Product DescriptionSolar Home System
Indonesia is one country that carry out the Bali Road Map in 2007 and the Copenhagen Protocol in 2009, which has a c ommitment to reduce carbon gas emissions each year. Utilization of renewable energy sources like Solar Power Plant (PLTS) in replacing the Diesel Power Plant to reduce emissions of carbon gases. Solar Power Generation or so-called Solar Home System is generally in the form of small-scale systems, using solar module 50-100 Wp (Watt Peak) and generate electricity daily of 150-300 Wh. The use of SHS is also in line with the program of PT PLN (Persero) is determined to complete the waiting list electric customers throughout Indonesia
SHS installed in decentralization (one house a plant, so it does not require a distribution network) SHS ideal for remote areas or areas that are not included PT PLN distribution network. Currently the use of SHS is not merely just for lighting but can also be used for television systems. In Indonesia, demand for this system started to show increased since the 2000s along with a vigorous campaign for urban green energy and the removal of fuel subsidies by the government in 2005, which makes the cost of generator operation, especially in the area (island) remote becomes increasingly expensive and lead to price PLTS increasingly competitive.

Installation of SHS system begins with the installation of solar modules in a place that is not prevented from receiving sunlight, usually mounted on rooftops, or in front of the house using a pole with a height of approximately 5 meters. The module is connected to a battery located in the battery box. At Battery Boxes Battery Control components are also used as a controller unit to the electrical equipment to be supplied power by the SHS. After installing the module then made the installation of cable homes that are tailored to the location of the lights in the house. Components of SHS can be seen in the figure below.

Social benefits to adopting the proposed technology are:
1. Reducing the burden of women to collect firewood and facilitates alternative additional activities to fill the time available, especially for female
2. Provide lighting (lamps) with better quality, so the hour long learning and more activities.
3. Improving access to information (radio, TV).4. Creating new business opportunities in the village by becoming a
distributor, and service centers that can be done by cooperatives.
5. Creating employment in the village, as the sales center, and service centers that require local power.
Technical Feasibility
The capacity of a SHS used can vary depending on user needs, ranging from 50 WP, 80 WP to 100 WP.
SHS installed system has a power output and the use of lighting in different amounts. In addition to the total use of lights and power output, system SHS has the kind of output voltage AC and DC.

Component SHS
1. Solar Panels, changing intensity of sunlight into electrical energy. Solar panel / solar cell produces a stream that is used to fill baterai.
2. Controler, which is its function as a regulator of both the flow of electrical current that flows in and out / be used.
3. Battery, its function is to save electricity.
4. Inverter, its function if the electrical equipment / electrical loads using alternating - (AC), the PLTS system because its function is required to use an inverter that converts direct current into alternating power - behind. In operation, the inverter also requires electrical power consumption to run
