Solar Panel Prices 2021

Solar panel prices have decreased in price significantly over the last five to six years. Below offers an outline of what solar panels may cost in the current market.

In 2017, there were 709,000 UK installations of solar panels on homes, workplaces, and in solar farms. If this trend continues, 10m homes in the UK will be fitted with solar panels by 2025. Meaning two fifths of the electricity we’ll use as a country during summer will come from solar panels.

By installing a solar PV system on your home, you’ll save money on your electricity bills each year. The government will also pay you money for the electricity your panels generate, for 20 years after installation.

To have solar panels installed on your home, you’ll be looking at an initial investment of between £1,500 and £10,000 depending on the type of solar panels you get.

In this article, we’ll look at the cost of solar panels to purchase for your home, installation costs, how much you’ll save on your utility bills, and how much you’ll receive each year from the Government for having your system fitted.

Buy solar panels for your home

The payout from the Government for electricity produced by solar panels has caused some farmers to convert fields into solar farms. The money they make from the feed-in tariffs is more than they can make from growing food or raising cattle.

No wonder it’s become so popular. So, when you get a solar installer out to give you a quote on the cost of a solar PV system, what do you need to know?

The solar electricity facility installed neatly on your roof will be made up of individual solar panels. Each of the solar panels will cost you between £350 and £550. Each solar panel is around 4m2 and each one will output between 400 and 450 kilowatt-hours per year.

As you’d imagine, the more solar panels you have on the roof, the more electricity you’ll produce to power your own home. It also means that the cost of your installation will rise too but you can cover all or most of that cost over the next 20 years because you’ll be paying less for your electricity and you’ll get up to three forms of subsidy payments from the Government.

Solar panels – cheap for sale now compared to a few years ago?

The popularity of solar panel installations on homes and businesses continues to grow. It’s not just a British phenomenon though – other countries are seeing a similar surge in installations.
That, together with ongoing advancements in the technology behind solar panel production, means that if you’re looking for solar panels cheap now, UK installers will be pleased to help you.
If we turn the clock back to the start of the decade, the average price, for a solar power panels system suitable for a family of three would be between £12,000 and £13,000. In today’s market, you’d be looking at paying between £4,900 and £6,100 – that’s half the price of a few years ago.
With prices falling year after year, does that mean it’d be smart for a homeowner to delay investment in their own solar panels?

Solar panels prices 2021 – why should you invest now?

The minute you drive a car off the showroom forecourt, you know it’s lost a lot of value. That’s the reason so many of us either don’t buy new cars or we buy second hand.

With solar panels, it pays to think differently. A lot of people a few years ago had the same mindset and by waiting it cost them a lot of money.

How did they lose out? The price you pay for an installation is only half the story when you purchase solar panels for your home. In addition to saving money on your electricity bill, you receive payments from the Government under something called the Feed In Tariff (FIT) system.

Back in 2010, when the costs of solar panels were much higher, so was the value of the “Feed In Tariffs”. As the price of solar panels continued to fall, the Feed In Tariff remained quite high. This continued for a number of years, and the homeowners who had their system installed before 2016 continue to make a lot of money from their solar panel systems because their rates are locked for 20 years.

In 2016, the amount of money paid out by the Feed In Tariff system dropped dramatically. In late 2015, the Feed In Tariff offered 12.47p for every kilowatt hour produced (both generation and export – more on what that is very soon). From 8th February 2016, that dropped to 4.38p.

Let’s show what that means in the real world. If you got a 4kw solar system installed in December 2015, you’d get back around £475 a year in Feed In Tariffs. If it were installed on 8th February 2016, it would be £166. Over twenty years, the homeowners who got a February installation lost out to the tune of nearly £6,000 – a lot of money.

That’s why waiting might be a bad decision – although the cost of the technology is still falling, delaying your decision could cost you a lot more in the long run if the Government decides to slash the tariff again.

Solar panels – what is the Feed In Tariff?

You make money in three different ways with your solar panel installation. We’ll take a look at them here and calculate what these payments actually mean for a homeowner with solar panels.

Number one is the Feed In Generation Tariff.

With the Feed In Generation Tariff, your energy supplier actually sends you a fixed amount of money based on the amount of electricity your solar panels have produced in a month. You receive Feed In Generation Tariff payments once a month and you get this money as soon as your system is installed. Payments of the Feed In Generation Tariff carry on for 20 years after your installation.

Number two is the Feed In Export Tariff.

Again, this is paid by your electricity company and it’s for the amount of electricity you feedback into the National Grid. In other words, you get paid for the energy you don’t use because you’ve effectively generated it for the electricity company on their behalf. Payments of the Feed In Export Tariff carry on for 20 years after your installation.

