The sun gives a huge amount of energy to the earth on an hourly basis and it stands to reason that solar energy can for sure power an entire house. So let us take a look into how this all happens and how van you make estimated solar calculations at home.
How does solar energy work?
Solar panels work by capturing particles of light or photons. These photons break electrons free from their atoms, knocking them apart and can generate what we know of as the flow of electricity.
Although, this statement can sound complicated at some degrees that are based on that how much science you remember from your high school and the main takeaway is that the sunlight is converted to energy by a seemingly complex but simple process that involves capturing the sun energy and then turning into electricity. And once the energy is generated, it is used to power products or devices and homes.
Can you run your whole house on solar power?
The answer to this question is yes that you can run a whole house completely on solar power. In a country like India where you receive a huge amount of sunlight throughout the year and it is also convenient to have a residential solar system. If you are planning to go completely solar then it can reap good benefits but there can also be some potential drawbacks that come along with it.
But the best part about generating electricity through a solar system is that it is completely free of any cost, only the initial investment is there that set up the solar system can be a little high in cost is depending upon your requirements. Solar power is quite efficient and it is also free of pollution. But you should also consider that there are chances of bad weather that may cause a problem to your plans.

How many solar panels does it take to run a house off the grid?
If you are in search to answer this question then I am sure that you are thinking about adding a solar system to your house. Many homeowners are already recognizing the benefits of the solar systems. If you are considering having solar panels installed in your house but you are not sure that where to start then you are in the right place. So I am going to discuss the details of that how many solar panels you may need for your house.
To find out that how many solar panels you will need for your house that you need to consider each and everything that uses power in your house. You should take a look at your utility bill that also helps you to give a good idea of how many solar panels you might need for your house.
How many watts do you use?
When you are looking at your utility bill then you will be able to see kilowatt-hours or KWh. Kilo- watt hours for houses can vary that depends on location that you are living.
A house in the south is more likely to have massive amounts of energy from air conditioner units. You must know about the average daily energy usage that will help you to calculate your solar needs. And once you have your usage details then you can look at how much wattage you will need to be able to run every electric product in your house.
Peak Sunlight Hours
You should keep in mind that solar panels can only work when they are in direct connection with sunlight. But after the sun is no longer shining down on them directly, then they are not producing energy.
Only peak sunlight hours are the time when your solar panels are in direct sunlight. All this is depending on your location and your peak sunlight hours also can vary. You can calculate your solar panel’s need by simply multiply your house hourly energy usage by the peak sunlight hours your house has and then you have to divide that by a solar panels wattage. You can also do this by using both high and low wattage panels to know about a range of what you might need.
Solar Panels you need for a 1500 square feet house
On average, a house is usually 1500 square feet in size and with a house of this size the electric bill comes in around $100 per month. If you want to cover the electricity for this house you would need an estimated 16 to 18 solar panels.
Let us understand with an example like a fridge may be rated for 250 watts and runs for 4 hours per day then it is 250 watts*4 = 1000W. A 1k watt is equal to 1kWh of energy per day. Of course, this is a general estimate and eclectic usage, sunlight hours, location and the type of panels that you have chosen could change this amount.
Types of solar panel systems
There are 4 popular types of solar panels you can install in your house –
- Solar Shingles
- Monocrystalline Solar Panels
- Polycrystalline Solar Panels
- Thin Film Solar Panels

Solar Roof Shingles
Solar Roof Shingles is the newest solar panels option is the growing trend. They are the modern answer to having a beautiful roof. Not only this but they also offer the added benefit of equipping your house with a solar energy system.
Solar shingles are durable and also protect your roof and home. Each solar shingle installed can produce 15 to 67 watts of solar energy but they can also withstand about any weather elements. You must that the cost of install solar shingles would be more than installing any other standard asphalt shingles.
Monocrystalline Solar Panels
Solar panels are made up of crystalline cells. Monocrystalline Solar Panels Cells tend to get higher levels of efficiency because they are made up of pure silicon. They are uniform in color and their cylindrical shape also helps to achieve higher efficiency. They are durable and they often come with long warranties.
Polycrystalline Solar Panels
It is the type of solar panels that were developed first and these cells can be recognized within a solar panel for their rectangular shape that is created when silicon is melted and poured into a mold.
Polycrystalline cells are not as heat-tolerant or efficient as monocrystalline cells but they are cheap in price than monocrystalline cells. Polycrystalline cells do not generate as much electricity from the sun and can affect some factors like the amount of electricity you can sell from solar energy.
Thin Film Solar Panels
Thin Film Solar Panels are a newer type of solar panel but they are less frequently used for residential purposes. They are tend to be less efficient than crystalline solar panels and they require a lot of roof space.
They tend to degrade quickly so many companies may offer shorter warranties. Thin Film is also inexpensive and more flexible as compared to crystalline solar cells. But you should know that solar manufacturing is a very competitive field and researchers keep coming up with new ways to make solar cells more efficient. Some of the latest technologies that are used in solar panels are dyes, plastics, inks and mirrors.
Can solar panels power a house during a power outage?
Solar panels alone would not work during a power outage but they can when paired with solar battery storage. Let us see that how solar battery storage keeps your solar system working when an outage with renewable, reliable solar power and that is the reason that why we need clean energy now more than ever.
Power through blackouts with a reliable, clean solar battery and take control of your energy storage. This can be done by diverting the excess solar energy so that your solar panels create to your battery and backup panel, then you can power the essential appliances of your house and the most important rooms in your house. A generator can also offer a temporary solution in the face of a blackout but it runs on dirty fossil fuels and can be troublesome and at worst dangerous.
But a Brightbox can make energy independence safe hassle-free and simple. You are also the freedom to choose what and how much you want to backup in case of power outage. Brightbox is more than just solar battery storage and it is a holistic service that gave the power in your hands. Battery storage can also rescue the power grid and if we do not start using some good sources of renewable energies such as solar energy and wind energy the sometimes blackout and power outrages could cause catastrophic damage. Batteries store excess power from your solar panels, with the use of a Brightbix you can generate, manage and store renewable power from the sun on your terms and condition. Brightbox can allow you to store the generated electricity and you can use it when you need it the most.
How do I run my house on solar power?
Solar power is a free source of energy after the only initial investment of setting up the whole system. Solar power is efficient and free of pollution. If you want to stay on the grid or traditional electric system then you can still use a traditional utility-provided power in situations where you can not make plenty of power or do not have any power stored. Our goal is often to eliminate the need for fossil fuel but this option might be good for those who are hesitant to leap.
The terminology may also be off- putting since we know about the word going to grid that is also associated with some tax dodgers and serial killers and the rest assured as a wholehearted solar theme that is completely wholesome. If you want to run your house completely on solar power you need a considerable amount of financial, mental and emotional investment. The infrastructure is a little bit more complicated, the calculations also are more precise and a mistake can leave you without enough juice to get by.
