How Much Energy Do Solar Panels Produce

The Climate You Live In

Solar Basics Pt 2: How Much Energy Does One Solar Panel Produce?

Climate will undoubtedly affect your solar power production. The more days of sunshine your area has per year, the more solar energy youre going to produce.

However, even if you live in a harsh winter climate, you can still generate a fair amount of solar energy.

For example, homeowners in Californias Central Coast and parts of Colorado experience an average of 300+ days of sunshine per year. In comparison, a homeowner in Maine or New Hampshire will probably only get about 200. While thats 100 fewer days of sunshine, a Northeast homeowner will still have the potential to produce 50-60% of their annual power supply through solar energy.

At the start, it may not seem like much. But over 30 years, the energy savings will add up fast. All the more so when you factor in net-metering programs, federal tax credits, and local and state solar rebates.

If youre still on the fence about whether solar panels can produce enough energy for your needs and budget, contact a professional solar installer who will walk you through the entire process. At Photon Brothers, we offer free, no-obligation virtual or in-home solar estimates!

Local And Federal Tax Incentives

Solar tax incentives and rebates are offered on the federal and state levels. For example, the federal tax credit offers a 26% credit on installing residential solar systems through the solar investment tax credit .

Other solar incentives vary from state to state. For example, Florida offers homeowners the Property Tax Abatement for Renewable Energy Property. This incentive adds more value to your solar installation through a 100% property tax exemption for residential renewable energy property, as well as an 80% property tax abatement for nonresidential renewable energy property.

We encourage you to use the Database of State Incentives for Renewables & Efficiency to learn what other rebates and solar tax credits are available in your state.

How Much Solar Power Will You Need

To determine your homes average energy requirements, look at past utility bills. You can calculate how many solar panels you need by multiplying your households hourly energy requirement by the peak sunlight hours for your area and dividing that by a panels wattage. Use a low-wattage and high-wattage example to establish a range . Note that the size of your roof and how much sunlight your roof gets are factors as well.

If you work with an experienced solar installer, they will handle all these calculations for you. If youre searching for a calculator to figure out how many solar panels do I need?, look no further. You can use SunPower Design Studio to estimate your own system size, monthly savings, and the actual appearance of a solar array on your own roof.

How Many Solar Panels Do I Need For My Business

How Much Energy Do Solar Panels Produce?

The number of solar panels that you require to fit the power needs of your business will be dependent on varying factors.

First, you will need to know how much power you use per day or month. That is based on the equipment and appliances you have in your business.

Each device requires different amounts of hours. Therefore, you have to add the power needs of all of them to determine how much power you need.

For example, if your business uses an average of 25,000 kWh of electricity per year, it is logical to say that you need around 70 kWh per day . The next step is to know how much electricity an average solar panel produces.

For example, the standard panels produce an average of 1- 1.5 kWh per day. If you take 1.5kWh as the average, then you will require at least 47 panels.

The calculations would be like this / 1.5kWh per day = 47 panels.

Therefore, the larger the business, the more the power needed and hence, more solar panels to cover the electricity needs.

Also, due to varying factors like sunlight and the efficiency of the solar panels, businesses in some areas may require more solar panels than others.

The difference can occur even though both companies need the same amount of power.

Price Comparison Between Solar Panels And Solar Shingles Or Solar Roofs

Trying to compare the prices of rooftop solar panels to BIPV solar roofs is a bit of an exercise in futility due to a significant number of variables that would need to be considered. The biggest one being, that to mount standard solar panels on a roof, you need to cover that roof in the first place. Solar shingles are in themselves a weather protective solar roof cover AND a power-generating solar panel.

The average per-watt price for an old-school rooftop solar installation currently ranges between $2.57 and $3.35 USD, and the average total price for a full solar panel setup in the US averages between $11,411 and $14,874 after any regional solar-tax credits are applied. Again, thats an average incentives vary, and not all states will have tax incentives and rebate programs.

The above may seem a lower price than a full solar roof installation, until of course you add the cost of a roof covering, and possibly having to remove panels in fine working order simply to replace defective shingles beneath them. And, to add additional types of apples to compare with these oranges you also have aesthetics, durability and home resale value to consider.

