How Does a Solar Energy System Work?
As you explore the different options for embracing solar power, it may be helpful to have a baseline understanding of how solar energy systems actually function.
Generally speaking, solar energy systems involve solar panels installed on your roof. These panels absorb the sun's energy, storing it in what are known as photovoltaic cells. These cells convert sunlight into direct current (DC) energy, which an inverter changes into alternate current (AC) electricity. AC electricity is what you need to power your home.
It's important to note that, before you purchase solar panels, it's worthwhile to meet with a solar energy consultant who can tell you more about how many panels your home will require and how those panels should be ideally positioned on your roof.
One more note: If you're concerned about the affordability of solar power, it's important to remember that most top solar companies provide a host of options, including flexible financing and programs to lease a system rather than purchase it outright. As you talk with different solar panel companies, don't hesitate to inquire about pricing.
Benefits of Solar Energy
Installing solar panels on your home can yield a number of benefits. Here are just a few examples:
One of the main reasons why homeowners choose to install solar cells is that it allows them to truly embrace clean energy sources. Rather than depend on fossil fuels, you can power your home with renewable energy that comes straight from the sun. This can be a highly effective way to minimize your environmental footprint.
Solar Tax Credits and Rebates
There are a number of ways in which choosing renewable energy can save you money, starting with the fact that there are so many rebates and tax credits available. Both federal and state governments have adopted a list of financial incentives to make solar power more attractive and accessible to homeowners.
Lower Electricity Bills
Finally, embracing solar power will help you save money by slashing your electricity bills. Most top solar energy companies offer online calculators that allow you to see for yourself how much money you'll save over time simply by changing to a renewable energy source. There is also an option called a power purchase agreement (PPA) that can allow you to host a solar or renewable energy system from a utility provider in exchange for lowered energy rates. If your solar panel system generates excess energy, the utility will then purchase that energy from you in the form of a net metering credit on your bill.
Narrowing Down the Top Solar Companies for Your Home
While there are many perks to choosing solar energy for your home, installing panels can be a rather daunting endeavor. However, working with one of the top solar companies in your area can greatly simplify the process.
When seeking the best solar energy company for your home, remember to look for an installer that's well-regarded within the industry, get a consultation before you buy and always be sure to ask some direct questions about the financing options that are available to you.
