GRID TIE INVERTER SOLAR panel POWER EASY Electricity Savings

Day by day the price of the solar panel falls gradually. But still installation of a complete off grid solar system is costly. 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.

To get the south direction use this android app compass. Then make rough surface at each leg of the stand by using a sharp object.

I made around 1Sq feet size rough surface over the roof at each leg.

This is helpful for perfect bonding between the roof and concrete. Prepare concrete mix : Take cement and stones with ratio then add water to make a thick mix. Pour concrete mix at each leg of the stand. I made a heap shape concrete mix to give maximum strength. Mounts the panels to the stand : At the back sides the solar panel have inbuilt holes for mounting. Wire the solar panel : At the back sides of the solar panel a small junction box is there with positive and negative sign for polarity.

In a large size solar panel this junction box have terminal wires with MC4 connector but for small size panel you have to connect the junction box with external wires. Always try to use red and black wire for the positive and negative terminal connection.

If there is provision for earth wire the use a green wire for wiring this. After the calculating the battery capacity and solar panel rating you have to wiring them. In many cases the calculated solar panel size or battery is not readily available in the form of single unit in the market.

So you have to add small solar panel or batteries to match your system requirement. To match the required voltage and current rating we have to use series and parallel connection. To wire any device in series you must connect the positive terminal of one device to the negative terminal of the next device.

The device in our case may be solar panel or battery. So if these devices were batteries and each battery had a rating of 12 Volts and Ah then the total value of this series circuit would be 48 Volt, Ah. If they were solar panels and each solar panel had a rating of 17 volts Osc voltage and were rated at 5 amps each then the total circuit value would be 68 volts, 5 amps.

How do you hook up a solar panel to your house

In parallel connection you must connect the positive terminal of the first device to the positive terminal of the next device and negative terminal of the first device to the negative terminal of the next device. In parallel connection the voltage is remain same but the current rating of the circuit is sum of all the devices. Similarly if two solar panel of 17V and 5 amps are connected in paralel then the system will produced 17 Volts ,10 amps. I made the above inverter and battery stand by the help of a carpenter.

While the technology behind solar energy seems complex, when broken down, how solar power works is easy to understand. This is particularly so with grid. Our solar experts will help guide your DIY home solar panel installation. your state, and plan to have an electrician or licensed contractor do the final hook-up. So, you're interested in getting a solar panel system for your house? A engineer had to actually climb up on my roof, take measurements.

The design idea I got from this instructable. The design is really helpful for me. At the back side I made a big circular hole just behind the inverter fan for fresh air suction from out side.

Later I covered the hole by using plastic wire mesh. Few small holes are also made for inserting the wires from solar panel,charge controller and inverter to the battery and ac out put to the appliances.

At the both sides panel 3 horizontal holes are provided for sufficient ventilation. A glass window is provided at the front side to view the different led indications in the inverter. In the inclined plane of the inverter stand I have mounted the charge controller. In future I will installed my own made energy meter also.

The first component we are going to wire is the Charge Controller. At the bottom of the Charge Controller there are 3 signs in my charge controller. As per charge controller manual always connect the Charge Controller to the Battery first because this allows the Charge Controller to get calibrated to whether it is 12V or 24V system. After connecting the battery with charge controller you can see the Charge Controller indicator led lights up to indicate the Battery level.

After connecting this inverter terminals for battery charging is connected to corresponding positive and negative terminals of the battery. Now you have to connect the solar panel to the charge controller.

How to Install Home Solar Storage

The terminal wires are normally smaller in length. To connect the wire to the charge controller you need a special type connector which is commonly known as MC4 connector.

See the picture. After connecting the solar panel to the charge controller the green led indicator will light if sunlight is present.

HOW A GRID CONNECTED SOLAR POWER SYSTEM WORKS

Note : Always connect the Solar Panel to Charge Controller while facing the Panel away from the sun or you may cover the panel with a dark material to avoid sudden high voltage coming from the solar panel to the Charge Controller which may damage it. If it gets mixed up, the equipment can go burst and may catch fire.

So you need to be extremely careful when connecting these wires. It is recommended to use 2 color wires i. If you don't have red and black wire you may wrap red and black tap at the terminals. Connect the dc load or dc light at last. Additional Protection : Though charge controller and inverter have inbuilt fuses for protection, you can put switches and fuses in the following places for additional protection and isolation.

In between solar panel and charge controller 2. In between charge controller and battery bank 3. In between battery and inverter Metering and Data logging : If you are interested to know how much energy is produced by your solar panel or how much energy being consumed by your appliances you have to use energy meters. Besides this you can monitor the different parameters in your off grid solar system by remote data logging For diy based energy meter you can see my instructable on ENERGY METER which have both metering and data logging capability.

After wiring every thing the off grid Solar system is ready for use. This is a simple design worksheet for stand-alone solar PV systems. It explains the design process and explains some of the practicalities of building a system. I hope it will be useful. The full credit goes to the authors of Re-Innovation. Very useful workbook for design Solar off-Grid power plant. Helpful for beginners, Learners and trainers to train trainees.

