How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?
Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
The panels are relatively easy to install. The batteries and the inverter tend to be heavy and you will need many people or mechanical assistance. You are talking about high current DC thus if you touch the wrong wires it's CC (Cancel Christmas - Rescue Squad Term). You also also dealing with lead acid batteries so they need to be well ventilated or we have another CC situation. Should you have a short, the batteries will overheat and explode projecting sulfuric acid... And the best part is when all is said and done, you are only paying twice to three times the cost for the electric over the life of the system as compared to buying the electric from the power company.
