Types of Solar Power Systems
There are three primary types of solar power system for anyone getting into solar to consider. The first are grid-tied systems that contribute to, or use energy from, the utility grid. The second are off-grid systems that are designed to provide a more self-reliant option and third are standalone solar system or off grid solar systems that has no connection to the Grid, and in place of the Electricity Grid supplying your power at night and on very cloudy days you use a bank of batteries to draw power when there is little or no power being generated from your solar panels. This system is generally used by people who have been quoted a very high price to connect to the grid generally because they are in remote locations.
Just how does sunshine become electricity? Here’s an overview of the solar energy facts, the process, and the equipment that can help you generate your own clean, more affordable energy.
Grid-Tied Solar Power Systems
Grid-tied solar power systems generate electricity for your home or business and route the excess power into the electric utility grid for compensation from the utility company.
Galactic Solar Solutions stocks all the components and we assemble complete grid-tied solar packages, so that we can offer them to you at best prices.
We also design and assemble 3kW, 5kW, 6kW, 10kW & up to 100kW solar system packages with best solar panels and latest technology inverters with Wi-Fi trackable options. So you can get best solar power system for what you pay.
Solar power systems generate electricity silently and without any moving parts. Sunlight falls on the solar array and generates DC electricity. That DC electricity is converted into household AC electricity by the inverter. The AC electricity is fed into your electric meter and circuit breaker panel. The electricity either goes to your appliances and lights, or to the grid, or some to each. This happens silently and automatically every day.
At night and during cloudy weather, the solar system’s output is reduced or stopped; however, your home then gets electricity from the utility grid. You are always connected to the grid, so you can have as much power as you need, any time you need it, regardless of whether the solar system is able to put out any power.
HYBRID SOLAR SYSTEM
What is a hybrid system and can I have one of those?
A hybrid system is a grid connects system with back up batteries and is useful in two ways. First and foremost is that if you are putting most of the solar power you make back into the grid during the day as you are at work or school and you are on the new 8 cents feed in tariff its not a bad idea rather than selling power to the grid you may as well charge your batteries with it and then you can use your stored power at night and let the solar recharge your batteries the next day.
Please note that once the batteries are charged you will still export any additional kilowatt hours to the grid, and if the batteries go flat or reach their pre-set limits you will switch back to grid power.
The other handy thing is that in the event of a power blackout you will still have power available, until the battery power is gone or reaches its pre-set limit. This system is only used where the customer has grid or mains power.
Are there any other options available? If you would like to have some backup power available in the event of a blackout (when on grid power) there is a new type of inverter that has an inbuilt battery storage that will give you a limited amount of power in the event of a power blackout.
STAND ALONE SOLAR ( OFF-GRID )
Stand alone or off grid solar systems have become a lot more affordable in the last year or two.
What is Off-Grid solar and should I be looking into it?
Off-Grid or stand-alone solar systems are a solar system that has no connection to the Grid, and in place of the Electricity Grid supplying your power at night and on very cloudy days you use a bank of batteries to draw power when there is little or no power being generated from your solar panels. This system is generally used by people who have been quoted a very high price to connect to the grid generally because they are in remote locations.
How do I know what sized stand-alone system will suit me?
A detailed load analysis is the only way to ensure that your stand-alone system is sized to meet your requirements. This means we have to work out how much your average daily load is and size your system accordingly, some companies charge $300 to do a load analysis (it does take a bit of work) but we do it as part of our quoting procedure.
What about a backup generator?
We always recommend that a customer include a backup generator in the overall stand-alone system. This is because you are bound to get situations where you need to use more power than we have calculated for and or there will be times when we have a long spell of rainy overcast days where the solar panels don’t generate their usual average amount of power per day.
How much will a stand-alone system cost?
It all depends on how much power you need available per day, we have seen prices fall a lot over the last year or so, we have been selling some systems around $25K and others up around $45K, so the answer please submit details and we will come to you and work it out.
