How Does Home Solar Power Work

How Do Solar Panels Work

How do solar panels work for your home?

When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel, and multiple panels can be wired together to form a solar array. The more panels you can deploy, the more energy you can expect to generate.

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.

Can You Run 240v Of Solar Panel

Yes, it is possible to run 240V of solar panel. However, it is important to note that the total rating of your solar panel system must meet the requirements for the voltage your wiring is rated for. Typically, this means adding multiple panels in series to exceed 240V, as only very large, expensive solar panels are available in 240V ratings.

Additionally, special precautions, such as an approved AC inverter, must be taken as incorrect wiring of high voltage solar panels can be dangerous or cause permanent damage to components. Before attempting to run a 240V solar panel system, consult with a qualified electrician or professional solar contractor to ensure all wiring and components adhere to local codes and regulations.

Smart Meters And Net Metering

If your home has a smart meter, it allows you to take advantage of net metering if its available in your area. If your solar panel system is connected to the electricity grid then net metering allows you to get credits from your local utility company for any surplus electricity generation.

Your smart electric meter will record energy production in addition to consumption, and when you generate more energy than you need for your home, you can export that power to the grid and earn credits that can help reduce future electric bills.

Electrical Panel Distributes Electricity

How Do Solar Panels Work?

Your electrical panel distributes electricity throughout your home. The circuit breakers in the electrical panel can also cut off the flow of current to an electrical circuit in case a fault or surge occurs, to prevent overload in electrical lines that can cause damage.

While your solar panels generate electricity, they typically arent connected directly to your appliances or other electronic devices. In terms of understanding how do solar panels work, they provide electricity to the electrical panel, and your electrical panel separates that home solar power into individual circuits that run to everything in the house.

Lastly, electrical panels are also a key component of consumption monitoring. There are devices that can be attached to either the main panel or each individual circuit, allowing you to view more details about your specific energy consumption, which can help you optimize your energy usage over time.

What Makes A Good Roof For Solar

Here are 3 basic factors that determine whether a roof will be good for solar:

  • Space: We need a reasonable amount of unshaded space to put the system on your roof. An average 4-6 kW system will need 200-400 square feet.
  • Orientation: Roof space also needs to be oriented well to capture the maximum sunlight over the course of the year. South-facing is best, but east and west-facing roofs will work as well. We only really start to lose production when facing north.
  • Low Shading: Our design specialists conduct a shading analysis to make sure there arent too many shadows from trees. We use a tool called a Suneye that measures and calculates the available solar energy of the site by day, month, and year.

Connecting Solar To Your Home And The Grid

Each electric utility has its own solar policy for connecting your solar system to the electric grid, known as utility interconnection.

Most of the time, solar homeowners will be generating more electricity than they can use when the sun is up, so knowing how the utility compensates you for the extra power you send to the grid is critical for figuring out the economic benefit of solar for you.

How Does Solar Energy Work And How Do We Use It In Our Homes

There are no moving parts. No combustion takes place, nor is any noise generated. No space is required other than the surface of your roof. It requires no fuel, just sunlight. And despite all that, it can power your entire home and produce surplus power for you to export to your neighbors.

Yes, Im talking about solar energy. The way it works seems so remarkable and mysterious that it seems almost like magic. But solar power production is actually pretty straightforward. And, believe it or not, the solar technology used in modern solar panels has remained essentially unchanged since the 1950s.

So, how does solar energy work? What has to happen for plain ol sunlight to be converted into electricity that can power your home appliances?

This blog will answer those questions. It will also look at how solar energy works at night, and the role batteries play in solar power systems.

Solar Offers A Backup Power Source

Solar Power System For Home: Ultimate Beginners Guide

Whereas solar panels are revolutionizing and transforming how people around the world safely and efficiently power their homes, having a backup power source is always a smart idea should something go wrong and as a result, your solar power temporarily goes out. Most of the best solar companies offer some sort of back-up power source, usually a high-capacity solar battery.

Having backup energy is very important in the case of an emergency, cautions Emmer. Whole-home backup battery solutions are now available and can keep your home running for several days in the case of an emergency. Weve seen a lot of advances in this area recently and expect there to be many more to come as homeowners begin to understand that they can truly create a net-zero home and be in control of their energy needs.

Main Electric Service Panel

Solar electricity from your inverter flows to the electrical panel, and then into to your home where it powers your lights and appliances. If your panels generate more solar energy than you use, the excess power will flow into the utility grid. Even better? You might even earn extra energy credits from your local utility.

How To Install Grid

Your best bet is to go with a residential solar installation company. A solar system must be custom-designed to fit the needs and available sunlight at your home. A professional installer will know things most homeowners may not have thought of. Are you are in an area with ToU billing? Or which way should your panels be facing to get a better return on investment? Customers on high evening ToU rates should face their panels south/southwest. By facing the system south/southwest, the homeowner gets paid at peak electrical rates instead of paying peak electric rates.

How Is Solar Energy Used To Power Your Home

Most home solar systems are grid-tied meaning that the solar system, home electrical system, and local utility grid are all interconnected, typically through the main electrical service panel.

Connecting these systems means you can power your home with solar electricity during the day and grid electricity at night. It also means your solar system can push excess electricity onto the local grid to power surrounding systems, like your neighbors house.

