FAQs

Do I need to do any maintenance on the system?

Yes, we recommend an annual maintenance check to keep your system safe and running smoothly. During this check, our team will perform updates, system tests and cleaning to ensure your system stays in optimal condition.

Why is my system showing lower-than-expected generation?

There are a few reasons your iSolarCloud system might be generating less electricity than expected:

  • Shading from trees, buildings or other structures
  • Dust or dirt on your solar panels
  • Weather conditions, like cloudy days reducing sunlight
  • Aging panels or decreased inverter efficiency

If your system drops to zero generation or shows sudden fluctuations, there could be an external issue, such as a supply problem from Enemalta. In these cases, our support team may need access to your system data to investigate and help get everything back on track.

How long do solar panels typically last at optimal efficiency?

Solar panels are built to last. Typically, they maintain optimal efficiency for around 25 to 30 years, giving you decades of reliable energy.

Who should I contact if the system stops working?

How to safely turn off and clean your solar panels

Before you start cleaning, make sure to switch off the DC isolator, in other words, the safety switch for your solar system. This step ensures no electricity is flowing from the panels while you clean. Once the panels are dry and spotless, you can safely switch the DC isolator back on.

Cleaning guidelines:

  • Clean when panels are cool, ideally in the early morning.
  • Use clean water only (no soaps or chemicals).
  • Never use high-pressure cleaners, as they may damage the panels.
  • Check that there’s no debris such as grit, sand or hard particles on the panels or your cleaning tools as these can scratch the glass.
  • Avoid letting water run over electrical components.
  • If you’re working at height, always use the proper safety gear.

Pro tip:
Remove bird droppings promptly with clean water and a soft brush. Avoid scraping, as this could scratch the glass.
