| 25 400W solar panels at $0,08/Wp =$800.00 solar panels bought in bulk metal poles and brackets $275 10 EVE 334AH 3.2V= 10,680 kWh $70.30 =$700.30 batteries bought in bulk Enernet Power Router components $290 (I left out 2/3 of components because this is such a small installation and needs no 4x25 Gbps internet) Cables $230,50 Metal enclosure $61 Install fee 5 hours two people $23 per hour = $230 ============================== $2,587.80 So your "capital cost of solar right now of 1$/W" is 0.26$/W 10000 x $1W nominally installed =10000 kwh per year times 30 years = 3000,000 kWh total power yield $2587.80/300,000=$0.00862333 per 1 kWh LCOE 30 years
$2587.80/500,000=$0.0051756 per 1 kWh LCOE 50 years These numbers are of day prices of today. Currently the battery and solar prices are high because of the high oil and gas prices of the US/Israel/Lebanon/Iran/Ukraine/Sudan wars, there is a steep battery and solar panel price rise.
The overal LOCE is still hand-wavy in that several costs might happen in the 50 year of operation:
Drop of 20% solar panel yield by breaking glass, cost of cleaning the panels, cable replacement, accidental electronics wear en tear, extra maintainance labour cost.
Also, I doubt you need a loan to pay for $2582.80. If you did at a compound 3% interest rate with you would pay over 50 years, $11,344.67, more than 4,3 times than if you payed up front (from an online calculator, if you payed off per month than just the interest it would be lower). But whoever is right, you'll certainly stay under $0,01 per kWh from solar and round trip storage cost in batteries. If you are lucky, it will be almost half that, $0,005 per kWh. To heat your apartment and drive all over the American continent with your electric car you'll need more than 10kW for an average US midwestern house. |
