Solar Power Facts | Solar alternative energy

Solar power facts tells us that we must adopt and use as much as we can this energy if we want to protect the earth and save the planet.

Solar Panel Funding-Sounds Like A Good Investment

As you already know, we can use solar energy to obtain both thermal energy (solar collectors) and electricity through solar panels (also known as photovoltaics, photovoltaic panels). These solar panels are made up of a large number of solar cells. The power of an individual solar cell itself is as low as 1 to 2 Wp (Watt peak) and as such they could not be widely applied. Therefore, these cells are connected in larger units, called solar modules or solar panels.

To get as much power as possible from the modules, they are connected in so-called photovoltaic panels, and the same in larger plants that have a capacity of several megawatts.

photovoltaic panels

Most of the manufactured solar panels are made of crystalline, polycrystalline or amorphous silicon in the form of a thin film.

Monocrystalline (single-crystal) solar panels – the fabrication process is expensive but they have good efficiency, 12-19%. They are more effective than polycrystalline ones when there is less sunlight. These are the longest-lasting panels, made of one crystal of pure silicon. They take up less space than other panel types.

Polycrystalline solar panels – production costs are lower, efficiency is 11-15%, and under diffuse radiation are more efficient. They are made up of more crystals, so the production process is cheaper. Larger surface area is required for their placement in relation to single crystal panels.

Amorphous solar panels – the latest technology with lower production costs and lower efficiency – 8-10%. They are made of very thin layers of amorphous silicon.

They require twice the area to produce the same amount of electricity as single crystalline or polycrystalline panels. They are more efficient at higher temperatures.

Lately it has been experimenting with Cadmium telluride (CdTe) photovoltaics  and organic solar cells.

Solar panels manage to use only part of the sun’s radiation and convert it to electricity.  Commercial solar panels have an efficiency of between 12 and 23%. It is a common misconception that the efficiency of a solar panel is a very important item, sometimes more efficient solar panels have a significantly higher cost and therefore do not justify the investment.

Currently the highest efficiency of solar panels is achieved in laboratory conditions and is approximately about 43%. The efficiency of solar panels is significant only if the building is limited by the roof or other surface where the solar panels are installed, so it is necessary to extract as much energy from as little surface as possible, if there is enough space to install the solar panels the efficiency is not so important.

Solar energy costs

Below we will explain some of the cost-related factors. For installation of solar panels and their cost-effectiveness.

Place of residence

People living in parts of the earth where most of the time is sunny have a higher advantage than people who settle in less sunny areas because their systems are able to generate more electricity. Their location at the very beginning puts them in a better position to enjoy and use sunlight.

Electricity, its cost varies from place to place. Those who live more contemporary times and have significantly higher electricity prices would probably think well before setting up a solar panel.

Installation costs necessary to set up a solar system

The bigger the system, the lower the cost. It is important to remember that many solar systems do not fully cover 100% load of electricity. In addition to lower electricity bills, there are other potential ways to cover the costs of PV systems for residents and corporations who want to upgrade and move to the solar world. Such reliefs include: state subsidies and partial covering of the costs known as Solar Panel Funding, discounts from companies offering these products, and other forms of financing.

Photovoltaic solar power supply to the house

What should you do to obtain solar energy for your home?

Although we have argued that installing solar panels is not very difficult to perform, it does not mean that this process does not requires an expert with instructions and certainly with no experience in installing solar systems. One of the most important things when installing a solar panel is the roof structure itself. Not every roof has a good angle so that a solar panel can be installed to maximize the use of solar energy.

Meteorological data provide an average monthly level of solar energy in different geographical regions.Rainfall, cloudy days, humidity and all other factors are taken into account.  It should be designed in the worst month, so that there will be enough electricity throughout the year. With all that data and information about your average household consumption, you can know how much PV you would need.

No matter what difficulties someone may still face when installing a solar panel, but with the improvement of technology the costs of using it are reduced.
