Introduction to solar

What are solar panels?

What are solar panels? Solar panels, also called solar modules, are devices that are used to capture and convert sunlight into electricity. They are made up of photovoltaic cells, which are made of silicon and other materials that are able to absorb sunlight and turn it into electricity. Solar panels are typically mounted on rooftops or on the ground and used to power homes and businesses.

How do solar panels work?

Solar panels are a revolutionary technology that harnesses the power of the sun to generate electricity. But how exactly do they work?

Solar panels are made up of solar cells, which are essentially tiny devices sensitive to light, most commonly made from layers of silicon and other materials. When sunlight hits the cells, it excites the electrons within them, causing them to move around and generate an electric current. This current is then channeled through wires and into a solar inverter, which converts the direct current (DC) electricity into alternating current (AC) electricity, which is the type of electricity that we use in our homes.

Solar modules are connected in a series called a solar array, which allows the energy to be generated at a higher voltage. This higher voltage makes it easier to transmit power over long distances, such as from the roof of a house to a utility grid.

Benefits of solar energy

Now, let’s explore just a few of the many benefits that solar panels can provide to homeowners.

Solar panels reduce electricity costs

Installing solar on a home can be a significant investment, but it can also result in substantial savings on electricity bills.

When we talk about solar savings, we refer to the amount of money you would have paid for electricity if you did not have solar panels installed on your home. This avoided cost is calculated by determining your average energy usage, measured in kilowatt-hours (kWh). In the United States, a residential utility customer's average annual consumption is 10,715 kWh per year or about 892 kWh per month. When you multiply this number by the national average electricity rate of $0.14 per kWh, the typical American family has a monthly electric bill of around $125. If you had enough solar panels installed to cover your electricity usage, you could save almost $1,500 per year on your electric bills.

In the United States, people who switch to solar energy typically save around $37,500 over 25 years. However, the amount of money that an individual can save by using solar energy can vary significantly, depending on factors such as the size of their roof, how much sunlight it receives, the cost of electricity in their area, and any solar incentives or discounts that are offered for using solar. Solar savings can range from $10,000 to $90,000.

Solar power helps the environment

Installing solar panels on your home can greatly impact the environment. Solar systems use the sun's energy to produce electricity, making them a clean, renewable energy source. This means that by using solar, homeowners can help reduce their carbon footprint and decrease their reliance on fossil fuels. Basically, each kilowatt of solar you install will cut your home's carbon emissions by 3,000 pounds per year. So if you have a typical 5-kilowatt solar system, that's a reduction of 15,000 pounds of CO2 annually. You probably won't be able to eliminate your home's greenhouse gas emissions totally, but solar panels can definitely help you significantly reduce your carbon footprint.

Not only do solar systems reduce carbon emissions, but they also help to reduce air pollution. Solar systems do not produce any greenhouse gases or harmful pollutants, so they can help to improve the air quality in your community. This is especially important for people who live in areas with high levels of air pollution, as it can have serious health consequences.

PV panels give you independence from the grid

One of the biggest advantages of using solar panels is that it allows homeowners to be independent of the utility. This means that homeowners can generate electricity using the sun's energy instead of relying on the power company for their energy needs. This independence can be critical in areas where the power lines are unreliable or prone to outages, as homeowners with solar panels will still have access to solar electricity even when the grid goes down.

Choosing the right solar system

Choosing the right solar system for your home can be a daunting task, but with a little bit of research and knowledge, the process becomes much more manageable. In this section, we’ll go over the main things to consider when picking out a solar system for electricity generation.

Factors to consider when selecting solar panels

• Capacity: The capacity of a solar panel refers to the amount of energy it can generate. It is important to select solar panels with a capacity that meets your energy needs.

• Efficiency: This refers to how effectively the solar panel converts sunlight into electricity. Higher-efficiency panels will produce more power and may be a more cost-effective option in the long run.

• Solar panel type: There are two main types of solar panels, monocrystalline and polycrystalline. Monocrystalline panels are made from a single crystal of silicon and tend to be more efficient, while polycrystalline modules are made from multiple crystals and tend to be less expensive.

• Durability: Solar panels should be able to withstand harsh weather conditions, such as high winds and extreme temperatures. It's important to choose solar modules that are built to last.

• Solar brand reputation: It's always a good idea to research the reputation of the solar panel manufacturer before making a purchase. Look for reviews from other solar customers and consider the company's history and track record in the industry.

• Warranty: Look for solar panels that come with a good warranty, covering both the panels and the installation. This will give you peace of mind and protect your solar investment in case of any issues.

Types of solar systems available

There are three main types of solar electricity systems. The most common type is ongrid systems that are connected to the local power lines. This means that when the solar system generates excess electricity, it is sent back to the grid for others to use. When the solar panels are not generating enough power, the system will draw it from the grid. These systems are useful for those who live in areas with a reliable energy supply and want to reduce their energy bills.

Off grid solar systems are not connected to the electric power distribution lines and instead rely on batteries to store excess energy. These systems are helpful for those who live in remote areas or who want to be completely self-sufficient. However, they can be more expensive to set up and maintain due to the need for batteries and backup generators.

Hybrid solar systems are a combination of both types. They can be connected to the grid and also have batteries for backup power. These solar electricity systems offer the benefits of both on grid and standalone systems but can also be more expensive due to the added complexity.

Overall, the type of solar system that is best for a household depends on its specific energy needs and location.

Sizing your solar panel system

When setting up solar panels, it's crucial to ensure you get the right size for your house. There are several factors that need to be considered, including your energy needs, the size and orientation of your roof or ground space, and the amount of sunlight your location receives.

To determine your energy needs, you will need to consider the amount of energy your home or business uses on a daily, monthly, and annual basis. This information can typically be found on your energy bills or by speaking with your energy provider. You will also need to consider any future energy needs, such as the addition of new appliances or an increase in the number of people living in your house.

After figuring out how much energy you need, you can use that information to determine the size of your solar system. There are online tools and software programs available that can help you with that. Alternatively, you can consult with a solar panel installation company or a solar calculator to help you determine the size of your system. Make sure you get the right size solar system to meet all your energy needs and give you the most electricity it can.

Financing your solar modules

While solar electricity systems can be a cost-effective and environmentally friendly solution for energy generation, they do come with a significant upfront cost. Therefore, it is important to consider the various financing options available for solar modules to make the transition to solar energy as smooth and affordable as possible.

Paying for solar panels outright

This solar option involves paying the total cost of the solar panel setup upfront, either through personal savings or by taking out a solar loan. The benefit of this option is that once solar panels are paid for, the homeowner does not have to pay any additional fees for energy generation. However, the upfront solar cost can be a significant barrier for many homeowners.

Solar panel leases and power purchase agreements

These financing options allow homeowners to install solar electricity systems without having to pay the upfront cost. In a solar lease, the homeowner pays a monthly fee to the solar company for the use of the panels, and the company is responsible for maintaining and repairing them. In a solar PPA, the homeowner agrees to purchase energy generated by the solar panels at a predetermined rate from the solar company. These options allow homeowners to go solar without buying the panels outright, but they may have higher monthly costs over the long term.

Solar incentives and programs

There are various solar programs and incentives available to homeowners to help make the transition to solar energy more affordable. One of the most significant incentives is the solar tax credit, which allows you to claim a credit of up to 30% of the cost of your solar system.

In addition to the solar tax credit, there are also state and local solar incentives available. These can include solar rebates, grants, and low-interest loans. These solar programs vary from state to state, so it's worth doing some research to see what's available in your area. It's also a good idea to check with your local utilities company, as they may have their own programs to encourage solar adoption.