How to Solar Power Your Home

Krishna shrivastava I am not an electrical engineer so many of the articles already on Instructables on this subject or on the internet seemed incomplete to me because they did not explain many of the details that you did. Perhaps for the electrically inclinded those finer points are common knowledge and not necessary, but for me it exactly what I needed. The step-by-step approach with explanations and links to products was fantastic. I have never written an Instructable but I appreciate all the time and effort it requires to write something like this, so thank you very, very much.

Reply 2 months ago. Glad my work is helpful for you. Your kind words really motivate me to write an article like this in the future. Thank you so much. Reply 7 weeks ago. Question 2 months ago on Introduction. Answer 2 months ago.

Question 9 months ago on Step 9. We need to move our solar panels well away from trees. The optimal place is about metres away from the batteries.

Is this distance going to be a problem?

Answer 4 months ago. Hi Louise.

For high distant instalations, it is advised to use higher Voltage systems. Higher the voltage, lower the transmission losses and lower the cost of wireing. Question 7 months ago.

Does anyone know if it would be OK to house the batteries outside in an insulated box? If it stayed dry, could the controller also stay outside?

DIY OFF GRID SOLAR SYSTEM: Day by day the price of the solar panel falls gradually. Besides the above components you need few more things like Copper Wire, .. The second one with plus (+) and minus (-) sign is for the Battery connection . to keep the batteries charged the whole time the house is draining power. Once you're ready, install the solar panels. If you live in an area where AC power is used, you'll need to connect your solar panels to an These would connect separately to your house and.

Question 11 months ago on Introduction. Answer 11 months ago. That is a good guess, but I think, c ompact f luorescent l amp, is a more likely fit, for the discussion in this 'ible. Is there any way to build a system that pulls from a battery first, and then would pull from the grid after you used up all the electricity that got stored throughout the day from solar? Reply 12 months ago.

Are you in the US? You can install solar panels and feed them into the grid if so. By law the power companies have to buy any electricity you produce. In some states it's much easier to implement than others though, check with local solar companies. You always use off the grid, but whatever you produce is fed into the grid during daytime. That offsets your electric bill. In most states the electric company just gives you a credit for whatever you produce, not a check in the mail.

There are automatic switches for generators that switch from grid to generator during a power outage. Shouldn't be hard to create something similar that will auto switch over when battery level is down. Those auto power outage switches aren't cheap though. Controlling the switch could be done with an Arduino or similar controleer, but you'd still need the heavy duty switch to switch over the load. Important consideration: when you are selling your solar power into the grid the IRS gets involved and you will PAY taxes for the wonderful earnings of your solar array.

If you are looking at ROI for your grid-tied system it might be a small thing or a large thing depending on your situation so just be aware especially if you are trying to save money over time.

Off grid electrical panel #rustichouse Building A Container Home, Container Houses. Solar power is increasingly gaining popularity as a reliable and clean energy source for the home. Initially, you may find solar cells expensive, so you may use . I want to build a homemade solar panel (several actually) but once it's made, how do you hook it up to your home for power/feed into the grid to.

Now at night when you draw energy from the grid Hey, one thing i see all the time with solar projects is all anybody uses is 12v deep cycle batteries. These batteries were mostly meant for boats, high cranking amps and could be discharged more without killing the life of the battery.

The best battery to use is deep cycle 6v batteries wired in series to give you one big 12v battery. If you want lots of power stored for longer use, use 6v batts. Another thing that you need to think of if you are going off grid is your solar array needs to be big enough to not only run the things you want but also put out enough power to recharge the batteries at the same time or each time you start to use the batteries they will just be drained more and more until they are dead.

System needs to be bigger than for just running the house.

If you are totally off grid then your system needs to keep the batteries charged the whole time the house is draining power. Same thing either way you look at it. Reply 2 years ago. Thanks for the information, please i have a question if i am to use 2 6V instead of 1 big 12v battery, does the AH size matters? Having made something similar though not yet solar powered the capacity doesn't matter as long as both series batteries are the same.

Which is why I use 12v fire alarm rated sla batteries instead. My total capacity on 12v is around Ah about wh By Open Green Energy Follow. More by the author:. For a off grid solar system you need four basic components 1.

Solar Panel PV Panel 2. Charge Controller 3. Whenever the sun shines and even in overcast weatherthe solar cells generate electricity. Some electricity companies meter the electricity fed into the grid by your system and provide a credit on your bill.

How much you are paid is determined by the feed-in tariff. When the solar cells are not producing power, for example at night, power comes from the mains power grid as usual. As all components in a system have no moving parts, you can expect a long hassle free life from your solar power system! Most customers choose a roof mounted solar power system. However a west facing installation may also be desirable. This positioning may provide power at the time of the day when there is most demand.

Our accredited grid connect installers will aim to install the modules at an angle which ensures that the glass face of the modules is positioned at 90 degrees to the sun for most of the day. As an example, in Sydney this angle would be approximately degrees to the horizontal.
