When Considering Green Initiatives, Many People Think Of Solar Panels.   The Sunnier The Local Climate Is, The More Savings Is Achievable. 

 

There Is Justifiably A Lot Of Excitement Over The Savings Created

By A Solar Panel System. Below Are Some Addition Considerations.

When Considering Energy-Saving Home Upgrades, You Should Taking Into Consideration:

  • Will The Upgrade pay for itself with energy savings during the period of time you expect to live in the home?
  • At The End Of Year-8 A Solar System Typically Will Have Paid For Itself in DFW.  We provide the details below.
  • Will the Upgrade increase the home’s resale value?
  • It May. Appraisal Standards for Solar System Equipped Homes are not standardized.  It may depend on the the Buyer’s Mortgage Company’s Appraisal Guidelines. We provide details below.

Adding Attic Insulation Is #1 Item For Increased Resale Value

** The #1 Home Improvement / Upgrade is adding attic insulation (to at least R-38 in TX).   This home improvement came at the top of home improvements cost versus increase in home value at 117% of the cost of the insulation project.

*4  If your Federal Income Tax due is less than the Solar-System Tax Credit the year it’s installed, the remaining tax credit will be applied to future Federal Tax bills until the credit is used.

Can You Sell Excess Electricity From Your Solar System To ONCOR?

Yes, IF you sign with a Retail Electricity Provider that offers this.  These Retail Electricity Providers have solar-buyback programs.  Once signed with one of them, Oncor reprograms your existing smart-meter to meter both the electricity flowing into your home and excess electricity (more that you are using) flowing outward from the home into the Power Grid.  Once reprogrammed, your Meter becomes a Dual-Register Meter.

  • Reliant
  • TXU
  • Reliant
  • MP2 Energy
  • Green Mountain.
  • Each Retail Provider has their own rules.

Reliant offers the simplest plan.  Their “Simple Solar Sell Back Plan” gives you a credit (against future electricity billing) at the retail electricity price.  In addition, you get a 12-month price discount for electricity consumed from the power grid.  The other 3 retailers have more complicated programs, check their websites to see details.

Solar Panel System Cost, Annual Savings, Lifespan,

 And The Number Of Years To Pay For Itself 

  •  A 6 Kilowatts Solar Panels System in DFW (installed) Net Cost = $9,025.  After Income-Tax Rebate & ONCOR Rebate are subtracted from purchase cost.
  • For a home in suburban Dallas, the calculator determined: Annual Electricity Production for a 6 killoWatt system = 9,400 kWh (in year #1).*6
  • The average price per kWh in DFW = 12.5 cents.
  • We provide a 30-Year Chart below showing savings.

How Long For A Rooftoop Solar System To Pay For Itself In DFW?

Click Here To Scroll Down For Warranty Period For Various Brands Of Solar Panels: Solar Panel Warranties By Brand

Materials Warranty: Panasonic & Sun Power Are The Two Brands With 25-Year Warranty. 

Performance Guarantee:  Most Panels Will Produce At Least 80% Of Their (when new) Power-Output Rating At The End Of 25-years.

  • Using the best warranty, we conclude the decrease in electricity production to decrease by just under 0.8% (8/10th of 1%) per year.
  • Our number is rounded up to 0.8% which shows year 25 to be at 77.5% in the chart below.  We accept the 2.5% error in Year 25 in order to simply the math.
  • $9,400 kWh X 12.5 cents / kWh = $1,175.00 Savings In Year #1.  
  • After year   8 –the Solar System Has Paid For Itself.
  • After year 17 — the Solar System has paid for itself TWICE.
  • After year 27 — the Solar System has paid for itself 3 TIMES.
  • Over the 25-Year Warranty Period =  $23,500. Total Savings.
  • In Year-25, The Solar System is guaranteed to be producing 80% of its (when new) production.
  • The Solar System Is Not Worn Out After 25 Years.  It continues to generate electricity at around 80% of its original (when new) capacity in year 25 and the production lowers about .08 (8/10ths of 1%) each year.

