The thing to watch is the cost of the panels per watt AND voltage. IF you get the correct panels 2 should easily pump 10 GPM, my chart shows 11 GPM at 80 feet of head with 380 total watts and 95-100...

This sounds like a good system, now add 2 panels 185-190 watts and roughly 45-50 volts, and a racking system, you will have all the water you need at any time and more than you need most of the time....

You have stated that your well guy will buy your existing pump back. If there is enough value in that, a separate Grundfos system makes more sense to me. We are probably talking less money and the...

What burns my butt here is that the WPA (government) installed the lines and now they claim it costs x amount to maintain them etc. Sure it costs something to maintain them and my state is a not for...

What will the well guy give you for your current pump? It may be cheaper to trade it for a Grundfos SQF pump and add less components and cost. The soft start with the Grundfos will save some, and...

The simple pump might be an option for inside your house, but it's not what I would call real conductive for your well pump. Much easier to store a few containers of water than to pump it into...

The Grundfos pumps are a good pump, and there is also Lorentz. Lorentz is more modular, meaning that the pump end and motor are separate so if 1 fails you can replace just that part, not both. ...

For $4000.00 you can come close to a full system including pipe for a short run, but NOT a 100 GPM system. I just priced a system for a customer today at less than $3500.00 with 2 panels and at 100...

I second, third or whatever SMA. Another feature they have that may or may not interest you is the ability to go off grid easier than some. Expensive, but good customer support.

If there is a solar pump that will pump 100 gpm, that's a tremendous amount of water and will take more than a few panels. Most house wells are in the 10 gpm range.
The 1" pipe is standard and...

IF the 3 tanks are level then you would only need one float, but if they are not level that's where you need a float on the lowest and on up so the water will fill the highest tank. Otherwise the...

It can be a bit complicated and confusing, but basically to do this with 1 system isn't that bad. Are all the tanks on the same line? If so then you will need to put a pressure float system on the...

And just got a notice they are going to raise the rates by an average of 3.25% making my plan for an additional 4K of solar look even better.

I'm going to do the same thing only on a smaller scale, I currently have a 6K system with a Sunny Boy 6000 and want to add another 4-5K with a Sunny Boy 5000 and a 5K Sunny Island with a Outback...

Access charge-$22.00 per month to have access to the grid. Plus the following rates per KWH
first 500 KWH cost 0.2161
next 500 KWH cost 0.1168
next 500 KWH cost 0.1054
next 500 KWH cost 0.0799

I used to have a house with natural gas, never again. They raised the rate to put in meters that could be read from the car so their meter readers didn't have to walk, then raised them again to buy...

My utility credits my account .03 per KWH for any overage each month. I can't put any additional $ in to sell at that rate, but with current rates I could actually make that closer to .15 (the value...

$100,000 dollars an acre for wine, dang must be lots of winos (sp) around. Good land for cattle production (think $8.00 a pound steak) could be substituted for 10% of the cost, but then this is...

I'm close most months, but will be adding another 4K of panels this year to cover my winter useage, if all goes as planned.
The current system is on a roof with 4-12 pitch so doesn't do well in...

Sorry all my statements are at my tax accountant as my place is a ranch that gets to pay taxes :(. Actually they don't list nearly as much as your chart anyway.
My utility meter registers total...
