Introduction


What is a Solar Water Heater? Solar water heaters use the solar energy from the sun to generate heat (not electricity) which can then be used to heat water for showering, space heating, industrial processes or even solar cooling. They utilize a pump to transfer heat from the collectors to the water to be used, which is stored in a remote location away from the collector.
One advantage of a solar water heater is that they can store the hot water anywhere, even far away from the actual collectors which receive the sunlight. This allows for strategic placing of the tank close to where the water will be used so that it will not take long for the hot water to flow from the tap.
The tanks used to store the hot water may also have backup heating systems in case of cloudy days where there is not enough heat to meet the demands of the user. Another advantage of the solar water heater is winterization. Since the working fluid is an intermediate fluid, a non-toxic inhibited propylene glycol can be used to prevent freezing. Although there are less hours of sunlight during the cold winters in the north, there is still a lot of heat which can be collected with a vacuum tube solar water heater.

Vacuum Tube vs Flat Panel
Efficiency
Vacuum tubes are much more efficient than flat panel collectors. Heat gained within the tubes is not so easily lost through the vacuum, while in a flat panel collector, heat can be lost as rapidly as it is gained, especially in high temperature applications.
Flat panel collectors perform poorly in low irradiation settings. When there's a lot of clouds, or the sun is on the horizon, the flat panel collectors retain little or no thermal energy because any heat slowly gained is quickly lost through the non-insulated components of the collector's surface.
In high temperature applications, such as home heating or absorption cooling, vacuum tube solar water collectors outperform flat panel collectors in every circumstance.
When it comes to flat panel solar collectors, the absorber area is nearly identical to the gross area. On vacuum tube collectors, the absorber area tends to be around only half of the gross are of the collector. When comparing the two through the SRCC efficiency equations, the vacuum tube collector will appear to have a much lower efficiency due to these gaps between the tubes and the manifold.
The gaps between the tubes in vacuum tube collectors are not as much of a problem as would be expected since the sun is only directly above in the sky for a short period of time. As the tubes passively track the sun as it moves across the sky through the day, more of the sunlight which passes between the tubes when perpendicular gets absorbed through the sides and backs of the tubes, rather than passing between the tubes. The transverse incident angle modifiers actually gain so much extra sunlight during the morning and evening that it greatly reduces the gap between the flat panel and vacuum tube collector overall efficiencies throughout the day.
There is a solution to the gaps between the tubes in a vacuum tube collector. Reflectors can be mounted behind the tubes, so that any sunlight not absorbed will reflect back towards the tubes and have a 2nd chance to be absorbed while passing through. This is especially effective when the sun is perfectly perpendicular to the collector, as this is when the gaps are most exposed. However, when the sun is at a high angle, the reflectors do not make any difference as the tubes themselves absorb all of the energy on the first pass from the passive tracking.
It is estimated that the reflectors provide an additional 50% extra sunlight to the tubes for the overall day. The theoretical maximum gain, based on the gaps in the Solar collectors is about 76%. With reflectors, it is easy to conclude that vacuum tube collectors outperform flat panel collectors even at low ?T between the collector and the ambient.
Cost
Flat panel collectors are more expensive than vacuum tube collectors since they contain a lot more expensive materials such as copper piping. It will not be uncommon for a flat panel collector to cost 50% or more than a vacuum tube collector of similar size.
Flat panel collectors also require a lot more fluid to fill all of the extra pipes, which means more antifreeze expenses when it comes time to changing out the fluids.
If space and not cost of the collector is the determining factor in choosing flat panel over vacuum tubes, it should be noted that a reflector set for a solar collector only costs an additional 8-10% towards the final cost of the vacuum tube collectors. These reflectors, which give around 50% more sunlight, make up for the gap in gross area efficiency, and still provide nearly the same or more heating power at low temperature applications, and of course a lot more heating power at high temperature applications.
Installation & Maintenance
Flat panel collectors come as one heavy piece. They must be carried up to the roof where they will be installed and mounted as one piece. Should any damage occur to the collector, the entire collector is rendered useless. A large hailstorm can bring death to a solar water heating system consisting of flat panel collectors, and will require full replacement to bring it back to efficient operation.
Alterna Energy Solar Vacuum Tube Collectors come in different pieces. The stand is put together and mounted to the roof, and then tubes are plugged into the collector. If a tube breaks from bad weather it can easily be replaced with a spare tube. Alterna Energy provides extra tubes with each collector as insurance during shipment, and any extra tubes that make it to the customer can be kept as spares in the case of breakage during installation or use.
Although the life of a solar water heater is long, there will eventually come a time when it needs to replaced. However, vacuum tube collector parts can be replaced as needed. If some tubes go bad, they can be swapped. If the manifold gets corroded from poor heat transfer fluid quality, it can be swapped and the tubes kept. If something goes wrong in a flat panel collector, the entire unit will likely need to be replaced.
Installation of a vacuum tube collector is also much safer. The heat absorbing into the inside of the tubes does not rapidly transfer to the outside of the tubes. Therefore, a very hot tube can be picked up by hand and will feel cool to the touch. A flat panel collector in the sun will be hot and difficult to work on during the day.
Climate
Vacuum tube collectors hold up against high winds better than flat panel collectors since they have gaps between the tubes which allow for the wind to pass right over them. If the wind catches a flat panel collector just right, it could be sent flying through the air, resulting in damage to the roof it was mounted to and to the surrounding areas.
The question of snow comes up a lot. The argument of flat panel collectors is that when they are covered with snow, any light that passes through the snow to the collector will result in the glass heating up, and thus the snow melting. The collector can then resume full efficient solar collection.
A vacuum tube collector doesn't really need this heat loss feature. Snow falls between the tubes and does not pile up on the collector, allowing the collector to gather heat from the sun even while snow is falling from the sky. In the event that there is enough snow build-up to actually cover the tubes, the collector will continue providing heat from any sunlight that passes through the tubes, rather than dumping it back to the snow. Any light stopped by the snow, will convert to thermal energy and melt the snow from the tubes.
Savings with a Solar Water Heater System
Solar water heaters provide an efficient means of collecting free energy from the sun. The average household spends 30% of their utility bill on water heating. Minimal operational costs and an extended lifetime of solar water heaters provide for a worthwhile investment for home owners and businesses which utilize a lot of hot water.
The amount of energy savings per year will depend on the amount of solar insolation in the area where the solar water heater is installed, the type of weather around the collectors and the amount of power of the system.
As an example of potential savings with using a solar water heater, below is an analysis for a 300 Liter solar water heater system installed in Huntsville, AL. This system analysis assumes that all hot water is used per day, and that the amount of solar energy gained would have been needed in the case of a standard electric water heater (some households may use more or less)

