Solar Power Wikipedia
Next we will talk about some basic concepts about solar energy, which you can find in solar power wikipedia inexhaustible source of energy that is freely available to all mankind.
Solar energy Wikipedia: What is solar energy?
Solar energy is energy from the sun in the form of heat and light. Solar energy can be converted into solar energy. This is done, among other things, by using solar panels , a solar boiler, a solar tower, or by making passive use of the sun’s rays.
How does solar energy work? according to solar power wikipedia
The sun sends a large amount of energy and heat towards the earth. You can collect this energy with solar panels and then convert it into electricity. Solar panels consist of solar cells. These solar cells are made of a material that only conducts electricity when light hits it. When the sun shines, an electrical current is created between the positive charge at the top of the cell and the negative charge below. This is called direct current.
This current is then converted to alternating current using an inverter. This is the same type of power that comes from your electrical outlet. The inverter then sends the current to the electrical grid. The inverter also records the total performance of the solar panels.
Solar energy is sustainable
In solar power wikipedia you will find that solar energy (also called solar power) is infinitely available. In addition, when solar energy is used, hardly any substances harmful to the environment (such as CO2) are released. That is why solar energy is sustainable. Solar energy coincides with wind energy, tidal energy, hydraulic energy and biomass in the framework of renewable energy.
How can solar energy be harvested?
- Solar panels: With a solar panel (consisting of solar cells) solar energy can be converted into electricity.
- Solar water heater: A solar water heater uses the sun to heat water. In the Netherlands, the sun is bright enough for solar water heaters and solar panels to work.
- Solar tower: The solar tower is a kind of glass roof with a tower in the middle. The air under the glass heats up like in a greenhouse and wants to rise. The tower in the center draws in air, where air pressure along the way drives turbines that generate electricity.
Passive use of solar energy For example, use the heat of incoming sunlight without the need for devices. The use of passive solar energy can generate significant savings in gas. Some examples: Large windows on the south side and smaller windows on the north side of a house/building. Or adjust the furniture in the house during a renovation (a warm space like the living room on the south side and a (less used) bedroom on the north).
Solar cells in solar panels.
Today, most solar cells consist of 2 layers of silicon that are connected to each other with current conductors. When sunlight falls on silicon, electrons are released. These cause an electrical current through current conductors between the 2 layers. Solar energy is converted into usable energy by an inverter on the roof. Your meter box distributes electricity throughout the house.
Benefits of solar panels.
- Lower energy bill
Because your solar panels generate power, you use less energy. This will lower your energy bill.
- better for the environment
Solar energy is sustainable energy, no CO2 is released during power generation. If you choose solar panels, you make a positive contribution to the climate.
- Higher home value
By investing in solar panels, you are also ensuring that the value of your home increases. You will receive a higher energy label if you have purchased solar panels. This makes your house worth more.
Do your solar panels generate more energy than you use? In that case, you can return to the network the electricity that you do not use. This is called compensation.
- Low maintenance
You don’t really need to maintain the solar panels. The rain washes away the dirt that ends up on the solar panels. However, it is advisable to check solar panels once a year for damage.
Disadvantages of solar panels.
- The roof must be adequate
Some roofs are not suitable for solar panels. Your roof must meet certain requirements. For example, at least 10 meters of surface must be available and the panels must face south. Preferably at the optimal angle of 36 degrees.
- Great investment
Solar panels are not cheap. You will have to invest a lot of money in one go. Buying solar panels can easily cost several thousand euros. You usually get it back in 7 to 10 years. After this period you will get a profit.
- not enough power
The power generated by solar panels is usually not enough to power your entire home. As a result, you will still need power from the grid.
Solar panels are also profitable in the Netherlands
Solar panels also generate electricity when the sun cannot be seen directly. This makes solar power a good way to generate electricity in the Netherlands. Even daylight that comes through the clouds can be converted into electricity by solar panels. Admittedly, this produces less power than a clear blue sky where the sun shines full on the solar panels.
Use or store solar energy
As long as the sun’s rays reach the panels, solar energy can be used for anything. The electrical energy from solar panels can be stored in a battery. This requires a special charge controller. The electrical energy produced is sent, possibly through a device so that the energy is adequate for the receiver, to a battery or to the electrical network.
Purchase and profitability of solar panels
The price of solar panels has fallen considerably in recent years. Compared to 5 years ago, the price has been cut in half and more and more people are buying solar panels, partly due to the price reduction.
Due to continuous panel improvements, today’s solar panels produce more energy and therefore become more and more cost effective. Of course, it’s still a matter of: the more electricity you produce yourself, the less you have to pay on your energy bill.
Payback time of solar panels.
On average, solar panels pay for themselves after about 9 years. If you consider that the average useful life is 25 to 30 years, you will benefit from free energy for at least 16 years. Of course, the payback period depends on a number of factors, such as the position of the panels.
install solar panels
In order to generate as much energy as possible, it is important that the solar panels are in the optimal position towards the sun. If the installation of the panels is done quickly and imprecisely, the ceiling may be damaged or the panels may not be in the optimal position. Therefore, it is important that the installation of the solar panels is done with precision to get the most out of the panels.
No roof suitable for solar panels?
If you want to invest in solar panels but do not have a suitable roof to put the panels on, it is possible to invest in a solar panel project. In this way, you can become the owner of one or more panels and also produce green electricity. This saves you money and helps create a cleaner environment.
Solar panels will also generate power at times when you don’t use power yourself. Unfortunately, it is not possible to store energy. The energy you don’t use yourself is fed into the power grid and used by other people. If the energy record is correct, this energy will be deducted from your energy bill. In this way you always benefit from the energy generated by the panels. For this it is necessary to have a counter that can count backwards, a smart counter also works.
Pay attention when changing energy provider
If you want to change your energy supplier, it is advisable to take into account the fact that you have or want to buy solar panels. There is a difference between power providers regarding power compensation. See the different feed-in tariffs by energy provider.