Where BIPV solar roofs really pull away from solar panels is the lack of hassle with roof coverings, and the cool factor. They just look cooler, full stop. And we are probably all attracted to shiny things a bit more than we may like to think. : )

How Big Are Solar Farms

A typical solar farm is usually several hundred acres.

But, they can be as big as thousands of acres or even bigger in some cases.

It all depends on how much power you want to produce and the efficiency of your solar panels.

As the higher the solar panel efficiency, the more energy your produce per square foot. Thus, the less land you need.

Powering Your Home With Solar Energy

Now you better understand how much solar electricity you can expect from a single solar panel and an entire solar panel system. However, installing a solar system does more than just help the environment by using renewable energy it saves you money.

When you use electricity produced by rooftop solar panels, you aren’t using the services of a utility company. This means they do not have to charge you. If you can install enough solar panels to cover all of your electricity needs, you can save between $90 and $100 every month.

Of course, this is only an estimate. As you now know, several factors contribute to how much electricity your solar panel system produces.

How Many Solar Panels Are Needed To Power An Average House

How Much Power Does A 5kW Solar System Produce?

This is a seemingly simple question, but it is not. Since your locations can heavily influence the solar output, you need to take the weather conditions, direct sun hours, and something else into consideration when thinking of this question.

Also, different houses have unique solar panel systems for distinctive purposes. So you may need different numbers of solar panels. But to figure out the typical panel numbers, you can check out in an article the average number of solar panels required to power the average home in each state.

    A kilowatt-hour is a basic unit of energy, which is equal to power times time . Your electric bills show how the average number of kWh you use per month.

    For example, a 50 Watt light bulb left on for one hour would be 50 Watt hours, and 20 50 watt light bulbs running for one hour would be 1 kilowatt-hour . According to the U.S. Energy Information Administration, the average monthly electricity consumption for a residential utility customer is about 903 kWh per month.

    Divide your average monthly usage by 30 days in a month to get your daily usage. If youre going by the national average, then you should be using about 30 kWh per day. Next, figure out the average amount of sunlight you get per day. The US ranges from about 4 hours 6 hours of sunlight per day, on average, see the below map. Lets estimate you get about five hours per day to generate that 30 kWh you use. So the kWh divided by the hours of sun equals the kW needed. Or, 30 kWh / 5 hours of sun = 6 kW of AC output needed to cover 100% of your energy usage.

    Should You Install High

    If youve ever looked up How much energy can a solar panel produce youve probably come across solar panel efficiency somewhere. Heres the deal – its way more important to look at a panels wattage than it is to look at its efficiency rating.

    Why? Because the panels efficiency is taken into account when the power rating is calculated. You see, the power rating of the panel serves as the cap of how much electricity the panel can produce .

    So, if Panel A is 370 watts with a 19% efficiency rating, and Panel B is 360 watts with a 21% efficiency rating, it doesn’t matter that Panel B has a higher efficiency rating – it will only produce 360 watts. Panel A, despite having a lower efficiency, will be able to produce more.

    Types Of Solar Farms: Utility

    How Much Power Does a Solar Panel Produce? · HahaSmart

    There are two main types of solar farms around the country: utility-scale solar farms and community solar farms. The main difference between the two is their customers, as utility-scale solar farms sell directly to utilities, while community solar farms sell directly to end-consumers of electricity, such as homeowners and renters.

    What Factors Affect Solar Gain Or The Amount Of Sunlight That Hits The Panel

    Your geographic location, specifically latitude and longitude, is very important. But even if youre in a prime solar area a few things affect the amount of sunlight on the panels themselves:

    • shading
    • roof tilt
    • roof direction

    Most solar arrays are installed on your roof, which is essentially unused space. Occasionally ground mounts are used if the roof conditions are not ideal for putting up panels.

    Roof direction and tilt are extremely important for total solar output. In the northern hemisphere South facing roofs will get much more sunlight than those facing the North. The angle of the roof also plays into the total amount of sunlight that hits the panels.

