I have been asked this question way too many times: Does solar power really pay off? Especially my neighbors, they still ask if my investment and work on my solar power system pays off.

The simple answer is a resounding YES!

I have invested a lot of time and money into solar, and I have made many really expensive mistakes as well. But what I have learned along the way was priceless. And this forum proves that everyday. This forum has been the one source I can rely on for straight forward information. Of course YouTube and many many other sources have been key in my education on solar power, but this forum is great, Thanks Will!

This past winter, and even in the recent weeks/days, our solar power has been relentlessly powering on day and night without a hiccup providing us with heat, light and power to the most common of needs. We had power outages over the past four months that are surely a sign of things to come. Just in the last three days, we lost power twice for several hours each time in the middle of the night. My wife and I didn't even know it until morning, when the power was back on. How did we know? Some WiFi lights in our house turn on when power is restored, and some clocks are blinking as well. Our off-grid systems only powers the most critical components. We have ran electric to several rooms like our kitchen, living room, bedroom, utility room and garage. It keeps our furnace, sump pumps, fridges and freezer and much more running with everything we need, and do not go without.

Now to the question, is it worth it. My neighbors get up when there is a power outage, and see that our outside security lighting is still on, also they can see that our furnace is still running by the steam coming from our furnace exhaust on the side of the house. Now they are all interested in how this works. The interest has really peaked. Everyday I am hit with questions, how much does it cost, is it hard to install, can anyone do it, do I need a company, and the biggest, can you help me if I want one like yours? Even my nosey neighbor who caused me BIG problems when I started this project who reported me to the local code enforcement office, and payed me a visit. They want to know how this all works. Naturally, I will tell them to get lots of AA, AAA, D and C size batteries, as well as a fireplace.

My wife and I have lowered our power bill by 65%, and always have power when others don't. In wide spread outages, my family members living close, pick up and move to our house when it is cold to camp out till the power comes back on. Free heat, light, warm showers and hot food at our house. We even installed a roof antenna to pick up 30+ channels if cable is down. So we have local news and entertainment for all.

So, I ask you, if you ever question if your solar investment was worth it, what do you think now?

Just ask them what their ROI is for that $82K truck they got sitting in the driveway with a $1300/mo payment. Or that $30K Razor. Or that $100K RV. Or that airplane sitting in the hangar at the airport. Debt free at 38, off-grid at 51. Love it.

I hafta chuckle. I'm quite a ways up north, I built my house on a 1700' Ridge above 3 joining valleys and while quite rural there are homes & farms "below". Big Power wanted $55,000 to put in poles, cut an accessway through my forest and more.. You can figure out what I told them to do with that quote (especially considering it went up by $11,000 from the previous quote before they got their "increases").

Installed my system with Heavy Lead back in the day (2015 "Lithium" anything was beyond ludicrous and then some). As expected, cared for but abused, so they suffered, then I made the move to 30kWh of Lithium Iron Phosphate and there is no looking back now... The numbers say I make back the investment by December of this year, all-in.

The "Chuckle": 7 Years ago, you saw a few panels here & there and some farms with ground mounts etc but not very much at all... After I got setup, I have all the power I need (now with 5 days reserve) and so being rural, the inevitably Power Outages hit (typically 15 to 20 times per year) and guess what, everyone saw "The Lights ON on top of the ridge" and of course the Curious furtled up the backroad to see a rack of panels.

Now, pretty much every house has panels, farms have also started to install on barn roofs, ground mounts and more... There are even a couple of Dairy Farms with Solar, Wind, Biogas that are no longer consuming grid power , just pushing excess to grid. Ask any "Dairy Farmer (200+ head)" what they spend on energy in 12 months, WARNING, be seated when they answer !
 
Total electric and my bill is $23 a month (meter/grid service fee). We do have considerable heating and cooling demand. Our bill was in the $120-$150 per month when we installed solar in 2019. Self installed for about $14k with a ROI of just over 7 years. Planning to retire next year with a big small regarding my power bill.
 
So far, I've built a 13kw PV array with a 81kwh battery bank and generate 18,000kwh/year with 15,000kwh actual consumption as an off-grid system.

Power Company = 11c/kwh which means I save $1,650/year (15,000kwh * 11c) + another $100 on hot water. It's been 11c/kwh for 4 years now - prices are bound to go up at some point with all the green new deal and carbon tax 'stuff' going on in my state.

