What is needed for an accurate residential solar power project estimate

You can request a solar power cost estimate to determine if a solar energy system is a cost-effective option for your home. Before a residential solar power home installation can be customised to your specifications, accurate data must be collected from a number of sources.

Required information for a solar power project estimate

• Energy needs: current consumption, energy bills
• Roof: type, age, angel to the sun
• Property: to determine if a ground mount is preferable
• Location: to assess amount of sunlight

When you call a solar power installer, their energy experts look at a number of elements, including your energy needs, your roof, your property and your location.

Energy needs
Knowing how much energy you have used and are now currently using determines the number of panels required to meet the energy needs of your household. It also helps provide data to project future needs, giving you the flexibility to add to your solar power system as your needs increase.

Roof
Your roof must be capable of bearing the weight of the solar panels and mounting system, plus snow accumulation. So an older roof may need to be updated before an installation can go forward. The angle of the roof also influences the amount of solar energy collected.

Property
For those homeowners with larger properties, there’s an option to have a solar system installed on the ground instead of on the roof.

Location
Solar irradiation varies for different locations. Knowing this value is an important part of building a reliable estimate. You can get an idea yourself of the amount your Victoria location receives by using the Victoria Solar Rooftop tool. It’s designed to provide accurate information however there are no guarantees. Working with a professional solar power company like NetZero Solar is the best way to get the most accurate information.
