# Can You Power Your Home With Solar Panels-Electrician Tips

Thinking of investing on solar power? Are you wondering can you power your home with solar panels? We can help answer that.

On average solar panels can be used to power your home. Knowing how many solar panels one needs is the key to the system being successful. You will need to divide your kwh usage for a year divided by the number of days in a year to get your daily production of solar needed. This is assuming you want no power bill.

The answer isn’t exactly the same for everyone so read on so that you can understand.

## 1.Can You Power Your Home With Solar Panel- Calculate The Number Of Solar Panels To Power A House

To calculate the number of the amount of solar power that you will need for your home. You will first need to look at your power bill. The question is can you power your home with solar panels? On your power bill you will have an annual kilowatt hours used. Most homes on average use anywhere between 10000 kWh and 14000 kWh per year.

You would take this number and divided by 365. This will give you the daily usage of kilowatt hours. Alternatively you can look on the side of your power bill and sometimes they will have it marked as your daily usage right on your power bill. Whatever your daily usage is you’ll need to divide that by five. So for example if your daily usage is 38 kWh. Divided by five. This would be 7.6 kWh or 7600 W.

Now to get into more of the math. Why do we use the number five?. The number five is the average amount of sunlight hours per year per day. So the more northern hemisphere it is as low as 3 and south of the equator it is as high as 8 however we will use five for this example. Five is the amount of sunlight hours in the run of the day over 365 day. This includes cloudy days rainy days snowy days etc. So this is why we use the number five. Again talking to our math or talking if we take W or 38 kW divided by five this would be 7.6 kW or 7600 Watts. Now 7600 watts is it decent size solar system.

The solar panel wattage size is based on per hour of production.

## 2.Can You Power Your Home With Solar Panel- Use Solar Panels To Eliminate Your Electric Bill

You can use solar panels to reduce your power bill. You can do this by using a process called net metering which is usually available by your local power utility. Net metering is when you sell back your excess of solar production to the grid. This will offset for days that you use more. Like cloudy days or rainy days.

At the end of your power bill cycle you should see a credit. However you will need to size properly to make sure that you have the right size system. You can use example above to size your system if you’d like to have a net zero power bill or no power bill at all. Some areas of the world will even let you produce more than what you use resulting in either a credit or a check back to you directly to the customer.

## 3.Can You Power Your Home With Solar Panels-Can You Use Solar Panels During A Power Outage?

There are two types of solar panel systems. A Grid tie system where you sell back. This prevents you from having any power when the power is out. It’s designed so it sells back to the grid when it is on as a safety precaution it must shut down when the grid goes out. So during a power loss or outage your solar system was shut down as well and will not be producing.

This is to make sure that no power is pushed back onto the grid for the safety of the utility and provider.

The other type system is where an off grid inverter takes a solar energy and converts it into household electricity. In this case you would have power during a power outage as this is a completely standalone system and you can use it to generate power.

These types of systems are good in areas where the grid is not accessible. In addition to that if you do have the grid and you choose to go this way you can still use the power from your solar system when the power is out. Just keep in mind you are a battery maintenance with this process with this type of system.

## 4.Can You Power Your Home With Solar Panels-Can You Live On Solar Power Alone?

As a whole you can live on solar energy alone. However you will need to make some lifestyle changes and some smart decisions. Realistically how much money do you really want to spend on solar to get you through the couple slow months per year.

When we mean the couple slow months we mean November, December and January when the sun is at its lowest in the sky. You may size the system correctly for most months of the year however for those few months it may be hard to produce energy.

The opposite end is it is if you size it correctly for the slow winter months then you have an abundance of way too much solar have way too much solar energy in the summer. You could sell this back if you were in the right area and can strike the right agreement with your power utility provider. However due to the upfront cost most people just size them for the main part of the year.

There’s a slow parts of the year they subsidize their solar with alternative fuel sources like natural gas or propane to run their fridge freezer stove dryer or any other major appliance that you may need to consider is a lot of electricity.

## 5. How Many Solar Panels Will I Need?

Using our example above to provide 7600 watts to electricity or 7.6 kW you would need to supply 7.6 kW of solar panels.

The average size solar panel is between 200 watts and 400 Watts. If you go with the largest 400 Watt solar panel this result in close to 19 panels on your roof. Also keep in mind that these panels are 4’ x 8’ in size. This results in 32 ft.² of roof space for each solar panel.

You will need to measure the structure or the roof were you planning to install the solar panels to see if 19 of these will fit. 19 solar panels at 32 ft.² or solar panel is a lot of square footage almost 620 square feet to be exact.

## 6. The Number Of Solar Panels To Run Off Grid

The number of solar panels to run off grid varies depending on your needs. Most people start out with a smaller solar systems and then add to it as they see fit. Most of the smaller off grid systems we have done or usually only about 5 kW. 5 kW or 5000 watts is a good starting point for your off grid solar project. Keep in mind that you’ll have to subsidize this with some form of natural gas or propane for things like your hot water, stove, etc.

Battery maintenance also comes in to play with off grid solar make sure that you have the proper amount of good quality batteries for your solar system. We tend to sell customers more batteries and need it for storage purposes especially with off the grid to help them make it through the cloudy days.

