Solar Grid Tie System

Solar PV systems offer lots of benefits to residential and commercial property owners, most remarkably ensures them a renewable and low-cost energy source for usage. However, a few extra benefits will be available based on the type of solar power system you select, and it is necessary to consider the positive and negative aspects of solar on Grid systems and off-grid systems, in order to choose the best option that is perfect for you.

Solar Grid Tie systems are the most familiar and standard type of solar PV system in use throughout the world. This type of power system keeps connected, or “tied” to the local electrical grid and sends excess power back to it for earning revenue from SRECs (Solar Renewable Energy Credits). The solar on Grid systems are capable to maintain power supply even when the solar PV panels don’t get enough sun exposure and can’t produce the adequate amount of energy to meet the needs. The residential or commercial property that is installed with a solar Grid Tie system is often rewarded by the local utility company for the extra power generation. As long as the solar PV panels produce electricity for the user consumption without any grid supply, the power will be free of cost. Even if the house or business consumes more power than the generated amount, it will be billed at a discount on the local electricity rates for extra consumption through the grid.

Determining the right size of your solar grid-tie system is a lot easier than an off-grid system as the local power company maintains all the power-related details for you. There are different ways that you can find a right solar system of this kind. You can look at electricity bills for several months to find out how much is your monthly electricity consumption in kWh and target a solar on a Grid system that would meet your average electricity needs per month.  

Once you are done with this, you may like to know how small or large a solar on-grid system will be or to make sure that you have enough space on the ground or roof to accommodate a system like this. Your electrician may recommend you a few things to bring down your power usage or replace the existing appliances in your home to make it more energy efficient.

If your local power supply company follows a tiered billing structure which means you are charged a specific rate for baseline usage and then bigger rates for exceeding that baseline or using a certain percentage of power over the baseline, you should select a solar grid-tie system that reduces the over usage and higher electricity rates which results in a greater savings on your investment. The below-given steps will help you easily determine the right size of solar grid-tie system you need for your building.

1. Know your average electricity usage per month by going through your electricity bill for several months.  It will be mentioned in kWh.
2. Calculate your average electricity usage per day (divide your monthly average kWh by 30).
3. For your location, find the average peak sun hours per day (kWh/sq.m/Day).  
4. Determine the solar grid-tie system size (AC kW) to meet 100% of your electricity usage (divide your daily average electric usage by the daily average peak sun hours for your location).
5. Divide the result in AC by .77 to get a reduced power rating factor for the system components. It may happen due to temperature, wire defect, component ineffectiveness, etc.
6. Multiply the above result by 1000 to get watts (AC output) of the system.
7. Divide the alternating current output of a solar on a grid system by the watt of the module that you desire to use in order to know the exact number of modules you need to cover 100% of your electricity needs.

Solar Water Heating System

Each time you feel the warmth of the sunrays on the rooftop or courtyard, it reminds you of a natural energy source is always there for the hot water and space heating needs at your home. It is available in an unlimited amount and at free of cost!

You may be aware that it is possible to convert sunlight into electricity using the solar panels, but it may feel shocking & interesting for you that the same can generate heat energy for solar water heating and space heating. Solar water heating is a cost efficient technology in use to produce heat energy in abundance for your domestic or commercial needs. It will save money on utility bills which will ultimately pay for the SWH installation cost.

Selecting the best solar water heating system may not be easy without proper knowledge; it is recommended to seek for a specialist’s help, who has experience of installing the SWHs and providing quick consultation on them. There are two widely used varieties of solar water heating systems available for your choice.  A Passive solar water heating system does not require any pump induced energy but, the natural gravitation force to help the water circulate from collectors to the tank. It has less number of mechanical parts, reduced maintenance/servicing cost and low expenses for initial setup. Whereas an Active solar water heater is a more expensive, yet energy efficient type having pumps and controls to aid in the process of water circulation.

Both of these solar water heating systems include two key components – a solar collector and a water storage tank. The solar collectors capture the sunrays before converting them into heat energy. They can be of the following types:

• Flat plate collector:  well insulated and glazed collectors following a flat-plate assembly method
• Evacuated-tube collector: the transparent and energy efficient glass tubes arranged in rows with little scope for heat loss from them.
• Integral collector or Batch collector: a system made of single or multiple tanks or tubes kept in an insulated box for long term water storage. It does not fit cold climates due to the risk of freezing pipes in heavy cold condition.

