Can I add more panels?

Despite the same challenges noted in changing faulty panels, there are a couple of options available:
Add a new solar PV system next to the original system - This new system can either use a string inverter system (one central inverter where panels are connected in series to the string inverter) or using a micro-inverter system (where smaller inverters are located under each panel). 
The advantage of this approach is that it doesn’t alter your original system, which means you can leave the old system running, without it being brought up to current standards. This is a good approach if your existing system is working well.
Remove your existing system and replace it with a new system - If your existing system is not working and you have limited space on your roof for another system. 
When replacing it with a new system, we suggest fitting as many panels as your roof can fit. This will ensure you have enough excess electricity for a battery (which can be retrofitted to any existing solar power system).
