need help choosing a solar energy company

[Kennybmd]

I am thinking of getting solar electric panels for my roof. Has anyone had good or bad experiences? Any help would be appreciated. Thanks in advance.

[villagetinker]

Whatever you do make sure of the contract, there have been reports of some "zero cost" companies placing liens on homes and then when you decide to sell the new owners MUST take over the contract.
It is unfortunate, but the current utility environment in Florida appears to make it impossible to breakeven on solar, you are forced to NET metering, review the rates very carefully. DO NOT enter into any agreement with a solar supplier where they are the middleman between you and the utility.
Bottom line, there have been many threads on this in the past, and the general conclusion, you will not break even in your lifetime.
Please proceed carefully.

[Stu from NYC]

Agree with the Tinker. We looked into it and at this stage of our life made no sense.

Not to mention very expensive to remove solar panels when roof needs replacement.

[retiredguy123]

Are you trying to save money or save the planet? If you are trying to save money, you cannot do it with a solar system. A solar company will give you a totally dishonest breakeven calculation that ignores the time value of money, and the maintenance costs to own a solar system. Save your money, buy a 5 percent CD, and use the interest to pay your electric bill. If you are trying to save the planet, go for it.

Florida doesnt sell SRECs, so your break even point will be far far in the future.
In MA, our SRECs check was a nice chunk of change and our $200,000 system had an 8 year payback. (175 panels on a barn roof).
We looked into it in Florida and it wasnt a reasonable investment.

[UpNorth]

The power companies in Florida don't want you making electricity and competing with them. You are going to pay them one way or another and are unlikely to break even. Leasing would be out of the question. Florida is not a state that makes it easy to benefit from solar panels. Contrast this to CT, where I had 28 solar panels put on my roof in 2011 and have not bought a single watt from the power company since then. There is an even exchange for the wattage you produce. Every year we get a credit for the over wattage we generate. Good deal, in a state that has one of the highest electrical rates in the nation. Electrical rates in Florida are cheap by comparison.

Attaching solar panels on a sloped asphalt roof is one of the craziest ideas I have ever heard of. If solar energy was really a good idea, the power companies would have their own solar panels and mount them on the ground.

They're waiting for us all to install them and sell them our surplus electricity on the cheap

In reality, companies the World over are installing solar panels (on roofs and on the ground) but power companies have to get the most out of their current infrastructure (until that reaches end-of-life) so rarely invest in "competing" technology.

[JRcorvette]

Two things… consider the Payback time and your age. You might just find that it’s not a wise investment.
Second… I would definitely not put panels on an older roof. If you roofing is more than just a few year old it will cost you a Lot more to
Replace once the panels are on the roof.

Good Luck

Yep, many power companies will have to put large scale solar plants (among other technologies) on the ground at some point with the push to stop producing electric by coal via our feds. U seen or heard of any new coal or nuclear plants being built lately? It’s possible someday utilities will have to work with homeowners for micro grid systems (aka home based installs).

It seems that most responses focus on return on investment or saving the planet. There is another reason to consider solar, backup power during a power outage. A few years ago, we were without power for 5 days due to hurricane damage to the grid. We did not want to go through that again so we looked at backup generators and solar with battery backup. With the 30% tax credit we decided on the solar route and purchased (not leased) a Tesla system. Installation was flawless and we have not had any issues with the system.

How much did that cost, total? It would be nice to have during a power outage, but in the four years I’ve lived here, my power has been out for only a couple hours, and my electrical bill (including recharging the car) costs me about $1,200 a year. I love solar electricity, but I really don’t think it makes sense for me. I’m sure your system costs you much more per year than that.

Hard to even consider the idea when the residential solar industry is rated right up there with used car salesmen and failed politicians.

System cost varies greatly depending on house size and what you want your system to do. Our house is about 2000 square feet and after taxes the total cost was around $20K. I realize that I will not recoup the investment in my lifetime, maybe our kids will enjoy the low cost power.

