Solar energy pros and cons in 2021

There is a lot of useful solar energy information out there and sadly, lots of harmful misinformation too. In this post, we are going to cover some the main advantages and disadvantages of installing solar panels and the industry as a whole. The advantages of solar energy spread far and wide. The benefits of solar panels have extensive implications including financial, social and of course, environmental factors. Many of these are well known, many of these are not; we will investigate each one thoroughly.

No technology is perfect, and many perceived disadvantages are just solar myths. We will take an in-depth look at what real, and more importantly, what is being done to improve the technology. Yes, they are factors which affect the overall system but there are mitigation strategies to this. Net Billing means the energy retailer will monitor how much solar energy you import vs export and credit you accordingly.

If your solar power system produces more energy than you can use in the summer, you will build up a credit and draw from it during times when it is not sunny i. This is the key reason why solar energy systems are still viable even though we have long, dark winters. This is where energy storage comes into play. Economically utilizing energy storage systems aka batteries is going to be a major hurdle in the coming decade.

To combat the intermittency of the sun, we must ensure that we can store excess energy while we have it, and draw from it when we need it most. Battery technology is already being implemented on a utility-scale, with entire islands being powered by solar energy and potentially a significant portion of Australia being powered by solar too. Although intermittency is a factor that affects the energy generation of solar panels, there are policies and technologies that eliminate the primary risks.

This is not to say it will be simple moving forward. There are many more challenges and hurdles to overcome, but it is very doable. This one is subjective, but many people feel solar panels are ugly or take away from the look of their roof. With that said, solar panels have improved significantly in the aesthetic department in the last couple years.

Now you can get all black solar panels with black back-sheets and black frames to seamlessly blend in with darker shingles. Additionally, new electrical technologies allow more aesthetic improvements when installing solar panels.

Cabling no longer needs to be visible creating a much cleaner finish. Similarly, racking technology provides numerous color and stand-off height from your roof plane options too. Low-profile racking is quickly becoming more available, and solar panels will soon blend into the roof itself. No additional solar panels are required since the shingle itself is photovoltaic. This technology is expected to reach market in 1 to 3 years, although some similar products are out now.

The cost of solar panels is a major issue and is certainly a disadvantage for many people. But when you consider the long-term economics of solar power , it is clear that they are a better option in the end. Installing solar panels on your home is one of the few upgrades that will not only add value to your home, but it is an appreciating asset, meaning it will continually make you money.

The investment will pay for itself, and eventually earn you money. Not many other home upgrades will do the same. If you are building a new home or property, then financing the system with your mortgage is a very easy option to capitalize on the advantages of solar energy without the upfront cost. The project can be optimized during the design stage through simple recommendations from your solar contractor, and installed during the construction stage for a highly cost-effective solution.

This can entail running an empty conduit from your electrical room to the attic, or a solar installer can rough-in suitable cables and devices for you.

As the industry develops further, the cost of solar materials will continue to drop from new technological innovation, and increased competition. Government incentives are already playing a major role in reducing the investment required to install solar in Alberta, Saskatchewan, NWT, BC, Ontario and more.

Alberta offers many different solar power grants. Additionally, there is a commercial tax incentive to help businesses reduce their cost of solar power by depreciating the asset at a higher rate than normal. You can read the complete guide to solar power rebates in Canada to learn more on what is available in your area.

In short, the cost of installing solar power is factor for many people but the long-term economics make sense. The industry and governments are also actively working to make solar panels more affordable for everyone. These are the biggest issues that we commonly see and hear about from clients and the public. There are many disadvantages of solar but there are equally as many ways to innovate and improve the technology. Solar panels produce 5x to 10x less carbon emissions per unit of energy relative to coal or natural gas.

This is huge. If we as a society are to combat climate change and mitigate the effects, then we need to reduce our C02 emissions. Installing solar panels is just one way we can be better in this area. Generating electricity from coal is the most emission-intensive way to produce energy today. From the mining, through the cleaning and burning, carbon dioxide is released at catastrophic rates.

