The next big thing in solar energy could be microscopic.

Scientists at MIT and Harvard University have devised a way to store solar energy in molecules that can then be tapped to heat homes, water or used for cooking.

The best part: The molecules can store the heat forever and be endlessly re-used while emitting absolutely no greenhouse gases.  Scientists remain a way’s off in building this perpetual heat machine but they have succeeded in the laboratory at demonstrating the viability of the phenomenon called photoswitching…”

“Learn the basics of solar panels, inverters, installers, siting, financing and more. Harvest your own clean energy from the Sun.

The following guide will help you start exploring the possibility of going solar at your house. Let’s first get up to speed on solar electricity basics with a few key definitions:

PV Module: aka a solar panel, converts energy from the sun into direct current (DC) energy. PV Modules come in varying wattages and sizes. Typical PV modules used on home installations are 200 watts and about 14 square feet.

PV Array: A number of PV modules wired together. Using 5 x 200 watt PV modules creates a 1,000 watt PV array. Typical array sizes range from 2,000 to 5,000 watts and up.

Inverter: Converts DC electricity into alternating current (AC) electricity used around the house. A 3,000 watt inverter will output 3,000 watts of AC electricity given enough PV input. Typical inverter sizes range from 2,000 watts to 7,000 watts…”
