Solar energy is a renewable form of energy that is produced by solar arrays. Solar arrays are built from a group of solar panels, and the panels are basically boxes that hold arrays of solar cells. If you are thinking to use solar energy to power your home, you need to do some research about solar panel energy output in order to predict how many solar cells and panels you need to build to produce enough power for your home.
However, generally, each panel vary significantly They have different specifications and made of different materials. Here are the factors you need to consider:
1- The materials you use:
If you use cheap and weak materials the solar panels energy output will not be as efficient as the expensive and strong ones. There are three types of solar panels for home, they are the monocrystalline, the polycrystaline and the thin solar keluaran hk panels. The monocrystalline type is the most expensive and has the highest efficiency to collect sunlight and the least efficient is the thin type.
2- Your location: For instance if you live in Arizona, you get more solar radiation than someone who lives in the mid west.
3- Solar energy output is also affected by weather and seasonal variations. The angle of the sun to the solar panel changes with the time of day and seasonal variations. Cloudy and rainy days contribute to less effectiveness of the sunlight collection.
4- The size of the panels: The bigger the size, the more efficient it will be.
If you want to make the panels on your own, you need to do some research to approximate the quantity of the panels that you need. It is said that usually each of these cells can produce up to 0.5 volts, but as have been discussed above it depends on the quality of the material you use. If you need higher output, you can get solar cells that have higher amplitude. Use this formula to approximate the size of the panels you are going to need:
Amp x Volts= the amount of power in watts.
Using bigger cells may boost the solar panels energy output. Although you can produce more power with larger cells, the whole structure would be very large and heavy, so it might not be practical in most of the situations.
However, usually every panel has the specification that tells you the maximum output you can get out of the panel at given conditions, usually it is based on 1000 watt per square meter, but 90 % of the time you do not get that. It only gives an idea of what you will get but no real numbers.
