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.

How Many Solar Panels to Power a House

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.

Certain materials are known to produce electricity with light. This process is called photovoltaic effect. Solar panels utilize this principle to convert sunlight into direct current or DC electrical energy. For sunlight to be converted into usable alternating current, an invertor is needed. An inverter converts direct current into alternating current. Any excess energy can be added to the electrical grid or fed into a battery storage system for use later. Solar panels work well when they are facing the sun directly. This works best for solar panels to convert sunlight into useful electricity. The effectiveness of solar panels depends on where you live and the prevailing weather conditions.

Modules, Cells, Arrays and Panels

In most cases, solar panels are made of silicon. It is important to note that solar panels could also be referred as modules and each panel is made of several solar cells that are connected together and sandwiched between backing plate and protective glass. Various materials are used in the manufacture of solar panels. Monocystalline panels are characterized by black color and are known to have a higher efficiency than polycrystalline or multi-crystalline panels. In most cases, polycrystalline solar panels are dark blue in color and have better temperature tolerance compared to other solar panels in the market. The main difference lies in the manufacturing process where silicon is utilized and it is converted into essential materials that could be used to produce energy from the sun. Interdigitated back contact solar panels are a variation of the standard solar panels.

Interdigitated back contact solar panels have higher efficiency because their electrical components are located on the back of the solar panels. In essence, since the electrical components do not come into contact with any metals, there is no loss of power. A new concept in solar panel manufacturing is thin film. In this process, thin photovoltaic materials such as cadmium telluride and amorphous silicon are used on glass as the base plate. This technology has evolved over time and promises to supply alternativeand better forms of energy than conventional energy. They are more efficient than regular solar panels placed on the roof of buildings and they could be used to generate power as an alternative to non-renewable sources such as coal. Solar panels can be used in small or large applications – from garden lamps, solar powered calculators to buildings integrated with PV systems.

What Is Solar Panel Efficiency?

This is a measure of the solar panel’s output in watts compared to its surface area. In essence, a higher efficiency means you can get more power from the solar panel. However, in situations where there is more roof space, then it is essential that you buy cheaper solar panels that have lower efficiency but yield more power in the end. As much as solar panels are made to be installed on the roofs, they become less efficient because of the photovoltaic effect or when temperature rises. In some cases, you may get less power from the panels on a very hot day (as high as 40 degree Celsius) compared to a normal day where operating temperature could be 25 degree Celsius. Some solar panels are known to have better temperature tolerance than other panels. In this context, you should look for solar panels with a lower temperature coefficient.

Installing solar panels in the right direction for optimal heat production capacity is crucial because it alleviates the need to look for aeration on the panels. In essence, solar panels should have good aeration for it to function optimally. You should choose the right installer to avoid complications that could affect the amount of energy generated. The installer should be eligible for installation, equipped with small-scale technology certificates as well as a systems accredited installer. It is important that you find an installer with an established record of installation solar panels and relevant experience. Another main aspect to look out for is whether the solar panels meet international standards.

Depending on your energy needs, the solar panel capacity that you require will vary and you can make some money by feeding excess electricity back to the grid. Unless you are able to secure a high feed in tariff to store surplus energy, then having extra batteries will help you conserve excess energy. Before purchasing solar panels, it is imperative that you calculate how much electricity you use in your home and the amount generated at peak hours. Once you have this useful information, you can determine what type of solar panels you need in your house or business premises. It is logical to choose panels with a higher rated output and this will depend on the space available on your roof. Manufacturer’s warranties of solar panels vary and in some cases, it could go up to 25 years. You should look for an installer who offers a guarantee of a certain period of time.

Solar panels available in the market vary in prices and performance. The price varies depending on the quality of components used and the system size. It is essential that you consider the kind of battery you will use to store excess energy. Once you have generated electricity during the day, you need a source to store the energy for use later in the night. There are some governments that offer incentives to solar energy users and it is crucial that you consult your local government to ascertain if you can be exempted from some taxes. The most common way of getting high quality solar panel is to allow an installer to sell you a panel or recommend one depending on your location and energy needs.

Feed in tariffs are rates that you are paid for electricity that you feed into the national grid or contribute to local networks. You can be paid for excess or surplus energy once your daily consumption is subtracted. Solar cells or photovoltaic cells are made of special materials in most semiconductors. When sunlight hits the solar cells, it is converted into electricity. Electrical conductors attached to the negative and positive side forms the electrical unit. Energy can be harnessed into electric current. It is important to note that solar panels do not need direct sunlight to function. However, it should be noted that its efficiency is boosted on sunny days where energy produced is optimal.

Different solar panels have different ways of harnessing energy and depending on the solar panel that you choose, you should get sufficient energy. Installing solar panels in your house will help reduce electricity bills by up to 60%. You can cushion yourself from rising utility bills by incorporating solar panels into the energy matrix. This is essential because it will reduce your electricity bills and initial installation costs will be covered. The feed in tariffs offered in most countries will help you recover installation costs as well as gain a better use for surplus energy. If your solar system works efficiently, then there is a high chance that you could sell power to the local network. Solar panels cuts carbon footprint. Since solar energy is a renewable source of energy, it reduces carbon emission by up to 25 tonnes during its lifetime. It is imperative to understand that solar panels do not release any kind of emission. In addition, solar panels are effective as they supply energy all year round, although they function optimally on sunny days.

Once solar panels are installed by a professional, there is minimal or no maintenance required. You only need to check whether trees or other buildings are blocking them and keep them clean for continued energy production. The essence of keeping solar panels tilted is to avoid deposition of dust and rainwater. Installing solar panels on the roof is better than on the floor because low maintenance is required. Solar panels can be used in remote areas where electricity grid has not been introduced and it is an affordable and effective solution for rural energy problem.
