NOTE: For special circumstances or for more information about any of our off-grid solar power kits, please call An off-grid solar power system captures energy from sunlight and stores it in a battery bank for use in a structure which is beyond the reach of the main power grid.

Using solar panels to create an elecrical DC current, this current is then routed through a solar charge controller which ensures proper charging and prevents overcharging and helps to "float" the battery bank, meaning to keep the charge topped-off. The current is then directed to the battery bank for storage and later use. In most off-grid solar installations, the current is drawn from the battery through a DC-to-AC solar inverter.

The AC current is then used to power household appliances and, together with a good energy usage plan, can power many of the needs of an off-grid home or other structure. We have taken great care in the design of our pre-packaged off-grid solar power systems.

So I write this instructable to get all the components of your solar system separately and assemble it all by yourself. If you are decided to install a solar panel system to cover your home power needs. This tutorial is for you. I have tried my best to guide you step by step from buying different components to wiring everything by yourself.

Only you have to know some basic electrical and math for designing the entire system. Instead of this, I have attached links of my other Instructables to make the charge controller and energy meter. Besides the above components you need a few more things like Copper Wire, MC4 Connector, breaker, meter, and fuses, etc. In the next few steps, I will explain in details how you can choose the above components according to your requirement.


But during the calculation, I have taken a smaller solar system example for better understanding. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.

Before choosing the components you have to calculate what is your load, how much time it will run etc. If anyone knows basic maths then It is very simple to calculate. Calculate the Watt Hour which is equal to the product of power rating of your appliances and time hr of the run. Now the load calculation is over. The next thing is to choose the right components to match your load requirement.

If you are not interested to do the above maths then use a load calculator for this calculation. You can use this nice Load Calculator. The Solar Panel converts the sunlight into electricity as direct current DC.

These are typically categorized as. Monocrystalline is costlier and efficient than the polycrystalline panel. The solar panel size should be selected in such a way that it will charge the battery fully during the one day time.You can edit the text in this area, and change where the contact form on the right submits to, by entering edit mode using the modes on the bottom right.

Off-Grid Solar Power Systems

Plus hybrid inverters, battery sizing, Lithium-ion and lead-acid batteries, off-grid and on-grid power systems. All solar power systems work on the same basic principles. Solar panels first convert solar energy or sunlight into DC power using what is known as the photovoltaic PV effect. The DC power can then be stored in a battery or converted by a solar inverter into AC power which can be used to run home appliances.

Depending on the type of system, excess solar energy can also be fed into the electricity grid to provide credits and further reduce electricity costs. On-grid - also known as a grid-tie or grid-feed solar system.

Off-grid - also known as a stand-alone power system SAPS. Hybrid - solar plus battery storage with grid-connection. First we will describe the common components used by all three types before going into more detail about the different systems and how they work. Most modern solar panels are made up of many silicon based photovoltaic or PV cells which generate direct current DC electricity from solar energy.

The individual PV cells are linked together within the solar panel and connected to adjacent panels using DC cables. Note : It is light energy or irradiance, not heat, which produces electricity in photovoltaic cells. The amount of solar energy generated depends on a number of factors including the orientation and tilt angle of the solar panels, efficiency of the solar panelplus any losses due to shading, dirt and even ambient temperature.

There are many different solar panel manufacturers on the market so it worth knowing which are the best solar panels and why. Some of the many different types of solar panels available - Learn more about the best solar panels. Solar panels can generate energy during cloudy and overcast weather but the amount of energy depends on the 'thickness' and height of the clouds, which determines how much dispersed light can pass through.I am really found of solar energy and my dream is to shift my house consumption totally on renewable energy.

In On-Grid system solar panels are placed on the rooftop ,The electricity generated by the solar panel is direct current and the electricity we use in our houses is alternate current so to convert DC to AC we need an inverter to convert it. But as the system have to connect with the grid so we require Grid Tie inverter which will convert the DC to AC in the same frequency as we are getting it from our energy provider company.

