aluminum panels Before You Buy a Solar Water Panel System

The system is at home.But before we go out and buy any systemHere are some tips to help you find the best options.1.Solar panels are usually 1 m wide and 2 m long.Depending on how much hot water you need,1 to 3 panels are usually enough.The digital panels needed can be easily calculated by reputable solar installations.If your current solar energy doesn't make the water hot enough,Before getting a new system, try adding more panels to the system first.To make sure the new panel fits the old systemIt is best to use the same supplier.2.There are two main solar hot water heating technologies:Flat panel and evacuation tube technology.,The older the two are.It is also the most practical and widely used.Although it is not so effective to heat the water in rainy or windy conditions,Its solid design and quick return on investment make it a good solution in the sun,warm regions.a.k.a."Centralized collector" has two advantages:They are effective in heating water in weak sunlight and they are not easy to freeze in winter.The disadvantage of using a centralized collector is that the tube costs more and can be easily damaged (But they can change).3.Your solar hot water system can be set in two ways:Or the tank inside.Separate from the panel,Or the panel directly above the roof on the tank.On-:a.k.a.Here,The tank is mounted directly on the panel on the roof.It is a passive system because it only uses the pressure and natural physics of water to keep the flow of water-When the water is heated and the tank rises,It sucks cold water from the power supply,It flows through the solar collector and into the tank.If the tank is installed too far from the shower and other hot water outlets,This may not be the best choice.The farther the tank is from where it is needed,The longer it takes to receive water,It will cool slightly from passing through the pipe.The tanks coming out of the roof are not a very beautiful sight either.:a.k.a.Here,Solar collectors on the roofInstall your current tank with the tank.Water tanks for collecting heated water,A small electric pump is needed.Although electricity is used to pump water in the system,The cost is recovered from increasing energy savings.As the indoor water tank is better protected from elements and insulated hot water.The advantage of the active system is that you can put the tank in the best position,Hot water is therefore available quickly.Also,There's usually construction-In Frost protectionIn cold conditions, warm water is pumped back to the collector to prevent them from frost and cracking.The only downside to the active solar water heater is the cost.4.All kinds of paint can be placed on the solar water board,This determines how the water is heated and how long the panel will last:Black Paint:This is the lowest grade paint.Cheap though,A lot of powerful,Direct sunlight requires heating of water.It's good to use it in heat,Sunny climate,But it will generate enough heat in the cooler.Temperate Zone.Anodized coating:Also known as "selective coating"They are very common in residential hot water systems.Solar water plate anode alumina, sometimes copper.When observed under a microscopeThe coating creates a very uneven surface,Cause a larger surface area to shine for the Sun-This allows the panel to absorb all solar heat up to 80%.The anodized coating can be easily damaged,But their protective glass covers helped them last for years.Black Chrome:This is an advanced technology.S.Family without sunshineFacing the roof.Like selective coatingBlack Chrome is excellent to absorb any sunlight,Even in cloudy conditions.The only problem with this coating is its harmful health risks in the manufacturing process.This makes it less popular in Europe,Where technology is better.Such as selective paint,is available.5.In extremely cold areasFrost can be a factor.In winter,Heavy frost can freeze the water in the panel.When water freezes,It expands and may crack the panel.This can be avoided in two ways:Either close-Loop system or Frost valve.If you live in an area with a lot of frostclosed-is best.Here,Not water,Ethylene glycol is placed in the panel.When the ethylene glycol is heated, it is transferred to a heat exchanger, which heats the water.Though closed-The cycle system is more expensive,Ethylene glycol will never freezeMake the panel not easily damaged by frost.If you only get frost once in a whileis sufficient.As the temperature drops,Open the frost valve,Panels that allow water to be released and prevent freezing damage.Just make sure the frost valve has a manufacturer's warranty on investing in one.What have we learned?Before you plan to purchase and install the solar panel systemAsk yourself the following questions to help you make an informed decision:So you can see,There are many determinants when getting a solar panel system home.With your new-Discover knowledge,Hopefully you can buy the right system for your situation instead of being ripped off in the process.
