They continued: “Angelo told me that acquiring the permit would take until December or maybe even January, but they came out a couple of weeks ago and it's already up and done.

Should I go solar?
Going solar isn’t for everyone, but it can benefit large portions of the population. When you’re purchasing a solar energy system, the most important qualifying factor is homeownership. If you’re a homeowner, you can evaluate your candidacy by talking directly with solar panel installation companies and doing some basic research on your property and your state’s laws, limitations and incentives.

Is my house a good candidate for solar?
If you’re trying to determine whether your house is a good candidate for solar, you can look into these three components on your own before contacting a solar company:
- Your electricity usage
- Your home's sun exposure
- Your roof's size, orientation and condition
How much electricity you use is a huge factor in going solar. If your home is already energy efficient, a solar energy system may not make sense over the long term. Your property also needs to get enough sun, and you need enough roof space for the panels to be installed effectively.
The condition of your roof also matters; solar panels can last for 25 years or more, so they’re best on a roof that won’t need replacing midway through the energy system’s life.

Pros and cons of going solar
With several individual factors at play, the benefits of going solar vary on a case-by-case basis. In general, however, the pros and cons remain true for most installations
Pros
- Reduced electricity bills
- Increased property value
- Lower carbon footprint
- Possibility of operating off-grid
- Long product life and warranty periods
Cons
- Large investment costs
- Not a one-size-fits-all solution
- Some aesthetic concerns
- Possibility of bad contract or installation
The primary benefit of going solar is the reduced cost of electricity. Most homeowners see significant financial benefits when they switch from utility-powered electricity to solar energy. Homes with solar also attract both environmentally and financially conscious buyers, so they tend to sell faster and for more money than others.
In terms of solar energy disadvantages, most can be avoided by working with a reputable company. While shoddy installations and bad financing rates can cause a drop in solar panel value, most professionally installed systems experience few issues and pay for themselves before long.

FAQ
How does solar energy work?
In simple terms, modern solar energy systems work by harnessing the power of the sun and converting it into usable electricity. With solar panels interconnected to the utility grid, homeowners in areas with net metering programs can get credit for excess electricity production on monthly bills.
How much does a solar installation cost?
The total price of a solar system can vary quite a bit based on system size and local availability, but most homeowners in the U.S. can expect to pay between $14,000 and $18,000 for an average 6-kW system. While this may seem like a lot of money, you have to consider the price of solar versus the cost of utility electricity. In most cases, the cost of solar panels will be lower than that of utility energy over an extended period of time.
How does the federal solar tax credit work?
The federal solar investment tax credit (ITC) can reduce your total solar installation costs by up to 30%. Applied against your federal income tax liability, the solar ITC represents a dollar-for-dollar reduction in avoided tax payments. For example, if your solar energy system costs $18,000, you may be eligible for a federal income tax credit of up to $5,400.
How many solar panels do I need?
The number of solar panels you need for your installation depends on the amount of electricity you’re hoping to produce and the type of panels you use. A typical American home requires about 19 solar panels to match its energy consumption, but many homeowners choose to size up their systems for protection against increased electricity use on the property.
