Solar power system is one of renewable energy system that uses PV modules to convert sunlight into electricity. Solar PV system has components that should be selected according to your system type, site location and applications. The major components for solar PV system are solar charge controller, inverter, battery bank, auxiliary energy sources and loads (appliances).
• PV module – converts sunlight into DC electricity.
• Solar charge controller – regulates the voltage and current coming from the PV panels going to battery and prevents battery overcharging and prolongs the battery life.
• Inverter – converts DC output of PV panels or wind turbine into a clean AC current for AC appliances or fed back into grid line.
• Battery – stores energy for supplying to electrical appliances when there is a demand.
• Load – is electrical appliances that connected to solar PV system such as lights, radio, TV, etc.
The first step to designing your renewable energy system is identifiying your power usage. To design a system that works for you, knowing your energy usage is critical. If you want to save money on your new system, think about ways to reduce your energy use.
Locating your Kilowatt Hour (kWh) Usage for twelve consecutive months. Ask your utility for this information or look at past utility bills. Discover the average kWh Usage by adding up the kWh for each month and divide that by 12. Note which months use the most energy. Write this number down. Your average kWh per month determines what the size of your solar electric system would be.
Review various systems to get a better understanding of what type of system will fit your needs. Renewable Energy Systems come in many shapes and sizes. What’s the main reason for adding solar: saving money OR being independent of the utility?
-Grid-tie systems lower your electrical bill, but need a connection to the utility company.
-Off-grid systems allow you to live and work where utility power is either unavailable or too expensive to bring in. This option offers independence, you save money.
-Grid-tie systems with battery backup allow both of the above, but are more expensive to begin with.
Once you know your system type, your next step is to choose what size your system needs to be. If you plan on living Off-Grid, you need to know how much power your appliances draw. If you’re staying connected to the grid, you’ll want to have the average Kilowatt Hours (kWh).
