Solar true-up charges come once a year for people with solar panels. They balance out how much electricity you used and how much your solar panels made. If your panels made more energy, you get credits.

These credits can lower what you owe on your bill. Sometimes, if your panels give lots of extra power to the grid, you might even get money back.

Your electric company looks at all the power you used and made after one year. This helps them see if you need to pay more or if they owe you for extra energy. Your solar system’s performance throughout the year affects this final bill.

It records everything in a document called a true-up statement.

Embarking on a deep dive into your annual True-Up statement unlocks the complexities of solar energy economics, shedding light on how much you’ve saved or owe after a year with solar panels.

This pivotal document is your financial compass for navigating the ins and outs of net energy metering and its implications on your home’s energy dynamics.

What is a True-Up Statement?

A true-up statement arrives once a year from your utility company. It checks how much electricity your solar panels made and how much you used from the power grid. Think of it like settling up a tab after a year of trading energy with the utility.

Your solar system might produce more power than you need, so this extra goes back to the grid as credits. The true-up statement tallies these credits against what you pulled from the grid when your panels weren’t enough.

The statement presents two important numbers: total energy sent to the grid and total taken from it over 12 months. If you gave more than you got, there might be some money coming back to you or a lower bill next cycle.

But if it’s the other way around, expect a bill for that difference. Now let’s see how net energy metering affects your electric charges on this balance sheet.

How Does Net Energy Metering Work?

Solar panels often make more electricity than a house needs during the day. This extra power goes back into the energy grid for others to use. Your electric meter tracks this. It spins backward when you send power to the grid, giving you energy credits.

At night or on cloudy days, if your solar doesn’t make enough power, you draw electricity from the grid and use up credits.

After 12 months, your utility company looks at all the power your solar sent to the grid and all you took out. They balance it in a True-Up statement. If you gave more than you got, they might owe you! If it’s the other way around, then there’s a bill to pay.

Now let’s dive into what makes up these charges – first up are electric charges.

Details of Electric Charges

Net energy metering helps track the power you draw from and send back to the grid. Your electric charges on the True-Up statement reflect this exchange of energy. These charges show how much electricity your home used over a year.

They are based on kilowatt hours (kWh) consumed beyond what your solar system produced.

Utility companies, like PG&E, include delivery and transmission fees in these electric charges. Delivery fees cover moving electricity from power plants to your home through high-voltage lines and distribution networks.

Transmission fees pay for using the infrastructure that carries electricity across long distances. Together, they make up part of your annual energy costs recorded in the True-Up bill.

Details of Gas Charges

Moving from electricity to gas, your solar true-up also includes natural gas usage. Gas charges reflect the amount of gas you used over the last year. You see these as therms on your bill.

The price for each therm is set by PG&E and changes with market prices.

Your true-up statement shows how much gas you bought from PG&E. It counts every therm used in your house for heating, cooking, or hot water. This part of the bill is separate from electric charges.

If you use less gas, your annual cost goes down. Using more means higher charges at the end of the year.

Factors Influencing Your True-Up Bill

Explore the various elements that might affect your annual true-up bill, ranging from household energy habits to system design and performance. Understanding these factors is crucial for managing costs and optimizing the benefits of your solar investment.

Causes of High True-Up Bills

High true-up bills shock many homeowners with solar panels. Understanding what drives these costs up is crucial.

  • Less sunshine: Cloudy weather means your solar panels make less electricity. If they don’t produce enough, you buy more power from the utility company.
  • More power use: Using lots of appliances or electric vehicles can lead to higher energy consumption. This increases your reliance on the grid, especially during peak hours.
  • Inefficient energy use: Old, energy-hungry devices drain more electricity. Replacing them with energy-efficient ones can help lower your bill.
  • Solar system issues: Sometimes there’s a problem with your solar PV system that causes it not to work right. Fixing any faults quickly keeps your system running well.
  • Changes in rates: The cost of electricity changes with demand and fuel costs. If rates go up, so will your true-up bill, especially if you’ve used more grid electricity than expected.
  • Time-of-use rates: Electric companies charge different prices throughout the day. Using lots of power during expensive peak hours can add to your true-up charges.
  • Expanding your home: Adding rooms or features usually means you’ll need more power. Without boosting your solar capacity, you will likely draw and be charged for extra grid power.
  • Plant outages: When power plants shut down unexpectedly, everyone may pay more for their limited electricity. These prices affect annual true-up charges as well.
  • Policy changes: New rules from entities like the California Public Utilities Commission (CPUC) can alter how much you owe or save with solar energy.

How to Minimize Your True-Up Bill?

Knowing the causes of high True-Up bills can lead you to take steps to decrease your annual statement. It’s smart to use strategies that cut down on your True-Up costs throughout the year.

  • Watch your energy use. Keep an eye on how much electricity you consume, especially during peak hours when it costs more.
  • Make more power than you use. Try to generate more solar energy than what your house needs. This way, you’ll have extra credits to reduce your True-Up bill.
  • Add a battery storage system. With this, you can store solar power for times when the sun isn’t shining, like at night.
  • Use appliances wisely. Run things like dishwashers and washing machines during off-peak times to save on energy charges.
  • Upgrade to efficient devices. Choose gadgets and home systems labeled as energy-efficient because they use less power.
  • Check for drafts. Seal any leaks in windows and doors so you don’t waste heat or air conditioning, which saves energy.
  • Install LED lights. Replace old bulbs with LEDs, which last longer and use much less electricity than regular ones.
  • Adjust the thermostat. Set it a few degrees lower in winter and higher in summer so your heating and cooling systems work less.
  • Keep up with maintenance. Make sure your solar panels are clean and that nothing blocks them, like trees or dust.
  • Review rates often. Look at PG&E’s pricing plans every year and pick the one that offers the most savings for your situation.

