Default Solar

I was wondering if anyone in North Texas area has purchased a home solar panels(photovoltaics) system. The only solar equip supplys seem to be the following
Ebay,Northern Tool, Harbor Freight, Frys, Amazon and web based mfg.

Also curious about the solar evacuated tubes with heat rod used for home solar hot water . Just hoping to find a local supply point
thanks
Additonally thanks NTEAA and members

I notice that some diy people buy solar cells from ebay then frame,solder, and encapsulate to make solar panel. The same people then make youtube about their experience and process. Me personally think that I would just get solar panels and not diy a solar cells unless special application. For example residential home rooftop seems less labor/work to just purchase solar panels and not cells.

Stay far away for Ebay, Harbor Fright, and Northern Tool for any type of solar panels or equipment as it is over priced junk from China.

Where in NTX are you referring too? RE is not popular in TX because energy prices are extremely low, no NET METERING LAWS, or state incentives except on the Left Coast Island of Austin TX. Most utilites in TX will only pay wholesale prices for excess, and many will not even allow a GTI sytsem to be connected.

Most of the equipment is through installers in NTX but there are a few suppliers in Dallas area.

As for DIY panels I strongly recommend you do not try to do this. As they will fail in a very short time and with prices in the collapsing market you can buy factory panels at less cost and they come with warranties. DIY panels cannot be used in any code compliant installations or qualify for FED tax credits. You will want UL or ETL listed panels...

I somewhat agree about Harbor Freight
However, I do not understand the rest of you statement. Ebay is lousy sometime because you do not know what you get til you get the item.

I do live in North Texas DFW and I can drive to where ever for solar panels and related materials.

how much are you looking to purchase (in terms of kwp)?? and are you planning on grid tied or stand alone???
I buy directly from a manufacturer in China and my last purchase was about a year ago. best price you can get for best quality, but I am not sure what it takes in terms of import duty to the US, I shipped mine to Europe and had to pay 20% VAT.

How much will $4000- $5000 get. I am thinking about 200watt /230watt with enphase micro grid tie inverters.

they go about a $1/wp from the manufacturer but this seems to be a really low quantity and I am not sure if it would be worth dealing with the shipping/customs etc (it may become worth the trouble at ~10kw)...you are probably going to be better off to find a seller based in the US...I haven't purchases photovoltaics within US, but found this on google after a quick search (I don't know the company and have never done business with them, so if you are going to consider them do your research prior purchasing):

I am not familiar with enphase micro grid inverters, but aren't they a pricey solution?? why not a standard grid tie inverter?

Micro inverters are great if you get different size/power panels when you buy from different vendors over time. They are an ideal way to build up a PV system without getting into too much debt.

perhaps they will work for you, but from what I can find online they are priced around $200/unit(200wp)...so for a 5kw system you need about $5k worth of enphase inverters whereas a regular inverter will run you about $2.5k for the same power.
