I have panels around 11 years old using the FIT and am very well rewarded
How does the efficiency of these panels compare with the older ones and can you change panels and stay in the FIT regime
Hi Robert!
It’s fantastic to hear that you’re benefiting from the Feed-In Tariff (FIT) with your solar panels! As your panels are around 11 years old, you might be curious about how their efficiency stacks up against newer models and whether you can replace them while staying within the FIT scheme.
Summary:
FIT, or Feed-In Tariff, is usually made up of two components: generation and export. Generation is the big one; some people received well over 55p/kWh they generated! The export component was much lower (around 4p/kWh) and typically applied to 50% of your production.
Upgrading Your System
It is possible to change your equipment (some rules apply), usually on a like-for-like basis. Here are the best steps you can take (I have done all of them):
1/ Add a Battery: This does not affect either your generation or export but significantly increases your self-consumption, saving you lots of money!
2/ Add More Panels: As long as you keep your original inverter, this does not change anything on your FIT but will increase your generation and improve your battery usefulness.
3/ Get on a Smart Export Tariff: This can, in some circumstances, increase the amount of money you get from export, but these gains may be offset by losing your export component.
Efficiency Comparison
Older Solar Panels:
Panels from 11 years ago typically have an efficiency range of about 14-16%.
Over time, all solar panels experience a slight decrease in efficiency, generally around 0.5% to 1% per year.
Newer Solar Panels:
Modern solar panels boast efficiency ratings of 18-22%, thanks to advancements in technology.
They also tend to have better performance in low-light conditions and may come with improved warranties and durability.
The biggest difference is their output. Older panels may have an output around 225 watts, while the latest panels we install are usually 440 watts. So an old 16-panel system might produce 2600Wp, whereas an equivalent system today would produce 7040Wp. Unfortunately, FIT looks at the output, so you would not be able to change all 16 panels to these new ones!
Staying in the FIT Scheme
The good news is that you can usually replace your solar panels and inverter and remain in the FIT scheme, but there are a few important points to keep in mind:
Like-for-Like Replacement: To continue receiving FIT payments, any replacement panels should be a like-for-like swap. This means you shouldn’t increase the capacity of your system beyond what was initially registered.
Notify Your FIT Provider: Always inform your FIT provider before making any changes. They’ll guide you through the process and ensure everything remains compliant.
MCS Certification: Ensure that any new solar panels and installation work are MCS certified. This maintains the integrity of your FIT agreement and guarantees that the new panels meet UK standards.
Documentation: Keep all documentation of the replacement process. This includes invoices, MCS certificates, and any communication with your FIT provider.
By upgrading to newer, more efficient solar panels, you can potentially generate more electricity, reduce your energy bills even further, and contribute more effectively to reducing carbon emissions. Just remember to follow the proper channels to keep enjoying your FIT rewards.