Is there an ARC approved Tesla roof in TV now. It seems to be a very impressive product.

And WHY would you put holes in a perfectly good roof?! Leak central…especially with bad storms, hurricanes and hail! As a science teacher, I once used these and “replacement” windows to teach the economic futility (yes, cross-disciplines) of both.

We used Sun PPM out of Gainesvilles and were fairly pleased with their professionalism, estimates and execution. For us, we had a new roof and a sizeable tax bill for 2021 so the tax credit was crucial to making this a worthwhile endeavor although we did like the idea of the environmental concerns as well.

As many have stated, and I don’t entirely disagree - it’s certainly a toss up for long term cost savings - we paid cash for the tax credit portion and financed the rest which is basically close to the amount we would have paid for our monthly bill already. Most months we have small or no bill from Oct-May or so.

Biggest factors to consider - a) size of system vs. what you need and can export back to grid to make this financially feasible, b) age of roof for us was a factor, c) do you have a tax liability the credit will help with…. And are you paying cash or financing?

Not sure if this help - Respectfully, DB

I’ve planted many trees in my life and never stayed long enough in any of my four houses to see the trees mature to the point where they provided usable shade. Yet, I can visit places with magnificent trees that were planted by people who also didn’t see them mature.

People have built cathedrals that took generations to complete. They never got a payback for their efforts.

Nobody looks past the next quarter when running a company, anymore. It’s always short-term thinking and we are suffering for it.

We often benefit from investments like museums and parks that were made by those who proceeded us. Is that ending with the What’s in it for Me generation?

Most of these “payback” considerations fail to take into account the value that a solar panel system adds to the home. In Florida, it generally is considered to add 4% to the total value of the home. This may vary based on the age of the system and size of the home but most systems have a 25 year warranty. Since Florida only has net metering, you can only break even at the end of the year so it makes sense to size your system as close to your needs as possible. On a larger, fully electric house it can easily pay for itself in under 10 years, If you are thinking of selling in under 5 years, it probably does not make sense. It also does not make sense if you will need to replace your roof in under 10 years so it is best to install on a newer roof. You will also make the most power if you have a south facing exposure for the panels. Some quick math based on a 20kw system and a $600,000 home assuming you sell the house in 10 years.

Cost of the system: $50,000 (this includes battery back-up)
Tax Credit: $15,000
Net Cost: $35,000
Annual Power Generation: $3,500
Power Generation over 10 years $35,000 (break-even with no value add to the home)
Value add to a $600,000 home at 4%: $24,000

So if you are keeping the house for 10 years it will definitely pay for it self. If you factor the 4% value add into the equation, it can pay for itself in under 5 years. Obviously your mileage may vary but those are real numbers. Hope that helps.

[waterflower]

Get out a existing home that has panels with a EMF meter, electro magnetic frequencies.
If the power goes out in the neighborhood, consider if the power generated by the panels goes back to the grid first or to your home.
Does the panels have 100% production quality.
What is the time for the return on your investment.

I don't agree that solar panels will increase the value of your house. I think the opposite is true. Many buyers, including me, will not even buy a house with a solar system. In all of the threads on this topic, I have never seen a real estate agent provide an opinion on this. Also, I have never seen a real estate ad promoting a house that has a solar system. There is a house on my street that has a complete solar system, but it took almost 2 years to sell. Do you have any data to back up your second sentence, because I don't think many real estate agents who actually sell houses would agree with you, especially in The Villages?

Based on the MarketWatch data and my numbers, the value add would be much greater.

A few points:

1. You did not include the time value of money. The $35,000 initial cost, invested at 5 percent for 10 years would generate $17,500 in income.
2. Many people in The Villages spend less than $3,500 on electricity per year. My electricity cost is only about $1,200 per year.
3. No small contractor can possibly service a 25-year warranty. It is unrealistic. They probably won't even be in business in 25 years.
4. I don't agree that the value of the house will be increased, especially after 10 years, when the roof will soon need to be replaced, and which will require a solar contractor to remove and re-install the solar panels at a cost of about $4,000-$5,000. I don't think a homebuyer will pay an extra $24,000 for a 10-year old solar system. Most people don't want one at all.

