I debated posting a response but the amount of misinformation made my brain hurt so here goes
Lots of things to consider when deciding whether PV solar is right for your situation, I recommend you do that research on PV solar forums not pool forums
.
100%
Most solar systems are in excess of $20K. The ROI is in excess of 25 year
This is very area dependant. We were early adopters (so we paid about double after 50% rebate and tax credits what a comparable system would cost today) and installed our pv system in 2005. Our savings hit equal to install cost between year 11-12. Today in CA due to the shift to net metering 3, it is estimated at about the same 12yrs due to the almost requirement to install a battery storage sysrem
You can have equipment fail, damage from a storm
Anything electrical can fail but this doesn't stop it's install. Because of the capital outlay for pv solar the electronics and panels are warrantied a min of 10yrs. Storm damage is typically covered by homeowners insurance just like most other storm damage subject to your deductible.
In our case at year 16 we had to replace 1 inverter at a cost of ~1700. It could have been done for ~1200 but I opted to install a larger inverter so as to support additional production from several panel replacements (our panels are 167 watt, while a modern panel of the same size will produce 400 watts) utilizing the same racking.
This is true for a roof mount system which is why a legitimate solar contractor will not install on a roof with less than 20yrs of remaining economic life. In additional they will warranty any penetrations for a minimum of 10yrs. If you have the room, this is completely mitigated by a ground mount system. Our system was ground mounted due to the shape/pitch/orientation of our roof. At install the ground mount racking added less than 10% to our system cost.
And having solar will not increase your resale value
The appraisal standards of fhfa who set guidelines for fnma, fhlmc, fha and va all assign a value to Owned solar panels of ~10,000 in home value for every ~$1000 in expected annual power production
Panels lose 10-20% of their effectiveness in the first two years of use
All tier 1 panel manufacturers warranty a degradation rate of no more than 10% over the first 10yrs . Solar panels typically experience a gradual decline in power output, with an average annual loss of around 0.5% to 0.8% per year
If you need your roof replaced, you'll have to pay to have the solar panels removed, and then pay to have them replaced. Some roofers will offer this service at a fee, but many won't.
This is true
The power has to be fed into your power company's grid - it doesn't go directly to your home. You sell power to them, then buy it back to use it.
You use the power your panels produce as it is being produced- any excess production is fed back into the grid and effectively sold to the power company to be sold back to you in the evening when the panels are no longer producing. This too can be mitigated by the installation of a power wall which had fallen significantly in price over the years.
There is usually a fee to belong to a co-op power company. In my case it's about $30/month or $1/day.
This is true and very area specific. There is generally a min monthly fee to be connected to the grid which must be considered in your roi calculation.
