Solar energy is becoming more popular and this is the ideal opportunity to know more. You’re in the right place to find out more about solar energy.
This guide will provide everything you need about this amazing energy source. It will cover the basics of solar energy as well as where you can investigate and learn about the solar power source, as well as what companies are the best to purchase solar panels.
What is solar energy?
The sun’s rays emit the energy of light and heat, referred to as solar energy.
The sun’s energy is what makes it possible for life to exist on Earth. The sun’s light and warmth provide a conducive climate for living. It is vital for all living things to survive such as animals, plants, and humans.
We have been relying on sunlight for energy since the beginning of time, modern technology in solar energy has enabled us to harness this energy to produce solar heat and electricity. It is quickly becoming a cost-effective and practical source of renewable energy which means it could be a major factor in our urgent quest to eliminate our dependence on climate-degrading fossil fuels.
To fully comprehend this source of energy There are some technical terms that you should be aware of.
Everything that has to do with the sun. Sun is the main star in our solar energy systems, and it provides all the light and warmth we need on Earth.
Solar energy This broad term is used to describe the energy generated by sunlight and released in the form of electromagnetic radiation. sunlight.
Solar power: The sun’s energy, which humans have converted into electricity or heat. Sometimes, the terms “solar energy” and “solar power”, are interchangeable.
Solar electricity: This is electricity produced by sunlight. It can be created using either technological advancements in solar energy or photovoltaic.
Solar thermal: Get energy from the sun. Solar thermal energy can be used to generate energy to store solar energy for heating, as well as the generation of electricity.
Photovoltaics is the method of making electricity by utilizing sunlight on solar panels. These panels are made of solar cells that contain special semiconductor materials.
Why is solar energy so beneficial for energy from renewable sources?
Because it is impossible to utilize all of the sun’s energy, it is considered to be a renewable source of energy. The sun’s continuous solar radiation will replenish the amount of sunlight, no matter how much we capture.
We won’t be able to get enough sunlight anytime soon neither. NASA forecasts that our sun’s going to be shining for at least 5 billion more years.
These are some of the main benefits of using solar energy to meet our energy demands.
Solar energy is clean: Solar is very environmentally-friendly. Solar energy is free of pollutants and waste products.
It’s abundant: There’s an enormous amount of solar energy that hits the Earth at any time - it is more than any other source of energy.
It’s cheap: Thanks to advancements in technology, solar power has been deemed the most cost-effective source of electricity ever according to the International Energy Agency.
It’s also extremely versatile. Since solar energy is derived from sunlight, it can be generated practically anywhere. Therefore, it is possible to utilize it in a myriad of different applications, such as smartphones, handheld devices, solar rooftop systems for energy, utilities-scale plant interplanetary spacecraft and even power stations that are interplanetary!
This unique combination makes solar energy an option for renewable energy for those who want to move away from fossil fuels.
What are the different ways to generate solar energy?
Three major methods are employed to harness solar energy to make it usable:
- Solar panels that harness solar energy technologies.
- Concentrated solar power (CSP) is also referred to as solar thermal one of the forms of solar energy.
- Another type of solar thermal energy is solar water heating.
3. Solar water heating (also referred to as solar thermal)
Another way to harness sunlight’s thermal power is to use Solar water heaters. Rooftop solar thermal systems, that are not to be confused with PV solar panels, can be used to heat water inside an enclosed container.
Even in the coldest weather outside solar hot water systems can supply hot water to the majority of homes.
There are three kinds of solar power projects that are commonly used.
Solar energy can be classified into three types for classification purposes three types: residential, commercial and utility-scale.
Residential solar: This is solar energy generated by a home’s rooftop panels. Residential solar panels are typically between 4 to 16 kW of power.
Commercial solar. Also called Commercial & Industrial (C&I), Solar, it refers to the use of solar energy for businesses, government agencies and nonprofits. Most commercial solar systems are between 10 kW to 100 kW in capacity. However, certain companies like Apple or Amazon have much larger systems after investing in large quantities of solar power capacity.
Utility-scale solar: These large solar power plants produce huge amounts of power for an electric grid. Power plants that are utility-scale are classified by the U.S. Energy Information Administration (EIA). They are power plants with a total generation capacity of 1 megawatt (MW) or more.
It is easily scalable and can be utilized to power projects that are of any size. It is able to power devices, such as calculators and watches on the smallest scale. It can also be utilized in large solar parks that use thousands or even millions of solar panel.
