As the concerns about protecting the environment grow, more and more people are installing solar panels on our homes to generate electricity on our own.
Solar panels, also called photovoltaics (PV) take advantage of the sun’s energy by using photovoltaic cells, and convert it to electricity.
Fortunately for us located in UK The cells don’t need direct sunlight to function They can nevertheless function even on cloudy days however, less power will be produced.
While this is true it is true that there is no doubt that Met Office recently reported that April 2020 could be the sunniest on record and the solar power industry revealing its highest-ever production of electric power in the UK at 12:30 on the 20th of April.
In the current energy market there are no bargain switches. Price cap plans are the cheapest. However, if the price cap changes and they’ll change you so that you’ll save. The service is free until they change you.
How do solar panels function?
These solar cells can be placed between layers of semi-conducting materials typically silicon. When light strikes them electrons are ejected which creates an electric current.
When solar cells are merged, they create solar panels when multiple solar panels linked together make an array of solar cells.

To ensure that solar panels receive the most light possible, it is recommended to install them on a south-facing roof however west and east-facing roofs can also be used.
Solar panels must be pitched at an angle that is Between 10 to 50 deg with the ideal angle being in between the 30-40 degrees. It is also important to ensure that there aren’t any structures or trees nearby which could put the panels shaded.
Most solar panels are placed on roofs, however there is the option to install them on the ground or walls or even to install solar tiles. However, be aware the solar tiles aren’t as expensive and usually cost about twice the amount of panels.
When solar panels are installed with an inverter, it will also be fitted to convert the power generated from direct current (DC) to an alternating current (AC) which is the most common type of household appliances.
What are the advantages?
The main advantage of installing solar panels is the fact that you can reduce your electricity bills. If the solar panels you have installed are large enough, you might be able generate enough electricity 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 for your home can save between 1.3 up to 1.6 tons of carbon every year, depending on the location you are in the UK you reside.
Do solar panels impact the supply of electricity?
If the solar panels have been properly installed the system will change seamlessly from using the energy the solar panels generate to utilizing energy that comes from National Grid when the panels aren’t producing enough. You shouldn’t notice any change in the power supply.
You can make use of your solar panels in conjunction with a regular energy tariff that’s why you don’t need to inform your energy provider. You’ll use less energy from the Grid and have lower costs. However, you must check around to ensure your electricity tariff is adequate (along as your gasoline bill).
How much do solar panels cost?
The amount you spend for solar panels is contingent on the roof’s dimensions as well as the kind of system you pick. Installing solar panels isn’t expensive, but prices have decreased over time and for some, it’s a minimal cost to be paid for the environmental benefits that it provides.
According to the online service Green Match, one of the most commonly used options is a solar panel with a power of 4kW system that is comprised of 16 panels and takes approximately 29 square meters in roof area. This will generate enough energy for a house with a family (three to four persons) however, you might require energy via the Grid.
How long will it take to recover the cost?
Based on the dimensions that your solar panel and the amount of money you earn by exporting excess energy towards National Grid National Grid (more on this below) You can expect to pay back the costs of installing solar panels after fifteen to twenty-five years as per Green Match.
While larger systems cost more 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 require between 16 and 22 years, while the 3kW system will take between 21 and 25 years.
Earn money with solar panels?
The feed-in tariff (FiT) scheme ended for new applicants on March 31, 2019. However, those who have installed solar panels prior to the date of this announcement and who were able to apply to the scheme may still be eligible for.
The scheme allows cash to those who generate their own power through solar panels as well as other renewable technologies.
If you don’t meet the requirements in the tariff for feed-in may be eligible for Smart Export Guarantee (SEG) scheme, which was introduced in the beginning of 2020. Through this scheme, you will be compensated for any surplus renewable energy that you export into 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 ones can provide an option to offer a tariff on a voluntary basis.
You are qualified to participate in SEG SEG Scheme if produce electric power using solar PV panels, as well as one of these:
Wind turbine
Hydro
Anaerobic digestion, where organic matter gets broken down absence of oxygen to create biogas, which is later utilized as 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 an equivalent.
Additionally, you’ll require an electric meter that is able to provide readings every half hour so that your supplier is aware of the amount of electricity you’re exporting.
What is the procedure for SEG tariffs function?
When you sign up for an SEG tariff, it is possible to receive a fee for any extra energy you produce that is redirected back to the National Grid. But, unlike feed-in tariffs you won’t receive all the power you generate, therefore the amount you pay will be less.
Energy providers can choose the price they charge for their services, the term of contract as well as whether the tariffs are variable or fixed. Fixed SEG tariffs are paid a set amount per kilowatt hours (kWh) in electricity that is exported during the duration of the agreement.
A variable tariff can have changing prices based on the market demand (but prices are not able to drop lower than zero). Therefore, it is important to shop around and evaluate what’s on offer.
It is important to note that you are not able to receive both feed-in tariffs and SEG payments. However, you are able to opt out of the feed-in-tariff scheme If you prefer SEG payments.
What should you consider prior to deciding on solar panels?
If you’re thinking of installing solar panels it is important to determine what kind of roof you have in good condition in terms of whether it’s large enough and how much sunlight it receives.
You’ll also have to determine the right size solar panel system you’ll need. It’s crucial to ensure that the capacity is large enough to satisfy the energy requirements of your home and also ensure that you don’t have large excess.
You might also consider installing an energy storage device that can store the energy generated by your solar panels. This allows you to store the electricity produced in the daytime to utilize at night, allowing you become more self-sufficient and decrease the amount of energy you consume to power the Grid.
While you’re not usually required to get approval for the construction on solar PV systems it’s a good idea to inquire with the local authority in case there are restrictions – for instance, if you reside in a listed structure 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 whether your premiums should be altered.
Make sure to obtain several estimates from different companies to compare the costs of installation. It is recommended to search for an installer who is certified through Microgeneration Certification website.
How can you maximize the use the solar panel?
If you decide to go by installing solar PV panels review these suggestions to help you benefit the most from these panels:
Utilize more electricity in the daytime The solar panels will be the most efficient during daylight hours. Therefore, take into consideration doing chores like washing dishes and operating the dishwasher in the daytime and not at night. If you’re typically away at work, built-in timers for 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 previously mentioned, this will allow you to store the energy produced during the day and be used at night, thus reducing the need for energy generated by the Grid.
Reduce energy consumption: steps like turning off the lights when they are not in use, or taking shorter showers, and draught-proofing 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 cleaning kits or install automated cleaners that function somewhat like sprinkler systems. Alternately, you can employ a cleaning service to handle the job for you!
In today’s market for energy there aren’t any cheap switches. Price cap plans are the cheapest. However, if the price cap changes and they’ll change you so that you’ll save. The service is free until they make the switch.
