We now have a PV-direct water pump solution for pool pumps, Polaris vacuum and well pumps up to 2 HP. The 1 HP solution is 4 250 watt panels into a device that takes the DC and creates 208 3-phase. Replace the pump motor with a 208 motor and off one goes. The HP of the pump dictates the # of panels needed. We like it here in the south as Utilities try to limit the size of residential PV and lots of folks have pools.
The pump solution is stand alone, does not feed back to the grid making it outside the guidelines. The biggest positive is we often have prospects that do not want to write a check for a large system but will for the pool offset, making them great prospects a year or two later when they have tasted the power bill savings
We are also starting to use the solution for chicken houses and the high volume fans that pull air through the chicken houses. Always something new :)

How 'bout a Tesla Powerwall? That way you can test it out first and let us know how it goes :)
Got any flexible, multi-application thin film out there?
How about PV-direct water pumping? That's going to be a hot topic for us in Cali. here pretty shortly.
Sounds like a great gig you have there. Thanks for being a solar educator and spreading the good word.

All great ideas!!
We do have S-5 both for racking and the PV kit. To Great point we do cover efficiency, passive solar, load shifting... We do have internships with install companies and the utilities. We have 5 different racking types and one ballast mount for hands on work. We have 4 on campus systems all with different monitoring (Tigo, enphase, egauge and SMA) while working on the mock roof we do tie off and observe a safety procedure. We also cover OSHA regs as part of class and the students get OSHA 10.
The battery ideas are good too. LION and such are needed for sure along with monitoring for those systems. I just did my first solaredge system and I agree that is a must.
We also need some design software. We have the pathfinder and solmetric software we use in class and we use PVwatts and those similar to that.
Much appreciated. I hope to build lab that covers as much as possible for use with students and our continuing ed electrical programs.

I would suggest a Solar Edge inverter system, some lithium batteries, an Aqueon battery system, a variety of safety equipment and trying to partner with a local installation firm for site visits, and possibly hands on work.

Hello all,
I was recently hired to be the full time electrical instructor at a local community college. In the second year of the class there is a 6 credit "renewable energy and habitat house" course. I have been teaching at this college as an adjunct instructor since 2009 teaching for 3 of the 7 local iron ore mines,the local paper mill as well as doing most of the NEC code update courses. During that time I ran a one year and a 6 month solar PV course. I have a fairly nice lab built for the PV course consisting of the following:
2 axis tracker
Fixed tilt pole mount
20'x16' mock roof with shingles and metal roofing
Enphase systems
(3) 700W SMA inverters
Outback setup
Xantrax 600v 80A charge controller
Magnum 4024 inverter (AC coupled goal with this)
Tigos
300W Morningstar on a demo cart
Couple Solectria inverter (not used much)
Trace 4024 (purchased in 99)
Trace DR 1524 that goes along with our 1Kw Bergy
Multiple battery brands and types AGM and flooded
Pathfinders
Suneye (2 210s)
600V Solmetric PVA
Racking, quickmounts standoffs, clamps nuts and bolts...
Modules include: 90W sunwize, Solarwolrd 175, REC 215W, silicon energy 190W, kyocera 210W, solar frontier 100W (I think 100W) AEE 95W, Dasol 15, 30, 135w.
Assuming I stay with this job for the next 25 years, which will take me into my early 60s and my goal, I will have a yearly budget to spend adding to this lab.
Here is the question, seeing what we have now what individual pieces would you add or what system would you build with the goal of community education or training electrical students and electricians.
Long winded but I am very interested to hear your ideas!
Have a good weekend and thanks!
Jesse
