Sizing A Solar Off Grid System

After we have a full model of what we’re looking to achieve in designing solar power systems and have a little background on electricity it is time to do some contemplating and a little arithmetic to turn that into reality. That takes place in 2 pieces. One, we need to know what we’re attempting to control and how much energy that’ll use. As soon as we decide on that, the next thing to do is understanding what quantity of panels and solar batteries will meet our requirements when the setup is built.

For an off-grid system like the one I built, I am only running a subset of ordinary household items and appliances. This includes a music player, a PC, lighting, a water pump and a few others. The first step is to jot down a listing of everything you anticipate powering.

The next step actually requires multiplication, just so you’re warned in advance. Understanding what you’re planning to run is fine, knowing the exact quantity of electricity that takes is what you actually want. You can find several resources on the web for that at a high level. Make a spreadsheet detailing each item, its energy consumption and the number of hours a day it’ll have to be on. Multiplying watts by hours for every component results in a daily watt*hour total, then adding all the pieces as a whole gives the overall daily amount. This is what we are interested in, total electricity usage as one value, after we reach this point each discrete component being run does not matter anymore, although you will probably go back and tweak that list a couple times.

Once we have our absolute daily power usage amount, we’ll have to be able to generate it. The number one and most important variable is going to be in what location your system is geographically. In the middle of winter at the North Pole, there isn’t any sunlight at all, but there is of course a fair bit in the Arizona desert. Because I’m planning to be in the southern US in the middle of January, I ran with the rough guess that I will be harvesting five hours of peak daylight on a normal day.

On top of this we have to take into account rainy days. I decided to use a rough worst case that it could be cloudy for three days in a row, and that clouds lessen panel input by fifty percent. This is not an exact science, and depends on your number of batteries how much you can drain them through stretches of reduced light, but basically round numbers are easier.

In a DIY solar setup the deep cycle batteries are actually equally important to providing energy as the panels themselves. When the sun sets, you have to be able to drain all the solar energy accumulated during the daytime to power your electronics. A battery bank that is not big enough will cause a couple issues. One is that it can lessen the overall life of the deep cycle batteries. Try not to drain your deep cycle batteries under half of their overall capacity. A continual usage of three quarters of the total capacity can cause the deep cycle batteries to lose capacity, not store as much charge and have to be changed a good deal earlier. Another concern with a not big enough capacity is not harvesting the total amount of free solar power. If it’s nice and sunny and you always fully refill the battery bank by mid afternoon each day, from that point until sundown you’re not getting any more power, it’s nothing but waste.

Learn How To Build Your Own Solar Panel Power System With Grid Tie Inverter

Need a step by step article on how to build your own solar panel power system for home, garage, remote property or a holiday house, than you are in the right place as I previously helped a few people to build their own. I received great feedback and some people went above and beyond and are now off grid enjoying an electricity bill free household. There is a lot of research to do before you get started and good thing you landed here reading my article because I’m happy to share with you all my research I’ve done.

I’ve posted some content with a full explanation about how it works and how I’ve connected all the components together: solar panels, wiring, switch disconnect/fuses box, power charge controller, grid tie inverter, regular power inverter, power meters/monitors, and a deep cycle battery bank.

A quick and easy start with a basic solar panel power system.
Tips on how to build your own solar panel power system with grid tie inverter

Firstly you need a solar panel to start. Recommended are the Mono-crystalline as they’re the most advanced at the moment, they have quite a long life (15-25 years). Mono-crystalline panels are made of little square cells about 5 x 5cm each, connected in series. Mono-crystalline panels can be found anywhere from 1 W to 280 W at the moment at 12 V or 24 V. It is very important to place the panels in a good spot where they will get the most sun on them and a safe and strong mounting is required as well.

Next you need some wire which recommended is the solar cable/wire with double insulation and UV protected, outdoor ready. Depending on how big you want the system to be, the more advanced equipment you find available and the more expensive it is, but we`re talking about a basic system to start with. For one of these systems you can use just a power gardening wire hidden from the sun, it will do the job.

