I have been thinking about the fact that a large percentage of the population, especially in Metro areas live in Apartment Complexes. This has always been a problem when it comes to install Solar, Powerwalls and even wall chargers.
The other interesting point here is that many apartment complexes actually have quite vast under-utilised roof space with no mechanism by which to fairly distribute the economic cost and benefit of solar and battery.
As a though experiment what does everyone think of the following?
1. Owners Corporation propose a Special Levy to raise the Capital Works funding required to deploy a 10-50kW solar array with or without multiple Powerwall batteries. Let's say you have a 12 Unit Residential Apartment Building with enough roof space for 100 panels this should generate an average of 120kW/h per day in energy. Couple this with 6 Power walls and you could offset a large proportion of the grid.
2. Tesla installs the solar system with behind the meter connections to each Lot within the Apartment Building. A centralised distribution board tracks exactly how many kW/h are consumed by each Lot. Excess solar generation is exported against the Common Area meter to the grid. Tesla would develop a special Gateway that orchestrates the power to each Lot, controls loads on for vehicle charging and ensures every kW/h is apportioned to the respective resident whether they are an owner or tenant.
3. Tesla invoices each Lot Resident per kW/h consumed behind the meter directly at a heavily discounted rate. Say for example, 12c per kW/h instead of the average 25c per kW/h. This means Residents can enjoy say an 80% discount in electricity bills.
4. Tesla takes a 10% commission on all payments and deposits the remainder into the Owners Corporation bank account and therefore makes a small ongoing revenue from the system. The Owners Corporation on the other hand can make 5 - 10% ROI on the initial investment.
Some numbers:
System cost: $60,000
Average Daily Generation: 120kW/h
Price per kW/h: $0.12
Yearly Revenue: $5,256
Tesla Margin: $525.6
Owners Corp. Revenue: $4730.4
Owners Corp. ROI: 7.88%
Assuming 15yr lifespan with 1% degradation per annum the whole thing would net itself out and cost essentially nothing. When it comes time to refresh the system, Tesla would come out and install everything again except the economics would probably mean an even steeper discount in rates to the Resident and thus driving down Electricity costs in the long run.