Additional Solar System Costs To Consider

  • How Long Do You Expect To Be In The Home?  When you sell, you pass all future savings to the new owner.
  • If your roof needs replaced, the Solar Panels must be removed & reinstalled at your expense.  Expect to pay $3,000 for the remove & replace service.
  • You must consult with your Home Owner’s Insurance for details on Solar System Coverage.
  • You may need to increase your Home Owner’s Insurance Coverage for the value of the Solar System.  Your premium will increase slightly for the higher coverage.
  • If your roof is damaged by hail, Insurance Companies pay to replace the roof, but some may not pay to remove & reinstall the Solar System.  You need to check.
  • Hail is not likely to damage Solar Panels, but a house fire will.

The Resale Value Of A Solar System Equipped Home  

  • “One of the biggest problems appraising the resale value of a rooftop solar installation is there’s not enough standardized information. Solar PV may add value but that is not a given across the board.” says Sandy Adomatis, SRA, LEED Green Associate and Owner of  Adomatis Appraisal Service.
  • Adomatis was a co-author of “Appraising Into The Sun” a report issued by the Lawrence Berkeley National Laboratory in 2015. It’s one of the most detailed reports on how to evaluate the value of rooftop solar to real estate value. But it’s limited to just 6 states (Texas was not included).
  • $3.76 per watt: The average value of new rooftop solar to a house in California in 2016.   A new 6 kiloWatt System value (on a resale home) = $22,500
  • $1.90 per watt: The average vale of a 12-year old system sold in 2016 in CA.  A 12-Year Old 6 kiloWatt System resale value = $11,500.
  • The 2018 median home value in CA = $544,900.
  • The 2018 median home value in Texas = $188,700.
  • With a CA median value of nearly 3 times that of TX, it’s likely a CA solar equipped home’s additional value would be higher than in TX.
  • Nearly all Mortgage Lenders require Appraisers to use the Sales-Comparison Approach.
  • The appraisal is based on 3 similar, nearby homes that sold within last 6 months.
  • If a home with a Solar System is being appraised, if 1 of the 3 compared homes did not have a Solar System, some Lenders may assign $0 value.  This appears to be changing with the passage of time.
  • FHA requires the Solar System’s value (owned, not leased) be assessed and must be added to the appraisal value of the home.
  • Fannie Mae (conventional) mortgages indicate the value of a solar energy system (owned, not leased) may be included in the appraisal value of the home.
  • Freddie Mac (conventional) mortgage appraisal guidelines were changed as of March 7. 2017.
  • They state “Updated appraisal requirements for the valuation of properties with (owned, not leased) energy features & high-performing, energy-efficient properties.”

Should You Install A Solar System On A Home In DFW?

There is no definitive answer to “Will I be better off with or without a Solar System on my home?”

  • You will be better off with a Solar System provided if you will live in the home for 8 years after installing the system — as the savings will have paid for the system.
  • You will likely at least break even (with higher resale value) if you sell the home in less than 8 years.   We discussed the potential issues above.
  • It’s important to note that a Mortgage Lender may have guidelines that don’t align with Fannie Mae & Freddie Mac (conventional) mortgage guidelines.  Right now it appears the language says “The Value Of The Solar System may be added to the total appraised value of the home.”
  • For FHA Mortgages, right now it appears the language is “The Value Of The Solar System must be added to the total appraised value of the home.”

We also provided the additional hidden expenses a Solar System can create, such as removing & reinstalling to replace the roof.  In an area where hail often damages roofs, you need to know the details of you Home Onwers Insurance regarding if they pay to remove & reinstall the Solar System if the roof must be replaced due to hail damage.

NationWide Home Insurance says: “Rooftop Solar System insurance coverage is included in most homeowners insurance policies.  Solar Systems are largely considered a permanent attachment to your property.   You may need to increase the amount of coverage on your home to account for the cost of the Solar System, which will raise your premium. It’s important to note that some policies may exclude damage to these attachments when it’s caused by a particular threat such as wind.”
