A General Solar Equation
There are various equations for calculating how many solar panels and the amount of power needed for a household. Here’s a general example:
The average energy needs of a U.S. household is a 6.62-kW solar system to match the 9,000 kWh of average energy usage by U.S. households each year. And, the typical solar panel makes 320 watts of electricity in ideal sunny conditions. Here's how many solar panels that equals.3
Divide 6.62 kW (the system size) by .320 kW (the wattage per panel) = 20.69—rounded up that’s 21 panels. While your home is far from average, this is how you can calculate your own rough estimate
Solar Power Variables
Many factors go into calculating the best solar system size. Some of these variables include your home’s energy usage, your roof's available square footage, the solar panel wattage, and amount of sun the solar panels will receive.
For example, in Maine where sunlight is often at a minimum, homeowners prefer higher-rated panels that generate more electricity in comparison to panels typically selected for homes in sunny California. For all residences, high efficiency panels generate more wattage which means fewer panels on your roof.

Portable Desalination System from MIT in Development
https://www.yahoo.com/news/mit-engineers-created-portable-device-212012910.html
the MIT team’s device relies on a process called ion concentration polarization (ICP), which utilizes an electric field sent through membranes above and below a channel of water. The field repels charged particles and contaminants into a separate channel of water that is discarded. This allows clean, drinkable water to be produced. “We apply an electric field in the water flow and the electricity helps remove the particles like salt in the water,” Yoon explained. “That’s the basic principle of the device’s desalination process.”
