SOLAR TRACKING

HEATING & COOLING, CHARGING EV & PLUG IN’S 

Completely autonomous solar tracking

Our solar tracker uses GPS to automatically calculate the sun’s location from anywhere in the world.The high precision tracking maximises the energy production throughout the day and guarantees a high return on investment.

Why are tracking panels better than stationary?

A household consumes the most electricity in the morning and in the late afternoon – early evening. So this is when you should produce solar power!

 The output of fixed solar panels on a roof facing south follows a sinus shaped curve starting slowly in the morning, peaking at solar noon, and immediately beginning its descent towards evening.
A Heliomotion continuously turning to face the sun starts generating electricity much earlier in the morning than fixed panels, and will continue to do so until much later into the evening.
The extra kilowatthours produced by the Heliomotion coincide very nicely with the peaks in the consumption curve of the typical household: first peak in the morning and second peak
late afternoon – early evening.
With fixed solar panels it is quite likely that the household will have to buy electricity from the grid during those peaks even though they actually produce their own solar electricity – but at
the wrong time of day!

Solar Tracker - Heat Pumps - Air Conditioning

If the electricity is to be used for heating or cooling purposes it can be leveraged by a factor of 3-5 by using a heat pump. This could be an air-out type heat pump for indoor climate control, or a water-out type for heating a water heater. This configuration is a particularly profitable application of the Solar Tracker.

With the solar water-out heat pump system the daily tap water produced from solar energy will be enough for a 4 person family, and the grid fallback feature guarantees hot water to always be available even when sunshine is limited.

 

Grid

The DC electricity generated from the Heliomotion can be used in two main ways: either to charge an array of batteries or to be fed directly into the power grid. The grid-tied installation uses the grid as an energy storage (as a battery). In this configuration the DC output from the PV panels are connected to a Grid-tied Solar Inverter to produce AC power, which is then connected to a power outlet and thereby to the grid.

The power generated from the sun reduces the power needed from the utility. Excess power may spin the meter backwards (called net metering), or be recorded as power credits by the utility company, depending on your agreement with them. Please consult with a representative of your utility company before planning this type of installation.

 

 

 

 

 

 

Solar Air Cooling System 

 

The battery-tied system can also be used for solar powered climate control by connecting it to an air conditioning unit. The more the sun shines on your house the warmer it gets inside and the more you wish to cool it down. The beauty of solar powered air cooling is that when cooling is needed the most you also have the most solar energy available for cooling it.

The Tracker Solar Air Cooling system will offer a compact and reliable solution for home owners to keep their houses nice and cool with free energy from the sun. This is especially advantageous in areas where electricity supply is expensive and uneven during peak hours, typically afternoons and evenings.

 

 

Off Grid 

 

In a battery-tied system the solar energy is first used to power local loads and excess energy is stored in a battery array which is drawn upon when loads exceed available solar energy. When both solar energy and battery capacity are insufficient the system can optionally switch over to grid power automatically, in order to ensure an uninterruptable supply of electricity.

 The solar electricity distributed from the solar station can either be connected to a new power outlet, or to existing power outlets through the building’s fuse box, by a certified electrician. This installation does not require approval from the utility since all solar energy is used locally. The system can easily be expanded if desired at a later stage with additional inverter, battery and/or renewable energy capacity, to supplement a greater proportion of household energy consumption.

How does a Solar Tracker track the sun?

The tracker has an integrated GPS module used to determine the local time, date, latitude and longitude. Using this information the tracker calculates the sun’s position in the sky in order to follow it.

How much does tracking increase electricity production?

Solar tracking increases energy yield by 30-60% per year, compared with a stationary panel facing south with an ideal tilt. The energy increase depends on the latitude where the installation is located, from +25% at the northern equinox to +60% in Scandinavia. The extra energy is generated in the morning and in the evening which matches the consumption curve of a typical household much more efficiently than a static system which peaks at solar noon – often when everyone is out of the house.

How is the Solar Tracker powered?

The solar tracker can be powered from any constant 24 VDC power source, either using the included 24 VDC power adapter or by connecting it to a 24 V battery bank. The permitted input voltage range is 10-29 VDC. Average power consumption is 0.4 watt.

How much wind load is the Solar Tracker designed to handle?

The Solar Tracker is engineered to withstand high wind loads and even the largest PV-6 system can resist wind speeds up to 30 meters per second – equivalent to 67 miles per hour. Should you expect winds in excess of this, it is recommended that you use the provided extension rod to tilt the panels horizontally. This will protect the installation until the storm passes, as this is the optimum position for the installation to resist high wind loads. PV-6 units in the field have survived wind speeds up to 42 m/s, but we do not recommend installations where wind speeds beyond 30 m/s is common.

How does snow impact the performance of the Solar Tracker?

In a snowy climate, the foundation column should be at least 1 metre above ground level to prevent the tracker from getting stuck in the snow during winter. As the panels are at a steep angle in the tracker’s morning and evening positions, most snow falls off the unit and there is usually no need to remove the snow manually. As an added safety feature, the tracker will pause tracking if it is unable to move, for example due to excessive snow or vegetation blocking its path. Remove the obstacles and the tracker will automatically resume normal operation within a few hours.

