Choosing solar panels isn’t easy. There’s deciding on a location, the type of solar panel material, and what company to hire.
One of the most important steps when setting your home up with solar power is determining how many solar panels you want. More solar panels will generate more power, but they’ll cost more upfront. Your home solar panels may also be limited by how much space they’ll require.
Here’s how to best decide how many solar panels you should invest in.
Choosing Solar Panels
How many solar panels you purchase will partly depend on the type of solar panel. There are three main types available: monocrystalline, polycrystalline, and thin-film.
Monocrystalline panels have higher efficiency and performance but cost more than the other three. This type appears black with a smooth appearance.
Polycrystalline panels are the most affordable option but are less efficient than monocrystalline. They come in a blue color.
Thin-film panels are unique in their portability and flexibility. They offer the lowest efficiency and performance but they’re thin and discreet.
While thin-film panels are discreet, you may require more of them than monocrystalline panels for the same energy production.

How Many Solar Panels Is Enough?
The easiest way to determine how many solar panels you’ll need is to use a solar calculator available online. Put in your address and monthly power bill to figure out the right number of panels.
For a 1500 square foot home and an electric bill of $100 a month, you may need around 15 solar panels. You could also install more panels than is recommended if you plan on earning credits from your electric company.
You’ll still need to have a solar provider inspect your area before installation. There may be too much shade on your home or not enough space for the number of panels you want. You could also meet your power requirements with fewer panels of one type than another.
Benefits of Solar Energy
One of the most well-known benefits of solar energy is that it’s good for the environment since it’s a renewable resource. However, it’s also efficient.
Once an expensive option, the costs of solar PV panels have dropped by nearly 70 percent. Some electric companies offer credits per kWh of electricity your solar panels produce. Whatever you don’t use goes back into the grid and can lower your energy bill.
Your property also gets a boost in value with solar power.
Buying Solar Panels
So, how many solar panels will your home need? If you own a large home with a sizable energy bill, you may need a more extensive setup than other houses. Or you might settle for a discreet option that helps you save money.
Either way, there’s never a bad choice when it comes to decreasing your carbon footprint.
