I just put 20 x 300watt panels 6kw in total with 2000 amps of lithium
batteries at 48 volts with a 10KW LS pure sine wave inverter 2 Morning star
100 amp charge controller’s best thing I ever did, We have enough power to
run without sun for 4 days in a 4 bedroom house in Australia, This cost
about $30,000 But I do this for a job so it would be double that retail or

It has the plans and explanation there.
Solar like other renewables ‘can’ be expensive. But renewables can also be
installed cheaply – depending on how much power you want to produce.
It’s not always about the money. Let’s face it if everyone replying to this
video had megabucks, would you not like a system like this? Too much is
made of “how renewables are to save money” (same as electric cars).
A big part for some people is the reduction in CO2. Nissan advertise their
leaf as ‘Zero Emissions’, not ‘Saves You Money’. Governments are committed
to trying to reduce CO2. It seems people are more interested in their own
personal wallets and not what kind of world they are leaving for their
My modest 3.7kW wind solar system will probably never payback what it cost
me and it doesn’t totally remove my reliance on grid power. But has it
reduced my Carbon footprint AND grid powered bills? Yes.

Assuming the a 200W PV panel cost $400 USD in buck. Using the solar formula
sizing, it would take an estimated 30 200W solar panel for a 20 kwh system.
$12000 EXCLUDING inverter, charge controller, solar structure, solar cable,
electrical housing, installation fee and GST.
Little bit over-engineered for the weight of those panels, I think. Plus,
are you guys telling us this cost $120,000-130,000? Perfect thing for bored
teens to vandalize, I think. A miracle if these pay themselves off, ever.
This is bullshit.
Love these for mobile/portable/emergency/backwoods applications where they
clearly show their value. But as a practical matter for fixed operation
where mains power is readily available, just how-long is the payback
period? Where is the tipping point in Watts where the cost is worth the
wait for the break-even point, taking into account ALL costs to purchase
and install hardware, replace batteries, and maintenance? Tax ‘credits’ be
damned. A 100% tax offset over years would be much better.
@evo86ya $6.50 dollars each watt, so that depends on the consuption you
have the ammount you’re gonna spend, so the cost of the project in this
video (20,000 watts) was $130,000 aprox but that was just the cost of the
panels, you have to add the costs for the wiring, inverters, probably
batteries and a few more items, so yeah it’s a little expensive.
One Pump @ 10 Hp would require 7,457 watts. $1 per watt is about the
cheapest you can buy solar, plus the wires, inverter, etc. Cost would be
$10,000, and require at least 1,000 square feet, or about a 20 x 50 foot
area. With that said, check the motor performance, it probably consumes
less power than the rated horsepower. I’m assuming it runs steady for 8
hours. You might use an amp meter (it just temporarily clamps around the
wire) check the power usage while running.
