In the previous blog we had a brief about 5KW solar system design for a house while in this blog we will consider a 400 watt solar panels as a practical example:
If we are using 400 watt solar panels with an efficiency of 20%, we would need around 13 panels to achieve a total power output of 5.2 kW.The total wattage of the panels would be 13 x 400 = 5,200 watts, which is slightly higher than the 5 kW system we are aiming for. However, this is a good thing, as it will give us some extra capacity in case of any drop in efficiency due to weather or other factors.
Next, we need to consider the inverter. The inverter needs to have a capacity of at least 5 kW to handle the power generated by the panels. It's worth noting that many inverters are designed to handle a slightly higher wattage than their rated capacity, so you may be able to use a 5 kW inverter even with slightly higher wattage panels.
For the mounting system, the number of panels and their dimensions will need to be taken into account when designing the mounting structure. Depending on the roof or ground surface, you may need to use different types of mounting systems, such as a ballasted racking system for a flat roof or a ground-mounted system for uneven terrain.
Finally, you will also need a monitoring system to track the performance of your solar system and ensure that it is generating the expected amount of power.
Again, please note that this is a basic example, and the exact components required for your solar system will depend on your specific energy needs, location, and other factors. It's always best to consult with a professional solar installer to design and install a solar system that meets your specific requirements.
