Why Choose ESE For Your Voltage Optimiser Installation
As expert solar installers, we know how disappointing it can be when your solar panels just aren’t quite performing the way you hoped. It may be that they require cleaning or maintenance, or it may be that your solar panels just aren’t reaching the energy output you would expect because of wasted voltage or shading.
Whatever the reason, ESE can help you solve the issue, but if it’s the last reason and your solar panels just aren’t performing as you would have hoped, then voltage optimisers could be the answer for you.
A voltage optimiser is designed to sit behind each solar panel in your array, and maximise the amount of energy it produces by squeezing out a few more watts from each cell. Considering the optimiser will be working away constantly throughout your solar PV system’s life, that’s a lot more energy output from each solar panel over the next 25-40 years.
If you think a voltage optimiser could support your solar PV system, then contact ESE Group today, and we’ll be able to talk about whether a voltage optimiser is right for you and your system.
Voltage Optimisers: How They Can Help
There are plenty of reasons why your solar panels might not be performing as they should – be it shading preventing a panel from reaching its maximum power output, or dirt or debris preventing one or two panels in the system from performing as they should.
The problem in a traditional solar system is that this can actually affect the overall energy output of your entire system. With voltage optimisers attached to each panel, though, the overall energy output won’t be affected, and the individual solar panel – even if it’s dirty or shaded for a time – will produce more electricity for your home or business than it otherwise would have done without an optimiser.
Essentially, the main appeal of voltage optimisers is that they act as a sort of insurance policy for your system. Weather conditions not ideal? Dirt or bird droppings affecting a solar panel from performing at its best? Voltage optimisers will ensure that your energy output doesn’t drop significantly, and that one poor-performing solar panel doesn’t spoil the rest.
How Do Solar Panel Voltage Optimisers Work?
Advanced solar technology, known as Maximum Power Point Tracking (MPPT) is deployed. This technology allows optimisers to track the maximum power of each solar panel as it produces solar electricity. It then regulates the voltage across the entire system so that the maximum power is sent to the inverter to be used by the appliances in your home.
This ensures that your entire system is producing the maximum amount of power it can on a given day, because your optimisers will be working hard behind the scenes to ensure every panel is producing as much power for your home as it can.
Types Of Voltage Optimiser
Discrete DC Optimisers
Discrete DC optimisers are, in our professional opinion as solar installers that have worked with optimisers for years, a great option. They can be fitted to pre-existing systems, so if you already have a solar installation and didn’t opt for an optimiser when you first installed your system, it isn’t too late.
With these types of optimisers, each solar panel has an individual, tiny optimiser attached to the back, and they work to increase the energy output of each panel, so more energy is sent to the inverter to be used in your home or business.
Better yet, not every solar panel in your array will need one. If there are one or two panels that are more prone to shading than others, for example, then you can fit these optimisers to just those panels that need the support.
This is one of the main advantages of discrete DC optimisers over other optimisers – because you can add them after the solar panels have been installed, you can actually monitor your solar system’s energy output and performance first, identify any issues with specific solar panels, and then only attach optimisers to those that need them. This saves you money, and ensures you’re only installing voltage optimisers that are necessary.
We partner with only the best discrete DC optimisers on the market, so if you decide this option is best for you, ESE Group can carry out the installation for you and support you in making your solar panels even more efficient for your home or business.
Smart Panel Optimisers
Smart panel optimisers are also known as integrated DC optimisers, because they are already installed on the back of each solar panel and it comes complete as one unit, so the optimiser element is already built into the system. Not all solar panels have this – it’s a special feature for a specific type of optimiser integrated panel.
Of course, if you have a smart panel optimiser already installed at the back of each of your panels then you won’t need an additional optimiser – your system is already doing what it should.
For those looking to install voltage optimisers with a pre-existing solar system, this isn’t an option because the cost will include the price of new solar panels, too, which will obviously mean replacing every solar PV panel in your solar array unnecessarily.
If you’re looking for a new solar panel installation for your home or business, smart panel optimisers can also prove to be a more expensive option depending on the solar installer you work with and the solar panel manufacturers.
If you go for this option, do your research first.
Microinverters
Microinverters sit on the back of each solar panel, rather than being a single, larger inverter that all solar panels send their energy to before the energy is inverted from DC to AC to be used by appliances in your home. They do the same job as other inverters, but they usually have an optimiser built in.
This is, by far and away, the most expensive option on the list though, and they do have some issues like not being appropriate for every solar array – especially if you use a solar battery – but they are incredibly efficient.
Again, if you choose this option, research is required before you go ahead with the installation.

Do I Need A Voltage Optimiser?
In truth, no, not every solar system needs a voltage optimiser, because some solar PV systems simply work perfectly without any help because they sit at the perfect pitch with no shading and can always achieve the maximum energy output regardless.
But that’s not likely to be the case for every home and business owner. Many people can stand to add voltage optimisers to their solar array because they’re designed to help when conditions aren’t optimal.
Most solar panels will get dirty, end up in shade for at least part of the day, or not perform at maximum potential 24/7, therefore, most solar panel systems can benefit from voltage optimisers.
What Our Voltage Optimisers Offer
When you work with ESE Group, you’re working with quality. We only align ourselves with the best voltage optimisers on the market, meaning you benefit from expert installation of top-quality products.
Besides that, the voltage optimisers we install will:

Voltage Optimiser FAQs
Some of the most common questions about voltage optimisers are answered for you here…
That’s a question only you can answer. Do you find your solar panels aren’t performing as they should? Are you struggling to get the maximum energy output out of them each day? If so, then voltage optimisers will support your system in performing at its best so you get more out of your solar PV panels, and it’s probably worth the investment.
If your solar panels are performing exactly as they should, then investing in voltage optimisers is probably not necessary.
That depends on the voltage optimiser type you choose and the performance of your panels right now.
With discreet DC optimisers, though, you only need to install them on individual solar panels that aren’t performing at their maximum.
There’s some debate about this in the solar community, but ESE comes down firmly on the side of the debate that says yes, you’ll save money with voltage optimisers, but no, it won’t make a HUGE difference to your bank balance.
With that said, voltage optimisers are designed to squeeze every last drop of usefulness out of your solar panels, meaning you rely on the national grid for your electricity less, and therefore you’ll save money on your energy bills. That just makes sense.
And even though it won’t save you hundreds each year, it will still contribute to reducing your energy bills and helping you reach the breakeven point, where your solar system has paid for itself in savings, that much quicker!
Yes, voltage optimisers are perfect for being fitted retroactively to improve your system even more.
