How Many Solar Panels Do You Need To Power a House?

Determining how many solar panels to power a house or premises is the first question that most solar panel buyers would ask. Most people who want to install solar panels on their premises wish to supplement their current energy needs with solar energy. The first step in determining the total energy consumption of your house is to calculate the total kilowatt-hours you need before you purchase more solar panels. Finding out the number of solar panels you require will largely depend on your energy consumption. If you consume 11,000-kilo watt-hour, you’ll proberly need to install 250-Watt solar panels. Using the low and high panel production ration, you should have 28 to 34 solar panels to cover your energy consumption. When you know the total energy consumption in your house, you can use that to calculate the energy that is required and number of solar panels needed.

One-kilowatt hour is 1000 watts used in one hour. Therefore, if you have 20 bulbs using 50 watts, having light in the house will last for one hour. In this context, you would have used 1kw. According to research, most homes use 800-1000 kilowatt-hour per month. The solar panel production ratio plays a crucial role in determining the efficacy of the solar panels. When you divide the production ratio of 1.31 (lowest) and 1.61 (highest) by 250-watt solar panel, you will be able to get the number of solar panels needed for your house or premises. The amount of power your solar energy system can produce depends on the amount sunshine in your area, the exposure ratio, efficiency and the make of the solar panels.

Look at your energy needs for the past six months and from there, you can analyze the information and know the type of solar panel you need. You can compile data from average annual energy and estimate the solar panels needed in your house or business premise. Average solar panels supplied in the market include 15, 10, and 5kw. A number of products can change the kilowatt-hour requirement depending on existing equipment and appliances. For example, if you are running an air conditioner in the backyard, energy consumption could increase drastically.

It is possible to install solar system and install more panels later when energy needs increase. The most pragmatic way is to size the system accurately based on expected purchases. It important that you plan ahead to avoid confusion in terms of failing power systems. When using a solar system, it is imperative that you know how much utility savings you can have.

How Many Panels to Power a House

a.      Look at your utility bill

The best way to calculate how many solar panels you require is to look at the utility bills. An energy-efficient house will consume less power. Depending on where you are located, the amount of daylight you receive per year will indicate the number of solar panels you will require. It is imperative that you consider the location and how much solar energy you can expect to get.

b.     Estimate amount of electricity used during daylight hours

Select a solar system that generates adequate energy

Select a solar system that generates adequate energy

Unless you have battery storage, the solar panels will be able to meet your electricity needs during the day. Unless you have subscribed to solar feed-in tariff, then your solar energy is worth most when you use it directly. The electricity generated from the solar panels will first flow through the appliances you are using at home and this will save you huge amount of money in utility bills. It is essential to note that if you have devices that use huge watt-hours, you can restrict their use during the day when the solar panel is working. On the other hand, devices or appliances that do not require much energy can be used at night. During daytime, solar panels generate enough solar energy can help you power your appliances. It is important that you estimate the percentage of the total electricity consumption and if you use 20-kilo watt-hours per day, then you should look for a solar panel that generates 7-kilo watt a day.

c.      Select a solar system that generates adequate energy

With average electricity at 15-kilo watt-hours, a third of the energy is utilized during the day and this means that you use 5-kilo watt-hours during the day. It is essential that when you purchase a solar panel, you take into consideration energy consumption during the day. You should avoid using electricity during the day and use it in-grid at night. The highest electricity consumption usually occurs outside peak solar production. Installing 3-kilo watt-hour energy would be too large for a house if you were exporting 50% of the energy. The day focus electricity pattern is geared towards homes that are occupied during the day. With appropriately sized solar system, you can use a significant portion of the solar energy and send very little to the grid.

d.     Consider battery storage

Not all solar systems provided in the market are equipped with a storage system. In most cases, the battery system is sold separately and you should consider purchasing solar panel system with high-energy battery. If you are interested in battery solar systems, there are important features you should consider.

e.      Take electricity consumption into your hands

For many households, installing a solar system is one way that could reduce huge utility bills. When installing a solar system to supplement your energy consumption, there are other features to consider. Consider the number of occupants in our house, and note the number of devices that are being used. Once you have control over energy consumption, then you can maximize your energy consumption. Moreover, you can change old devices for newer ones that are energy efficient and consume less power.

f.        Monitor the solar system’s productivity

The term ‘prosumer’ is a new concept in energy production and consumption. In this context, you are consuming energy and producing energy at the same time. You will use the solar system to subsidize high-energy costs. The rising cost of electricity is causing more people to shift to solar energy. If you want to install a solar system, it is essential that you understand all your energy needs and look for ways of harnessing renewable energy sources. You can use invertors to monitor your energy needs and make changes to your consumption pattern.

g.      How to get the most out of your solar panels

As energy experts recommend, you should understand all your energy needs before you install solar panels. Choose electrical equipment that are efficient in energy consumption. It is imperative to note that you should take electricity consumption into your hands and shut off all the devices that are not in use and monitor all unnecessary energy wastage while increasing power efficiency. It is recommended that you look for a certified installer for your solar panel system. You should look for solar panels that are durable, efficient and can produce energy at an optimal capacity. The number of solar panels you require in your house should largely depend on your energy needs and you should also seek advice from energy experts to optimize your solar system.
