Solar plates are very common nowadays to save you from electricity bills and produce electricity naturally from sunlight. There are several points to consider before installing your solar panels because it’s a long-term investment. One important point is to select the technology for solar panel installation to get better quality panels. Due to the low cost of solar energy, more and more homes and businesses are installing their own solar panels. You may significantly reduce your reliance on the grid by cutting back on energy use, and you can completely cut costs by converting to solar energy production.
No matter if you are a business or a household & going to opt for solar panel installation, here we will guide about the points to consider while switching to solar panels:
Measure the usage of your electricity
Calculate your previous utility bills to calculate the typical energy needs for your home. The number of solar panels you require can be determined by calculating the hourly energy needs of your household by the peak sunlight hours in your region, then dividing the result by the wattage of a panel. Establish a range by using examples of low-wattage (150W) and high-wattage (370W) systems (for instance, 17–42 panels to produce 11,000 KWH annually). Keep in mind that things like the size of the roof and the amount of battery storage will also be important.
You may measure your energy use with the aid of a competent solar installer. The amount of electricity you wish to produce with your solar system depends on this. You can decide how many solar panels to install and how much of your energy consumption can be covered by solar by knowing the average amount of energy you will be consuming. When you utilize energy is also crucial. Where to place your solar panels is important in order to make your panel produce more electricity.
Select the right Technology/brand
The amount of energy your system will produce will depend far more on the brand of solar panels you choose. There are numerous varieties of solar technology available. In contrast to photovoltaic technology, solar thermal technology only allows you to heat water. Monocrystalline and polycrystalline silicon are the two basic alternatives in solar systems. Although polycrystalline and monocrystalline silicon panels can offer significantly higher efficiency, the numerous additional criteria, which are discussed below, typically outweigh the advantages of choosing monocrystalline over polycrystalline.
Inverters
The solar panels not only depend on solar panels, but also on inverters Through the usage of this device, the direct current (DC) generated by the solar panel is transformed into alternating current (AC), a more broadly applicable form of electricity. Two different kinds of inverters exist one String or Centralized inverter the second is a micro-inverter.
Centralized inverter/String inverter
This is the inverter that is most frequently used globally. It transforms all of the solar panels’ DC power centrally and is typically more affordable. This has the drawback of treating the solar panels like Christmas lights, which limits the entire system if one panel isn’t working properly. The solar installation can only produce as much electricity as its weakest panel, so if one is in the shade, the system as a whole will produce less.
Micro-inverter
This is slightly more expensive than a string inverter, but it has several benefits. The micro inverter is often installed on each individual solar panel, unlike the string inverter. Because of its greater tolerance for shade, a solar array that is partially shaded can produce more electricity.
Suitable direction
The sun is in the south of the sky if you live in the northern hemisphere. Consequently, solar panels can be installed on a south-facing roof for optimal sun exposure.
Solar panels work best in the southern hemisphere when installed on a roof that faces north.
A west-facing solar array, however, would be more practical if you use the majority of your energy in the evening rather than during the day, as is the case with most residences.
However, an east-facing direction would be ideal if you want more solar electricity generation in the mornings.
Solar panels facing east and west naturally produce less energy throughout the day than those facing the equator, but unless you intend to deploy.
Selecting the correct and suitable position is very important.
A well-experienced installer!
Last but not least, after becoming knowledgeable about the aforementioned subjects, it is crucial to select a reliable installer who will:
- Examine your particular circumstance
- suggest the most appropriate technology and installation to you.
- get the necessary licenses and documents
- installation should be done
- confirm that all connections are in place.
