Solar energy is one of the largest and most efficient kinds of renewable energy available to the world. We use the natural power of the sun’s rays for electricity to light and heat buildings and homes. Your system could produce electricity or heat your water whilst cutting down on the amount carbon dioxide you produce.
Solar panels are an environmentally friendly alternative to other sources of energy like central heating because they don’t emit greenhouse gases or pollute our environment during their operation. There have been many advancements in the technology behind PV modules, and in recent times batteries. They are now much more accessible and cost-effective. Solar power can save homes and companies hundreds of dollars a year on electricity costs.
Solar power is produced by the individual PV cells. They join together to form the solar panel systems which are comprised of cells and material that conducts electricity. They can then convert energy from the sun and generate electricity to be used around your home.
There are a few aspects that we can take a look at to help you determine if solar panels are suitable for you.
Types of Solar Panels
First of all, the kinds of solar PV panel, and the choice of one, does depend on what you need it for, and the amount of space you have available and the amount of money you’re able to invest in them. Solar cells have advanced since their first appearance. They are now much more advanced, making them not just more efficient, but also more appealing to the eye. The primary kinds of solar panels available are:
Monocrystalline solar module: these kind of solar panels take less space than polycrystalline ones, but they have about the same performance. They may be more expensive however.
Polycrystalline solar modules: the procedure of creating these panels is significantly simpler. This results in them being less expensive however , they’re less efficient at higher temperatures, but not enough to be concerned about for residential uses. However, they do require more space as there is a tendency to require more of them.
Tiny film solar cells are made by using substrates as well as photovoltaic cells. They are then able to apply several layers of the material onto a substrate base. There are various substances that can be utilized as they are easy to make in bulk and can be cheaper as well as more adaptable.
Amorphous silicon solar cells: these usually have several layers that are stacked in order to improve their efficiency. however, when compared with other kinds, these are less efficient.
Biohybrid solar cell: these are designed to use an organic method of photosynthesis. This is done by mixing non-organic and organic matter. This is a close to 100% efficiency, however they do produce less power overall.
There are also roof tiles that are solar. They appear like normal roof tiles but can be fitted with a battery. If you live in a listed property these can usually be the best option and they’re the most popular amongst those who feel solar panels aren’t attractive. The tiles are considerably more costly than photovoltaic PV as you’re probably looking at about PS10,000 for a typical property with three people.
There’s also a distinction between solar panels and solar cells. Solar cells include all of the essential components required that convert sunlight into electricity. The cells are connected to form the solar panel, which creates more electricity.
Energy storage is getting more efficient. Solar batteries are becoming more common, the energy that produced by your system during day can be stored for use in the evening or on daytime clouds when less power is produced. This is a great method to ensure that your home’s even more energy efficient and you get the best out of your panels.
There is a widespread misconception that the sun needs to be shining directly onto the solar panel to work efficiently, as this is not true. They can still produce electricity even on cloudy days, but they’ll work far more efficiently when it is sunny in summer months than in winter because the sun is higher in the sky. The most efficient panels have an efficiency of 22%. This is quite high efficiency , as the average is 15 percent.
The Benefits of Solar Panels
There are many advantages to the production of solar energy, but here are some of them:
It’s eco-friendly: no pollutants produced while solar panels run, and by using them you are using clean energy to provide power to your home or business and reducing the carbon footprint.
Save on cash: any electricity you produce is totally free and can be used to power everything in your business or home at no cost. This will of course reduce your energy costs and help you save money in the long term. Additionally, you will be able to make money from the Smart Export Guarantee that replaces FIT, meaning a quicker return on your investment.
No planning permission: installing solar panels doesn’t require special permission. There are certain rules that need to be adhered to, but the majority of the time it’s easy.
It’s renewable. The sun won’t be running out any time soon and they can even function on cloudy days, so you’ll be able to get plenty of energy available all year long. You can also install a battery-storage device to store any energy produced by you that you do not make use of during the day. Then, use it in the evening when the sun doesn’t shine. This will reduce your carbon footprint as a bonus too.
