About the Solar Estimate

About the Solar Estimate


The Solar Estimate is the value of the estimated yearly power generated for this property by a standard solar system. The solar estimate is based on the annual value a standard 3 kW and 5kW system could generate using the average retail power price of 0.2875c per kWh.

The estimate is calculated in partnership with Lynker Analytics using detailed digital models generated from Lidar data to generate a heat map of solar potential for every roof in the city. The models take into account the size, angle and orientation of the roof as well as shadows from nearby trees, buildings and hills. The heat maps allow you to understand where on your roof might be best suited to solar panels and also how you compare to your neighbours.
