The Use Of Alternative Renewable Energy | Solar Panel

The use of alternative renewable energy such as sunlight, the more desirable. But not many people know how the application of solar panels for retail or residential consumption.

Solar panels consist of several types, including types of Monocrystal, Polycrystal, and Thin Film. Each type has the power absorption of solar radiation that is different, depending on size of panel with a unit of measure Watt Peak (Wp). Chaqoqo explained, Product Marketing & LED Light Photovoltaic Marketing Department, Sharp Electronics Indonesia. About the price of solar panels, said Chaqoqo, the average per watt peak should consumers spend about $ 4, 5 - $ 5.

"Each panel can produce a different electrical current, according to the type of solar panels," said Chaqoqo. Example, type 60 Wp panels can produce power at 60 watts per hour at peak solar heating conditions (peak), which accounted for about 4-5 hours per day, between the hours of 9 am to 2 pm.

So if the totalized per day of heating, using a panel of 60 Wp to generate power: 60 watts x 5 hours = 300 Wh (Watt Hour). For other types of panels, said Chaqoqo, such as type 130 or 185 Wp Wp, penghitunganya same way.

On and Off Grid Systems Grid System of Solar Panel

There are two types of installation of solar panels that can be applied, each related to the equipment used boosters.

First, On Grid System Installation (intalasi without Using Solar Panels Battery). The equipment used is On Grid Inverter can be in direct connection with the source of electricity or other power source.

Secondly, Off Grid System Installation (Installing Solar Panels use a battery). To intalasi Off the Grid with the DC system, the equipment in use is the solar panel, controller, and battery. To convert it into AC current, the inverter must be added. (See picture below)

For installation or installation of such equipment, can be done alone, said Chaqoqo, especially for solar panels with a small capacity (60 Wp). But for large scale and connected to many networks, specialized expertise required for the installation process.

Some people ask, after the use of solar panels, how about the installation of electricity that has been previously installed. In response, Chaqoqo say it depends on the needs. If electricity is not needed anymore, then the network can be removed (using the Stand Alone System). Conversely, if the electricity is still needed, preferably using a hybrid system.

Calculation of Solar Panel Cost

Chaqoqo provide simulations for installed electric capacity of 450 watts, which need to be considered is the electrical capacity in use.

Electricity used for example as follows:

1 unit used 24 Refrigerator 100 Watt Hours = 2400 Wh

1 unit LCD 32 "80 Watt used 5 hours = 400 Wh

7 Watt 10 LED lights are used 10 hours = 700 Wh

Total 187 Watt / Hour = 3500 Wh

Can be seen from the table above, the installed capacity of 450 watts of power installed, which is used is equal to 187 watts per hour. If you add up the total electricity consumption per day is 3500 Watt Hour.

Preview How to use a simple calculation Solar Power:

Wh 3500: 130 Wp (Solar Panel Type) = 26, 92

26.92 unit: 5 hours (Old heating per day) = 5384

5384 x 1.5 (Minimal power Autonomous) = 8 units (figure rounding)

The electricity generated is:

8 units x 130 Wp = 1040 watts per hour at peak heating heating (peak).

Within a day, or less able to produce electricity for 1040 hours Warm-Wp x 5 = 5200 Wh.

So to load installed 450 Watt power, equivalent to the capacity of 1040 Wp or 5200 Wh using 8 units of type 130 Wp panel and power storage unit (battery) 12V 100 Ah capacity of 6 units, one unit of Battery Charge Control, and an inverter unit, bracket , panel box, battery box, and other supporting equipment.

From this it can predict how much investment should be spent, said Chaqoqo. Approximate count of convenience, the system capacity multiplied by $ 10 (price estimate).

So, an example of the power calculation, the value of investments that must be spent during the initial installation amounted to 1040 Wp x $ 10 = USD10.400.

"An example of this calculation is to install off grid system," said Chaqoqo. When in-rupiahkan with Exchange Rp9.300, he added, the total investment ranges from Rp96.720.000.

"This is the estimated price, including installation costs, provision of equipment boosters, and guarantee the installation of the system between one dampai three years, depending on the system integrator managing  the installation," he explained. "Meanwhile, for the solar panel is guaranteed for 25 years."

Chaqoqo explained, the orientation of the use of renewable energy, particularly solar power is for the long term. This means that for certain areas with electrical conditions are fulfilled, then the total investment will look expensive, because consumers are burdened with the cost of installation to be issued simultaneously.

"But for certain areas with electrical conditions are not met its full potential or do not have electricity at all, then solar power will be an option, because the solar electric system requires no fuel at the time of operation, making it cheaper when compared to the cost of purchasing the purchase and transportation .