At this point we have the panel, firmly installed with a good positioning towards the sun and wired. That`s all what you need to produce power.
How to use the power that is getting produced by the panel…

There are three ways:

1-use the power that is getting produced straight from the panels (during the day only)

2-store the power in a battery bank and use it when needed

3-export the power produced straight to your home grid (again during the day only)
List of components I’ve used with my system:
-1x 12v 100w solar panel
-1x 24v 120w solar panel
-4x 4.5kA fuses
-1x C60(60amp) Xantrex Power charge controller (12v or 24v settings)
-1x 300w grid tie inverter Power Jack – China 20v -> 240v
-1x 250w grid tie inverter Masspower – USA 20v -> 240v -2x Power Meter UK
-2x 30A fuses
-1x BitMB Power inverter 3000w continuous and 6000w peak 24V->240V DC->AC (modified sine)
-4x 150Ah 12V Deep Cycle batteries, connected in series and parallel so they work as 24V 300Ah
-1x DC 4way switch
-14x battery cables
-2x pairs PV plug
-20m outdoor electric wire

Main Photovoltaic Panel Parts

From the operators of — providing education regarding how to make a home made solar panel, solar panel kits, and how does solar power work.

One of the reasons that constructing your own photovoltaic panels has become so popular is that there are really very few parts involved. A regular solar panel consists of just a few basic parts, namely an enclosure, photovoltaic (pv), a substrate and wiring. Here’s a summary of what’s involved.

Solar panel case or enclosure
This is what most people see when they think of a solar panel. It’s the clear glass top, the frame and the backing that the photovoltaic cells are mounted on. The case can be hefty enough to need a custom built metal rack for mounting on a rooftop, or small enough to be a plastic box that can be placed almost invisibly near an outdoor floodlight. It needs to be resistant to ultra violet (UV) rays so that it doesn’t deteriorate with relentless exposure to sunlight. And the glass (usually Plexiglas) needs to be durable enough to withstand harsh weather, including hail and wind storms that could crash tree branches and other debris into it.

This is the piece of wood, peg board or other material that the solar cells are mounted on within of the enclosure. It too needs to be UV-resistant to survive prolonged exposure to direct sunlight.

Solar cells
The solar cells are comparable to the silicon chips that power most computers. They combine the silicon, metals and other materials in a way that captures direct sunlight and converts it into electricity. The electricity can either be instantly used by direct current devices (DC) like LED lights, or stored in DC batteries and transformed into alternating current (AC) to power conventional appliances like refrigerators, TVs and other electrical equipment in homes and businesses.

Tabbed and untabbed pv (photovoltaic cells
When building your own pv (photovoltaic) panels, you can save money by purchasing untabbed solar cells and soldering the tabs on top of the cells yourself. This can be a good choice if you have more time than money, but it’s a tedious job. You can save time by buying tabbed solar cells which will cut your soldering time by one-half to two-thirds.

Pv (photovoltaic) cell wiring
As soon as the solar cells are mounted on the substrate, they are wired to each other in a series so that they can generate electricity. Copper wire is added to connect the solar cells to storage batteries for using the electricity later, or to connect directly to the device that the solar panel is powering like an attic fan or a solar powered toy.

Blocking diode

The blocking diode is a little component that prevents electricity that is stored in a battery from draining backward into the pv (photovoltaic) panel. Bigger photovoltaic systems use a charge controller for the same effect.

Must You Construct Your Own Solar Swimming Pool Heater?

From the operators of — providing education regarding how to make a homemade solar panel, solar powered, and solar hot water.

Building your own solar swimming pool heater is a fantastic do-it-yourself project if you want to add solar to your house.  You will not need to buy a lot of high-priced equipment or tools.  And you will not need highly specialized skills.  Here is a fundamental explanation of the process and benefits so you can decide if you want to tackle it.

The project payback time can be as short as 2 years in terms of energy savings.  This is because you will be saving the cost of gas to heat your pool.  And the cost of materials for building a solar pool heater is lower than with most other solar projects. You will also be saving the cost of installation if you decide to go ahead and do that yourself.

