The Cost and Benefits of Solar in Johnston
Even though solar panels can save you money on energy over time, it's necessary to take into consideration the upfront costs. Some important things that affect the cost and possible savings include:
- The amount of sunlight your city gets: Because of Johnston's high amount of average daily sunlight, you should be able to save a decent amount on your electricity bills.
- How much you spend on energy: If your local electricity rates are high, there's a good chance you'll have a higher return on your investment in a solar system. In Johnston, you can save an average of $73 a month on your electricity bills.
- Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $20,000 over 20 years on your energy bills.
- Choice of solar panels: The type of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
Solar is a fruitful investment for most homeowners. You can generate your own electricity instead of paying for it from a utility company and take advantage of solar incentives, all while helping protect the planet.

Environmental Impact of Switching to Solar in Johnston
One of the most compelling reasons to adopt solar power is to minimize your dependence on traditional energy sources like burning fossil fuels, which are destructive for the environment. But you may be curious — how much exactly can you help the environment by making the switch to solar? No matter where you are, you can help save the planet by switching to solar energy, but homes that use lots of energy will have an even bigger impact. Since solar panels don't release CO2 emissions into the atmosphere when producing electricity, they're a good trade for traditional energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. The good things about solar power are abundant — just like solar power is! That's why so many Johnston residents have been happy with committing to solar.
