Why Is Direction So Important?

To maximize the amount of energy the solar panels collect, you want them to face the direction where the sun's rays are the strongest. This is why a solar panel system is normally installed facing south for installations in the Northern Hemisphere. If the project is being done in the Southern Hemisphere, install it facing north.

We know how the earth turns on its axis to provide us with endless hours of daylight in the summer and endless hours of darkness in the winter. How does this affect the solar panels?

Well, the sun is always in the same place in the sky. If you were to build a solar panel and let the earth do the rotating for you, you would get the hour of daylight and the hour of darkness anywhere on the planet. So, if your solar panels are facing south, you will get the greatest amount of energy in the middle of the day when the sun is the most powerful.

As the middle of the day is a time when many businesses and homeowners need the most energy, this makes a lot of sense.

Does The Angles Of The Solar Panels Matter?

While the angles of the solar panels might affect how much energy the solar system generates, it’s not always exactly clear how that works. Some panels can be tilted from 45 degrees to 90 degrees for a number of reasons, and the angling of the panels will not change how much energy you get from them.

Keeping the solar panels facing the sun all day is ideal. Most solar systems have brackets that help hold the system in place, so you can adjust them based on shade, your land, or your preference for the system to face a certain direction.

Angling the panels can potentially make the system generate more or less energy, depending on how and when the sun is moving in the sky.

The sun has a constantly changing path during the day. A solar panel that is angled to get the most of the midday sun, may not experience as much power at sunrise or sunset.

For example, if you are facing a south-facing solar panel, the panel will generate more energy during the time of day when the sun is directly overhead, rather than at sunrise or sunset. However, if your system faces west or east, there is less of a chance for the sun to be directly above the panel.

Why Should I Use Solar Power?

The sun is a source of free, renewable energy that has been supplying the Earth with heat and light for billions of years. In addition, it provides life-sustaining oxygen and water vapors to the atmosphere and the oceans.

So if you're looking for a clean, affordable, green renewable energy source for your home, you can't do any better than solar power.

Solar Panels are reliable, lowering utility costs and lowering your carbon footprint. They’re also easy to install in many locations without a permit and they come with a long-lasting 20-year power-warranty.

Solar power frees you from dependence on a utility company so you can be truly “off the grid.” It’s a great investment that has an expected lifetime of 30 years or more and will likely serve you after your progeny have moved out and settled down of their own.

How Much Does It Cost?

Firstly you need to know how much electricity do you consume to work out how many panels you need. The average UK household uses between 3,000kWh and 5,000kWh.

The price varies according to the size and where you purchase the panels. The price range is from £2,000 to £4,000 which is a one off payment. This is the payback period.

With an estimated 80% efficiency and .12p per kwh will cost you about £350 per year average.

So it will take you about 10 to 14 years to payback depending on the output, the efficiency and the size of the panels.

For the best return on your investment it is best to have at least 3 years of insolation and to ensure the panels face south.

Are There Different Types Of Solar Panels?

More than 55% of the total land area in the United States is directly suitable for solar power generation. Here, the solar radiation intercepted from the sun is about 1,000 watts-per-square-metre. To know about the different types of solar panels, continue reading.

Monocrystalline silicon panels: These panels consist of single slices of silicon. They are the most expensive type of solar panels. These solar power panels are highly efficient in generating power. Multicrystalline silicon panels: This panel consists of slices of silicon.

Amorphous silicon panels: This is yet another type of solar panels. Polycrystalline silicon panels: This panel is cheaper than the other panels. Thin-film P-N Junction silicon panels: These panels are adapted to the requirements of the consumer and the most efficient for space heating and cooling.

Can Anyone Use Solar Power Technology?

Is solar technology only for the wealthy? Absolutely not! In the United States, 45% of the population are renters. Many of these people cannot afford solar on their house roof. Given that solar can be used for businesses, how about having it on a mall, industrial building, or office complex? For these reasons, solar power technology is available for anyone.

The same goes for residential gardens. Are they for only the wealthy few? The truth is that whether you live in an expensive house or a mobile home home, solar is a great way to generate renewable energy.

