Common Questions

Solar System Upgrades FAQs

Can I add more panels to my existing system?

Often yes, depending on your inverter's spare capacity. If the inverter is at its limit, we'll recommend an inverter upgrade or a second system.

Is it worth upgrading an old solar system?

If your bills have crept up or your system underperforms, an upgrade often pays for itself quickly through restored savings.

Will an upgrade affect my current feed-in tariff?

This depends on your retailer and tariff. We'll advise how changes may affect your arrangement before proceeding.
