How many solar panels are needed to run a house?

Panels have different wattages and sizes, so the number can fluctuate a bit. Typical panels used in residential systems tend to range from 275 to 375 watts. You’ll have to divide your system size (EX: 6300 watts) by the wattage of each panel that will be installed on it: 225W = 28 panels, 275W = 23 panels, 375W = 17 panels depending on usage needs.

Of course, these numbers will vary for everyone based on their energy use and preferences, but this should give an idea about what you might want to order when shopping around.

How do I know which solar panel is best?

Style matters. Ask yourself, “Do I want a sleek-looking panel that will be an eye-candy in my garden?” or “Do I want something more utilitarian to make sure it’s hidden away?” No matter what your preference is, you have a couple of different styles to choose from.

Panels come in two main styles: monocrystalline and polycrystalline. Monocrystalline panels are generally the most expensive option but they can produce up to 25% more energy than polycrystalline panels (depends on materials). Polycrystalline is much cheaper than its monocrystalline counterparts, but is less efficient.

However, I recommend 3 steps to consider which solar panel is best…

Solar panel efficiency

Solar panels are a great investment for many homeowners or businesses, but with so many options and no clear-cut #1 choice, there can be some confusion.

There is little agreement on exactly what the most efficient solar panel would look like because efficiency varies depending on factors such as climate location, roof type (shingles vs clay tile), how much shade your home gets from trees in summer months, etc., all of which will affect how well you’re able to produce electricity from your solar system. The average efficiencies range between 16% and 18%, while industry averages fall right at about 10%.


It’s no secret that the solar panel industry is booming, and it continues to grow. Many experts are predicting a future in which we will be relying on renewable energy sources as our main source of power for everyday needs, such as heating water or pumping gas at the local service station.

The only problem? As more people invest their time and money into this new technology, there becomes an increased need for information about how these panels work best. A more important factor than efficiency may very well be warrantying; either provided by manufacturers themselves or through third-party providers.


The most efficient panels may indeed cost more upfront, but they can save you money in the long run. When comparing efficiency to price point, make sure you take into account all aspects of both before making a purchase decision.

How many watts of solar do I need for my house?

Best Residential Solar Panels

Your home’s energy requirements will vary depending on where you live and how much sunlight your roof gets. This is a good way to calculate the number of solar panels necessary for your household, but there are a few other factors that come into play as well – such as battery storage size or whether or not the house has an attic space.

The average person needs 10,000 kWh per year to live. If you have low-wattage (150W) and high-wattage (370W) solar panels on your roof and the sun is shining brightly during that time of day when they are generating power then it will take between 17-42 panels for a house with an 8×10 foot window (or 2420 square feet) depending on the wattage used in each situation.

What Time of Day Are Solar Panels Most Efficient?

It varies by location – it’s better for some areas than others, depending on the specific conditions of the landscape and other factors.

The four panels that are most efficient as far as photosynthetically active radiation (PAR) go will be your south-facing panels, but you also want to make sure plenty of light reaches every panel to maintain a healthy spread of their energy production.

A good rule to start with is having patterns so that no more than 2/3rds of anyone array will face the same direction. Space them out at least 8 feet apart, and preferably 10 or 12 feet if you can manage it without too much difficulty.

The sun is usually directly overhead (90 degrees to the horizon) in the middle of summer, because it’s high in the sky, and its light rays are more direct at midday than they are at any other time of day. So on temperate latitudes like North America, that’s typically 11 am or 12noon.

From about December 21st until January 20th in most temperate countries the sun rises very close to due east so east-facing panels will be better angled for generating power during winter months than west-facing panels would have been during that same time period in summer.

Benefits of solar energy: pros to keep in mind

Solar energy has several benefits, such as the following:

  • You can significantly reduce or eliminate your monthly electric bills.
  • The addition of solar panels to your home will increase its value and curb spiking costs for utilities in the future.
  • Your house becomes power-generating property!

That’s right – while you’re paying back the loan on installing these systems, they are producing income that goes directly into YOUR pocket instead of lining some faceless corporation’s pockets with profits from people like YOU who need electricity to survive.

Solar energy is literally what it does already since we get charged so much more than companies should be able to charge when there’s no other competition but them!

Final Thoughts

We have discussed the 7 best residential solar panels. Why choose from these? We know that solar energy is a renewable resource that generates electricity. It’s possible to create clean, sustainable power and help the environment with solar panels.

Solar cells are an invention made by humans to generate electricity from the sunlight without using any fossil fuels or other polluting sources of energy.

The cells work like semiconductors, but they use light instead of electrons as their charge carriers; it’s also more efficient than traditional methods for generating electrical power.
