What solar panel do i need
If you’re thinking about going solar, you’ll definitely have quite a few questions, like how manyyou’ll need to power your property.
In general, the normal solar system for a house comprises 20 to 25 panels, but the actual number you’ll need will depend on various variables, including where you live, how much energy you regularly consume, and how much electricity your panels can create.
It can seem like a lot to contemplate, but it’s really straightforward when you break it down. Let’s look at three major criteria that decide how manys you need to power your home, as well as an example of how to assess the size of your system.
How many solar panels are required to power an average house?
The typical dwelling size in the US is 2500 square feet, which should logically correspond to the average energy demand of 11000kWh per year or 30kWh per day.
However, there are variances in home size from state to state and also in solar panel electricity production. This is because the sun’s energy, or irradiance, varies by geographic location – highly essential when evaluating the cost of a solar farm.
Factors that will impact the number of solar panels you need
Although the square footage of your building will be a portion of the final jigsaw, the quantity of panels you will require is ultimately determined by the following four factors:
- The amount of power you utilize
- Amount of everyday direct sunshine in your location
- The quantity of available roof space
- The kind of solar panel you pick
How much power do you use? We prefer to look at your most recent 6 to 12 months of energy consumption. Thanks to Net Metering, we can utilize this information to correctly scale your system to cover 100 percent of your annual demand in most circumstances.
Put it where the sun shines – The quantity of direct sunlight your roof gets will vary dependent on where you live and the time of year.
Not all roofs are created equal – The ideal roof has a 30° pitch and is facing straight south. Since that’s not always practical, a less than “perfect” roof may require more panels to provide the energy you need. The good news is solar panels are getting more and more efficient. These changes have made it more cost-effective to place panels on rooftops that face east/west and aren’t the optimum pitch.
Solar panels are not one-size-fits-all – The efficiency level of solar panels (the ratio of energy generated vs the energy input from the sun) varies. Efficiency levels have gone a long way during the previous decade. The panels we install have an efficiency of 16.6 percent to 21 percent.
Solar panels operate at maximum capacity when they can absorb the most possible sunlight. With more sunshine, each of your individual solar panels will generate more power. The location of your home isn’t something that you can change, but it’s important to recognize that your region plays a role.
