More and more people wonder if they can use solar energy to power their house.
If you switch to solar power on your house you will find yourself dramatically decreasing your energy bill. To start using solar energy to power your house, all you have to do is make a solar generator at home.
Solar generators can be built at home for between 0 and 0. A 12-volt solar panel takes about five ours of constant sunlight to charge and runs for about five hours powering a 115-volt AC. If you want more power, you can easily wire more solar panels together and connect them to the generator.
How to use solar engery to to power Your House
This particular solar generator has the capacity to power a fan, small TV or a laptop, and can also run small appliances. The sunlight will be caught by the solar panels and converted into solar power that can produce 400-watt hours of energy. In order to boost the power of the generator, more solar panels can be purchased and wired together to increase the energy gained from the sun.
How to Build a Solar system
Step 1: Decide what you want to put the solar power generator in and purchase it. You can use a battery box, a plastic cooler, or a wooden crate. A plastic cooler works well if you want to place the generator outdoors, as it will be durable against the weather elements.
Step 2: Use your drill to make a hole at the top of the box. You’ll probably want to place the hole off to the side somewhere. Then stick the voltage meter through this hole. Use the insulated wire to connect the voltage meter on one side and the wing nut terminals of the battery on the other side. It is important to always keep in mind that the negative pole should be connected first, and only touch one wire at a time.
Step 3: Check the manufacturer design to ensure that the solar panel has been properly wired. Then connect the solar panel and the DC inlet to your battery terminals, once again ensuring that the negative poles are connected first. Once all wires have been properly connected, close the lid of your solar panel generator box and place it in a bright, sunny location so that it can charge completely.
The Materials to build a system
12-volt solar panel SunGuard 4-am charge controller 32 am-hour sealed battery. DC input 175-watt DC to Ac power inverter Voltage meter Insulated wire Drill
First of all you want to make all of your purchases. The 12-volt solar panel can be purchased from an RV or marine supplies store and cost between 0 and 5. Do a search on google for your SunGuard 4-am charge controller. These will cost about , but be sure you research your online retailer and only purchase products from reputable retailers.
A 32 amp-hour battery will cost approximately and can be found at a marine store or online. A DC input can be found at a car parts store. The 175-watt DC to AC power inverter will cost about and can also be found at a car parts store. Don’t forget to find a voltage meter, some insulated wire and a drill.

Then How to test solar controller?
im constructing a solar charge controller and i have a functioning dc-to-dc converter, current and voltage sensors, but i dont know how to go about testing it. Ive only tested the power supply using a desktop DC power source and an electronic load. I need help and advice on how to start testing the controller -- what to look out for, how to connect everything etc. Im new to this and I have a deadline coming, i need help. thanks very much!
You need a meter known as an "amp meter to test solar panels. An amp meter has to be connected to the negative and positive part of the solar power panel and then the panel is activated to carry out the test. The meter measures using a measurement termed the "short circuit current", which is the quantity of current that the panels can generate. Amp meter that is used for the testing should be more powerful then the panels, otherwise an accident can occur.
12V Solar Panel — Where Does it Come From?
What is a 12v solar panel and why 12v is such a magic number? First of all let’s talk about kind of electricity generated by solar panels, because it’s different from what runs in power outlet in a typical household. Solar panels generate so called direct current electricity, while regular 110V power outlets give you alternating current. Because it’s a different kind, you can not really compare 12V to 110V. So, where solar panel with 12V comes from?
There are two different kinds of electrical solar systems. Completely stand alone and independent setup is called off-grid system, while solar panels hooked up to regular utility grid is called on-grid. For both cases the same kind of solar panels is used and usually it is 12v solar panels, because standard battery is 12V. For example battery in your car outputs 12V direct current electricity too. This is why if you get a solar panel 12v would be the most common voltage.
12v solar panel
It does not mean that you can’t have different voltage (especially if you make your panels yourself). You also can combine several panels to get higher output voltage if needed, so you could get 24 volts out of two 12v solar panels, 36 volts out of three 12v solar panels and so on. Some batteries for off-grid systems are 24 or 48 volts, in this case you will have to combine several panels in order to be able to charge your batteries.
The last thing to consider (this mostly applies to RV solar panels though), what kind of appliances you will be running from your solar electricity. There are plenty of standard 12V dc appliances available, so it will really save you a lot of headache if you equip your solar system with standard 12V batteries and 12v solar panel, in this case you don’t have to convert electricity.
