Solar power is one DIY energy resource more and more people are considering. They are looking for ways to cut energy costs, and harnessing the sun’s power seems like an obvious choice. But before you start adding solar cells to your home, it’s important to consider the building’s location.
Look at Sunlight
When thinking about adding solar energy to your home, the first factor to consider is the sun itself. It means knowing how much sunlight hits the region and your property. If you live in a higher altitude or desert area, this will be easier to achieve. For those individuals who live in other areas of the country, how bright the sun is at midday is something to watch.
What Type of Sun Is Required
If your house only sits in direct sunlight for a few hours a day, you may want to rethink solar energy for your house. The reason is because solar energy requires a certain amount of bright, full, shadow-free sunlight to create enough electricity to be worth the effort and expense. If it’s often cloudy, there may not be enough power available to harvest the energy and convert it into electricity.
Don’t Forget About Shade
There are times when we like shade, especially when we’re in it. However, solar panels aren’t so fond of shade because this lowers the voltage output. Even a small amount of shade will dramatically change the output of energy. While the sun is a powerful DIY energy source, the amount of available power depends on where your home is located.
It’s important to remember that day shadows will take place, especially later or earlier during the day. Those times shouldn’t be a concern because the sun remains at an awkward angle. This means power is limited anyway and isn’t really being generated. It’s more important to avoid shadows from 10 a.m. to 3 p.m., specifically during midday hours. This is when the sun should be directly over the building.
Angle Toward the Sun
Whenever you use the sun for a DIY energy source, the solar panels need to be put on mounts that are focused on the sun. When it’s angled toward the sun, it produces the most energy production. It also helps if the angle can be adjusted throughout the year, as light changes each season. Then make sure to maintain the solar panels, so you receive maximum DIY energy amounts.
Solar panel diagram is a great way to explain the wonderful modern invention that can supply virtually limitless power from the sun for homeowners. Understanding how this combination of chemistry and electronics works together can help you design the perfect solar power system for your home.
A solar panel is the perfect marriage of chemistry and electronics to provide free power from simple sunlight. Even though the solar cells that make up these solar panels were discovered over a century ago, they have only gained a wide popularity among homeowners in recent years as they have become less expensive and more durable than ever before. Modern versions of these solar panels can generate several times the power of older versions from the same exposure to sunlight. They are also able to generate this power for a decade or more and represent a very smart investment for most homes.
The Photovoltaic Effect
The basic operation of a solar panel design is based on a scientific principle known as the photovoltaic effect. This phenomenon occurs when certain materials are placed in direct sunlight and are able to produce a small current as a result. Originally the materials used in a typical solar panel design was fairly exotic and expensive, but over the years further testing has produced less expensive compounds that can produce even large amounts of current from sunlight. The most common material used in modern solar panel design is silicon that is grown into crystals. These crystals are electrically neutral when made, but are eventually combined with other chemicals like boron to give them a negative or positive charge. These crystals are then placed in close proximity to each other and set out into the sunlight.
Converting Photons to Electrons
Natural sunlight is comprised of photons and when these photons strike the negatively charged silicon crystals, they act like a solar hammer and knock a free electron loose from the outer ring of this silicon molecule. This electron is immediately attracted to the other positively charged silicon crystal and a small current results. Even though this current is tiny, this type of activity is happening all over the surface of the crystal and collectively it is a fair amount of current. If enough of these individual solar cells are connected together inside of a solar panel, the overall energy production can be substantial.
Improving Solar Panel Efficiency
The science behind improving modern solar panel design is concentrating on improving the efficiency of these panels even more. Even though most modern solar panels are better than 16% efficient, this is still lower than most experts hope this technology can provide. By increasing the efficiency of these solar panels even further, they can supply even more power from these home solar power systems and increase their adoption even further among homeowners.
Modern Panels Are More Adaptable
The modern solar panel design also allows these newer models to generate a larger amount of power from less than perfect sunlight. Older systems could not convert the weaker sunlight found at sunrise and sunset and as a result they were dormant for most of the day. These newer solar panels for homes can utilize this weaker sunlight, and by converting it can generate even more power in a given day for your home. The cumulative effect of generating more power from bright sunlight and converting more of the sunlight that strikes them to useful energy is a result of decades of research that enables a modern solar panel design to be the most efficient ever built.
