Increase your Solar Generation

Upgrade Existing Solar

Over time we tend to use more electricity.  Energy prices also go up and so our bills go up. You've already installed solar. What options do you have to bring your bills down?


Back when the solar industry was in its infancy, most solar arrays used string inverters. Today, there is a great way to upgrade existing solar using the latest technology if you want to increase your solar generation.

Are you using an old solar inverter?

If you feel that your solar array is in need of a system upgrade or if you suspect your system is under-performing, please schedule an appointment with our service team.

Solar Inverters

Inverters play an critical role in feeding the electricity produced by a solar system to the grid. Solar panels use direct current (DC) electricity and the inverters convert the DC electricity to an alternating current (AC), which is the type used for your home. Choosing the right inverter for your home can mean a difference up to 20% in your system's production.

So, what if your solar array has a string inverter?

Why you should upgrade your inverter?

Unfortunately with string inverters, if one of your solar panels goes out, then the rest of the system goes down. This occurs because string inverters treat a group of panels as if it were a single large panel, meaning any problems with one panel are felt across the entire string. The good news is, the solar industry has evolved over the last 10 years and if you would like to generate more power, upgrading your solar system from string inverters to optimizers would be a great idea.

  • The old inverter is coming to the end of its useful life (10-15 years)
  • Your roof has seasonal shading issues
  • Solar system is pointing more than one direction
  • Inverter has stopped working altogether (and may be out of warranty)
  • Upgrading your existing solar array.
  • You want advanced inverter functions like energy 'time of use'  and back up energy storage

Advantages of upgrading existing solar

Unlike the conventional solar PV inverters that were available some years ago. SolarEdge inverters have a 12 year standard warranty and roof mounted Optimisers have 25 year warranty, giving you not only better generation performance, but a far better manufacturers warranty. Here are some other facts to remember:

DC to AC conversion

  • Individual panel level optimization significantly increases overall energy harvest
  • Unique fire safety features give you peace of mind
  • Panel level monitoring makes for efficient remote diagnostics and reporting
  • Path to upgrade your existing solar panels to higher wattages as desired
  • Easier solar operations and maintenance and solar service in the future.
