I am in Michigan so installing contractors are limited. I would like help full comments and questions on the communication chain related to a solar install at my home. I will do my best to insert the info from my e mail chains here. However I am doing this from a cell phone which is problematic at times.
Hi Doug,
With your energy saving endeavors you can decrease the size of the solar array.* Or you can keep the size, bank credits, and use the credits to offset your heating costs in the winter.* Without shading and moderate assistance in brushing off snow this system will generate approximately 7,775kWh a year.* Most people won’t brush off snow unless the grid is down.
The battery bank size you request is quite large.* It is 38.4kWh of storage.* With a 60% discharge this will give you 23kWh of usable storage.* With an average usage of 400kWh a month/ under normal conditions/ you should be able to cut that usage in half when the grid is down.* This will give you almost a week of autonomy without any recharge from the panels.*
So here is a narrative and budget – This is minus batteries.* I have listed an adder for the batteries at the bottom.* Because of the high proportion of the cost that is the batteries I figured it would be best to list them this way.
24 – SolarWorld 285w panels – 4,480w system
- Outback Radian GS8048 inverter charger (8,000w inverter w/ 12,000w surge)
- Outback Radian load center #GSLC175-PV-120/240
- Patriot solar racking set to a 35 degree angle – 90’ from the home
Total cost for turnkey system (minus batteries) - $26,875.00
Batteries
8 – 8G8DLTP – 12vdc 265Ah batteries wired together as a 48vdc – 530Ah battery bank - $6,465.00
This is at least a starting point for us to narrow down what will make sense for you.
Sincerely,
Mark*
Mark yes I would like you to quote a turn key system. I am afraid of the cost and have an idea of what I can reasonably afford. But I want to here what the outcome is. The kw of storage is a really convoluted conversation. *We just made some big changes this week end to get ready for this. We bought a new energy star refrigerator and bought a propane dryer. The refrigerator should save us 300 kw a year in usage and the dryer about 60 per month. I am hoping to get to a sustainable 400 or less kw of consumption.*
Due to the crap production I am concerned the quantity of panels we are discussing here will not be enough in December that is why I am interested in the ins and outs of a high bread system.
*
All the math shows I need 1000 ah battery bank but the cost would be so limiting.
*
I want a 800 plus ah 48 volt battery system. It will be in my basement so it will need to be gel type or if you know of any other cost similar technology.*
Hi Doug!
Few things;
- The 280w panels are now no longer available – they are now 285w.* So 24 – 285 would be a 6.84kW solar array.* This should produce a little more power than your 640kwh a month usage.
- How many kWh’s worth of storage would you like?*
*- Did you want us to quote the installation?
Sincerely,
Mark
Mark,*
This is Douglas the family that visited you a few weeks ago.
*
I would like a proposal to consider cost options and start consideration for cost.
*
I would like a ground mount system. No roof mount.
*
The solar array will need to be 90 feet from the basement where the equipment will be placed.
*
I want a gel type battery backup because they will be placed in the basement. This will eliminate venting.
*
We have average ed 640 kw hours per month. *We have been changing all of our lights to led.
*
I would like an array of 24 280 watt solar world pv cells.
*
From everything I can read. I need a minimum of a 6000 watt inverter. *The inverter will need to capable of 240 volt output to power the well.
*
I want to explore the cost of it being grid tied so the power is not being wasted in open circuitry when the batteries are fully charged.
*
Their are many things to discuss here but I would like to see a proposed cost and itemized lists of components.
*
Please get back with me on this.
