1 taking your park off the grid

2 overview WHERE WE VE BEEN: solar panels on common facilities WHERE WE ARE: solar panels on homes / cabins WHERE WE ARE HEADED: solar and batteries on homes / cabins WHERE IS THE FUTURE: solar and batteries on common facilities

3 WHERE WE VE BEEN: solar panels on common facilities

4 solar panels on common facilities 16kW Geelong 38kW Lyndarum 46kW Berwick

5 solar panels on common facilities some price ideas: 46kW (184 panels) = $58K 36kW (144 panels) = $45K 16kW (64 panels) = $19k average $1,200 per kw location: North (premium) East (morning) West (afternoon) go big!

6 moore s law price: 2012 paying around $2,600 per kw 2014 paying around $1,900 per kw 2018 paying around $1,200 per kw efficiency: 2014 quoting around 14-18% 2018 quoting around 15-22% capacity: 2014 each panel was 250W (4 panels = 1kW) 2018 each panel may be 300W+ (~3 panels = 1kW)

7 generation spread over the year

8 return on investment lets run some numbers 1kW = $1,200 purchase 1kW may generate around 1,200kWh of electricity per year 1kWh may cost you at the gate $0.20 1,200kWh x $0.20 = $240 per year $1,200 per 1kW earning $240 per year 20% annual return on investment ~5 year payback on investment

9 return of moore s law on investment in 2014 we estimated around 7-8 year return on investment in 2018 we are working on numbers around 5-6 years go big! generate more than you can use feed it back to your embedded network on-sell at a premium

10 oh, did I mention the environment greenhouse gas emission reduction calculations used are 1.17kg of CO2 per kwh generated on our example of 1,200kWh/year = 1,400kg of CO2/year 46kW (Berwick) generates = 55,200kWh saves 64,500kg of CO2/year 38kW (Lyndarum) generates = 45,600kWh saves 53,350kg of CO2/year 16kW (Geelong) generates = 19,200kWh saves 22,500kg of CO2/year car emissions 6km produces 1kg of CO2 you do the math!

11 WHERE WE ARE: solar panels on homes / cabins

12 solar panels on homes/cabins

13

14 offer deployment options: greenfield build roll out 100% variation take-up around 30% group buying purchase around 15% purchase options: capex depreciate on your balance sheet opex lease on your p&l power purchase agreement buy power at agreed rates

15 greeenfield capex deployment Lifestyle Ocean Grove 220 homes with 2kW solar system we included the extra cost with a lift in the home purchase price we are buying at $2,400 per system delivering an electric only community no gas smooth the North (premium) East (morning) West (afternoon) electricity generation across the community

16 benefits to resident support cost of living: reduced power bill (25-30%) avoided cost for residents rebate on feed-in tariff of $0.12kWh value add to home/cabin return on investment for the homeowners is equivalent to our projected return of around 5-6 years. due to the avoided cost and feed-in tariff & solid buy price we were able to negotiate

17 benefits to operator what s our business? operator benefits reduce kiosk size reduce parent meter bills reduce critical peak demand at parent meter on-sell feed-in electricity at a premium future proof your park through infrastructure mitigate rising energy costs at 2kW it s a conservative roll out - we may move to 3kW in future solar panels on cabins can feed directly into your embedded network by-pass the cabin meters. sell your green credentials people care about sustainability: eco-tourism

18 WHERE WE ARE HEADED: solar and batteries on homes / cabins

19 add batteries to the mix

20 what makes a good battery? capacity how much energy the battery can hold depth of discharge how much energy can be used before recharge round trip efficiency loses less power each time its used and recharged chemistry Lithium Iron Phosphate (LiFePO 4 ) versus Lithium Nickel Manganese Cobalt Oxide (NMC) warranty location length and terms of warranty Indoor only versus outdoor/indoor

21 what can batteries do

22 wake up numbers time! solar and battery system: 3kW solar array + 5kWh battery Volume price of $10,000 solar alone reduce bills by 1/3 solar & battery reduce bills by 2/3

23 return on investment 3kW solar = $3,600 3kW solar + 5kWh battery = $10,000 return on investment: triple the costs double the return investment return around 10%+ model excess generation on above with 200 deployments to provide enough excess generation to power all our common facilities!

24 active energy management intelligent batteries can be simply programmed to feed & store at appropriate times intelligent batteries are increasingly self-optimising power profile to feed & store linked to weather forecasts, smart-phone app, manual over-ride create a micro-grid decentralised clean energy sharing network via a connected community we are modelling energy independence around 80% (summer) to 60% (winter)

25 moore s law again Price (solar & batteries): 2014 paying around $18, paying around $10,000 (3kW solar array + 5kWh battery) efficiency: : exponentially increasing capacity: exponentially increasing it s only going to get better and cheaper

26 WHERE IS THE FUTURE: solar and batteries on common facilities

27 onsite battery farm? we are modelling energy independence around 80% (summer) to 60% (winter) with home solar & batteries deploy a battery array to get truly off-grid? the extra 20% needed to get truly off-grid may mean an additional 70%-80% investment on initial outlay the numbers to go truly off-grid don t stack up yet cost of land to deploy battery array reduced density on land increased infrastructure