In the Netherlands, an experimental program called the “Sunnovation” project installed solar panels in the gardens of over 1,200 low-income houses.

The program demonstrated that solar panels, although expensive, can be cheap or free if they are subsidized, and have as many advantages as those in wealthier neighborhoods.

You should be in a position to use solar powered technology whether you live in a small house, a shipping container, a mobile home, or a mansion.

How Many Solar Panels Do I Need For My House?

The amount of energy your panels will generate during the year in kilowatt-hours (kWh) is determined by the panel's solar energy output rating. Before purchasing solar panels, you need to know how many panels you will need to meet your energy needs.

Typically, you will need more panels if you are planning to use solar energy to power or operate appliances, electronics, or appliances which require a lot of energy consumption.

Sometimes, people think they have to use solar panels to power their entire home. However, this is not true.

The number of panels is based on how many hours are available to generate solar energy and how many hours are required to power your home.

You are advised to have a comprehensive view of your daily solar energy production.

How Is Solar Energy Collected?

Let’s start by explaining how solar panels are used to harness the sun’s energy. They absorb light energy and use it to create electricity. They are composed of photovoltaic material, which converts light energy into an electric current.

Solar panels are generally installed on the roof of your home and are secured to the surface with a mounting device.

Cables inside the panel transport the electricity to your home so you can use the energy to power household appliances, electronics, and other devices.

Mounting solar panels in an array on the ground is another common option. The array is either free-standing or on the roof of a dedicated building. It is composed of modules, each containing solar cells. The modules are wired together in series to form a series-parallel array.

The voltage produced by the array is lower than that produced by the modules in series, but the current is higher in a parallel array.

Installing a single panel is the most basic way to use solar power, but in order to harness enough electricity to be practical, you need to install several panels.

Installing multiple panels allows you to use electricity even on partly cloudy days when you don’t get enough sun for all your panels to work.

What Are The Impacts Of Solar Power?

Solar power saw a global growth of 29.5% in new installations in 2016, and the trend isn’t slowing down. In 2017, China and India will both likely see even more growth in solar energy use.

The biggest reason for the explosion in solar power is simple: money. For some people, the up-front costs of solar panels at their home, along with the installation costs, are expensive. However, solar power is the most cost-efficient form of renewable energy. In fact, according to a report conducted by the Department of Energy, the average homeowner who swears by solar could make their upfront costs back in one to two years.

Once the panels are paid off, then the homeowner gets to reap the rewards of having no energy bills.

Other benefits of solar energy are:

  • Decrease In Pollution
  • Energy Independence
  • Other Environmental Benefits
  • Easier to Use than Conventional Power Sources
  • No Increased Safety Risks

Many experts feel that solar power is the key to providing energy to those who usually have a hard time finding and paying for it.

Is Owning A Solar Power Unit Worth It?

Even if we live in the warm climate area with the best of weather year round, we find many reasons to use a solar panel on our homes or on our RVs. Not only does it provide a healthy and inexpensive power alternative that is renewable, but these solar panels also decrease our carbon footprint, as well as help save money on our monthly electric bills. Plus, as the world demands less dependence on fossil fuels and moving towards renewable resources, the cost of renewable energy will be decreasing, while the cost of traditional energy alternatives will continue to be on the rise.

I've often pondered the question, “Should I buy solar panels for home?” It's a difficult question to answer because the decision relies heavily on a few things. The first, and most important, is determining what your power needs are, i.e. your energy consumption. You will need to research your preferred solar panel company and size up what types of panels work for your home, as well as what your consumption is since this will all directly impact how beneficial solar panels for home are to you. The following is a sampling of the relevant reasons you may want to pursue buying a home solar panel system.

Final Thoughts

As this article has demonstrated, there are many reasons to install solar panels. Unsurprisingly, they each make good financial sense, which is why they are popular. Also, solar energy doesn’t require a lot of gear to begin collecting. This makes them an ideal choice for the less prepared. Even if you don’t have a lot of gear, you can still start collecting energy for your home.

The most important reason for solar panels to face south is that they can collect more sunlight during the day. This makes them more efficient, which makes them great for the environment and great for your financial future.
