How Many Solar Panels Will I Need?

The square footage of your home depends on how many panels you'll need. Let's say you own a 2,000 square foot home. You'd need at least 4,000 watts to power your home.

That said, you'll need roughly around 12 to 18 panels. It may seem like a lot but it's what'll keep your electric bill nice and low.

How Long Do They Last?

Since the panels sit out in the sun all day long, you'd think they wouldn't last long. On the contrary, they can last anywhere from 25 years onward.

Do They Need to Be Cleaned?

Solar panels are technically self-cleaning but it's good to give it a once-over every now and then. Bird droppings can accumulate, which will affect the efficiency of the panels.

For those who live in dusty areas like the desert, make sure it doesn't become stuck on. Dirty solar panels mean they won't be as efficient.

Do I Need a Permit?

To put it simply, yes you will need a permit. There's a lot of factors that go into installing solar panels.

You'll need to comply with regulations and safety rules from the state, local boards, and federal building laws.

How Much Do They Cost?

Solar panels don't come cheap. For most companies, you pay by the watt. It varies between $7 to $9 but could be more.

You can pay upwards of $25,000. It really depends on the company you work with and the kind of panels you purchase.

How Many Types of Panels Are There?

Since solar panels came on the scene, there's different technology associated with each type of panel. The most common types are monocrystalline and polycrystalline.

However, there are several different types. If you're really committed to purchasing solar panels, be sure to do your research to decide which type is right for you and the type of building/house you own.

What Are Some Disadvantages?

While you hear so many great things about solar panels, you wonder if they are any downsides. As with anything, there always are some cons.

For solar panels, one is cost. They are relatively expensive to install.

Another is that they're weather dependent. Let's say you live in Oceanside, CA. There's plenty of days where it's an overcast.

However, a few clouds don't always affect the efficiency of the panels.