The Grid tie inverter is connected to our mains through a solar meter which will just calculate the solar unit generated, Than the the connections are made with the NET METER, which calculate the units consumed from the electrical company and also have the data about the solar unit generated. Suppose we have placed a solar Grid tie system of Wand in the morning around 11 Am, The system is producing W.

The consumption in our house is w consumed by fan, LED tv. And Suppose if we have a party our place in morning and our consumption reaches to W so our solar system will provide us with W and the remaining W will be supplied by the electrical energy company. In ON-GRID system suppose we are out for the day and our system generates 12 units and in the evening when we reach home and switch on the Air condition and light so we can use the same amount of unit at night.

The solar panels are made up of photovoltaic PV cells, which convert sunlight into direct current DC electricity throughout the day.

This device converts the DC electricity generated by the solar panels into the alternating current AC electricity. The AC electricity is sent from the inverter to your electrical panel to power your lights and appliances with solar energy. The electrical panel is often called a "breaker box. The utility meter measures your energy use. It actually goes backward when your system generates more power than you immediately need.

This excess solar energy offsets the energy you use at night. Your business is still connected to the grid. The cost is offset by any excess solar energy you put into the grid during the day. Power Guide monitoring system continuously tracks your energy production and ensures that your solar power system is running smoothly.

In my case i wanted to install the complete W solar system but due to shortage of funds i am installing 3 KW of grid tie inverter and W solar panels for now, in the future i will double the solar panel accordingly.

In AC wire the inner gauge of wire is lower approx to 15 where as in DC wire the gauge of wire is higher around So in this step we will understand the load calculation of our house, which will give us an idea of the wattage of system we require. So we get the wattage of each appliances, We must know that these appliances will consume this much wattage in 1 hour so to get the consumption of our day, we will multiply the hours usage with the particular appliances wattage.

Answer is : 1 kw of panels produces 4 units in a day, when we will divide our daily consumption with the 4 than we will get the wattage of panels that we want to install like. Now on yearly basis and based on tropical region this calculation changes as some countries have more sunny hours and some have less.

In this step we calculate the rooftop area which is available for installing solar panels, 1 kw of solar installation requires 80 Sq ft Sq ft of area. The difference of 20 Sq ft is because of the cleaning space a person requires to clean panels.

In my case i have approx 50 sq ft of space available for the installation of w so i have decided to up lift the structure by 8 ft and extend the structure outside my roof boundary, It is legal as the boundary of solar panels comes under the fence of my roof.

But i will recommend you to install the panels close to the roof surface as it will be easy for you to clean the panels after installation, in my case it is a challenge but i can utilize the space below the panels for plants.

D esigning of structure is the main process as you have to make to withstand for more than 20 years. In my case i am using the iron angles of 50 mm x 50 mm x 5 mm as it will provide more strength to my structure, The main point that we have to keep in our mind is the solar panel facing and its tilt angle.

As we all know sun rises from east and goes to west, so our solar panel face would be gr8 toward south.Toggle navigation. Help Preferences Sign up Log in. View by Category Toggle navigation.

What would be the best in your situation? Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept — a solar system that is connected to the utility power grid. A grid-connection will allow you to save more money with solar panels through better efficiency rates, net metering, plus lower equipment and installation costs:.

Batteries, and other stand-alone equipment, are required for a fully functional off-grid solar system and add to costs as well as maintenance. Grid-tied solar systems are therefore generally cheaper and simpler to install.

Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries. Net metering or feed-in tariff schemes in some countries play an important role in how solar power is incentivized. Without it, residential solar systems would be much less feasible from a financial point of view.

Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves. Electricity has to be spent in real time. However, it can be temporarily stored as other forms of energy e. Energy storage typically comes with significant losses. The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates.

In other words, more electricity and more money goes to waste with conventional battery systems. Additional perks of being grid-tied include access to backup power from the utility grid in case your solar system stop generating electricity for one reason or another. As a result, the efficiency of our electrical system as a whole goes up. There are a few key differences between the equipment needed for grid-tied, off-grid and hybrid solar systems. Standard grid-tied solar systems rely on the following components:.

What is the job of a solar inverter? They regulate the voltage and current received from your solar panels.
