Just To Confuse You More, 3D Solar Panel Technology Provides a Smarter Solar Energy Solution.
If you haven’t heard of 3D Solar technology, you’ll be staggered to hear that a research team from MIT have shown that a 3D Solar Panel Tower (which you can build yourself) can generate up to 20 times more power than normal roof-mounted 2D solar panels.
Furthermore, not only will you need less than a third of the number of regular solar panels which reduces the cost, but the structure will have a footprint of less than 2 square meters too.

How Many Solar Panels Do I Need?
Simply put, the higher your electricity consumption, the more solar panels you will need.
To determine the number of solar panels you need to power your home, and consequently the size of solar panel installation you’ll require, you need to determine the following.
- Size of your house
- Your monthly electricity usage
Once you have these figures you can consult the table below to get a good idea of the size of the solar installation you’ll require as well as the price.
How Many Solar Panels Do You Need For a 2Kw Solar System?
Firstly you will need to know the wattage of each of your solar panels which will be expressed in watts.
Let’s assume your solar panels are 250w each and that your inverter runs at around 95% efficiency.
Therefore, to account for the inverter’s efficiency of only 95%, this means that your solar system will need to have the capacity of 2105 watts (2000 watts/0.95) to produce 2000 watts.
A Watt is a unit of power and defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.
To achieve 2105 watts you would therefore need approximately nine solar panels of 250w each (2105/250=8.42).
Furthermore, there’s likely to be further power loss through the cables to the inverter and other less than ideal conditions which could reduce the overall efficiency of your solar power system to 85%.
This would mean that you would need 9 or 10 solar panels of 250w (2000/.85/250=9.41) each to ensure an output for your 2Kw solar system.