    Shading is probably the biggest enemy of solar: if trees around your house block sunlight from the roof for large portions of the day its likely to take a major chunk out of solar output. Debris from vegetation and other things like snowfall or dust can also obscure the panels and prevent sunlight from entering them.

    Is A 100w Panel Big Is It Expensive

    100W panels come in different sizes as this largely depends on their design and efficiencies however, their measurement is approximately 47 x 21.3 x 1.4 inches.

    For starters, there are two options for you: purchase a 100W solar panel kit or get the 100W solar module. The kit already contains the charge regulator, solar module, brackets, and cables needed for installation.

    The price of solar panels largely depends on their efficiency, the brand you choose, and the equipment contained in the package upon purchase. 100-watt starter kits that cost roughly $300 or above are available in the market, or you may also consider a standalone 100W panel that costs $100 more or less.

    Lastly, the solar panels efficiency may depend on several elements such as the materials, solar manufacturer, and quality of the unit.

    How Efficient Are Solar Panels

    Calculating the KWH Your Solar Panels Produce

    The efficiency of a solar panel refers to its ability to convert sunlight into electricity, the more efficient the panel, the more electricity it creates. In the 1950s, the average solar panel array was only capable of converting 6% of sunlight energy into electricity. These days, the average home solar panel array can convert 15% of the suns energy into electricity, with the most efficient models being up to 22.5% efficient.

    However, there are loss factors that can result in a slightly lower energy output than what is on the label. These include:

    • Shading shadows can prevent the panel from receiving the maximum amount of sunlight.
    • Temperature ironically, solar panels perform better at lower temperatures so higher temperatures mean lower efficiency
    • Reflectivity the solar panel will be more efficient if less light is reflected from it, highly efficient panels appear blue or blue-black

    What Determines The Amount Of Electricity Produced

    There are actually four main factors that will determine how much electricity your solar panels will be able to produce for your home. These are as follows:

    The size. This is the most important factor out of the four, as the larger the system is, the more electricity it will produce. If you are looking at a typical installation, it is a 3.5kw system, and this tends to be around 12 panels. Alternatively, the 1kw domestic system is likely to only be two panels.

    Direction. This is the next most important factor. The direction in which your roof faces and its angles are more important than you might think. For optimum performance levels and efficiency, your panels should be facing south at an angle of 35 degrees.

    The area of your roof that has the solar panels installed should not be in the shade during the day. Allowing the panels to be in the sunlight all day will increase the amount of electricity that you are able to produce.

    Seasons. The time of year can also have an impact on efficiency and energy production. During the summertime, there are longer hours of daylight, so you will be able to produce a lot more power. However, it is also important to remember that solar panels actually work by capturing light as opposed to heat, so it will produce energy throughout the year.

    How Will You Know How Much Electricity Your Solar Panels Generate

    Your solar panels will come with a meter that will be placed in an accessible location within your home. This meter will record the amount of electricity being produced by your solar panels.

    Some solar brands are also rolling out online monitoring tools, which means youll be able to see how much power your solar panels are generating with the click of a button on your computer or phone.

    As solar panels require virtually no maintenance, it can be easy to forget about them once they’re installed on your roof. We’d recommend checking them regularly, however, to ensure they’re clean and in good condition.

    It’s worth monitoring your meter frequently too, to make sure they’re generating the expected amount of power. If your solar panels’ power output is particularly low, it could be a sign of a problem.

    Maximize Power Production From The Sun

    The electricity generated by a solar panel system is ruled by its rated power output. Yet, its dependent on other factors as well to best serve your energy usage. These include: panel efficiency, temperature sensitivity, shading, and the angle of your roof. A roofs angle, though, has less impact on panel performance than the direction it faces. Top production occurs when solar panels face south a tilt angle of 30° to 45°.5

    Additionally, available sunlight varies by location. This brief equation shows how sunlight and a solar panels specifications turn into the amount of power generated.

    Lets say on a good day, you average 5 hours of direct sunlight. Multiply 5 hours of sunlight x 290 watts from a solar panel = 1,450 watts or roughly 1.5 kilowatt hours per day. Thats about 500-550 kilowatt hours of energy per year from each panel on your roof.4 How does that compare to your annual energy usage?
