Components of a Home Photo Voltaic Energy Program.

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

Photovoltaic panel

The output from the picture voltaic panel is stated in watts. The wattage is stated is commonly for peak solar numerous a long time. Given that the quantity of solar light varies via the course of the day, to level out the variations the peak sun several several hours has been adopted by most manufactures to assist installers and customer’s compare numerous 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 really required. 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 to store electric power generated by the photo voltaic panels throughout the day after which at night or throughout very cloudy days offer electric electrical power in the direction of the inverter.

The battery pack typically consists of lead acid electrical batteries. Lead acid batteries are relatively inexpensive and readily obtainable. There are lots of unique kinds, sizes and capacities of batteries obtainable. One of the most well-known are gel cell and AGM deep cycle electrical batteries simply since they are maintenance free and last a great deal longer than wet cell lead acid electric batteries.

Essentially the most vital issue to bear in mind about the batteries is that the will need to be deep cycle. Deep cycle batteries are created to become discharged then recharged hundreds if not thousands of times. A deep cycle battery is intended to discharged to almost empty, but not completely and then be slowly recharged a lot more than time. A common mistake for home owners is usually to believe that they can use automotive electrical batteries instead of deep cycle batteries. Automobile batteries are shallow cycle electrical batteries. They’re developed to discharge an excellent deal of present rapidly immediately after which be instantly recharged.


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

Now you’ve a fundamental understanding of photo voltaic energy how it functions to strength your house. Now you’ve sufficient information about how photograph voltaic power functions to determine if it’s a technology that you would wish to invest in for your home.
