Solar energy is sustainable. Some compelling reasons include that it is renewable, does not pollute the environment during operation, and reduces dependence on the grid. In the first quarter of 2024, solar accounted for about 75% of the global renewable energy capacity added to the grid. The International Energy Agency reports that solar power represented about 5.4% of renewable energy in 2023 and is expected to double by 2028.

Solar Panels are Recyclable

There are two types of economies, namely linear and circular. In a linear economy, commodities are disposable, tailored to be discarded and replaced after their worth has been extracted. On the contrary, a circular economy offers a sustainable solution because resources are recycled back into the economy after their initial use. It creates a regenerative, resilient system that reduces environmental damage and eliminates waste. Solar panels are recyclable.

First, the solar energy experts will inspect solar panels for reuse. They will assess the panels' durability and power and review whether they can be recycled. If the panel is recyclable, the experts will remove the junction box and aluminium frame to start the recycling process. Next, the crystalline silicon modules undergo the proprietary recycling equipment to remove the glass from the solar laminate. The remaining laminate, which comprises solar cells and a back sheet, is shredded. The shredded materials are then separated from the plastics, and valuable materials, like silver, copper, and silicon, are recovered. Advanced recycling processes extract most of the value of old panels, returning the materials into supply chains.

Solar Energy is Renewable

Solar energy is a clean, abundant, renewable resource that will never run out or be in short supply.

Photovoltaics is the process of harnessing solar energy with solar panels to generate electricity. The solar panels have photovoltaic cells that absorb sunlight and convert it into direct-current electricity. The inverter converts the electricity into alternating current electricity that you can feed into the grid or use in your home. To use solar power, you should install your panels on the roof or anywhere where they are angled towards the sun.

As long as the sun shines, solar power through the photovoltaic effect is possible. It makes it the most infinite, renewable source of energy available to man.

Everywhere Gets Sunlight

The fact that every area of the earth receives sunlight to a lesser or greater extent, even to regions with no connections or infrastructure.

Shining on from above, you can use solar energy on a hyperlocal scale, including for your consumption. If you look at solar panels installed on the roof, it is apparent that this is not the case with most renewable resources.

After the panels generate electricity, it is effortless to transport solar energy. That means you can generate huge amounts of electricity in a large solar farm.

Solar Energy Creates Jobs

Solar energy creates many employment opportunities for installers, builders, maintenance technicians, and developers at power plants. Going solar provides new impetus to the economy and offers businesses, nations, and families opportunities.

Solar Panels are Cost-Effective Over Time

If you are considering going solar due to its financial benefits, you might be wondering whether the panels will save you money. Will the panels make a considerable dent in your house utility bills? Will your investment balance out with maintenance and installation costs?

Although the answer to the above questions varies for every home, a solar installation should save your home money over time. It means having a system tailored to your house, taking into account the roof's direction, shape, and size, as well as your house's energy consumption.

Some of the ways you can boost your savings by going solar include the following:

Federal Tax Credit

The federal government offers incentives for homeowners to go solar. The federal tax credit allows homeowners to claim a 30% tax credit for all solar-related costs. It means that if you are eligible, your tax bill will be reduced based on the percentage of the cost of your installed solar system.

California does not offer net metering. However, if you are a client of San Diego Gas and Electric, Southern California Edison, or Investor-Owned Utilities, Pacific Gas and Electric, and you have connected the solar system to the grid, you can benefit from net billing.

Net billing is identical to net metering in that you earn credits when you send your surplus electricity to the grid. When the panels are not generating a lot of electricity, and you want to pull electricity from the grid, the utility will apply the credits to your bill.

The net billing contributes to a shorter payback period and boosts savings. However, it is less valuable for solar owners than net metering. To maximize your savings, consider adjusting your consumption habits and installing solar batteries to store surplus energy rather than relying on the utility.

Disadvantaged Communities' Single-Family Solar Homes

The program is an incentive available to individuals who own homes and live in disadvantaged communities served by California's largest electric utility companies.

The program offers incentive payments that can be integrated with other local incentives to cover the cost of rooftop panels for the residents. The nonprofit GRID Alternatives administers the program.

Solar Panels are Durable

Your solar panels' lifespan is not determined by when they stop generating electricity. Instead, homeowners and experts will use the panel’s useful life to determine its lifespan. Lifespan is approximately twenty-five to thirty years.

Panels gradually degrade and generate less electricity with time. An older solar panel can be beneficial for a tiny application with low energy demand, but many homeowners retire solar systems after approximately thirty years. By then, energy generation has significantly declined, making it sensible to replace the panels with a new, higher-performing system.

