How Many Solar Panels Do I Need For My Business
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.
Do You Even Need Solar Panels
You can run inverters off solar panels, but are they necessary? The answer is no, but solar panels offer many benefits.
If your home is tied to the grid, you can run the inverter off the main power supply. You dont need solar panels or even batteries.
Grid tied solar systems shut down during a power outage for safety reasons. If you want access to solar power during a blackout, you need a battery bank or solar array. You can also use them together. For instance you can charge the batteries with the solar panels and use the batteries to power the inverter.
If you are off grid, you can run the inverter entirely from a battery bank. Of course the batteries must have enough power to run the inverter.
You need a 300ah battery minimum to start the inverter, and that will run the system for an hour only. You need another battery or solar array to recharge it. In the meantime you must have another power source to keep the inverter going.
The point is, you can use an inverter without solar panels. But there are many reasons why you should. For one, it is an effective battery charger. Second, it is cheaper in the long run to use a solar array than keep paying monthly energy bills. Off grid systems can also use a combination of solar panels, batteries and even a generator to power inverters.
How Many Solar Panels Are Needed To Power An Average House
Here is a link to an article that looks at the average number of solar panels required to power the average home in each state.

Power Consumption Vs Usage
There is a big difference between power consumption based on where you live, housing types, and how often you use and charge electrical devices. According to the US Energy Information Administration, on average, an American household uses 11,000 kilowatt-hours per year.
A 100-watt solar panel can be used to charge a variety of small devices. This could be charging a laptop for a few hours each day, depending on its wattage and your overall power consumption. Plus, it can, in ideal circumstances, power a light for up to 33 hours .
The advantage of a larger 400-watt solar panel is that you generally have a few days of reserve, depending on your usage and without any other sources of recharging. A 400-watt solar panel has the capability of powering an energy-efficient fridge, multiple small devices, such as phones, tablets, and laptops, and televisions up to 32 inches.
To discover more about powering your fridge with solar panels, read our helpful article on How Many Solar Panels Does It Take to Run a Refrigerator?
How Much Power Do Solar Systems With High Voltage Produce
Many people want a higher solar panel voltage because solar panels with higher voltages will produce the same power as solar panels that have a lower voltage, but fewer solar panels.
For example, you can use four 12-volt solar panels instead of using just two 24-volts to achieve the same amount of power.
That being said, there are some disadvantages when it comes to solar panel voltage.
For example, solar inverters need to be sized correctly for a solar system that is configured with solar panels wired in series and this means theyll usually cost more than a solar kit designed for lower voltages.
Additionally, there are safety concerns when it comes to wiring solar panels together as you have the potential of producing very high-voltage solar panel voltage.

How To Understand All The Numbers And Symbols
Figuring out how much power youre going to get from your solar panel is actually a lot simpler than you might think.
Solar panels measure the power they collect from the sun in Watts . Typically, domestic solar panels produce a power output of between 250 and 400 Watts. Kilowatt is just another name for 1,000 Watts. We measure the energy a solar panel produces in Kilowatt Hours . So if you have a 250 W solar panel that gets the equivalent of four hours of direct sunlight a day, it produces 1 kWh of energy .
And then if you multiply your average daily power output by 365 , then you have your annual solar power output. In the example I used above, the yearly energy production would be 365 kWh.
Heres that calculation again:
Solar Panel Power in Kilowatts x Average Sunlight Hours Per Day x 365 = Annual Power in Kilowatt Hours
And thats it for the math.
The problem I have with all of this is that these numbers dont mean much to me until I translate them into actual energy usage. Why dont we take a look at what these Kilowatt Hours of energy mean to you and your electricity bill?

Solar Power Production: How Much Energy Does A Solar Panel Produce
When talking about solar power production, we are merely speaking of the energy we get from converting the sunlight into electricity. The conversion can either be done through photovoltaics, indirectly through concentrated solar power or using both methods.
When deciding if you want to buy or lease your solar panels, you should understand how solar panel output works in advance.
The question of how much energy does a solar panel produce is a common one. Many people still cannot say exactly how much energy their solar panels provide.
Although it is always indicated on the panels, and you can always check. It is also essential to understand how to arrive at that amount.
Solar power production is not a distinct element. Rather, its a combination of various factors and elements. The resulting energy after the conversion of solar energy by the PV cells is what is referred to as solar panel electricity.
In this article, we will explore solar power production and help you understand how much energy does each solar panel produce. However, before we get into that, lets first look at factors that affect the amount of energy produced.
How Much Solar Power Is Needed To Run An Appliance
Residential solar panels are the best way to save money on your power bill. While we can explain watt solar panel energy numbers all day, it makes it easier to understand if you know how much energy an appliance you use daily needs to run.
One of the best examples to use is a fridge. Everyone relies on their fridge, and its one of the most important appliances in a home.
The average 24 cubic feet fridge will run for 4 hours a day, using 250 watts per hour. This works out to be 1000 watts of power in a day or 1 kWh.
One solar panel is typically enough to provide power for the refrigerator. However, you will need a full solar panel system to get enough power output to provide power for the other appliances in your home.

How Much Do Solar Panels Cost On Average
The average cost of a solar panel is around $0.65 to more than $2 per watt for high-end models. That means an average 6 kW system will set you back up to $12,000, depending on the location. This is exclusive of installation costs, which can bump the price up by another $5,000 $10,000.
As a rule of thumb, PV systems in warmer locations are cheaper but require more panels, while the opposite is true with colder climates.
Fortunately, tax credits and incentives can cut solar panel installation costs and provide further savings throughout their lifespan.
How Much Power Do You Need From Your Solar Panels
The amount of power you need to generate depends on where youre installing your solar panels and how much electricity you use.
Energy usage is measured in kilowatt hours .
You can find out how much energy you need using your electricity bill or smart meter. It should give you average daily, weekly or monthly usage. On average, a British home uses around 3,800kWh per year of electricity, just over 10kWh per day.
If you were to estimate that there were 5 hours of sunlight on the average day in your region, this is just an example, then youd need a 2kw system i.e. 2kw x 5 hours = 10kWh per day.
Therefore, your solar panel system should aim to generate at least this amount. Again, check your electricity bill for a more accurate estimate or contact our team.

How Much Space Will My Solar Panels Require
The answer to this question depends on your answers to the above questions. The more energy you need to generate, the more panels youll need. The more panels you use, the more space they require.
You also need to factor in the capacity of each panel. For example, you would need more 250w solar panels to generate 2kw than you would 335w panels. Each panel measures roughly the same but their ability to deliver enough energy for your needs differs.
As an example, a 2kw system would require 8 x 250W panels. If each panel is roughly 1.6m x 1m you would need 12.8m2 on your roof to house them.
The same 2kw system with 335W solar panels would require 6 panels in total. These panel are slightly larger at 1.67m x 1m but would result in a smaller footprint of 10m2 due to the reduced number of solar panels required.
Remember this is an average. Our team will be able to give you exact figures on request.
