The occasion was formally celebrated at a sod turning ceremony at the entry to the solar farm site, about 6km northeast of Uralla. More than three dozen workers are now on-site undertaking earthworks and road and drainage construction across nine kilometres of local roads before work can begin on the solar farm site.
The solar farm construction and road upgrades are being led by Green Light Contractors with the road design, survey and construction being undertaken by locally based businesses that have expanded their local workforce to support the project.
Vuild New England based surveying and engineering businesses have completed survey work for the site, as well as plans for the onsite operation and maintenance how to fix burnt gravy. Mr Rohner said the project would continue sopar drive opportunities for local businesses, employment and pane, grow the local economy.
They are expected to take about three months to complete. They will allow safe access for construction on the solar farm site, which is expected to begin towards the middle of the year. The New England Solar Farm and battery project will be built in two stages.
The solar farm will connect with the existing kV transmission power line that crosses the site. Once fully constructed, the project is expected to produce 1,MWh of clean, renewable electricity each year; enough to t more thantypical NSW homes.

Wire the solar panel: At the back sides of the solar panel there is a small junction box 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 panels you have to connect the junction box with external wires. A solar farm is a large land area where multiple ground-mount solar tracking towers are installed. Usually, it can be on a working farm or other open and mostly unimproved land. The Solar Farm Developers industry is made up of companies that mainly install and construct solar power grid systems, which is known as solar farms, on a utility scale. Aug 11, · A solar panel business will conduct on-site surveys of potential installations, create a solar plan for the location, work with the owner on financing and install the units. Maintenance positions within the company provide support for the new owners repairing and maintaining panels to ensure greatest productivity and return on the investment.
Day by day the price of solar panels falls gradually. But still, installation of a complete off grid solar system is costly. If you have decided to install a solar panel system to cover your home power needs, then 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. You have to know some basic electrical and math for designing the entire system.
I have also attached links of my other instructions 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. Before choosing the components you have to calculate your power load, how much time it will run, etc.
It is very simple to calculate if you know basic math. Now the load calculation is over, next thing is to choose the right components to match your load requirement. If you are not interested in doing the above maths then use a load calculator for this calculation.
There are many such load calculators available in the internet, for example this Off Grid Load Calculator. The output from the solar panel is dc power. This power is generated during day time only. So if you want to run a dc load during day time then it seems to be very easy.
But doing this is not a good decision because…. The above problem is solved by using a battery to store the solar power during the day and use it according to your choice. It will provide constant source of stable, reliable power. There are various kind of batteries. Car and bike batteries are designed for supplying short bursts of high current and then be recharged and are not designed for a deep discharge.
But the solar battery is a deep-cycle lead-acid battery that allows for partial discharge and allows for deep slow discharge. Lead acid tubular batteries are perfect for a solar system. The higher the voltage, the lesser the current and the lesser the copper loss will be in the conductor.
This will also reduce your conductor size. Most of the small home solar systems will have 12 V or 24 V. Solar panel ratings for the W solar panel. The Solar Panel converts the sunlight into electricity as direct current DC. These panels are typically categorized as mono crystalline or poly crystalline. Mono crystalline are costlier and more efficient than poly crystalline panels. The solar panel size should be selected in such way that it will charge the battery fully in one sunny day.
During the 12hr day time the sunlight is not uniform, and it also differ according to your location on the globe. So we can assume 4 hours of effective sunlight which will generate the rated power. A solar charge controller is a device which is placed between a solar panel and a battery. It regulates the voltage and current coming from your solar panels. It is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar panel rises, the charge controller regulates the charge to the batteries preventing any over charging.
Usually, the solar power systems uses 12 volt batteries, however solar panels can deliver far more voltage than is required to charge the batteries. By, in essence, converting the excess voltage into amps, the charge voltage can be kept at an optimal level while the time required to fully charge the batteries is reduced. This allows the solar power system to operate optimally at all times. Among the 3 charge controllers MPPT have the highest efficiency but it is also costly. If you like to reduce your system cost you can make your own PWM charge controller.
You may also like my new 3. DC is then converted into alternating current AC through a device called an Inverter. AC electricity flows through every outlet of your home, powering the appliances. Square wave inverters are the cheapest but not suitable for all appliances.
Modified Sine Wave output is also not suitable for certain appliances, particularly those with capacitive and electromagnetic devices such as: a fridge, microwave oven and most kinds of motors. Typically modified sine wave inverters work at lower efficiency than pure sine wave inverters. It may be grid tie or stand alone.
In our case it is obviously stand alone and completely off-the-grid. Note: Appliances like fridge, hair drier, vacuum cleaner, washing machine, etc. This should be taken into account when choosing the right size of inverter. After designing the solar system, buy all the components with appropriate rating as per the previous steps. Now it is time to mount the solar panel. First choose a suitable location on the roof top, or on the ground, where there is no obstruction of sunlight.
Prepare the mounting stand: You can make it by your own or buy one. In my case I have taken the drawing from the solar panel company and made it at a near by welding shop.
The tilt of the stand is nearly equal to the latitude angle of your location. I made a small wooden mounting stand for my 10 Watt solar panel. I have attached the pictures, so that any one can make it easily. Tilting : To get the most from solar panels, you need to point them in the direction that captures the maximum sun light, i. You also have to optimize the angle relative to the ground. Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted:.

I roughened up the surface at each leg of the stand by using a sharp object. I made around a 1 square feet size rough surface on the roof at each leg. This is helpful for perfecting the 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. You can of course secure it into place using other methods than concrete, this is just an example of a solution for my specific situation.
Mount 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 there is a small junction box 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 panels 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 calculating the battery capacity and solar panel rating you have to wire them.
In many cases the calculated solar panel size or battery is not readily available in the form of a single unit in the market. So you have to add a 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 connections. 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.
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 the sum of all the devices. Similarly if two solar panels of 17V and 5 amps are connected in parallel then the system will produce 17 Volts, 10 amps. I made the above inverter and battery stand with the help of a carpenter.
The design idea I got from this instructable. The design was really helpful to me. At the back side I made a big circular hole just behind the inverter fan for fresh air suction from the outside. Later I covered the hole with plastic wire mesh.
A few small holes are also made for inserting the wires from the solar panel, charge controller and inverter to the battery and AC output to the appliances.
At both sides 3 horizontal holes are provided for sufficient ventilation. A glass window is provided at the front side to view the different led indications on the inverter. In the inclined plane of the inverter stand I have mounted the charge controller.