We can agree to disagree. Some people like pools, some don’t so they add value for some and detract for others. My main point is they add value at some level, i.e. on an annual basis the home will have little or no energy bill. I agree you must be careful in choosing a vendor which is why we went with Tesla.

In reality, companies the World over are installing solar panels (on roofs and on the ground) but power companies have to get the most out of their current infrastructure (until that reaches end-of-life) so rarely invest in "competing" technology.

Those installations are typically happening in locations where regulators are mandating a specific portion of their energy production portfolio comes from energy sources labeled as green or sustainable. Ratepayers in those locations are also typically paying a premium for their electricity.

[Fastskiguy]

My parents put in a system 5 years ago from a reputable company. Bottom like, it’ll be 15 years to recoup their investment and the company is out of business. Home insurance is requiring a new roof as the home is in pinellas and is 10 years old. Electricity is ridiculously cheap here so solar is a tough sell. On the other hand, if the power goes out they’ll be fine and they love the air of superiority when arguing with the greens about energy.

The reason those states have a high kWh charge is because the ratepayers are subsidizing the solar.

I suspect before solar panels are paid off a better and more efficient way of generating electricity will be available

[Robnlaura]

Tesla always provide a great quote. They are thousands cheaper than these scumbag solar companies.. I’d use them to get a good idea of what you should be paying and don’t do this lease junk they have come up with. As far as I’m concerned I’ll wait it’s a major scam at the moment.

[biker1]

Who is your power company? If it is SECO, then you will probably have a minimum power bill of $420 per year. There is a daily connect charge.

Based on cost of electricity in our all electric home think it would take many many years to even break even with solar. Not a wise investment.

[biker1]

Yes, I agree. I was only pointing out that you probably can’t drive your electric bill to zero with solar panels because of the daily connect charge. It is actually a pretty good percentage of our electric bill.

I've had solar for 20 years on my 3000 sq ft home with a 5 ton AC unut. My power bill has always been less than $70.00 The older panels wore out. Thery were the fist ones on market. The new ones I'm having installed product 3 to 4 times the wattage. and, so having the newer ones should last me the rest of my life. They are 92 % effient for 25 years. I'm paying cash for mine of the amount of approx.25k, but then I get a 30% tax reduction good for 5 years. My system is approx. 10kw and one of of the best panels made ( Enphase). The power rates are ridiculous increasing ever year. My retirement income is doing the opposite. I'm a retired electronic enginner and was trained years ago on solar. So I say, if you are 70 or less GO FOR IT. Above that age. ? ?

My bill is about $170/month. You are saving $100/month - at $25,000; that’s a 21 year payback.

I just don’t think any system will last 20 years. Your roof doesn’t last 20 years.

Why are you generating $3,500 per year in electrical power, when your second link says that the average monthly electric bill in Florida is $128, which is only $1,536 per year? Your initial investment of $35,000, if applied to paying for your electric bill, would be enough money to pay for your entire electricity usage for 23 years, or longer if the money was invested with interest. How can you justify an initial investment of $35,000?

Wow. It's probably something simple that a roofer could repair in 10 minutes, but the roofer won't touch the solar panels. Does the solar system warranty say anything about roof leaks? If the solar contractor doesn't fix it, you may need to file a homeowner's insurance claim. A leak like that can cause an expensive mold situation. Good luck.

[Lottoguy]

Remember those panels will have to come down when you replace the roof. Not sure what the added expense will be but you should look into that.

In guess you will need to tell your insurance company about the solar panels, no idea of the impact, but I would do this first so that I am not surprised.

