Using Solar Energy


Nowadays people make up to realize the environment preservation. The use of environmentally friendly energy began to be noticed. The effects of global warming and the greenhouse that we feel now is adding the awareness of this problem. One of the environmentally friendly energy alternatives that can be used is the use of solar energy. Bulk power generation now usually using coal as fuel. This heightens the carbon emissions released on the air and increase the greenhouse effect and global warming.

This writing will not discuss the technical utilization of solar energy for household use in detail. You need a professional at it if you want to install solar panels for your needs. However, this writing invites to think about the use of environmentally friendly energy. Especially this solar energy. The use of environmentally friendly energy is sensible thought. The existence of a safe and healthy environment is necessary to ensure our future descendants living space.

Availability of Solar Energy

The first thing you need to think in the utilization of solar energy is the availability of sunlight. For tropical countries such as Indonesia, it is certainly not a problem. What matters is the willingness of people to take advantage of solar energy for their household needs.

Space Availability

The second thing to think about this is the sufficient space availability for the installation of solar energy equipment. This space is needed for solar regulator, battery, an inverter to convert the DC electricity into AC current and of course the solar panel itself. Solar panels require quite spacious room. If you're building a house, the solar panels can be integrated in development. Tile directly facing the sun is the best option for installing solar panels.

Battery Needs

To calculate how much battery is needed in the installation, first of all, we need to know our daily power needs. This requirement could be seen from the MCB installed on the house. Suppose we need a power of 2400 kWh per day. Multiply by 120% for energy reserves so we get 2880 kWh. An additional 20% of this is to add power to the inverter which serves to convert the DC current into AC current. Most household appliances use AC current to work.

If we use a battery with 65Ah 12V capacity, it means we need four battery. This value is derived from a count of 2880 kWh = 65 Ah X 12V X 4battery.

Solar Panels Needed

There is a wide selection of solar panels available on the market. If we use a panel with a capacity of 100 kWp (watt peak) then the power generated by a panel, every day is about 500 kWh. This result is obtained by multiplying the value of 100kWp with an average time of solar panels exposed to enough sunlight which is about five hours.

The number of solar panels needed can be obtained by dividing the power requirement of 2880 kWh to the amount of power generated by a solar panel of 500 kWh. Retrieved number of panels required is 6 panel pieces.

Such an overview of the utilization of solar energy. The order of installation is a solar panel connected to the controller to prevent excess currents entering the battery. And from the battery current is passed through the inverter before use. Once again, inverter is required to convert the DC current produced by the solar panels into AC current used by most household appliances.