You will need to buy only a few simple components: solar collectors, piping, a controller and a diverter valve.  You will not need to build or buy a storage container, since your pool already stores the water.  And you will not need to get, build or install a circulating pump, since your solar pool heater will use your pool’s circulating pump.

Here’s a straightforward explanation of how the system works.  The water from the pool gets pumped into the solar collector, gets heated by the sun and gets pumped back into the pool. This is called an open loop design.  The controller allows you to select the warmest temperature you want the pool to reach.  And the diverter valve either sends water back to the pool if it is already warm enough, or over to the collector to be heated as required.  

The solar collector is a simple system of black polypropylene UV-resistant tubing.  The choice of materials is important so that the tubing doesn’t break down from exposure to the sun or from exposure from the chlorine in the pool.  The suitable materials will last up to 20 years.

Although it is attractive to think of doing it all yourself, including making the solar collector, it is really easier and more cost effective to purchase ready made collectors for your project.  The reason is that adhesives will not stick to polypropylene, and the equipment you would need to thermal weld it would cost more than buying the ready-made collectors.  What’s more, experts advise against using a cheaper rubber or plastic tubing that will break down too quickly because of exposure to the sun and chlorine.

If you decide that you really want to install your solar pool heating system yourself, the easiest method is to buy a kit.  You will still need to design measure and install your system.  And you will be able to enjoy the fruits of your efforts for years afterwards.

Solar PV – Make Your Own Personal Electrical Power For The Destiny Of The World

Solar PV certainly are a series of solar cells which have inside of it components which could transform photo voltaic radiation directly into direct current electricity. Much more particularly it can be that technological innovation which could convert sunlight directly into electrical power. The actual sun’s rays can provide around a thousand volts involving electricity in every block meter of the earth’s surface on a sun-drenched day. In case most of that power could be makes use of most people would be able to power some of our property at no cost.

The use of solar power system is usually diverse. You can use it to create electrical power in the home, in order to electrical power the electric motors, as well as block lights to name just a few. Photovoltaic happen to be used dating back 1958, having said that; its practical application had been typically within area. These are most generally utilised presently in solar energy hand calculators in which will need only daylight to operate.

Photo voltaic cells possess materials also known as semiconductors which are silicon and also are most frequently made use of. When daylight sinks into the cell part of in which light can be absorbed inside the semiconductor material. Energy for the reason that daylight might be used in the semiconductor which loosens electrons which in turn amount readily within the certain path. This particular flow associated with electrons is actually a current that can be used as electric power as soon as metal associates will be placed at the pinnacle along with bottom of the Photo voltaic cell. The current and also the cell’s voltage tell us the amount of wattage the particular solar cell could make.

Using solar power isn’t yet prevalent adequate to locate everyone using it but there are many people that feel they are able to help the environment while using solar Photovoltaic. Together with the price of electricity on the rise as well as the economy spiraling downward, people are curious about saving on their utility bills or totally eliminating them while using solar energy. Photovoltaic is usually an alternative power generating resource that can save money as well as do its part in preserving the planet. There is much talk about global warming and the greenhouse effect and also using solar PV, as an alternative power source, could make us feel good about ourselves once we do our part.

Now we’ve seen in the very last years elements just like the prices of the petrol crud oil barrel which have been getting to new peaks, the catastrophic effects of our planets atmosphere as a result of emission involving co2 leading to severe warmth as well as frosty waves along with various other unbelievable catastrophes, and more recently the horrible leak inside the Mexico bay eradicating the life of so many folks and also killing all of the faun within the area, its about time to take action and cease depending on fossil gas. Looking at additional directions is really a possibility. For example if only twenty percent from the Sahara desert has been coated with solar PV then it could supply 100% of the entire world electric utilization. Power from the sun is a resource that won’t finish anytime soon, long term and 100 % free to utilize by anyone. There is actually a need to make a worldwide move of mindset and find conscious that it could help save our own kids planet.
