Based upon the book Solar Power For Your Home, The Green Living Guy has created Solar Power 4 Your Home. We will help you get solar installed and we definetly need to add energy storage / backup. Let’s make you energy independent!
What is solar energy and why go with solar power?
Let’s face it, the sun has been producing energy for billions of years. Here is the history of its
use by humanity.
(A) Solar Energy and Power
Solar energy is the light and heat from the Sun that has been harnessed by humans since ancient
times using a range of ever-evolving technologies. Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes:
- space heating and cooling through solar architecture
- potable water via distillation and disinfection
- hot water
- thermal energy for cooking
- high temperature process heat for industrial purposes
(A) Solar Radiation
Solar radiation (along with secondary solar resources, such as, wind and wave power, hydroelectricity and biomass) account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.
A) Solar Technologies
Solar technologies are broadly characterized as either passive solar or active solar depending on
the way they capture, convert and distribute sunlight. Active solar techniques include the use of
photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert
sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun,
selecting materials with favorable thermal mass or light dispersing properties, and designing
spaces that naturally circulate air.

The sun’s heat and light provide an abundant source of energy that can be harnessed in many
ways. There are a variety of technologies that have been developed to take advantage of solar
energy. These include concentrating solar power systems, passive solar heating and daylighting,
photovoltaic systems, solar hot water, and solar process heat and space heating and cooling.
Solar power can be used in both large-scale applications and in smaller systems for the home.
Businesses and industry can diversify their energy sources, improve efficiency, and save money
by choosing solar technologies for heating and cooling, industrial processes, electricity, and
water heating. Homeowners can also use solar technologies for heating and cooling and water
heating, and may even be able to produce enough electricity to operate “off-grid” or to sell the
extra electricity to the utilities, depending on local programs.
