Rising electricity costs and carbon dioxide emissions have given rise to a demand for renewable, clean energy.
Solar power is the most popular way to achieve energy independence. So a lot of people ask "are solar panels worth it?" and whether or not they should invest in them.
There are many benefits to installing solar energy systems your home. But there are also some potential drawbacks that you need to consider before making the investment. So before you rush out and buy a solar panel system, it's worth spending a few minutes to understand how it works.
In this article, we will discuss both the pros and cons of solar energy for your home so you can make an informed choice and decide what's best for you.
You've seen the main points at a glance for comparison. Now let's look at them in more detail.
To start with, let's look at the many advantages of solar energy in the home.
One of the benefits to installing solar panels on your home is that they can allow you to generate your own power instead of relying on the grid. This can massively reduce your electricity bill, or even eliminate it entirely!
Once you've installed solar panels, you no longer need to worry about paying an expensive monthly electric bill (and the more you currently pay, they more you can expect to save).
It's even possible to go "off grid" and become entirely self sufficient, providing your system is large enough and you can store your excess energy. But even if you can't disconnect entirely, the long term cost savings are likely to be very significant for many people.
Statistics show that most greenhouse gas emissions are caused by the energy sector, and electricity generated by natural gas and coal fired power stations has a devastating environmental impact.
In contrast, solar power is a clean, renewable energy source that does not release any harmful gases into the atmosphere.
The less energy you use from the grid, and the more renewable energy you produce yourself, the lower your carbon footprint. Solar panels can be a major step towards living a more eco-friendly lifestyle.
Electricity prices are on the rise and it seems that both gas & electricity bills will continue to increase, and there's very little we can do about it. Fossil fuels are a finite resource after all, so in the long term they will only get more expensive.
As energy prices go up, so does your power bill. Many families cringe whenever they hear of the latest electricity price rises which continue to squeeze household budgets.
But if you have solar panels, you're protected against all that. Once your solar system is installed, your electricity is free, and any energy price increase only means you're saving even more.
The price of solar panels has gone down dramatically in recent years, so it's no longer expensive to install solar on your home.
In fact, many homeowners report that they have seen a significant increase in the value of their property once they've installed solar panels and can now advertise to buyers that their home is already "energy independent".
The solar energy benefits we've already discussed will be as attractive to a buyer as they are to you, and most good realtors would agree that a solar installation will add substantial value to any home.
A typical solar panel warranty period is 25 years and some manufacturers offer a 30 year warranty (but only for the first owner).
Solar panels aren't entirely maintenance free, but they require very little upkeep. They run very efficiently with minimal maintenance, and there are very few moving parts that need to be replaced.
After installing your solar panels, you simply need to clean them regularly to maintain optimum performance.
Grid-linked solar systems can power your home, but they can also make you some extra income on the side.
If your solar panels generate more electricity than you use, then depending on what state you live in, you can sell it back to the grid (known in the US as Net Metering). There are similar schemes available in Canada, the UK and other countries around the world.
If you don't have the facility to store your excess electricity then this is a great way to make sure it doesn't go to waste and also to further reduce your bills.
The Solar Investment Tax Credit is a US government subsidy that is one of the main reasons for the recent rise in the solar industry.
The ITC currently stands as a 26% credit on domestic solar power installations (until 2022) but is due to be phased out by 2024. So if you want to take advantage of this, you need to act soon.
Depending on where you live, you might also find further incentives available at a state or local level which can drive down the cost of your home solar system even further.
We've spoken about the benefits, however there are also some potential disadvantages of solar energy that you need to consider.
When you install solar panels, there is a large initial cost involved. Although he cost of installation is much cheaper than it used to be, and the government incentives and tax breaks help, the cost may still be beyond some people.
You should look at solar energy as a long term investment. Although costs and electric bills vary, typically it takes around 8 years for your home solar power system to pay for itself. After that, you can enjoy free electricity for the remainder of the life of your system.
Home solar systems take up a lot of roof space, so they won't be suitable for everyone. If you live in a condo or another shared building for example, you may not have access to the roof, unless you can persuade the management company and other residents to install communal solar panels.
Even if you have a single family dwelling, you will find that certain types of roofing material, such as slate, can make it difficult to install solar cells.
However, your roof is not the only way to access solar energy at home. There are other solar technology alternatives you can look at, such as ground solar cells in your garden.
Once your home solar system is installed, it generally stays where it is. Solar systems are extremely difficult to move, so if you are planning to move house in the near future, you probably won't be able to take it with you.
You'll probably recoup most of the cost through the increased value of your property when you sell it, but you would need to install solar power again at your new home if it doesn't already have its own solar system in place.
It may seem obvious, but many people overlook the simple fact that solar panels only produce electricity when there is sunlight, so they don't work at night.
If you remain connected to the grid, that's not a problem. You can simply use the grid's power at night, and generate electricity from your own solar panels during the day (selling back any excess to keep your electric bill low or zero).
However, if you intend to go off grid, you need a way of storing it so you don't lose power at night.
If you want to go off grid entirely, you need to invest in solar batteries to store your excess solar energy so that you still have power when your solar panels aren't generating electricity.
A solar battery such as the Tesla Powerwall can cost up to $7,000 and you may need more than one depending on how much solar energy you produce and how much power your home consumes.
The cost of storage is currently one of the main disadvantages of solar energy.
However, solar technology is improving all the time and prices will reduce over time. In the meantime, you can always opt for a net metering solution and still benefit from all the advantages of solar energy.
Although it is possible to install a solar panel system yourself, it is a job that's probably beyond the scope of most DIYers. Therefore, most of us will need to find a competent local tradesman to do our solar panel installation.
Be sure to do your research and don't be swayed by pushy salesmen. Contact more than one solar company in your area and compare prices and reviews before deciding which one to buy from.
There are pros and cons of solar energy, and it might not be right for everybody. A home solar system is a source of renewable energy that can save you a lot of money on your electricity bills, while reducing carbon emissions.
However, despite being a good long term investment, the upfront costs and other cons of solar energy does mean it's not suitable for everybody.
I personally have solar panels on my home, and I don't regret that decision for one second. But you need to examine the facts as I've explained them above and decide whether it's the right move for you.
Yes you can, depending on where you live. If your solar panels produce more energy than you use, then you have the option of selling the excess energy back to the grid.
You can store solar energy using technology that is currently available, and many families have chosen to do this and go "off grid."
However, storage is expensive and might not be within everyone's price range at the moment.
Yes, it's highly likely. As with any evolving technology, we would expect the cost of a home solar system and solar batteries to reduce over time.
However, government tax incentives will start to wind down soon. Also if you decide to wait for prices to reduce, you'll still be paying full price, be vulnerable to increasing electricity costs AND contributing to ongoing pollution from fossil fuels.
So waiting for solar panel costs to come down may not actually be a financially or environmentally sound decision.
NASA scientists say that the sun will continue to shine for about another 5 billion years, making it the most reliable renewable energy source at our disposal.
Your home solar systems won't last as long as that, but they are guaranteed for at least 25-30 years and could conceivably last a lot longer than that before they need to be replaced or upgraded.
Adding solar panels to your home is the perfect way to cut your electric bill, and reduce dependency on fossil fuels that harm the environment.
A home solar system can generate power from the sun's energy for many years to come. It pays for itself after around 8 years, giving you free power for the remainder of its lifespan.
We've examined all the solar energy pros and cons, and yes there are a few potential drawbacks that mean solar energy isn't for everyone right now. But if you do have a suitable home and the money to invest, solar systems are a fantastic way to reduce both your environmental impact and your electric bill.