While looking to pick up the best SWH for your home, you need to review the solar water heating systems from all angles. It is the geographical region, climate condition and your home’s position that will be crucial in deciding which solar heating system will be perfect for you.

The active solar heating systems can make up for your extra expenses with lowered utility bills per month. They can be of the following types:

• An indirect circulation system uses a heat exchanger to transfer heat into the water storage tank from a nonfreezing fluid circulating in it. This kind of system suits the very cold regions where the temperature may fall drastically to cause the pipes freeze at any time.
• A direct circulation system uses pumps to let the water circulate through the collectors and then flow back into the storage tank. They function well in mild climates where there is no risk of temperature going below the freezing point.

Passive solar heating systems are normally more reliable, durable, less costly to install, but they are not as efficient as the active ones.  They can again be of two types:

• A thermo-syphon passive system makes the hot water rise from the collector to the crest of a tank without the use of a pump. In this case the collector is fitted underneath the storage tank to make use of the natural gravitational force.
• An Integral collector-storage passive system assembles hot water in storage tanks or tubes that are placed inside an insulated box and fits the best in mild weather conditions.

An apparent problem in using solar energy is the lack of control on the weather. If you reside in a dark and cold area with only a few sunny days experienced in a year or there is no south facing roof in your residence then the solar water heating may not prove to be as effective as it should.

If all these details can’t eliminate your doubts or confusion, don’t feel worried at all! Solar water heating systems have been in use for a long time but are not extensively used everywhere, therefore asking for advice and guidance from 123 Zero Energy would be a worthy step to take before looking to invest in one.

6 Myths And Facts About Geothermal Systems

As the world focusing more on renewable power sources, geothermal energy & systems are getting more importance amongst homeowner’s worldwide. Geothermal energy isn’t just a renewable source and is incredibly eco-friendly, but it’s also the most cost-effective substitute to typical energy supplies.

However, a great deal of info out there on geothermal cooling and heating is based on out dated info, or outright myths. Here in this post we will talk about both the myths and facts regarding geothermal systems.

Myth: Since they employ electricity, geothermal systems aren’t considered as a renewable technology.

Truth: Geothermal systems employ only one unit of electrical energy to produce 5 units of heating or cooling from the earth to your home.

Myth:  Photovoltaic (PV) & wind power are more preferred renewable technologies in comparison to geothermal system.

Truth: Geothermal systems remove 4 times more kilowatt-hours of consumption from the electrical grid per dollar invested than photovoltaic & wind power integrate to the electrical grid. The other technologies out there can play a crucial part, but geothermal is often the most affordable way to decrease environmental effect of conditioning spaces.

Myth: Geothermal heat pumps are ear-deafening:

Truth: For your knowledge, geothermal systems operates very quietly and there’s no appliances to bother your neighbors.

Myth: Geothermal systems wear out eventually

Truth: When it comes to lasting, earth loops can last for several generations. The heat exchange appliance usually lasts decades, since it’s sheltered indoors. When it doesn’t require to be substituted, the expenditure is much lesser than placing in a complete new geothermal unit, since the loop is the most expensive to set up. New technical guidance eradicate the problem of thermal storage in the earth, so heat can be interchanged with it obscurely.

Myth: Geothermal system work only in heating mode

Truth: Absolutely wrong! They run just as efficiently in cooling & can be made to need no supplementary backup heat supply if wanted, although some consumers decide that it’s more affordable to own a small backup unit for only the coldest days.

Myth: Geothermal systems consumers too much water:

Truth: In reality there’s no water consumed by geothermal systems. If an aquifer is employed to interchange heat with the ground, all the water is returned to that same geological formation. Earlier, there were some “pump & dump” operations that squandered the water after passing through the heat-exchanger, but today the scenario has changed a lot. When used commercially, geothermal systems actually eradicate millions of gallons of water that’d otherwise have been vaporized in cooling towers in conventional systems.

Hence it is essential to know the true facts and help people understand around you about the positive effects of energy exchanges around us.   So it’s the old saying Geothermal Energy is always Safe and Renewable.

Benefits of Domestic Solar Water Heating Systems

The sun is the main source of energy in the solar system. It offers plenty of free and green energy to the earth even though not making it fall evenly everywhere. The large variance in the sunrays available in our planet’s lower and higher altitude has been a cause of concern for household owners.  However, the inventive solar water heating systems are helping them generate sufficient amount of heat energy with the solar collectors for domestic use like water heating, space heating etc. Some of these domestic SWHs are tankless and others have water tanks positioned normally on basement or roof area to   store water for the future.

