This is true, and you are also limited to a grid-tie only system, but it does allow you to purchase small quantities of panels and build up your system as you can afford it.

Enphase isn't the only manufacturer of micro inverters. There several others that sell in the US, and a variety of inexpensive ones available from China.

TX Cotton I advise you to call your Utility provider like OnCore or whoever your provider is and check out their policy with GTI systems. Then follow up by putting paper and pencil to it and run the numbers.

You are in TX like me, I am on OnCore and just locked in my rate for 3 years @ $0.086Kwh which is dirt cheap. The thing about TX is we do not have Net Metering Laws or state incentives. OnCore where I am at does have a GTI policy but it is not pretty. They will credit you $0.051Kwh for any excess you generate, and charge you $0.132/Kwh plus monthly charges for the meter and service.

So what you end up with in most cases is paying more or about the same per month than you do now with no hope of an ROI. If you finance it you get stuck with loan payments on top of monthly utility charges. I know a lot of Texans who went with a GTI system they had to finance, and they went from paying an average $150/month to the utility, to $500 to $600/month (utility + loan payment) for the next 10 years. Those who paid cash still pay the utility about the same monthly because their rates got jacked up from 9 cents to just over 13-cents per Kwh.

Another challenge you going DIY is pulling permits and passing inspections. It is possible some DIY's can get through the gauntlet of permitting and electrical codes, but that is an exception to the rule in general. No utility will connect you, nor will any homeowner insurance carrier cover the system and your home without an approved and inspected system.

So do your homework or you might just get what you are asking for; Screwed Over.

Agree with the DIY being a very poor option. I am not in TX, but have found that getting the local utility to buy into renewable energy to be a seriously tough proposition. I've been working at it with continuous lobbying {a 1 man lobbying effort} and numerous newspaper articles through a sympathetic newspaper editor. After 3 years of trying, we have now gotten approval to do grid-tied solar, but they are dragging their collective feet in getting the paperwork pushed through.

Upton Sinclair was credited with the quote: "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!" I'd adjust that a slight bit to end, "when he believes his salary depends on not understanding it!"

Try googling solar guerilla. It makes interesting reading on the idea of civil disobedience as related to renewables.

I agree again HOWEVER In my application I plan to pay outright for the solar panels ,grid tie inverter. and racking. What can eat into your wallet after those dollars is a "chuckle head" electric contractor. Oh btw are you saying these other people actually had their kwh rate increase just because their feeding back into the grid. I understand you will get below market kwh price on feedback gen electricity.Oh ya does Louisiana , Okla, or New Mex laws force utility providers(aka Oncor) to pay different rates???

Yes that is what I am saying. As I stated before TX does not have Net Metering Laws, so electric utilities are not even required to connect you if you want a grid tied system. Many of the COOP's will not even consider it. Those that do can make any policy they want. Only exception is the city of Austin TX.

As you know TX electric is deregulated which keeps prices very low and competitive under the watchful eye of the PUC. For example you can go online and shop for electric rates. Today with say a 2-year contract you can get a rate of around $0.082/Kwh service with unlimited usage. Heck of a deal as I am locked in for 3 years. Rate sin TX have dropped 27% in the last 3 years and expected to drop even more if we get a new POTUS next year.

Likewise the utilities have policies for Grid Tied. Generally speaking the rate is much higher as opposed to standard service. Each one is unique and you have to do your own shopping. Generally speaking with respect to Solar only OnCore who owns the lines and equipment in your area can offer Grid Tied Service. The competitors like Champion are not allowed to offer the service. Only the POCO who owns the generation/transmission/distribution equipment can offer it. So they can do anything they want.

That is why I suggest you do your homework before jumping in.

Also another warning. Check with your insurance company before doing anything. Many will not cover solar systems, and the ones that will have requirements that must be met like installed by a licensed electrical contractor. So do your homework. Or you may get what you asked for, screwed over. Most insurance companies that will cover a solar system are going to require both mechanical and electrical permits/inspection with stamped documentation from a Professional Engineers to state the roof or structure can handle the load, and the electrical design is safe and compliant with all local and state codes.

I agree once again , Just curious though about solar option. TXU has been fairly cooperative since I have been in Texas although some others hate on "them". Reliant/TXU, Green Moutain, and so really bore me anyhow. When you consider alot of the US was electrified by co-operatives and not big freakin corp business. Thanks sunking

Hey Sunking
I just notice that TXU energy(my provider) is offering solar city with a 20 year lease plus fine print and monitoring svc.You can get a free quote too.

My girlfriend got a system thru Solar City last year and has been pleased with it. She has been very pleased with it. If you are interested, she will probably let you come see the installation in south Arlington, TX.

Unless you are locked into a contract with them now, I suggest you do comparison shopping,and see what other options are available if any. Can't hurt to try.

Question Sunking you post on another solar panel forum too?
Are you a certified engineer ?