Number three is the Domestic Renewable Heat Incentive Scheme.

The Domestic Renewable Heat Incentive Scheme (DRHIS) pays money to homeowners who install one or more of a wide variety of green electricity facilities – that includes biomass generators, ground source heat pumps, air-source heat pumps, and, of course, solar panels. Once you have been approved by the DRHIS, you receive an additional 20.66p for every kilowatt-hour of electricity your solar panel produces for seven years after it has been fitted.

There are some important things for you to know:

    • The base price of the Feed In Tariff (both rates) will be frozen at the amount offered per kilowatt hour for 20 years going up every year by the rate of retail price inflation
    • The rates above only apply to homes with an Energy Performance Certificate rating of D or higher. If yours is lower, your rates are reduced. An Energy Performance Certificate is the same certificate that estate agents provide you with if you put your home up for sale
    • Your installer has to be registered with the Microgeneration Certification Scheme (MCS) when they fit your system and they must report the installation to MCS in order for you to be able to qualify for the Feed In Tariff Scheme and the Domestic Renewable Heat Incentive Scheme.
    • You also have to apply to join the Domestic Renewable Heat Incentive Scheme. They have a set of rules that you will have to follow for the seven years after your system has been fitted. Each year, you have to contact the Scheme to report your ongoing compliance. To find out more, please check out the Government’s information page by clicking here.

Let’s look at all three incentives in one table to show where your payments will be coming from…

Time period Dates Feed In Generation Tariff Feed In Export Tariff Domestic Renewable Heat Incentive Scheme
Q3 2019 1 June to 31 August 2019 4.01p per kilowatt hour 5.03p per kilowatt hour 20.66p per kilowatt hour

Solar panels prices 2021 – do the numbers stack up for this?

It would be great if homeowners got the same level of Feed In Tariffs they got before February 2016. Unfortunately though, that’s never going to come back so it’s reasonable for you to ask whether it’s still worth it? Is it worth the upfront expense for the savings you’ll make over the next 20 years with a new solar power panel system?

Most UK homeowners install a 3kW system. Earlier, we saw that the investment required for that is between £4,900 and £6,100. Let’s half the difference and look at a system costing £5,500.

Every year, what you save and what you earn will be about 5% of the cost of your system – 1.5% of that will be in lower electricity bills, 1.4% of that will come from the Feed In Generation Traffic, and the rest from the Feed In Export Tariff. According to UK Power, the average 3-bed semi electric bill is £49 a month or £588 a year.

5% of £5,500 is £275 a year which adds up to £5,500 over the first 20 years. That’s the cost of your system covered. In addition, for the first 7 years, you’ll earn 20.66p per kilowatt hour from the Domestic Renewable Heat Incentive Scheme – so having solar panels on your home can still make you money.

Many solar power companies offer finance packages to allow you to spread your initial cost over up to 10 years meaning that you don’t have to have all the money upfront now to install your new solar panels.

Solar panels prices – are there any other costs?

Solar panel systems are designed to be low maintenance and capable of producing renewable energy for 25 years or more after installation. They’re also incredibly safe as manufacturers and installers have to abide by some of the strictest health and safety regimes across all industry sectors.

Every now and again, a solar panel may stop working. Your manufacturer’s warranty will cover this and, in most cases, so will your installer guarantee. Always make sure to ask.

In addition, if you’d like the peace of mind of having someone check over your system on a regular basis, there are solar power maintenance companies offering this for a fixed annual price.

Should my solar panel installer belong to any trade body?

Unless you know an installer very well and personally, it’s always safer to work with a company with at least one year’s trading history behind it. For further peace of mind, you might want to ask to speak to one or two existing customers – most reputable solar panel installers will be absolutely fine about your doing that.

You must also make sure that an installer you choose to work with is registered with MCS otherwise you won’t benefit from the Feed In Tariffs or the Domestic Renewable Heat Incentive Scheme.

Keeping your details safe…

We take the security of your data very seriously from the outset. Our web address is HTTPS. (HyperText Transport Protocol Secure) This is the protocol used to access a secure Web server. We use https:// as the prefix to our Web address rather than the common http://, so that your session is managed by a security protocol and the transmission of data is encrypted to and from the Web server.

Secure certificates (SSL Certificates) are in place. These are small data files that digitally bind a cryptographic key to an organisation’s details. These allow secure connections from a web server to a browser. SSL is used to secure the transfer of your data to our server.

Our server is protected by a firewall. Log in details are securely shared internally between employees.

