[RE-wrenches] PV Tracker - Best available?

Given 310# snow load in the Sierras, what are some suggestions for a superior pole-mounted tracking system? Right now I'm considering DHSolar, but I'm unfamiliar with the product. Eric Stikes GoodSun Solar A 501(C)(3) CA. Non-profit Corp. NABCEP PV Pro 001.530.798.3738 (cell) www.GoodSun.life

This was my first recommendation to the client, to avoid tracking. But they really want a tracker (they're trying to keep up with their neighbors who have one). My engineer steered me to GMI trackers and those look very robust but are too pricey for this client. Eric Stikes GoodSun Solar A

Yes i do a lot of repairs but i will not install them, i prefer no electronics and motor drives seems to be the failure point. Zomeworks has none of this. Jerry On Oct 3, 2015 12:38 PM, "jay" wrote: > Have you looked at array technologies? > > jay > > peltz power > > > >

Hello Eric, With the low cost of PV solar modules, I would like to know why anyone would choose to track the sun? It cost's much more and is a maintenance issue compared to adding more PV modules to make up the difference. Tracking winter gain is about 10% and summer about 40%. If there is no

We have used zomeworks passive trackers in snow load, high wind and have not had any issues, i have seen some that were over loaded and still they have no issues. Jerry On Oct 3, 2015 8:49 AM, "SunHarvest" wrote: > Given 310# snow load in the Sierras, what are some

Bill's point is well made, and equally relevant in heating dominated regions. These typically are northern latitudes, where winter days are shorter, and mountain regions, where severe winter weather keeps people indoors, meaning more lights, more indoor activities and more

I see. Well then you need something heavy duty up there. I can heartily recommend the DH tracker as it is built on the same technology as their satellite trackers. I have installed quite a few of their satellite antenna trackers in the 90’s. Well built. They are still using a picture of one of

I have some up in that area and given winter angle, no issues. I have seen some issues with cheaper modules getting water between the frame and glass causing issues. Jerry On Oct 3, 2015 8:49 AM, "SunHarvest" wrote: > Given 310# snow load in the Sierras, what are some

Re: [RE-wrenches] PV Tracker - Best available?

Tracking not specific to the high Sierras but to Larry's point: In cooling dominated regions, the loads are shifted into the later afternoons. Of those 10% winter gains and especially the 40% summer, half is in the morning when it makes much more sense to put the additional cost that would go to