Solar production can be combined with other sources like hydroelectric power or wind power to charge the batteries. The heart of the system would be your batteries in your inverters sending power back to your house. The amount of solar panels varies depending on size. Usually 24 to 36 solar panels a smaller size 100 W or smaller or sufficient enough to get you started. The voltage on the solar panels is a little bit lower than grid tie as we usually do 48 Volt systems.

## 7. Complete Solar Power Kits For Homes

One can purchase a complete solar system off the Internet. There are majority of links on Amazon and eBay which you can purchase these from. Can you power your home with solar panels from the internet?These are usually small starter system just to get you in the market. A couple thousand watts is about all you’ll see if you get a grid tie system or if you get an off grid system.

With the grid tie system you can usually get the grid tie inverter included in the kit. Make sure the inverter is approved for your area, as an example CSA or UL as well as CE approvals. If you get into an off grid system it will most likely include the inverter in the online kit however the batteries usually come from a separate source due to the weight and it is harder to ship them.

In the solar kit you should also get a charge controller to regulate the power to your batteries and possibly some MC for connections for plug and play.

## 8. How Much Roof Space Do I Need

If you’re talking on grid or off grid solar in either case you will need a lot of space. You can simply take the physical dimensions of the panels and multiply them to get your square footage. Once you have that you can figure out the square footage of your roof to see how many panels you can fit on.

Note that you should only stick the solar panels on the south facing side of your roof. These are the angle to the sun solar panels are the most productive. Also check out to make sure you get the proper mounting racks so you get air clearance of at least 2 inches between the solar panels and the roof shingles or roof space. This is important to not overheat and cause issues with shortening roof life.

Prematurely replacing a roof can be a costly project you do not want to endure.

## 9.How To Calculate The Payback Period

Your payback. Would vary depending on the amount that you pay for the solar system installed. You must include labour costs in this and any necessary permits to have the equipment installed on your home. You would simply just take the total amount to have it installed divided by the power production. This will offset the cost of your power bill and let you know your payback. Here’s an example of a payback. Below.

Ricky has 10000 watts of solar a panels installed on his house. He paid \$20,000 dollars for them installed and running. He produces \$12.50 per day on average so this would be times 365 days per year for a total of \$4,562.50. But wait he uses \$3000.00 per year in power.

So \$4,562.50 minus \$3000.00 is \$1,562.50. If you take his \$20,000 he paid for them and divide it by his surplus back to the grid of \$1,562.50 this would equal out to a 13 year payback to have the system paid for.

## 10. Will They Be Worn Out After I Pay For Them?

Most solar panels generally have a warranty for up to 20 to 25 years. This warranty is a prorated as a percentage and runs out after the 25 years. Solar panels have a life expectancy of 35 to 40 years and sometimes even longer in the right conditions. Most likely they will not be worn out after you’re done paying for them. Especially if you have an aggressive payment plan to pay them off quickly.

## 11.Can you run a house entirely on solar power?

Solar power is a great way to power your home. In fact, on average solar panels can be used to power your home as long as you know how many solar panels you need.

First, you will need to divide your kwh usage for a year divided by the number of days in a year. This will give you the daily production of solar needed. This is assuming that you want no power bill.

If you’re looking to go completely off the grid and live without any assistance from the local power company, then it’s possible with enough solar panels and batteries to store all of your excess energy.

You’ll need to take into account how much power you use per day and the number of days in a year before figuring out how many solar panels are necessary. You’ll also need plenty of batteries for storing excess energy generated during peak hours when the sun is shining brightly and little energy generated during nighttime hours or cloudy weather conditions.

So if you’re serious about going completely off-grid but still want some access to electricity, then it’s possible with these calculations and some creative thinking about storage and usage levels.

## 12.Can we run AC with solar power?

Yes, solar panels are more than capable of running AC units. AC units typically use between 1-2kW of power per hour. If you had a set of six solar panels that produced 2kW each, then you would have the ability to run an AC unit for about 6 hours before you needed to recharge them with batteries or grid power.

## 13.How many solar panels does it take to power an air conditioner?

You’ll need at least four solar panels. This is because an air conditioner typically runs for 24 hours a day, 365 days a year.

If you want to grow your business, great search engine optimization (SEO) is a must. The challenge? Many small businesses don’t have the time, skills or expertise necessary to handle everything that comes with a solid SEO strategy. From keyword research to content evaluation, from page optimization to internal linking, it’s easy for companies to end up with a generic web presence that doesn’t inspire engagement or drive conversions.

In this piece, we’ll tackle key outsourcing operations—from how they can benefit your business—and why SEO can’t be entirely outsourced.

## 14.Why is my electric bill so high when I have solar panels?

Solar panels are an essential part of living off the grid. They provide long-term energy savings and help you to reduce your carbon footprint. But if you’re not careful about how many solar panels one needs, you could end up paying for more than you need.

So, what is the right number of solar panels? First, it’s important to know that solar panels can produce different amounts of electricity depending on where they are installed. For example, solar panels in Arizona will produce more power than those in Alaska because there are more sunny days in Arizona.

Your home’s electric usage is also a factor. If you have expensive electric rates or use a lot of electricity overall, then it may be best to invest in more panels than someone with cheaper rates or who uses less electricity.

The other important thing to know is how many days per year there are where your home will have no sun shining on it—for example, during fall and winter months when days are shorter. There are 365 days per year, but if your home has no sun during 100 of them then you would only need 100 solar panels to meet your power needs for the year!