How long do you think your roof would last if you put a cover over it? Like, solar panels?
In my opinion, the solar panels will shorten the life of the roof because of more dirt accumulation under and around the panels. The panels do not cover the entire roof anyway. And, what do you do when you have a roof leak? (see Post No. 49). I doubt that a solar company will be very responsive when you have a roof leak, and I do not think a roofer will be interested in removing solar panels to repair a leak. A roofer can usually repair a simple leak by replacing a few shingles, but if the leaking area is covered by solar panels, it presents a whole different problem.

I've had solar for 20 years on my 3000 sq ft home with a 5 ton AC unut. My power bill has always been less than $70.00 The older panels wore out. Thery were the fist ones on market. The new ones I'm having installed product 3 to 4 times the wattage. and, so having the newer ones should last me the rest of my life. They are 92 % effient for 25 years. I'm paying cash for mine of the amount of approx.25k, but then I get a 30% tax reduction good for 5 years. My system is approx. 10kw and one of of the best panels made ( Enphase). The power rates are ridiculous increasing ever year. My retirement income is doing the opposite. I'm a retired electronic enginner and was trained years ago on solar. So I say, if you are 70 or less GO FOR IT. Above that age. ? ?

As a retired engineer, you should know that Enphase does not make panels, they make micro-inverters.

I've taken my 2012 solar investment and added batteries in 2022 ish. Can now run through the night of an outage and keep the food from spoiling. No generator, just hybrid inverter.

Been hearing that some h/o insurance companies are canceling coverage completely for folks with panels on house. I have metal roof and no insurance coverage on panels.

After ten years I can attest to this fact: Solar panel drippings cause corrosion on otherwise perfect metal roof. I have the Galvalume sheets. Only place with rust is along the drip edge of the aluminum framed panels. If a contractor had told me back at install to paint that drip area, this could all have been avoided.

Daily connect charge is for the 'grid as your battery'. You push into grid in the daytime and pull back at night. Cheap battery at about $1 a day. Real batteries can run over $10k.

You have a classic problem of Aluminum in contact with steel, these 2 metals do not play nice together. I doubt that any amount of paint would have stopped the problem. I always try to use stainless steel hardware if it is going to be in contact with aluminum. I would suggest try calling Eastwood (yes automotive products) and see if any of their excellent rust preventative solutions will help with your situation.
Hope this helps.

I did that Ospho treatment, twice, sanded and painted with that Elastomeric white paint. Two coats and seem 95% better.

Attaching solar panels on a sloped asphalt roof is one of the craziest ideas I have ever heard of. If solar energy was really a good idea, the power companies would have their own solar panels and mount them on the ground.

As many of the US energy companies do. Example:

Solar Energy - Duke Energy (https://www.duke-energy.com/energy-education/how-energy-works/solar)

Those installations are typically happening in locations where regulators are mandating a specific portion of their energy production portfolio comes from energy sources labeled as green or sustainable. Ratepayers in those locations are also typically paying a premium for their electricity.

FACT CHECK: True,

when solar first started, NYPSC mandated that Niagara Mohawk, which had the lowest cost of electric generation in the Northeast, accept power from solar generation. The cost to upgrade the mechanical systems to electronic systems to accept the irregular flow from solar, was not yet accepted into the rate base for the mandated return, and the company went bankrupt. . .

So be careful what you wish for.

Weather based electrical generation is inherently unstable as weather is inherently random and unstable. The solar based infrastructure requires electronic switching devices to manage the instability (think passing clouds) along with the steady legacy generation. Electricity can't be easily stored on very large scales. . .

The UK found out one day when the sky was overcast and the wind didn't blow at all anywhere. . they had to fire up back up coal plants at a very large incremental cost to maintain adequate power supplies to the grid. It might be sustainable, but instability might be more expensive than legacy stable, such as nuclear power.

your small implementation is not the same as at massive scale. . . scaling can be exponentially more difficult and expensive. .

Still scratching my head why we are not generating more electricity from nuclear power

[biker1]

Three unfortunate events had a profound impact on public opinion, a history of cost overruns hasn't helped, and lingering, perhaps unwarranted, concerns about nuclear waste storage has also been problematic. We are, fortunately, starting to see some progress in Georgia.
