Even an ‘all batteries low’, start the generator box.īiggest drawback was I had battery problems and had to re-wire everything to 12 VDC. I do have a few homemade automated steps in the system. I have lockouts hanging on the wall next to the load center to prevent ‘accidental’ re-connection. Like Ken, my switchover of the mains is manual. Might even put in a 220VAC GFI, just in case. Since you have two systems, I would look at dedicating one to the water pump, acquire a 220VAC inverter, and manually control the water pump. There’s a lot of places that have good deals on ‘last years’ products. Keep track of the prices, and jump on the best deal when it pops up. Your better effort, IMHO, is to search a lot. > Renogy Kit – 200 Watt, 12-Volt, 40-Amp, MPPT Controller A few panels up on the roof can make boondocking a bit more comfortable! Solar power systems are also becoming popular for RV’s. Maybe just several hundred watts to charge several deep cell 12-volt batteries connected to an inverter (for example). Some people may choose to put together (or at least have on hand) a small system for ‘just in case’. I’ve integrated it through ‘transfer switches’ for some of my home’s electrical circuit breakers. I built an off-grid solar power system which is ‘side-by-side’ with my home’s grid power. Hover, It’s Worthwhile for Many!ĭespite the cost of a given solar power system, for many it’s a worthwhile investment.Įxample: If purchasing a new property with land far from the nearest road with electric utilities, it may actually (very likely) cost less to implement a solar power system than pay to run electricity to your property.įor the preparedness minded, simply having a very basic solar power system (or bigger) provides some peace of mind (at least it did for me). Why? Because a cost analysis of a solar power system compared with that of your electric utility bill will speak for itself.ĭepending on the system design and usage, the break even point varies widely. It may take years to reach a break-even point. One could argue that from strictly a cost savings point of view it might not be practical. Though the costs of solar are coming down! This cell is what actually turns sunlight into electricity.It depends on your objectives! First, lets face it… To implement solar energy is not cheap compared to today’s energy from the grid. The solar cell is a fundamental element of solar power (and the building block of a solar panel). Now let’s take a look at the humble (yet powerful!) solar cell that makes solar power possible. We then provide a schematic of a solar power system that shows how to connect your solar panel, charge controller, and solar battery together. We start with a diagram of the solar cell and then proceed to diagrams of solar panels and solar arrays. So we’re going to give your ears a break by providing some relevant solar power diagrams that illustrate how solar power works. It can help you to understand how solar power works in a much more direct way than just hearing about it.Īfter all, you can only listen to an explanation of volts, watts, inverters, and solar cells so many times before it all starts to sound the same.Ī solar panel picture can break the monotony and give your eyes a chance to look at what your ears are tired of hearing about. Looking at a solar panel diagram can often be a great learning shortcut.
