How A Solar System Works
If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!
I´ll show you briefly How Solar Power Works so you understand how the panels are connected to batteries, inverters and other important gear.
Solar cells, also called photovoltaic (PV) cells, permit you to work with the sun’s energy to create energy without noise, pollution, breakable creations or fossil fuels. That permits you to considerably reduce your carbon footprint and protect yourselves from annual utility rate rises.
BATTERIES
Solar PV installations come in two ways: including battery and direct. In the case of battery installations the sun charges the battery on bright days (it´s not the direct temperature of the sun that makes a PV system effective, it´s the power of the solar radiation. Standard battery installations for rural houses and off-grid installations produce slightly less electricity (18 kilowatt hours) than the normal family electricity usage (20 to 30 kilowatt hours). Battery installations are though not only fitting for off-grid solar power systems, they as well work as storage in regular grid connected homes for when the sun doesn´t shine.
To understand How a Solar Panel Works, you should be aware that it is not possible to merely plug your solar system into your house wiring as the voltage output generated by your solar installation change wildly due to instable solar intensity all through the day. This would blow away your home equipment since it´s very vulnerable to energy changes. You require specific equipment like batteries, inverters and transfer switches. Batteries act both as storage and as a buffer to absorb the changing power output of the panels and shield the inverter.
In an city region you are connected to the electricity grid (direct system) and a battery is not considered necessary (though can be useful in situations of power lacks for example). You can make use of the electricity produced by the sun to power your dishwasher through the grid connection.
A battery is used to store the energy that the solar panel produces when the sun is shining and to make that energy available to your electrical devices at your house when it´s necessary (that is at nighttime and when the sun doesn´t shine). When you are not able to supply the generated power to the grid (which is the case for diy solar systems due to the technical requirements of your utility company), you ought to have a battery-bank. That is exactly the way how solar works.
Even though a PV panel produces energy when the sun is shining, there are other items besides the batteries, needed to conduct, control, convert and distribute the generated electricity.
Which of these items you would require, depends on what way you would use your Home Solar Energy System. You would though without doubt need an inverter that converts your collected Direct Current (DC) energy from your batteries to alternating current (AC) that your electrical devises at your house use.
INVERTERS
A bank of batteries can usually give you 12volts, 24volts, or 36volts, whilst grid electricity is generally at 240volts. The inverter multiplies the 24volts into 240volts required for the home electric devices. A ‘true sine wave’ inverter delivers a harmonious stream of energy to your devices, just similar to the stream which comes from the grid. Matching the stream as it comes from the grid protects your sensitive appliances like your PC´s, a fridge or appliances that include a dimmer, or a speed control. This you want to know to realize How a Solar Panel Works.
Now you understand How Solar Energy Works, are you ready to decide to decrease your power bill and that you won´t have to pay the constantly increasing energy rates, than you could run to the local solar contractor or make the installation by yourself.
