny days in the summer than winter as the sun is higher in the sky. The best panels can achieve the efficiency of around 22 percent. This is a very high level of efficiency as most are around 15%.
Solar Panels’ Benefits
There are numerous benefits of solar energy generation here are few:
It’s eco-friendly: no emissions of pollutants when solar panels operate, so that by using them, you’re using renewable energy to run your home or your business which reduces your carbon footprint.
Cash-saving: Any electricity you produce is totally free of charge and you can use it to power your house or office for free. This will obviously lower your energy bills and also save you money in the long run. You will also be able profit from The Smart Export Guarantee that is replacing FIT which means a faster return on your investment.
No planning permission: installing solar panels doesn’t require special permission. There are some regulations that need to be followed however, it’s generally a simple process.
It’s renewable. The sun will not run out any time soon and it even works on cloudy days, so you should have plenty of free electricity all through the year. You can also install a battery-storage device to keep any power produced that you don’t need during the day. You can utilize it in the evening when the sun doesn’t shine. It will cut your carbon footprint as a bonus too.
They are efficient throughout the year. They are able to produce energy throughout the yearround, not just during the times when the sun shines the most.
Are there disadvantages?
There are several, with the principal one being the cost. There was initially a substantial cost to installing them, however, this has decreased significantly over time and is expected to do so. They are becoming less expensive and simpler to manufacture, which means the cost of buying them has significantly lowered. Also the savings you will make on energy costs will eventually outweigh the initial expense.
Another thing to take into consideration is dependence on sunlight. They work best in sunny conditions, however, they can be effective on cloudy days. They can’t work at evening, so power from the grid will need to be used at specific times. The most effective way to maximize their effectiveness is by using batteries that store energy and ready to use during evening.
The long-term advantages of installing solar is more than the initial investment since it can help you save money.
Since solar panels do not have moving parts, only minimal maintenance and service is required. Like a boiler solar panels are likely to function well without a yearly service. There is enough rainfall in the UK to ensure that you don’t necessarily need to clean them. If you believe that your solar panels aren’t producing enough energy, then there are some checks you can make or call a certified installer to maintain your solar panel system. Solar panel warranties differ, according to the manufacturer and the model you choose. Generally, you’ll find that the panels themselves will be covered for 10 to 25 years. Solar panels tend to last between 25-30 years, that’s at a minimum of 25 years of lower expenses for energy! Additionally is that the panels will not stop working after several decades. However, inverters might need to be changed after 10-20 years.

Be sure to determine what is appropriate for your house prior to you make an investment. Consider what location you are in and how your roof faces. In the UK south is best since your roof panels will be receiving sunlight all day. Also look at your roof. What size is it? How many panels do you need? Are they able to fit? Be sure they’re not shadowed too much by things such as large trees. It is crucial to obtain top quality estimates that take all these things into account.
In approximation Yearly System output
The Feed-In Tariff scheme that was announced in April of this year closed for new customers at the end of March 2019. Existing customers remain to be paid. In the Feed-In Tariff scheme there were two installments, an “generation tariff” and another “export tariff”.
“Generation Tariff” The “generation tariff” is the price you pay for all the electric energy generated by a household. Rates were set by government, and depended upon the size of the solar PV system you had and when you signed up to the scheme. In the beginning, rates were much higher – some paid more than 50p per kilowatt hour but decreased over time and dropped to 4p for new customers by March 2019. Once you’d obtained a rate, it would be locked for the length of your contract. Typically, it was 20 or 25 years. The payments reduced the overall time it took to get back your initial investment. The government abolished the FIT this year due to solar panel prices soaring and also being more affordable.
“Export Tariff “export tariff” was a payment to homeowners for surplus energy that they sold to the grid. Rates were set by the authorities for the duration of the contract duration, and were similar to the market rate for electricity. It was 3.82p/kWh from August 2012 until then 5.38p until the Feed In Tariff scheme came to an end. In the Feed-In Tariff all households were provided with the same rate, that was 50% of all the energy generated by the solar panels. The actual amount of electricity exported to the grid was not accounted for, so everyone got this regardless of the amount of energy they exported.This has changed slightly in 2019 , and is known as the generation rate tariff. Your supplier has agreed to a fixed price to compensate you for the energy per kWh that you generate. It is crucial to note that the rate can alter each year in new projects, and will be adjusted according to the rate of inflation. The payment will be similar to that of FIT which will then be paid to you for a period of 20 years, and possibly longer until the system generates enough energy.
