Why Are Solar Panels Good

Solar Energy Slows Climate Change

Why solar power is a good solution for rural Africa

Toxic gases produced during the generation of electricity enhance the greenhouse effect, not to mention air pollution. The greenhouse effect takes place when the earths surface is warmed to high temperatures.

This is influenced by human activities. Most catastrophic events happening today are blamed on the planets warming. The use of solar energy reduces these human activities hence reducing the effects of climate change.

Powering a household or work plant with solar energy cuts down on pollution in the environment and the air.

Reduction Of Carbon Footprint

Solar energy is clean, efficient, and sustainable for your household or workplace. Carbon dioxide is produced mostly during the generation of electricity and also during consumption.

Solar panels have no emissions whatsoever hence a guarantee of no carbon footprint if you depend on the natural energy. Here is why you should care about the environment.

Enjoy Independence From The Grid

Feeling shackled to the grid? Solar panels can provide the solution. Basically, the more energy you generate, the less you need to purchase from energy companies.

While the average solar PV system wont give you complete independence , adding a solar battery or two will empower you with genuine self-sufficiency. This way you can store any unused energy for a rainy day .

If you want to avoid using the grid while youre out and about, you can even get flexible solar panels for your off-grid road trips.

The High Cost Of Solar Trash

The industrys current circular capacity is woefully unprepared for the deluge of waste that is likely to come. The financial incentive to invest in recycling has never been very strong in solar. While panels contain small amounts of valuable materials such as silver, they are mostly made of glass, an extremely low-value material. The long lifespan of solar panels also serves to disincentivize innovation in this area.

As a result, solars production boom has left its recycling infrastructure in the dust. To give you some indication, First Solar is the sole U.S. panel manufacturer we know of with an up-and-running recycling initiative, which only applies to the companys own products at a global capacity of two million panels per year. With the current capacity, it costs an estimated $20-30 to recycle one panel. Sending that same panel to a landfill would cost a mere $1-2.

The direct cost of recycling is only part of the end-of-life burden, however. Panels are delicate, bulky pieces of equipment usually installed on rooftops in the residential context. Specialized labor is required to detach and remove them, lest they shatter to smithereens before they make it onto the truck. In addition, some governments may classify solar panels as hazardous waste, due to the small amounts of heavy metals they contain. This classification carries with it a string of expensive restrictions hazardous waste can only be transported at designated times and via select routes, etc.

Simulation Configuration And Scenarios

Go Solar Now!

We are now able to simulate the impact of the implantation of solar panels in a city on the UHI. The simulations are performed on the Paris metropolitan area, with TEB, coupled with the vegetation scheme ISBA for rural areas, within the SURFEX modeling software . The simulation domain is 100 km by 100 km, with a resolution of 1 km. At such a resolution, only the main characteristics of the buildings within the blocks in the grid mesh are kept. Geometric parameters are averaged in order to conserve the surface areas , while a majority rule applies for the architectural characteristics of buildings and the use to which they are put . These urban data are provided by a database at 250 m resolution , which contains block types as well as 60 urban indicators. Some parameters needed by TEB, such as albedos, thermal characteristics or equipment within buildings, are deduced for each 1-km-by-1-km grid mesh from urban block types and from the use and age of the majority of buildings. Countryside parameters, such as land use and vegetation characteristics are deduced from the ecoclimap database at 1 km resolution . The methodology presented in Masson et al. , based on a simplified Urban Boundary Layer generator is chosen, in order to be able to perform a simulation over an entire year. The chosen year of study is 2003, because it demonstrates the impact the solar panels would have during a heat wave.

It Helps Improve Your Grid Security

The solar cells installed in your roof functioned as a small power plant that can generate enough energy for your home. As a homeowner, installing these panels can help provide your place with efficient electricity and improve your grid security as well.

