How Does The Differnet Items Of A PV Solar Powered Electrical System Work Together?
There are ten different components that make up a solar powered generating system. Depending on what type of system you want to implement will depend on whether you use some or all of them.
Don't feel to intimidate by the options or complexity of the different systems it is really very simple. For example, we talk about having a diesel generator as a back-up system, but you don't to have to start off with one, and you can add it at a later date if you think it is necessary.
PV Solar Panels
These solar panels face the sun and convert the suns energy into power. They produce DC electric power in contrast to AC. You can connect as many panels as you like together, this is called a solar panel array. Follow this link find out more about how to build a solar panel.
They are connected in series so the flow of electricity is from to the next one in line. With this design, it is very easy to add more panels as and when you build them.
DC (Direct Current) Disconnect
You want you solar panels connected to a Direct Current (DC) disconnect. You do not want to undertake any maintenance on your system while there is electricity flowing through it. The DC disconnect switches of the power generated by your solar panels.
Charge Controller
A charge controller is very important to have if you are using batteries to store electricity. If a battery gets over charged it can become damaged. A charge controller is designed to protect your batteries.
Batteries
Learn about the various types of batteries that are available. The type you need is deep cycle. These batteries are often used in forklift vehicles. Do not use car batteries.
Keep the batteries warm, that way they work better. If you don't have room in the house for them, make them a shelter outside, never leave them exposed. The other thing you might want to think about is getting a battery box. They are great for protection and keeping batteries warm.
System Metering
A system meter is very useful for telling you how much electricity you are using and how much power is left in your batteries. Without a system meter, you are working blind.
Main Supply DC Disconnect
The main DC disconnect is used to turn off the power from your battery. It is placed in-between your battery bank and your inverter. This turns off the power from your batteries, which then allows you to undertake any preventative maintenance.
AC DC Inverter
Solar panels and batteries produce a DC current. The problem is, many if not all your electrical gadgets in the home use an alternating current. We convert DC to AC using the inverter and so all your electrical home appliances work without any problems.
Petrol Generator
Check out the many types of fossil fueled generators. If you live in a house that does not have an electric utility supplier then this is a good option to add to your system. The generator can produce electricity when there is no sun or when the batteries are run down.
AC Breaker Panel
The AC breaker panel is where you feed the electricity you produced back to the national grid. Only your electricity supplier is allowed to touch these panels. So you need to book an appointment for your utility supplier to wire it up to your solar panels.
Don't be tempted to do it yourself, it is a criminal offence for unqualified people to touch these panels, and you want it to be done correctly..
KW per Hour Meter
As with the breaker panel, you will also have a KWH meter. This what the electricity company uses to record how much electricity you have used.

Once you know how to build a solar panel you now need to source all the other components to build a complete system to power your home. Visit build a solar panel and learn all you need to know about building the right system for your house.