Does the Solar Tracker work in dry regions?

Yes. Keep in mind that in dry regions it may be necessary to wash the panels every couple of months to prevent dust and sand from building up on the panels. In regions with rain, the solar panels are typically self-cleaning and do not require additional attention.

Can the tracker be reconfigured?

The tracker is designed to work without any reconfiguration. For service purposes the tool Heliocom can be used to communicate with the tracker. Start the tool on a Windows laptop and connect it to the USB terminal on the tracker’s circuit board using a USB cable (Type-A Male to Type-A Male). A description of the tool is available Heliocom Manual.

How long is the design life and warranty of the product?

The Solar Tracker is designed to last for as long as the panels last, typically 25-40 years. We give a 3 year warranty to provide free replacement parts. The warranty appears on the last page of the manual.

The Maysun panels have a 12 year product warranty guarantee on materials and workmanship, and an 80% output guarantee after 25 years.

How far away can a Solar Tracker be placed?

We recommend the power plant is placed within 100 meters of where the power will be used. The cable size can be adjusted to keep transmission losses low between the power plant and the house. A cable with 2.5mm2 thick wires is suitable for distances up to 40 meters, whereas a cable with 6mm2 thick wires is recommended for longer distances up to 100 meters.

Should I choose a grid-tied or a battery-tied system?

Typically, you want to use a grid-tied system if utility power is available, because it has a lower cost and it allows you to automatically utilize 100% of your produced electricity. The surplus electricity not consumed by your household will be sold to the grid.

Battery-tied system are most often used for off-grid installations when there is no access to utility power. They can also provide backup power during blackouts and allow a greater proportion of generated solar energy to be consumed within the household. When considering a battery-tied system it’s important to keep in mind that generated solar energy that is not consumed will be discarded when the batteries are full. Therefore, to make full use of a battery-tied solar system it should be paired with reoccurring daily loads, such as a heat pump or an electric vehicle.

How much battery capacity should I have for an off-grid system?

Since batteries are expensive, storage capacity is an important issue. We offer deep-cycle GEL batteries by default because of their many benefits compared to standard lead-acid batteries.

For backup purposes and cabins without access to a fixed power grid, we recommend at least 5 kWh GEL battery capacity (4pcs 12V x 110Ah battery). Larger needs are usually combined with a larger Heliomotion and a larger battery bank. We typically recommend 5 kWh for PV-2M/3M, 10 kWh for PV-4M and 15 kWh for PV-6M. This allows storage of about half a day’s solar energy.

Which battery type should I use?

We recommend the deep-cycle GEL batteries. They are maintenance free, can be used indoors, have a long lifetime, and are made to withstand deep discharge cycles. They are ideal for solar battery systems.

What is the noise level generated by the system?

The grid-tied microinverters are fanless and make virtually no noise. The battery-tied solar stations have fans which kick in progressively as the inverter load increases, so it should be placed somewhere where the sound doesn’t bother anyone, such as a garage, a shed or a cabinet.

The solar tracker itself is very silent. Listening carefully right next to the tracker, it makes the sound of a distant cicada every 7 minutes or so when it updates its position.

Is it possible to fit solar thermal collectors on the tracker?

Yes, but we have transitioned to primarily focusing on electrical installations, as demand for them have been considerably larger. If requested, we can provide thermal systems under the model names TC-1000 and TC-2000 (TC for thermal collector).

What is included in the package?

See the product page or a description of the packages. When you order a Solar Tracker you can specify what your package should contain. We manufacture power plants for both grid-tied and battery-tied applications in different sizes. The packages can be ordered with or without panels and inverters.

Can a Solar Tracker be installed on a roof?

We advise against installing the Solar Tracker on a roof. A free standing unit on the ground is much easier to install and service.

What happens during a blackout?

This depends on whether you have a grid-tied or battery-tied inverter. A grid-tied solar inverter feeds power to the grid and so during a blackout the production is halted until power is restored. A battery-tied solar inverter works independently of the grid and so it will continue to supply power to connected loads even during a blackout.

How do I use the power from a battery-tied inverter?

A battery-tied inverter creates its own local power grid which is independent from the utility’s grid. To make use of this power an electrician needs to connect the power output from the inverter either to new power outlets or to existing power outlets through the building’s main fuse box. Keep in mind that the 1-phase VAC generated by a battery-tied inverter is not synchronized to the utility grid and so cannot be used in combination with the utility grid to power any 3-phase loads.

How long do the batteries last?

The GEL battery is durable and has a design life of up to 12 years. Each charge/discharge cycle reduces the maximum capacity of a battery, more so the deeper the cycle is. After 750 cycles that are 50% deep, or 1800 cycles 30% deep, a GEL battery will have lost 20% of its maximum capacity. This is called one service life.

When the capacity has fallen beyond what you are willing to accept, it is time to replace the battery. This is usually after two service life cycles have been consumed. So if the average cycle per day is 3% deep then the battery can be considered exhausted after 3600 cycles or 10 years. Keep in mind that GEL batteries must never be left in a discharged state for any longer periods as that will reduce their maximum capacity.
