You installed solar panels and used solar electricity, expecting your electric bill to drop way down. Maybe you thought it would hit almost zero. So when you open your monthly statement and see it's still high, it stings. You feel like something went wrong.
If you're wondering why your electric bill is still high after going solar, you're not alone. Solar panels work great, but several things can stop you from seeing the savings you expected. Here are the seven most common reasons and what you can do about them.
You're Using More Electricity Than Before
This happens to almost everyone, and most people don't even realize it.
You feel like the power is free. When you have solar panels, you know you're making electricity. So you stop worrying as much about turning things off. You run the AC a little colder. You leave lights on. You use more appliances without thinking twice. It all adds up fast.
Your life changed. Did you buy an electric car? Add a hot tub? Start working from home with a computer running all day? These things use a lot more power than you might think. An electric car alone can add 300-400 kWh to your monthly usage. A hot tub can add another 150-200 kWh. Even small changes, like getting a second refrigerator or upgrading to a bigger TV, push your consumption higher.
Your family grew. Maybe adult children moved back home. Maybe you're caring for elderly parents. More people means more showers, more laundry, more cooking, and more devices plugged in and charging. Each additional person can add 200-300 kWh per month to your usage.
What to do: Look at your old electric bills from before you got solar. Check the kilowatt-hours (kWh) you used each month, not just the dollar amount. If you're using a lot more kWh now, that's your answer. Compare your electric bill before and after solar panels to see exactly how your usage changed. Many people are shocked to find they're using 30% to 50% more power than they were when the system was installed.
Your Solar System Is Too Small
When your solar system was installed, it was sized for how much power you were using at that time. If you're using more power now, your system can't keep up.
Installers sometimes undersize on purpose. Some solar companies design systems that only cover 70% to 80% of your needs to hit a lower price point that closes the sale. They figure you won't notice the difference until after installation, and by then it's too late to change without paying thousands more.
Your needs outgrew the system. Even if your system was perfectly sized originally, life changes. The average American household increases its electricity use by 2% to 3% per year. After five years, that's 10% to 15% more power needed. Your panels haven't gotten bigger, but your needs have.
Production estimates were optimistic. Sales projections often use ideal conditions—perfect south-facing roof, zero shade, optimal tilt angle. Real-world performance is usually 10% to 20% lower than these estimates due to less-than-perfect conditions.
What to do: Check your solar system's monitoring data. Compare your actual monthly production to your actual monthly usage. If your panels are only producing 60% to 80% of what you need, your system is undersized. You may need to add more panels or rely on a battery to maximize what you already have.
You're Not Using Your Solar Power at the Right Time
This is the biggest problem for most people with solar electricity for home systems.
The timing problem is brutal. Your panels make power during the day when the sun is out. Peak production happens from 10 AM to 2 PM. But if you're at work and nobody's home, your house isn't using much electricity. Maybe just the fridge, a few standby devices, and the AC if it's running. That excess power—often 70% to 80% of what you generate—goes back to the electric company.
They give you almost nothing for it. The electric company might credit you 3 to 5 cents per kilowatt-hour for power you send back. In some states with new net metering rules, it's even less—as low as 2 cents per kWh.
Then you buy it back at full price. At night, your panels make zero power. But that's when you're home. You're cooking dinner (electric stove uses 2-3 kW), watching TV (200-400 watts), charging phones and laptops (50-100 watts each), running the dishwasher (1.2-1.5 kW), doing laundry (washer uses 500 watts, dryer uses 3,000 watts), and the AC or heat is running (3-5 kW). From 5 PM to 10 PM, your house might use 15 to 25 kWh. Now you have to buy power from the electric company at full price—often 25 to 35 cents per kilowatt-hour.
The math destroys your savings. You sell power for 3 cents and buy it back for 30 cents. That's a 10-to-1 loss. You're generating plenty of solar electricity for home use, but the timing makes it nearly worthless financially. Without a battery to save your daytime power for nighttime use, you're losing money every single day.
Your Solar Panels Aren't Working Right
Solar panels are tough, but things can go wrong that quietly kill your production.
Dirt blocks the sun. Dust, pollen, leaves, and bird droppings pile up and block sunlight. In dry climates or near farms, this happens fast. A dirty panel can lose 15% to 25% of its power output. If you haven't cleaned your panels in a year or two, you could be down 20% without realizing it.
Shade from trees creeps in. Trees grow about 1 to 2 feet per year. A tree that was fine five years ago might now shade your panels for 2 to 3 hours per day. Even partial shade on one panel can reduce the output of your entire string of panels by 30% to 50% because of how they're wired together in series.
They wear out slowly. All solar panels lose efficiency over time, typically 0.5% to 1% per year. If your system is 10 years old, it's making about 5% to 10% less power than when it was new. This is normal, but it still impacts your electricity bill with solar panels.
Equipment breaks silently. The inverter is the box that converts DC power from your panels into AC power for your home. Inverters typically last 10 to 15 years. If yours is failing, your whole system's production drops. A bad connection, a blown fuse, or a damaged panel can also cripple output. The scary part is these failures often happen without any warning light or alarm.
Weather damage adds up. Hail, high winds, and falling branches can crack panels or damage wiring. Even small cracks you can't see can reduce a panel's output by 10% to 20%.
What to do: Check your solar system's app or website. It should show how much power you're making each day. Compare this to the production estimates from when the system was installed. If you're producing 20% to 30% less than projected, something's wrong. Call a professional to inspect your system. Many problems are easy to fix once you identify them.
