How to cull the right solar panel size
The very first footstep in the procedure of determining the size of solar panel you demand is outset determining your monthly free energy consumption. This can be done by checking your kWh reading on the nib just the best way is to add the readings from the past twelve months so split by twelve to have the boilerplate monthly consumption.
Just for comparison, an boilerplate home in the US consumes approximately 900kWh per calendar month which is 30kWh a solar day or more specifically 1.25kWh per hour. Side by side, you demand to find out about the intensity of sunlight your area receives which is chosen the sun peak hours to enable you to make up one's mind the corporeality of electricity in kilowatt-hour that 1kWh of solar console will be able to produce
With this in listen, you can at present make up one's mind the total solar system size y'all need to cover the free energy consumption that you desire to cover with solar energy.
Finally, calculate the number of solar panels you need, divide the figure of the solar system size in kilowatts to the wattage of the solar panels sold in your area and you now have the total number of solar panels needed to cover the energy consumption for your home or business.
