As the concerns about environmental protection continue to grow, more and more people are installing solar panels on our homes to generate our own power.
Photovoltaics, also known as solar panels (PV) take advantage of sunlight’s energy with photovoltaic cells, and convert it to electricity.
Fortunately that for those located in UK The cells don’t need direct sunlight to function They can nevertheless function even in the dark but less electricity will be produced.
However it is true that it is worth noting that the Met Office recently reported that April 2020 could be the hottest April ever recorded and the solar power sector reporting its highest-ever production for electricity within the UK at 12:30 on the 20th of April.
In the current energy market there are no bargain switches. Price cap offers are the most affordable. If this is changed and they’ll change you so that you’re able to save. Their service is free until they change you.
How do solar panels work?
These solar cells can be placed between two layers of semi-conducting material which is usually silicon. When light hits them electrons are ejected which creates the flow of electricity.
When solar cells are combined, they form solar panels when multiple solar panels linked together create an array of solar cells.
To ensure that solar panels get the maximum amount of light, it is recommended to put them on a south-facing roof but west- and east-facing roofs can also be used.
Solar panels must be pitched at an angle Between 10 to 50 deg with the best angle being somewhere between 30 and 40 deg. It is also important to ensure that there aren’t any buildings or trees nearby which could put the panels shaded.
Most solar panels are placed on roofs, however you can also put them on the ground or on walls or even to put solar tiles on the ground. However, be aware the solar tiles are not as expensive and usually cost about two times the price of panels.
If solar panels are installed with an inverter, it will also be fitted to convert the electricity produced from direct current (DC) to an alternating current (AC) that is the most common type of household appliances.
What are the advantages?
The main advantage of installing solar panels is that you’ll lower your electric bill. If the solar panels you have installed are large enough, you could be able generate enough power to power your entire house.
Another advantage is that you’ll reduce the carbon footprint. It is said that the Energy Saving Trust says a typical solar PV system at home can save between 1.3 or 1.6 tons of carbon each year, depending on the location you live in the UK you reside.
Do solar panels impact the supply of electricity?
If the solar panels have been properly installed and your system is properly installed, it should effortlessly switch from using the energy the solar panels generate to utilizing energy generated by the National Grid when the panels aren’t producing enough. You shouldn’t notice any change in the electricity you get.
You can make use of solar panels with your regular energy tariff that’s why you don’t need to inform your energy provider. You’ll use less energy from the Grid and consequently have lower costs. However, you must look around to ensure that your rate is adequate (along as your gasoline bill).

How much do solar panels cost?
The cost you pay to install solar panels is contingent on the roof’s dimensions as well as the kind of system you pick. Solar panels aren’t expensive, but prices have slowed over time and for some, it’s an affordable price to be paid for the environmental benefits that it provides.
According to the online service Green Match, one of the most popular options is a solar panel with a power of 4kW system that is comprised of 16 panels and takes approximately 29 square meters on the roof. This will generate enough energy for a house with a family (three to four persons) but you may still require electricity through the Grid.
How long will it take to recover the cost?
Based on the dimensions the solar panel and the amount of money you earn from exporting excess energy towards your National Grid (more on this below) You can expect to pay back the costs of installing solar panels in about 15-25 years as per Green Match.
While bigger systems are more expensive however, they produce more energy and could save you money over the long run. So a solar panel with 5kW will pay for itself in fifteen to twenty years. for a system with 4kW, it would take between 16 and 22 years, while the 3kW system will take between 21 and 25 years.
Earn money with solar panels?
The fed-in-tariff (FiT) scheme ended for new applicants on March 31, 2019. However, homeowners who had installed solar panels prior to this date and were able to apply to the scheme may still reap the benefits.
The scheme allows cash to those who generate their own electricity using solar panels or other renewable technologies.
If you don’t meet the requirements to receive the Feed-in Tariff may be eligible for Smart Export Guarantee (SEG) scheme, which was introduced in the beginning of 2020. With the scheme, you will receive a payment for any surplus renewable energy that you export for National Grid. National Grid.
All licensed energy companies that have 150,000 or more customers have to offer at minimum the Intelligent Export Guarantee tariff. smaller companies can offer an option to offer a tariff on a voluntary basis.
You’ll be qualified to participate in SEG SEG program if you produce electricity using solar PV panels, as well as some of these
Wind turbine
Hydro
Anaerobic digestion, where organic matter can be broken down absence of oxygen to create biogas that can later be used to generate fuel
Micro-combined heat and power where electricity and heat are produced simultaneously by the same source of energy.
Your system must be less than 5MW in capacity or 50MW for micro-combined power and heat. It should also be certified as part of the Microgeneration Certification Scheme (MCS) or similar.
Additionally, you’ll require an electrical meter installed that can give half-hourly readings to ensure that your supplier is aware of the amount of electricity you’re exporting.
What is the procedure for SEG tariffs function?
If you sign up to an SEG tariff, it is possible to receive a fee for any extra power you generate, which is redirected back to the National Grid. However, unlike feed-in tariffs you won’t receive all the power you generate, therefore payments will likely be less.
Energy providers can choose the price they charge and the duration of their contract as well as whether the tariffs are variable or fixed. Fixed SEG tariffs pay a fixed amount per kilowatt hours (kWh) in electricity exported during the term of contract.
A variable tariff is one that has price fluctuations based on the market demand (but prices can’t drop lower than zero). Therefore, it is important to compare the various tariffs available.
It is important to note that you are not able to receive both feed-in tariffs and SEG payments. However, you can opt-out of the feed-in tariff program in case you prefer SEG payments.
What should you consider prior to deciding on solar panels?
If you’re considering installing solar panels it is important to determine the roof’s appropriate in terms of whether it’s large enough and how much sunlight it receives.
It is also important to consider the size of solar panel system you require. It is crucial to make sure the capacity is large enough to satisfy the energy requirements of your home however, you must ensure you don’t have large excess.
It is also possible to consider installing an energy storage system that will store the energy that your solar panels produce. This can allow you to store the electricity produced in the daytime to use at night, allowing you become more self-sufficient and decrease the amount of power you consume on the Grid.
While you’re not usually required to get planning permission to install on solar PV systems it’s also advisable to inquire with the local authority in case there are any restrictions , for instance, if, for example, you reside in a listed property or a conservation zone.
Also, you should contact your insurance company for your home to confirm that they will insure solar panels. You should also find out the need for your premiums to be altered.
Also, ensure that you obtain several estimates from various companies to evaluate the costs of installation. It is recommended to search for an accredited installer through Microgeneration Certification website.
How do you maximize the use from solar panels?
If you decide to go in the direction of installing solar panels be sure to read these suggestions to help you are getting the most value from the panels:
Utilize more electricity in the daytime solar PV systems are the most efficient during daylight hours. Therefore, take into consideration doing tasks like washing or operating the dishwasher in the daytime and not at night. If you’re usually working in the morning, built-in timers on appliances could help.
Take a look at other renewable technologies If you’re capable of it, it could be worthwhile to combine solar PV panels and other renewable technologies, such as thermal panels, heat pumps as well as wind turbines.
Install an energy storage system as stated above, this will allow you to store the energy you generate during the day for utilize at night, and reduce the requirement to draw power to power the Grid.
Reduce energy waste: Simple steps such as shutting off the lights when they are not in use, or taking shorter showers and making sure you are draughtproofing your home will help reduce the amount of energy you consume.
Clean your solar panels It’s essential to clean regularly your solar panels. You can purchase solar panel cleansing kits or install automated cleaners that function somewhat like sprinkler systems. You can also hire a cleaning service to take care of the work for you!
