Various aspects to Solar System Installation Sizing

We go through a few various points that we consider when deciding on solar system sizing, ultimately the best way to determine what you need is by starting the chat now and letting us ask you a few questions and for us to give you an obligation free solar system quote.

Roof space

Some people are limited to the solar power system size they can install by their available roof space.

Budget

Vortex Electrical understands that not everyone has an unlimited budget when it comes to installing solar power. We listen to you and work closely with you to find a system size that will fit within your budget as well as providing you with the savings you are looking for.

Feed-in Tariffs Will Save You Money.

Feed-In Tariffs (FITs) reimburse you for any power your solar electricity system feeds back into the grid. This means that you are paid for the extra electricity your system feeds back into the grid when it generates more power than your home needs.

Retailers may offer a Feed-In Tariff greater than your current retailer , so ensure you shop around. Make sure you also compare the price you will pay for electricity consumed, as well as your feed-in tariff. Check your daily supply charge too, as this can vary widely between retailers.

Electricity usage

Before determining the best size system for your household, we look at your electricity bill to understand your usage. The current low feed-in tariff means that we also ask you about your lifestyle and the hours you spend at home during the daylight (solar power producing) hours.

Expectations

Do you want to cover your whole electricity bill, or are you happy just to halve it? Do you want to be able to cover both your summer consumption and winter consumption? Vortex Electrical will design a system to help you achieve your expectations.

Using a combination of the above factors, we will present you with the best options for solar power for your household.
