I just read again in a few different places that if you face your solar panels west instead of south they'll produce 15% less electricity. BUT, if you have Time of Use (TOU) electric billing with high peak rates, you may benefit from having your panels point south (or southwest). It all depends on if you want to generate the most power possible or not. If you do, then you keep them facing south. But if you have TOU billing and want to generate the most energy possible WHEN THE POWER COMPANIES CHARGE MORE FOR IT (peak rates) point them south. Or southwest. And they also pointed out that the angle of the solar panels is much more important than the direction. You want the sun to hit perpendicular to the panels. That may mean they need to sit at a 45 degree angle, but maybe your roof is only at a 30 degree angle. If so, you need to prop them up. And speaking of direction, whatever direction you choose, it should be based on geographical direction, NOT magnetic direction. A lot of people won't even think about that.

50% reduction in price?  Back when you set yours up GEL was the best setup.  For the same price I like the LiFePO4 today. 

Home and business may be different.  I've some friends who generate electricity from surplus natural gas back to electric companies in 4 or 5 states and they get a check for it. 

Maybe if you are just looking to cover a shortfall in the afternoon and you don't have storage pointing to the west would help.  With storage that won't help me at all...the storage is the key.

Using Renogy as a benchmark there's about a 50% reduction in the last 18months.

Still since I don't deep cycle and it's pretty stationary setup, $180/ea for 12V 100Ah GEL was my best choice.

I think a law back going to the Jimmy Carter debacle requires power companies buy your surplus electricity; if you want to sell some back. 

Nope, there are no buy backs in GA.  Or I should say no new buy back programs.   We have about 14 electrical utilities in GA and the only thing they allow you to do connect to the grid and offset your cost by what you generate AND consume. You don't get paid for the excess.  The rest is a freebee.  GA Power (the only non co-op) did offer a buy back for the first 5,000 applicants.  That deal got snatched up in the first week about 4 years ago.

.....about putting solar panels on the west side of the roof instead of the south side.

I think I've seen some solar farms that favor the west side.  Especially, I'd think, if you're going directly to grid, then power in the afternoon would be more important.
The one farm I'm thinking of has the panels running E-W, tilted towards the west.  Trying to find a sat picture, but doesn't look like they've updated that section since the farm was installed.

Good news.  For once.

Now, what is the other shoe to drop?

Reloading / Re: Primer Counter - PLC Arduino
« Last post by alfsauve on May 09, 2024, 10:50:21 AM »
I decided at the start of the new year to clean up some projects.   The Primer Counter had a little quirk in the s/w I wanted to fix and in general just clean up the code.  Make it neater.   Over the last year or so I had added a 2 line LCD display with an RGB backlight.  The LCD never had great contrast and I finally figure out that because I was powering the Nano board through the USB port, then it was regulating that 5V so that what was available to the outboard display was 4.5V.  Turns out the Grove LCD likes a full 5V.  Now it's very bright and clear.  I also decided to replace the circuit board with a commercial one to make things even neater.

Below are the pictures of the old board and the new one.  I did elect to put the resistors for the LEDs onboard and instead of using USB power wart, I got a full 5V power supply feeding directly into the board.

I think a law back going to the Jimmy Carter debacle requires power companies buy your surplus electricity; if you want to sell some back.  That ability comes with caveats like transfer switches, etc. to protect lineman from have charged power lines from homes and businesses when working on the lines and the electric company must be notified of your intentions before you can tie into the system.

Next if your panels are fixed it's all about getting the most photons to hit the panels...and that's the middle of the day.  Pointing westward with fixed panels won't do the trick...someone's good idea...a government worker no doubt?  Pointing east or west is 25-30% less power capture.  And if they were thinking that is because of the cost of electricity....then you batteries are way too small because you should easily charge them up facing south and cover that westward high cost power time.   

In addition, after a little study I'm going to be putting 4 of my 100 watt solar panels into series to bulk them up to 48 volts from 12 volts.  So I'll have 4 in a "unit" then connect the units in parallel to feed 48 volts to the charger.  Those 4 panels will be capable of generating an open voltage of 97 volts...and I have a 250 volt rated charger.  So I can loose 2 units and still be covered.  48 volts means smaller wires and easier to install...and cheaper..but the higher open voltage rating pushes up the cost of the charger.

I have a 60 amp charger (Victron MPPT MC4 250V 60..$402 delivered).  Therefore, 12 volts limits me to 720 total watts worth of panels whereas 48 volts allows 2,880 watts worth of panels.  So, in my scenario I can have 7 units of 4 panels each generating 2,800 watts maximum.  I'll run 6 solar "units" and 2,400 watts for longevity to not stress the system.  Maybe leave a space to add that final unit as panel efficiency falls off over time.  And I just bought 2 more panels for $58 and a nickel each....and made in Thailand NOT China.

Looks like wait tines for online transactions are now happening  in about a week.  I have been thinking about buying a new can.  I will test this and find out.
