Inverter Upgrades


Unfortunately, Solar PV inverters can and do fail over the life span of your tariff creating a window of opportunity to increase yield for the same panel array.

 

Your Current Inverter

 

Of the hundreds of inverters we have installed over the years the majority will have come complete with a standard 5-year warranty with this being increased in 5-year increments if stated on your original quotation. Whilst it goes without saying that the inverter is the piece of hardware that will almost certainly fail at some point over the next 10 years or so, we would suggest waiting for your current unit to fail and then upgrade to a fully optimized SolarEdge system. So why upgrade?  

 

SolarEdge

 

The SolarEdge system utilizes optimizers which individually manage each panel within your array, helping to increase performance and maximise both output and generation. This solution is particularly useful in situations where partial shading is present such as a dormer window or tree. An increase in generation by as much as 20% can be achieved from the same roof space using your existing panels - view it in the same way as your car's engine can be remapped to increase its performance.
 

Optimizers can be retrofitted to any system but the starting point is the removal of your panels from the roof and fixing the optimizers to the PV mounting rail in required arrangement. With the roof 'naked' like this, roof hangers and rail fixtures can be checked - a spring clean if you will. Once the optimizers are in place, the panels can go back on with the end result appearing no different from the original array.

 

 

 

Will this benefit me?

 
The million-dollar question. We would suggest looking at upgrading from your current string inverter if your system is over 4 years old. This isn't to say your current unit is not performing well, it is more a suggestion your generation figures could be enhanced using this upgrade with the addition benefit of a new 12-year product warranty. 
 
It is also worth noting that each site would be assessed on a case by case basis, if it would not improve your yield, we will tell you.