Though the Feed-In tariff has ended and some of the power generated by solar panels will ultimately return to the grid. Since under current legislation , it will be illegal not to be paid for this a new system has been created. This is the point where you can benefit from the Smart Export Guarantee comes in to help.
‘Rent a roof’ programs are no longer in existence due to the government’s removal of the FIT.
Also, there is Renewable heat incentives (RHI). This is available to pay for solar thermal systems that can warm the hot water in your home. Payments are made for up to 7 years and is based on the amount heat your system makes. If you own your own home in England, Scotland or Wales You can apply through the government website.
Smart Export Guarantee
The Smart Export Guarantee is great news if you are hoping to earn your money back on your initial investment. Following the announcement by the government of the changes to the FIT the new solar projects were thrown into uncertainty, but now the government has an idea to ensure the future of the solar industry.
What exactly is what is the Smart Export Guarantee? Final proposals to implement the Smart Export Guarantee was released from the government the 10th of June, 2019. The Smart Export Guarantee demands medium-sized to large electric supply companies including SSE, EDF Energy, British Gas, npower, EON UK and ScottishPower (those that have more than 150,000 electricity customers) to offer a smart export guarantee (SEG). Smaller suppliers can do so on a voluntary basis. Some suppliers are already beginning to offer SEGs. However, all of them must to provide the terms of payment you need for your electricity from solar panels, wind turbines and others renewable energy imports by January 1st, 2020 by the latest.
This is great news for solar panel owners, because the scheme will be regulated rather than being subventioned. In the past , the Feed in Tariff offered a fixed rate set by the government. Now, instead of being a subsidy it will be an introductory rate. After the new system has kicked in, it seems likely that there will be a competition among energy providers to offer better prices in order to earn your trust.
To benefit from the proposed Export Guarantee scheme you need to install an MCS-certified installation. In addition, anyone who installed solar panels in the period between the expiration of Feed in Tariff and the start in the scheme’s new phase will qualify for the new scheme.
The Solar Trade Association has been insisting that households be paid at an appropriate market price for the power they provide to the electric grid just like others generators do. There are two obvious ways to define fair pricing. One is by wholesale prices, which is the rate at which the market pays for power in order to sell it to you for 2018, it was approximately 6p/kWh. The other is the ‘System Sell Price’, which was cited by the government as a fair price in the SEG consultation. It is the amount that larger generators get in exchange for surplus power when they generate more electricity than what they previously agreed to generate. The annual average System Sell Price last year was very similar (5.4p/kWh) with the prior FIT export tariff which was 5.2p/kWh.
This is a great option for anyone who is considering going for solar panels but putting off due to the loss of this Feed in Tariff. While prices have decreased significantly over the past decade however, the new plan is also likely to become more generous than the current tariff. With solar costs dropping by over 80% since 2008, it was the right time to review the way these payments were paid. Business and homeowners who install the latest solar panel will receive assured of payment for the power they generate back to grids to enable the smart energy systems in the near future. This can only be an important upgrade to the current Feed-in-Tariffs scheme.
Smart Export Guarantee Smart Export Guarantee will see electricity providers paying smaller-scale producers of energy for excess energy from both businesses and homes being put back into the grid of energy. The new program could lead to the creation of a whole new market, which will encourage suppliers to bid competitively on this electricity, providing exporters the most competitive price, while also providing the local grid with more green, clean power, giving more options and control for solar householders over the purchasing and selling of their electricity.
In the present, the government is obligated to electricity supply companies to buy electricity at prices that are above zero. The good news is the power sector is changing rapidly and there are a lot of suppliers that are keen to move to smart energy to deliver more efficient, low-carbon power system, and they are looking for customers who want to participate. Companies that have been the first to embrace in the system’s new features include Octopus who offer adjustable and fixed-rate SEGs Bulb which is offering customers who produce their own electricity payment for the electricity they generate and export to grid (This is for solar-only customers either storage-only or solar with storage co-located) and EON which is paying the first 500 new solar customers 5.24p for every kilowatt-hour (kWh) of energy exported back to the grid , based on the assumption that 50% of generation is exported.
The more complicated new system could take some time to establish, but there are still savings to be made , which will grow as the major energy firms come to the system and begin competing with one another.
It is often asked if it is possible to fit or even construct yourself a solar-powered system. It is feasible to do so and it is a much cheaper option. There are a few points to take into consideration:
To be eligible for the new proposed export Guarantee policy, your need to have an MCS certified installation.This should be performed by a certified engineer to ensure that the safety standards are adhered to. It can be difficult to convince someone to carry out this for a system that they didn’t put in themselves. Also, there might be issues when you plan to sell your property.