Moreover, utilizing renewables can help you save money by lowering your utility bills. It can also help avoid natural or human-caused disasters due to climate change. Since much of todays energy providers can cause air pollution, then the use of solar power can be an ideal way to fight climate change and contribute to a more sustainable future.

Solar Is Cheaper Than Ever

While electricity prices continue to get more expensive, the cost of solar has continued to fall. Solar is now cheaper than ever in fact, the cost has fallen over 70% in the past decade. These low prices make solar more accessible to more homeowners than ever before.

Installing solar can be even cheaper when you take advantage of solar incentives. For example, if you install a solar system before the end of 2022, you could be eligible for the 26% federal tax credit.

This tax credit is equal to 26% of the total cost of your solar system and is applied to your income taxes. In addition to the federal tax credit, there are many other solar incentives offered locally.

Results For Energy Production And Consumption

The impacts of solar panels are discussed in terms of energy production, of course, but also impact on energy consumption and, in the next section, on the UHI and thermal comfort. At the city scale, the production by thermal solar panels is larger than by PV. This comes both from the fact that their deployment is favored for domestic buildings and from their much higher efficiency . It should nevertheless be noted that, from April to August, production by thermal solar panels saturates , so their real efficiency decreases. Over the entire year, on average for the whole city, the thermal solar panels would produce approximately 265 MJ/year/m2 of building and the PV panels 113 MJ/year/m2 of building. This would cover an equivalent of 28% of the energy consumption for domestic heating and air-conditioning.

Solar Panel Price Vs Return On Investment

Why Is Solar Energy Good

Upfront costs for solar panel installation can be a little steep, which may leave you wondering how much money you will actually save and whether your energy savings will be enough to offset your initial investment.

It is not unreasonable to think that you can cut your monthly utility bills by as much as 75% or more by switching to solar energy. Of course, the specific dollar amount will depend on where you live, the size of your home and the number of people in your household.

One way to look at it: The average household energy bill is somewhere between $100 and $200 monthly. Based on these rates, it may take about 10 years for your energy savings to cancel out the cost of solar panel installation. However, factor in savings from tax rebates and other incentives, and most solar systems pay for themselves in closer to seven or eight years.

Everything You Need To Know About Solar Energy

Why Solar Panels Are Good For The Environment

When we say solar energy, were talking about capturing the suns light and converting it to electricity through a process called the photovoltaic effect, or PV. Solar energy thats captured using PV technology can power everything from homes, businesses, cars and aircraft, to small appliances like calculators, portable power stations and more.

The sun is the single most abundant energy source in our solar system. Without it, wed be just another cold rock floating through space. But exactly how powerful is the sun? According to the U.S. National Renewable Energy Laboratories , the amount of energy from sunlight that hits the Earth in one hour could supply the worlds energy needs for an entire year! Thats pretty powerful.

Solar energy has been one of the fastest-growing sources of new energy in the world for many years now. As of 2020, the United States has a total installed solar capacity of 97.7 gigawatts . Thats enough to power nearly 17.7 million homes!* And thanks to improved technology, more affordable materials and increased customer demand, solar continues to become more affordable. For many homeowners, that means rooftop solar now makes economic sense and can provide long-term savings.

An investment in solar will pay for itself and make the overall investment more manageable.

Remember, there arent many home improvements that cost less than a solar system or receive government tax credits, let alone saving on your homes monthly costs. An investment in solar energy is worth its money more so than almost any other improvement you can make to your home.

  • Earn a Great Return on Your Investment: Solar panels shouldnt be viewed as an expense in fact, they are one of the wisest investments you can make, with returns rivalling more-traditional investments. Thanks largely to the substantial monthly energy cost savings, the average American will pay off their solar panel system within 7 or 8 years, with an average return on investment of 20 percent or more!

Increases The Value Of Your Home

How does solar energy increase the value of your home?

When you have a property, any added facility outside the basic ones available to every other house adds more value to your property. That is why it is a smart move to get your property outfitted with solar power. It gives your property an edge over others and will also give any potential tenant or buyer the encouragement to invest in it.

