A Residential solar power system consists of four components : photovoltaic panels, charging controller, battery pack and an inverter. The photovoltaic panels convert sun light into electrical energy. The electricity is sent in direction of the charging controller who keeps the battery pack fully charged, but not more than charged. The battery pack sends the electrical power towards the inverter who converts the DC voltage to household AC at 120 volts and 60 hertz.

Photovoltaic panel

The output of your photo voltaic panel is stated in watts. The wattage is stated is usually for peak solar various hrs. Considering that the amount of solar light varies through the course of your day, to level out the variations the peak sun a number of a long time has been adopted by most manufactures to assist installers and customer’s compare various photo voltaic panel models.

Suppose a photo voltaic panel is rated for 100 watts and an average of six peak sun various several hours is obtainable per day. Then the photograph voltaic panel would produce 100 watts * 6 peak various hours = 600 watt various several hours of electrical power or 0.6 kilo watt various a long time (KWh)

Charging controller

Charging controller or charge regulator controls the charging from the battery pack. It continually monitors the battery pack’s charge state. If the batteries are low, it will send electricity from your solar panels towards the batteries. It also prevents more than charging through the

battery pack.

Do not permit someone to convince you that a charging controller isn’t actually needed. Directly connecting the photovoltaic panels towards the battery pack can permanently damage the electric batteries and possibly trigger them to explode.

Battery pack

The battery pack’s purpose is always to store electrical electrical power generated by the photo voltaic panels all through the day after which at night or all through very cloudy days provide electric energy in direction of the inverter.

The battery pack normally consists of lead acid electrical batteries. Lead acid batteries are comparatively inexpensive and readily obtainable. There are lots of distinct kinds, sizes and capacities of batteries obtainable. Essentially the most well-known are gel cell and AGM deep cycle electrical batteries merely due to the fact they are maintenance free and last an incredible deal longer than wet cell lead acid electrical batteries.

Probably the most essential issue to bear in mind about the batteries is that the require to become deep cycle. Deep cycle batteries are created to turn into discharged then recharged hundreds if not thousands of times. A deep cycle battery is made to discharged to practically empty, but not totally and then be slowly recharged far more than time. A frequent mistake for residence owners is usually to believe that they can use automotive electric batteries instead of deep cycle batteries. Car batteries are shallow cycle electric batteries. They’re made to discharge an incredible deal of current rapidly soon after which be instantly recharged.

Inverter

An inverter converts the DC electric electrical power stored in the battery pack into household 120V AC. Almost everything in your residence is powered by 120V electrical energy. Things like table lamps, freezer, lights, motors, dishwasher, and so on.

Now you have a fundamental understanding of photograph voltaic electrical power how it functions to electrical power your house. Now you have sufficient details about how photo voltaic vitality functions to determine if it’s a technology that you would wish to invest in for your house.
