How Much Solar Do I Need?

How many solar company manchester nh do I need? How many solar panels will I need? These are all common questions that anyone who wants to install solar energy in Florida will have. Your current energy consumption is the key to finding out the answer. So, dig out your recent energy bills. Here’s how you can calculate how much solar you need:

Use Our Solar System Sizer Tool

is a handy tool to calculate how much solar power you will need. Here’s how it works.


  • Reduce your energy costs.
  • Keep track of the highest, lowest and middle daily kWh usage. If you have 12 months’ worth of bills, you can view the highest, middle, and lowest monthly bills and then use them. If you don’t have the information, your energy company should be able to give it to you.


  • Our calculator will calculate your monthly average kWh consumption or cost.


  • To see how much solar you will need, check out our solar calculator chart.

Example Calculation: How Much Could I Save?

Here’s an example of how much money you could save. Our system size calculator has been used:

  • The highest daily kWh consumption: 53 kWh
  • 42 kWh is the middle daily kWh consumption
  • 28 kWh is the lowest kWh consumption
  • Annual Kilowatt Use Calculated: 14,965

This calculation shows that our recommended solar system size is an 11.59 kW system, which would be Florida Power Company’s top-selling system. Here are the savings that we could make with an estimated production of 17,458 and 1,455 kWh each month. $2254 yr/ $187.83 per month.

What Types Of Solar Panels Do You Need?

We’ll calculate how many solar panels are needed based on how your roof is set up, your location, and your kWh requirements.

Why Install Solar Panels?

You’re now able to calculate how much solar energy is needed. What now? Now it’s time for you to install your solar system. Here’s why:

Solar PV Reduces Electric Bills

You can save a lot by reducing your energy bills, as you can see from our calculations. Our example shows that you could save more than $45,000 over 20 years. No matter how big or small your solar system is, you will save money. This is a fact.

It is a proven and tested method. You can convert the sun’s rays to electricity at your home. Your solar panels can power your lights, appliances, and computers.

Net Metering

You can even get your money back with Net Metering. You can use excess solar power to feedback into the grid through net metering. Your energy company will reward you for doing so. You can save even more!

Solar PV Is Much Better Than Hybrid Heaters

The cost of solar panels in Florida is dropping in recent years. This has led to increased benefits for heating water with solar electricity. Water heaters are known for being energy-hungry and can lead to high electricity bills.

Solar panels will power your water heater with constant free energy. No need to worry about long showers. You don’t have to pay bills if you produce enough electricity.

Florida Sunlight Hours For Your Location:

Are you worried about getting enough sunlight to your Florida solar panels? It’s known as the “Sunshine State” for a reason.

  • January 6.9 hours
  • February 8.2 hours
  • March: 8.4 Hours
  • April: 9.3 hours
  • May: 10.9 Hours
  • June 10.7 hours
  • July 10.8 hours
  • August: 9.5 Hours
  • September: 8.9 hours
  • October: 7.6 Hours
  • November: 6.5 Hours
  • December: 6.3 hours


Average KWH Consumption For Applience

You can analyze your appliances to find out how much solar energy you require. This is an average appliance energy consumption.

  • Refrigerator: 600 kWh
  • Air Conditioning Unit: 215 Kilowatts
  • Central Air Conditioning:1,000 kWh
  • Electric Vehicle: 3,000 kWh
  • Heated Swimming Pool: 2,560 kWh
  • Hot Tub (outdoor),: 3,300 kWh
  • LED TV: 432 Kilowatts
  • Desktop computer: 194 Wh
  • Laptop: 150 kWh

What Impacts Solar Panel Efficiency

There are many factors that can influence this. For example, the angle of your roof and shade from nearby trees. Florida Power Services designs solar systems that provide year-round energy production.

It is also important to consider the quality of the panels. Companies may use lower-quality materials than us, which can lead to poor sun ray absorption. You should be wary of whole solar roofs made from solar tiles. They are less efficient than regular solar panels and have a more attractive appearance.

How Large Is Your Battery Size

Solar batteries store the excess solar energy generated during the day and save it for nighttime or low-sunlight days. We consider the following factors when planning a battery installation:

  • Your average kWh demands.
  • What time you’ll be without power during the night and on cloudy days.
  • You can make a profit immediately to get the best return on your investment.

Grid or Off-Grid

The most important factor in deciding the size and layout of your solar power system is whether or not you wish to connect to the electricity grid. You can rely on the grid’s electricity at any time, even during the night, if you are grid-tied.

However, if you decide to go off-grid you will need to ensure you have enough energy for the day. Usually, there is more space available to meet your kWh needs.

The off-grid solar system is completely disconnected from the main grid. These systems are often used by those who want to live in rural areas and have a 360-degree green vision. Off-grid solar systems require solar batteries, which are more efficient than grid-tied systems.

Save Thousand Of Dollars In 2022 By Acting NOW!

If you wait, your solar panel installation in Florida could cost thousands of dollars.

Florida’s solar tax incentives are responsible for this. You can save 26% on your installation costs for solar power in 2021. That’s $7,800 for a $30,000 solar installation!

The federal solar tax credits for 2024 will be 0%. In the past, we have seen customers regretting delaying their installation as they missed out on higher tax credit savings. Don’t wait!