What Actually are Domestic Solar Water Heating Systems?

These are solar powered heating systems technically designed with components like solar collectors, heat exchangers, pump and controller for domestic applications. Based on an effective technology and taking in free source of energy, the domestic solar water heating systems bring a significant reduction in the utility bill as well as carbon footprint. There are flat plate SHWs and evacuated tube collector SHWs which homeowners can choose and mount on their wall or roof. They can also be integrated with any existing hot water systems for assured performance.

Basically, domestic solar water heating systems are capable to meet around 0.33% of the total hot water demands of a 4 member family. More elaborately, investing in a solar water heating system will lower the annual energy bills by £55 -80 for a three-bedroom home in a semi-detached state. The solar water heating system users also qualify for the Renewable Heat Incentive (RHI) program, which is mainly designed by local government to reward financially and encourage households to heat their homes with solar energy.

How Do Domestic Solar Water Heating Systems Function?

Domestic SHWS gather the heat coming from the sun through solar collectors which are normally fitted to the roof at the best angle to receive maximum possible sunlight. They can even be placed on wall or ground to get high exposure to the sunrays. An immersion boiler or heater can be used along with them to raise the water temperature whenever required.

The solar thermal collectors used in SHWs are of two types: evacuated tubes collectors and flat plate collectors. They differ in configuration but have the same function. The evacuated tubes collectors contain highly insulated and replaceable vacuum tubes assorted in different sizes to fit domestic heating needs whereas the flat panels contain inexpensive flat glazing collectors which look like solar PV panels and are installed on the room for energy absorption and heat generation.

In the installation of SHWs, routing is done from the collectors to a hot water tank using high insulate pipes. The unheated water from the bottom of the tank is pumped and flown through the collectors so that it can receive the generated water and go back to the top of the hot water tank storage.

 Top Benefits of Domestic SHWS

• They ensure hot water around the year.
• They lower energy consumption for domestic hot water needs.
• They bring down carbon emission and keep the environment safe.
• In comparison to other renewable energy heating solutions, domestic solar water heating systems have great durability and reduced maintenance expenses.

How Does Solar Grid Tie System Work ?

On-grid systems or solar grid-tie systems are the solar PV systems that only generate power whenever the utility power grid is available. In fact, they must connect to a power grid to operate. Whenever you are overproducing power, these systems can send excessive power generated back to the grid for later applications. Now-a-days most of the solar systems are installed fall into the grid tie category. They are directly tied into the existing electrical grid and need that the electrical grid is running for the solar system to generate electricity. 

Hence, it’s much more efficient to be hooked to the utility grid than other available options. If you’ve solar grid tie system, you can able to produce more energy during the sunny days and build up energy credits. However, the ultimate goal of the solar powered system on the grid is to produce as much power over a twelve month period as you utilize. 

How Does On the Grid System Work During a Sunny Weather -

Solar systems generate electricity silently without any moving parts. During the sunny day, the sunlight directly falls on the solar array and then generates DC energy. After that, the DC energy will be converted into household 120V AC electricity through the inverter. After the generation of AC electricity, it will be fed into your electric meter and circuit breaker panel. Then, the electricity for your household either goes to your lights and appliances or to the grid. All these processes happen silently and on an automatic way daily. 

How Does On the Grid Work at Night or a Cloudy Day -

During cold weather and at night, the output of the solar powered system is reduced or stopped. But your home will get the necessary electricity supply from the utility grid. This means, your power supply system is always connected to the grid so that you can have as much power as you need any time whenever it’s needed; regardless of whether the solar system is able to put out any power. 

Besides, a standard grid tie system will not produce power unless and until the grid power is available during a utility power breakdown. If this is the issue, you can utilize grid tie system with battery backup. When utility grid power is available, the system works like a standard grid tie system and sends excess power back to the utility. Again when the utility power fails, the battery backup can allow the solar array to continue to supply power to the home during the day time and can supply selected circuits within your home during the night. Once the utility grid system starts up, the system switches back to its normal operation automatically! 

Conclusion -

For many people, a grid tie solar system is the key to ensuring long-term security and providing a good investment alternative to businesses, farm or home. Even, the systems can offer low maintenance costs as there are fewer components that may need to be replaced in the future. Therefore, it’s time to take a look at solar on grid systems or solar grid tie on 123 Zero Energy and make an investment suiting best your budget and daily requirements.
