solar power charger for ipod
Finding a way to decipher the various types of solar energy systems in this day thousands of items online can be daunting and confusing to say the less. Much of the public believes it has to have batteries for solar energy have, this is not true that as a matter of fact most solar systems residential installed today are "connected network" or "networked" with no batteries. No batteries required!
Photovoltaic systems can be configured in a variety of ways. This article describes the 7 types of settings and examples of their uses.
1. System battery with integrated photovoltaics – This system charges the batteries of a complete component system. Like the backpacks that have a cell phone charger iPod, or laptop, as well as photovoltaic panels integrated into it. Or something as simple as a solar calculator.
2. Day-use system – These systems incorporate solar panels with direct cable connection to a DC (direct current) device to any storage device. When the sun shines on the panels that have the power to the appliance. Examples of water pumping could be remote or operating fans or blowers circulation pumps for solar thermal systems.
3. QC system with storage batteries – The components of such a system consists of photovoltaic panels (or a "matrix"), a charge controller, and storage batteries. The sun shines in the matrix and charges batteries used to power DC loads (motors, appliances and equipment are DC powered. For example, a small off-grid cabin or some major road construction and signs you can see on the road.
These next 4 systems described require the use of an investor to "invert" the DC (direct current) from the PV or batteries AC (alternating current) to power AC devices and connect to the network if desired. These are the most common types of residential and small commercial / industrial / systems institutional arrangements that are in common use now.
4. System DC power, both AC and DC loads – This system has essentially the same components as the "system DC with battery storage "above except the inverter for AC appliances. These systems are used in many applications off the grill because of the availability of the aircraft AC joint and usually much cheaper than the same DC power unit.
5. Hybrid systems – solar hybrid systems are a way of using other sources covered by the battery bank as a wind generator, micro hydro, or gas / diesel generator. By relying on other sources to load the battery bank can be sure that during bad weather for a significant amount of time does not discharge the batteries beyond its desired capacity. Systems hybrids can be "networked" or "off line".
6. Connected to the network without the battery – This is the simplest system and most widely used at this time. The components include solar panels, an inverter, and a two-way meter utility. With this system you are using the grid storage device. when the network is down or down so is electricity. All investors made for network connection must "sense" of electricity from the utility network or will not work. How does a system like this works is the sun shines in the womb during the day (usually low use of loading) and powers the appliances you use and the rest goes to the power grid in the form of a credit to you, the supplier of energy, use of load at night (usually above) uses those credits to power your home. Simple right!
7. Networked with batteries – Solar systems like these are almost identical a "DC power systems AC and DC loads and / or" Hybrid Systems "above, with the exception of being linked to the network. When the network is down or down the batteries after taking the job that the network was doing. It is also called "grid tied with battery back-up. It is the second most common type of system in use today. Many commercial and institutional applications use this type of UPS, where is essential.
Some of these systems are flexible to meet the needs of individual projects. Keep in mind that all these systems, especially when it comes to batteries, are complex and require significant mathematical calculations to work properly and efficiently. They also need a facility appropriate to comply with the national state, and local electrical codes (eg, disconnects, proper marking of all components of the system and tension, etc) The national code is the NEC (National Electrical Code) # 690, this covers photovoltaics.
These are the 7 main types of solar systems photovoltaics today. This probably will change as technology changes.
I hope this helps you in your decision to go solar system and what works best for your application and budget.
