How many kw of solar panels do i need.

Assuming you are going to choose standard efficiency solar panels here are the most common sizes for residential solar systems and their kwh production potential to give you an idea. How many solar panels do you need for 1000 kwh per month. The amount of power kwh your solar energy system can produce depends on the number of solar panels that can absorb solar energy and convert it into electricity. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel.

Solar panels for households typically come in the standard dimensions of 1 70m x 1 00m that s around 1 7m2 for every panel installed however the wattage output w of the panels will likely vary between 250w and 360w for a more efficient module. A typical american home will need 14 36 solar panels to cover their power bill and at least 227 square feet of rooftop space to accommodate the solar panels. However solar power is an effective solution to reduce energy expenses. A family with several siblings can easily reach a monthly consumption of 1 000 kwh.

Is 5kw 5000 watts so you can use that as a benchmark if you re unclear on what your power needs will be.