Studies were conducted in the United States by National Renewable Energy Laboratory on house sales. It was concluded that homes that had solar panels installed in them had a 20% more chance of being sold than those that did not have it.

It also concluded that such homeswith solar panels cost 17% higher than those that did not have it.

How Much Does A Solar Pv System Installation Cost

An average-sized residential solar power system is 5-6Kw in capacity. As per the latest official data, the average per watt cost of solar panels in the US is $3.18 . This makes a total cost of roughly $19000.

This cost includes all of the components of the system and installation done by a solar company along with the inspection and permitting charges by the government and the utility company.

How Does Solar Energy Work

Why Solar Power Is A Good Investment

When the sun shines onto a solar panel, energy from the sunlight is absorbed by PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field within the cell, causing electricity to flow.

Thats the science behind solar energy. Now for a little history.

Though humans have used solar energy to light fires and keep their homes warm since the dawn of time, we only began to understand how solar energy works in 1839, when French physicist Alexandre-Edmond Becquerel discovered the photovoltaic effect that converts sunlight into electricity. Forty-four years later, American inventor Charles Fritts developed the worlds first rooftop solar array, using selenium coating on panels to produce an electric current. But it was Albert Einstein, in 1905, who helped us understand exactly how light produces the energy that we can capture to generate electricity. The paper that Einstein wrote completely changed the way we look at light. It also won him a Nobel Prize, which we hear is pretty awesome.

Modern PV technology was pioneered in the 1950s and 1960s, when the U.S. government developed it for use in our space program. Vanguard I, the first spacecraft to utilize solar panels, was launched in 1958, and PV solar panels have been an important part of satellites and other spacefaring vehicles ever since.

Solar Is The Way Of The Future

In 2016, the majority of energy added to the US power grid was made up of renewable technologies, with thousands of jobs and high growth associated with such emerging industries. Every indication is that this pattern will continue, with 93% of the total utility-scale generating capacity added to the grid accounted for by solar, wind, and natural gas. This puts the US up to 4th in solar PV usage, still lagging behind China, Germany, and Japan, and shows that solar is the way of the future.

  • Solar Power Uses Underutilized Land: With the increasing demand for solar energy, its accessibility has likewise increased. Many countries, especially developing countries, have undeveloped rural land that is virtually unused and can be used to generate vast energy at a great value. Through such strategies, the logistics of solar panels are no longer limited to spaces more suitably occupied by other things and can aid in global development efforts.
  • Solar Power Creates Jobs and Economic Growth: Most of the money put into solar power pays for salaries and the development, maintenance, and installation of these systems. As the technology improves and expands, thousands of jobs will be created and this industry can drive a new period of industrial growth.

What Is Solar Energy

Solar energy is the energy received from the sun. When we talk about solar energy or solar power technology, it refers to the harvesting of solar power for electricity. The solar power system consists of the solar panel, the inverter , and in some cases the solar battery.

The above-mentioned components makeup the solar power system. Although in some cases, the solar battery is notincluded.

That is because the inclusion of thebattery is optional. Having it or not having it does not affect the ability togenerate and use electricity.

Its function is mainly towardsproviding power for an extended period. That is important for night-time andduring cloudy days when the solar panel cannot generate electricity.

What Happens To The Solar Panels If I Move Out

If you get solar panels installed and later decide to move home, you can’t take the panels, smart export guarantee or feed-in tariff payments with you.

Solar payments are paid to the owner of the property where the solar panels are installed, so normally when you move, the new owner will receive the payments.

While you could physically remove the panels from your old home and install them on the new one, you still wouldn’t receive payments, as the panels would be considered ‘second-hand’ and so not eligible for the scheme.

It’s also worth noting solar panel installations are tailored to each home to fit the roof and be positioned to maximise the level of sunlight they receive so it’s likely they wouldn’t perform as well if you installed them on a different home.
