Decentralized, Grid Tie Energy Generation

Decentralized Energy GenerationTo 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.

Cost Comparisons of Energy Generation

Installed Solar Systems: 90-120 USD/KW(2700-3600 Baht per KW)

Coal Power Plant: 56-95 USD/KW(1680-2850 Baht/KW)

Nuclear Power: 200-600 USD/KW(6000-18000 Baht/KW)

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.
