The Cost and Benefits of Solar in Islip
We get that for most homeowners, the choice to invest in solar rests on installation costs. Some significant things that impact the cost and possible savings include:
- System size and type: Some models are more costly than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
- Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $22,000 over the first 20 years with your solar system, too.

On top of the federal solar investment tax credit, there are also some local incentives, which in the majority of cases, can be claimed in addition to the federal incentive, so you get to save even more. Our article on solar incentives goes over more in-depth information on the incentives you can benefit from in Islip.
Environmental Impact of Switching to Solar in Islip
There are a few big reasons why homeowners are interested in solar energy: for the financial and environmental benefits. But you may be wondering — how much exactly can you help by making the switch to solar? One thing to consider is your overall carbon footprint. For example, if you have a long commute time and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. In fact, if you install solar panels, you could lower your carbon dioxide emissions by about 100 pounds each year. Since energy from the sun is renewable and makes electricity without a carbon footprint, adding solar panels to your home is one easy step you can take to help protect the environment.
