Off Grid Solar Power - How it's all ConnectedTo install a grid system, contact a solar panel installation professional, as most benefits require professional installation. Make sure to look into solar power incentives available in your area and take note of any particular solar panel brands or other equipment you need to use in order to qualify for tax credits. Once your solar panels are set up, contact your power company to install any extra power meters that might be necessary. Method One of Two: Connecting to the Grid. Call a professional. Grid tied systems are probably your best bet, especially if you live in an area with reliable power.
To run completely off of solar power requires the use of battery backs that are daisy-chained together so that they work together.
If, however, you wish to continue to use mainline electrical while taking a lot of financial burden off of your back then you can do so. This is achieved by wiring the solar panels to the existing electrical supply of the home. Solar panels create DC power but the home uses AC power so it has to be converted via an electrical inverter and then that is wired to the home.
The following article will show you how to connect the solar panels to the home's existing electrical supply. This can be an overwhelming endeavor, and it may be best to get the help of a certified electrician. You will also need a permit and the electric company to inspect the work. Prior to working with the electrical box in the home you should make sure that it is turned off at the main breaker. Make use of the current tester and voltage meter to make sure that there is no active current coming from any of the wires.
You will also want to make use of the grounding wrist strap when you are working inside the electrical box even though the power is turned off. Working with DC current is slightly different than AC current as far as the wiring is concerned. The wires from the solar panels will be presented with DC power in mind as will the end of the inverter where the wires have to be connected.
If using 6V batteries, connect two in series positive terminal of one connects to negative of the otherthen connect pairs in parallel positive of one pair with positive of the other pair, negative with negative.
If your budget allows, you may consider AGM batteries, which can take more "abuse", but also cost x what lead acid batteries cost. Make sure the Ah ratings of all batteries added together is higher than the capacity you calculated in the previous step. If using multiple batteries, make sure to get multiples of the same battery, and to get them all new or reconditioned at the same time.
Mixing different capacity, model, or age batteries can shorten all of their lifespans.
How to Hook Up Solar Panels to an Electrical Supply
Buy a charge controller. The most important thing is to actually use a charge controller. If you hook up solar panels directly to some batteries, the batteries will charge for a while, but they could quickly be ruined. Whichever charge controller you get needs to support the amount of current your solar panels produce. Most charge controllers are rated in Amps, so divide the Watt rating of your solar panels by 12V e.
Find a charge controller with a rating higher than your theoretical estimate. This will give you a safety margin, as well as some headroom for growth in the future.
Beyond that, exactly which charge controller to buy is basically a trade-off between cost vs efficiency and battery-life.
The more expensive charge controllers will use different charging algorithms best suited to the type of battery you have. They also may compensate for temperature to better protect your batteries. If you plan on running devices off of AC power i. There are broadly two types of inverters: modified sine wave and pure sine wave. However, if you've followed all previous steps as recommended, your set-up should have the excess capacity to absorb this inefficiency.

Then hook your light up to the battery. Not Helpful 12 Helpful Can I have a solar panel with an inverter and no battery to run just during the day?

At the equinoxes, the sun is 90 degrees minus your latitude N. At he start of summer that angle will be about 23 degrees greater and at the start of winter about 23 degrees less. For example, at latitude 38 deg N, the elevation angle would be 52 deg Sep 21 and March 21, 75 deg on June 21 and 29 deg on Dec If you're doing this manually, you're likely not going to be changing this only once or twice a month.

The key to small solar setups is to reduce consumption. Warnings Lead-acid batteries contain lead, and acid. They can also emit hydrogen, which is explosive. With small solar setups, it is easy to use up too much power, which can result in temporary power outages. If you have a severe electricity addiction, you may need to consider a larger more expensive and complex setup with more capacity and redundancy.
If you screw up badly enough, you can break devices. Sometimes even expensive devices. But then you learn from it, and generally won't make the same mistake again. Electrical current can generate heat, and excess heat can cause fires. Electricity can kill you, though touching both terminals of a 12V battery usually won't be much worse than a static discharge, so don't be too scared in fact, static discharges can have much, much higher voltages than 12V.
