Lol your grid tie systwm comes to 4.8kw if your (15*.375) is correct. We rip around 20kw a day on a AVG house in Aust. My folks shred through 30kw an that's just 2 people.
Given power used to be about $3k a quarter or $12k a year for them...it's only 3 years of bills to cover a 15yr battery. They already got 8kw of solar for 13k too. Not bad at all really, $45k for battery an solar, pays for itself in 4 years if your use is high enough. 11 years of savings before you replace the system.(aus dollars)
- 2Gkashmiri 6y agosounds good but i paid less than USD 1200 for the panels, inverter, cabling, installation. Our monthly power consumption is around 300Kwh in summers (no need for air conditioning) and double in winter months (need heavy heating but no electricity due to low supply/heavy snow). that gets to around USD 200-250 for a year. that gives me 22000/250=88 years of no electricity bills to repay this system. Note, my Kwh is USD 0.05 the country is india where due to USD exchange rate which is INR 73:1 USD.
- gtvwill 6y agoMy god I'm jelly of those prices. Aust is 27-32cents a kWh for grid power. About 1$ per watt for solar panels. If you feed back into grid you get paid 16ish cents per kWh.
- 2Gkashmiri 6y agoOh. We arent paid or anything, just the reading is supposed for a year to year and I have to pay just 10% of my last bill. Say I consume 1000kWh for a year and generate and sell to them 1100kWh, then I still have to pay for 100kWh at same prices. I could reduce my load on grid by going battery but that is very expensive and with lead acid the ROI doesnt reach as they get depleted in 3 years before any profit is made. Havent looked at lithium as its very expensive..... will see If the policy for net metering changes in future, I will preemptively buy another 5-10 kWh panels
