Upgrading Your Inverter

If you have had your solar PV system for a long time, then you are most likely your inverter is suffering from one or more of the problems below. Over time, things degrade and this isn't any different for solar panel equipment, trees grow and things get dirty, all of this will be affecting your solar panel ouput. This is where a new inverter from SolarEdge could pay for itself, check out our upgrades page for more information.

Solar panels work when they are clean and free from dirt. Over time a build up of dirt, dust and even bird droppings can cause your panels to be less efficient.


Shade on a solar panel that is connected to an old string inverter can severly affect the ouput of your system. It covers the solar cells, limiting the electricity they produce.


Over time, with exposure to the elements, solar panels can degrade. Some panels can be affected more than others, but on an old string inverter it will affect the whole system.

Faulty Panels

You're only as strong as your weakest link. If one panel isn't pulling it's weight because of a fault, the rest of your system suffers to. Something a new inverter can rectify.