Research conducted by the National Laboratory of the Rockies, which analyzed data through 2022, found that solar units experience a performance loss of about 0.75 percent annually. The decline rate is known as the degradation rate.

Your solar panel's degradation rate can indicate how much energy you can expect the unit to generate in a given year of its useful life.

A Warranty can Ensure the Solar Panel will Last its Life

Solar system warranties maximize the lifespan of a solar panel. In addition to the equipment warranty, which covers manufacturing defects, the performance warranty ensures that the panels will maintain a specified percentage of their output annually. It can help you understand the panel’s expected degradation rate.

Many solar batteries have a ten-year warranty. You should consider looking out for through-clauses or cycles that can reduce the warranty duration if you frequently discharge the battery several times a day.

How to Maximize the Panels

Generally, solar units are durable and designed to withstand harsh weather conditions such as strong winds, hail, and snow loads. Although the system requires minimal maintenance, keeping the panel in good condition can boost energy generation.

Here are some things you can do to maximize the panels:

  • Protect the panel from damage — Provided your panel does not sustain physical damage, it should generate electricity for years. You can trim or cut down surrounding trees to prevent branches from falling on the panels. You can also clear debris and use specialty equipment to prevent physical damage to the panels. For instance, a critter guard could keep animals away from the panel, which could prevent wire and panel damage.
  • Inspect your panel regularly—Conducting regular maintenance checks can expose problems, including loose racking and exposed wires. You also want to ensure the inverter is functional. Depending primarily on the form of your inverter, you can repair it halfway through the panel’s useful life. It is advisable to consult with an expert to inspect your panel. Damaging or scratching the panels can void the warranty.

Installing Solar Panels Increases a Home's Value

According to a study conducted by Zillow, installing a solar system increases your home value by $5,911 for every kilowatt of solar panel installed, and another estimate shows an increase of 4.1% of the house’s value.

While these figures give you a ballpark, different factors influence the value solar panels add, including the following:

  • Geographic locations—Location can influence the amount of sun exposure you receive and the social benefits of going solar.
  • Local solar installation prices—If a person were to save funds by buying your home with an installed solar system, it would make your house more valuable.
  • Solar system age—An older system will not add much value to your house when selling it, because the buyer will likely need to replace or repair the parts.
  • Panel’s replacement value—How much more difficult and expensive it is to replace the different parts of the solar panel affects the value of your home.
  • System output — The larger your solar system, the more energy it generates and the more added value.

Solar Energy Reduces Carbon Footprint

Solar systems have a lower environmental impact, eliminating emissions due to burning and harvesting fossil fuels. The photovoltaic effect does not depend on resources that require mining or extraction and subsequent transport to power plants.

Additionally, generating energy in a photovoltaic system does not require combustion, which produces carbon dioxide emissions. Solar panels generate clean, renewable energy.

Sourcing raw materials for photovoltaic cells, shipping panels, and manufacturing them creates emissions associated with panels. However, the operation pays down the debt quickly, and most solar systems become carbon-negative within three years of going solar.

Cutting emissions and reducing greenhouse gas emissions have a significant impact on your carbon footprint.

Solar Systems Work in all Weather Conditions

Your solar panel will work on cloudy days, but it will not be as effective as on a sunny day. It will produce appropriately ten to twenty-five percent of its power output, depending on the thickness of the cloud cover.

Here is a twist: the solar system does not work effectively in hot climates. The output starts to decline if the panel's surface temperature exceeds 77 degrees Fahrenheit. That said, a solar unit can work and be worth it across different climates.

Solar panels do not generate energy at night because they require sunlight to produce electricity. While they can generate electricity from other light sources, like the moon, the output is low.

You can store your solar energy.

While you can store your solar energy via thermal or mechanical storage, these options require a lot of materials, moving parts, and space. Solar batteries are the most practical way to store your residential solar electricity.

When you want electricity from your solar battery, the electrons flow back and electricity is discharged from your batteries. The process is repeated, making the solar batteries rechargeable.

Weighing the Advantages and Disadvantages of Going Solar to Determine whether It is Sustainable

One disadvantage of going solar is that you might have a roof ideal for your solar system, but still not be eligible for solar energy. To maximize the system's benefits, you need a yard or roof that receives direct, consistent sunlight.

Another con is that the system array takes up a lot of space. What most people do not consider when going solar is that not every roof can support an array large enough to cover the installation cost.

So do the pros of going solar outweigh the cons? Answering this question is not easy, since individuals may experience varying levels of savings.

Before installing the system, ensure you do your due diligence. Research extensively about your local sun exposure, your household energy bills, tax incentives, and how much a new solar system will cost you. Weighing the different cons and pros will help you determine whether going solar is sustainable and make an informed decision for your household.
