Sign Up for Rooftop Solar
Seven easy steps to sign up for Cobb EMC Rooftop Solar
- Determine if the solar program makes sense for your home. View the solar tax incentives to get started.
- Estimate the cost of installing a photovoltaic system with a solar calculator.
- Apply for the program
- Fill out the Distributed Generation Facility Interconnection Agreement and Application for Interconnection of Distributed Generation Facility.
- Submit both of the above documents to Cobb EMC, along with a $100 check, in person or by mail at least 45 days prior to the date you intend to interconnect the distributed generation facility to Cobb EMC’s electric distribution facilities.
- 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.
- Read the full details regarding the Cobb EMC solar program.
- Your selected contractor should assist in all areas of the installation process, including the following:
- Choosing the right system for your home
- Filling out the “Distributed Generation Facility Interconnection Agreement” and “Application for Interconnection of Distributed Generation Facility” 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
- Making 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, at least 45 days prior to the date that member intends to interconnect the distributed generation facility to the Cooperative’s electric distribution facilities.
- Cobb EMC will perform the following steps:
- Review your interconnection application and distributed generation facility interconnection agreement (Appendix B)
- Perform an engineering review
- If necessary, install a new energy meter (Appendix A)
- Give final permission to operate (it takes 30 to 45 days to complete the permission process)
- In a few cases, Cobb EMC engineering system review may determine that additional system upgrades are necessary to support your renewable system. These upgrades may incur a cost and delay your installation and approval timeline.
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:
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.
Does installing a photovoltaic system make sense for my home?
Use the solar calculator to estimate what size solar system you need, how much solar panels cost, available rebates and your returns and payback period.
