How do solar panels work?
Solar panels work by converting sunlight into electrical energy. The sunlight hits the solar panel and the panel converts the light into electrons. The electrons flow through a circuit and create electrical current.
The cells in a solar panel are made of silicon, which is a semiconductor. When sunlight hits the cell, some of the photons are absorbed and create an electric current.
That’s why it’s important to choose a south-facing location for your solar panels, so they can get as much sun as possible.
The amount of power that a solar panel can generate depends on how sunny it is outside. On a bright, sunny day, a solar panel will generate more power than on a cloudy day. However, even on a cloudy day, there’s still some light that can be converted into electricity so you won’t be left in the dark!
In order for solar panels to work during a blackout, they need to be paired with battery storage. This way, you’ll still have access to power even when the grid is down.
Planning your home solar panel system
When planning your home solar panel system, you need to consider how much energy you use and when you use it. You also need to decide what type of solar panel system you want and how many panels you will need. You will also need to find a qualified installer and get the proper permits.
Installing solar panels on your home is a big decision that should not be taken lightly. It’s important to do your research and figure out what option is best for you.
There are two types of solar panels installation: those that are installed on your roof and those that are installed in your yard. Homeowners who have a lot of sun exposure are good candidates for solar panels and can save money on their energy bill.
The cost of a solar panel system can be an attainable upgrade for most income levels, especially if you have the property to install it yourself. The upfront costs of solar panel installation are high, but it is usually worth the investment. In most cases, your home solar panel system will pay for itself in seven to ten years.
Make sure you pick a product with a good warranty so you know your investment will last. Solar panels come with both performance warranties and product warranties. A performance warranty guarantees at least 90% production at year 25, while a product warranty guarantees 97% production from 1 year to 25 years.
1. Determine your solar potential
The National Renewable Energy Laboratory (NREL) has a great online tool that can help. You’ll need to provide some information about your home, like its location and the size of its roof.
A small system might be enough for your needs, but if you want to go off-grid or sell excess energy back to the grid, you’ll need a larger system.
2. Compare your solar options: rooftop vs. community solar
There are two main types of home-based, grid-tied solar systems that can produce electricity for you to use in your home. These are rooftop solar systems, and community or shared solar projects.
A rooftop system is installed on a customer’s roof where it generates electricity for the household to use in their own home. These systems are typically owned by the homeowner and can be financed, leased or purchased outright depending on your needs and preferences.
Community solar projects allow you to purchase a portion of a shared solar system that is built by a solar developer in your community. The energy produced by the panels belongs to you and is delivered through your utility bill, just like with any other source of electricity generation.
Where to find solar panels for your home
Solar panels can be found at a variety of places, including home improvement stores, online retailers, and through solar installation companies. It is important to compare the prices and features of various panels before making a purchase to ensure that you are getting the best deal and the right panel for your needs.
You can go through a solar panel installer, or you can buy them yourself and have a professional install them. If you’re buying the panels yourself, make sure to find a reputable company with high-quality products.
When looking for solar panels, there are a few things to consider:
The size of the system:
How many panels do you need? You’ll need to determine how much power you want your panels to generate. The amount of space available on the roof will also be a factor in this decision.
The type of panel:
There are three types of solar panels: monocrystalline, polycrystalline and thin film. Monocrystalline is the most efficient type of panel, but it’s also more expensive. Polycrystalline is cheaper than monocrystalline, but not as efficient. Thin film panels are the least expensive and most abundant on the market today.
Not all solar panels are created equal; some brands are better than others. Solar panels are rated in watts, and the higher the wattage per panel, the more power it will produce. A solar panel with a rating of 250 watts is better than one with a rating of 200 watts.
Solar panels often come with warranties of 25 years or more; make sure to check what’s included in the warranty before you buy.
What are the different types of solar panels?
There are three types of solar panels: monocrystalline, polycrystalline, and thin-film.
- Monocrystalline solar panels are made from a single, pure crystal of silicon. They’re the most expensive to produce but also have the highest efficiency levels.
- Polycrystalline solar panels are made from many small crystals of silicon, which makes them less efficient than monocrystalline solar panels but more affordable.
- Thin-film solar panels can be made from many different materials that are ultra thin in order to increase efficiency and affordability. They’re lightweight, flexible, and portable, but aren’t as efficient as other types of solar panels.
How to choose the best solar panel for your home
When it comes to solar panels, there are a lot of things to consider. How efficient they are, what type you should get, and how much they’ll cost are all important factors. Here are some questions you can ask about when choosing the best solar panel for your home:
What are your energy needs?
Not every solar panel is right for every situation. Some panels are designed for high-energy needs, while others are more suited for low-energy applications.
What is your roofing material?
If you have a dark-colored roof, then black or blue solar panels will be the best choice to maximize energy absorption. If you have a light-colored roof, then solar panels in shades of gray or brown will be more efficient at reflecting sunlight.
Crystalline solar panels are more efficient and produce more power than thin-film solar panels. They also tend to last longer and are less likely to suffer from degradation over time.
How much sunlight does your location get?
If you live in a sunny area, then you’ll want to choose a solar panel that is designed to work well in direct sunlight. If you live in a more shady area, then you’ll want to choose a solar panel that is designed to work well in less-than-direct sunlight.
What financial tax credit incentives are available in my area?
The amount of the credit and the specific qualifications vary by state. Some credits are also available at the federal level. It’s important to research what incentives are available in your area before you install solar panels on your home. You may be able to get a significant discount on the cost of your solar panels by taking advantage of these tax credits.
How long will you live in your home?
If you plan on living in your home for less than 10 years, it may be more cost effective to rent or lease a solar panel system rather than purchasing one.
If you plan on living in your home for more than 10 years, it’s likely that purchasing a solar panel system will be more cost effective in the long run.
Additionally, if you are interested in installing a solar panel system but don’t have the necessary funds, there are financing options available that can make the process more affordable.
What do residential solar panel systems typically cost?
Residential solar panel systems typically cost between $10,000 and $30,000, depending on the size and complexity of the system.
The total price depends on the size of the system, the type of panels, and the state in which you live.
Typically a 10 kW system will cost around $27,600 before tax credits and rebates, and $20,474 or less after rebates and incentives. Keep in mind that these prices vary depending on the state you live in and the size of the system – grid-tied solar panels are usually cheaper than off-grid systems.
