First, take the time to calculate how much you currently spend on power.
For example: A family of 3 has an average monthly power bill of $200.
At $200/month they are sending $2400 each year to the power company.
Over 30 years that is $72,000 on power
(not even counting rate increases over the years).
If this family chose to install solar panels, they are essentially pre-paying for that power.They are increasing the value of their home.
They have the peace of mind that the energy
is produced in a clean manner, at rates that will NEVER go up!
It is also possible to install the system in stages, and upgrade the entire home's usage to solar over time. Installation of a solar water heater drastically cuts the amount of energy needed to run the home, as well.
