How Does Solar Power Work On A House

Can A Home With Solar Panels Use A Generator

How do solar panels work for your home?

One of the biggest misconceptions about solar panels is that theyll keep your house running when utility power goes out. However, contrary to popular belief, solar panels actually cant send electricity to your house when the grid is out.

Why? Well, its a safety thing. Grid-tied solar panels send electricity to utility lines, and if they arent shut off during a power outage, they would continue to send electricity, posing a threat to utility workers fixing the lines. That means, in order to prevent any harm, your solar panels go out when the grid does.

So if you want your lights to stay on when the rest of your neighborhood goes dark, you need a backup plan. The good news is, homes with solar panels can be connected to gas-powered generators, but how it works can be a bit tricky.

Paying For What’s Free

The sun’s rays are available to anyone, but it takes a lot of expensive equipment to turn them into power. But solar panels are now among the least-expensive forms of renewable energy.

Most large-scale solar projects are now significantly cheaper than coal plants . Huge savings on a big scale may not yet translate to smaller projects like homes. But if you’re serious about making the switch, don’t let that discourage you there might be ways to make it happen.

Energy-related incentives and rebates vary so much, and change so frequently that anyone considering a solar home conversion should take a close look at state-specific benefits. The right combination of grants, tax credits and per-watt rebates might make the initial investment more affordable than many homeowners think.

In 2020, Congress passed an extension on the Solar Investment Tax Credit a so-called “solar tax credit” for newly installed solar panel systems. It reduces federal income taxes by allowing for a percentage of the cost of a photovoltaic system. There is no maximum credit. The ITC, though, expires in 2024 unless it’s renewed by Congress again .

If your solar panels make more power than your house uses, you can sell your extra power back to the grid. Companies that install residential solar power tout this benefit as an easy way to recoup your investment, and it would be attractive to buyers, but the results can vary depending on where you live.

Solar Heating For Your House

There are two types of solar energy heating: passive solar and active solar.

Passive solar relies on the design of the house to heat your home without the use of mechnical devices, while active solar uses various technologies such as photovoltaics and solar thermal heaters.

For most homes, active solar heating using photovoltaics and a heat pump is the best approach. While there are other types of solar heaters available, many of them are fairly exotic and rarely used. Finding an experienced installer may be difficult.

Heat pumps, however, are becoming commonplace and can often be installed by any contractor that already installs central air conditioners. Plus, many utilities are offering rebates on high efficiency heat pumps.

Where Does The Energy Go First

Before we get too far into this, its important that we refer back to some of the information that we covered above. When sunlight first hits your solar panels, its captured as DC electric current. This current then flows through the wiring to specialized inverters located near your homes electrical panel. The inverters transform the electrical current from its DC form into AC current so that it can be used, stored, or sent off to the grid.

After its transformed from DC to AC, the next place that it goes depends entirely on how you have your solar energy system installed. If you have a battery bank installed on your home, the current will travel in a different path than if you dont have one installed.

What Are Your Solar Electricity Needs

A glimpse into how solar panels work

Your solar needs can be determined from your monthly electricity bills. Study your consumption patterns over the year and determine which months see higher consumption rates and figure out the causes.

Additionally, accommodate future plans that might bring large energy requirements. For example, if you plan to get an electric car, your power needs will increase.

Solar Panels Are More Efficient Than Ever Before

Solar panels function best when theyre exposed to unobstructed sunlight all day long, from sunrise to sunset. In reality, however, few places offer ideal solar panel conditions.

Thanks to modern solar panel technology, solar panels can still be efficient when theyre in sub-optimal conditions. A modern solar panel may produce more energy from 4 hours of direct sunlight than an old solar panel would produce from 12 hours of direct sunlight.

What Is The Environmental Impact Of Solar Panels

Benefits of solar beyond reducing carbon emissions are:

  • Solar panels today are being built to be 100% recycled at end of life
  • Solar panels create enough energy in 2 years to offset energy needed to manufacture a panel.
  • Major sources of silicon are silica sand, an abundant material on Earth
  • Solar panels use 0 gallons of water to produce power

Can A House Run On Solar Power Alone

Practically, it is not often possible. This is because solar only works when the sun is shining – which means when it is cloudy or nighttime, they do not generate electricity. There are some battery solutions to provide power during these times, but they still tend to be quite expensive. Most homes with solar panels still rely on the grid from time to time.

Solar And Your Utility Meter

Residential Solar Power 101: How home solar power systems work

Another important component of your system is your utility meter. It will track how much solar electricity your home produces. The more electricity your panels generate, the less electricity you will need to buy from your utilityand the lower your utility bills will be.

Step : A Net Meter Measures Usage

On cloudy days and overnight, your solar shingles or panels may not be able to capture enough sunlight to use for energy conversely, in the middle of the day when nobody is home, they may collect surplus energymore than you need to operate your home. Thats why a meter is used to measure the electricity flowing in both directionsto and from your home.Your utility company will often provide credits for any surplus power you send back to the grid. This is known as net metering.

How Does Sun Exposure Affect Solar Panel Efficiency

It is important that your solar panel array are installed in areas that receive good insolation throughout the day, free from as much shading from trees or neighboring obstructions as possible. This will ensure your system is as productive as possible, given the site conditions.

More sun exposure means more photons hit the solar panel, thereby freeing more electrons and creating a stronger current, meaning more power for your home.

Why May Solar Panels Not Work

How does solar energy work?

Youve installed your solar panels but the system just doesnt seem to generate any energy. What can you do?

