By selling excess energy back to the grid, you can reduce your utility bills and potentially even earn money from your solar panels, making them a more financially viable investment.

Factors to Consider Before Starting Solar Net Metering

While solar net metering can be a great way to reduce electricity costs, there are several important factors to take into account before deciding to participate. Here are key points to consider:

1. Net Metering State Laws

• State Regulations: Net metering is not available in all states, and policies vary significantly across regions. Currently, 44 states and the District of Columbia have mandatory net metering policies. However, some states like Alabama, Mississippi, Tennessee, and South Dakota do not have any net metering laws.
• Limited Options: In states like Texas and Idaho, net metering is not mandatory at the state level, but certain cities or utility providers may offer net metering programs. Be sure to check with your local utility company to see if it’s available.

2. Solar Energy Rollovers and Reimbursements

• Credit Rollovers: Not all net metering programs allow you to roll over unused credits month to month. In some cases, if you generate more power than you consume in one month, the surplus may be carried over, but others may limit this to a certain number of months or require you to use them within a set timeframe.
• Unused Credits at Year-End: It's crucial to find out whether any unused credits at the end of the year will expire. Some programs let you carry over credits indefinitely, while others might require you to forfeit them after a certain period.
• Reimbursement Rates: If your utility company does not allow rollovers or expires unused credits, you might be reimbursed for them at a lower rate than what you would typically pay for electricity. Some states pay the retail rate for excess energy, but about 10 states pay "avoided cost rates," which are often much lower and are calculated based on the utility’s cost to generate the electricity.

3. Monthly Connection Fees

• Even if you are credited for surplus energy, many utilities charge a monthly connection fee to maintain your access to the grid. These fees are typically fixed and can still be part of your monthly electric bill, even if you generate more energy than you consume. Be sure to understand the cost of these fees, as they can affect your overall savings.

4. Utility's Compensation for Excess Power

• As mentioned, the compensation for surplus energy varies. Many utilities pay the retail rate, which means you are credited the same amount as you would have paid for the energy you consume. However, some states may offer a lower compensation rate, which can affect the financial benefit of selling back energy.
• Avoided cost rates (lower than retail rates) are common in about 10 states, and these rates are often based on the power company’s production cost rather than the price you pay for electricity. This lower rate may mean smaller savings in some areas.

Before committing to solar net metering, it’s important to fully understand the rules and conditions specific to your state and utility provider. Make sure you are aware of whether excess energy credits can roll over, what happens to unused credits at the end of the year, how much your utility pays for your excess power, and any associated fees that may impact your savings.

Limits on Selling Solar Energy

Before installing solar panels, it's essential to understand any potential limits your utility company or state may place on the amount of surplus electricity you can sell back to the grid. These limits vary by location and can influence the size of the solar panel system you might choose to install.

1. State and Utility Limits on Selling Excess Energy

• Many states have limits on how much energy can be sold back to the grid. These limits are typically set to encourage the use of residential solar panels, not large-scale commercial solar energy farms.
• In most states, there are caps for the amount of surplus energy you can sell, such as:
  • 1 megawatt (MW) in many states.
  • Smaller caps in places like Vermont and Wisconsin, where systems are capped at 20 kilowatts (kW).
  • More generous caps in Massachusetts (10 MW) and New Mexico (80 MW).
  • A few states, such as Arizona, New Jersey, and Ohio, have no limit for net metering.

2. Considerations When Sizing Your Solar System

• While solar net metering rules are important, they shouldn’t be the primary factor when deciding on the size of your solar panel system.
• More significant factors include:
  • Roof orientation and angle for optimal sun exposure.
  • Available space for installing panels.
  • Average electricity usage to determine how much energy your system needs to produce.

3. Changes in Policies

• Keep in mind that solar policies can change, so it's important to stay informed. For example, a recent law in Virginia limits new residential solar installations to the size needed to meet annual consumption for the past 12 months.

4. Anti-Solar Utility Companies

• Some utility companies may try to discourage solar adoption. This is often because utilities fear losing customers who no longer rely on them for electricity, as solar energy reduces the need for power plants.
• In some areas, utilities may penalize solar users. For example, Salt River Project in Arizona introduced a $50 monthly charge for solar customers.
• Some utilities may also try to reduce or eliminate solar incentives, making it more difficult for homeowners to save money.

5. Support for Solar Energy

• Solar energy continues to grow in popularity, and there are many champions for solar energy, from local governments to national policies prioritizing clean energy.
• Trends in favor of solar include:
  • Falling solar panel prices.
  • Local rebates and incentives in many areas.
  • Financing options that make it easier to afford solar installations.
  • Mature and reputable solar installers to guide homeowners through the process.

While there are limits on how much solar energy can be sold back to the grid in certain areas, solar energy remains a great option for homeowners looking to reduce their energy bills and reduce their carbon footprint. It's important to keep up with local rules and policies, work with a reputable installer, and consider factors beyond net metering when designing your system. Solar energy is gaining momentum, and many governments and utilities are supporting its growth.
