What are 5 key pros and cons of solar energy?

The 5 key advantages of solar energy:

1. Reduced Electricity Bills: Solar panels can significantly cut down or even eliminate your monthly electric bills. When you install a solar power system in your home, you generate your own electricity and become less dependent on the utility company. This will result in a reduction in your electricity bill. A typical solar panel system has a lifespan of 25 to 35 years, which means you can save on electricity costs for many years. In the past decade, the cost of solar has declined by over 70 percent, while the cost of electricity has increased by around five percent. By going solar, you can take control of these rising costs.

2. Increased Home Value: Many homeowners are interested in installing solar panels but are unsure about its impact on their homes. Studies have shown that installing a solar system can increase your home’s value by approximately four percent. Even if you are planning to move in the near future, installing solar panels can provide a return on investment when you sell your home. It is a good investment for most homeowners, regardless of how long they have lived in their homes.

3. Decreased Carbon Emissions: Solar energy is a clean, renewable source of energy that reduces carbon dioxide and other greenhouse gas emissions, minimizing your environmental impact. Unlike traditional fossil fuels like coal, oil, and natural gas, solar energy does not directly release pollutants like carbon dioxide into the atmosphere and water supply. Solar has a lower environmental impact compared to even nuclear energy.

4. Protection against Rising Energy Costs: When you install solar panels on your home, you lock in energy costs for the next 25+ years, provided you own the system. After you have paid off the initial cost of the panels, you will generate your own electricity for free. The federal solar tax credit also offers a 30 percent tax credit for newly installed solar systems, reducing up-front costs.

5. Potential for Profits: In some states, solar incentives can result in profit in addition to bill savings that pay off the cost of the system. Solar Renewable Energy Credits (SRECs) reward you for the electricity generated by your solar panel system. If you live in a state that offers this incentive, you can expect immediate and long-term returns from your solar investment.

The 5 key disadvantages of solar energy

1. Not all roofs are suitable for solar panels: The installation of rooftop solar panels involves attaching a mounting system to the roof. Roofing materials like slate or cedar tiles used in older or historic homes can pose challenges for solar installers. Moreover, rooftop additions like skylights or roof decks in homes or apartment buildings can make solar installation difficult or expensive. Despite these challenges, the widespread adoption of solar power in the US should not be hindered in the long run. If your roof is not suitable, you can still go solar by installing ground-mounted panels or participating in a local community solar farm.

2. Solar may not be the best option if you plan to move soon: Although solar is a smart financial investment, it can take several years to break even – the average payback period in the US is 8 to 9 years. For a young homeowner who may be moving soon, installing solar panels may seem like an unwise investment. Nevertheless, as discussed earlier, solar can enhance property value and increase returns when selling the home. Most solar panel system warranties are transferable, allowing the new owners to take advantage of the warranty that came with the panels you installed. Hence, this drawback of solar energy can be overcome if you plan to buy the system through a cash purchase or loan.

3. Low electricity costs limit solar savings: The primary advantage of solar energy is reduced consumption of electricity from utilities, leading to monthly savings. However, this only applies if the homeowner has high electricity bills. For example, in a state like Louisiana where electricity is often 25% cheaper than the national average, solar panels may not be as appealing as in Hawaii where electricity costs are more than double the average rate.

4. Up-front costs of solar can be overwhelming without financing: The cost of a solar panel system depends on various factors like tax credits, rebates, and financing options. While you can obtain an average cost of solar for your state or a personalized estimate for your home, the up-front cost of solar can be significant if you do not qualify for a zero-down solar loan. This drawback of solar energy is clear: not everyone has the funds to make such a large investment with an upfront payment. However, there are various solar financing options available, including state-backed loan programs, leases, and power purchase agreements, to help overcome this obstacle.

5. Solar panels don’t work without sunlight: Solar panels need light from the sun to absorb energy and therefore don’t work at night. To overcome this, you can pair your solar energy system with energy storage, enabling you to use excess energy generated and stored in solar batteries even during the night. If you live in a state with net metering, the excess energy can be sold back to the grid for credits on your electric bill.