Efficient all year: they are able to produce energy throughout the yearround, not just during the times when the sun shines the most.
Are there any drawbacks?
There are several, the primary one being the cost. There is initially a high price to get them installed, however, this has decreased a significant amount over time, in the past and continues to decrease. They are less expensive and less difficult to produce so the cost to purchase them has significantly lowered. Also the savings you earn on energy costs will in the end outweigh the initial expense.
Another thing to take into consideration is the dependence on sunlight. They work best in bright sunlight; however, they also work well on daytime clouds. They cannot work during the night and therefore, some electricity generated by the grid is required to be used up at certain time periods. The best way to maximise their effectiveness is to use a battery to store power available for use in the evening.
The long-term benefit of solar panel installation is far greater than the initial investment because it can help you save money.
Because solar panels don’t have moving parts, only minimal maintenance and servicing is required. As opposed to a boiler, your solar panels are likely to function well without requiring a regular service. We get enough rain in the UK to ensure that you don’t usually need for cleaning. If you suspect that your solar panels are not producing enough energy, there are a few checks you could do or you can simply get a professional installer to maintain your solar panel system. The warranties for solar panels vary depending on the manufacturer and the model you choose. The majority of the time, the panels are covered for 10-25 years. Solar panels are typically able to last between 25-30 years, that’s at least 25 years of less costs for energy! Additionally is that the panels will not stop working after several decades. However, inverters are likely to have to be replaced after 10/20 years.

Be sure to determine what is appropriate for your home prior to you make the investment. You must consider where you live and the direction your roof faces. If you live in the UK south is ideal because your panels will be receiving sunlight all day. Take a look at the roof. What size is it? How many panels do you need? Are they able to fit? Make sure that they aren’t overshadowed by things like large trees. It is vital to obtain excellent quality estimates that take all the above factors into consideration.
“Generation Tariff” The “generation tariff” paid for all the electricity that a household generated. The rates were set by government and depended in the amount of your solar PV system as well as the time you joined the scheme. In the beginning, rates were much higher ; many paid more than 50p per kilowatt-hour, but were cut over the years and dropped to 4p for new customers by March 2019. Once you’d secured a rate it was locked for the length of your contract, which is typically 20 or 25 years. These payments reduced the overall amount of time required to pay back your initial investment. The government eliminated this year the FIT this year due to solar panel prices decreasing and also being more affordable.
The “export tariff” compensated homeowners for the surplus energy they exported to the grid. The rates were set by the authorities for the duration of the contract term and were around the price of electricity on the market. It was 3.82p/kWh up to August 2012 and after that 5.38p until the Feed-In Tariff scheme ended. In the Feed-In Tariff all households were paying the same amount that was 50% of all generated energy by solar panels. The actual amount that was exported to the grid was not accounted for as such, therefore all households were paid this regardless of how much energy they exported.This has been changed little in the year 2019, and is referred to as the generator rate tariff. Your supplier agrees a set rate to pay you for the energy per kWh generated. It is important to say that the rate will change each year for new projects and will change in line with inflation. The amount of payments will be the same as what you would receive from FIT as well. They will paid to you for 20 years and perhaps longer until the system can generate enough energy.
Though the Feed-In tariff has come to an end and some of the electricity produced by your solar power will eventually go back to the grid. And since in the current legislation, it is illegal to be compensated for this. new system was designed. This is where the Smart Export Guarantee comes in to play.
“Rent a Roof” schemes have been discontinued due to the government’s removal of the FIT.
There is also another incentive called renewable heat (RHI). This can be used with ‘solar thermal’ systems which warm the hot water in your home. Payments are made for up to seven years and are based on how much heat that your system generates. If you own your own property situated in England, Scotland or Wales You can apply on the government website.
Smart Export Guarantee
This Smart Export guarantee is a good news if you are hoping to get your money back from the start of your investment. After the government announced the changes to the FIT and new projects, they were in doubt, however, the government is now able to provide an agenda to ensure what the future holds for the solar sector.