1. Solar panels (solar photovoltaics)
Photovoltaic cell (PV) also known as solar panels, are the most popular method to harness the power of solar energy for electricity generation. It is estimated that the United States has more than 3 million solar panels. The amount of solar panels installed within the U.S. is increasing rapidly.
A set of semiconducting solar panels is made up of semiconducting cells that transform sunlight’s photons to direct current (DC). The DC power is usually fed into an solar converter, and it’s converted to alternating-current (AC) which is the type of electricity that is used in homes as well as in grids.
They can also be erected in any location you need to meet your power needs.
2. Solar power that is concentrated (solar Thermal)
Concentrated solar power (CSP) is a technique which uses special reflectors to produce electricity at the large size, is known as concentrated solar power.
CSP plants use thousands upon thousands of mirrors, called horoscopes, to reflect sunlight onto the solar thermal collectors. The sun’s heat will be kept in the form of molten salt or used to create electricity using a steam turbine.
CSP is a power plant, in contrast to PV plants, which generate power by capturing the heat of sunlight. These plants can also be referred to as solar thermal or CSP plants. Because of their tall towers CSP plants are commonly referred to as “power towers” or “salt-tank plant”.
It’s not practical to make use of CSP technology at the commercial or residential level. It’s an exciting technology for the utility scale, as it can be used to conserve energy.
Are solar cells a good idea? How do they work?
Specialized products are designed to store solar power. These solar battery stores solar power efficiently at the time it is produced , and release it when it is required.
Here’s how they work for most homes:
Solar panels produce energy and any energy that isn’t used immediately is transferred to the battery for storage. The battery can then discharge the stored power to run your appliances in the future regardless of when the panels stop producing electricity. In the event of blackouts, a solar battery can be used to supply backup power.
What is the cost for solar energy systems?
Here’s the estimated price it will cost to purchase an energy system that is solar by 2022.
Solar panels for homes range from $16,500 to $20,100 assuming a 6-kW system capacity of 6 watts with an average cost between $2.75 up to $3.35 per Watt.
An average commercial solar panel system costs $82,000. It is the 50 kW system costing $1.64 for each Watt.
An utility-scale system can cost between $850,000 and $1.01million in the event of a one Megawatt (MW) plant, with an the average cost of $0.85-1.01 per Watt.
These prices reflect the initial purchase cost before any incentives are added. They are likely to be significantly decreased by the federal solar credit that will be available in 2022. This is effectively the equivalent of a discount of 26. There are additional incentives and rebates that are available at the state, local, and utility levels.
What is the cost for buying usable solar energy?
The price of buying usable solar energy will be contingent on the amount you’re purchasing and the location from which you’re purchasing it.
The cheapest way to use the sun’s energy source is to buy solar panels that you could build yourself. In calculating the Levelized Cost of Energy is a good way to determine whether this is true.
You can buy solar power through a utility green power program, or, if it is possible, a solar community program if you are unable to set up solar panels. The former will be slightly more expensive than regular utility electricity, but the latter is smaller.
Below are three possible options:
Low cost energy (LCOE for solar panels that are installed at your home): This is the cost per kilowatt hour (kWh) that permits you to compare solar power generation costs against the cost of electricity that you get from your utility.
The LCOE is determined by dividing your system’s installation costs by the anticipated energy production over the system’s lifespan generally 25 years. The LCOE for a home solar system usually falls between $0.08 and $0.11 per kWh, after applying incentives.
Sometimes, it may be lower. This is significantly lower than what consumers pay for their utility energy.
Your utility will sell you green power: A green power plan promises that a portion of your energy supply, usually 50% or more is generated by renewable sources such as solar.
It’s usually an increase of 10% in your utility’s standard electricity rates. If you pay $0.20/kWh in electricity costs, purchasing green power from your utility might cost you $0.22/kWh.
A green power plan can result in a monthly increase of $150 in your electric bill to $165. Green power prices can vary from one utility to another therefore, you should inquire with your provider about the details.
Participate in a community program to obtain solar energy. These programs provide you with the chance to be part in large-scale solar projects , and also receive an encapsulated portion of the benefits.
It is typical to pay a monthly fee to subscribe and the owner of a solar farm owned by a community will award you a portion of solar power produced. Through a process known as”virtual net Metering”, the utility will reimburse you by lowering the average monthly electric bill.
A monthly fee of $50 to a solar company that is a community service could lead to your utility bill dropping by 60 percent. This would translate into a $10 monthly savings.
Are you thinking of installing solar panels on your house?
A solar estimate is the ideal way to begin when you’re thinking about going solar. You will get all the data you need to decide if going solar is a good option. The information includes how big the system, the cost, and the savings you can expect.
