Solar Power in the home

or as we like to call it, POWER INDEPENDENCE….

Rising electrical costs and an unpredictable energy supply is both a burden and a worry for the Home and their owners. Not knowing if you will have power when you get home does cause some anxiety and you find yourself asking " will there be hot water to bath the kids" and I, "will we be able to make dinner", " will we be able to wash and Iron my cloths for work tomorrow"

How do we go about sizing a suitable system?

  • Firstly we will come to asses your site, check for suitable roof space and direction. Also check your Utility bill to give us a baseline understanding of your overall usage.
  • Before we finalise the size of the system we will give you solutions to reduce your consumption first- this will help you save on your total requirement.
  • We will measure your Peak Usage to determine the size of your invertor system.
  • Once we have collected this information we will be able to discuss your needs and ensure they meet with your expectation of the system.

FAQ

What is a normal sized house?

Well.. There is no normal house, but we have systems currently installed that vary from 3kW through to 9kW in residences.

Do I need batteries?

No, if you are looking to reduce your electrical bill only by supplying your own power needs during the day through Solar. A battery bank is used if you want to be independent of the Grid or as a back up if the Grid fails.

How can I get off the Grid?

We favour a step-by step approach, first reduce your usage by making changes to your heavy equipment such as Geysers/Ovens and Lights. Then together we will work toward this end goal. It is most certainly possible and extremely rewarding to be independent.

What does the Invertor size in kW mean?

This means that while using the Electricity through your invertor, the maximum load will be 3000 w. This means that you would need to limit items that draw higher energy such as Electric Ovens, Geysers. Also when using multiple items in the house, if used at the same time will exceed the inverting capability and overload the system.

Why does a system become overloaded?

When you exceed the capability of the invertor over a set period of time it will go into a fail safe and trip the system. For Example your house is running 1x Fridge ( 150w), Lights ( 100w), TV and electronic equipment ( 100w) = 350w or normal load: You then turn on the Microwave oven ( 1000w), Toaster ( 800w) and hairdryer ( 1500w) at the same time, your system will reach 3650W and overload the system.

How is the size of the Invertor selected?

Your Peak load will need to be checked, and after reducing your consumption through management such a changing heavy bulbs to low energy and LED bulbs the peak can be taken. You also then take off the high energy appliances such as geysers and Electric ovens to invest in a more economical sized system.

How do I calculate my usage?

Using a metering device such as an Effergy will enable to monitor and display your usage, this will give you an idea of the peak you are drawing and the total amount of electricity.
