Solar FAQ

1)  Why should I invest in a Solar PV System now?


  • Eliminate your net electric bill, use current incentives. Solar Energy Supply's high-performance solar photovoltaic (PV) systems combined with state rebates, federal tax credits, depreciation and Louisiana's Net Metering program, create very favorable financial incentives for installing a solar system now.
  • Declare energy independence.  Invest in a Solar PV system and generate your own electricity from sunlight - a clean, silent, renewable energy source with no emissions.
  • Enjoy long-term solar life expectancy with PV panels' 25-year warranty and 40+ year lifespan.  Your solar system will last for years to come, sheltering you from rising electricity rates.
  • Add value to any property.  Solar systems are exempt from property taxes, but the value of a solar system is added to the appraised value of a property.  It's one of the few home improvements that can be justified in terms of return on invested dollar.

2)  How does a Solar PV System work?

PV Solar Systems consist of modular panels made of silicon, which react directly to sunlight by generating electric current.  An inverter changes the DC (direct current) generated by the panels into AC (alternating current), supplying power for lights and electrical appliances.



3)  What size system do I need?

Solar Energy Supply tailors PV systems to the unique energy needs of each customer.   A detailed site and energy needs analysis is necessary to determine appropriate system size.


4)  Do I need a battery backup?

No.  Solar Energy Supply's PV systems connect to the local utility grid.  No batteries are necessary.  On sunny days, the solar system sends surplus energy to the grid for credit on your utility bill.  The utility provides power at night and on rainy days, and you tap into the credit your solar system earned on sunny days.


5)  How much does a PV system cost?

System cost depends on size, materials and labor.  Most Solar Energy Systems pay for themselves within 4 to 5 years.

Keep in mind that each PV system is sized to the unique annual energy needs of each customer.  Systems aren't sized for square footage, but designed to replace the total amount of electricity you use annually.  Site specific elements, differing electric rate schedules, and financial incentives that you may or may not qualify for all affect
your total system investment.

Please contact a Solar Energy Supply Systems Energy Consultant for an energy use and site analysis survey and a detailed explanation of system costs.


6)  Are there rebates or financial incentives?


  • The Federal Investment Tax Credit for solar systems is 30% of the system's installed cost.

  • The Internal Revenue Code has a 5-Year Accelerated Depreciation Schedule for commercial solar systems.
  • Solar systems are exempt from Louisiana's property taxes, (please talk to your C.P.A. about your tax situation) but the value of a solar system adds to the appraised value of a property.

7)  Is financing available?

Yes.  Please discuss financing options with one of Solar Energy Supply's Energy consultants.


8)  How much will I save on my electric bill?

Optimally, your Solar Energy Supply solar system will be designed to eliminate your electric bill.  However, restrictions on space, budget or sunlight exposure may affect the size of system that can be installed.


9)  Does my house have to face south?

No.  South-facing systems are ideal, but southeast or south-southwest can be used with minimal loss of procuction.


10) Is a PV System Modular - Can I add to it if I add on to my home?

Yes.  Additional modules can be added to your system up to the load limit of your inverter, and inverters can be added to expand the system.


11) How do I sell electricity back to the utility company?

Solar PV systems are tied to the utility grid through inverters.  Inverters track kilowatt-hour (kWh) production every day.  When a solar system produces more electricity than is used, the inverter sends the surplus energy to the grid, the electric meter spins backwards and the utility credits the owner for the surplus energy at the same retail rate that it charges for electricity during that period.  If your on an optional Time-of-Use net energy metering schedule, the utility credits your account during peak rate periods at several times off-peak rates.  This helps to reduce the size of your solar installation, and can zero out your electric bill over the course of each year.


12) What does a Solar PV System look like?

Solar Energy Supply designs, engineers and installs PV panels to minimize visual impact and maximize aesthetic appeal.  Flat roof-mounted systems are most common, but sometimes systems are installed on open ground away from a building or on tracking systems.  Solar energy Supply clients approve system design before installation.


13) What kind of permits do I need?

Solar Energy Supply builds turnkey solar systems.  We obtain all necessary permits for each system.


14) Does a Solar PV System have to meet local building code?

Yes. Your PV system must be inspected and meet local building and national electrical codes.


15) What is the process?

First, Solar Energy Supply inspects your site, building or home.  We evaluate a year's worth of electric bills to create a profile of annual energy needs.  Next, we design a system tailored for your site, and present the design in a proposal.  After you approve the design, sign the contract and make a deposit, Solar Energy Supply will schedule a convenient time to begin the install and start the required paperwork for local building permits and state rebates.


16) How long does it take to install?

Installation time depends on the size of the system.  Average residential systems rarely take more than one week to complete.


17) How do I maintain my Solar PV System?

Solar PV systems are designed and installed to be low-maintenance and repair-free.  They are solid state technology and have no moving parts.  Panels benefit from being hosed off twice a year, especially after long periods without rain.


18) How do I know if my system is working?

Your system is working if the green inverter light is on.  However, we offer solar monitoring of your solar system to monitor your system in real time for a small fee.  Solar Energy Supply also asks you to send consecutive electric bills every six months, so that we can analyze usage and actual system production.  Our dedicated staff is available to address any concerns long after system installation.


19) What do I do if something breaks?

Call us at (318) 397-4147


20) What if my roof needs repair after the Solar Panels are installed?

A roof inspection (and any necessary repair) is recommended prior to a PV installation.  If roof replacement is needed after installation, Solar Energy Supply can temporarily disconnect, remove and then reinstall the solar panels for an hourly fee.


21) Can I install a Solar PV System myself?

Possibly, if you have electrical systems experience, a contractor's license, love to carry heavy loads around rooftops and have a high tolerance for the government permit process.  You will also get a 15% lower state rebate.  As with any specialized job, there are good reasons to have expert solar installation, and Solar Energy Supply does the job quickly and economically.


22) Can Solar Energy Supply get solar panels?

Yes. Solar Energy Supply maintains strong relationships with major panel manufacturers and suppliers, and will be able to get panels to build projects within appropriate construction timelines.  In addition to having strong relationships with major panel manufacturers, we are proud to offer our customers with our own brand module, Montech.  Our module is "Made in the U.S.A." with the finest of materials tested to UL standards.
