How many solar panels to power a house? Ultimate Guide

The needs of the modern era have changed and the requirement for energy is continuously rising. In fact, the demand for electricity multiplies every year due to the intensive use of appliances. However, a similar need is exploited when it comes to the bills. The consumer has to pay whatever the rate is offered by the companies. However, there’s a solution that can miraculously reduce your energy bills forever. Solar panels are a one-of-a-kind optimal solution if you are tired of paying heavy bills. The summer is just starting and it is a perfect time for residential solar panel system installation. The consumption of electricity will boost up in a couple of months, that’s why to use this guide and develop a complete understanding before you choose to install solar panels.

Requirement analysis

The energy bills can be reduced considerably if you just look at your requirements before the selection of a solar panel. If you have a home that has only some basic appliances such as, refrigerator, television, microwave, etc. excluding HVAC or conventional air conditioner, then you’d need a relatively little investment for the solar panels as compared to a house located in a very hot place and requires a continuous supply of cool air. If you were thinking about residential solar panel systems how many solar panels to power a house now probably you understand where do you stand.

Energy generation per panel

The selection of solar panels is completely dependent on your needs and a couple of more factors. The more wattage you want to produce the higher would be the cost of the system. The panels come in various watt sizes, for example, the smallest size is about 3.5 kW that you can find in the market and you can go up to 15kW. Now, to tailor a solar panel system is a critical job because you need to combine multiple sizes of panels to produce your required energy. That’s why you might want to hire an expert to do it accurately. Because if you want to extend the capacity later and it falls out of the domain of a control unit, then it has to be replaced.

The need for space

Another big issue that people face often is space. Since solar panels have to be placed in a particular way they require ample space to fit in. If you are going to join lower capacity panels to generate the required wattage, then it would need greater space. For example, a 5kW system generally requires about 300 square feet to be installed if you use low-efficiency panels. If you choose to go along with a 15 kW panel, a similar requirement can be fulfilled with less number of panels and you would require about 220 square feet of space for that. So, take a look at the available space and then decide because low-efficiency plates are comparatively cheaper.

Appliance based analysis

The energy is required to run multiple appliances and every addition of appliances adds more load to the system. If your solar panel system isn’t strong enough to run multiple appliances, it would shut down or cause fluctuations and that can be dangerous for your appliances. In order to avoid a bad situation, it is important that you carry out an appliance-based analysis. You can start by listing all the appliances that you’d like to run on the system. A refrigerator requires about 600kW, an air conditioner needs 215 kW, an HVAC system 1000kW, and a keep counting. Finally, add up all the numbers and that would be the required capacity of your home.

Now that you have listed all the facts, you are ready to calculate the number of plates that you’d need to run a home on a solar panel system. Usually, the energy requirement of a household is about 1500 kW per month and it would need about 40-45 plates to develop a tailored solar panel solution. However, the number of plates is variable unless you have an invariable requirement. The number of plates also depends on the technical team developing your system. If you desire an economic system, then you might have to resort to a larger number of plates that would require greater installation space.
