Customer Goal
Bob’s main goal was to provide his tenants with independent electricity and increase his property's future value. His tenants' main goal was to reduce their electricity bills because they had other expenses and 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 challenges at the site because the homeowner was well-educated and 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 and long-term savings, both for himself and 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 exceeded 2.45 times their electricity bills, which also affected consumption patterns and improved sustainability.
The 11.785kW system installed on Bob’s home for his tenant resulted in estimated savings 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 enabled up to 42% self-sufficiency, benefiting the customer by reducing dependence on the grid and lowering electricity bills over time. The best thing in this system was the feed-in tariffs: the extra generation fed into the grid and provided up to 58% in benefits, serving as an additional source of income alongside the savings. In Baldivis, as a certified installation company, we installed 10+ solar systems on homes' rooftops.
Installation Process
Installation Inquiry: Bob connected with the Solar 365 online platform. Bob was very stressed about his installation and about which system would work for his tenants.
Consultation: After receiving Bob's inquiry, Solar 365 learned about his needs and property details, including his residential address, roof type, number of stories, and electrical 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 the unwanted charges on them. The tenants were a family of five, and they already had other expenses, so they wanted a system that was compatible and 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 handled government approvals, so we applied for the customer's Western Power and Synergy approvals to ensure a properly verified installation, and we documented everything.
Installation: The installation was done after all the inspections and approvals. The installation was done by our in-house installation team and electricians, who were well-trained in their fields, and was completed in three hours of hard work with perfect placements, proper resource management, no wastage, and a clean installation.
