Hello! I welcome you on the board. we'll talk about the Solar Panels and it wattage to choose the solar panel according to the need of time. The performance and efficiency of a home power plant directly depend on the correct choice of solar panel characteristics. Innovative technology has made it possible to create a record 400 watt solar panel, which is currently the most efficient and economical. To determine the number and capacity of solar panels, it is necessary to accurately calculate the total energy consumption and choose the right type of panel.
Choose the Type
To determine the number and capacity of solar panels, it is necessary to accurately calculate the total energy consumption and choose the right type of panel. There are 2 main types of solar panels:
MonoCrystalline panels have great performance but only work when exposed to sunlight at an angle of 90 degrees. It is more efficient to install them in large solar power plants, where high output is important.
Polycrystalline panels work at any angle of inclination of the sun but have lower productivity. This type of module is more suitable for installation at home since they have a lower automatic start threshold.
Define the Brand
If it is important to you that your solar panel works efficiently and for a long time, take a closer look at the manufacturer's brand. Choosing the right company will provide you with excellent product quality.
It is best to choose from the "Tier1" list. Here are the top manufacturers from all over the world. As of 2020, the leading companies were:
- Check data on meter readings (less accurate)
- Independently calculate all electrical appliances, their power, and operating time. This way, you can get the most accurate result.
Follow the FormulaThe formula for calculating the power of a solar panel looks like this: W = k*Pw*E.
- Where «k» is a fixed index – 0,5 in the summer period, and 0,7 in the winter period
- Pw – the power of a battery;
- E – solar radiation index for the selected period
