You have considered getting solar panels for your home, but what if they do not work the way you expect? This is a common fear among homeowners who are considering a residential solar installation but knowing the factors that influence the energy yield of photovoltaic panels will help clear our heads in order to make an informed decision.

Solar panels are an excellent way to be helpful to the environment, but what are some of the top factors that impact solar panel efficiency?

Location

Solar panels use sunlight to generate electricity, so they naturally follow better in areas that receive a higher amount of sunlight. Places located near the equator generally have more sunlight than those near the North and South poles.

We may assume that solar panels work more efficiently in hot weather since there’s plenty of sunlight, but solar panels actually perform poorer in warmer temperatures. Prolonged exposure to extremely high temperature will degrade solar cells, thus reducing the panels’ efficiency. High temperatures also reduce voltage and power because there is more resistance in the solar cells. Hotter materials will have a higher resistance rate. Any resistance can decrease the number of electrons that will pass through the circuit, and the energy production suffers. Between two locations with an equal amount of sunlight, solar panels will perform better in the one with cold weather than the one with hot weather.

 

The quality of your panels

As with any technology, there are various types of raw materials used for solar panels, and each will differ in quality. A colossal amount of the world’s photovoltaic cells are made of silicone, but there are various types of silicone that can be used. Generally, monocrystalline solar panels are the most efficient solar panel type since it is made using the highest quality but also the most expensive silicon in the market. Polycrystalline silicon is not as effective as monocrystalline but is considerably more affordable than the latter. Thin-film panels are relatively the least efficient of the three since a lot of space is required for these panels to generate sufficient energy.

Rooftop positiioned solar cellsRoof Orientation

Solar panels on roofs should be positioned in a manner that maximizes the amount of sunlight that hits the panel. In the United States these devices should generally face South for this reason. The pitch of your roof is an important factor that system designers take into account as well; the solar panels should be tilted into position to get the maximum amount of sunlight possible. Where the panels should face and what angle it should have will just depend on the location of your home.

Shade

Shade can significantly reduce a panel’s efficiency. The photovoltaic panels are composed of many interconnected solar cells; if a cell is covered with shade, the performance of the whole board is affected since the entire current flow will be hampered. If shade cannot be avoided, the solar installation company should carefully plan how to set up the solar panels in a way that the shade will not significantly slow down your energy production.

These factors, along with several others, affect solar panels’ efficiency. The key to having an efficient solar power system is careful planning. Every factor should be considered for maximum productivity, so study these factors carefully before installing solar panels for your home. And much like how air conditioners require louisville ac repair, expect to need to perform on-going maintenance on your solar installation.

Solar power has been the buzzword in the scientific community for some time now. It is almost considered as a miracle child – the renewable, clean energy source that people can actually use at home. It helps ordinary people do something about climate change.

However, before jumping ahead and buying some panels for your home, you need to carefully consider the pros and cons of using solar panels at home.

How do Solar Panels Work?

Before understanding the benefits and downsides of solar panels, we should first come to an understanding of how they work. The primary material of a solar panel is silicon, a semiconductor, and solar panels comprise of tiny photovoltaic cells that convert sunlight into electricity. When sunlight hits the silicon, the photovoltaic cells help the photons (which are the fundamental particles of visible light) to knock off electrons from atoms of the silicon. This process generates electricity. This proves to us that sunlight is absolutely needed for these devices to function.

Benefits of Using Solar Panels at Home

Now that we understand how they work, let’s learn more about how you will benefit if you install them on your property.

  • It will reduce your electricity bill.

For homeowners, any means of reducing our electricity bills would always be welcome. In some cases, depending on the amount of sunlight available in a location and the size of the system, the electricity bills are reduced by as much as half of the price. Simply put, any amount of electricity that you use produced by solar panels is deducted from the amount of electricity provided by electric companies. You will then rely less on the electric companies and their costly electricity for everyday use.

  • They are perfect for remote areas.

It can difficult to set up electric systems in desolate or remote areas, but solar panels can bridge this gap. As explained before, all that is needed for them to work is sunlight, so remote areas with plenty of sunlight will hugely benefit from this technology.

Practicing what we preach is the best way to teach our children the values that we want them to grow up with. Using solar panels at home shows our children that we care enough about the environment that we bought an entirely new technology just to save electricity. The love for the environment will stay with them as they grow old, and that in itself is a huge reward for us parents.

1. Costly to install

The initial investment is costly. It is estimated that average-sized systems between 4kW and 8kW will cost anywhere between $15,000 to $30,000. This includes the cost of solar panels, labor, the balance of systems, permits and inspection fees, and other operational costs. However, as noted earlier, the initial costs are compensated for by the reduced electric bills, so this can consider a wise investment.

2. Not compatible to some locations

Since solar panels depend on sunlight, those living near poles and have a little amount of sunlight will not experience the full potential of solar panels. On the other hand, those near the equator will enjoy a high volume of produced electricity.

These are crucial things to consider before installing solar panels for your home. Overall, solar panels present valuable benefits to the environment and to homeowners alike. With careful planning, installing solar panels at your home can produce significant changes in your family’s life.
