Effective March 1, 2022, South Central Power has transitioned from net metering to net billing. This means the Cooperative will be purchasing excess power at a fair-market rate established annually that better reflects the true cost of the energy to the Cooperative's membership.
Member-Owned Solar FAQ
Before choosing a solar system, check out these tips.
Be sure that your home is as energy efficient as possible:
- You may want to get a home energy audit to help determine which improvements will be most beneficial
- Investing in energy efficiency provides a faster return on your investment
- By improving your home’s energy efficiency first you will reduce your overall energy use and may reduce the size of PV system—that saves more money.
Make sure your roof is in tip-top shape:
- If yours is older, you may need to repair or replace it before installing solar
- Remember, a solar PV system may last up to 30 years, so be sure your roof will last, too
Research:
- Research solar and solar contractors thoroughly before investing in a system
- Get at least 3 quotes before choosing one
Be sure to work closely with South Central Power energy advisors for advice and assistance on interconnecting with the grid:
- We can provide information and history of your energy usage that can help you size your system and evaluate savings
- Coop staff has experience in working with other member-owners and solar contractors
If your house is not ideal for solar, you rent your home, or you just aren’t ready to make a big investment, there are other options. Talk to us about our community solar program. Find out more on our Community Solar page.
To begin, you can look at factors such as:
- Which direction your home faces
- The condition of your roof
- Obstructions such as trees and other buildings that may block the sun during the peak generation period of 9 a.m. to 3 p.m
Solar contractors can provide a more detailed analysis on what to expect, and your cooperative can offer advice, too.
Certified PV products and systems generally are reliable:
- They have a life expectancy of about 30 years
- Manufacturers test PV panels for hail impact, high wind, and freeze-thaw cycles to represent real-life situations
- Most manufacturers offer 20- to 25-year warranties for panels; extended warranties may be available at an extra cost
Little maintenance is required; occasionally it may be necessary to rinse modules off with water to remove dust and grime. Other components, like inverters, may have a shorter life. PV panels may outlast the roof they are attached to. Make sure your roof is in good shape or budget for replacement during the life of the system.
The payback period can range from fewer than 10 years to more than 20 years, depending on:
- The system cost
- Available rebates and incentives
- The amount of electricity produced
- The retail price of electricity you purchase from your cooperative
Yes. There is a federal tax credit of 30% through 2019, then a slow phase-out of the credit by the end of 2021. In addition, there may be:
- State or local income tax credits
- Property tax exemptions
- Rebate programs from government agencies
These vary by state, city, and utility, and may also depend on whether the system is purchased or leased. Find information about Ohio’s programs on the DSIRE website. Be sure to consult with your financial and tax advisor.
The price of PV components varies depending on:
- The size of the system (generating capacity)
- Type and quality of the components purchased
- Complexity of the system selected
The good news for consumers is that the cost of PV has declined dramatically, while the technology has improved, equally dramatically. Installation costs depend on the size and complexity of the system, but also on the home layout and construction. For example, a simple, south-facing roof allows for an easier install than a roof with hips and valleys. In addition, some homes require structural or wiring upgrades.
Average costs:
- An average 4 kW system may cost between $10,000 and $20,000, before credits and incentives
- This is based on a typical installed cost of $2.50 to $5 per watt of distributed generation capacity
- To determine your costs, look for online calculators to help you estimate your pricing, and also get bids from reputable installers
Grid-connected PV systems are connected to the cooperative’s power lines. That means electricity can flow both ways (to your home from your cooperative, and from your PV system back to the electrical grid). Particularly on sunny days when your energy use may be low, your system may produce excess energy that can be purchased back by South Central Power.
Most grid-connected PV systems shut down to prevent backfeeding electricity into de-energized power lines that may have fallen or that line crew members may be working on. It’s important to have this shut-down feature to prevent injuries—and even death — to those working on the line.
