Is Photo voltaic Power Renewable? Suggestions for Owners

6 min read

Renewable vitality is vitality from pure sources that replenish at a better charge than we devour them. They’re an important instrument to combat climate change and may create a extra equitable world. Wind, hydropower, and geothermal vitality are examples of renewable vitality, however is photo voltaic vitality renewable? 

Whether or not you reside in a home in Columbia, MD, or an condo in Boston, learn on to find out about photo voltaic vitality, the way it compares to different vitality sources, and the way we harness it to energy our houses, cities, and the world.


Is photo voltaic vitality renewable?

Photo voltaic vitality is an infinite, renewable useful resource. It’s the cleanest and most abundant vitality supply obtainable. It’s produced by the solar’s mild and warmth, that are inexhaustible for so long as the solar exists.

Nevertheless, photo voltaic panels, one of many main strategies we use to harness vitality from the solar, usually are not a renewable useful resource. They require substitute each 25-30 years and are not entirely recyclable. Important developments are underway, akin to biodegradable biopanels, however none are extensively obtainable. 

What’s photo voltaic vitality?

The solar produces two kinds of vitality that we are able to harness: mild and warmth. It produces these via nearly-infinite nuclear fusion. The brighter and warmer an space is, the extra vitality we are able to harness from the solar. 

As well as, photo voltaic vitality doesn’t emit greenhouse gasses, making it an environmentally-friendly different to conventional vitality sources. It’s additionally extraordinarily cost-effective and will help householders and companies save money on their vitality payments over time.

How does solar energy work?

There are three main methods to harness solar energy: photo voltaic panels, concentrated photo voltaic, and photo voltaic course of warmth. 

  • Photo voltaic panels: Photo voltaic panels are the most typical sort of photo voltaic expertise for householders and companies. If in case you have photo voltaic panels, you should utilize the electrical energy they generate such as you would some other energy supply. Electrical energy from solar energy can warmth and funky your property, warmth water, energy lights and home equipment, and extra. 
  • Concentrated photo voltaic: Concentrated photo voltaic expertise is primarily utilized in large-scale photo voltaic farms and industrial use. Firms additionally usually construct photo voltaic farms in areas that obtain loads of daylight. For instance, the largest solar farm within the US is situated simply exterior of Los Angeles, an space that receives an enormous quantity of daylight yearly. 
  • Photo voltaic course of warmth: Solar process heat is a technique of utilizing photo voltaic vitality to warmth, cool, and ventilate an area, in addition to change conventional water heaters.

How is photo voltaic vitality completely different from different vitality sources?

Solar energy is extra renewable and sometimes extra ecologically pleasant than different frequent vitality sources, together with fossil fuels, nuclear energy, hydropower, and wind energy. Let’s dive in to find how. 

Fossil fuels

Fossil fuels are finite and can finally run out, which implies they aren’t renewable. Additionally, they emit dangerous gasses like carbon dioxide and methane and require tons of vitality to extract. 

Pure gasoline is far cleaner than different fossil fuels, however nonetheless emits methane and sometimes requires fracking to extract. Additionally it is very liable to leaking throughout transportation and whereas in storage. 

Nuclear energy

Nuclear energy is not a renewable energy source, nevertheless it doesn’t emit greenhouse gasses. Nevertheless, nuclear energy vegetation produce huge quantities of extremely poisonous, harmful radioactive waste. Society hasn’t found a way to securely retailer or eliminate nuclear waste in a method that doesn’t leak and considerably hurt folks and the surroundings. 

Moreover, nuclear energy vegetation can explode, inflicting widespread and decades-long destruction.


Hydropower is a really clear vitality supply and doesn’t emit any greenhouse gasses. Nevertheless, dams devastate salmon populations together with many different species of vegetation and animals. And as local weather change worsens, many reservoirs and rivers have dried up, inflicting severe concern about the way forward for hydropower.

Wind energy

Like photo voltaic, wind energy is an infinitely renewable useful resource with much less environmental impression than different vitality sources like fossil fuels and hydropower. 

In comparison with solar energy, wind energy isn’t as extensively obtainable or constant as solar energy. And, some areas will not be windy sufficient to generate the kinetic vitality wanted to energy a house or group of buildings. 

Whereas residential wind turbines can be found (small wind electrical techniques), they usually require extra particular circumstances than photo voltaic panels and will not generate as a lot electrical energy. Plus, they require particular zoning permits and are costly to put in. 

Photo voltaic vitality for householders

Photo voltaic vitality is a inexperienced different to conventional vitality sources and helps the surroundings. In case you are interested by harnessing solar energy, many applications on the state and federal ranges will help you get monetary savings in case you set up photo voltaic panels. Additionally, you might be eligible for a tax credit score in case you swap to solar energy. 

Advantages of photo voltaic vitality for householders

Capturing photo voltaic vitality will help you save money and scale back your carbon footprint. 

Photo voltaic panels could be costly upfront, however can prevent cash in the long term by lowering or eliminating the electrical energy prices in your house. Additionally, costs of photo voltaic panels are going down as they develop into extra obtainable. Plus, you might get a tax credit score or different profit by going photo voltaic, relying on the place you reside. Lowering the quantity of hydropower, pure gasoline, and different vitality sources your property makes use of may even reduce your carbon footprint and environmental impression.

How photo voltaic vitality helps the surroundings

Photo voltaic vitality is renewable and doesn’t emit dangerous greenhouse gasses or noxious chemical compounds. Whereas different vitality sources might dry up, like hydropower and fossil fuels, solar energy gained’t. 

Nevertheless, there are some downsides to photo voltaic vitality. For instance, photo voltaic farms take up loads of house and may negatively affect biodiversity, birds, and pollinators in the event that they aren’t deliberate fastidiously. 

It additionally takes different pure sources moreover daylight and house to fabricate photo voltaic panels. Many sources go into making photo voltaic panels, akin to silicon and water, that are utilized in manufacturing and manufacturing.


Ultimate ideas on photo voltaic vitality 

As local weather change persists, it’s important to take a position extra in renewable vitality like solar energy. Photo voltaic vitality is a virtually infinite vitality supply and is way cleaner than fossil fuels, akin to pure gasoline and oil. 

Owners can harness photo voltaic vitality through the use of photo voltaic panels. Photo voltaic panels convert vitality from the solar into electrical energy, which you should utilize like some other type of electrical energy. Whereas photo voltaic panels themselves aren’t fully renewable, they assist the surroundings whereas reducing your vitality prices. 

Redfin doesn’t present monetary or environmental recommendation. Particular person vitality wants, use, and capabilities might differ. All the time seek the advice of an expert and take your particular person circumstances under consideration earlier than putting in photo voltaic panels.
