To determine how many solar panels you need for your home, you first need to know what your goals are. Would you like to reduce your carbon footprint? Save as much as possible? Most people want to save money while minimizing their impact on the environment.
How Much Solar Power Do I Need
An easy way to answer the question “how many solar panels do I need” is to consult a professional solar installer who can provide you with a free solar assessment for your home.
How Much Electricity Does A Solar Panel Produce?
To determine your home’s average energy needs, look at past utility bills. You can calculate how many solar panels you need by multiplying your home’s hourly energy needs by the peak hours of sunlight in your area and dividing by the panel’s wattage. Note that solar radiation on your roof and factors such as roof size and battery storage also play a role.
When you work with Solynta Energy, our solar experts do all of the calculations for you. But to give you an idea of how many solar panels are needed for the average home (or your home in particular), here are some sample questions a solar professional could use to find out:
View your electricity bill for average consumption. Search for “kilowatt-hours (or kWh) used” or something similar, then note the time period represented (usually 30 days). If your bill doesn’t show the kilowatt-hours used, find the start and end of the meter readings and subtract the previous reading from the most recent.
However, for our calculations, you need daily and hourly usage. So if your bill doesn’t show a daily average, simply divide the monthly or yearly average by 30 or 365 days, respectively, and then again by 24 to find your hourly average electricity consumption. Your answer is in kilowatt hours (kWh). (And in case you’re wondering, a kilowatt hour is how much electricity you’re using at any given time multiplied by the total time the electricity has been used.)

Your average daily energy consumption is your target daily average to calculate your daily needs. This is the number of kilowatt hours that your solar system must produce if you want to cover 100 percent of your energy requirements.
It is important to remember that solar panels do not always operate at peak efficiency. For example, weather conditions can temporarily reduce the efficiency of your system. So experts recommend adding a 25 percent “cushion” to your target daily average to ensure you’re generating as much clean energy as you need.
The peak hours of sunlight in your particular location directly affect the energy you can expect from your home solar system. For example, if you live in Lagos, you can expect to get more peak hours of sunshine than if you live in Bayelsa. That doesn’t mean the homeowner in Bayelsa can’t bet on solar energy; It just means the homeowner needs more panels.
Now multiply your hourly consumption (see question #1) by 1,000 to convert your hourly power generation needs in watts. Divide your average hourly wattage requirement by the number of daily peak hours of sunlight for your area. This will give you the amount of energy your modules need every hour.

This is where the quality of the solar panel makes the difference. Not all solar panels are the same. Photovoltaic (PV) solar panels (typically used in residential buildings) have wattages ranging from about 150 watts to 370 watts per panel, depending on panel size, efficiency (how well the panel can generate electricity – converting sunlight into energy) and cell technology.
Because of these huge differences in quality and efficiency, it’s difficult to make generalizations about which solar panels are right for you or how many you need for your home. The key takeaway is that the more efficient the panels are, the more wattage they can produce and the less you need on your roof to get the same power output. Conventional solar panels typically generate around 250 watts per panel with varying degrees of efficiency
To determine how many solar panels you need, divide your home’s hourly wattage requirement by the solar panel wattage to calculate the total number of panels needed.
If you have a small or oddly shaped roof, the size and number of solar panels are important considerations. With a large usable roof area, you may be able to sacrifice some efficiency and buy more panels (at a lower cost per panel) to meet your target energy yield. However, if your available roof space is limited or partially shaded, using smaller, high-efficiency panels may be the best long-term route to getting the most output possible, ultimately saving you a lot of money.

Knowing the answers to the above questions will give you an idea of the ideal number of panels for your power generation needs – or at least a realistic range. Next, a professional installer should review your roof architecture, sun angle, and other factors to see if and how you can physically arrange the right number of modules on your roof to meet your daily energy production goals.
First, check out our no deposit solar plans that can help you size the solar home systems you may need to power your home. to choose the right system that fits your lifestyle and budget. The easiest way to find out how much solar power you need is to do an energy audit. An energy rating is simply an assessment of how much energy you are currently using and a calculation of how much solar power generation is required to meet the needs of your home or business.
Energy consumption varies depending on the season, number of people living and lifestyle. To find out how much useful energy you are using, first collect your monthly electricity bills from the past year and note where the kilowatt hours or kWh consumed are listed. Most utility bills include the current month, past 12 months, and average daily kilowatt-hours used by the home or business. Using the information on the electricity bills, calculate the annual kWh consumed over the last 12 months. Note the monthly difference to understand your high and low consumption throughout the year.
When your home or business is connected to the grid, the amount of solar energy required varies between 50% and 100% of the kWh used annually. The percentage of the electricity bill that can be offset usually depends on the available space and the budget of the PV system. In grid-tied systems, solar panels typically generate more electricity than a household or business needs during the day. Excess electricity generated by the system is sent back to the grid, causing your utility meter to spin backwards. The energy supplier credits the additional electricity to your account. This process is known as net metering.

For off-grid systems, a more accurate calculation is required to determine the required energy load in AC kWh. This calculation uses information about each device that uses energy – how much power it uses, how long and how often it is switched on.
The power consumption of each device is recorded in watts. To calculate the power consumption of a device over time, multiply the power consumption times the hours of use. For example, if you have a 75 watt light bulb that is lit for 1 hour, it will use 75 watts or 0.075 kWh.
Enter your annual kWh from the electricity bill or the off-grid load estimate with the solar power calculator. Next, enter the daily daylight hours for your location by checking the solar energy map. Finally, enter the percentage of your electricity bill that you want to offset with your solar PV system. Calculate these three factors to determine the required DC wattage.
Once you determine the amount of power you need in relation to your location, you can choose a PV system that suits your lifestyle and budget. Remember that there is no rule that you have to compensate 100% of your current energy consumption. You pay it furiously knowing you’re sending more money down the drain. What’s worse, every year electricity prices rise, leaving you less money to spend on what’s important – your family.