The environmental advantages and disadvantages of solar power are more widespread than we will discuss here but certainly play a major role. The cost of solar panels is a disadvantage, but the economics of solar energy is certainly an advantage.

For example, if your solar energy system is paid off in 15 years and the modules and inverters are warrantied for 25 years, then you are going to have 10 full years of profits. Solar power systems are expected to last longer than 25 years, although component replacement may be required as such a point.

The US Department of energy cited in their U. Energy and Employment Report that the coal industry currently employs , people, whereas the solar industry currently employs , people. Such exact data is not as readily available for Canada, but given our similar ratio of energy productions, with USA generating Whether solar has fully overtaken coal in Canada is to be determined, but on a global scale, employment and new installed capacity in renewable energy is growing faster than any other fuel.

Since beauty is subjective, many people myself included feel that solar panels improve the look of their home. This advantage of solar power is a hidden one.

As urbanization continues to grow and spread cities, it is paramount to make efficient and effective use of the space we have. Although we are very lucky in Alberta and Canada to generally have lots of land, being efficient with our development is always a good practice.

Installing solar panels is not the only way to heed this advantage; growing a rooftop garden if you have a flat roof is another example of making efficient use of what was once unused, wasted space.

Installing a solar power system in Alberta, Saskatchewan, NWT or many places in Canada is one of the easiest ways to add property value to your home. Since the economics of the solar panels are locked in based on your initial capital investment, the intrinsic value of the array is guaranteed.

If you decide to sell your home, then the value of your solar power system can be calculated and added to your home accordingly. Granted, there are many factor to consider when selling and evaluating your home. But the long-term warranty and secured economics of solar panels will certainly help. As society grows, so does the demand on our electricity infrastructure system. This is evident by our growing cost of transmission and distribution fees. Decentralizing our power, or at least a portion of it will reduce overall demand on the energy distribution infrastructure since energy does not need to be distributed dozens or even hundreds of kilometers.

You can directly see this advantage on your power bill if you install solar panels in Alberta. By generating your own solar energy, you no longer need to import as much, and your transmission and distribution costs will be reduced as well as your energy charge.

The final advantage of ethos is a culmination of all the other advantages as well as the overall impact of solar panels. There are far more positive impacts to installing solar power than there are arguments against it. When the advantages greatly outweigh the disadvantages, the decision is the right one and should be highly encouraged.

I hope this helped you to understand a few of the lesser known advantages of solar energy. Many of these do not make the headlines but the downstream positive impacts are extremely helpful to society as a whole. Solar power is not a perfect technology as is evident by the few disadvantages described here. The key takeaway is that although there are minor imperfections, the industry has acknowledged them and is steadily working to improve and perfect all aspects of solar power systems.

As the cost of solar panels decreases, and the efficiency continues to increase, the advantages will continue to widen the gap on the ever-shrinking disadvantages of solar.

Pros and Cons of Solar Energy

Geothermal Energy is a sustainable and renewable energy source that is still largely untapped. As an environmentally-friendly resource it has the potential to meet heating, cooling and electricity demands for the future. There are many advantages of geothermal energy but also some challenges that need to be overcome in order to fully exploit this natural resource. Geothermal energy is more environmentally friendly than conventional fuel sources such as coal and other fossil fuels. In addition, the carbon footprint of a geothermal power plant is low. While there is some pollution associated with geothermal energy, this is relatively minimal when compared to fossil fuels.

Solar power is the conversion of the sun's energy into electricity. With an estimated , terawatts of solar energy continuously hitting Earth's surface 1 , there is more than enough energy to meet the world's current consumption levels of 15 terawatts per year 2. The trick, though, is collecting it. Solar energy is primarily collected in one of two ways: photovoltaic solar cells and solar thermal. A photovoltaic cell is basically a semi-conductor connected to two electrical contacts.
