Did you know that there are 10 various parts that are required to make a complete solar powered system for your home? However, it doesn’t necessarily follow that you will have all the items built into your system. You can start off simple and add to it as your requirements change.
Don’t feel to intimidate by the options or complexity of the different systems it is really very simple. Remember you can start with a simple system and then add to it over time, as and when your experience and knowledge increases.
Solar Cells
The PV solar panels are positioned so they get maximum sunlight throughout the day, and they turn sunlight into solar electric power. Unfortunately, they produce DC power, so we have to change this to AC power. Go crazy and build loads of solar panels because you can connect an unlimited amount together. 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. The more panels you have, the more energy you produce.
DC (Direct Current) Disconnect
You want you solar panels connected to a Direct Current (DC) disconnect. This is a vital piece of kit as it switches off the electricity generated by your solar panels. This now allows to carryout maintenance on any other part of your system.
Charge Controller
If you have a battery backup or a battery bank then a charge controller is a must have piece of equipment. If you have a charge controller, this will protect your batteries from becoming over charged. Over charging will reduce the life of 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.
To get the best out of your batteries and to extend their working life, keep them at an ambient temperature. If you don’t have room in the house for them, make them a shelter outside, never leave them exposed. A battery box is also a good investment, they keep your batteries at a good temperature and also protect them from accidental damage.
System Metering
Your solar system meter is, in effect, your dashboard. It tells you the amount of electricity you are generating, consuming and how much is stored in your batteries. Without a system meter, you are working blind.
Main Supply DC Disconnect
If you have a battery bank then you will need a main Direct Current disconnect. You want to locate it between your battery and your alternating current and direct current inverter. Again it is very handy if you want to do any systems maintenance.
AC DC Inverter
Batteries and solar panels output a direct current. What we have to do is convert this DC current into an AC current. We convert DC to AC using the inverter and so all your electrical home appliances work without any problems.
Petrol Generator
You can get petrol and diesel powered generators. You will want one of these if you are not connected to the national grid. The generator can produce electricity when there is no sun or when the batteries are run down.
AC Breaker Panel
The AC breaker panel switches off the flow of electricity either from the grid to your home or your home to the grid. Every house has one of these; however, you are not allowed to touch it. You have to get the electric company to come along and wire it up for you.
It makes sense really, if you get this bit wrong it can be very costly, and you don’t want to end up with the blame for anything.
Home Kilowatt per Hour Meter
All homes which are on-grid are fitted with a kilo watt hour meter. This what the electricity company uses to record how much electricity you have used.
