Energy Generation
Decentralized Energy Generation
To generate electricity from many small energy sources.
Currently, industrial countries generate most of
their electricity in large centralized facilities; such
as fossil fuels, coal, oil, and gas
Grid Tie
Small-scale power generation technologies
(typically in the range of 3 kW to 10,000 kW)
used to provide an alternative to, or an
enhancement of, the traditional electric
power system. The usual problem with
distributed generators are their high costs.
Benefits of Grid Tie Renewable
Energy Generation
Reduction in the amount of energy lost in transmitting
electricity because the electricity is generated very near
where it is used, perhaps even in the same building. This
also reduces the size and number of power lines that must
be constructed.
Typical distributed power sources in a grid tie
scheme have low maintenance, low pollution and
high efficiencies. In the past, these traits required
dedicated operating engineers and large complex
plants to reduce pollution.
One popular source of
Decentralized Grid Tie Energy
Generation is Solar Panels

How Small Scale Grid Tie
Solar Works
Solar Insolation:
A measure of energy received on a given surface area in a given
time. It is commonly expressed as average irradiance in watts per
square meter (W/m2) or kilowatt per square meter.
The sun puts out 1200 watts per square meter.
Each area in the world will receive different amounts of solar
insolation.

Facts on Solar Panels
• Currently solar panels can generate up to 18%
of solar insolation from sun. In one square
meter we can produce over 215 watts.
• Solar panels have no moving parts and require
zero maintenance.
• Solar panels commonly come with 25-30 year
warranties
• Solar Panels create DC power and can be
wired into many voltage configurations.