As shown in the table above, a solar water heating system easily pays for itself within 4 years. Not only are the cost savings significant, but the possible life of the stainless steel hot water tank justifies the cost of the system on its own. A typical, cheap glass enamel water heater needs replacing about every 7 years. The stainless steel tank is expected to last at least 15 years, and can last 30 years or more if the sacrificial anode rod is replaced on a timely basis. And since the electrical backup element is hardly ever used in a solar water heating system, it hardly ever needs to be replaced, unlike in a traditional electric water heating system.
The Federal Government is also currently paying a 30% rebate on solar water heater installations (cost of product and installation costs). It will currently expire in 2016, however, the government has been extending the rebate on solar water heater systems for a long time and it would not be unlikely for it to extend the credit beyond 2016.
Total Cost Savings of a Solar Water Heater System over 15 Years
Expense Standard Electric Heater Solar Water Heater
Cost of System & replacement systems $1131.43 $2499.00
Operating Costs $9803.70 $270.00
*Maintenance $88.12 $164.80
Total Costs $11,023.25 $2933.80
30% Government Rebate - -$749.70
Savings in 15 Years - $8839.15
*Maintenance assumes electric water heating element replacements on standard heaters are required once for each tank during its lifespan. Solar water heaters assume 1 gallon of propylene glycol changed every 5 years and the anode rod changed every 3 years.

Sizing a Solar Water Heater System
The size of a solar water heating system can depend on many factors such as location, hot water consumption per day, desired average water temperature and time of year. For a general sizing, follow the guide in the table below. If you want hotter water, add reflectors or additional tubes to the system. If you want more heat in the winter, angle the collector steeper towards the horizon.
General Tank Sizing
The first step to finding out how large of a system is needed is by calculating the amount of hot water used per day or per week and dividing it into a daily average. The chart below may be used for figuring out average hot water consumption per person and per device. The chart assumes the hot water tank contains 50°C / 122°F water.
Hot Water Usage per person/device
10 Minute shower @ standard 3.8 gpm with 38°C / 100°F 95 Liters
10 Minute shower @ low flow 1.6 gpm with 38°C / 100°F 47 Liters
1 Bath @ 42 Gallons 159 Liters
Washing Dishes by Hand with 38°C / 100°F @ 5 gallons per minute 12 Liters per minute
Dishwasher Load @ 15 gallons per load 57 Liters
Top Load Washing Machine (one load) @ 15-20 Gallons 57 - 76 Liters
Front Load Washing Machine (one load) @ 8-15 Gallons 30 - 57 Liters

Example of Calculating Hot Water Usage
As an example, let's say we have 2 people living in a home. Each day they both take a shower, 1 at 5 minutes and the other at 10 minutes, with standard water flow. One person takes a bath per week. They run their dishwasher once per day and they do 2 loads of laundry a week with a top load washing machine.
Example of Hot Water Usage for a 2 Person Home
Activity Times per Week Consumption per Activity Consumption Per Week
10 minute shower 7 95 Liters 665 Liters
5 Minute Shower 7 47 Liters 329 Liters
Bath 1 159 Liters 159 Liters
Dishwashing 7 57 Liters 399 Liters
Laundry 2 67 Liters 134 Liters
Total 1686 Liters
Per Day 241 Liters
As per the above example, this household could use a 200 Liter solar system as an undersized, which will require some backup heating, or it can use a 300 liter system, which will allow for a little extra usage and hardly any backup heating. Most people tend to oversize their systems, so for the sake of continuing the example further, we will assume a 300 liter system is chosen.

General Collector Sizing
Once the needed tank size is known, then the solar collector can be sized accordingly to the amount of water needed to be heated. The number of Solar tubes needed depends entirely on solar insolation and weather.
Using the solar insolation map, an approximate amount of yearly insolation for your area can be determined. Find your location on the map, and then use the chart to determine how many tubes are needed. The chart includes approximate weather data based on location on the map.


Liters of Water Heated to 50°C / 122°F based on Insolation
Insolation Assumed Inlet Water Temperature Liters of Water
5.0 40°F 6.5 Liters
5.5 45°F 7.5 Liters
6.0 48°F 8.5 Liters
6.5 51°F 9.5 Liters
7.0 53°F 10.75 Liters
7.5 55°F 11.5 Liters
8.0 58°F 13 Liters
8.5 60°F 14 Liters
Example of Sizing the Solar Collector
Let's assume that our example household is located in Chicago, IL. This area is about a 6.0 kw-hr/m2 area. They would require 1 tube per 8.5 liters of water to be heated which comes to 300 liters / 8.5 liters = 35.3 tubes. For the sake of even numbers, the household would most likely choose 2 of the 20 tube collectors, for a total of 40 tubes or if perfection is not necessary on the roof, a 15 tube and 20 tube collector could be chosen.
