Load profile

Essential power system load profile

To accurately design your ideal off-grid solar system and provide you with a quote, we need to understand your property’s power usage.

We do this by asking you to complete an Energy Load Profile in which you list all the appliances and utilities that use power with an estimate of their usage amount. Once this is completed, we can recommend the best system design and size for you.
