Integrated/Hybrid power
• Hybrid power are combinations between different technologies to produce power.
• Hybrid systems combine two or more modes of electricity generation together, usually using renewable technologies such as solar photovoltaic (PV) and wind turbines
• . The gasoline/kerosine engine drives the dynamo which charges the storage battery.

1.Introduction of solar sail deployment concept
![Page 15: Integrated system future power](https://reader034.vdocument.in/reader034/viewer/2022052418/58f0f3c41a28aba86d8b45db/html5/thumbnails/15.jpg)
Important requirements• Solar sail deployment system• Thin ,flexible solar panels• Wind turbines• Temperature Sensors• Actuators
![Page 16: Integrated system future power](https://reader034.vdocument.in/reader034/viewer/2022052418/58f0f3c41a28aba86d8b45db/html5/thumbnails/16.jpg)
Thin solar panels• Researchers at MIT have created
prototype solar cells so light and so thin, that they can be balanced on the surface of a soap bubble without breaking it.

Flexible solar panels• The production of flexible solar
panels requires as little as 1% of the amount of silicon used in rigid crystalline panels. In addition, the sunlight absorber layer is cadmium free (environmentally friendly), as well as a commercially viable, low cost technology.

Thin – flexible solar cells• Solar En ergy Tech no logy has de veloped a method
to man u fac ture su per-thin, light-weight, and flex ible solar cells re quir ing 75% less energy to produce and 90% less silicon materials than sim ilar pan els. • The product is the out come of com bin ing the ad
vant ages of flex ible thin-film solar cell tech no logy and highly effi cient crys tal line sil icon tech no lo gies. • The solar cells can reach an efficiency of up to 22%,
while also per form ing well with wide-angle and weak light.
