1.Solar powered home system:
A complete solar home powered system includes different componets,it will take into consideration your requirments,climate and expectations when you choose the components.They are include:
*Solar panel/solar module/solar pv panel:Which convert the sunlight instantly into
DC electric power.
*Solar charge controller:Its function is to prevent the battery
overcharging/overdischarging and prolongs the life of the
solar home system.
*Battery:Which used for storing the energy when there is an excess coming in and
distribute it back out when there is a demand.Solar panels continues to re-
charge batteries each day to maintain battery charge.
*Inverter:It converts DC power into standard AC power for the appliances use.
2. How much solar electricity do I need?
Accurately sizing the components of the solar powered home system helps ensure that your system will produce the amount of power you want it to produce at a reasonable rate of return on your investment. Consider what portion of your current electricity needs you would like your PV system to meet. A solar powered home system should be sized to meet no more than your whole load on the sunniest day of the year, and rely on some grid power or battery backup during winter or on cloudy days. If you reduce your electricity loads, you can generally buy a smaller, less expensive PV system.
In addition to how much electricity you'd like to generate, the size of your system also depends on these factors:
The site's solar resource or available sunlight;
The system's orientation and tilt;
The system's efficiency at converting sunlight to electricity;
Other electricity sources, like a utility, a wind turbine, or a fossil fuel generator.
solar powered home systems are classified by their rated power output (the peak power they produce when exposed to solar radiation of 1000 watts per square meter at a module temperature of 25°C). Systems rated between 1 and 5 kilowatts are generally sufficient
