PowerNet envisions that there would be an increase in roof top solar panel installation on residential households in the next 5–10  years.

If you are considering solar panels on your roofs, here are some questions that might be useful to ask your solar provider / installer  before installing solar panels on your roofs:

  • How do you determine the best solar system for my house?
  • What is the best solar panel angle for my house?
  • What is the expected solar energy profile for my house, and how does this compare on my load profile?
  • Does it really save me money in the long term?
  • How does grid-tied solar power work, how do I ‘sell back’ energy, and is it economical to do so?
  • How do I heat up my hot water with excess solar energy generate?

Tips: You can request your energy consumption data from your energy retailer.

Thinking of installing solar panels on your roof top? You will need to apply for a grid connection which can be found here.

The approval process would be much easier if the grid-tied inverters are from one of the list here.

How it Works

The diagram above shows a grid connected solar system. When sun is shining, electricity generated by the solar panel is consumed by the load and any surplus solar energy generated can be exported back to the grid or be redirected to other loads such as the hot water cylinder.

Grid-connected solar energy will usually not be enough to supply a house in the event of an outage.
