Should I Get Solar Panels? 2019/2020

A lot has changed in recent years for the solar panel industry, and with all the developments a lot of people are left questioning whether solar panels are right for them or not.

Solar Panel 101

There are two types of solar panel

The panels that most of us think of are photovoltaic solar panels, otherwise knows as solar PV – that’s the ones we’re talking about here. Simply put, they convert the sun’s rays into electricity.

Solar thermal is a different technology with a different set of costs and subsidies, so it’s important when you’re researching that you know the difference. You can find out more about solar thermal here.

Government subsidies for solar panels are over

Up until recently, most people investing in solar panels were eligible for a government scheme called the Feed-in Tariff, which paid solar panel owners for generating and exporting renewable energy. Those already on the scheme can continue collecting these payments until the end of their 20 years contract, but new installations will no longer be eligible.

Free solar panels are over too

When the Feed-in Tariff was operating, a lot of companies were offering to install solar panels for free on people’s homes so they could collect on the FIT payments. Given that the scheme is now concluded, there are no longer any legitimate companies offering this. If you want solar panels these days, it’ll have to come out of your own pocket.

Solar panels are more about daylight more than sunshine

The fact that the UK is hardly a sun worshippers paradise doesn’t actually matter too much for solar panels. Although a bright sunny day will certainly help, even on those overcast days, solar panels can still generate electricity.

Positioning is everything

To really get a worthwhile generation from your panels you’ll need a predominantly south-facing roof with minimal shading.

If you live in the south of the country, you’ll find that you have higher generation rates too, owing to the curse of shady skies up north. The same 4kWp system might be generating 4,200 kilowatt hours down in Brighton, while up in Scotland it only reaches 3,500 kilowatt hours.

How much do solar panels cost?

While there is a whole lot of variation between different types, sizes, and systems, we’d estimate that a 3-4kWp solar PV array bought in 2019 would be around £5,000 – £8,000 (including installation).

How much can solar panels save me?

According to the Energy Saving Trust, a fairly standard 4kWp system could save you between £85 and £220 per year, depending on how much energy you use, where you are in the country, and when you’re at home.

If you’re at home during the day then your solar panels will inevitably save you more as you’re using the readily available electricity from the sunny hours.

However, a battery can take these savings a whole lot further. Although the cost can range from £1,200 – £6,000 depending on the capacity and lifespan, a solar panel gives you the opportunity to take the power generated in the middle of the day when most people are at work, and use it in the evenings when you need it.

Think we missed something? Do you have a different opinion?