Your Electric Company Changed the Rules
Sometimes the problem isn't your solar panels—it's your electric company.
They charge more at certain times. Many electric companies now use Time-of-Use (TOU) pricing. They charge different prices at different times of day. They charge the most from 4 PM to 9 PM—peak hours when everyone gets home from work. Rates during peak hours can be 2 to 3 times higher than off-peak rates. This is exactly when your solar panels stop working and you need to buy power. It's not a coincidence. These rate structures are specifically designed to reduce the value of residential solar.
They pay you less for your power. Net metering policies—the rules that govern how much you're credited for excess solar power—are changing fast, and not in your favor. California's NEM 3.0 cut export credits by 75%. Hawaii ended net metering entirely for new customers. Arizona, Nevada, and other states have all reduced credits. What used to be a one-for-one credit is now often worth only 20% to 30% of retail rates.
You still pay fees no matter what. Even if you use almost no power, you still pay monthly fees just to be connected to the grid. These include connection charges, delivery fees, infrastructure charges, and various taxes. In some states, these fixed charges are $30 to $50 every month. In others, they're even higher. Electric companies are also lobbying to add special fees specifically for solar customers, claiming solar owners don't pay their "fair share" for grid maintenance.
Minimum bills are coming. Some utilities now have minimum monthly bills of $50 to $100 for solar customers, regardless of usage. This means even if your panels cover 100% of your power, you still pay that minimum. It's a way for utilities to claw back revenue they're losing to solar.
Winter Means Less Sun
In winter, you make a lot less solar power. Days are shorter, the sun is lower in the sky, and there's more cloudy weather.
The drop is bigger than you think. You might make 40% to 60% less power in December and January than in June and July. In northern states like Michigan, Minnesota, or Maine, winter production can drop by 70%. A system that makes 1,200 kWh in July might only make 350 kWh in December.
Snow makes it worse. If you live in snow country, panels covered with snow produce zero power. Even a thin layer of snow can block 90% of sunlight. Heavy snow can stay on panels for days or weeks. Some panels have heating systems or steep angles that shed snow quickly, but many don't.
The angles work against you. The sun is lower in the southern sky during winter. If your roof doesn't have the ideal tilt angle, this reduces production even more. Panels optimized for summer sun can be significantly less efficient in winter.
But your usage stays high. While your solar production drops, your power usage often stays the same or even increases. You're running the heater, using more lights because it's dark longer, and spending more time indoors using appliances. This creates a double hit on your electric bill with solar panels—you're making less and using more at the same time.
What to do: This is normal. It's not a problem with your system—it's just how the seasons work. Your bill will go up in winter and down in summer. Over a full year, your savings should still be significant. But if you want consistent bills year-round, you need a battery to store excess summer production for winter use.
Devices Use Power Even When They're "Off"
"Phantom" or "vampire" loads are devices that draw power even when you're not using them.
The list is longer than you think. TVs, cable boxes, streaming devices, gaming consoles, sound bars, coffee makers, microwaves, toasters, phone chargers, laptop chargers, printers, routers, smart home hubs, video doorbells, security cameras—all of these use power 24/7 in standby mode, always ready to turn on instantly.
You paid for solar power they're wasting. Every watt wasted by phantom loads is a watt your expensive solar panels have to replace. If phantom loads are using 100 watts constantly (2.4 kWh per day), that's 876 kWh per year—roughly 10% of a typical home's usage. You spent thousands on solar panels, and a meaningful chunk of that power is going to devices you're not even using.
What to do: Unplug things you're not using. Use power strips that you can turn off completely with one switch. Plug your TV, cable box, gaming console, and sound system into one power strip, then turn it off when you're done watching. Do the same for computer equipment, kitchen appliances, and phone chargers. Smart plugs can automatically cut power to devices on a schedule. These simple steps can recover 50 to 100 kWh per month—power your solar panels are already making, but that's currently being wasted.
The Real Fix: Add a Battery to Your Solar System
All these problems come down to one thing: you can't control when you use your solar power. You can't control the weather or when the sun sets. You can't control what your electric company charges.

Common Questions
Q1: How much will solar panels lower my electricity bill?
Solar panels reduce utility bills by 40% to 70% for most people. How much you save depends on system size, local electricity prices, and battery use. Battery users save more by using their own power instead of buying costlier nighttime power. In California, where electricity is expensive, you can save $2,000 to $3,000 per year or more.
Q2: Can solar panels make my electric bill zero?
Getting to zero is hard. Even if your solar panels generate all your power, you must pay monthly grid fees. Connection, delivery, and tax expenses average $20 to $50 per month. You need large solar panels and a battery to cover your power demand and monthly expenses to get close to zero.
Q3: How long does it take for a battery to pay for itself?
A battery pays for itself in 7 to 10 years through electric bill savings. Much depends on where you live. If your electric company charges high rates at specific times or has frequent power outages, a battery pays for itself more quickly. The 30% federal tax credit also cuts the payback time.
Q4: Why does my solar system make different amounts of power each month?
Solar panels provide more power in summer than winter. This is normal. Winter brings shorter days and lower sun angles. Winter may generate 40% to 60% less power than summer. Cloudy or rainy days cut power by 60% to 80%. Solar systems generate adequate power year-round, not the same amount monthly. Batteries store extra summer power for winter use.
