What factors affect the cost of solar panels for your home?
There are many factors that affect solar panel installation cost with respect to a specific home including:
The location of your home
The location of a home affects the cost of installing solar on it in a few ways. The average cost per watt of solar systems varies around the country leading to different solar system costs, and also the amount of sunlight in each location affects the system output, so you would need a different number of solar modules which directly affects the total system costs.
The amount of electricity your home uses
At the risk of stating the obvious a house that uses more electricity will need more solar panels. Although solar panels get cheaper on a per watt basis as the system size gets bigger, the overall cost of the system increases for homes that use more power.
The type of solar panels and inverter you buy
There is a significant difference in cost between the best solar panels and other less well-regarded brands. The same is also true for inverters. For example, a 6kW solar system using Sunpower or Panasonic solar panels can be $5,000 more expensive than a solar system using Canadian Solar Modules. They shouldn't be, but often they are.
The relative ease or difficulty of installing solar panels on your home
If your home is three stories high or has a roof with a 45° pitch then it will take longer to install the panels and do the wiring. This will translate to more installation labor and higher cost.
Calculate how much power solar panels will produce on your home
How to calculate how much solar panels will cost for your house with our solar panel cost calculator?
Our solar power calculator allows you to work out the likely solar panel installation cost for your home requiring only the input of your address and monthly power spend. From this it knows your utility company, your utility's electric rates and how much power you use.
The solar panel calculator will assume you want to install a solar power system that will produce the same amount of electricity that your home uses and will calculate how many solar panels you will need to power your house. This is because net metering laws limit the size of eligible solar systems to a system producing a similar amount of energy as your house uses.

How to calculate solar panel cost for your home without collecting power bills?
While there is data on average electricity use of homes in each state and how many solar panels are needed to power an average house in each state these averages are of little use as most people considering solar tend to have electricity usage almost double their state average.
The short answer is YES but don't worry our solar panels calculator provides an easy estimate of the number of solar panels needed to power your home. All you need to know is your energy bill for the last month and your utility company.
The solar power calculator produces a ballpark estimate just from an average monthly power spend.
Does how much power solar panels produce in your city affect the cost of solar for your home much?
The National Renewable Energy Laboratories (or NREL) have produced sophisticated and accurate data that shows, how much electricity do solar panels produce (in kWh) for each of the more than 3300 weather locations around America.

Will solar save you enough to get a short payback period on the upfront cost of a solar panel system for your home?
The solar savings estimator will also calculate how much solar will save you. The size of your solar savings depends largely on how expensive utility electricity is in your region, what the future rate of utility price inflation proves to be and of course how much power you use.
Solar payback periods can now be as short as 5-6 years leaving homeowners installing solar now to enjoy 20 years or more of free electricity after this period. The solar calculator will work out your solar payback period.