Through net metering, you earn credit for excess solar production that can be used to offset the grid electricity you use at night.

Permits And Documents: The Logistical Paperwork Required For Your Solar Panel Installation

As with any big financial decision, installing solar panels involves a lot of paperwork. Luckily, most of this paperwork is dealt with by the installer regardless, its always a good idea to know whats going on behind the scenes of your solar installation. One of the main things youll be applying for will be state and federal solar incentives such as the federal ITC, local solar programs, clean energy financing initiatives like PACE, government rebates and solar renewable energy certificates .

In addition to applying for incentives, you will need to fill out other paperwork like building permits during the solar panel installation process. These permits are specific to where you live. For example, certain states require that a roof has three feet of clear space surrounding the solar panels, whereas other areas of the U.S. will allow you to install panels across the entire surface of your roof. Your installer will know the restrictions and requirements of the states in which they operate, and can help you figure out which permits you need in many cases, the installer will fill out this paperwork for you.

The time frame for this step is mainly dependent on how long it takes your installer to get it all finished and submitted. If youre eager to get your panel system up and running immediately, just make sure to follow up with your installer to check on the progress of your paperwork.

How Does Home Solar Power Work

  • Solar Panels

    Solar panels are made of photovoltaic cells that convert sunlight to direct current electricity . As long as rays are hitting your roof, rain or shine, your panels are converting solar radiation into DC electricity. But in order to get the kind of power needed to turn the lights on in your living room, youll need an inverter.

  • Inverter

    The inverter is a device that takes the DC electricity produced by your solar panels and turns it into alternating current electricity . Its typically installed on an exterior wall of your house, or in the garage.

  • Main Electric Service Panel

    Solar electricity from your inverter flows to the electrical panel, and then into to your home where it powers your lights and appliances. Or, if you generate more solar energy than you use, it flows into the utility grid and while you rake in the solar credits.

  • Sunrun Meter

    Your Sunrun meter monitors your system production and sends the information to Sunrun through a wireless signal. Since it tracks your energy production 24/7, it will automatically alert Sunrun if it detects problems or irregularities.

  • Net Meter

    Speaking of solar credits, the net meter measures the amount of electricity you draw from the grid, and how much excess solar electricity you push into it. So when you use less electricity than you make, you get credit from the utility company. Sounds pretty sweet, right?

    How Does A Solar Energy System Work At Night

    Solar panels need sunlight to generate electricity, but we all know that the sun doesn’t shine at night. To service your electrical loads after dark, a grid-tied solar panel system – the most common type of solar system – relies on power imported from your utility company.

    Thankfully, theres a good chance you wont have to pay for much, or any, of the electricity you import at night. This is the case if you live in a state with 1:1 net metering, which is currently 38 out of 50 states. Here, the surplus power your system exported during the day is used to cancel out the cost of your electricity imports at night.

    This video explains how a grid-tied solar system works by exporting energy during the day and importing energy at night.

    How Does Solar Power Work The Photovoltaic Effect Explained

    How Solar Power Works

    Solar panels turn sunlight into elctricity through the photovoltaic effect, which is why theyre often referred to as PV panels.

    The photovoltaic effect occurs when photons from the suns rays hit the semiconductive material in the cell of the solar module. The photons activate electrons, causing them to free themselves from the semiconductive material.

    The free electrons flow through the solar cells, down wires along the edge of the panel, and into a junction box as direct current .

    This current travels from the solar panel to an inverter, where it is changed into alternative current that can be used to power homes and buildings.

    How Do Solar Panels Work On Houses

    Solar panels work by absorbing sunlight with photovoltaic cells, usually after being placed on the roof of a house. The panels convert this sunlight into direct current energy which travels inside the house to an inverter, which in turn converts it to alternating current energy, which then flows through the homes electrical panel powering any appliances with electricity. Any excess electricity will be sent off to the electric grid, which in turn provides you with the electricity needed if you use more than the panels create.

    Thats a lot to take in all in one go, so heres your four-step overview:

  • Solar panels absorb energy from the sun and convert it into DC electricity.
  • DC electricity from your solar panels is converted to AC electricity by inverter technology .
  • Electricity flows through your home, powering electronic appliances and devices.
  • Any extra electricity produced by the solar panels is fed back to the electric grid.
  • When Exposed To Direct Sunlight A Typical Home Solar Panel Produces About 300 Watts In One Hour Which Means That In A Normal Day During Summer It Can Produce Around 3 Kwh Of Energy

    • It requires the adequate number of solar panels to absorb as much solar energy as possible. When exposed to direct sunlight a typical home solar panel produces about 300 watts in one hour which means that in a normal day during summer, comprising 10 hours of sunlight, it can produce around 3000 watts or 3 kWh per day. This could vary depending on the number of hours of sunshine received during the day.
    • The system requires a battery which can be charged by the solar power generated and also can store electric power to be used in the night. Batteries are typically used in off-grid systems.
    • The system needs an inverter to convert the DC power generated to AC power so that it can be used by the appliances or devices in the home.
    • The entire home solar power system is interconnected with adequate and appropriate cabling and wiring to channelize the energy into a usable form.
