Find solar panel installers in St Helier quickly and easily

Finding the right solar panel fitter 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 keep you happy throughout the entire lifespan of your solar PV system.

Make sure any installer you select is MCS-certified. Even aside from the assurance certifications provide, it can be important in providing the right grants like the Smart Export Guarantee (SEG) and the social housing decarbonisation fund. You can inquire about the existence of a certificate by using the MCS helpdesk by referencing the address and technology type which helps you verify your installer.

Comparing prices is essential to understanding whether you’re getting the ideal price. You can compare the costs based on a few different factors including:

    • System size
    • Whether you’re installing on-roof or integrated solar panels (Integrated solar panels in St Helier can cost more than on-roof and require more labour).
    • Estimated solar output/efficiency
    • Brand and model numbers for your panel system
    • Whether the solar panels can fit your home

That’s why comparing suppliers is the best way to understand prices and options while ensuring that you’ve picked a reliable solar supplier.

How many solar panels do you need in St Helier?

So, how much are solar panels in St Helier? Generally, they cost about £5,000 – £6,000 for a 3kW panel system which can power a one-bedroom flat. However, this may not be suitable for everyone. Here’s how you can calculate more specific solar panel prices in St Helier.

Trying to figure out how many solar panels you need can be tricky, but the main deciding factors are household size and energy consumption. The average 2-3 person household uses approximately 2,900kWh of electricity annually, so let’s use that as a baseline.

Cost of solar panels in St Helier
House sizeAnnual electricity consumptionNumber of solar panels (250W)Number of solar panels (400W)Consumption level
Flat or 1-bedroom house< 2000 kWh2 – 42 to 6Low
3-bedroom house2000 – 4000kWh4 – 66 to 11Medium – low
4 or 5-bedroom house4000 – 6000kWh7 – 911 to 16Medium – high
5+ bedroom house6000 – 8000kWh10 – 1516 to 21High

A 6kW solar system is recommended for a home with over five people, while an 5kW solar panel system is typical for a home with four people. A 4kW solar panel system is one of the most common sizes for domestic photovoltaic systems, as it suits homes with 3 to 4 people.

The quantity of solar panels you need will depend on whether your solar system is 3kW or 6kW, and the size of solar panels you will use. For example, if you install a 3kW solar system using 250W panels, then you need 12 solar panels. A 6kW system would need 24 solar panels.

The number of solar panels you require will be influenced by the desired amount of electricity generation, whether it's the entirety of your electricity needs or a portion of it unless you plan to store any extra energy in a battery. Although solar battery storage prices can add to your overall costs, they help you make use of solar energy more efficiently and in the absence of sunlight hours.

Are there grants for solar energy in St Helier?

There are numerous available solar panel grants in St Helier.

While you may not always be eligible to get entirely free solar panels in St Helier, there are several schemes and solar panel grants available. These can greatly reduce the cost of solar panels.

One that you might have heard of is The Green Deal. This is a government policy that aims at helping you make energy saving improvements to your home and find the best way to pay for them. 

A green deal assessor will visit your house and make a report suggesting energy improvements such as insulation, changing your heating system, fitting double glazed doors and windows, or applying some low-carbon energy generating systems like solar PV panels or heat pumps. You will then get in touch with a Green Deal installer and be granted a loan which should be paid back through your energy bills afterwards.

If you are considering installing solar panels or a solar thermal system in your house, then it is a good idea to do some research about this scheme and see how you can benefit from it.

When you request quotes the solar installers can help you determine if you are eligible for a green energy fund in St Helier.

It’s also important to research the latest information since grants get discontinued all the time, like the Feed in Tariff scheme (FiT).
