Customer Goal
Bob’s main goal was to provide independent electricity to his tenants and also increase his property value for the future. His tenants' main goal was to reduce their electricity bills because they had other expenses as well as a family of five. Also, with this installation, he wanted to teach his children about solar generation and sustainability for future generations.
The Challenge
Solar 365 didn’t face any specific challenge at the site because the homeowner was a well-educated person who cooperated with us at every step. It was a classic modern home, with reliable infrastructure and a single-storey tin house. The property was located within walking distance of the Baldivis Children’s Forest. The main reason for the solar installation was the tenants. The landlord was a nice and generous man who believed in sustainability as well as long-term savings, both for himself and for the tenants. The property was rented. The average monthly electricity bill was around $250.
Our Solution
The 11.875kW solar system improved energy generation. Solar generation was more than 2.45 times higher than their electricity bills, which also affected the consumption pattern and increased sustainability.
The 11.785kW system installed on Bob’s home for his tenant led him to an estimated saving of $3,715. This not only gave him electricity independence for his house but also provided lifetime savings of up to $92,883.
The high-capacity battery led to self-sufficiency of up to 42%, benefiting the customer by reducing dependence on the grid and helping lower electricity bills over time. The best thing in this system was the feed-in tariffs; the extra generation went into the grid and provided up to 58% benefits, which also worked as an extra source of income with the savings.
Installation Process
Installation Inquiry: Bob connected with the Solar 365 online platform. Bob was very stressed about his installation and what kind of system worked for his tenants.
Consultation: After receiving the inquiry from Bob, Solar 365 got to know his needs and some property details, like his residential address, roof type, house storey, and electricity phase. This information helped us to understand the customer's needs.
Customer Needs: Bob wanted a system that helped his tenants reduce their electricity bills and reduce the unwanted charges on the bills, because the tenants were a family of five, and there were already other expenses in the family, so they wanted a system that was compatible as well as pocket-friendly.
Site Inspection: After understanding the customer's needs and concerns, Solar 365 provided them with an 11.875kW solar system for their tenants that was confirmed after visiting their house and the roof, determining how many panels could be installed, where they could be placed, and the direction where most of the sunlight fell for the proper generation of electricity.
Approvals: Solar 365 was a CEC-authorized company that worked on government approvals, so we applied for the customer's Western Power and Synergy approvals for proper verified installation, and everything was in documented form.
Installation: The installation was done after all the inspections and approvals. The installation was done by our own in-house installation team and electricians who were well-trained in their specific field, and completed the installation in three hours of hard work with perfect placements and proper management of resources without any wastage and with a clean installation.
System Performance
The 11.875kW system boosted the renewable energy generation for Bob’s tenants and increased the property value as well. The solar production was approx 2.45x, and his savings were up to $309.58 per month. The system reduced carbon emissions, which were equal to 98–100 trees; this increased energy independence. The 30kW battery provided excess power at night for efficient use of electricity, which was stored by the battery during the day and used at night, also making it a great investment for the rapidly growing world.