Implications of True-Up Charges

Understanding the implications of solar true-up charges is essential for homeowners with photovoltaic systems, as these fees can significantly affect both your monthly budgeting and annual financial reconciliation with the utility company.

They represent the culmination of a year’s worth of net metering, showcasing how your energy production and consumption levels balance out over time.

Effects on Monthly Energy Charges

Solar customers often see lower monthly energy charges. They usually pay small service fees, taxes, and any additional grid connection costs each month. Their true-up bill arrives once a year, covering the full cycle’s electricity usage.

This yearly charge reflects the difference between solar energy produced and the power used from the utility company.

A well-designed solar system can help keep these monthly expenses low by providing most of the home’s energy needs. If you produce enough clean energy, your monthly charges might just be minimal grid connection fees.

Remember that how much sun your panels get will change how much you save each month.

Impact on Annual Power Charges

True-Up charges can make your annual power bill go up or down. If you use more electricity than your solar panels produce, you will owe money at the end of the year. But if your panels make more energy than you use, you could get credit instead.

This single invoice includes all the power charges and credits from the whole year.

Your solar system’s performance affects your True-Up bill too. More sunlight means more energy produced and possibly lower annual costs. Keeping track of how much electricity you use helps manage these yearly charges.

Remember to think about energy efficiency to save on power costs throughout the year.

Components of a Solar System and Their Impact on True-Up

Solar panels, inverters, and batteries are major parts of a solar system. Each part affects your true-up charges. The number of solar panels decides how much electricity you can make.

If you have more panels, you might produce enough power to lower your true-up bill. Inverters change the sun’s energy into electricity for your home. Good inverters mean less energy is lost when it changes from sunlight to power.

Batteries store extra solar energy for later use. When the sun isn’t shining, stored energy keeps your lights on without using grid power. This can also help keep your true-up costs down because you’re using less electricity from the utility company.

Each piece must work well together for maximum savings on your bill. A bigger or smarter system may cost more at first but could save money over time by reducing what you owe in true-up charges.

Common Questions About True-Up Charges

Unraveling the mystery of true-up charges often begins with a set of common inquiries from solar consumers perplexed by their bill. As we delve into the popular queries, essential insights emerge to help demystify the nuances behind these financial reconciliations.

Why is My True-Up Bill So High?

Your True-Up bill might be high for several reasons. Sometimes, you use more electricity than your solar panels produce. This can happen if you’ve added new appliances or had more people living in your house.

Even small changes like using the air conditioner more often can increase your bill.

Fixed fees and charges that everyone pays are also part of the True-Up bill. These fees help maintain the electric grid and cover other costs. Your bill includes these no matter how much energy you produce or use.

If these fees go up, so will your True-Up bill.

If you’re using more gas as well, this will make the total amount higher too. Annual costs for being connected to the grid are included in your True-Up statement from PG&E (Pacific Gas and Electric Company).

These yearly expenses don’t change even if you save energy throughout the year.

Lastly, if net energy metering (NEM) rules change, it could affect your bill too. The NEM program decides how much credit you get for extra energy sent back to the powerlines. Changes in this system may impact how credits and charges add up over time on your statement.

What Can I Do to Get Rid of My True-Up Bill?

Check your energy habits to lower your True-Up bill. Start by using less power during peak hours. Turn off lights and appliances when not in use. Consider upgrading to energy-efficient bulbs and devices.

Think about installing a battery storage system to save excess solar energy for later use.

Look into DC Solar Electric’s options to cut or even eliminate True-Up costs. They might suggest adding more panels if your solar production is low. Also, they can help you find out if you’re eligible for rebates or tax credits for making green upgrades at home.

The Future of Solar True-Up Charges

As the landscape of renewable energy evolves, solar true-up charges are poised to undergo significant changes that will shape how consumers manage and offset their electricity use.

The rise in self-consumption and policy shifts such as California’s proposed 2023 Net Billing Tariff suggest a dynamic path forward for homeowners with solar installations.

The 2023 Net Billing Tariff

The 2023 Net Billing Tariff changed how solar customers in California get paid and billed. Starting April 15, solar users now face a new billing system. They earn credits for power they send to the grid but also pay for electricity they use.

This setup makes sure everyone using the grid helps support it.

Solar systems still help save on energy costs even with these changes. Customers should understand their usage patterns and consider battery storage to keep bills low. This new rate plan pushes forward the transition to cleaner energy sources while balancing grid needs.

The role of self-consumption will become more crucial under this tariff.

The Role of Self-Consumption

Self-consumption lets you use solar energy as soon as it’s made. Your solar panels catch sunlight and turn it into electricity for your home. You can run your appliances right away with this clean power.

Any extra energy goes to a battery in your house. This stored power is there for you when the sun isn’t shining.

Home batteries play a big part in managing what you consume versus what you send back to the grid. With a smart setup, they can charge during off-peak hours when rates are low and provide power during peak times.

This reduces reliance on the utility services for electricity and helps lower true-up charges at the end of the year.


Solar true-up charges balance the year’s energy books. They show how much power you made and used. If your panels didn’t cover your use, you’ll owe money. Generate more or use less to shrink your bill.