However, including US tax credits, my current ROI = 23.54years

I don't do this to make money, I do it to be able to be 'Off Grid In The City' - e.g. a prepper motivation and because its a fun hobby (it's soo cool to pick real power out of the air). :)

Is that 0.11 Cents per kWh "Plus" delivery/line/service fees on top ? That also adds to the ROI Equation. Up here, that easily adds 1/3 more $ on top. Some areas also tax power then tax delivery etc differently adding even more hump to carry.

It's 0.11c/kwh 'overall' - e.g. $Paid / kwh consumed. It varies from 0.1084/kwh low to 0.1145kwh/ hi depending on my use / fees / tiers of use. Here's an example bill of 'hi use'. $330.80 / 2,934kwh = 0.11275/kwh. This is Pacific Power in Oregon, USA.

Yeah, my "ROI" would be about a 48 hour power outage in the middle of summer or winter.
Thats what mine is. I've avoided 3 power outages that lasted between an hr and about 8 hrs already in the year mine has been up and running. On top of that I have been saveing about $100/mo so my payback is about 6 years as expected (after the tax credits)

Ouch ! "Oivey" doesn't quite cover it... what a pile of tack-ons.
 
knock on wood we have not had outages of any length here. But my stress is down SIGNIFICANTLY knowing we are good to go for a long outage. I don't know how much we have lowered our e-bill since some items are always on the solar setup. Others would be attached for long power outages.
 
You all make it clear that solar is worth it. From the cost perspective to power independence and everything in between. How we have benefited is immeasurable. One of the aspects I have not mentioned is the value of our home. If for any reason we would decide to sell, and wanted to leave the solar in place would add significant value to our property.

For all the reasons, learning about power independence, and the value of that knowledge is also a benefit that very few people have. At least around here. With the threat of external entities possibly targeting our grid gives me added piece of mind.

No matter how you look at it, I think solar really pays off. Thank you to everyone who contribute to this forum. You have all helped me.
 
Most especially when it is -30 or 100 degrees out. You really develop an appreciation for the little things like Power.
Amazing what people did 5-10-15-20 let alone 100 years ago ?

As for our monthly utility bill, usage is so low installing a system isn’t reasonable until our roof needs replacing in 5-10 years.

Now our off grid cabin, it’d be 30-50k to run 10-15 poles for a service drop. For a seasonal weekend cabin, we’ll deal with a modest system (800w PV & 2-4kwhr storage) for lights and we’ll be good.

That bill in Ca would have been terrible. I used 253 kwh in feb and my bill was $73.

I have been running my house on my 24v RV battery and inverter. was just the heater full time but I built a second battery and the house runs full time right now on 2 280 ah 24v setups and 6 405 w panels. I'm waiting for my inverters and I have 24 panels and 30 kwh of batteries. Can't wait to be grib free. I'm in the city also
 
Good topic but could we get specific details please.

Spreadsheet data detailing a complete listing of the hardware used, the cost of each item, tools/materials purchased, time spent installing and/or price paid to have it installed, rebates actually obtained, etc. Data like this would immensely helpful to create a fact based solar power system cost/benefit analysis.

Also include your objective/goal for implementing solar (save money, reducing carbon footprint by some quantified amount, remote location so no option to grid tie, etc.). A brief reason for implementing your solar/battery system instead of other alternatives like a generator/battery system, wind/solar/battery system, hydro/battery, etc hybrid systems. Lastly, for those who have actually implemented a working system that has been in operation for at least a few year (aka you stuck with it) was it worth it? How did the maintenance go regarding money and time wise? Suggestions/recommendation on doing it all over again? Was the Return On Investment (ROI) real or fantasy?

Information like this is what is needed so that someone who is thinking about implementing a solar system, or any power system for that matter, can make an informed factual decision.

Especially guys Like Richard Perez who started Home power 30 years ago.

Him and his wife Karen really lived it.
 
So, I ask you, if you ever question if your solar investment was worth it, what do you think now?
Probably not, I can't ever see the batteries paying for themselves in my lifetime (not long left).
About 80% of my house is solar powered.
Nice not to have power loss when the grid goes off though.

My grid power costs 12c/unit + $1/month utility company fee.
Before solar $50/month, after solar under $10/month.
But I was always planning for TEOTWAWKI, so money wasn't my major concern.