Any personal data held in our database is encrypted. If there are any security breaches, your data is encrypted and therefore secure.

Each supplier to whom we pass your information in order to provide you with quotes has contracted with us to keep your data safe and use it only for the provision of a quote and, if selected by you, to provide the product or services you require.

We always have contracts in place with the companies that we pass your details on to both to ensure that they will keep your data secure and that they comply with the rules of the GDPR (General Data Protection Regulation) which we also operate within.
Please be assured – we will not use your details for marketing or use or pass your details to third parties other than as described in this statement without explicit consent from you.

Finally, please note that the transmission of information via the Internet is not completely secure. Although we will do our best to protect your personal information, we cannot guarantee the security of your information transmitted to our site; any transmission is at your own risk. Once we have received your information, we will use strict procedures and security features to try to prevent unauthorised access.

Lawful basis for processing your data

We rely on your explicit consent to process your personal data. This means that we ask you to consent to the following use of your data:

Business users only

We will email or text you about similar products and services. We will only do this if you haven’t opted out of receiving such emails or texts.

To create custom and lookalike/ similar audiences

We like to work with Facebook, Google and other platforms (“Platforms”) to reach out to you with adverts for Other Products. We also like to use Platforms to reach out to other people who might like to use our quote request service.

We do this in two ways. In both cases, your data, along with other data, is used to create a custom audience and/or a lookalike/similar audience. Whenever an audience is shared with a Platform, the data is first hashed and pseudonymised, meaning that any data within the audience that could identify a person is replaced with an artificial identifier. So, the process is secure. Also, we don’t share more data than we need to for the purpose of creating the audience.

Transfers of data outside the EEA (European Economic Area)

We share your personal data within our business and with data processors who can find suitable product and service suppliers for you. Your data will then be used to enable suppliers to provide quotations and potentially move towards a contract with you.

Some of the suppliers that may offer products and services to you are based outside of the EEA.

We transfer your data as detailed above with your consent.

Data Retention Policy

We keep your personal data for no longer than is necessary for the purposes for which it is being processed. This is to reduce the risk that it will become inaccurate, out of date or irrelevant.
We ensure that your personal data is securely disposed of when no longer needed.

What are my rights in relation to the personal data that you hold?

Your rights are embodied in the contract formed between us when you visit the website (as subsequently augmented when submitting your personal information and, if you are called, when speaking on the phone) and as contained in the General Data Protection Regulations 2018 – also known as GDPR.

If you have any questions or concerns please first read this section of the statement and then email our Data Protection Officer on, They will be pleased to assist before as well as after you may have provided personal information to us.

You may also write to our Data Protection Officers either at our registered office address stated at the outset of this statement.

If you need more information about data protection you might contact the Information Commissioner: see

The GDPR provides individuals with the rights in relation to personal information about themselves which is held by us as summarised in the table below.

Some of the rights are unlikely to be of practical use. For example, if you wish for a copy or correction or cessation of use of some or all of your personal data we, our suppliers and our other introducing companies are likely already to have eradicated it from our or their system given the short periods your date is retained and its limited use.

Nevertheless, the GDPR principle of transparency in particular provides you with the right to enquire and to be informed and we briefly set out all of the rights here. Further information about the rights and the circumstances in which they apply may be obtained from a number of published sources and from our fact sheets which are available on request.

Information Right – you may require us to provide a more detailed explanation of how we collect, process and use your personal information.

Personal Data Access Right – you may require us to provide an electronic copy of your data free of charge.

Personal Data Correction Right – you may require us to correct your personal information as held by us.

Personal Data Erasure Right – you may require us to permanently erase the personal data that we hold about you.

Data Processing Restriction Right – you may require us to stop using your data for particular purposes such as mailing or profiling.

Data Processing Objection Right – you may require us to suspend using your data if for example it is incorrect or you simply wish to withdraw your consent.

Data Portability Right – you may require us electronically to transfer your personal information to another supplier, for example to facilitate switching.

Automated Decision-Making Right – you may require us not to make decisions about you relying solely only on a computer decision.

Breach Notification Right – if in the unlikely event there occurs a breach of security which is likely to result in a high risk to your rights as a data subject, we must inform you without undue delay.

How else can we help?

Rights aside, if you have a change of heart and do not wish us to pass your information to potential suppliers or another introducing company please let us know immediately by email or, should we call you, during our phone conversation and we will remove your information from our and their systems.

You are not bound to enter into a contract with any supplier that provides a quotation to you and can unsubscribe from any communications related to your enquiry from them or us at any time.
