Solar Panels in London

Installing solar panels in London can help you save money on your bills, generate an income, and support London’s target to reduce its 1990 CO2 emission levels by 60%, by 2025.

London has more than enough sunlight to make solar panels work efficiently, and the mild temperatures are ideal in preserving solar panel materials.

Solar panel system sizes can be customised to satisfy different energy demands and roof sizes, and the surplus energy you produce can be introduced into the national grid and generate an income, thanks to various solar panel grants and schemes in the UK.

If you prefer a precise quote for solar panels in London, you are more than welcome to fill in the form at the top of this page and you will be contacted by up to four of our specialist suppliers. They will provide you with their respective offers, with no obligation to accept.

Is It Worth Getting Solar Panels in London?

Yes, it is worth it to get solar panels in London. Over the years, the price of solar panels has fallen constantly, reaching an all time low record in recent years.

Despite the price fall, solar panels have still quite high setup costs. On the other hand, if initial setup costs may represent a barrier in the short term, the benefits of solar power in the medium and long term will surely make the investment more appealing. In fact, average users in London save every year £180 on their electricity bills.

What’s more, is that homeowners can now earn money for surplus energy exported back to the grid through the Smart Export Guarantee (SEG).

There are numerous pros and cons to solar energy, and it is important to educate yourself before investing in solar.

    Save on electricity bills
    Low maintenance costs
    Sell unused electricity with the SEG
    Renewable energy source
    High initial costs
    Weather dependent
    Storing solar energy is expensive
    Uses a lot of space

Combining solar panels with solar battery storage systems can improve savings even further. In fact, the electricity generated during the day, can be used also while the solar panels are not working, avoiding to source from the national grid.

Finally, another aspect to consider, which may be also the most important one, is the environmental one. By installing solar panels in London, not only will you contribute to reducing the emission of CO2 globally, but you will also reduce fine particles locally.

How Much Does it Cost to Install Solar Panels in London?

The price of a solar system will depend on several factors, such as type and size of the system chosen, and the material of the panels. How many solar panels you need, will depend on your energy consumption, roof size, as well as your budget.

Therefore each installation will have different costs. A 5kW solar system is the most common size in the UK, which averages at £3,000 - £8,000.

Solar thermal panels instead, which convert sunlight to heat water, cost on average £4,000.

Can I Get Free Solar Panels in London?

Unfortunately it is not possible to get free solar panels. It was possible to get free solar panels in England and Great Britain in the period between 2013 and 2019, under the Green Deal Agreement. Solar panel companies would cover all costs of installation and maintenance but would retain the Feed-in-Tariff payments paid by the government for the produced and exported solar energy.

Since the closure of the Feed-in Tariff, another solar panel incentive came into force in January 2020 called the Smart Export Guarantee. This deal will with most probabilities make it even easier to break even, and in the long run can ensure quite good earnings.

Earn Money with the Smart Export Guarantee

The Smart Export Guarantee is effectively a replacement of the Feed-In-Tariff in the UK. Similarly to the old system, the deal will enable homeowners to send surplus energy generated through their solar panels back to the national grid.

In the past, the government offered a fixed tariff that was valid for the entire length of the contract - usually 20-25 years. With the new deal, contracts can be negotiated short-term and with different operators. Users will be able to choose the provider who bids the highest fare, and there are usually no exit fees from the contracts but rather a period of notice.

Estimating the earnings for the exported solar energy under the Smart Export Guarantee is a little difficult as it depends on the efficiency of your system and the energy operator you choose. In addition, extreme adverse weather conditions, such as a rainy summer or a winter with heavy snows, will affect the performance of your system. However, solar panel owners in England usually earn £600 a year for electricity sold.

Becoming eligible for the Smart Export Guarantee scheme is very easy. You will have to provide the energy operator you plan to make a contract with, with a proof of identity to verify who you are, a proof of address and a proof of ownership of the solar system. You will then have the possibility to negotiate between a fixed and a variable fare.

After that, once the documentation gets approved and the contract signed, you can start exporting. It is important that the solar system gets installed by a certified supplier. The energy operator you sign the contract with, might in fact ask for a copy of the system’s certificate to verify that your system complies to standards.

Where to Buy Solar Panels in London

Finding the right solar supplier can eat up a lot of your time. Moreover, since the required investment is quite significant, you want to make a good purchase which will make you happy during the entire lifespan of the solar system. Therefore, you should compare different suppliers and their respective options to make sure that you pick a reliable and certified installer.
