How Many Solar Panels Do I Need To Power A 3000 Square Foot House

We know the average sized home requires 7924 solar watts with the average US irradiance of 5.3 peak sun hours/day, which equates to 3.17 watts per square foot.

Multiplying this number by 3000 square foot, we get 9510 watts of solar required.

9510 watts / 300 watts = 32 solar panels of 300 watts rating each

How Many Panels Will I Need For A 3kw System

The average solar panel is 250W, so to make up a 3kW system we will need to install 12 panels. 12 x 250W = 3kW

3kW solar system = 12 Panels or 20m2

Each panel is on average 160cm x 100cm which is 1.6m2 per panel. This means you will need about 20m2 of available roof space facing north to make a 3kW system available.

You should consider getting an installer out to have a look at your roof size and orientations to see if this will fit.

With todays technology, your local solar installer is able to look at Google maps to see your roof size and orientation. There will be no need for a site visit.

Solar Panel Output Per Square Metre

The most popular domestic solar panel system is 4 kW. This has 16 panels, with each one:

  • around 1.6 square metres in size
  • rated to produce roughly 265 watts of power

To work out the output per square metre, use this formula:

Number of panels x Capacity of solar panel system

Capacity ÷ Total size of system


  • 16 panels of 265 W each:
  • 16 x 265 = a capacity of 4,240 kW
  • Total size of the system
  • 4,240 ÷ 6 = 165 W per m2

The electric bill savings from a 3kW solar system varies widely from state to state. This is because your power bill savings depend on how much energy is produced and how much electricity costs.

For example, if your 3kW solar system generates 415 kWh a month in Florida, it will save you about $46 per month. A system installed in Massachusetts that produces 415 kWh would save a homeowner $79 per month.

The table below lays out estimates of how much a 3kW system can save in various states:

New York $550 – $875

The payback period for your solar panels, or the time it takes to pay the system off and get completely free electricity, depends on your state incentives.

Your payback period will be shorter if you live in an area with additional solar rebates like solar renewable energy credits . Find out what your estimated payback period is for a 3kW system in your state here.

A 4kW system is a suitable solution for the average-sized UK family because it can cover average power requirements and aid to cut power costs. It can also assist in generating renewable energy, reducing carbon emissions while increasing the value of your property.

Its critical to complete your homework before investing in solar panels. You must ensure that the system you select is appropriate for your energy needs. Its possible that if its the wrong size, it wont cover your electricity usage as well as youd planned.

Installing an energy efficient 4 kW system will save you money on electricity bills while also making your home more environmentally friendly and simplifying your life due to the systems low maintenance costs and long lifespan.

Furthermore, you can generate income through the Smart Export Guarantee if youre generating energy that is sufficient enough to be transferred back to the national grid.


How Do I Improve The Output Of My Solar Panels

There are 4 key factors that will determine just how much electricity you can create with solar panels for your property:

  • The size of the system is the most important factor of all. The typical domestic installation is a 3.5kW system, which is normally around 12 panels. A smaller 1kW domestic system is likely to be only 2 panels.
  • The direction that your roof faces and the angle of the roof comes next. For optimum performance, your panels will need to be on a 35-degree angle, facing south.
  • Having a roof that is not in the shade will increase the amount of electricity you are able to produce. Take a look at the handy table above, which shows you what output volume can be expected from a domestic solar installation.
  • The time of year will also have an impact. During longer daylight hours in the summer you will be able to produce proportionally more power. That said, its important to remember solar panels work from light not heat so will still produce energy all year round.

The Benefits Of Larger Systems

  • Economy of scale a 5kW system, for example, comprises just four more panels than a 4kW system. The extra labour cost in installing those panels is minimal. Scaffolding costs , where applicable, would be the same, and the slightly larger inverter will only be a few pounds extra.
  • Savings on the electricity bill will be higher this will particularly benefit high electricity users.
  • Non-optimal installations can still get high yields those properties with east and west facing roofs can generate as much electricity as those with a south facing roof, by using more panels on both sides of the roof.

    Historical values for irradiance can be found for your location on sites like GlobalSolarAtlas.info. The average irradiance value for the USA is 5.322 kWh/m2/day, so Ill use that value of peak-sun-hours for our calculation.

    How many solar panels how much solar do I need to power an average house in the USA?

    Using average US values, you can find the theroretical solar power output by dividing the daily kWh by the irradiance value in daily peak-sun-hours:

    Solar power required = 30000 watt-hours/5.3 peak-sun-hours = 5660 watts

    If 300 watt solar panels were used, the number of solar panels for the average US house would be:

    5660 watts / 300 watts = 18.86 solar panels

    However, all solar PV systems have losses of about 23%. This can be taken into account my multiplying the solar power required by 1.4:

    Adjusted solar output = 5660 x 1.4 = 7924 watts

    Using 300 watt solar panels, the actual number of solar panels needed would be:

    7924 watts / 300 watts = 26 solar panels

    Forget Single Solar Panelshow Much Energy Will Your Whole System Produce

    Knowing how much energy a single solar panel produces is all well and good, but more importantly, how much solar power can your roof generate? Lets do the math below:

    Take our example above, where youre getting an average of five hours of direct sunlight per day and using solar panels rated at 290 W. Lets say you install 30 of those premium solar panels on your roofthat nets you a 8,700 watt, or 8.7 kW solar panel system, near the average system size purchased on the EnergySage Marketplace. Multiply the five direct sunlight hours we estimated above by 8.7 kW, and we get approximately 43.5 kWh of electricity produced per day. And for one final conversion, if we multiply 43.5 by 365 days in a year, we get approximately 15,800 kWh of electricity produced in a full calendar year from a rooftop array of 30 premium, 290 W solar panels. Considering the average electricity use per year in the U.S. is around 10,600 kWh, thats probably more than enough to power your home on solar.

    This estimate is likely on the high end for most solar shoppers, and likely because of our estimate for the amount of sunlight the system will get . To learn more about average sun hours, check out our blog here, where we take a look at average sunlight per year by location.

    How To Tell How Much Electricity Is Being Generated

    4kW Solar Panel System -Everything You Need to Know | GreenMatch

    When you go to have your solar panels installed, they will come with a meter that is placed in an accessible location within your home. What this meter does is record the amount of electricity that is being produced by the solar system, as well as how much electricity they are exporting back to the National Grid. This then allows you to work out how much you will be paid by the Feed-in Tariff.

    Solar panel manufacturers are also starting to develop online apps for your smartphone that will allow you to access the performance levels of your solar panel. This can be done either via the app, or online from your computer.

    To get the most out of your solar panels and the electricity that is produced by them, you should ensure that you use your appliances during the day as much as possible. This is because it is during the day that the panels will be generating energy.

    You should also try to ensure that your home is as energy efficient as possible. This allows you to get the most out of your free energy. Try to use energy saving lightbulbs, and dont leave electronic devices on standby if you can help it, as these are all contributing factors to excessive energy consumption. Try, also, to only use the washing machine on a full load.
