Off grid solar power system calculator.
Solar panel size calculator uk.
One solar panel produces about 1 24 kwh per day.
For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142.
Simply enter the average power you use per hour and number of hours used per day.
Installing solar panels can be a great decision for your home for the environment and for your savings.
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.
In fact with an average return of 4 8 over 25 years solar panels offer a return comparable to most isa and investment accounts.
To calculate the number of panels you need divide the hourly energy usage of your home by the wattage of the solar panels.
A 5kw solar system may produce enough energy to power your home but you may not have enough roof space for a system of that size.
A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.
Pv solar panels tend to vary between 150w to 345w per panel depending on the size of it and the cell technology use to create each of the modules.
The number of panels the roof layout the overall system size allowing space for roof mounting equipment and example power output figures kwhrs are provided for each system.
Our calculator will give you 2 options.
Use this calculator to quickly estimate how many large solar panels you could fit onto a roof and roughly calculate how much power they could generate kwhrs.
