13.3kW Solar Starter Package
Give a larger household solar design a closer look. MJM Solar’s 13.3kW Solar Starter Package is an option for Perth homes with higher electricity needs and enough suitable roof area. We assess the extra capacity against your actual use before recommending a system.
A 13.3kW solar system in Perth can be worth comparing when daytime cooling, electric hot water, a pool or other regular loads make a smaller array less suitable. Start with your bill and the times you use electricity, then choose the equipment around that evidence.

Plan Ahead
Extra panels need a clear purpose. A household with strong daytime use has a different opportunity from one whose demand starts after sunset. If you expect a new electric vehicle, additional air conditioning or a move away from gas, include the likely timing and size of those loads.
Compare the 10kW solar package using the same tariff and household assumptions. Ask how much of the larger system’s additional production your home would use directly, store or export. That comparison is more helpful than choosing the largest number that fits the roof.
Include the likely timing and size of these loads.
Inverter Selection
The solar array rating and inverter output are different measurements. The appropriate pairing depends on the exact inverter’s input limits, the proposed panel strings, whether a battery is connected and the requirements applying to the installation.
MJM will specify the inverter as part of the design assessment. If you are planning a battery later, say so early: future battery plans do not mean every solar-only configuration is suitable today.
Ask for the final array size and inverter model to be recorded together.
Compare the full installed scope: panels, inverter, mounting, electrical work, monitoring equipment where included, and any required connection work. A complex roof or switchboard upgrade can affect the total as much as a change in equipment brand.
Request the total payable with GST treatment and any eligible incentive shown clearly. Battery storage should have its own specified capacity and price. The quote should also distinguish panel product cover, panel performance terms, inverter cover and installation workmanship terms.
≈59 kWh / day
Illustrative Perth annual average
An illustrative Perth annual average is about 59 kWh/day, using the Australian Government benchmark. Actual output varies; request a site-specific monthly forecast.
Roof Planning
For illustration, 28 panels rated at 475 W total 13.3 kW. The final module choice determines the actual count and space needed. Roof shape, shade, access clearances and the usable sections of each roof face affect how the array can be arranged.
Ask to see the proposed layout before accepting the quote.
A design spread over different orientations should explain when it is expected to generate, as well as how much it could produce over the year.
Optional Storage
Storage can be considered where a larger array leaves useful daytime surplus and the household needs energy later. It should be sized from the expected surplus, evening demand and desired reserve, rather than from the panel rating alone.
Compare a complete solar-and-storage design with a solar-only option.
Explore solar battery storage. If blackout support matters, identify the circuits, power limits and equipment needed before choosing the configuration.
FAQ
Still have a question about your 13.3kW design? Call 0475 404 818 or send MJM Solar an enquiry.
Solar production changes with the season, weather and time of day. A large array does not provide overnight energy by itself. Review the household’s hourly usage and any battery proposal before making an energy-independence claim.
A replacement or expansion needs an assessment of the existing equipment and connection. Tell MJM what is installed now, and ask whether removal, recycling and electrical changes are included in the proposed work.
No. It depends on the extra energy you can use and the additional installed cost. Both designs should be compared against the same roof, electricity profile and future plans. See the 10kW solar package.
