Handles single daily need.114kwh of back up power,
Doh, thanks, i missed that.each of the bundle includes qty (2) of the 14.3KWH batteries.
Any thoughts on sizing my battery bank properly to the solar array?Doh, thanks, i missed that.
114.688kWh / 5h in August = 23kW of solar panels to charge from empty operating at 100% efficiency
114.688kWh / 2.66h in December = 43kW of solar panels to charge from empty operating at 100% efficiency

I see people talk about the price of a monthly utility but not talk about the price to replace solar system components.I'm weighing the costs of installing this system vs. paying the utilities company to bring in poles or underground wires. So far, my $40-50k solar costs are a LOT less than our local utility company which came in at close to $90k, plus I would have to pay for the cost of using the power.
A lot of people seem to like sizing 1:5 to 1:7 in panels to batteryAny thoughts on sizing my battery bank properly to the solar array?
I would have a 114kwh battery bank and (60) x 370-480w bi-facial panels. I calculated the panels to produce 430w which could potentially produce 25.8kw of power. I would imagine this is plenty of power to fill the battery banks but would love your input.
"Ain't nuthin' free in this world..."I see people talk about the price of a monthly utility but not talk about the price to replace solar system components.
If solar panels last 30 years, batteries last 20 years and your inverter last 15 years maybe you have a generator on site too?
what is the cost to replace and maintain those?
In my mind the cost of those is your monthly bill.
I live off grid and I do enjoy the energy independence, but it's definitely not free power.
You are looking at buying a solar system at a great time, it is way cheaper now then even 3 years ago"Ain't nuthin' free in this world..."
Its your plan, i'm just crunching your numbers.There's no way I would be using 114kwh per day. I'm thinking I would be closer to 30-40kwh
Cheapskate!$50k makes my wallet cringe.
I'm just messing with you of course Never say "No way I'd be using 114kWh" to an unknown moving target lol. But I really appreciate everyone's input, no matter how painful it might be to hear! ....Its your plan, i'm just crunching your numbers.
There will probably be a lot where we plan to build, at least that is what our friends are saying happens. I would like to keep my bottom row of panels at least 3-4' off of the ground. Maybe even designating the south facing portion of the house for roof mounts. I would want to make sure those panels connect to the same inverter and/or inverters so their production is the same. Reason being is I highly doubt I'd be able to fit 60-70 panels on my roof!Since you are in Maine, how much snow is on the ground usually during winter where you will be? That will make big difference in what you use for a ground mount.
