Rooftop Solar

Rooftop Solar

Cobb EMC has long encouraged the efficient use of electricity and renewable energy technologies. As a Cobb EMC member, you can choose to participate in Rooftop Solar.

Benefits of Rooftop Solar

  • Highly reliable and needs little maintenance
  • Environmentally safe technology
  • Helps ensure our energy future

For detailed information on Rooftop Solar, read our Distributed Generation Policy and Interconnect Agreement. See the rate schedule that applies to members participating in Rooftop Solar. View a list of solar contractors.

How To Get Started

  1. Determine if the solar program makes sense for your home. View the solar tax incentives to get started.
  2. Estimate the cost of installing a photovoltaic system with a solar calculator.
  3. Hire an experienced, qualified contractor who will properly install your system. We recommend that you request bids from at least three contractors. Cobb EMC has several contractors in our area from which to choose.
  4. Your selected contractor should assist in all areas of the installation process, including the following:
    • Determining if your home receives an adequate amount of sun for a system.
    • Properly sizing and choosing the right system for your home.
    • Filling out the Distributed Generation Facility Interconnection Agreement (completed by member) and Application for Interconnection of Distributed Generation Facility (completed by contractor – provided by email after member completes interconnect agreement) to connect your system to Cobb EMC. This process needs to be completed as soon as possible in order to expedite the process after passing local city or county inspections.
    • Completing installation of your new system.
    • Make necessary arrangements with building officials to complete county and city inspections.
    • After the inspections, contractor/or member submits all required paperwork to Cobb EMC, including copy of the line diagram of the system and a copy of the final building permit, along with $100 check for the application fee.
    • The step above must be completed at least 45 days prior to the date that member intends to interconnect the distributed generation facility to the cooperative’s electric distribution facilities.
  5. Cobb EMC will perform the following steps:
    • Review your interconnection application and distributed generation facility interconnection agreement.
    • Process the $100 application fee that is sent in with the interconnect agreement for the net meter.
    • Get a copy of the final city or county check-off for the system installed.
    • Once Cobb EMC has the interconnect agreement, application fee and final check off, we then set the net meter at the members home to complete the process.

I’ve installed my new photovoltaic system, now what?

With your newly installed photovoltaic system, you’ll want to monitor your energy use to see how your solar system works. Below are some tips to get started:

  • View your electric use and pay your Cobb EMC bill online
  • See how much energy you produced via new energy metering.
  • See graphs of your monthly, daily and hourly electric use.
  • Discover more ways to save energy at home.


About Solar Photovoltaic (PV) Systems

How does photovoltaic work?

Photovoltaic is a solar power technology that uses arrays of photovoltaic cells to convert light from the sun directly into electricity. Solar cells produce direct current (DC) electricity from light, which can be used to power DC equipment or to recharge a battery. Adding batteries to your photovoltaic system will also provide a secure backup source of electricity for your home. An inverter, which converts DC electricity to alternating current (AC) electricity, is required to power almost all electricity uses in the home.

The basic photovoltaic cell typically produces only a small amount of power. To produce more power, cells can be interconnected to form modules, which can in turn be connected into arrays to produce even more power. Because of this modularity, photovoltaic systems can be designed to meet any electrical requirement, no matter how large or how small.

Benefits of photovoltaic

  • Reliable and needs little maintenance
  • Environmentally safe technology that converts sunlight directly into electricity
  • Helps ensure our energy future by tapping into an infinite, renewable power supply
  • Produced domestically, strengthening our economy
  • Modular and flexible in terms of size and applications
  • Helps meet the demand and capacity challenges facing many energy service providers
  • Can be installed to just about any building type

Factors that affect cost

Depending on your specific need and location, there are a number of factors that affect cost-effectiveness, including:

  • System size: Because of economies of scale, large systems cost less per watt than small systems.
  • Installation complexity: More complex installations, including mounting systems on racks, working around obstructions or on tile roofs can be more expensive.
  • System production: Installing your system at the optimal orientation and tilt will maximize system production. The more energy your system produces over time, the lower the cost per kilowatt hour.
  • Operation and maintenance: Compared to other distributed energy technologies, operation and maintenance costs of photovoltaic systems are relatively low. Costs may include occasional cleaning of photovoltaic modules, regular visual inspections and possible repair or replacement of the inverter and/or components after a number of years.
  • Financial incentives: Federal tax credits and other incentives may be available to help lower the effective costs of investments in photovoltaic systems.*

*Consult with your tax advisor about the applicability of receiving a Federal Tax Credit and any available state credits.

What are the current limitations of solar power?

  • The payback period can be very lengthy depending on costs to install.
  • Solar energy output is not available all the time, so it is less reliable than other sources.
  • Battery storage backup is very expensive.
