Wholesale of Retail Net metering?

I'm going to assume when you ask which "system" is better you mean which will be the most cost effective for you in the long run.

Without knowing much about the bigger picture particulars with TX POCOs and also knowing little about your particular situation with regard to use patterns and plans, it's not possible for me to offer more than a wild guess as to which way to go.
You ask a question that needs a lot more information before an informed opinion can be offered and so it's a big question.

But I'd offer a general statement that it's usually good to start with an analysis of the situation taking long term goals into account including an energy budget to meet those goals. Then, see what tools/assets are available to meet those goals, often a mix of energy sources including conservation efforts, and then determine which mix of those tools/assets are the best match with your priorities and goals including ease of use, cost effectiveness other priorities that best fits the goals you set keeping in mind that PV is only one of several tools that are available to meet whatever your goals might be.

Beyond that, if I was in TX and had convinced myself PV was the best choice to meet my goals, I might first look at not oversizing the system and then look at what you call the retail plan with no rollover and know that there is no perfect way to predict the future. I base that SWAG on the idea that retail will probably be more $$'s to me than wholesale, and a not oversized system will cost less than an oversized system. I'd then be able to meet my goals with as little commitment of funds on a system and optimize the overall cost effectiveness by getting retail for what I do generate.
But, again, all that thining is predicated on the limited information I've got to witk with so take it for what it's worth.

Also, as part of my design and meeting goals, I'd also look at all the other plans that don't offer net metering. There may be one or more that offer prices and features that may make more long term $$ sense.
In spite of what you may hear or read, PV is not necessarily the most cost effective way to meet a long term electricity need.

Take what you want of the above. Scrap the rest.

That is point, see if a rate with no metering is best, and don't worry about surplus power, to which a smaller system would be better (that is, less chance of generating more than needed, getting no return despite on extra)

You might take a look at the following site if you have not already:


Pulse power has the month to month rollover credits in addition to buying back the power at retail rates. This is the one I’m looking at possibly going with once my solar is up in active. I still have to verify their solar plan retail rates.

in Texas you have to watch out for every kilowatt hr you use Ercot/encore will charge a transmission rate of ~$0.05 per kWh. So even if the electric company buys back your excess power at retail and you generate more than you use, you will still owe a small bill every month in a transmission charge.


The other thing I have seen with some of these power companies is that their solar plan retail rate is higher than a non-solar retail rate then they just buy it back at wholesale from you.

Thanks for the info!

Yes, I do see the pricing shenanigans too, and of course the transmission fee.
Other tactic is to be close to even, and not worry about rates or rollovers.

How far you on your install? I am on hold as I resolve my roof issue.

Late into planning. Getting ready to apply to Encore for to start the permitting process/interconnect agreement

Not the OP, but how would you plan based on the fact that these plans will change probably long before there's an ROI on most installs? Does it make more sense to then just continue with a regular meter and bill and let others adding to the grid help absorb any future cost increases?

Looking at market future prediction, 1/3 of Texas generation is from Nat Gas, and that is expected to increase in price, adding to the expected increase for electric generation.
There is no prediction where price of Texas electricity will NOT rise, just a Q on how much/how fast.

Yes, but the question is if adding the extra expense of a PV system will be higher at some point after others have already added capacity and brought a regular metered price down in relation to a PV system cost.

Valid concern, but demand for electricity will only go up. I see more and more houses add external lights, pools, and other enhancements.
And then there is EV.

My plan is to switch from Gas to Electricity. Water heater done, range done, heating using portables (rarely so cold need heater), our only big item is cloths dryer.
Have an 8.1 kW solar.
I estimate I will save about $2850 off annual utility bills

BEV is on short list, saving gas money too.

So no matter which way my electric (and gas) bill will go, I will be well ahead.

Actually $0.08 a kW is not bad considering my 180 MW solar farm sells electric on some days as low as $20.00 A MW which comes to $0.02 a kW. Granted we have a real time market price that swings all over the place during a given day. At times I have been able to sell power at over $300.00 a MW and up north in Michigan and Minnesota I have seen price spikes as high as $5000.00 per MW and lows at -$150.00, yes you read that right they actually charge producers to put power onto the grid cause demand is that low at that time.

As a residence owner the best thing you can do is probably the roll over credits and size your system to average 0 kW or a slight positive every year. Even at $0.10 per kW you would have to produce an extra 50 kW a day to have it actually be a meaningful amount by the end of the month and get maybe $150.00 back minus connection fees and other fees. For the additional cost of installing that much solar it will drastically increase your payback. Also most residential meters are only rated to handle 225 Amps of flow in either direction meaning a 25 kW system will load the meter to its maximum. Now I have a 400 Amp meter that I had to pay for a lot more expensive service entrance equipment to support, but it feeds two separate 225 Amp boxes in different buildings. I could install about 45 kW of solar on that, but it would have to be divided and tied into each of the individual service panels.

For me it is more of a hobby, so I plan to install a small system under 5 kW and see how it affects my electric bill. Then I can slowly expand on the system to hopefully eventually eliminate my electric bill one day. Now while I am doing that I will also work on other things to reduce the bill such as changing out lighting and using supplemental or more energy efficient technologies to heat and cool the buildings. A 5 kW system should be easy enough to install on my own with minimal help and cheap enough that I don't have to go into debt to do it.
