Grid Connect vs Stand Alone Solar Power Systems

For most of Australia, the modules should be installed facing north in order to take full advantage of the sun; however a west facing installation may also be desirable. 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. This provides a close approximation to the position in which a solar array produces its maximum output. For installations on flat roofs an elevated array frame allows the solar modules to be installed at an angle of elevation of approximately 30 degrees from the horizontal. You then receive a credit for any power that your system supplied to the grid. During the night when your system does not produce and electricity you draw your power from the grid and your electricity meter measures your consumption.

Therefore even though you have a solar system during a blackout you will not have power available. If you want to keep on having electricity available during a blackout then you would need to have back up batteries installed as well, which will add to the cost of the system. Usually the inverter is placed alongside the fuse box. Solar panels take light from the sun and make electricity.

Solar hot water systems take heat from the sun and heat water. It is easy to remember:. Case studies Casuarina Square - 1. General grid connect solar power FAQ What is a grid connect solar power system? What can affect the amount of solar energy received?

Carbon emissions and climate change What about the energy it takes to produce a solar power system? How much of a reduction in carbon dioxide emissions will I achieve? This is important for maintenance, troubleshooting and protection against electrical fires.

You will need an inverter to convert DC to AC for all other electrical appliances. Off-grid inverters do not have to match phase with the utility sine wave as opposed to grid-tie inverters. Electrical current flows from the solar panels through the solar charge controller and the bank battery bank before it is finally converted into AC by the off-grid-inverter.

It takes a lot of money and big batteries to prepare for several consecutive days without the sun shining or access to the grid. This is where backup generators come in. Generators can run on propane, petroleum, gasoline and many other fuel types. Backup generators typically output AC, which can be sent through the inverter for direct use, or it can be converted into DC for battery storage.

Hybrid solar systems combines the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage. Hybrid solar systems are less expensive than off-grid solar systems. Off-peak electricity from the utility company is cheaper than diesel. The introduction of hybrid solar systems has opened up for many interesting innovations. New inverters let homeowners take advantage of changes in the utility electricity rates throughout the day.

Solar panels happen to output the most electrical power at noon — not long before the price of electricity peaks.

Your home and electrical vehicle can be programmed to consume power during off-peak hours or from your solar panels. Consequently, you can temporarily store whatever excess electricity your solar panels in batteries, and put it on the utility grid when you are paid the most for every kWh. Smart solar holds a lot of promise. The concept will become increasingly important as we transition towards the smart grid in the coming years. Hybrid solar systems utilize batter-based grid-tie inverters. These devices combine can draw electrical power to and from battery banks, as well as synchronize with the utility grid.

The bottom line is this: I have an idea that I am struggling to find any resources to back it. First of all I graduated last year with master in renewable energy from Warsaw university of technology. I work currently in the UK, but very soon will be returning to Poland as my employer is going under. Before I tell you about my idea, we can agree that there are 3 main types of domestic solar systems;. You mentioned these three types in your article. Now in order to have grid tied or hybrid system you need to know that your utility company will buy the excess energy otherwise you will b dumbing this energy for free in the grid right?

The reason is that we have to build a very large system to provide enough power during winter. Now my idea is to build a system that stands alone, but have the flexibility to switch over to utility power when we run out of juice. The system that I am thinking of should be sized to provide all the energy that a house needs during the best irradiation day in the year. I ran few simulation for such a system and find that it works fine. The advantage of this system is:. The way I understand your system it is scaled to never generate more electricity than what you need on a day-to-day basis and therefore you save money by not needing a big battery bank.

My requirement for home is 8 fans, fridge, 8 florescent bulbs, instant geyser.

What will it cost. That it costs, guarantee, and after sales service will be available.? Hello Mathias, regarding the grid tie in Poland, Would it be reasonable to just install the standard hybrid system with a little more battery capacity and also divert energy to some usefull work that can be used later? Maybe you could supply free hot water to all of your neighbors instead of giving the grid free power!

Or any other use that would benefit people around you. Install a driveway heating system just for use when the sun is producing more than you can use. Mathias, I am in the beginning stages of designing a similar system. My intent is to build the system to charge a battery bank that I will attempt to build myself.
