Hi lehua13, Sorry for the long time it took to answer but only Today I checked the forum. Here is my list: - 550 Gal polypropylene tank $180 on a scrap place - windshield washer pumps $7 each at Napa store. - 12V DC programmable Timer $62 online - Two 24V DC 165W Solar panels $535 each. At full Sun I get 22Amps after converted to 12V DC. - 8 Batteries 6V DC deep cycle from Sam's Club $78 each. They are wired first in series and then in parallel to get the 12V DC. Also, the controllers transform 24V to 12V before feeding the batteries. - Complete system with tubing and spray nozzles $18 at Home Depot - Miscellaneous plastic tubes, T splitters and etc maybe around $30 Please note that the solar panels and batteries also take care of the external lights, garage lights, backup power for 2 computers + 1 Dell server. So the cost of the solar panels and the batteries are the big ticket but also they do lots of things for us. I run 2 wires 12VDC direct to 3 UPS 1250W. Since their own batteries kicked the bucket I connected direct to our battery bank. It have just to say that it works wonders on our case as we are not restrict to the individual power of the small original batteries of the UPS backups. Whenever I can I add a couple more batteries to the bank as it is a good insurance during hurricane season. I am guaranteed to get at least two/year as my wife gives me a birthday gift! To do only the irrigation you only need a small solar panel and a couple batteries as the pumps, that we have, use very little Amps. Since my last post I have removed one pump from the system and we are doing the dripping irrigation by gravity using a programmable solar irrigation controller with rain sensor (BRXCTRSiRS). Got it from the same place I bought the timer last year. It works perfect and I saves Amps from my battery bank for other tasks as well as water (if it is raining it automatically overrides the programming). Here we are Amp driven because we can save on electricity from the grid and doing so we are paying for all this investment! - Our new project is a hydroponic Strawberry system but it is too hot and humid outside now so we are doing it very slowly and waiting for the winter! Good luck and, again, sorry for the delay in answering.

. I'm a big fan of finding new ways to do things . . . this one has me puzzled though. I perused the site a bit, and I'm not sure who / what is "behind" this thing. It sounds a little too good to be true . . . You pay a security deposit, then your local going rate for the amount of juice it produces every month => albeit locked at that rate for length of contract. If you do a 1 year contract how can it possibly be worth the installation / setup to just tear it out again ? PV panels are roughly $4 / watt now . . . you'll need them; some kind of mount, an inverter, some wiring done and an interface / permission of local utility. The installation of all this stuff and then wiring it up is not cheap / easy / fast; nor is the equipment itself cheap. I put in a 2.8 kW system 2 years ago; it ran ~ $ 30k . . got some incentives from the state and fed; but still a very sizeable investment. With the REnU setup; who pays for all the equipment and installation ? . . that's thousands and thousands of dollars that they're gonna install and let you use for however long for a $500 deposit ? I think the basic concept of getting this stuff more available to the general public is great . . in many ways for all of us. This REnU thing however; doesn't seem right . . . it sounds too good to be true . . . I'd make DAMN sure I knew quite a bit more about it before I got involved. I'd love to know if you find / hear anything more about it . . . Not trying to be a wet rag on it; but it doesn't seem to add up in my mind . . there's something more to it . . . than I've managed to see . . . . Bob

Disney, So you didnt like that idea. Here is a very simple idea that will work with one button push. (it would take me less then 10 min and $20 to set the whole thing up) All you need to add is a icecube relay (DPDT) and power its coil through an open relay, or power the icecube directly. Then you will splice the cable going to the CVA so the two legs switch when the icecube relay is activated. ( I can draw it for you if you like) Then assign a name (cooling). Then you can set a time and a speed for it. Valve rotates and pump comes on. Software is not perfect, but there are very few things I have not been able to achieve with this system, and it is miles ahead of the rest.

This and my basement are my next projects. I recently had my roof replaced and I wonder what happens if there is a leak after solar installation, would the solar company eat it or the roofing company? How are you protecting the panels from squirrel or bird nesting? Is your attic now hotter or cooler with panels on top? Is the big inverter better than the micro inverters, was there a cost difference on your package for the big inverter? Are you expected to clean the panels yearly or is the company offering that service? Did that company have a battery bank system what was the cost difference?
