Thinking about starting a new solar panel installation in Oahu? It can be very exciting to start a new venture into solar energy. However, most people don’t know where to start. Finding sunshine in Hawaii is not the problem, but figuring out the best way to harvest it can be a bit challenging. That is one reason why you should consult with a professional company that has experience with solar panel installation. A professional solar company can help simplify the process so that converting to solar energy is a simple process.

Still, before you get to that point you are probably wondering about some of the basics. Almost everyone questions how many panels they need first off. After all, the overall price of your installation will be heavily dependent on how many panels you need to be installed. Several factors determine the proper size of a home solar system. Here are just a few things you may want to consider before calling a solar panel installation company. If you aren’t sure how to interpret these facts, there is no reason to worry. Give a company a call and they should happily be able to help you figure out the answer as well.

Personal Energy Usage

The most reliable way to determine how many solar panels should be in your home is by analyzing your actual personal energy usage. However, it can be hard to come up with that exact number if you are not used to tracking your energy usage or are not able to read a detailed energy statement. If you are just starting to consider solar panel installation, you probably just want more of a ballpark than an exact answer. With this in mind, you can use a few benchmarks to give you a rough idea of how large your solar system needs to be.

Keep in mind that the following estimates are based on what the average use of energy is in a home. Everyone has different levels of energy use, but these averages can help give you a rough idea. They also help address certain issues such as whether you can afford a solar panel installation or if your roof is large enough to handle the appropriate amount of solar panels. If you decide to go forth with a solar panel installation, a professional company can give you a much better, and highly accurate estimate of the full costs.

Square Footage of Your Home

One of the most basic ways to figure out how many solar panels you will need is to compare the typical system size against the square footage of your home. This estimate essentially estimates how much energy is consumed based on the overall room inside your home. A larger home would, therefore, require more energy to heat and light than a smaller home. A small home with only 1,000 square feet would only require about 8-9 panels depending on their wattage, whereas a home that spans 2,000 square feet would require about 15-17 watts.

Number of Bedrooms in Your Home

Not everyone knows how many square feet their home is off the top of their head, so it may be easier to look at the number of bedrooms in your home. Once again, the figures are based on the idea that more homes will consume more energy. If you have a three-bedroom home you should plan on about 16-19 panels whereas homes with five bedrooms may require closer to 26-31 panels. The number will continue to rise dependent on the number of bedrooms you have. Homes with a small number of bedrooms, but larger than normal shared spaces should consider adding an extra bedroom in to get a realistic idea of what they need.

How Many Solar Panels Do I Need to Cut My Electric Bill?

This question is a bit harder to answer because there are several factors involved in the answer. First of all, you need to know how much you pay regularly which can vary widely. Homes that consume less electricity will require fewer solar panels. The wattage of your solar panels will also impact how many you need. 375W panels may cost a little bit more, but since they can harvest more energy you won’t need to install as many. Finally, the actual rate you pay for electricity in Oahu plays a large role in determining your energy usage based on this metric. That said, the average US electricity rate is 13.3 cents, so based on this metric, if you pay $60 a month then you will need 9-11 solar panels whereas a home that spends about $80 on electricity will require about 12-14 solar panels. A home that consumes a small amount of electricity with an average bill of $40 will only need about 6-7 panels.

Do You Know Your Exact kWh Usage?

All of the estimates offered above are designed to give you a ballpark idea of how many solar panels you will need for your solar panel installation. If you know your monthly kWh usage then you can accurately figure out how many solar panels you need in your home. Pull out your monthly electric bill and look for your energy usage. Energy is measured in kWh. For an accurate result, look at your usage over the past year so you can account for ups and downs in usage based on seasonal changes.

You can figure out how many panels you need on your own using the above metrics, but if you are serious about solar panel installation then it is a good idea to contact a company to find out what you really need.