Unfortunately this problem known as zero power output can be caused by a damaged inverter, faulty charge controller or simply your solar panels not working.

Check if your inverter is up and running. This works as a power adapter and is crucial to converting the energy of the sun into a format home appliances accept.

If it still doesnt work after inspecting the inverter, youll have to contact the company that supplied it. Do the same with your charge controller.

Other reasons include nearby trees casting a shadow on your solar panels when the sun is out and your system overheating this can be fixed by connecting extra modules.

How Does A Solar Panel System Work

Here’s an example of how a home solar energy installation works. First, sunlight hits a solar panel on the roof. The panels convert the energy to DC current, which flows to an inverter. The inverter converts the electricity from DC to AC, which you can then use to power your home. It’s beautifully simple and clean, and it’s getting more efficient and affordable all the time.

However, what happens if you’re not home to use the electricity your solar panels are generating every sunny day? And what happens at night when your solar system is not generating power in real-time? Don’t worry, you may still benefit through a system called “net metering.”*

A typical grid-tied PV system, during peak daylight hours, frequently produces more energy than one customer needs, so that excess energy is fed back into the grid for use elsewhere. The customer who is eligible for net metering may receive credits for the excess energy produced and can use those credits to draw from the grid at night or on cloudy days. A net meter records the energy sent compared to the energy received from the grid. Read our article on net metering and how it works.

How Does Weather Affect Solar Energy

Weather conditions can impact the amount of electricity a solar system produces, but not exactly in the way you might think.

Perfect conditions for producing solar energy include a clear sunny day, of course. But like most electronics, solar panels are actually more efficient in cold weather than warm weather. This allows the panel to produce more electricity in the same amount of time. As the temperature rises, the panel generates less voltage and produces less electricity.

But even though solar panels are more efficient in cold weather, they don’t necessarily produce more electricity in the winter than in summer. Sunnier weather often occurs in the warmer summer months. In addition to fewer clouds, the sun is usually out for more of the day. So even though your panels may be less efficient in warm weather, they’ll still likely produce more electricity in summer than in winter.

What Do I Receive For My Exported Solar Electricity

While you wont receive cash for your exported solar electricity, you will receive a credit on your electricity bill. This is called a feed-in tariff and in Australia, the amount you will receive will vary state-to-state, and also depending on other factors such as when you installed your solar and the time of energy generation.

While this may seem little, as weve explored in previous blogs, the value of solar should be placed in the savings generated by the amount of electricity youre displacing from the grid, not from the feed-in tariff youll receive.

As your solar provider, Infinite Energy can apply for the feed-in tariff on your behalf, making the entire solar process as seamless as possible.

How Does Solar Energy Work?

When it comes to creating and supplying your own electricity, there is possibly no greener technology more accessible and efficient than solar panels.

For the most part, going off-grid with solar panels is 100% possible. However, it is just one piece to the puzzle.

In order to maintain a healthy prolonged off the grid lifestyle, you will need some place to store all that solar energy generated by your solar panels.

And just like solar panels are the most accessible and efficient for electricity production, solar batteries/solar power stations, are the absolute best technology out there to store your off-grid solar energy.

So in essence, you can go off-grid with solar panels and some sort of storage system.

Do Some States Get More Solar Energy Than Others

Obviously, some states get more sun than others. So the real question is: if weather can affect solar energy production, are some states better candidates for solar energy than others? The short answer is yes, but not necessarily because of weather.

Take clouds for example. Anyone who has been sunburned on a cloudy day knows that solar radiation penetrates through clouds. For that same reason, solar panels can still produce electricity on cloudy days. But depending on the cloud cover and the quality of the solar panels, the efficiency of the solar panels electricity production commonly drops from 10 to 25 percent or more compared to a sunny day.

In other words, solar power can still work well in typically cloudy, cold locations. New York, San Francisco, Milwaukee, Boston, Seattle – all of those cities experience inclement weather, from rain and fog to blizzards, yet they’re also cities where people see huge savings by getting solar.

No matter where you live, solar energy can be an excellent investment and an excellent way to help combat climate change. How much you’ll save – and how quickly you’ll see a return on your investment in a particular state – depends on many factors, like the cost of electricity, solar incentives available, net metering, and the quality of your solar panels.

Talk To A Solar Panel Contractor To Determine Your Best Option

Ultimately, solar panel installation companies have worked with all types of properties including properties surrounded by trees. They know how to maximize the efficiency of your solar panels. Theyll be able to determine if you should cut down trees, trim trees, or just leave them there. Request a free estimate and see what your local solar panel company says about your tree situation.

Benefits Of Home Solar Power And Battery Storage Systems

We recommend making your home energy efficient before installing at-home solar power and battery storage systems. This will help you determine how many solar panels youll need for maximum cost-savings and energy savings. You can learn more about how home solar and storage can save you money at cpuc.ca.gov/nem. Battery storage allows you to store energy generated during off-peak time-of-use periods and use it later in the evening to avoid grid usage during on peak periods.

Multifamily properties can also install solar power systems that serve apartments and common areas, like community rooms, on-site laundry, parking areas, etc. Property owners can set up virtual net energy metering with your electric utility to have bill credits from on-site solar production split between tenants and the property owner. No matter the home type, Californians can install solar power to help reduce monthly energy costs.

Beyond the benefit to your wallet, installing solar and storage means you can generate power that can help cover your energy usage, reduce your carbon footprint, and help California eliminate greenhouse gas emissions from electricity generation by 2045.