So, what is this Smart Export Guarantee? The final plans on the Smart Export Guarantee were released at the time of the announcement by the Government on the 10th of June, 2019. The Smart Export Guarantee demands large to medium-sized electricity supply companies , including SSE, EDF Energy, British Gas, npower, EON UK and ScottishPower (those with more than 150,000 customers) to provide the Smart Export Guarantee (SEG). Smaller providers can participate on the basis of a voluntary basis. Suppliers are already starting to offer SEGs, however all of them must to agree to terms for payment for solar power, wind power & others renewable energy imports before January 1st, 2020 by the date of the.
This is a good thing for solar panel owners since the program will in the end be market-driven, rather than subsidised. In the past , the Feed in Tariff offered a fixed rate set by the government. Instead of subsidies and guarantee, the new one will be an introductory rate. Once the new system is started to work, it’s certain that there will be competition among the energy companies to offer better tariffs in order to win your loyalty.
To benefit from the proposed Export Guarantee scheme, you must have an MCS-certified installation. Importantly, anyone who installed solar panels between the end of Feed in Tariff and the start for the new program will become eligible to participate in the new scheme.
The Solar Trade Association has been insisting that households be paid at a fair market rate for the power they provide to the electricity grid like all Generators in other industries are. There are two methods to determine fair pricing. One is through wholesale prices which is the rate that the market purchases electricity from to sell to you. In 2018, this was approximately 6p/kWh. The other is called the System Sell Price’ that was mentioned by the government as a fair value in their SEG consultation. This is the amount larger generators are paid in exchange for surplus power when they produce more power than they contractually arranged to produce. The annual average System Sell Price in the last year was comparable (5.4p/kWh) with the previous FIT export tariff that was 5.2p/kWh.
This is a fantastic change for those who are considering the installation of solar panels, but delaying doing so due to the demise from fees in Tariff. While prices have decreased significantly in the last decade However, the new program is also expected to become more flexible than the current tariff. The cost of solar falling by more than more than 80% since 2008 it was the ideal time to revisit the manner in which the payments were paid. Business and homeowners who install new solar panels will be guaranteed payment for power provided back to grids to enable the smart energy systems in the near future. This could be significant enhancement to the current Feed-in-Tariffs scheme.
Smart Export Guarantee Smart Export Guarantee will see electricity providers paying smaller-scale producers of energy for surplus electricity from homes and businesses that are then reintroduced into the grid. The new program could lead to the creation of an entirely new market encouraging suppliers to competitively bid for this electricity, giving exporters the best price while also providing the local grid with clean, green energy, unlocking greater choice and control for solar homeowners over purchasing and selling their electricity.
Currently, the government is obligated to electric companies to purchase power at a price above zero. The good news is that the electricity market is evolving rapidly and there are many suppliers who are embracing smart energy to create the most efficient, low-carbon energy system, and they’re seeking customers who want to participate. Companies early to uptake in the system’s new features include Octopus who are offering both variable and permanent SEGs Bulb who offer customers who produce their own electricity to pay for all electricity they produce and sell to the grid (This is for customers who are solar only that are storage-only, solar-only, or solar and storage co-located) and EON which is paying the first 500 new solar customers 5.24p per kilowatt hour (kWh) of energy that they export back to the grid , based on the assumption that 50percent of the energy generated is exported.
The more complicated new system is expected to take time to become established however there are savings to be realized that will grow as the large energy companies jump on board and start competing against each other.
A lot of people are asked if it is possible to install or even build your own solar panel system. Yes, it’s possible to do this and is more affordable than buying a solar panel. There are some things to take into account:
In order to take advantage of the new proposed export Guarantee policy, your must possess an MCS certified installation.This should be performed by a professional engineer to ensure that security standards are adhered to. It can be difficult to convince someone else to do this with a system they didn’t install themselves. Also, there could be issues when you plan to sell your home.
