Which direction should solar panels face

But, if you’re willing to pare down to the bare essentials, you can break free from the electrical grid and begin a life of energy independence. Those who are already living out of their cars, vans, or mobile homes have a head start on this, and can put these ideas to use immediately. Steps 1 If you have a car, get yourself a solar trickle charger to keep the battery topped off whenever the sun is shining. This is a good first step in the right direction; as long as the PV panel is 20 watts or less, there is little danger in over-charging the battery and the resultant boil-off of the electrolyte even without a charge controller. Many “boom boxes” accept 8 cells, which means 12V; you can make battery eliminators and run these directly off your car battery. With one of these, you can extend your range of wifi access significantly, so you don’t have to go without WikiHow as you learn energy independence. Many devices and tools that nominally run off 6V to 24V will run off 12V, although it can be very risky to run a 6V device at double its rated voltage.

DIY PV System Installation

Email Advertisement Remember when solar power was snickered at? Now, huge companies like Google The Oil Killers: Innovation comes at a cost.

The solar company should give you an estimate of how much power that system is going to produce based on annual statistics they know from a variety of different factors: the weather in your region.

I used a 6 by 6 by 6 metal box for this. The junction box out at the array. The grey PVC conduit goes to the house. The black cord comes from the first in the line of micro-inverters. The junction box is supported on MDO plywood, which is very water resistant — its what freeway signs are made of. I did this wiring before connecting the micro-inverter cables to the PV panels, and before connecting the new circuit breaker to the house power, so there was no power applied to this circuit during the wiring from either the PV end or the house power end.

You will need one of these. The wiring connections in the junction box are: The grounding lug should be attached to the box with a self tapping screw so that it makes good electrical contact with the box.

Outdoor Home: Why Not Build a Solar

A solar shed can add new life to your backyard Image via: Cottage Life Examine the Setting and Equipment Before you go out and buy a solar panel , you need to know if your backyard gets enough sunlight. A solar pathfinder can help you to determine whether the shed roof will get sufficient sunlight throughout the day. A solar panel that gets about hours of sunlight can power basic workshop tools.

Buy the right solar garden shed kit to suit the location and direction of sunlight. The solar panels you get for your shed must be photovoltaic.

You can calculate how many solar panels you need by multiplying your household’s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel’s wattage. Use a low-wattage (W) and high-wattage (W) example to establish a range (ex: panels to generate 11, kWh/year).

October 13, It is relatively easy to install, costs nothing to operate once installed and works pretty much anywhere. There is also abundant sunlight available for conversion to electrical power. The one problem with solar is its cost: Even so, solar is still the king for alternative power. Many preppers use it, as it allows going off-grid for your electrical power needs, without a major power plant or supplies of fuel.

In a survival situation, it is probably the most reliable source of electrical power, especially when used in conjunction with a battery backup system. All you need is some simple tools and the ability to solder. A solar panel consists of a number of solar cells, connected and mounted together, so that they produce a useable output.

How Do You Hook Residential Solar Panels to the Grid

Share Tweet Our electrician neighbor came over last night to help us install a power transfer switch. We needed this switch to enable us to switch from solar power to generator power when we go off-grid. There will be times when we want to use more electricity than our solar can provide like when I use the washing machine to wash quilts, when I need to vacuum , if we need to pump a large amount of water from the well, etc.

Until we completely disconnect from the grid, we can use the power transfer switch to alternate from grid power to solar power.

They contain everything you need to hook up your generator to your house. More importantly, power transfer systems energize entire circuits instead of appliances. They can power hard-wired appliances – like air conditioners, furnaces, security systems, and lights.

What types of panels does Make It Right Solar use? We have also used a Lumos module with a clear backsheet. Back to Top Do you have a preference? It depends on the project. Smaller roofs need higher efficiency panels. Higher efficiency panels are able to harness more energy in a smaller area — but high efficiency panels increase cost. As the industry has matured, manufacturing quality is improving and solar panels are becoming more like a commodity rather than a specialized product.

How do you attach your panels to the roof? It depends on the project and panel type: On asphalt shingles, we use quick mounts that are fully flashed and attached to rafters. For thin film on a standing seam metal roof or TPO roof, we use a peel and stick system that is applied directly to the panel. What installers have you used in Louisiana? We have worked with more than 20 different solar installation companies based in Louisiana. Back to Top Do you do individual houses?

Solar Panel Wiring

Let’s suppose the cables we connect to our solar panels are going to have a 1. The total resistance of our cable will be 20 x 0. This means that the voltage at the charge controller end of the cables will be 4. This voltage drop is irrespective of the voltage we are using, it is caused by the current and the resistance. If you are still in the design stage of your system, you may consider using a higher voltage system.

You can connect pairs of panels in series (sometimes referred to as a string), connecting the positive terminal of one panel to the negative of the next, to increase the voltage. The effects of Partial Shading on overall efficiency should be taken into account when considering series wiring.

The first thing I did was recruit the Survival Husband to do the heavy lifting. Then, together, we decided that we would install the solar kit on the roof of our garage which was angled just right and facing the south. During the summer months, we should get six to seven hour of sun a day in this location. We also agreed that climbing the roof was a task for someone younger — a lot younger — so until my brother and my electronics wizard nephew come to visit, we set things up on our upper patio and to heck with the patio furniture.

It also includes all of the parts you will need: Everything is included for a ground level installation. On the other hand, a roof top installation will require some brackets — something we have not purchased yet.

Basic Tutorials: Power Inverters for Solar Energy Systems

Are you sure you want to delete this answer? Yes Sorry, something has gone wrong. Answers Rating Newest Oldest nowing what to do with unused renewable electricity is always a dilemma — hooking up to the grid has to be the preferred option. If your residential home is grid tied, i. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid.

You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour.

Basically, as you get closer and closer to the equator, the more you want your solar panels to face straight up, and vice-versa, as you get closer to the poles, you want to aim them lower in the sky, but still toward the equator.

COM website is gone. I do not know what you will get if you order this item, but I do know that you will not get a watt grid-tie solar system that plugs into an outlet. First off, I can almost guarantee that no matter what you get, it will not include a watt solar panel. There is a good reason for this — a watt solar panel would be so large about 50 square feet that you would have to ship it extremely carefully! So maybe they meant they would send you two watt panels… The best case scenario is that you will get a Solar-in-Box clone.

This seems very unlikely since I have never heard from the Solar Liberator people, and based on their Indiegogo site they do not seem to have a deep understanding about how this stuff actually works. Maybe a box with a solar panel, a charge controller, and AC charging adapter, a battery, and an inverter tossed in. Most likely you will just wait a very long time to find out that there are all kinds of unforeseen design and production problems and you will end up getting nothing or at least nothing like what you were promised.

How do I know this? There are lots and lots of signals I can point to looking at the pitch page, but the one I want to highlight here is simple — you can not make a safe residential plug in grid-tie system. If one of the circuits in your house starts drawing more power than the wires on that circuit can safely handle, the breaker or fuse turns off the circuit before anything gets hot enough to start a fire…. If you add a solar system that feeds power into an outlet on that circuit, you prevent the breaker from seeing and sensing the overload and cutting power.
